FIELD widgets displaying ONE_TO_MANY relations now show a "See all"
action button (arrow-up-right icon) that navigates to the record index
with filtered relations.
### Demo
https://github.com/user-attachments/assets/fd632553-70e3-4757-8f26-80aa8d2ce0d2
### Changes
- **`WidgetAction` type**: Added `'see-all'` to `WidgetActionId`
- **`useWidgetActions` hook**: Returns `'see-all'` action for
ONE_TO_MANY relation fields (position 0, before edit)
- **`WidgetActionFieldSeeAll` component**: Renders the navigation button
with:
- `IconArrowUpRight` icon
- Link computed using same logic as `RecordDetailRelationSection`
- Hover visibility behavior matching existing edit button
- **`WidgetActionRenderer`**: Added case for `'see-all'` action
- **Storybook**: Added `OneToManyRelationFieldWidgetWithSeeAllButton`
story verifying button visibility and well-formed link
### Link computation
Uses the same filter URL pattern as `RecordDetailRelationSection`:
```typescript
const filterQueryParams = {
filter: {
[relationFieldMetadataItem.name]: {
[ViewFilterOperand.IS]: {
selectedRecordIds: [targetRecord.id],
},
},
},
viewId: indexViewId,
};
const filterLinkHref = getAppPath(
AppPath.RecordIndexPage,
{ objectNamePlural: relationObjectMetadataItem.namePlural },
filterQueryParams,
);
```
The "see-all" action is shown regardless of field read-only status since
it's a navigation action, not an edit action.

## Summary
Moves the custom ESLint rules from `tools/eslint-rules` to
`packages/twenty-eslint-rules` for better organization within the
monorepo packages structure.
## Changes
- Move `eslint-rules` from `tools/` to `packages/twenty-eslint-rules`
- Use `loadWorkspaceRules` from `@nx/eslint-plugin` to load custom rules
- Update all ESLint configs to use the `twenty/` rule prefix instead of
`@nx/workspace-`
- Update `project.json`, `jest.config.mjs` with new paths
- Update `package.json` workspaces and `nx.json` cache inputs
- Update Dockerfile reference
## Technical Details
The custom ESLint rules are now loaded using Nx's `loadWorkspaceRules`
utility which:
- Handles TypeScript transpilation automatically
- Allows loading workspace rules from any directory
- Provides a cleaner approach than the previous `@nx/workspace-`
convention
## Testing
- Verified all 17 custom ESLint rules load correctly from the new
location
- Verified linting works on dependent packages (twenty-front,
twenty-server, etc.)
## Context
Now that RLS predicates are applied, creating a record through the FE
(which is empty by default) is failing if your role has predicates and
your input does not respect them (which will always be true since, as
said above, input will be pretty much empty)
## Implementation
- Moved isMatching* filters to twenty-shared
- Implemented isMatchingRlsPredicates utils in the backend (ORM) to
check before insertion/update if the record is matching the current user
role Rls predicates, reusing the isMatching* filters utils moved to
twenty-shared
- Frontend now applies RLS predicates before creating a new record
(similarly to what we do with view filters)
Note:
It seems composite were not properly handled with view-filter insertion
logic, since I'm reusing the util for now, the issue remains for RLS and
will need to be addressed
Upgraded to Storybook 10. We still use `@storybook/test-runner` for
testing since it appears it'd require more work to move from Jest to
Vitest than I initially anticipated, but I completed this PR to fix
`storybook:serve:dev` - it takes time to load, but it works the way it
used to with Storybook 8.

