How to produce static getter for a class property?

[c5n8]

Like this

class User extends Model {
  static get table () {
    return 'my_users'
  }
}

We treat getters and setters as a discouraged practice. See http://coffeescript.org/#unsupported-get-set. That said, it’s possible to create a getter for a class using the verbose syntax, and such a getter is automatically available statically:

class User extends Model

Object.defineProperty User, 'table', {get: -> 'my_users'}

User.table  # 'my_users'

Ok, thanks, I'll try it. I appreciate your awesome works on coffeescript.
Anyway, what is your argument against getters and setters?

[GeoffreyBooth]

See http://coffeescript.org/#unsupported-get-set and #4484.

Sorry to bother again, but I cannot produce this

class User extends Model {
  static get dates () {
    return super.dates.concat(['dob'])
  }
}

Any idea?

[c5n8]

Anyway, I still cant implement your previous example, and I end up set it as property like this

class User extends Model
  @hidden = [ 'password' ]

[GeoffreyBooth]

Getters and setters are a discouraged practice in JavaScript. Instead I would advise:

class User extends Model
  @getDates: ->
    super.dates.concat ['dob']

which becomes:

User = class User extends Model {
  static getDates() {
    return super.dates.concat(['dob']);
  }
};

and call it via User.getDates() rather than User.dates.

[c5n8]

This is what I use in the end:

class User extends Model
  @dates: @getDates()

  @getDates: -> super.dates.concat(['period'])

The thing is it is required by framework I use, so I have no other choice.
I hope there will be better interoperability with existing js lib, regardless what practice they use.

You can create getters and setters using the verbose syntax, as shown in the docs: http://coffeescript.org/#unsupported-get-set.

class Model
  @dates: ['era']
  
class User extends Model
  @getDates: -> super.dates.concat(['period'])

Object.defineProperty User, 'dates',
  get: -> @getDates()
  
alert User.dates # era,period

What framework are you using that “requires” getters and setters?

[c5n8]

Yeah, that works too, thanks.
It is Adonis Framework.
