Is there a way to include a redirect in a link_to? I want to just refresh the current page after a delete. But, you can delete the same record from multiple views in the app.
This is the link_to:
<%= link_to 'Delete', expense, confirm: 'Are you sure?', method: :delete, :class => 'btn btn-mini btn-danger' %>
If not, does it make sense to save the current_url in flash[:fromurl] then put that in the Controller destroy section like this:
respond_to do |format|
format.html { redirect_to flash[:fromurl] }
format.json { head :no_content }
end
Thanks for the help!
You can use the redirect_to :back
:
respond_to do |format|
format.html { redirect_to :back }
format.json { head :no_content }
end
It uses the header "HTTP_REFERER" from the request:
redirect_to :back
# is a shorthand for:
redirect_to request.env["HTTP_REFERER"]
In Rails 5 ( Official Docs ) you can use the updated: redirect_back(fallback_location: root_path)
Using this redirects the user to the referring page (previous page, the same as redirect_to :back
). If this isn't possible, it then redirects to a fallback location specified in the controller.
An example of a method in your controller (this redirects the user to the root path as a fallback location):
def some_method
#Your Code Here
redirect_back(fallback_location: root_path)
end
An example of a method for deleting an expense
and redirecting back, with a fallback to the root_path
:
def destroy
@expense.destroy
redirect_back(fallback_location: root_path)
end
Below are some other examples of the fallback_location
's that can be used to redirect the browser back to a specific page, if the referring page cannot be redirected to:
redirect_back fallback_location: "http://www.google.com" #Redirects to Google (or any website you specify)
redirect_back fallback_location: "/images/screenshot.jpg" #Redirects to a local image
redirect_back fallback_location: posts_path #Redirects to the 'posts' path
redirect_back fallback_location: new_user_path #Redirects to the new user path
