我有一個關於form_for嵌套資源的問題。我創建了一些類似博客的內容,包括文章,評論和評論評論(如回覆)。我有一個問題。然後我試着讓評論的那樣: 「重定向到http://localhost:3000/ 過濾器鏈停止爲:get_parent渲染或重定向 完成302找到」form_for嵌套資源(帖子,評論)
徵求意見new.html.erb:
<div class= "container" %>
<%= form_for @comment do |f| %>
<%= f.input :title %>
<%= f.text_area :body %>
<%= f.submit %>
<% end %>
</div>
我評論控制器:
before_filter :get_parent
def new
@comment = @parent.comments.build
end
def create
@comment = @parent.comments.build(params[:comment])
@comment.user_id = current_user.id
if @comment.save
redirect_to posts_path(@comment.post), :notice => 'Thank you for your comment!'
else
render :new
end
end
private
def comment_params
params.require(:comment).permit(:body, :title, :user_id, :commentable_id, :commentable_type)
end
def get_parent
@parent = Post.find_by_id(params[:post_id]) if params[:post_id]
@parent = Comment.find_by_id(params[:comment_id]) if params[:comment_id]
redirect_to root_path unless defined?(@parent)
end
end
樁模型:
has_many :comments, as: :commentable
belongs_to :user
def post
commentable.is_a?(Post) ? commentable : commentable.post
end
評論型號:
belongs_to :user
belongs_to :commentable, polymorphic: true
has_many :comments, :as => :commentable
路線:
resources :posts do
resources :comments
end
resources :comments do
resources :comments
end
post_show.html.erb
<h1><%= @post.title %></h1>
<div class="body">
<%= @post.body %>
</div>
<h2>Comments</h2>
<p><%= link_to 'Add a Comment', new_post_comment_path(@post) %></p>
<ul class="comment_list">
<%= render :partial => 'comments/comment', :collection => @post.comments %>
</ul>

嘿兄弟,謝謝你。我爲這個表單和控制器切換到(comment_params)。它開始工作 – ApecBrah
