Hi i did a component

on the model i have models/experiment_type.php
class RmnmanagementCkModelExperimenttype extends RmnmanagementClassModelList
{
.....
code
....
protected function prepareQuery(&$query)
{
... code ...
}

...
}

I want to make some changes, thus i go to _fork/models/experiment_type.php
class RmnmanagementModelExperimenttype extends RmnmanagementCkModelExperimenttype
{

/**
* Preparation of the list query.
*
* @access protected
* @param object &$query returns a filled query object.
* @return void
*/
protected function prepareQuery(&$query)
{
echo 'a';die;
}
}

and it does nothing !!
why??

Did you copy the model from the _fork directory to the fork directory?

i just copied the function

protected function prepareQuery(&$query)
{
echo 'a';die;
}

Sorry, I wasn't very clear

The file experiment_type.php needs to be in the directory fork/models, i.e. copy it from _fork

_fork contains the base files for forking but that directory is not used at runtime, the fork directory is where the code looks for overrides

Documentation for the forks :

Also, you must respect the fork location (front or back)
