How can I create a path that redirects back to the current page?
Eg. I'm on http://example/users/3
, I click on the link, and it redirects me to http://example/users/3
.
This seems like it should be very simple, but I can't find anything online and all my guesses return an 'undefined method' error.
I'm trying to print erb into an href link, so I think it has to be a path... something along the lines of
href="facebook/sharer/sharer.php?u=<%= path_to_current_url %>"
If it matters, I'm using Rails 4.0.10.
Try:
request.original_url
This will get the absolute url. Documentation:
http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url
您可以使用request.env ['REQUEST_URI']将该URL作为字符串获取。
您可以使用<%= link_to "Refresh", '#' %>
