Hi,
Thank you very much for the great module. This helped me a lot. Can you help me to create more sub menus under Twits tab? I create two sub menus. Don’t know how to do rest. Actually don’t know how to load different layouts for them. Please help me.

Thanks in advance.

Thnak you! I was struggling with a grid whos collection had a join which resulted in an ambigous column in the where clause. While not directly addressing this issue your example used the “filter_index” property which was exactly what I was looking for!

Hi 23, what you're looking for is relatively tricky i assume. Magento's way of piecing the Sales Orders and Invoices together is quite complicated. I have not dived that deep into the models manipulation yet so i'm uncertain how to do the advanced grouping/reporting required. But it should be doable. Where possible you'll have to learn to work with the model's collection and filters, then go the rest of the way by your own calculations. =) For example you can get a collection of sales invoices, filter them by date, then add up the totals together. to get your periodic revenue, then go into the items to calculate the periodic cost and finally get the profit. Sounds easier than it really its. =p

hey gaweee -
thanks for your advices. my problem is that I can not find the depending collection.php or the place where I have to put the code in. I am also not able to find a fitting sql query, which I can manipulate like “SELECT ‘cost’ FROM …” or how to accumulate the costs over a specific time (i.e. monthly costs / profit) and calculate the periodic profit.

I expect that I am too dumb to understand the needed framework and programming knowledge.
gaweee – do you have a donate-button somewhere on your page and 10mins time?
regards.

Hey 23,
There are some events of a Grid that gets triggered after loading the Collection _afterLoad or something. you can always override those methods and manipulate the Model‘s Collection into the Grid‘s data. then point the right Index there. But that’s a really dirty way to do it.

The right way is to use Grid Filters and Renderers. Example:

getValue();
		return array('like'=>'%'.$this->_escapeValue($value).'%');
	}
}

As well as

getRequest_path();
		$sefurl = Mage::helper('twit/data')->removePrefix($sefurl,  Mage::getStoreConfig('twit/seo/some_url_prefix'));
		$sefurl = Mage::helper('twit/data')->removeSuffix($sefurl,  Mage::getStoreConfig('twit/seo/some_url_suffix'));
 
		return $sefurl;
	}
}

Then you can add the column in the Grid this way:

	$this->addColumn('request_path', array(
            'header'        => Mage::helper('twit')->__('URL'),
            'align'         => 'left',
            'width'         => '150px',
            'filter_index'  => 'request_path',
            'index'         => 'request_path',
            'type'          => 'text',
            'filter'		=> 'twit/some_module_main_grid_filter_url',
            'renderer'  	=> 'twit/some_module_main_grid_renderer_url',
            'escape'        => true,
        ));

Hi – Thanks a lot for your awesome howtos! Nice job!

My question is the following:
I try to expand the sales report by two columns in order to show the cost and calculate the net profit.
The changes in the app/code/local/mage/adminhtml/block/report/sales/sales/grid.php worked well.
I added the following lines:

$this->addColumn(‘cost’, array(
‘header’ => Mage::helper(‘sales’)->__(‘cost’),
‘index’ => ‘cost’,
‘type’ =>’currency’
));

$this->addColumn(‘profit’, array(
‘header’ => Mage::helper(‘sales’)->__(‘net profit’),
‘index’ => ‘shipping_description’ //shipping_discription for testing purposes
));

I would like to know which entries for ‘index’ are available in this report and how to expand the corresponding collection.php to fetch the product relevant costs and calculate the net profit and paste it in a var.

Maybe somebody would help me
Kind Regards,
23

I got an error while filtering results.
Removing prefix “dt.” in filter_index’s value of $this->addColumn solved the problem.