# Introduction
In this pull request we're introducing new standard page layout, tabs
and widget ( 1 page layout, 1 tab and 8 widgets ) and also a new
opportunity field
Also now prefilling new records, 6 opportunities and a dashboard.
## Standard declaration
### New workspace creation
Relies on existing standard declaration builder
### Backfill command
We've been hacking through the standard builder in order to extract only
the standard page layout entities, updated their entity dependencies to
match the workspace ids so the validation passes
## Remark
- Refactored the `PageLayoutWidget` configuration type to be dynamically
typed through a generic discriminated union

Upgraded from 8.6.15 to 9.1.17 in two steps:
- 8.6.15 -> 9.0.0
- 9.0.0 -> 9.1.17
I had to disable `storybook-addon-cookie` since it is not supported for
Storybook 9. However, I do intend to upgrade to Storybook 10 when this
is merged, so we can replace the aforementioned add-on with this fork
specifically created to support Storybook 10 and above:
https://www.npmjs.com/package/@storybook-community/storybook-addon-cookie.
Additionally, once we upgrade to Version 10 successfully, I will start
looking into integrating the official Vitest add-on.
I introduced a bug in the chart sorting in this PR:
https://github.com/twentyhq/twenty/pull/16794
This PR fixes this.
The sorting on the first axis is already done by the group by for
FIELD_ASC and FIELD_DESC. It is sorted also for the second axis but in
each group.
For instance, if I create a graph that displays the amount of sales on
each day of the week grouped by vendor
I can have for:
Monday: Vendor B, Vendor C
Tuesday: Vendor A, Vendor B
Wednesday: Vendor A, Vendor C
...
Inside each day the order of the vendor is correct, but by looking at
only one day, I can't know the order of all the vendors.
That is why we always need to sort the second axis.
- Axis labels now respect `axisNameDisplay` config when chart has no
data (previously always showed both) - fixed for bar and line charts
- Horizontal bar charts now correctly map axis settings to visual
positions:
- "X axis" setting → bottom axis (value)
- "Y axis" setting → left axis (category)

https://github.com/user-attachments/assets/5bf32294-9a5e-4aa6-b3fd-0d4e33608d14
- Add widget validation
- Remove 'None' option for primary axis group by
- Fix error message parsing by passing the operation type in
`useMetadataErrorHandler`
## Description
SELECT fields have a defined option order that users expect to see
reflected in charts.
This PR allows sorting by that position and also enables custom manual
ordering.
## Video QA
### Reordering on primary axis
https://github.com/user-attachments/assets/994f515e-19cb-4a5e-b745-e8c77e92ae0b
### Reordering on secondary axis
https://github.com/user-attachments/assets/444c16f2-1920-4dc4-8b42-312d520ab43b
Note: The colors in the graph will match the colors of the select
options, but this will be done in another PR

Removes the background color logic that was incorrectly added to
PageLayoutGridLayout in PR #16870. Grid layouts are only used for
dashboards where widgets have their own background colors set in
WidgetCard.tsx, so the container background was causing visual
mismatches in padding/gap areas. The background logic remains correctly
applied in PageLayoutVerticalListViewer and PageLayoutVerticalListEditor
where widgets need to inherit the container background.
---------

Closes [2029](https://github.com/twentyhq/core-team-issues/issues/2029)
Widgets now use a white background on mobile and in the side panel,
while keeping gray in the side column. Background colors are set at the
parent container level (PageLayoutVerticalListViewer/Editor) so widgets
inherit the correct background, centralizing the background logic in the
container components.
Other variants (dashboard, record-page) specify their own background
color inside `WidgetCard.tsx` file, so we should not have any
regressions.

Closes [2021](https://github.com/twentyhq/core-team-issues/issues/2021)
Field widgets now show the pen button by default on mobile devices.
Previously, the button was only visible on hover, which doesn't work on
touch devices. The button remains hidden on desktop until hover,
preserving the existing desktop behavior.

Closes [2030](https://github.com/twentyhq/core-team-issues/issues/2030).
Determines if a widget is the last visible widget in its parent tab. The
hook:
- Finds the tab containing the widget
- Filters widgets based on visibility rules (respects conditionalDisplay
and edit mode)
- Returns true if the current widget is the last in the filtered list
- Updated `WidgetCard`: Added isLastWidget prop to conditionally apply
border-bottom for the side-column variant
- Updated `WidgetRenderer`: Integrates the hook and passes isLastWidget
to WidgetCard
The useInlineCell hook was only managing the dropdown focus state
(activeDropdownFocusIdState/previousDropdownFocusIdState) but not the
focus stack (focusStackState). Since the hotkey system checks
currentFocusIdSelector which reads from focusStackState, closing an
inline cell in the side panel would leave the focus stack in an
incorrect state, causing hotkeys to not work properly.
This fix adds proper focus stack management:
- openInlineCell: pushes the inline cell to the focus stack
- closeInlineCell: removes the inline cell from the focus stack
Fixes#16224
### Tests Added
- Added unit tests for
[useInlineCell](cci:1://file:///Users/apple/WebstormProjects/twenty/packages/twenty-front/src/modules/object-record/record-inline-cell/hooks/useInlineCell.ts:15:0-83:2)
hook to verify focus stack management
- Tests cover: opening inline cell, closing inline cell, and full
open/close cycles
- Tests ensure `focusStackState` and `activeDropdownFocusIdState` are
properly synchronized

