# edit-column

Change one column of a Data Table. Supply at least one property to change; only the properties you supply change. Needs the `fabric:table.write` grant.

**Edit a column**

const fabric = new Fabric()
const result = await fabric.editColumn({
  table_id: '6ab196817566f41b5c28e31f',
  column_id: '6ab1968193a7cbd766d5cd74',
  column_name: 'notes_renamed'
})
```

```ts
// result is the payload itself, with no `.result` to read
{
  table_id: '6ab196817566f41b5c28e31f',
  column: {
    column_id: '6ab1968193a7cbd766d5cd74',

```

**Python SDK**

```python
from wexa import Fabric

fabric = Fabric()
out = fabric.edit_column(
    table_id="6ab196817566f41b5c28e31f",
    column_id="6ab1968193a7cbd766d5cd74",
    column_name="notes_renamed",
)
```

```python
# out is the result, already unwrapped
{
    "table_id": "6ab196817566f41b5c28e31f",
    "column": {
        "column_id": "6ab1968193a7cbd766d5cd74",

## Parameters

| Parameter | Type | Required | Notes |
| --- | --- | --- | --- |
| `table_id` | string | Required | Table id from `list-tables`, a 24-character hex id. A table in this project. |
| `column_id` | string | Required | Column id from `get-table`. A column on that table. |
| `column_name` | string | Optional | New name. |
| `column_type` | string | Optional | New type. |
| `array_type` | string | Optional | Item type, for an Array column. |
| `default_value` | any | Optional | Default value for the column. |
| `enum_options` | array | Optional | Allowed values, for an Enum column. |

**Errors**

- `ValidationError` (400 / 422): no property to change was supplied. Pass at least one of `column_name`, `column_type`, `array_type`, `default_value` or `enum_options`.

**TypeScript SDK**

```ts
// the object you get back IS the result — there is no `.result` to read
{
  column: {
    array_type: null,
    column_id: '6ab1968193a7cbd766d5cd74',
    column_name: 'notes_renamed',
    column_type: 'String',
    default_value: null,

    object_fields: null
  },
  table_id: '6ab196817566f41b5c28e31f',
  triggers_preserved: 0
}

// The TS SDK names these camelCase — lifecycleId, traceId — where Python uses
// lifecycle_id and trace_id. Both are non-enumerable: readable, but omitted by
// Object.keys() and JSON.stringify(). `result.lifecycleId` here is undefined.
result.lifecycleId // 'qlc_000204'
```

**Python SDK**

```python
# a dict subclass; `result` is already unwrapped
{
 "column": {
  "array_type": None,
  "column_id": "6ab1968193a7cbd766d5cd74",
  "column_name": "notes_renamed",
  "column_type": "String",
  "default_value": None,
  "enum_options": None,
  "has_triggers": False,
  "object_fields": None
 },
 "table_id": "6ab196817566f41b5c28e31f",
 "triggers_preserved": 0
}

out.lifecycle_id  # 'qlc_000204' — an attribute, not a key
```

**More details**

The column is read back first and its triggers are written with it, so editing a column never disables its automation. The result reports `triggers_preserved`.

`edit-column` changes a table but is not marked consequential: it is audited lightly and the project's write gate never holds it.
