Default values in Models properties totally being ignored when using migrateschema.

[tarangill]

Steps to reproduce

This is my model:

import {Entity, model, property} from '@loopback/repository';

@model({
  settings: {
  }
})
export class Sound extends Entity {

  @property({
    type: 'string',
    id: true,
    required: true,
    length: 17,
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength":17,
       "nullable":"N"
    }
  })
  sound_id: string;

  @property({
    type: 'string',
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength": 256,
       "nullable":"y",
       default: "heelloi"
    },
  })
  title?: string;

  @property({
    type: 'string',
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength": 1024,
       "nullable":"n"
    }
  })
  url: string;

  @property({
    postgresql: {
      dataType: 'TIMESTAMP WITH TIME ZONE',
      default: 'CURRENT_TIMESTAMP'
    },
    "index": true
  })
  created_at: string;

  constructor(data?: Partial<Sound>) {
    super(data);
  }
}

export interface SoundRelations {
  // describe navigational properties here
}

export type SoundtWithRelations = Sound & SoundRelations;

Current Behavior

When I use app.migrateSchema(['Sound') to automatically create the table, this is what I get from \d+ sound in ysqlsh:

                                              Table "public.sound"
   Column   |           Type           | Collation | Nullable | Default | Storage  | Stats target | Description 
------------+--------------------------+-----------+----------+---------+----------+--------------+-------------
 sound_id   | character varying(17)    |           | not null |         | extended |              | 
 title      | character varying(256)   |           |          |         | extended |              | 
 url        | character varying(1024)  |           |          |         | extended |              | 
 created_at | timestamp with time zone |           |          |         | plain    |              | 
Indexes:
    "sound_pkey" PRIMARY KEY, lsm (sound_id HASH)
    "sound_created_at_idx" lsm (created_at HASH)

Notice how there is no default values for title and created at?

this is the output of the npm start run with DEBUG=loopback:connector:*:

Expected Behavior

The created tables should have default values.

Ok, I found a fix. I don't think this is documented anywhere, but with postgresql, you have to use dbDefault, not default. So changing my model to the following fixed the issue:

import {Entity, model, property} from '@loopback/repository';

@model({
  settings: {
  }
})
export class Sound extends Entity {

  @property({
    type: 'string',
    id: true,
    required: true,
    length: 17,
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength":17,
       "nullable":"N"
    }
  })
  sound_id: string;

  @property({
    type: 'string',
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength": 256,
       "nullable":"y",
       dbDefault: "'heelloi'"
    },
  })
  title?: string;

  @property({
    type: 'string',
    postgresql:
    {
       "dataType":"VARCHAR",
       "dataLength": 1024,
       "nullable":"n"
    }
  })
  url: string;

  @property({
    postgresql: {
      dataType: 'TIMESTAMP WITH TIME ZONE',
      dbDefault: 'CURRENT_TIMESTAMP'
    },
    "index": true
  })
  created_at: string;

  constructor(data?: Partial<Sound>) {
    super(data);
  }
}

export interface SoundRelations {
  // describe navigational properties here
}

export type SoundtWithRelations = Sound & SoundRelations;
