definition path to shipping model when create custom shipping method

Question

Have problem with creating custom shipping method. When new module for shipping method is active then checkout process stop after insert shipping details. No shipping methods shows up either checkout proccess stopped. I think my problem is in definition path to shipping model in my config.xml. Please see my config.xml below. Actually path to model is \app\code\local\Devpassion\Osobno\Model\Carrier\Osobno.php.

<?xml version="1.0"?>
<config>
<modules>
    <Devpassion_Osobno>
        <version>0.1.0</version>
    </Devpassion_Osobno>
</modules>
<global>
    <models>
        <devpassionosobno>
            <class>Devpassion_Osobno_Model</class>
        </devpassionosobno>
    </models>
    <resources>
        <devpassionosobno_setup>
            <setup>
                <module>Devpassion_Osobno</module>
            </setup>
        <connection>
            <use>core_setup</use>
        </connection>
        </devpassionosobno_setup>
    </resources>
</global>
<default>
    <carriers>
        <devpassionosobno>
                <active>1</active>
                <model>Devpassion_Osobno/carrier_osobno</model>
                <name>Devpass Osobno</name>
                <title>Osobno preuzimanje</title>
        </devpassionosobno>
    </carriers>
</default>

Answer 1

I think the carrier definition should look like this

<default>
    <carriers>
        <devpassionosobno>
                <active>1</active>
                <model>devpassionosobno/carrier_osobno</model>
                <name>Devpass Osobno</name>
                <title>Osobno preuzimanje</title>
        </devpassionosobno>
    </carriers>
</default>

Also make sure that the model devpassionosobno/carrier_osobno (Devpassion_Osobno_Model_Carrier_Osobno) exists and is a valid shipping carrier. I mean check if it extends Mage_Shipping_Model_Carrier_Abstract or a child of this class and it should implement Mage_Shipping_Model_Carrier_Interface. Turn on your error logging and you should be able to see the errors in var/log.

Answer 2

I figured out and this is definition of path that works for me. Home someone find this answer useful:

 <default>
  <carriers>
   <osobnopr>
       <active>1</active>
       <model>ship/carrier_osobnopr</model>
       <title>Carrier Title</title>
       <name>Method Name</name>
       <price>5.00</price>
   </osobnopr>
 </carriers>

I that definition "osobnopr" is name of shipping model. And full path to that model is \app\code\local\Devpassion\Ship\Model\Carrier\Osobnopr.php
