Building a Retail Application

It’s not the intent that normal unprivileged users of an application you build using Substance D ever see the SDI management interface. That interface is reserved for privileged users, like you and your staff.

To build a “retail” application, you just use normal Pyramid view configuration to associate objects with view logic based on the content types provided to you by Substance D and the content types you’ve defined.

For example, here’s a view that will respond on the root Substance D object and return its SDI title:

1
2
3
4
5
6
7
from pyramid.view import view_config

@view_config(content_type='Root')
def hello(request):
    html = u'<html><head></head><body>Hello from %s!</body></html>'
    request.response.text = html % request.context.sdi_title
    return request.response

Note that we did not use the substanced.sdi.mgmt_view decorator. Instead we used the pyramid.view.view_config decorator, which will expose the view to normal site visitors, not just those visiting the resource via the SDI.

To see that code working, create a retail package within the myproj package (that is the inner myproj folder that contains the __init__.py, resources.py and views.py files). The package will have two files: an empty __init__.py and a views.py with the code snippet above. If you now visit http://localhost:6543/ you will see the “Hello from…” message.

To display actual content stored in the database, Substance D exposes a resource tree that you can hang views from to build your application. You’ll want to read up on traversal to understand how to associate view configuration with resource objects.
