I don't think you need to get that complicated. The `Page` model is aware
of all of its `Displayable` children, whether `Link` or 'RichTextPage`.
Your menu should iterate through all of them, going as deep or shallow as
you like.

Entirely possible we're both misunderstanding each other; I'll blame lack
of both cognitive ability and caffeine on this end.

Re: [mezzanine-users] Re: Mezzanine 3.1.10: Can't delete the media files in the admin page

[Simon Bradley]

For anyone else using windows. There was another small issue.

This line in views.py:

# CREATE FILEOBJECT
url_path = "/".join([s.strip("/") for s in
[get_directory(), path, file] if s.strip("/")])

Changed it to:

# CREATE FILEOBJECT
url_path = "/".join([s.strip("/") for s in
[get_directory(), path.replace("\\", "/"), 
file] if s.strip("/")])


This might not be the best way to solve the problem but if you just want to 
get it working on windows it does seem to do the trick.

Re: [mezzanine-users] Need to have the same page in multiple locations in the page tree, how link them?

[Roger van Schie]

Hi Ken

I might be missing your point, or misunderstanding something completely,
but templating is not a problem for me, I've written the models/templates
in such a way, that depending on what information they put into the page,
various parts of the page template get displayed or not, and hence I'm able
to reuse the same template for all levels (which is actually infinite, as
far as mezzanine / django will allow).

All I'm really doing is creating a fancy menu (besides the basic intro's
etc ), displaying the children pages as graphical images, which I propagate
into the template using template tags to pull the hero image's location
instead of just their name. All this works perfectly fine.

I think I will just extend the Page model to include a foreign key, and
then add another check into the template tag to see whether the child page
currently being "inspected" has a foreign key or not, and if it does, just
to go one level deeper to get the info it needs.

Still open to suggestions or corrections.

Thanks
Roger

 Hi Everyone

 I have a use case where the client basically wants a rich text field
 page to write about a certain product, but this product falls under
 different categories. Each category is higher up in the branch hierarchy,
 and they want that same page(the rich text field page) to be displayed in
 multiple categories.

 My current thinking is to just create a custom page model that has a
 foreign key to the other page and put that in the page tree. Would this be
 the best approach?

[Ken Bolton]

Hi Roger,

It is possible to do some terrifying things with the page templates. Read
http://mezzanine.jupo.org/docs/content-architecture.html#page-templates.
(Tortured language in that section is largely my fault, and improvements
are welcome.) I have managed to create "content inheritance trees" across
`Displayable`s by (ab)using the Mezzanine page templates.

A note of caution: a lot of folks think their content and architecture is
unique, a special butterfly that doesn't fit long-established information
architecture patterns. I have yet to find a case where that is true, though
I acknowledge your client may have found it. Often, it only takes careful
management by engineering to help the customer past this.

hth,
ken

Re: [mezzanine-users] Need to have the same page in multiple locations in the page tree, how link them?

[Roger van Schie]

Hi Everyone

As far as I can tell, the "Link" page won't work for me because I pull
information from the child page to display in the parent page. Basically,
my client has different categories, and within those categories they have
sub-categories, and so on, all built using the page tree structure. The
sub-categories are displayed on the category page on a "card", with an
image that is pulled from the sub-category page. I've basically created a
custom menu, where the child pages' display more than just the title.

Would an appropriate approach be to extend the link model to include a
foreign key linking to the actual page? Or should I just extend the Page
model with a foreign key to point to the other page? Anyone got a better
suggestion / solution?

Regards
Roger
