Question

I’ve got an embedded resource inside of a singular resource (/profile/workout) and am having some problems with the form_for helper.

I’ve defined the following helper, since profile is just based off the current_user (just redirects to the right url):

def workout_path(*args)
    profile_workout_path(*args)
end

I’ve got the following model:

class Workout
  include Mongoid::Document
  include Mongoid::Timestamps

  field :name, type: String

  embedded_in :user
  embeds_many :movements
  accepts_nested_attributes_for :movements
end

controller:

def new
  @workout = current_user.workouts.build
  @workout.movements.build
end

routes:

ComposerDelete::Application.routes.draw do
  authenticated :user do
    root :to => 'home#index'
  end

  root :to => "home#index"
  devise_for :users
  resources :users do
  end

  resource :profile do
    resources :workouts
  end
end

and form

= form_for @workout do |f|
  %fieldset
    = f.label :name
    = f.text_field :name
    = f.fields_for :movements do |builder|
      = render "movement_fields", f: builder
    = link_to_add_fields "Add Movement", f, :movements
    = f.submit "Create"

When I visit the url: http://localhost:3500/profile/workouts/50b99b70f0f800cd53000002/edit, the form has the following header:

<form accept-charset="UTF-8" action="/profile/workouts/50b99b70f0f800cd53000002" class="edit_workout" id="edit_workout_50b99b70f0f800cd53000002" method="post">

It gets the right id (edit_<model>_<id>), but the wrong method (post, should be put), also, the submit button says Create instead of Update. The form works correctly, and updates the workout.

rake routes:

                    root        /                                    home#index
                    root        /                                    home#index

The method will always be POST, not PUT – your browser does not support PUT natively, so Rails hacks around this by using a hidden form field inside the form with _method=PUT. See here for some documentation on this.

also, your own code says = f.submit "Create" so it’s no wonder the button says ‘Create’.