Had to close the other PR since I messed up re-basing somehow:

Closes [1957](https://github.com/twentyhq/core-team-issues/issues/1957).
`getWidgetCardVariant` now returns `side-panel` for mobile and right
drawer instead of returning `record-page`.
Added stories to WidgetRenderer.stories.tsx because WidgetRenderer is
where getWidgetCardVariant is called and the variant is applied. These
stories test the actual behavior (mobile/side panel triggering
side-column variant) rather than just visual appearance, following the
existing pattern of individual behavior-testing stories in this file.
## Summary
This PR enforces the use of `@/` alias for imports instead of relative
parent imports (`../`).
## Changes
### ESLint Configuration
- Added `no-restricted-imports` pattern in `eslint.config.react.mjs` to
block `../*` imports with the message "Relative parent imports are not
allowed. Use @/ alias instead."
- Removed the non-working `import/no-relative-parent-imports` rule
(doesn't work properly in ESLint flat config)
### VS Code Settings
- Added `javascript.preferences.importModuleSpecifier: non-relative` to
`.vscode/settings.json` (TypeScript setting was already there)
### Code Fixes
- Fixed **941 relative parent imports** across **706 files** in
`packages/twenty-front`
- All `../` imports converted to use `@/` alias
## Why
- Consistent import style across the codebase
- Easier to move files without breaking imports
- Better IDE support for auto-imports
- Clearer understanding of where imports come from
Fixes https://github.com/twentyhq/twenty/issues/16110
This PR implements Temporal to replace the legacy Date object, in all
features that are time zone sensitive. (around 80% of the app)
Here we define a few utils to handle Temporal primitives and obtain an
easier DX for timezone manipulation, front end and back end.
This PR deactivates the usage of timezone from the graph configuration,
because for now it's always UTC and is not really relevant, let's handle
that later.
Workflows code and backend only code that don't take user input are
using UTC time zone, the affected utils have not been refactored yet
because this PR is big enough.
# New way of filtering on date intervals
As we'll progressively rollup Temporal everywhere in the codebase and
remove `Date` JS object everywhere possible, we'll use the way to filter
that is recommended by Temporal.
This way of filtering on date intervals involves half-open intervals,
and is the preferred way to avoid edge-cases with DST and smallest time
increment edge-case.
## Filtering endOfX with DST edge-cases
Some day-light save time shifts involve having no existing hour, or even
day on certain days, for example Samoa Islands have no 30th of December
2011 : https://www.timeanddate.com/news/time/samoa-dateline.html, it
jumps from 29th to 31st, so filtering on `< next period start` makes it
easier to let the date library handle the strict inferior comparison,
than filtering on `≤ end of period` and trying to compute manually the
end of the period.
For example for Samoa Islands, is end of day `2011-12-29T23:59:59.999`
or is it `2011-12-30T23:59:59.999` ? If you say I don't need to know and
compute it, because I want everything strictly before
`2011-12-29T00:00:00 + start of next day (according to the library which
knows those edge-cases)`, then you have a 100% deterministic way of
computing date intervals in any timezone, for any day of any year.
Of course the Samoa example is an extreme one, but more common ones
involve DST shifts of 1 hour, which are still problematic on certain
days of the year.
## Computing the exact _end of period_
Having an open interval filtering, with `[included - included]` instead
of half-open `[included - excluded)`, forces to compute the open end of
an interval, which often involves taking an arbitrary unit like minute,
second, microsecond or nanosecond, which will lead to edge-case of
unhandled values.
For example, let's say my code computes endOfDay by setting the time to
`23:59:59.999`, if another library, API, or anything else, ends up
giving me a date-time with another time precision `23:59:59.999999999`
(down to the nanosecond), then this date-time will be filtered out,
while it should not.
The good deterministic way to avoid 100% of those complex bugs is to
create a half-open filter :
`≥ start of period` to `< start of next period`
For example :
`≥ 2025-01-01T00:00:00` to `< 2025-01-02T00:00:00` instead of `≥
2025-01-01T00:00:00` to `≤ 2025-01-01T23:59:59.999`
Because, `2025-01-01T00:00:00` = `2025-01-01T00:00:00.000` =
`2025-01-01T00:00:00.000000` = `2025-01-01T00:00:00.000000000` => no
risk of error in computing start of period
But `2025-01-01T23:59:59` ≠ `2025-01-01T23:59:59.999` ≠
`2025-01-01T23:59:59.999999` ≠ `2025-01-01T23:59:59.999999999` =>
existing risk of error in computing end of period
This is why an half-open interval has no risk of error in computing a
date-time interval filter.
Here is a link to this debate :
https://github.com/tc39/proposal-temporal/issues/2568
> For this reason, we recommend not calculating the exact nanosecond at
the end of the day if it's not absolutely necessary. For example, if
it's needed for <= comparisons, we recommend just changing the
comparison code. So instead of <= zdtEndOfDay your code could be <
zdtStartOfNextDay which is easier to calculate and not subject to the
issue of not knowing which unit is the right one.

