Question

我正在使用ancestry gem在我的帖子中创建嵌套评论。

我使用Rails 5。

这是我的代码：

发布模型

has_many :comments

评论模型

  has_ancestry
  belongs_to :post

我在视图/帖子/节目中呈现所有评论

<%= render 'comment' %>

内部视图/评论/ _评论

<%= div_for(comment) do %>
  <%= comment.body %>
  <%= link_to "Reply", new_post_comment_path(:parent_id => comment, :post_id => @post.id) %>
<% end %>

comments_controller

  def create
    @comment = @post.comments.new(comment_params)
    @comment.user = current_user

    respond_to do |format|
      if @comment.save
        format.html { redirect_to @post, notice: 'Comment was successfully 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

  def new
    @comment = Comment.new(:parent_id => params[:parent_id])
  end

评论表

<%= simple_form_for new_post_comment_path(@post,@comment)  do |f| %>
    <%= f.hidden_field :parent_id %>
    <%= f.text_area :body, class: "form-control" %>
    <%= f.submit "Leave Comment", class: 'btn btn-main btn-block'  %>
<% end %>

Routes.rb

resources :posts do
    resources :comments
end

耙路

           post_comments GET      /:post_id/comments(.:format)            comments#index
                         POST     /:post_id/comments(.:format)            comments#create
        new_post_comment GET      /:post_id/comments/new(.:format)        comments#new
       edit_post_comment GET      /:post_id/comments/:id/edit(.:format)   comments#edit
            post_comment GET      /:post_id/comments/:id(.:format)        comments#show
                         PATCH    /:post_id/comments/:id(.:format)        comments#update
                         PUT      /:post_id/comments/:id(.:format)        comments#update
                         DELETE   /:post_id/comments/:id(.:format)        comments#destroy

在此URL http://localhost:3000/post_id/comments/new?parent_id=10中，我点击了“回复评论”，它呈现了新的评论表格。但是，如果我单击“提交”按钮，则会出现此错误

没有路线匹配[POST]“ / post_id / comments / new”

请有人帮我解决。谢谢

忘记我的评论。我混合了一些东西。

您的问题在

评论，：post_id => @ post.id）％>

new_post_comment_path解析为/:post_id/comments/new(.:format) comments#new，由于其GET路径并且没有POST，因此它不起作用。您必须发布到/:post_id/comments(.:format)

因为我可以在本地尝试，所以您可以尝试

<%= link_to "Reply", post_comment_path(:parent_id => comment, :post_id => @post.id), method: :post %>

或手动添加正确的路径，例如

link_to 'foo', :action => :foo, :id => @bar.id, method: :post

或

link_to 'foo', '/foo/#{@bar.id}', method: :post
