I am trying to redirect a user to a different URL in coldfusion after the user logs out. Nothing comes to the top of my head besides linkTo() or urlFor() to accomplish this, but the thing is, I am not linking to another cfm page, I am wanting to send the user to a different URL completely.
What is the best way to send a user to a new URL after they signout, check code below.
public string function logOut() {
auth.logOut();
return forward('public.Home', 'home');
}
The <cflocation> tag comes to mind. Inside a cfscript block, it's the location() function. Details are in the documentation.

I'm currently developing an ckan extension, where i need to redirect to a url on a different domain.
In my plugin i defined a custom action function:
#side_effect_free
def download_json(context, data_dict):
toolkit.redirect_to('http://my.json-builder.com?id=1234')
But when i call this endpoint i just get following response:
response screenshot
So i assume that the action function is called, but the redirect_to call does not redirect to the url i defined.
Thanks for your help!

It's a bit hard to figure out what you're trying to accomplish but here's a few things I hope will help.
Short Answer:
No, you can't redirect from an API endpoint in CKAN. The endpoint response in CKAN is built up and expects certain things from your action. Your action should return some kind of result. In your case it's returning nothing but trying to redirect. A logic action function with IActions is not the same as a Blueprint or pylons controller action.
See Making an API request docs, specifically the breakdown of an API response in CKAN. Also, you can review the pylons implementation that builds up the API response or the flask blueprints implementation.
More Info to help with your approach:
You say you are trying to call an endpoint that redirects a user to a different domain url. Based on this consider the following:
The first thing I thought you wanted was to have a url that someone goes to through the web interface of your site and are redirected to another site. In this case your example code of toolkit.redirect_to('http://my.json-builder.com?id=1234') makes sense and works for a custom controller action using/implemented with IRoutes or if you're using flask then IBlueprint. A User would go to a URL on your site such as http://localhost.com/download_json and be redirected to the new URL/site in their browser.
If you are intending this to be an API call for other users this starts to feel a little bit odd. If a user is using your API, they would expect to get results from your site in JSON CKAN's API is designed to return JSON. Someone consuming your API endpoint would not expect to be redirected to another site e.g. if I called http://localhost.com/api/3/action/download_json I would expect to get a JSON object like
{
help: "http://localhost/api/3/action/help_show?name=download_json",
success: true,
result: {
...
}
}
They would look for success to make sure the call worked and then they would use the result to keep moving forward with their desired processes. If you do want someone via an API to get redirect info I'd likely return the redirect url as the result e.g. result: {'redirect_url': 'http://my.json-builder.com?id=1234'} and document this well in your extension's API docs (e.g. why you're returning this endpoint, what you expect someone to do with it, etc).
If this is an API call for your own extension I'm guessing what you are trying to do is use my.json-builder.com to build a json of something (a dataset maybe?) and return that json as the result at your endpoint or maybe even consume the result to make something else? If that's the case, then in your function you could make the call to my.json-builder.com, process the results and return the results to the user. In this case, you're not actually wanting to redirect a user to a new site but instead make a call to the new site to get some results. If you actually want the results for your extension you don't need an additional endpoint. You could make the call from your extension, consume the results and return the desired object you're trying to create.
Hope this helps and sorry if I've miss-understood completely.
In my web application, I have a path as /search.
I also have a cookie named city set as CityA or CityB depending on what the user selected previously. I have set up Google Analytics to monitor the Visitor Flow.
My question is, how can I override the path /search to show up as /cityA/search or /cityB/search in the Analytics Behavior Flow menu, depending on the cookie value?
PS. It is a Rails app and actually changing the URL is not feasible at this point, since I will then have to reconfigure my Routes.rb file and update links everywhere.
Edit:
I have to use ga.js. Moving to Universal Analytics(analytics.js) is beyond my control at the moment.
In your analytics.js snippet you should see the following line:
ga('send', 'pageview');
You can pass an additional argument to the send method that overrides the page path. In your case it would look something like this:
ga('send', 'pageview', {
page: 'cityA/search'
});
You'd have to add some Rails logic in your .erb file to adjust the page value based on the cookie, but that shouldn't be too much trouble.
For reference, here's some information on the send method and the arguments it accepts:
https://developers.google.com/analytics/devguides/collection/analyticsjs/method-reference#send
This may be weird. Here is the scenario:
I have a view. And there are 2 clients connected to my django app. what i want is, when client1 sends a request to my view; i want to redirect client2 to another url. for example (pseudo-like) :
def some_view(request, other_clients_username):
try:
client2 = UserProfile.objects.get(username=other_clients_username)
except:
return HttpResponseNotFound('user not found')
client2.redirect('/door-screen/')
return HttpResponse('%s redirected successfully', %client2.username)
client1 sends a request to some_view with a username parameter.
If user exists, the client which is logged in by user should be redirected to door-screen page.
Before this i never needed something like this. I even cant imagine how to do this. Redirecting a user which is not request's owner.
Any kind of help would be great.
Thank you.
One solution to your problem would be to use websockets or a library like Pusher. Basically you'd send a message out on the wire within pusher that would tell client2's browser to redirect to a given URL. Obviously this is fairly easy to get around if a user knows that's going to happen.
Anyway, your backend view would look something like this:
p = pusher.Pusher(app_id='your-pusher-app-id', key='your-pusher-key', secret='your-pusher-secret')
p[client2.pusher_channel].trigger('redirect', {'url': '/door-screen/'})
Note that this assumes you're using https://github.com/pusher/pusher_client_python
Your template would need to pass the pusher channel though so client2's browser connects to the right channel. You can do that by either storing the channel id in a hidden input, rendering it as a var in javascript on the template itself, or you could even have it be passed through an ajax call. Though I'd probably go with one of the first two just because it's significantly easier.
I'm trying to redirect the browser back to the site root and also pass a variable in order to trigger a JS notification function... This is all with Django.
What I have now is this:
urls.py:
url(r'^accounts/password/reset/complete/$', views.passwordResetComplete,
name='password_reset_complete'),
views.py:
def passwordResetComplete(theRequest):
return redirect(home(theRequest, 'Password reset successful'))
def home(theRequest, myMessage=None):
.........
return render_to_response('new/index.html',
{
"myTopbar": myTopbar,
"isLoggedIn": isLoggedIn,
"myMessage": myMessage
},
context_instance=RequestContext(theRequest)
)
I get this error:
NoReverseMatch: Error importing 'Content-Type: text/html; charset=utf-8.......(gives full HTML of page)
I've been working around a few different solutions and nothing seems to work in the way that I need. The closest I've got is to redirect to '/?query-string' with a JS function in root to check for that query-string and run the function if it's present. However, that leaves the query-string in the URL for the duration of the user's navigation of the site (which is 100% AJAX). I want to avoid having any strings/long hrefs in the URL.
Would be really grateful if anyone can tell me how to solve this problem.
HTTP is a stateless protocol, which means that each and every request is entirely unique and separated from anything and everything that has ever been done before. Put more simply, the only way (in HTTP) to "pass a variable" with a URL is to add it to the URL itself (/someobject/1/, for example, where 1 is an object id) or in the querystring (?someobject=1). Either way, the information is embedded in the URL and it's up to your application to decipher that information out of the URL and do something with it.
The concept of a "session" was introduced as a way to provide state to the stateless protocol that is HTTP. The way it works is that the server sends the client a cookie containing some identifiable information (usually, just a session id). Then, the client sends the cookie back to the server in the request headers with every request. The server sees the cookie, looks up the session and continues on seamlessly with whatever is in progress. This is not true state, but it does provide the ability to essentially mimic state, and it's the only way to pass data between requests without actually embedding the data in the URL.
If all you need to return back is a message to the user such as "Password reset successful", you can and should simply use Django's messages framework, which itself uses the session pass the message. It sets a cookie for the client, so that you can redirect to any URL. The cookie will be passed back with the request for that new URL, and Django will add the message from the session into the appropriate place in your template for that URL.
If you need to actually invoke a bit of JavaScript, then you should make the request via AJAX. In the response, you can return any data you want in via JSON (and act on that data however you like) or even return Javascript to be run.
Following the redirect docs, you cannot simply redirect to a view, but only to a url or an object/view that is a assigned to a url already. Thus, you have 2 options:
a) Call the view directly like that:
return home(theRequest, 'Password reset successful')
b) Add a Url patterns like that:
url(r'^your_patterns/$', views.home, msg='',name='home'),
Then you will be able to do what you initally did:
return redirect(views.home,('Password reset successful',))
or from my point of view, even tidier:
return redirect('home',('Password reset successful',))
I have a Django admin action called "Email selected members". Check some members and click the Go button and the user's mail program is opened. The emails of the selected members have been pre-entered.
This works by a Django HttpResponseRedirect(uri) with the uri being "mailto:email1,email2..
where the addresses email1, email2 ... were looked up on the server.
The only problem is that that the browser re-directs to a blank page as well a opening the client mail program.
Is there any way to avoid this?