Temporal
## Application to our codebase
Applying this half-open filtering paradigm to our codebase means we
would have to rename `IS_AFTER` to `IS_AFTER_OR_EQUAL` and to keep
`IS_BEFORE` (or even `IS_STRICTLY_BEFORE`) to make this half-open
interval self-explanatory everywhere in the codebase, this will avoid
any confusion.
See the relevant issue :
https://github.com/twentyhq/core-team-issues/issues/2010
In the mean time, we'll keep this operand and add this semantic in the
naming everywhere possible.
## Example with a different user timezone
Example on a graph grouped by week in timezone Pacific/Samoa, on a
computer running on Europe/Paris :
<img width="342" height="511" alt="image"
src="https://github.com/user-attachments/assets/9e7d5121-ecc4-4233-835b-f59293fbd8c8"
/>
Then the associated data in the table view, with our **half-open
date-time filter** :
<img width="804" height="262" alt="image"
src="https://github.com/user-attachments/assets/28efe1d7-d2fc-4aec-b521-bada7f980447"
/>
And the associated SQL query result to see how DATE_TRUNC in Postgres
applies its internal start of week logic :
<img width="709" height="220" alt="image"
src="https://github.com/user-attachments/assets/4d0542e1-eaae-4b4b-afa9-5005f48ffdca"
/>
The associated SQL query without parameters to test in your SQL client :
```SQL
SELECT "opportunity"."closeDate" as "close_date", TO_CHAR(DATE_TRUNC('week', "opportunity"."closeDate", 'Pacific/Samoa') AT TIME ZONE 'Pacific/Samoa', 'YYYY-MM-DD') AS "DATE_TRUNC by week start in timezone Pacific/Samoa", "opportunity"."name" FROM "workspace_1wgvd1injqtife6y4rvfbu3h5"."opportunity" "opportunity" ORDER BY "opportunity"."closeDate" ASC NULLS LAST
```
# Date picker simplification (not in this PR)
Our DatePicker component, which is wrapping `react-datepicker` library
component, is now exposing plain dates as string instead of Date object.
The Date object is still used internally to manage the library
component, but since the date picker calendar is only manipulating plain
dates, there is no need to add timezone management to it, and no need to
expose a handleChange with Date object.
The timezone management relies on date time inputs now.
The modification has been made in a previous PR :
https://github.com/twentyhq/twenty/issues/15377 but it's good to
reference it here.
# Calendar feature refactor
Calendar feature has been refactored to rely on Temporal.PlainDate as
much as possible, while leaving some date-fns utils to avoid re-coding
them.
Since the trick is to use utils to convert back and from Date object in
exec env reliably, we can do it everywhere we need to interface legacy
Date object utils and Temporal related code.
## TimeZone is now shown on Calendar :
<img width="894" height="958" alt="image"
src="https://github.com/user-attachments/assets/231f8107-fad6-4786-b532-456692c20f1d"
/>
## Month picker has been refactored
<img width="503" height="266" alt="image"
src="https://github.com/user-attachments/assets/cb90bc34-6c4d-436d-93bc-4b6fb00de7f5"
/>
Since the days weren't useful, the picker has been refactored to remove
the days.
# Miscellaneous
- Fixed a bug with drag and drop edge-case with 2 items in a list.
# Improvements
## Lots of chained operations
It would be nice to create small utils to avoid repeated chained
operations, but that is how Temporal is designed, a very small set of
