Append data to model JSON

[behnamazimi]

I'm looking for the Laravel append functionality in lucid. I mean I want to add a parameter to fetched JSON like what append did in the Laravel.

I tried the Mutators but there was not the solution! Another way is loops, like "for" or "map" on the fetched data but it's not best practice! Also, the result is different when I work with ORM and when fetch data by Query Builder.

The Query Builder return a valid array of data but ORM return rows! what is that "rows" ?! Does it mean the rows of my model in DB? If so, how should I loop on it?!

Please don't expect me to read the Laravel docs and understand what append does and then code the solution for you.

I understand that AdonisJs is inspired by Laravel, but you guys have to also do some hard work and create actionable issues.

It will be nice, if you can share the current shape of your object and what is the desired shape.

@thetutlage , you right. Let me explain by a real model.

I have a user model and this JSON is the result of a pure query in the AdonisJs and also Laravel.

[
  {
    name: "test user",
    username: "testuser",
    email: "user@example.com"
  },
  {
    name: "test user",
    username: "testuser",
    email: "user@example.com"
  },...
]

I wnat to add a new fake parameter (fake_param) to each item of my result. and after that the result must be like below:

[
  {
    name: "test user",
    username: "testuser",
    email: "user@example.com",
    fake_param: "random str"
  },
  {
    name: "test user",
    username: "testuser",
    email: "user@example.com",
    fake_param: "random str"
  },...
]

How should I do this in the AdonisJs?

In the Laravel, to add a new parameter to the result JSON we use append functionality.

Thanks for your time

I believe, you can get it working (unless is value is computed asynchronously) using computed properties.

class User extends Model {
  static get computed () {
     return ['fake_param']
  }

  getFakeParam () {
     return 'whatever'
  }
}

and then fetching users will append this property.

const users = await User.all()
users.toJSON()

@thetutlage Hi, Can I use get computed conditionally? (For example, append isOwner property if request's userId is equal to object's userId?
