How to get the current route in rails
提问by peeyush singla
I am building some rails sample application in which I am having two models User and Projects. Association between both is user has_many projects. Now the question is I am willing to provide some drop down for user's projects on top and if some one click on that one it will take that to project show page. But if user is at edit page of one project and select other project from dropdown I want him to reach edit page of new selected project same case for show page any idea. The solution I am looking for is e.g:- we can find current controller using params[:controller], find current action using params[:action] how can I find current route. Thanx in advance
我正在构建一些 Rails 示例应用程序，其中有两个模型 User 和 Projects。两者之间的关联是用户 has_many 项目。现在的问题是，我愿意在顶部为用户的项目提供一些下拉菜单，如果有人单击该项目，则会将其带到项目显示页面。但是，如果用户在一个项目的编辑页面并从下拉列表中选择另一个项目，我希望他到达新选定项目的编辑页面，以显示页面任何想法。我正在寻找的解决方案是例如：-我们可以使用 params[:controller] 找到当前控制器，使用 params[:action] 找到当前操作如何找到当前路线。提前谢谢
If someone want to see what is my code:- here is the link for github:- 'https://github.com/peeyushsingla/session_test.git/Here I am using simple link but actually I will provide some single drop down that will be displayed that will work for all the edit, show, new every action
如果有人想看看我的代码是什么：- 这里是 github 的链接：- ' https://github.com/peeyushsingla/session_test.git/这里我使用的是简单的链接，但实际上我会提供一些下拉菜单将显示适用于所有编辑、显示、新建的每个操作

To retrieve the URLs:
要检索 URL：
# Current URL:
request.original_url
# Current relative URL:
request.request_uri
Additionally, you can check with the current_pagemethod whether you are in a certain route.
此外，您可以使用该current_page方法检查您是否在某条路线上。
current_page?(my_path)
# => true / false
For Rails 4 use:
对于 Rails 4 使用：
# Current URL:
request.original_url
# Current relative URL:
request.fullpath

You can use url_for
您可以使用 url_for
def current_path(params={})
url_for(request.params.merge(params))
end
URL example http://localhost:3000/posts
网址示例 http://localhost:3000/posts
current_path -> /posts
current_path -> /posts
current_path(order: asc) -> /posts/?order=asc
current_path(order: asc) -> /posts/?order=asc
