Public Instance Methods

model(main_model, options={}) click to toggle source

Set a model name for this form if the infered is wrong.

class CoverSongForm < Reform::Form
  model :song

or we can setup a isolated namespace model ( which defined in isolated rails egine )

class CoverSongForm < Reform::Form
  model "api/v1/song", namespace: "api"
# File lib/reform/form/active_model.rb, line 69
def model(main_model, options={})
  self.model_options = [main_model, options]
end
model_name() click to toggle source
# File lib/reform/form/active_model.rb, line 73
def model_name
  if model_options
    form_name = model_options.first.to_s.camelize
    namespace = model_options.last[:namespace].present? ? model_options.last[:namespace].to_s.camelize.constantize : nil
  else
    if name
      form_name = name.sub(/(::)?Form$/, "") # Song::Form => "Song"
      namespace = nil
    else # anonymous forms. let's drop AM and forget about all this.
      form_name = "reform"
      namespace = nil
    end
  end

  active_model_name_for(form_name, namespace)
end
name() click to toggle source

this adds Form::name for AM::Validations and I18N.

# File lib/reform/form/active_model.rb, line 36
def name
  @_name
end
property(*) click to toggle source

DISCUSS: can we achieve that somehow via features in build_inline?

      # this adds Form::name for AM::Validations and I18N.
