[ACCEPTED]-Rails 3: How to "redirect_to" in Ajax call?-redirect
Finally, I just replaced
redirect_to(:controller => 'jobs', :action => 'index')
with this:
render :js => "window.location = '/jobs/index'"
and it 1 works fine!
There is very easy way to keep the flash 5 for the next request. In your controller 4 do something like
flash[:notice] = 'Your work was awesome! A unicorn is born!'
flash.keep(:notice)
render js: "window.location = '#{root_path}'"
The flash.keep will make sure the 3 flash is kept for the next request.
So when 2 the root_path is rendered, it will show the given 1 flash message. Rails is awesome :)
I think this is slightly nicer:
render js: "window.location.pathname='#{jobs_path}'"

In one of my apps, i use JSON to carry on 3 the redirect and flash message data. It 2 would look something like this:
class AccessController < ApplicationController
...
def attempt_login
...
if authorized_user
if request.xhr?
render :json => {
:location => url_for(:controller => 'jobs', :action => 'index'),
:flash => {:notice => "Hello #{authorized_user.name}."}
}
else
redirect_to(:controller => 'jobs', :action => 'index')
end
else
# Render login screen with 422 error code
render :login, :status => :unprocessable_entity
end
end
end
And simple 1 jQuery example would be:
$.ajax({
...
type: 'json',
success: functon(data) {
data = $.parseJSON(data);
if (data.location) {
window.location.href = data.location;
}
if (data.flash && data.flash.notice) {
// Maybe display flash message, etc.
}
},
error: function() {
// If login fails, sending 422 error code sends you here.
}
})
Combining the best of all answers:
...
if request.xhr?
flash[:notice] = "Hello #{authorized_user.name}."
flash.keep(:notice) # Keep flash notice around for the redirect.
render :js => "window.location = #{jobs_path.to_json}"
else

def redirect_to(options = {}, response_status = {})
super(options, response_status)
if request.xhr?
# empty to prevent render duplication exception
self.status = nil
self.response_body = nil
path = location
self.location = nil
render :js => "window.location = #{path.to_json}"
end
end

I didn't want to modify my controller actions 1 so I came up with this hack:
class ApplicationController < ActionController::Base
def redirect_to options = {}, response_status = {}
super
if request.xhr?
self.status = 200
self.response_body = "<html><body><script>window.location.replace('#{location}')</script></body></html>"
end
end
end
