    <p>I'm new to pyramid as well as the traversal concept. I have a basic object model working with traversal however the objects are location un-aware, so reading up on pyramid documentation found on this page <a href="http://docs.pylonsproject.org/projects/pyramid/en/1.0-branch/narr/resources.html#location-aware" rel="nofollow">http://docs.pylonsproject.org/projects/pyramid/en/1.0-branch/narr/resources.html#location-aware</a> it talks about using the pyramid_traversalwrapper. </p> <p>Following the instruction I added the following lines to my main:</p> <pre><code>config = Configurator(root_factory=Root) config.registry.registerAdapter(ModelGraphTraverser, (Interface,), ITraverser) </code></pre> <p>The rest of my traversal tree objects look like this:</p> <pre><code>class Root(object): def __init__(self, request): pass def __getitem__(self, key): if key == 'users': return UserList() raise KeyError class UserList(): def __getitem__(self, key): users = {'a':None,'b':None, 'c':None} if key in users: return User() raise KeyError class User(object): def __init__(self): pass def __getitem__(self, key): if (key == 'channels'): return Channels() def GET(self): return Response("got user") </code></pre> <p>When I ran the code it does seem to use the ModelGraphTraverser when resolving urls, however what do I have to do to make my model location-aware, as in knowing the <code>__parent__</code> and <code>__name__</code> and such? Do I have to add wrapper classes? If so how do I go about doing it? pyramid_traversalwrapper is supposed to make managing <code>__parent__</code> and <code>__name__</code> effortless, but I have no idea how to take advantage of it.</p>

    1. COLocation-awareness of objects matters for security and generating urls, but not for matching of URLs. Can you explain or show what you are trying to do with location-aware objects? pyramid_traversalwrapper only solves certain use-cases.

    2. COBut what if I just want to know where I came from? Like let's say if I have have two urls /user/super/permissions, and /user/public/permissions, so depending on how I arrived at the permissions module, I want the module to do different things?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
