Iron Router Meteor , Router.go alternative from server-side - meteor

I am using Meteor with Iron Router and Stripe. Everything is working great, but I cant figure out how to re-direct user to a final order complete page after the Stripe charge is completed.
On my client side I have a modal box that appears which contains a button that says, "Pay" When the Pay button is clicked an event is fired that calls up and opens Stripe Checkout.
The Stripe Checkout then initiates on the client and the user is able to enter the card details and submit the payment. The server side method for charging the card thru Stripe is completed and I also have some other basic database tasks that are being performed to log the result and complete the order status.
I have created a route using Iron router that I want the user to be re-directed too after the Stripe Payment is completed.
As of now the modal box continues to stay on the screen. I am trying to make the Router.go send user to the order page that had been setup after the order is finished.
I beleive the Iron Router Router.go is used client-side only. How can I complete the order process and make the client-side modal box disappear after the Stripe charge is completed and re-direct user to a final complete page.
When I use the Router.go on server-side I am getting error:
Exception in callback of async function: TypeError: Object function router(req, res, next) {//XXX this assumes no other routers on the parent stack which we should probably fix

You can't force the user's browser away from it's page if you don't already have some logic on the page to "remote control it". Fortunately there are a number of options for the latter:
If you are using a router you could make the route itself reactive, depending on the content of a subscribed collection. Alternatively, you can have an Tracker.autorun or an observeChanges block on your client side code that checks for changes to that "control" collection and then execute Router.go accordingly.
As for the control collection, a simple collection like:
var Control = new Mongo.Collection('control');
would do, and then you insert into it from the server when the event occurs (Control.insert({route: "newroute"})), and check for content changes on the client, for instance like so:
Control.find().observeChanges({
added: function(id, doc) {
Router.go(doc.route);
});

Oracle APEX button - link to URL and execute dynamic action

I am working with APEX 20.
I defined a button which links to a URL:
Behavior: "Redirect to URL" and my URL as Target - this works without any problem.
When this button is pressed, I have to change the status in a table in my data model.
I added a Dynamic Action which executes some PL/SQL code to update my table.
The problem is that when the button is pressed, the redirect is done and my dynamic action is
not executed.
Is there any way to change the sequence, executing the dynamic action first, and then the redirect?
Some background:
This application allows users to define + configure systems and queue them for automatic installation. The installation is done from a remote server, and must be triggered by calling a CGI script per URL. When the order is issued, the user should come back to the applications main page to work on other systems.
Therefore I choose a modal dialog to launch the order. The idea is:
On the system page press button "Install"
Modal dialog page opens
Here you press the usual "Do you really wish to install" button (since it will cost money now).
At this moment the status in the database must be altered, and the redirect to the URL must happen.
The modal dialog closes and the user is back on the system definition pages.
I tried to connect the button only with the dynamic action to update the database table,
followed by a "submit" action.
In this scenario I added a branch to the URL to be processed after page submit, which did not
work.
I also tried to intergrate the redirect to the URL into the PL/SQL code using apex_util.redirect_url, but I do something wrong, this part is simply ignored.
What you could try is:
Make the button with action "Submit Page"
Create a page process in the with point "Processing". This is where you'd execute the code to update the table. Add a when button pressed server sided condition.
Create a branch to redirect to the new page after submit with the same when button pressed server sided condition.
This is "the traditional" way of doing it in APEX - handle all database actions after page submit. No dynamic actions are needed in this case.

Direct to Specific Route when meteor auto refreshes

Im using meteor + Iron Router and I would like to handle (in the onbefore web hook) the case where meteor auto refreshes all connected clients and redirect to the home route ('/').
Is there a flag to determine when a refresh is caused by meteor live updating vs a client triggered refresh?
An auto-refresh triggered by a code change leaves Session variable values in-tact, whereas a client-triggered refresh will reset them all to null. So, if I understand you correctly, you could check for the presence of a Session variable in the Meteor.startup callback on the client and call Route.go('/') if it's null. Example:
if (Meteor.isClient) {
Meteor.startup(function() {
if (!Session.get('keyKnownToHaveValue')) {
Route.go('/');
}
});
}

where sfGuard checks out perms and credentials in order to implement Google's Oauth 2

I want to integrate Google's Oauth2 in my symfony-1.4 CRM. I have successfully implemented this, I have extended sfGuardAuth in my own module, and now mysfGuardAuth is being used for siging and signout. Is there where I handle Google's Oauth2 with 2 extra actions:
executeCkeckGoogleAccess();
executeOauth();
The problem is to checkout if Google's token is still a valid one, I have to redirect in each action of everymodule to the action checkGoogleAccess in mysfGuardAuth module.
What I want is to check this in an implicit way in the same place where symfony, or sfGuard or whatever checks for the right perms or credentials before executing or not executing the requested action.
I only want to write the code once.
Thank you.
After some research this is how sfGuard checks everything.
When you make a request to a module action, before the action is executed, a new sfContext is dispached.
The sfContext gets the user that extends sfGuardUser and has some methods that are executed. There is where perms, session status and everithing else is checked
The user must be configured in apps/yourApp/lib
By default is apps/yourApp/lib/myUser which extends sfGuardUser. The most apropiate way to achieve this is to create a new user class like: apps/yourApp/lib/yourAppUser which extends aswell sfGuardUser, and there extend the methods initialize and/or shutdown with the functionality you want.
By this way I have achieved to get Google's Oauth2 working in my app.
I hope this is usefull for more people.
UPDATE
All described above is true, but if you want to check something always before an action execution you must use filters instead of whats described before.
Filters are executed before each action, so there you can checkout whatever you need having access to the current context, and set up new attributes for the user. In my case I wanna check if the requested action needs a google token, if true, then Another filter will check if the user has alraedy a valid token, in that case, nothing happens, otherwise, the user is redirected to the module/action which handles google token requests.
Comunication between diferent filters, actions and requests are handled via user attributes.
the user is an object of the clas myOwnUser which extends sfGuardSecurityUser, there the function signOut is extended in order to delete all attributes saved in "myOwnNamespace"

How do you securely log out and clear all subscriptions?

