Well, at this point it is up to you to determine the absolute url of
each object. Since we don't know what fields your model has, and what
views are supposed to serve it, we can't say for sure what the url
should be.
In general, all objects inheriting from Displayable will have a slug
field, which is ideal for generating urls. In that case,
get_absolute_url() can return reverse("your_url_name", kwargs={"slug":
self.slug}).
Of course, for this to work you'll need to create the view that serves
the object and register it under a named urlpattern.

OK, I've gotten more done after watching your video and going over the

admin.site.register(ProjectLinkPage)

So now "Project links" appears in the admin page lefthand side. When I
add a new project link, then try to view it on site, I get an error
saying:

NotImplementedError: The model ProjectLinkPage does not have
get_absolute_url defined

I will add a `get_absolute_url()` method to my `ProjectLinkPage`
class. But here's the thing. I want this Projects Page to have links
to different, customized pages. One of the links on the Projects Page
could go to an HTML file that has an interactive map on it. Looking at
`get_absolute_url()` in Mezzanine's BlogPost class, I'm unsure how I'd
edit ProjectLinksPage's `get_absolute_url()` to do what I want. Any
tips? Examples of other custom-made `get_absolute_url()` methods? Or
maybe I'm looking at this all wrong?

Hi Tom.
You need to register your model in the admin. You can use
mezzanine.blog.admin as an example:
https://github.com/stephenmcd/mezzanine/blob/master/mezzanine/blog/admin.py
<https://github.com/stephenmcd/mezzanine/blob/master/mezzanine/blog/admin.py>.
This admin configuration is a bit complex, so I recommend you
become familiar with Django's admin in general before diving into
it. Have you completed the official Django tutorial? It should
introduce you to all these concepts:
https://docs.djangoproject.com/en/1.11/intro/tutorial01/

Hey all,
When I go to the Admin section of my site, I see the "Blog
posts" under "Content" on the left. I want to make a new
"Content" section called "Projects." It would be similar to a
page of blog posts. But I'm not sure how to start doing this.
Here's what my app's `models.py` looks like.

I basically copied a section of `mezzanine/blog/models.py`.
But "Projects" won't show up in my Admin menu. What am I doing
wrong?
