Question

您好我已经开发了以下代码。

class SetupController < ApplicationController
  def update
    if current_user.update_attributes(user_params)
      flash[:success] = 'Profile complete'
      redirect_to user_profile_path(current_user)
    else
      flash[:danger] = errors(current_user)
      redirect_to setup_users(current_user)
    end
  end
end

get 'setup' => 'setup#edit'
patch 'setup' => 'setup#update'

但是在制作中我遇到以下错误。该页面没有做任何事情。它没有重定向。没有闪光。没什么。

有谁知道如何解决这个问题？

感谢您提前提供任何帮助。

Answer 1

这是怎么回事？

class SetupController < ApplicationController
  def update
    if current_user.update_attributes(user_params)
      flash[:success] = 'Profile complete'
      redirect_url = user_profile_path(current_user)
    else
      flash[:danger] = errors(current_user)
      redirect_url = setup_users(current_user)
    end
    redirect_to redirect_url
  end
end

像这样添加 -

class SetupController < ApplicationController
  def update
    if current_user.update_attributes(user_params)
      flash[:success] = 'Profile complete'
      redirect_to user_profile_path(current_user)
    else
      flash[:danger] = errors(current_user)
      redirect_to setup_users(current_user)
    end
    respond_to do |format|
      format.html
      format.json
    end
  end
end

或者您只需在循环结束时添加render json: {}或render 'edit'

即可

错误：找不到XxxController＃update的模板，渲染头：no_content
