Question

我的应用程序中有一个form_for正在提交错误的网址。

          <% @posts.each do |post| %>
          <form class="col-md-12">
            <% comment = post.comments.build %>
            <%= form_for [post, comment], :url => post_comments_path(post), html: {class: "col-md-12", method: "POST"} do |comment_fields| %>
              <div class="form-group">
                <%= comment_fields.text_area :content, placeholder: "Write a comment...", class: "form-control", rows: "4" %>
              </div>
              <div class="form-group">
                <a class="col-md-1" href="#">Cancel</a>
                <%= comment_fields.submit "Comment", class: "col-md-3 pull-right btn btn-primary" %>
              </div>
            <% end %>
            <% end %>

这是我的PostsController索引方法：

def index
    @user = User.find(params[:user_id])

    @posts = @user.posts

end

我希望它能转到POST /posts/:post_id/comments(.:format) comments#create

但它正在发送此请求：

Started GET "/users/6/posts?utf8=%E2%9C%93&authenticity_token=WgbO5FhAA0ZhXFdk%2FizEbqTVxg2HW9VDY7aUKQTLmy3qLXLC8EH9%2FKr0w53TcId2KYoJmU7uodCFJOIDufno8g%3D%3D&comment%5Bcontent%5D=qqqqqqqqqqqq111&commit=Comment"

以下是我的路线：

                 PUT    /likes/:id(.:format)                   likes#update
                 DELETE /likes/:id(.:format)                   likes#destroy
   post_comments GET    /posts/:post_id/comments(.:format)     comments#index
                 POST   /posts/:post_id/comments(.:format)     comments#create
new_post_comment GET    /posts/:post_id/comments/new(.:format) comments#new
    edit_comment GET    /comments/:id/edit(.:format)           comments#edit
         comment GET    /comments/:id(.:format)                comments#show
                 PATCH  /comments/:id(.:format)                comments#update
                 PUT    /comments/:id(.:format)                comments#update
                 DELETE /comments/:id(.:format)                comments#destroy
      user_posts GET    /users/:user_id/posts(.:format)        posts#index
                 POST   /users/:user_id/posts(.:format)        posts#create

有没有办法用form_for做到这一点？我可以使用form_tag post_likes_path，使用方法：delete选项，但我想自动将@ comment.post_id设置为帖子。

请勿将form保留在另一个form内。试试这个：

<% @posts.each do |post| %>
  <div class="col-md-12">
    <% comment = post.comments.build %>
    <%= form_for [post, comment], :url => post_comments_path(post), html: {class: "col-md-12"} do |comment_fields| %>
          <div class="form-group">
            <%= comment_fields.text_area :content, placeholder: "Write a comment...", class: "form-control", rows: "4" %>
          </div>
          <div class="form-group">
            <a class="col-md-1" href="#">Cancel</a>
            <%= comment_fields.submit "Comment", class: "col-md-3 pull-right btn btn-primary" %>
          </div>
    <% end %>
 </div>
<% end %>

我的form_for [post，comment]正在提交错误的网址？
