修復conversation_id從NULL

Question

我用郵箱gem替換了我的自定義收件箱郵件系統。我在應用程序的Q &功能上遇到問題。該問題未被髮送到用戶收件箱，因此可以回答。該問題顯示在notifications表中，但conversation_id爲NULL。如果沒有生成conversation_id，問題將永遠不會傳遞給收件人收件箱。

有人可以看看我的代碼，看看出了什麼問題嗎？

問題控制器：

def index 
    @questions = Question.all 
    respond_with(@questions) 
end 

def show 
    @question = Question.find(params[:id]) 
    @questions = Question.order("created_at DESC") 
    respond_with(@questions) 
end 

def new 
    @question = Question.new 
    respond_with(@question) 
end 

def create 
    @question = Question.new(params[:question]) 
    if @question.save 
    #Original code @message = Message.create 
    @message = current_user.messages.new(:subject => "You have a question from #{@question.sender_id}", 
          #Original code :sender_id 
          :notification_id => @question.sender_id, 
          #Original code :recipient_id 
          :receiver_id => @question.recipient_id, 
          :body => @question.question) 

    @question.message = @message 
    @question.save 
    redirect_to questions_path, notice: 'Your question was saved successfully. Thanks!' 
    else 
    render :new, alert: 'Sorry. There was a problem saving your question.' 
    end 
end 

    def update 
    @question = Question.find(params[:id]) 
    @question.update_attributes(:answer => params[:question][:answer]) 
    redirect_to user_messages_path(current_user, :mailbox => "inbox") 
end 
end 

消息控制器：

def index 
     redirect_to conversations_path(:box => @box) 
    end 

    # GET /message/new 
    def new 
    @message = current_user.messages.new 
    end 

    # POST /message/create 
    def create 
    @recipient = User.find(params[:user]) 
    current_user.send_message(@recipient, params[:body], params[:subject]) 
    flash[:notice] = "Message has been sent!" 
    redirect_to :conversations 
    end 
    end 

消息形式：

<%= @user %> 
<%= form_tag({controller: "messages", action: "create"}, method: :post) do %> 
    <%= label_tag :subject %> 
    <%= text_field_tag :subject %> 
    <%= label :body, "Message text" %> 
    <%= text_area_tag :body %> 
    <%= text_field_tag(:user, "#{:user_id}") %> 
    <%= submit_tag 'Send message', class: "btn btn-primary" %> 
<% end %> 

問題形成：

<h1>New Question</h1> 
<%= form_for @question do |f| %> 
<%= @question.errors.full_messages.each do |msg| %> 
<li><%= msg %></li> 
<% end %> 
    <ul> 
     <li><%= f.text_field :question, {:placeholder => 'Please add your question...'} %></li> 
    <%= f.hidden_field :sender_id, :value => current_user.id %> 
     <li><%= f.hidden_field :recipient_id, :value => params[:user_id] %></li> 
     <li><%= f.submit %></li> 
     </ul> 
     <% end %> 
     <%= link_to "Back", questions_path, :class => "button" %> 

Answer 1

看起來你不像在任何地方設置conversation_id？嘗試將它作爲選項散列的一部分傳遞給current_user.messages.new（...）

Answer 2

我覺得這是你的問題：

<li><%= text_field_tag :question, {:placeholder => 'Please add your question...'} %></li> 

這將設置PARAMS [：提問]是一個字符串。你的控制器操作期望它是一個散列。也許它應該是

text_field_tag "question[text]" ... 

或任何包含問題文本的字段是。
