我有一个评论表,我的用户对一部电影发表评论。一条评论belongs_to :movie
和一部电影has_many :comments
我的问题是,当我创建新评论时,这个字段必须在那里<%= f.text_field :movie_id %>
,如果我删除它,我会得到
No route matches {:action=>"show", :controller=>"movies", :id=>nil}
这是创建新评论的绝对路径http://localhost:3000/movies/:movie_id/comments/new
我已经检查了电影控制器中的动作,但什么也看不到。我也玩过 Comments 控制器中的 create 操作,但仍然没有。
在我看来,拥有这个字段可能会让用户感到非常困惑。有人对此有解决方案吗?
这是我的 *comments_controller.rb*
class CommentsController < ApplicationController
# GET /comments
# GET /comments.json
before_filter :load_movie
before_filter :authenticate_user!, only: [:create,:destroy,:edit,:destroy]
...
# GET /comments/new
# GET /comments/new.json
def new
@movie = Movie.find(params[:movie_id])
@comment = @movie.comments.new
@search = Movie.search(params[:q])
respond_to do |format|
format.html # new.html.erb
format.json { render json: @comment }
end
end
# POST /comments
# POST /comments.json
def create
@comment = Comment.new(params[:comment])
@comment.user_id = current_user.id
@search = Movie.search(params[:q])
respond_to do |format|
if @comment.save
@movie = @comment.movie
format.html { redirect_to movie_path(@movie), notice: "Comment created" }
format.json { render json: @comment, status: :created, location: @comment }
else
format.html { render action: "new" }
format.json { render json: @comment.errors, status: :unprocessable_entity }
end
end
end
private
def load_movie
@movie = Movie.find_by_id(params[:movie_id])
end
end
路线.rb
AppName::Application.routes.draw do
resources :comments
resources :movies do
resources :comments, only: [:create,:destroy,:edit,:destroy,:new]
member do
get 'comments'
end
end
end
*_form.html.erb*
<%= form_for(@comment) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.text_field :subject %>
<%= f.text_area :body %>
<%= f.text_field :movie_id %>
</div>
<div class="form-actions">
<%= f.submit "Sumbit Review" %>

<% end %>
