Search by type on associations fields

[Paul-Bob]

Context

When there are two fields with the same ID, the current implementation does not distinguish between different field types. For example:

def fields
  field :speakers, as: :tags, hide_on: [:show, :forms] do
    record.speakers.map(&:name)
  end

  field :speakers, as: :has_many, through: :speaker_talks
end

When rendering the has_many field in the show view, we should search for fields based on both the ID (speakers) and the association type (has_many) to ensure the correct field is selected.

Since hide_on: [:show, :forms] is present on the tags field it should not even be taken into consideration when searching for fields on the show view.
