通过按钮/链接访问rails控制器中的方法

我试图按照此主题的解决方案 - Rails 3 link or button that executes action in controller

我在routes.rb文件中定义了:update_question:

  resources :surveys do
    put :update_question, :on => :member
  end

并在我的控制器中:

class SurveysController < ApplicationController
  before_action :set_survey, only: [:show, :edit, :update, :destroy]
  before_action :set_question

  # GET /surveys
  # GET /surveys.json
  def index
    @surveys = Survey.all
  end

  # GET /surveys/1
  # GET /surveys/1.json
  def show
  end

  def survey
    @survey = Survey.find(params[:survey_id])
  end

  # GET /surveys/new
  def new
    @survey = Survey.new
  end

  # GET /surveys/1/edit
  def edit
  end

  def update_question
    flash[:alert] = "getting there man"
  end

并在html中列出了链接:

<%= link_to "Next Question", update_question_survey_path(@survey), {:method => :put} %>

但是当我点击链接时出现此错误:

Template is missing
Missing template surveys/update_question, application/update_question with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}.

似乎可以避免它正在寻找一个视图 - 但实际上我只是希望它在我的测量控制器中运行该方法并更新正在显示的问题。也许我会以错误的方式解决这个问题,非常感谢任何帮助/建议!

那是因为操作已正确到达,但Rails尝试渲染某些内容。默认情况下,它将查找具有相同操作名称的视图文件。

你应该这样做:

def update_question
  set_survey
  # do stuff
  flash[:alert] = "getting there man"
  redirect_to survey_path(@survey)
end
