Question

我的Rails应用程序有很大的问题。我为我的功课创建了高级博客

我需要编辑我的评论，但我的网址返回此'/ posts / 4％2F12 / comments / 4 / edit'而不是/ posts / 4 / comments / 12 / edit

如果我自己正确输入URL，则可以访问有效的修改表单

您可以在这里看到我的代码

show.html.haml

.article
  .container
    .row
      .col-lg-12
        .cover-image{:style => "background-image: url('#{@post.photo_url}');"}
        %h1.mt-4= @post.title

        #{I18n.l(@post.created_at)}
        %hr/

        %p.lead= @post.content.html_safe
        %hr/

        .card.my-4
          %h5.card-header Ajouter un commentaire :
          .card-body
            = render 'comments/form', comment: @post.comments.build

        .media.mb-4
          .media-body
            - @post.comments.each do |comment|
              %h5.mt-0= comment.content
              %h5.mt-0= comment.user_name
              %h2 Edit user
              = link_to edit_post_comment_path([@post, comment]) do
                %button.btn.btn-primary{:type => "button"} Primary
              = link_to "Delete Comment", [@post, comment], method: :delete, data: { confirm: 'Are you sure?' }

comments_controller.rb

before_action :set_post, only: [:create]

def create
  @comment = @post.comments.new(comment_params)
  @comment.user_name = current_user.nickname
  if @comment.save!
    redirect_to @post
  else
    flash.now[:danger] = "error"
  end
end

def edit
  @post = Post.find(params[:post_id])
end


def destroy
  @post = Post.find(params[:post_id])
  @comment = @post.comments.find(params[:id])
  @comment.destroy
  redirect_to post_path(@post)
 end


private

def comment_params
  params[:comment].permit(:content, :post_id)
end

def post_params
  params.require(:comment).permit(:content)
end

def set_post
  @post = Post.find(params[:post_id])
end

routes.rb

  resources :users, only: :show

  resources :posts do
    resources :comments
  end

  root 'home#index'

  root :to => redirect("/users/sign_in")

Answer 1

您应该将两个参数传递给edit_post_comment_path方法，而不是像这样传递数组：

edit_post_comment_path(@post, comment)

Answer 2

代替

link_to edit_post_comment_path([@post, comment]) do

尝试

link_to edit_post_comment_path(@post, comment) do

或者

link_to [:edit, @post, comment] do

请参见https://guides.rubyonrails.org/routing.html#creating-paths-and-urls-from-objects

Answer 3

也在Comments Controller 中使用before_action进行评论

before_action :set_comment, only: [:show, :edit, :update, :destroy]
.....
.....

private

def set_comment
  @comment = @post.comments.find(params[:id])
end

，然后在views / comments / show.html.haml

edit_post_comment_path(@post, @comment)

尝试一下...

Rails的编辑路径无法获得正确的URL
