Create a new field — Field — Content Management API

appearance Optional object Example: {"editor":"single_line","parameters":{"heading":false},"addons":[{"id":"1234","field_extension":"lorem_ipsum","parameters":{}}]}

Field appearance details, plugin configuration and field add-ons

position Optional integer Example: 1

Ordering index

hint Optional string, null Example: "This field will be used as post title"

Field hint

default_value Optional boolean, null, string, number, object Example: {"en":"A default value","it":"Un valore di default"}

Default value for Field. When field is localized accepts an object of default values with site locales as keys

deep_filtering_enabled Optional boolean Example: true

Whether deep filtering for block models is enabled in GraphQL or not

fieldset Optional null, { type: "fieldset", id: fieldset.id }

Fieldset linkage

Returns

Returns a field resource object.

Examples

Example Basic example

This is a complete example for creating a new localized Single-line string field:

import { buildClient } from '@datocms/cma-client-node';
async function run() {
  const client = buildClient({ apiToken: '<YOUR_API_TOKEN>' });
  
  const modelIdOrApiKey = 'blog_post';
  
  const field = await client.fields.create(modelIdOrApiKey, {
    label: 'Title',
    field_type: 'string',
    api_key: 'title'
  });
  
  console.log(field);
}
run();

Example Creating Modular Content fields

In this example:

first we create some block models using the client.itemTypes.create() method, making sure to set the modular_block attribute to true — this tells the API that they're in fact block models, and not regular models;
we then create a Modular content field, passing down the allowed block models in the rich_text_blocks validator:

import { buildClient } from "@datocms/cma-client-node";
async function run() {
  // Make sure the API token has access to the CMA, and is stored securely
  const client = buildClient({ apiToken: process.env.DATOCMS_API_TOKEN });
  const modularBlock1 = await client.itemTypes.create({
    name: "Modular Block 1",
    api_key: "modular_block1",
    modular_block: true,
  });
  const modularBlock2 = await client.itemTypes.create({
    name: "Modular Block 2",
    api_key: "modular_block2",
    modular_block: true,
  });
  const itemTypeId = "1234";
  const field = await client.fields.create(itemTypeId, {
    label: "Content",
    field_type: "rich_text",
    api_key: "content",
    validators: {
      rich_text_blocks: {
        item_types: [modularBlock1.id, modularBlock2.id],
      },
    },
  });
  console.log(field);
}
run();

Example Creating Structured Text fields

Structured Text fields support both embedded block records and links to other regular records.

For DatoCMS, a block model is just like a regular model, so we'll create them with client.itemTypes.create(), passing the modularBlock property to true:

In this example:

first we create some block models using the client.itemTypes.create() method, making sure to set the modular_block attribute to true — this tells the API that they're in fact block models, and not regular models;
we then create the Structured Text field, passing down the embeddable block models in the structured_text_blocks validator, and the linkable record models in the structured_text_links validator:

import { buildClient } from "@datocms/cma-client-node";
async function run() {
  // Make sure the API token has access to the CMA, and is stored securely
  const client = buildClient({ apiToken: process.env.DATOCMS_API_TOKEN });
  const modularBlock1 = await client.itemTypes.create({
    name: "Modular Block 1",
    api_key: "modular_block1",
    modular_block: true,
  });
  const modularBlock2 = await client.itemTypes.create({
    name: "Modular Block 2",
    api_key: "modular_block2",
    modular_block: true,
  });
  const itemTypeId = "1234";
  const field = await client.fields.create(itemTypeId, {
    label: "Structured content",
    field_type: "structured_text",
    api_key: "content",
    validators: {
      structured_text_blocks: {
        item_types: [modularBlock1.id, modularBlock2.id],
      },
      structured_text_links: {
        item_types: [itemTypeId],
      },
    },
  });
  console.log(field);
}
run();
