Understanding the `_config` Endpoint

The _config endpoint is a crucial component of your application's API, playing a vital role in rendering tables on the frontend. In this article, we will delve into the details of the _config endpoint, exploring its purpose, request structure, and response format.

Endpoint Details

Method: POST

URL: `{model_view_name}/_config`

Description:

The _config endpoint returns the configuration required for the frontend to render a table. It specifies which columns to display and what filters are available.

Request Example

To access the _config endpoint, you can send a POST request to the specified URL. The payload is empty, as shown below:

POST: `/lcs/sub_asset_type/_config`
Payload: {}

Response Example

The response from the _config endpoint varies depending on whether the user has provided a default view or not. We will explore both scenarios below.

When User Has Not Provided the Default View

In this case, the response will contain the default configuration for the table. The response will have the following structure:

{
    "success": true,
    "data": {
        "name": "sub_asset_type_default_view",
        "label": "Sub Asset Type Default View",
        "type": "view",
        "model": "sub_asset_type",
        "attributes": {
            "uuid": {
                "type": "uuid",
                "label": "ID"
            },
            "name": {
                "type": "string",
                "label": "Name"
            },
            "slug": {
                "type": "string",
                "label": "Slug"
            },
            "asset_type_uuid": {
                "type": "string",
                "label": "Asset Type ID"
            },
            "created_at": {
                "type": "timestamp",
                "label": "Created At"
            },
            "updated_at": {
                "type": "timestamp",
                "label": "Updated At"
            },
            "deleted_at": {
                "type": "timestamp",
                "label": "Deleted At"
            },
            "asset_type_name": {
                "type": "string",
                "label": "Asset Type Name"
            }
        },
        "lensSimpleFilters": []
    },
    "meta": []
}

When User Has Provided the Default View

If the user has provided a default view, the response will contain the custom configuration for the table. The response will have the following structure:

{
    "success": true,
    "data": {
        "name": "sub_asset_type_default_view",
        "label": "Sub Asset Types Default View",
        "type": "view",
        "model": "sub_asset_type",
        "attributes": {
            "uuid": {
                "type": "uuid",
                "label": "ID"
            },
            "name": {
                "type": "string",
                "label": "Name"
            },
            "asset_type_name": {
                "type": "string",
                "label": "Asset Type Name"
            }
        },
        "lensSimpleFilters": {
            "asset_type_name": {
                "type": "enum",
                "label": "Asset Type Name",
                "model": "asset_type"
            }
        }
    },
    "meta": []
}

Conclusion
