嵌套编辑路径不工作

Question

试图找出_comment.html.erb文件中的编辑路径。

不断收到此错误：

ActiveRecord::RecordNotFound in CommentsController#edit 
Couldn't find Article with 'id'=#<Comment::ActiveRecord_Associations_CollectionProxy:0x007fcac37359e8> 

不知道如何计算如何写正确的路径。

评论控制器

class CommentsController < ApplicationController 
    def create 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.create(comment_params) 
    redirect_to article_path(@article) 
    end 

    def show 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.find(params[:id]) 
    end 

    def edit 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.find(params[:id]) 
    end 


    def destroy 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.find(params[:id]) 
    @comment.destroy 
    redirect_to article_path(@article) 
    end 

    private 
    def comment_params 
     params.require(:comment).permit(:commenter, :body) 
    end 
end 

_comment.html.erb

<p> 
    <strong>Commenter:</strong> 
    <%= comment.commenter %> 
</p> 

<p> 
    <strong>Comment:</strong> 
    <%= comment.body %> 
</p> 

<p> 
    <%= link_to 'Edit', edit_article_comment_path(@article.comments, comment) %> 
</p> 

<p> 
    <%= link_to 'Show', [comment.article, comment] %> 
</p> 

<p> 
    <%= link_to 'Destroy Comment', [comment.article, comment], 
       method: :delete, 
       data: { confirm: 'Are you sure?' } %> 
</p> 

路线

resources :articles do 
    resources :comments 
    end 

怎么办我写出正确的道路？

而且，早期的路我已经是这样的：

<%= link_to 'Edit', edit_article_comment_path(@article, comment) %> 

但它会变成一个空白的编辑形式，即，没有一个文本框有任何填写...因此为什么我试过其他路径。

任何帮助，将不胜感激。

谢谢。

评论_form.html.erb

<%= form_for([@article, @article.comments.build]) do |f| %> 
    <p> 
    <%= f.label :commenter %><br> 
    <%= f.text_field :commenter %> 
    </p> 
    <p> 
    <%= f.label :body %><br> 
    <%= f.text_area :body %> 
    </p> 
    <p> 
    <%= f.submit %> 
    </p> 
<% end %> 

文章show.html.erb

<p> 
    <strong>Title:</strong> 
    <%= @article.title %> 
</p> 

<p> 
    <strong>Text:</strong> 
    <%= @article.text %> 
</p> 

<h2>Comments</h2> 
<%= render @article.comments %> 

<h2>Add a comment:</h2> 
<%= render 'comments/form' %> 

<%= link_to 'Edit', edit_article_path(@article) %> | 
<%= link_to 'Back', articles_path %> 

Answer 1

有一个在_comment.html.erb问题

<%= link_to 'Edit', edit_article_comment_path(@article.comments, comment) %> 

应该

<%= link_to 'Edit', edit_article_comment_path(@article, comment) %> 

But it would turn up a blank edit form, ie, none of the text boxes had anything filled in

如果传递正确的价值观在form_for

<%= form_for [@article, @comment] do |f| %> 

EDIT2

您应该检查井的问题是要传递的新实例每次评论，即使是编辑操作。这就是为什么你没有得到形式的任何值

<%= form_for([@article, @article.comments.build]) do |f| %> 

将其更改为

<%= form_for([@article, @comment]) do |f| %> 

并确保你在CommentsController都new和edit行动或无论你在哪里分配@article和@comment渲染comments/_form

class CommentsController < ApplicationController 
    def new 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.new 
    end 

    def edit 
    @article = Article.find(params[:article_id]) 
    @comment = @article.comments.find(params[:id]) 
    end 

    #... 
end
