如何在 Rails 6 中使用 js.erb 视图 [英] How to use js.erb views in Rails 6

问题描述

是否有可能在 Rails 6 应用程序中使用 js.erb 视图?我明白了

Is there possibility to use js.erb views in Rails 6 application? I get

MyController#my_action is missing a template for this request format and variant.

request.formats: ["text/html"]
request.variant: []

迁移到 rails 6 后使用 js.erb 视图的操作出错.

error for actions using js.erb views after migration to rails 6.

在我的操作中，我只是为实例变量赋值:

In my action I just assign value to instance variable:

  def next_question
    @lesson = lesson
  end

在我有的路线

  put ':package_id/lessons/next_question', to: 'lessons#next_question', as: 'next_question'

并且有提交此请求的表格

And there is form for submit this request

 = form_tag next_question_path(@package), method: :put, remote: true 

如果我创建(用于测试)html.slim 文件，一切正常.如果我将 format.js 添加到控制器，我会得到 ActionController::UnknownFormat

If I create (for test) html.slim file, everything works well. If I add format.js to controller, I get ActionController::UnknownFormat

推荐答案

创建一个视图文件next_question.js.erb，然后做这个

Create a view file next_question.js.erb, then do this

def next_question
  @lesson = lesson

  respond_to do |format|
    format.js
  end
end

另外，在application.js文件中启用ujs，添加这一行

Also, enable ujs in application.js file, add this line

require("@rails/ujs").start()

试试看！
