Chapter 5
On the __construct function, we are specifying a few important options about our
grid class. We are setting the gridId; the default sort to be by eventDate, and we are
enabling pagination and filtering.
The __prepareCollection() function loads a collection of registries filtered by
current customerId. This function can be used to do more complex operations in our
collection too; for example, joining a secondary table to get more information about
the customer or another related record.
Finally, by using the __prepareColumns() function, we are telling Magento which
columns and attributes for our data collection should be shown and how we can
render them.
Now that we have created a functional grid block, we would need to do some
changes to our layout XML file in order to display it. Perform the following steps:
1. Open the giftregistry.xml file, which can be found at the location app/
design/adminhtml/default/default/layout/.
2. Make the following changes:
mdg_giftregistry
mdg_giftregistry/adminhtml_customer_
edit_tab_giftregistry
