Rails 缺少模板错误 (haml)

Question

我试图让它工作，但是当我尝试加载页面时它显示错误，我试图在 posts 下面显示评论。

= render post.comments, post: post

上面那行是导致问题的那一行，因为找不到模板而导致错误，它被称为_comment.html.haml。

.posts-wrapper


.post
  .post-head
    .thumb-img
    .user-name
      = post.user.user_name
  .image.center-block
    = link_to (image_tag post.image.url(:medium), class:'img-responsive'), post_path(post)
  .post-bottom
    .caption
      .caption-content
        .user-name
          = post.user.user_name
        = post.caption
      .comments{id: "comments_#{post.id}"}
        - if post.comments
          = render post.comments, post: post
.comment-like-form.row
  .like-button.col-sm-1
    %span(class="glyphicon glyphicon-heart-empty")
  .comment-form.col-sm-11
    = form_for [post, post.comments.build] do |f|
      = f.text_field :content, placeholder: 'Add a comment...', class: "comment_content", id: "comment_content_#{post.id}"

comment 是 post 内的嵌套路由。

下面是应该渲染的部分文件_comment

    .user-name
    = comment.user.user_name
  .comment-content
    = comment.content
  - if comment.user == current_user
    = link_to post_comment_path(post, comment), method: :delete, data: { confirm: "Are you sure?" }, remote: true do
      %span(class="glyphicon glyphicon-remove delete-comment")

路线：

    Rails.application.routes.draw do
  devise_for :users, :controllers => { registrations: 'registrations' }  

  resources :posts do 
    resources :comments
  end

  root 'posts#index'

end

谢谢

依我看，Rails 找不到您的 _comments 部分内容。我猜你把它放在了不属于它的地方。

您的视图结构应如下所示：

views
  comments
    _comment.html.haml
  posts
    _post.html.haml

_comment.html.haml 必须在评论文件夹中。
