Adding a selection of existing records from another db table to the current one?

Question

Ruby on Rails

I can't figure out how, in the form of creating an entry in the albums table, you can add options for selecting groups from the corresponding model.

Answer 1

It would be more convenient if you published the code of your view, but if I understand you correctly, then something like this:

= form_for(@album) do |f|
  = f.label :name
  = f.text_field :name

  = f.label :release_year
  = f.number_field :release_year

  = f.label :amount_of_member
  = f.number_field :amount_of_member

  = f.label :band
  = f.collection_select :band_id, Band.all, :id, :name, prompt: 'Select a Band'

The same thing with songs, only you make a selector for albums.
