Re: How to store position of current/active navigation entry

[DJ-Tom]

I now came up with this solution:

path = req.get_full_path()
if path.startswith(entry['href']):
entry['active'] = True

thanks for helping :-)

the nav entry to be highlighted by default is a function of which page is
being viewed.  Further, I presume that you know which page to display
because a GET request was issued (either vanilla or AJAX), and the path
part of the URL (possibly in combination with query parameters, if you have
a truly complex scheme) allows the combination of your urlpatterns and view
functions to know what to render.  It follows (to me, at least) that the
information available in the request is enough to know which item should be
highlighted.

If that's correct, then nclude whatever attribute you need to on a navi
entry object that it can be compared with a value derived from the request
(either in your view, in a template tag, or (best) placed in the context by
a template context processor (still has to be a request context to give you
access to the request object)).  Use this with an "if" tag to control
adding a class to the "li" element (for instance) which, in common with
simple CSS, highlights it.

There are also schemes with mutually unique classes on your "li" elements,
the same, or related, class as for the one to be highlighted on a
containing element, and a set of CSS rules, one for each highlight-able
menu item, to highlight the "li" if the outer class is an ancestor of the
corresponding "LI"'s class.  This is messy, potentially requiring
dynamically generated CSS if your Nav tree changes dynamically.  The use
case is where you are pulling new data through AJAX to morph the page into
a new one, so that a new menu item should be highlighted.  The JavaScript
need only change the class on the outer element, allowing your to to avoid
having to loop across the nav removing the one highlight class (from the
first approach), or from the one that your JavaScript knows was
highlighted, before applying it to the newly selected "li" (mutually unique
classes are still a help to this JavaScript).

There is no usual way to do this because you can have anything behind menu 
item. So here is what I do in the same situations. Let say that we have 
some categories listed in your navi. Every category must have unique ID so 
in navi view pass some variable with that ID for example "foo = entry.pk"

Then in template you can do this
{{ entry.name }}

hope it helps

Re: How to store position of current/active navigation entry

[DJ-Tom]

Hi,

I don't think I know how to actually do what you are suggesting.

Lets say I have three menu options with the following URLS:

"One" - /one/show
"Two" - /two/show
"Three" - /three/show

Currently I have somthing like this in my main.html page template:

{% if navi %}
> {% for entry in navi %}
> {{ entry.name 
> }}
> {% endfor %}
> {%  endif %}
>

With the following view function:

def show_mainPage(request):
>
> navigation = [ {'href':'/one', 'name':"One"},
>{'href':'/two', 'name':"Two"},
>{'href':'/three', 'name':"Three"}]
> return TemplateResponse(request, 'main_page/main.html', {'navi': 
> navigation, 'main_settings':main_settings.objects.get(id=1)})
>

So how would I set the "active" CSS class in my template for the correct 
nav entry?

Re: How to store position of current/active navigation entry

[Bill Freeman]

One traditional place to store navigation state is in the URL.

If you are reloading the page with a new GET (such as because a link was
clicked), you have to indicate what page to load in the URL, whether in the
path or in the parameters.  The view has access to the URL, and uses it to
know where you are in the hierarchy, in turn allowing it to load the
correct page.

But since it knows where you are, it can encode the Nav side bar
accordingly.  (Use RequestContexts in all views and render the Nav with a
template tag in your base template.  The tag can see the request object, so
it knows the path, etc.)  So far this doesn't require any JavaScript.  But
the better Navs can open sub-trees on hover, etc., and that does require
JavaScript, and means that the whole tree is sent every time anyway, with,
for example, CSS classes to control what's highlighted and what's open by
default.

If, on the other hand, you are not reloading the page, but filling in stuff
using AJAX, the AJAX request still has to indicate what is needed.
Probably the JavaScript (required to do AJAX) already knows the new spot in
the hierarchy, and can perform the highlighting.  If not, because, for
instance, information the user entered will be looked up in the database to
determine the place in the hierarchy, the AJAX response must include Nav
information for the AJAX.

But, yes, you can store pretty much anything on the session object.  But
note that this probably does the wrong thing if the user hits back, or uses
a bookmark, or otherwise enters a specific path on your site, since the
information on the session (he gets the same session)  is for where you
thought he was.  Also, suppose he has two windows or tabs of the same
browser open on you site, intending to view separate pages: they use the
same session.

How to store position of current/active navigation entry

[DJ-Tom]

Hi,

I'm currently creating a web app with django that will have a side bar menu 
with several sub-sections.

I'm wondering if there is a "standard" way to store the "current" or 
"active" menu entry so I can highlite it in the menu area each time a 
request takes place.

Is it possible to attach arbitrary information to the current users session 
object?

thanks
thomas
