尽管保存功能有效，您如何修复 rails 中缺少模板的错误？

Question

我正在尝试发送消息，然后让它们出现在聊天框中。每次我发送消息时，都会导致以下错误。如果我刷新页面并打开聊天框，它会包含我上次输入的消息（意味着保存！正在工作）。是否有可以解决此问题的“路径”变量的特殊用法？

错误：缺少模板消息/创建，应用程序/创建 {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, : builder, :raw, :ruby, :coffee, :haml, :rabl, :jbuilder]}

消息控制器（相关功能）

  def create
    @conversation = Conversation.find(params[:conversation_id])
    @message = @conversation.messages.build(message_params)
    @message.user_id = current_user.id
    @message.save!
    @path = conversation_path(@conversation)   
  end

对话控制器（相关功能）

  def create
    if Conversation.between(params[:sender_id],params[:recipient_id]).present?
      @conversation = Conversation.between(params[:sender_id],params[:recipient_id]).first
    else
      @conversation = Conversation.create!(conversation_params)
    end

    render json: { conversation_id: @conversation.id }
  end

  def show
    @conversation = Conversation.find(params[:id])
    @reciever = interlocutor(@conversation)
    @messages = @conversation.messages
    @message = Message.new
  end

Answer 1

在Messages Controller中，你试过了吗：

def create
  @conversation = Conversation.find(params[:conversation_id])
  @message = @conversation.messages.build(message_params)
  @message.user_id = current_user.id
  @message.save!
  redirect_to @conversation
end

Answer 2

确保你的 jquery_ujs 被正确加载。

或者尝试使用 //= require_tree 。在你的 application.js 中一次
