Silverstripe-使模块从自定义页面类型扩展的最佳方法

Question

My site structure is all custom page types with a single parent page the extends from Page.php.

class CustomPage extends Page {}

class  Custom_Controller extends Page_Controller {
    //load all javascript/css for entire site here etc
}


class SomeClass extends CustomPage {}

class SomeClass_Controller extends Custom_Controller
{
    // etc etc you get the point. 
}

Every other page in the site now extends from CustomPage and Custom_Controller respectively. Page.php is pretty much empty.

Now the problem comes when using modules that are not written internally. The Blog* module for example will not inherit the javascripts/css/functions defined in the new base class Custom_Controller as it is set to extend Page_Controller.

What is the ideal method here for basically making Blog_Controller extend Custom_Controller without modifying the Blog module?

*Blog module is just an example. this applies to all modules.

The short answer to the direct question

What is the ideal method here for basically making Blog_Controller extend Custom_Controller without modifying the Blog module?

is that it's not technically possible to do. Effectively you've got two options;

1. Make your changes to the Page/Page_Controller classes directly
2. Inherit Page/Page_Controller in your custom page types, but rather than modifying Page directly, use an extension that is bound to Page to provide the custom behaviour for all sub-page types. For the specific case of providing custom init() behaviour, you'll want a custom extension that extends the Extension class, and is bound to Page_Controller
