Question

我在Rails应用程序中做了一个评论部分，但是当我发表评论并且页面被重新加载时，评论不会被保存。我没有任何错误。

在route.rb中有此文件：

resources :analyses, only: [:index, :create, :show, :destroy, :update] do
    collection do
      post :destroy_multiple
      get :start_multiple
      post :custom_create
    end

    member do
      resources :comparisons, only: :show, param: :document_id
    end

      resources :comments
  end

然后：

class Comment
  include Mongoid::Document
  field :name, type: String
  field :body, type: String
  embedded_in :analysis
  belongs_to :analysis
end

在：

class Analysis
  embeds_many :comments

然后：

class CommentsController < ApplicationController
  def create
    @analysis = Analysis.find(params[:analysis_id])
    @comment = @analysis.comments.create(params[:comment].permit(:name, :body))
    redirect_to analyses_path(@analysis)
  end

  def destroy
    @analysis = Analysis.find(params[:analysis_id])
    @comment = @analysis.comments.find(params[:id])
    @comment.destroy
    redirect_to analyses_path(@analysis)
  end
end

_comment.haml：

%p= comment.name
%p= comment.body
%p= time_ago_in_words(comments,created_at)
%p
  = link_to 'Delete',[comment.analysis, comment], method: :delete, data: { confirm: 'Are you sure you want to delete this comment?' }

和_form.haml：

= form_for([@analysis,@analysis.comments.build]) do |f|
  %p
    = f.label :name
    = f.text_field :name
  %p
    = f.label :body
    %br/
    = f.text_area :body
  %br/
  %p
    = f.submit

，然后在analyses / show.html.haml中输入：

%br/
= @analysis.comments.count
Comments
= render @analysis.comments
%h5
Add a Comment:
= render 'comments/form'

我在没有看到评论的地方犯了错误，还是必须以不同的方式来做所有事情？

Answer 1

尝试一下：

  def create
    @analysis = Analysis.find(params[:analysis_id])
    @comment = @analysis.comments.create(comment_params)
    redirect_to analyses_path(@analysis)
  end

  private 

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

评论部分不会保存评论
