Magento 1.9 : Error getting collection Model of Catalogrule

Question

I try to get a collection of Mage::getModel('catalogrule/rule') but when I do Mage::getModel('catalogrule/rule')->getCollection() I have an error because can't call a function of boolean.

I do a if:

if(Mage::getModel('catalogrule/rule')) echo "hello"; else echo "no";

Always say "no".

Answer 1

Use below code:

$rules = Mage::getModel('catalogrule/rule')->getCollection()->addFieldToFilter('is_active', 1);

if($rules): 
    echo "hello"; 
else: 
    echo "no";
endif;

Answer 2

Working code:

$catalogrules = Mage::getModel('catalogrule/rule')->getCollection()->addFieldToFilter('is_active', 1);

foreach($catalogrules as $rule){
    echo '<pre>'; 
    print_r($rule->getData());
    echo '</pre>';
}

if(count($catalogrules)>0){
   echo "hello"; 
}
else{
   echo "no"; 
}

You will get all active catalogPrice rules with rules data.

Answer 3

First, try have you got class?

 echo get_class(Mage::getModel('catalogrule/rule'));die;

if you got empty value your module is inactive.

Please, active your Module:-

app/etc/modules/Mage_All.xml

is your module

Mage_CatalogRule

is <active>true</active> ?

OR

System > Configuration > Advanced > Disable modules output

Check your module is active?