I implemented my own login system, because I'm using a third party web service to authenticate users against an enterprise authentication system. As such, I built a form that calls a server method to make the web service call to the auth system, and if the credentials are valid, it sets a session variable with the user's id. This is how I change the template to show the main screen of the application and not the login screen. Works fine. And the logout button then just sets that userid session variable to false, effectively hiding the main application screen and showing the login form again.
<body>
{{#if loggedInUser}}
{{> navbar}}
{{> mainScreen}}
{{else}}
{{> customLogin}}
{{/if}}
</body>
Template.navbar.helpers({
loggedInUser: function () {
return Session.get('userName');
}
});
'click #logoutButton': function () {
Session.set("userName", false);
}
What I have discovered though, is that the local minimongo collections/subscriptions are still in the browser, and accessible in the console, after the user logs out.
I did some searching but didn't find concrete solutions as to how to properly clear out (or stop?) these subscriptions on the client. In fact, the top 3 hits on a search for "meteor publish subscribe " don't mention stopping or security upon logout.
One suggestion on SO was to save the subscription handle ... but I'm calling subscribe multiple times, so it seems I would have to store up an array depending on how many different subscribes the user triggered during their use of the application, and then go through them calling "stop" on each handle when logging out??
I'm hoping there's a simple way to stop all subscriptions... seems like a logical thing to do for security when a user clicks a logout button.
Thanks!
Could you not use .stop() function on the collection?
var subscription = Meteor.subscribe("info");
//on logout
subscription.stop();
According to the docs:
stop()
Cancel the subscription. This will typically result in the server directing the client to remove the subscription's data from the client's cache.
Updated: Maybe check out this package: Subs Manager. It appears they may be able to do what you want, specifically from their readme:
Clear Subscriptions
In somecases, we need to clear the all the subscriptions we cache. So, this is how we can do it.
var subs = new SubsManager();
// later in some other place
subs.clear();

Abort Asynchronous Web Service Call and redirect to another URL (ASP.NET Ajax)

In my webapp, I have a list of links generated from code-behind and bound to a repeater control. Clicking on a link opens a popup window, where, along with displaying some data, an asynchronous call to a WCF Service is made (through a javascript proxy). This service in turn calls another third party web service that might take a long time to respond. I am working with IE6, thats a unavoidable requirement.
Now, I abort this service on onunload if the user decides to not wait for the call to complete and just closes the popup window. The problem is, if the user clicks another link from the repeater immediately after, the new popup window opens but doesn't load the page (doesn't go to the supplied URL) till the previous asynchronous call has completed (I have verified this through Fiddler). Interestingly, this only happens for links within the same domain. If I change the link for one of the popus to, say, www.google.com, then the window opens and goes to the correct url as intended. But, for popups with links within my own domain, which are opened immediately after a popup window with an unfinished request was closed, it waits till the previous request completes before loading the url.
I have verified the correct way to abort a callback and abort does fire properly. I also know that I can only abort my client side call, and not the server side call and I don't care about it. My only requirement is that the browser load the next link regardless of the previous asynchronous response.
//Method to Call Service:
function GetData(Id) {
//call the service
Sys.Net.WebRequestManager.add_invokingRequest(On_InvokingRequest);
var service = new WrapperService();
service.GetData(Id, handleSuccess, handleError, null);
Sys.Net.WebRequestManager.remove_invokingRequest(On_InvokingRequest);
}
//method to get the current requests abort executor
function On_InvokingRequest(executor, eventArgs) {
var currentRequest = eventArgs.get_webRequest();
abortExecutor = currentRequest.get_executor();
}
//abort service on unload
function unload() {
if (abortExecutor != null) {
abortExecutor.abort();
}
}

Anybody faced this before? Its driving me nuts! Any help will be greatly appreciated.
The answer in one of your links sounds like the problem to me:
Browser waits for ajax call to complete even after abort has been called (jQuery)
Does your service require session state?
You could prove whether the problem is that IE itself won't issue the request by configuring IE to allow for more than 2 requests to the same domain. If it's being blocked because the aborted request is somehow eating up one of those connections, then increasing it should yield different results. If it still has the problem, it must be that the server is waiting to respond.
Configure IE for more than 2 requests:

Quote from one of the SO questions you linked:
It turns out I was completely wrong about this being a browser issue - the problem was on the server. ASP.NET serializes requests of the same session that require session state, so in this case, the next page didn't begin processing on the server until those ajax-initiated requests completed.
Unfortunately, in this case, session state is required in the http handler that responded to the ajax calls. But read-only access is good enough, so by marking the handler with IReadOnlySessionState instead of IRequiresSessionState, session locks are not held and the problem is fixed.