This question is a little old, but I just went through this and I think I can help anyone looking for an answer in the future.
I ran into this problem because the website I was building had a built-in tracking system that tracked the URLs of outbound links for self-hosted ads. If I don't redirect, there is no way (without changing the way it was implemented) to track the click, since I'm not using an API or anything.
The easy fix was to do what you did, sending back an HttpResponse() whose content is the meta tag
<meta http-equiv="refresh" content="0;url=mailto:youremail#test.com" />
This causes the page to refresh on load, which triggers the mailto: action.
Now we're left with an open window, but we can't close the window using Javascript's window.close() method. I do believe that this solution should work, however. Call that Javascript function after the refresh has been successful.
Unfortunately, I haven't tested this, but these two methods should accomplish a mailto: redirect that does not leave a blank window/tab behind.
Hope this helps!
Don't use HttpResponseRedirect. Just make the mailto: line a link. Email selected members
I don't think it is possible. RFC 2616 says re 302 redirect:
The temporary URI SHOULD be given by
the Location field in the response.
Unless the request method was HEAD,
the entity of the response SHOULD
contain a short hypertext note with a
hyperlink to the new URI(s)
So the blank page that I see is the (very) short hypertext note. The browser gets the redirect instruction, pops up a temporary page with the redirect message, then retrieves the redirected URL. But with a mailto: URL the temporary page obviously remains.
