Re: who is 'Cake' : some basic oop cake nonunderstanding
Hi Ken. It did help. my main problems were revolving around data handling between different classes (of models controllers). If you created have the instances yourself (written the code that does ..) you know how they can handle data to some other instance. i just couldnt get my head around the queer syntax, and it wasnt obvious to me that a controller can call its model method to call another models method with data just being transferred in arrays as simple as can be, really. Now i understand the syntax (a tiny bit at least) and can keep learning. I see lots of requireAction discussions, and they might be the result of the same, very basic, problem, on how to move data around without having to go via the view - even though request action will do just that, and even a complete newbie like me can see thats stupid. so. thx again --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups CakePHP group.

Re: who is 'Cake' : some basic oop cake nonunderstanding
Yes, CakePHP explanations can be terse. However, there is a description of how a CakePHP app gets started in section one of the manual (see: http://book.cakephp.org/view/10/Understanding-Model-View-Controller). 1. Where are the objects ?? I see lots of classes but no instances of them.Yes, there is '$this', but it doesnt count since its a reference to an actual object, which, as far as i could see in all the tutorials, doesnt exist yet. It all starts with the Dispatcher. An instance of the Dispatcher gets created near the end of /app/webroot/index.php. From there, the app follows the conventions of CakePHP to know that the controller that it needs to create an instance of is contained in the URL. That's why URLs are in the form /app_name/controller_name/action/arguments. The instantiation of the controller class by the Dispatcher results in the instantiation of other classes like Helpers, Models, Components, etc. Some are instantiated by default, other you define with member variables like $uses and $helpers. The code that actually instantiates these classes is in the core CakePHP libraries. You don't really need to know the guts but the code is all there to follow if you want. The power if CakePHP is that you don't have to write a bunch of code to do things like instantiate classes, do input validation, render output etc.. Instead you follow the conventions and CakePHP library classes and methods do the trudgery. It is important to know the general control flow of CakePHP so you understand why functions like beforeFilter() and beforeRender() exist and why you would use them. Check out: http://book.cakephp.org/view/21/A-Typical-CakePHP-Request 2. I see of a static parent::method and variable, i see variables that are handled via arrays, but where are object references ?? As said in anohter post $this-Model-find IS a reference to am instantiated class. You define this either by following the convention and creating a Model class or by adding a model name to $uses. Again, the CakePHP libraries just follow the conventions to instantiate the classes you tel it to. 3. also havent come across a protected method in any tutorial yet. Why is that - just by chance ? or did i not look well enough. That's PHP4 syntax (as in another post). So. In order to use the structure it is essential to know whats actually going on. 'sentences like 'cake' does this or that dont help, btw. escpecially since i have no clue who the hell 'cake' is :). CakePHP is an instance of and MVC framework. Period. You might want to read up on what MVC is some more. Try: http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller Then again -there's nothing like experience - so, go through the motions, follow the conventions, implement a simple app or two or three and you will learn a bunch.

who is 'Cake' : some basic oop cake nonunderstanding
only got into baking very recently, and while there are lots of promises how 'supersimple' everything is with cake i still havent found the most basic fundamentals of how its actually working. is there anybody who can answer these simple questions - they would help me getting a long way into actually really using cake instead of just pasting modifying codesnippets from other sources : 1. Where are the objects ?? I see lots of classes but no instances of them.Yes, there is '$this', but it doesnt count since its a reference to an actual object, which, as far as i could see in all the tutorials, doesnt exist yet. 2. I see of a static parent::method and variable, i see variables that are handled via arrays, but where are object references ?? 3. also havent come across a protected method in any tutorial yet.

'sentences like 'cake' does this or that dont help, btw. escpecially since i have no clue who the hell 'cake' is :). I hope that these questions are easily answered in no cookbook style :) The cookbook is going into details of functionality before the basic structure is clarified. It repeats itself with cake makes this and that easy for you, but what i a always missing, is : how, does cake do it. Yes the codesnippets are easy, yes the conventions are great, yes the MVC structure is cool, and yes i'm sure cake can do it. Is there a reference maybe, or a clear and simple model of how it does these things, so that beginners with cake dont need to try and make 'cake' do things in ways that it wasnt designed for ?

There are object refs all over the place! Start with dispatcher.php
and follow from there.
3. also havent come across a protected method in any tutorial yet.

Because CakePHP supports PHP4.x the public/private/protected keywords
are not used. A protected method or variable will be prefixed by a
single underscore ('_') and a private one with two ('__').
So. In order to use the structure it is essential to know whats
actually going on. 'sentences like 'cake' does this or that dont help,
btw. escpecially since i have no clue who the hell 'cake' is :).
CakePHP is a framework. If someone says that it does something it
means, this is how it works.
I agree that Cake is a bit difficult to follow, especially when first
diving into it. I'm sure there is documentation out there somewhere
that runs through a complete and *detailed* example of a request but
I've never seen it. Perhaps somebody else can post a link.
I hope that these questions are easily answered in no cookbook
style :)

Re: who is 'Cake' : some basic oop cake nonunderstanding
Objects are used everywhere. What do you think your doing in a
controller when you access models or components?
$this-Component-method();
Take a look at Auth, it references the Controller object as well as
modifies it.
