Composite Resources Possible DSL

[wazery]

I opened this issue to discuss the possible DSL ideas for the Composite Resources feature.

The feature is:

Imagine the case when in user signup form user can enter company name and the company will be automatically created:

class UserWithCompanyForm < ActiveForm::Base
  self.main_model = :user

  attributes :email, :password, :company_name, presence: true

  def save
    if @model.save
      Company.create(owner_id: @model.id, name: company_name)
      true
    else
      false
    end
  end
end

Instead of code above, we could provide some API.

---

I just need to understand the difference between this and the association method, is this for the resources that have no relations to the main model? If so what do you imagine/suggest a good DSL to do so?

I have a very rough suggestion:

class UserWithCompanyForm < ActiveForm::Base
  self.main_model = :user

  attributes :email, :password, :company_name, presence: true

  composite :company do
    owner_id: @model.id
    name: company_name
  end
end

@kirs please if you have any ideas in mind lets discuss them here.

I feel like we're getting to far into DSL land here. I'm much more of a fan of Davids original API sketch: https://gist.github.com/dhh/b0a106a00e8737280666#file-aggregator-rb-L7

To me having a method users can override to setup the relationships themselves feels like the clearer and easier way to go.

What do you guys think?

Alright I'll close this then. Thanks for the input 😄

@kaspth I didn't get why you closed this issue. I liked your suggestion and in search for how to implement it, also I hope to let this issue open for any other suggestions and questions.

Sorry I was under the impression this was specifically about the above DSL sample and not a general discussion.
