Can't make block and model rewrite working

Question

I am getting mental break because I can't make my custom module which should rewrite 2 blocks and 1 model work. My module is loaded - I checked in admin panel System->Configuration->Advanced but Magento still reads core files. Overmore, I am trying to rewrite reviews form so when I am in admin panel watching reviews and make intentional mistake in name of class in Acme_Reviewed_Block_Adminhtml_Review_Edit_Form I get blank screen so it looks like it is reading my blocks and models. Maybe I made a mistake somewhere which I can't find.

Answer 1

Finally, I resolved this riddle. My code is example how much traps are waiting for unexperienced developer. I made 3 mistakes.

1. Acme/Reviewed/Block/Adminhtml/Review/Edit/Form.php

Whole code of extended function is taken from core file Mage_Adminhtml_Block_Review_Edit_Form which I extend. I just added a simple changes. So at the end of function is line:

return parent::_prepareForm();

But the problem is Mage_Adminhtml_Block_Review_Edit_Form which I extend also extends other file Mage_Adminhtml_Block_Widget_Form.

So in my file 'parent' means Mage_Adminhtml_Block_Review_Edit_Form but in the core it stands for return Mage_Adminhtml_Block_Widget_Form

I had to change this line to this and works perfect:

return Mage_Adminhtml_Block_Widget_Form::_prepareForm();

2. Acme/Reviewed/Model/Resource/Review.php

I wrote config well, but for extending model, not for extending model resource. So when I changed config.xml to the code below it is working well also.

<review_resource>
    <rewrite>
        <review>Acme_Reviewed_Model_Resource_Review</resource_review>
    </rewrite>
</review_resource>

3. Acme_Reviewed_Block_Reviews

So here I wanted to extend function which was located in Magpleasure_Ajaxreviews_Block_Reviews, but I didn't notice that it is not the end of 'extending chain'. I found that the last file which extends Magpleasure_Ajaxreviews_Block_Reviews is Magpleasure_Ajaxreviews_Block_Placing_Additional so I had to extend this class with my changed function.
