martmull 3a9f405e6c docs(apps): document missing enum values and complete entity references (#22691)
Part 4 of the app-docs audit series (after #22688, #22689, #22690).
Focus: values that exist in the SDK but never made it into the docs. All
value lists were extracted from `twenty-shared` / `twenty-sdk` source.

## What this adds/fixes

**data/objects.mdx**
- New "Field types" section with the complete `FieldType` value set (24
values, grouped by category, with the composite/`SELECT` caveats and the
lowercase `universalSettings.dataType` values for `NUMBER`). Previously
no page listed the available field types — readers had to
reverse-engineer them from scattered examples.

**layout/views.mdx**
- `ViewFilterOperand` was imported from `twenty-shared/types` in the
example; it's re-exported from `twenty-sdk/define`, which is the
supported import surface for apps.
- New "Optional properties" table covering what the page omitted: `type`
(`ViewType.TABLE`/`KANBAN`/`CALENDAR`), `visibility`, `openRecordIn`,
`sorts`, kanban aggregate settings, and calendar settings.

**getting-started/scaffolding.mdx**
- The `dev:add` table listed 10 of 14 entity types; added
`pageLayoutTab`, `commandMenuItem`, `viewField`, and
`connectionProvider` (paths follow the CLI's kebab-case convention).

**layout/navigation-menu-items.mdx**
- Note about `NavigationMenuItemType.RECORD`: it exists in the enum but
is internal (user favorites) and has no manifest field to reference a
record, so apps can't use it — documented to prevent confusion about the
"missing" value.

Only English sources were touched; `l/<locale>` copies come from
Crowdin.

title: Scaffolding
description: Generate entity files interactively with yarn twenty dev:add — objects, fields, views, logic functions, and more.
icon: "wand-magic-sparkles"
---
Instead of creating entity files by hand, use the interactive scaffolder:
```bash filename="Terminal"
yarn twenty dev:add
```
It prompts you to pick an entity type and walks you through the required fields, then writes a ready-to-use file with a stable `universalIdentifier` and the correct `defineEntity()` call.
You can also pass the entity type directly to skip the first prompt:
```bash filename="Terminal"
yarn twenty dev:add object
yarn twenty dev:add logicFunction
yarn twenty dev:add frontComponent
```
## Available entity types
| Entity type | Command | Generated file |
|-------------|---------|----------------|
| Object | `yarn twenty dev:add object` | `src/objects/<name>.ts` |
| Field | `yarn twenty dev:add field` | `src/fields/<name>.ts` |
| Logic function | `yarn twenty dev:add logicFunction` | `src/logic-functions/<name>.ts` |
| Front component | `yarn twenty dev:add frontComponent` | `src/front-components/<name>.tsx` |
| Role | `yarn twenty dev:add role` | `src/roles/<name>.ts` |
| Skill | `yarn twenty dev:add skill` | `src/skills/<name>.ts` |
| Agent | `yarn twenty dev:add agent` | `src/agents/<name>.ts` |
| View | `yarn twenty dev:add view` | `src/views/<name>.ts` |
| Navigation menu item | `yarn twenty dev:add navigationMenuItem` | `src/navigation-menu-items/<name>.ts` |
| Page layout | `yarn twenty dev:add pageLayout` | `src/page-layouts/<name>.ts` |
| Page layout tab | `yarn twenty dev:add pageLayoutTab` | `src/page-layout-tabs/<name>.ts` |
| Command menu item | `yarn twenty dev:add commandMenuItem` | `src/command-menu-items/<name>.ts` |
| View field | `yarn twenty dev:add viewField` | `src/view-fields/<name>.ts` |
| Connection provider | `yarn twenty dev:add connectionProvider` | `src/connection-providers/<name>.ts` |
## What the scaffolder generates
Each entity type has its own template. For example, `yarn twenty dev:add object` asks for:
1. **Name (singular)** — e.g., `invoice`
2. **Name (plural)** — e.g., `invoices`
3. **Label (singular)** — auto-populated from the name (e.g., `Invoice`)
4. **Label (plural)** — auto-populated (e.g., `Invoices`)
5. **Create a view and navigation item?** — if you answer yes, the scaffolder also generates a matching view and sidebar link for the new object.
Other entity types have simpler prompts — most only ask for a name.
The `field` entity type is more detailed: it asks for the field name, label, type (from a list of all available field types like `TEXT`, `NUMBER`, `SELECT`, `RELATION`, etc.), and the target object's `universalIdentifier`.
## Custom output path
Use the `--path` flag to place the generated file in a custom location:
```bash filename="Terminal"
yarn twenty dev:add logicFunction --path src/custom-folder
```
