Is there a way to check if a cakePHP action is being called from an swf/flash movie like there is for Ajax using the requestHandler?
Put a named parameter in the URL that Flash is requesting:
eg. http://www.example.com/controller/action/flash:true
Check for this named parameter in your controller (or AppController) code:
if (isset($this->params['named']['flash'])) {
...
}
I don't believe so. A better option might be to create discrete controller actions that you only use from your Flash app.
Not the way I think you mean. The requestHandler can detect the type of request, but I think you're looking for the request source. It might be worth trying the getReferrer() method, but you may end up needing to add a click handler to the swf (if it's yours and you have that access).

What technique shall one use to implement batch insert/update for Backbone.sync?
I guess it depends on your usage scenarios, and how much you want to change the calling code. I think you have two options:
Option 1: No Change to client (calling) code
Oddly enough the annotated source for Backbone.sync gives 'batching' as a possible reason for overriding the sync method:
Use setTimeout to batch rapid-fire updates into a single request.
Instead of actually saving on sync, add the request to a queue, and only batch-save every so often. _.throttle or _.delay might help you here.
Option 2: Change client code
Alternatively, instead of calling save on your models, you could add some sort of save method to collections. You'd have to track which models were actually modified and hence in need of update, since as far as I can tell, Backbone only knows whether they're new or not (but I could be wrong about that).
Here's how I did it
Backbone.originalSync = Backbone.sync;
Backbone.sync = function (method, model, options) {
//
// code to extend sync
//
// calling original sync
Backbone.originalSync(method, model, options);
}
works fine for me , and I use it to control every ajax request coming out of any model or collection
I have a project I'm developing which includes articles that can be commented on (comments stored in separate table of course). I want to perform pre logic on a field from each comment, wherever they are loaded through-out the app. The data logic I want to performed is from a custom written component.
The logical place to me that this could be achieved globally is from the comment model, but I could be wrong.
I'm not even 100% if I can use a component from a model, but I've been trying to do this logic using the afterFind() call-back function:
function afterFind($results) {
foreach ($results as $key => $val) {
if (isset($val['Comment']['created'])) {
$results[$key]['Comment']['created'] = $this->Dateconvert->howLongAgo($val['Comment']['created']);;
}
}
return $results;
}
I have tried echoing from inside this function and it doesn't actually seem to be getting called but searching hasn't revealed any functions that do, but I believe afterFind() is best to illustrate what I'm trying to achieve.
So I am looking for a solution where I can performed the post-load logic on articles comments, whether they are being loaded from other controllers with associations to comments or in the comments controller. Basically a global one hit solution :D
cakephp indicates that components are for controllers and behaviours for models and helpers for view...
knowing that first, you may also know that you can use any part of it wherever you want because cake still php, though is not recomended... if is a library of functions you may want to put it inside the libs folders and access it from there.
how, easy use App::import('component', 'nameComponent'); component can be lib, controller, etc..
Having said that, afterFind is a good place to do after load things, remember that this function is call ONLY when a find is used, if you use, any other like query or save or update it won't be called.
hope this helps you :)
I have an admin controller that I would like to utilize functions in other controllers (these functions do not represent pages that someone would load in their browser), but it cannot utilize those functions because the functions in the other controllers are private. They are private because I don't want the public to access them. Is there a way to make a controller function not accesible to the public without making the function private or protected?
public function __blah(){
// function that can't be accessed from outside, but can be called from other functions
}
Based on what I've read in the comment of the answer Piotr gave you:
You don't use an admin controller. You want to use admin prefixes:
http://book.cakephp.org/view/950/Prefix-Routing
And authentication:
http://book.cakephp.org/view/1250/Authentication
If you call - and thats how your comment sounds like - one controller from another you're doing something totally wrong in an MVC framework. If it should be re-usable code it should go into components if it's about admin action use the prefix routing and admin_* methods, auth component and protected methods for what you call "helper" methods.
Yes.
You have a lot of information in the CakePHP Book about ACL (access control list) and that is exactly what you're looking for.
Or you may use Auth component.
I see three possible solutions (they can also be combined):
The first solution is to move the code you want to reuse to components (as mentioned by burzum).
The second solution depends on your code. It's possible that you do stuff in the controller which should be done in the model. In this case, move the respective code to the model.
The third solution is to put the code you want to reuse into plain old PHP classes and load them as vendor files.
So GET forms make the usual urls like
.../search/?q=apple
Can you make a form create urls like
.../search/q:apple/
Thanks, guys. I've found a different solution. I just submit the form as a POST and in the controller's action I read the post data and create a url with the post data as named params and then $this->redirect('...'); to it.
The methods to create these URL's can be found here: http://book.cakephp.org/view/842/url
If I understand you correctly, you're not looking to create a different URI, per se, but rather to serialize the form data in a different way. In other words, you're interested in modifying the query string rather than the URI itself.
As far as I know, that's the way that forms serialize their data and there's no way to truly override this behavior. If you really want to do this, I suspect you'll have to capture the submit event, manually serialize the form data into the format you want, append that format to the form's action value, make a custom request to the page (via location.href, etc.) and return false so that the form itself never actually gets submitted.
Of course, you could also submit via Ajax where you have a little more control.
I'm not aware of any other way to do what I think you're asking.
i need some help
which is when i on my index.ctp/view.ctp, i need to call to my controller function to perform some task. what code i can use to perform this action?
i need to call to my controller function, which send in a value (user_id) to the function and get me a certain action. how can i do that? i might calling in a javascript function as well.
If you need to call a Controller function from the View, you're doing it wrong. It's not proper MVC.
Having said that, requestAction would be the proper, albeit slowest way to do so. You could hack around a bit more and get an instance of the Controller from the ClassRegistry. But I'd seriously recommend you to restructure your program flow so you don't need to do this to begin with.
You should probably perform the task in the controller before you get the view. But if you need to do some view work on the data you are displaying you might want to consider making a Helper class.
http://book.cakephp.org/view/101/Creating-Helpers
If your task doesn't generate any output - you might want to consider doing it in the controller before you even get to the view stage.
If your task has some form of output - use requestAction with a view Element

That link should be a good starting point. There are also good posts by Mark Story on his blog that detail the actual performance of requestAction and it really isn't that bad if you don't abuse it all over the place.

If you really need to trigger some sort of logic in a predictable way and that logic might happen in more than one place you can also use an event observer pattern to trigger the controller action you need to run.
