How to set the unit layout attributes? - magento

Question

I'm writing a module for magento 1.9. Help please set the attributes for the
app/design/frontend/rwd/default/layout/kalinin_form.xml:
<?xml version="1.0" ?>
<layout>
<kalininform_index_index>
<reference name="content">
<block type="kalininform/form" template="Kalinin_Form/index.phtml" />
</reference>
</kalininform_index_index>
</layout>
I now have the type attribute set to false.
The problem is that the browser displays a blank page with the content area on localhost/magento3/index.php/form
Here is the rest of the code of the module.
app/design/frontend/rwd/default/template/Kalinin_Form/index.phtml:
<?php
echo('qqqqqqqqqqqqq');
app/code/local/Kalinin/Form/controllers/IndexController.php:
<?php
class Kalinin_Form_IndexController extends Mage_Core_Controller_Front_Action
{
public function indexAction()
{
$this->loadLayout();
$this->renderLayout();
}
}
app/code/local/Kalinin/Form/Block/Form.php:
<?php
class Kalinin_Form_Block_Form extends Mage_Core_Block_Template
{
public function getNewsCollection()
{
Mage::log("Your Log Message");
return true;
}
}
app/code/local/Kalinin/Form/etc/config.xml:
<?xml version="1.0" ?>
<config>
<modules>
<Kalinin_Form>
<version>0.0.1</version>
</Kalinin_Form>
</modules>
<frontend>
<layout>
<updates>
<kalininform>
<file>kalinin_form.xml</file>
</kalininform>
</updates>
</layout>
<routers>
<kalininform>
<use>standard</use>
<args>
<module>Kalinin_Form</module>
<frontName>form</frontName>
</args>
</kalininform>
</routers>
</frontend>
<global>
<blocks>
<Kalinin_Form>
<class>Kalinin_Form_Block</class>
</Kalinin_Form>
</blocks>
</global>
</config>
In general, I have a problem with understanding the attributes into app/design/frontend/rwd/default/layout/kalinin_form.xml
Official documentation is not present. I would be grateful if you explain what's what.

In your app/design/frontend/rwd/default/layout/kalinin_form.xml file, your block attribute type value is wrong. it should be kalinin_form/form.
<?xml version="1.0" ?>
<layout>
<kalininform_index_index>
<reference name="content">
<block type="kalinin_form/form" template="Kalinin_Form/index.phtml" />
</reference>
</kalininform_index_index>
</layout>
Value of type attribute should be matched with blockgroup_name given in config.xml.
Please see, your block group name is Kalinin_Form
<global>
<blocks>
<Kalinin_Form>
<class>Kalinin_Form_Block</class>
</Kalinin_Form>
</blocks>
</global>
