用户在Rails中选择的CSS样式表 [英] User selected CSS stylesheet in Rails

问题描述

我正在Rails的网站上工作，我希望用户能够将CSS样式表更改为浅色或深色主题。

我在我的视图中有这个，所以我可以为样式表使用一个变量：

 <％= stylesheet_link_tag @current_stylesheet％> 
 

我试图通过在我的视图中有一个链接来改变这个变量：

 <％= link_to'Light Theme'，：action => set_light，：id => @projects％> 
  

在我的控制器中调用此函数：

  class ProjectsController< ApplicationController 
 def set_light 
 @current_stylesheet ='light'
 end 
 end 
  


b $ b

有没有办法让这样的工作？现在它说，项目/ set_light模板缺失，但我不想创建新模板，我只想调用set_light来更改样式表和刷新当前页面。

解决方案

以避免有轨道寻找一个' set_light模板，您可以向已经拥有的模板添加对操作结束的render调用。例如，只需添加

  render：action => 'style_chooser'
  

或

  render：template => 'style_chooser'
  

其中style_chooser是向用户呈现视图或更改




I'm working on a site in Rails and I'd like for the user to be able to change the CSS stylesheet to either a light or dark theme.

I have this in my view so that I can use a variable for the stylesheet:

<%= stylesheet_link_tag @current_stylesheet %>

I tried to change that variable by having a link in my view something like this:

<%= link_to 'Light Theme', :action => "set_light", :id => @projects %>

that calls this function in my Controller:

class ProjectsController < ApplicationController
  def set_light
    @current_stylesheet = 'light'
  end
end

Is there a way to make something like this work? Right now it says that the projects/set_light template is missing, but I don't want to make new templates, I'd just like to call set_light to change the stylesheet and refresh the current page. Any ideas on how to accomplish this, or maybe a better way to approach it?

解决方案

to avoid having rails look for a 'set_light' template you can add a render call to the end of your action for a template you already have. for instance, just add

render :action => 'style_chooser' 

or

render :template => 'style_chooser'

where style_chooser is the view you are presenting the user with or changing the style for