primitive operations that allow to compose everything needed. Maybe
we'll have wrappers on top of Temporal in the coming years.
## Creation of Temporal objects is throwing errors
If the input is badly formatted Temporal will throw, we might want to
adopt a global strategy to avoid that.
Example :
```ts
const newPlainDate = Temporal.PlainDate.from('bad-string'); // Will throw
```
## Fix filter parsing for charts
Fixes https://github.com/twentyhq/twenty/issues/16606
Fixes https://github.com/twentyhq/private-issues/issues/396
When clicking on a chart slice/bar grouped by certain field types, the
filter value was passed as a plain string instead of a JSON array,
causing a JSON parse error on navigation.
This happens because `arrayOfStringsOrVariablesSchema` in the filter
parsing logic expects JSON array format for certain field types, but the
values weren't wrapped correctly for all cases.
Extracted the util `formatChartFilterValue` and renamed it to
`serializeChartBucketValueForFilter` and modified it to handle JSON
array wrapping for:
- CURRENCY fields with currencyCode subfield (IS operand)
- MULTI_SELECT fields (CONTAINS operand)
- ADDRESS fields with addressCountry subfield (CONTAINS operand)
Added unit tests for the new utility
### Before
https://github.com/user-attachments/assets/9a52572b-e896-445a-9f5c-e21963f78441
### After
https://github.com/user-attachments/assets/12eed5e5-a49c-4557-a45c-ac7e00b3422a
- Ability to display the details of a field
- The field can be edited (relations edition will be supported later)
- For now, the widget configuration stores the name of the field instead
of its fieldMetadataId. A hook resolves the fieldMetadataId from the
list of fields and the provided name. This will be replaced once we
migrate the configuration to the backend.
## Demo
https://github.com/user-attachments/assets/ab7efbda-66b2-46c1-b641-c350977c31dd
## Remaining to do
- Edition of relations
## Summary
This PR adds the `lingui/no-unlocalized-strings` ESLint rule to detect
untranslated strings and fixes translation issues across multiple
components.
## Changes
### ESLint Configuration (`eslint.config.react.mjs`)
- Added comprehensive `ignore` patterns for non-translatable strings
(CSS values, HTML attributes, technical identifiers)
- Added `ignoreNames` for props that don't need translation (className,
data-*, aria-*, etc.)
- Added `ignoreFunctions` for console methods, URL APIs, and other
non-user-facing functions
- Disabled rule for debug files, storybook, and test files
### Components Fixed (~19 files)
- Object record components (field inputs, pickers, merge dialogs)
- Settings components (accounts, admin panel)
- Serverless function components
- Record table and title cell components
## Status
🚧 **Work in Progress** - ~124 files remaining to fix
This PR is being submitted as draft to allow progressive fixing of
remaining translation issues.
## Testing
- Run `npx eslint "src/**/*.tsx"` in `packages/twenty-front` to check
remaining issues
We checked for widget types by doing `configuration?.__typename ===
'LineChartConfiguration'` which made the code difficult to read.
In this PR, I introduce type guards for each widget type.
Note: the configuration type is `WidgetConfiguration |
FieldsConfiguration` for now but should be changed to
`WidgetConfiguration` when @Devessier adds FieldsConfiguration to the
backend type `WidgetConfiguration`.
