Rails:如何在表单'submit'上指向结果页面

Question

我想在用户单击8个问题多项选择测验的提交按钮时将用户引导至"结果"页面,同时还将他们的答案保存到数据库中.

目前我正在使用'form_for'并传入current_user.单击提交时,它将指向User/show操作.我想转到详细说明用户结果的页面.我该怎么做呢？

这是我的(非常粗略的测试)形式,到目前为止,一个多项选择问题(由引导程序设计):

<%= form_for([current_user]) do |f| %>
  <p>
    <%= text_field(:user, :name) %>
  </p>
  <div class="btn-group-vertical clearfix form-group" data-toggle="buttons">
          <label class="btn btn-primary text-left">
            <input name="options" id="option1" type="radio" onclick="multiChoiceClick(1, 1)">A. Always. I'm the leader and should have the final say
          </label>
          <label class="btn btn-primary text-left">
            <input name="options" id="option2" type="radio">B. Sometimes, but I think the group should make decisions if possible
          </label>
          <label class="btn btn-primary text-left">
            <input name="options" id="option3" type="radio">C. I generally don't get involved. The group can make their own decisions without my help
          </label>
  </div>
  <p>
    <%= f.submit("Get my results!") %>
  </p>
<% end %>

我目前正在将text_field包含在用户名中作为测试.

我想知道如何将第一个多项选择问题"连线"给用户,但在点击"获取我的结果"时显示结果页面.

我可能在这段代码中有几个错误.如果我这样做,并且你有答案,请你指出我的错误并解释做正确的方法吗？很抱歉这么具体,但我之前有过一些评论只能指出什么是错的,没有别的选择.

谢谢.

编辑:

有人要求控制器,所以这里是:

class HomeController < ApplicationController
    def index
    end

    def whattypeofleader
        @user = current_user
        #@quiz_answer = current_user.quiz_answers(0).build
    end

    def post_params
        params.require(:quiz_answer).permit(:body, :user_id)
    end
end

我已将@quiz_answer注释掉,因为我不确定如何将其与表单相关联.在用户控制器中,用户has_many:quiz_answers和QuizAnswer belongs_to:user

重定向应该来自您的控制器.管理数据后,一个简单的:

redirect_to results_path

您的结果路径应该在您的config/routes.rb.

不要犹豫与控制器分享更多一点,看看我们是否可以更深入:)

[编辑]在评论之后

免责声明:不确定Rails的测验复数管理......

您的表单应该由new方法呈现,如下所示:

class QuizzesController < ApplicationController

  ...

  def new
    @user = current_user     #you now have access to the @user variable in your view
  end

  ...
  def create
    # do your thing with your params
    # usually, you want to redirect to the results page if the action has been saved
    # so let's say that you built an @object beforehand with the params you received
    # extactly like @DarkMousse answer :

    if @object.save
      redirect_to results_path
      flash[:notice] = "Thanks for submitting these questions"
    else
      render 'new'
    end

    # this way, if all is good, go to results_path, else, return to the 'new'

  end
  ...

end

为了访问这个动作,你必须有一个路径才能到达它,让我们去 config/routes.rb

YouApplicationName::Application.routes.draw do
  ...
  #it 'opens' the routes to access all method from your quizzes controller
  resources :quizzes
  resources :results
  ...
end

现在您可以访问测验/新.它将呈现视图views/quizzes/new,您可以在其中使用如下形式:

form_for @user do |f|
  # ... your form ...
end

请注意,由于new我们的QuizzesController中的方法,可以访问@user.

现在我们已经添加了一个results到我们的路由,rake routes在终端中你应该找到一个results_path导致你的(尚未创建:))ResultsController index方法.

它可能看起来像这样:

class ResultsController < ApplicationController
  def index
    # in order to access all the results in our view
    @results = Results.all
  end
end

这样,results_path导致此操作,默认情况下(感谢rails)调用views/results/index.html.erb渲染.
