Ruby on rails ActionController:：CommentsController中的ActionController错误#创建

下面是控制器

    class CommentsController < InheritedResources::Base
    def comment_params
        params.require(:comment).permit(:name, :email, :body, :post_id)
    end

    def create
        @comment = Comment.new(params[:comment_params])
        if @comment.save
            flash[:notice] = 'Comment was succesfully posted.'
            redirect_to(@comment.post)
        else
            flash[:notice] = "Error creating comments: #{@comment.errors}"
            redirect_to(@comment.post)
        end
    end
end

通过注释redirect_to in else块将通过另一个错误，即缺少模板

我尝试过以前问过的几个问题的解决方案，但没有任何帮助

即使未保存，您的else块中的用户也会重定向到@comment.post。所以基本上是零。 我不认为你的评论被保存。试着这样做，看看是否有任何错误

if @comment.save! # this will show errors if any
  ...
else
  post = Post.find(params[:post_id])
  redirect_to post
end

我想你的情人一定有身份证。如果没有，则@comment.post也将为零。在if和else块中都会导致该错误

else
   flash[:notice] = "Error creating comments: #{@comment.errors}"
   redirect_to(@comment.post) <--
end

应该是哪一个

@comment = Comment.new(comment_params)

不是

params[：comment\u params]

而是

comment\u params

，您应该将

create

操作更改为该操作，并确保设置了

post\u id

：

class CommentsController < InheritedResources::Base
    def comment_params
        params.require(:comment).permit(:name, :email, :body, :post_id)
    end

    def create
        @comment = Comment.new(comment_params)
        if @comment.save
            flash[:notice] = 'Comment was succesfully posted.'
            redirect_to(@comment.post)
        else
            flash[:notice] = "Error creating comments: #{@comment.errors}"
            redirect_to(@comment.post)
        end
    end
end

class CommentsController

你也可以发布你的表单吗？通过注释重定向到else块将通过一个错误：

缺少模板注释/create，继承的资源/base/create，应用程序/create和{：locale=>[：en]，：formats=>[：html]，：variants=>[：erb，：builder，：raw，：ruby，：coffee，：arb，：jbuilder]}。搜索地址：“*”c:/sites/myrubyblog/app/views“*”c:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/2.2.0/gems/designe-4.1.1/app/views“*”c:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/2.2.0/bundler/gems/activeadmin-f0243d495067/app/views“*”c:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/kaminari/17.0/views”>
@comment = Comment.new(comment_params)

class CommentsController < InheritedResources::Base
    def comment_params
        params.require(:comment).permit(:name, :email, :body, :post_id)
    end

    def create
        @comment = Comment.new(comment_params)
        if @comment.save
            flash[:notice] = 'Comment was succesfully posted.'
            redirect_to(@comment.post)
        else
            flash[:notice] = "Error creating comments: #{@comment.errors}"
            redirect_to(@comment.post)
        end
    end
