Backend Development
To modify the backend, we need to create a new scope in our configuration file called
admin. Perform the following steps to do so:
1. Open the config.xml file, which can be found at the location app/code/
loca/Mdg/Giftregistry/etc/.
2. Add the following code to it:
admin
Mdg_Giftregistry_Adminhmtl
giftregistry
This code is very similar to the one we used before to specify our frontend route;
however, by declaring the route this way we are breaking an unwritten Magento
design pattern.
In order to keep things consistent on the backend, all new modules should extend
the main admin route.
Instead of defining the route with the previous code, we are creating a completely
new admin route. Normally, you don't want to do this for the Magento backend
unless you are creating a new route that requires admin access but not the rest of the
Magento backend. A callback URL for an admin action would be a good example of
something like this.
Fortunately, there is a very easy way to share route names among Magento modules.
Sharing route names was introduced in Magento 1.3
but to this day, we still see extensions that don't use this
pattern properly.
