Default values

When creating new model, you can specify default values for fields. These values will be used when creating new records if the field is not specified.

src/models/post.ts

import { Model } from '@warlock.js/cascade'

export class Post extends Model {
  /**
   * Collection name
   */
  public static collection = "posts";

  /**
   * {@inheritDoc}
   */
  public defaultValue: Document = {
    isActive: false,
  };

  /**
   * {@inheritDoc}
   */
  protected casts: Casts = {
    title: "string",
    content: "string",
    isActive: "boolean",
  };
}

We can also use callbacks to set default values for each field:

src/models/post.ts

import { Model } from '@warlock.js/cascade'

export class Post extends Model {
  /**
   * Collection name
   */
  public static collection = "posts";

  /**
   * {@inheritDoc}
   */
  public defaultValue: Document = {
    isActive: false,
    views: () => {
      return Math.floor(Math.random() * 1000); // random number between 0 and 1000
    },
  };

  /**
   * {@inheritDoc}
   */
  protected casts: Casts = {
    title: "string",
    content: "string",
    isActive: "boolean",
  };
}
