Question

I have a function abc in model . i want to call that function abc in controller.

i am new to magento and dnt have any idea regarding this. Can any body tell me how to do this

Answer 1

It's called Magic Function.

$yourModel = Mage::getModel('yourmodulename/yourmodelname')->load($id);

$return = $yourModel->abc();

or you can do

$yourModel = Mage::getSingleton('yourmodulename/yourmodelname')->load($id);

$return = $yourModel->abc();

this is for your reference of getSingleton VS getModel

Answer 2

You can use

Mage::getModel('modulename/modulename')->yourMethod();

Suppose you want catalog category then

Mage::getModel('catalog/category')->load($id);

Answer 3

Suppose your configuration is -

    <models>
        <modulename> <!--  this here is the first part of your getModel() call -->
            <class>Packagename_Modulename_Model</class>
            <resourceModel>modulename_mysql4</resourceModel>
        </modulename>
        <modulename_mysql4>
            <class>Packagename_Modulename_Model_Mysql4</class>
            <entities>
                <abc>
                    <table>table_abc</table>
                </abc>
            </entities>
        </modulename_mysql4>
    </models>

Now you need the second part after the /. If your model name is: Packagename_Modulename_Model_Abc, then you take everything after your prefix, which was defined in the config Packagename_Modulename_Model, lowercase the first character

Now you can access your model following way:

Mage::getModel('modulename/abc')->yourMethod();

Answer 4

If the model lives in a subfolder of your module, you need to load it like:

Mage::getModel('yourmodelname_as_defined_in_config/path_to_file_filename')

Example

Load app/code/local/Aschroder/SMTPPro/Model/Email/Log.php

like Mage::getModel('smtppro/email_log');
