У меня есть три модели:Rails 4: ActionController :: UrlGenerationError
class User < ActiveRecord::Base
has_many :administrations
has_many :calendars, through: :administrations
end
class Calendar < ActiveRecord::Base
has_many :administrations
has_many :users, through: :administrations
end
class Administration < ActiveRecord::Base
belongs_to :user
belongs_to :calendar
end
А вот мои маршруты:
resources :users do
resources :administrations
resources :calendars
end
-----------
ОБНОВЛЕНИЕ:
Вот что я получаю, когда я запускаю rake routes в Терминале:

UPDATE 2:
Вот мой calendars_controller.rb файл:
class CalendarsController < ApplicationController
before_action :set_calendar, only: [:show, :edit, :update, :destroy]
# GET /calendars
# GET /calendars.json
def index
@calendars = Calendar.all
end
# GET /calendars/1
# GET /calendars/1.json
def show
end
# GET /calendars/new
def new
@user = User.find(params[:user_id])
@calendar = @user.calendars.new
end
# GET /calendars/1/edit
def edit
@user = User.find(params[:user_id])
@calendar = @user.calendar.find(params[:calendar_id])
end
# POST /calendars
# POST /calendars.json
def create
@user = User.find(params[:user_id])
@calendar = @user.calendars.new(calendar_params)
respond_to do |format|
if @calendar.save
format.html { redirect_to user_calendar_path(@user,@calendar), notice: 'Calendar was successfully created.' }
format.json { render :show, status: :created, location: @calendar }
else
format.html { render :new }
format.json { render json: @calendar.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /calendars/1
# PATCH/PUT /calendars/1.json
def update
respond_to do |format|
if @calendar.update(calendar_params)
format.html { redirect_to @calendar, notice: 'Calendar was successfully updated.' }
format.json { render :show, status: :ok, location: @calendar }
else
format.html { render :edit }
format.json { render json: @calendar.errors, status: :unprocessable_entity }
end
end
end
# DELETE /calendars/1
# DELETE /calendars/1.json
def destroy
@calendar.destroy
respond_to do |format|
format.html { redirect_to calendars_url, notice: 'Calendar was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_calendar
@calendar = Calendar.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def calendar_params
params.require(:calendar).permit(:name)
end
end

http://localhost:3000/users/1/calendars/new и http://localhost:3000/users/1/calendars/1 работа хорошо.
Но всякий раз, когда я пытаюсь получить доступ к http://localhost:3000/users/1/calendars, я получаю следующее сообщение об ошибке:
ActionController::UrlGenerationError in Calendars#index
Showing /Users/TXC/code/rails/calendy/app/views/calendars/index.html.erb where line #17 raised:
No route matches {:action=>"show", :controller=>"calendars", :id=>nil, :user_id=>nil} missing required keys: [:id, :user_id]
Extracted source (around line #17):
<tr>
<td><%= calendar.name %></td>
<td><%= link_to 'Show', user_calendar_path(@user, @calendar) %></td>
<td><%= link_to 'Edit', edit_user_calendar_path(@user, @calendar) %></td>
<td><%= link_to 'Destroy', calendar, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
В частности, я не понимаю missing required keys: [:id, :user_id] части, так как у меня есть и @user и @calendar в моем user_calendar_path.
Очевидно, что чего-то не хватает, но я не могу понять, что.
Любая идея?
пост calendars_controller код пожалуйста –
Конечно, просто сделал это. –
