I've localized my site following the documentation.
Now, I've wanted to test this through the browser. But, I seem not to be able to figure out how this is done.
I am using FF and in preference / content / languages, added 'es'. I also moved it to the top of the languages list.
Then when I go to the site, I don't see anything translated.
What am I missing?
Thanks

Django stores the language code in the cookie for each user. You'll probably want to make use of Django's set_language view, perhaps at least in your development environment, because it's quicker than deleting cookie entries or destroying sessions. I used it to write a custom view that switches between the base language and another one to snoop through the site just to be 100% sure I'm translating everything.
If that still doesn't work, might want to make sure you've added it to the list of LANGUAGES and that you've added the django.middleware.locale.LocaleMiddleware to your list of middleware, because it's responsible for parsing Accept-Language from request headers.

I have a fairly large django project consisting of several individual apps. I am farming out some of the front-end work (CSS, HTML tweaks) to people who aren't over-familiar with django. To that end I'd like to generate a list of templates for each URL pattern any given engineer is working on. This will save much time that would otherwise be spent manually tracking down the templates used during a view's render phase.
For example, if Bob is working on URLs beginning with /accounts/ then I'd like to generate a list of all the templates used by any view that handles requests to those URLs.
My initial thought is to use something in the test framework since that has access to the templates rendered during a request. However, I can't guarantee that all URLs or views will be exercised (sadly I don't have 100% test coverage), and a missed template is unlikely to be noticed. I don't mind writing a set of tests that simply exercise each view, but don't want to duplicate existing efforts. Also certain views require POSTed data or authentication to function correctly - although I suspect that's an issue I'll have to face no matter what approach is used.
Are there any utilities or snippets that will do what I need?
django-debug-toolbar is a must for developing with Django, It includes a panel detailing all templates used during a request.
I've found the SQL panel is the most helpful for improving page load times as it details slow and duplicate queries.
It can slow down requests when enabled, disabling all panels but those that you use helps.
I have just learnt about Django apps. I want to know that within one site, if I make different apps. like, users, profiles, polls, blogs,comments, jobs , applications then how can I manage them to make them intereactive? And is it how the concept of app should be? I want to have things loosely coupled that's why asking? Rails work on the way of REST, so do Django support that also with the use of apps? May be my questions seems a bit ambiguous because I am new to django and some of my concepts are still messed up.
Please tell what ever you know.
The general idea is that apps should be as loosely coupled as possible. The goal is to have completely self-contained functionality. Now, of course, that's not always possible and many times it even makes sense to bring in functionality from another app. To do that, you simply import whatever you need. For example, if your "blogs" app needed to work with your Comment model in your "comments" app you'd simply add the following to the top of the python file you're working in:
from comments.models import Comment
You can then use Comment as if it were defined right in the same file.
As far as REST goes, Django's views are much more fluid. You can name your view whatever you like; you need only hook it up to the right urlpattern in urls.py. Django views can return any content type, you just prepare the response and tell it what mimetype to serve it as (the default is HTML).
I am working on a Django application which is going to be deployed to Heroku (on their Cedar stack). A limitation of this is that we cannot write to disk. However, Django translations reside in .po files, and therefore the client will be unable to change the translations on the live site without involving a developer (which is not ideal).
The alternative solution therefore seems to be to store the translations in either an RDBMS, Mongo, Redis etc etc.
Is there any sensible way of achieving this? Is it even a good idea? (I wouldn't want to hit the DB for every translation!)
Edit: There seem to be lots of Django apps out there for translating text which is stored in a DB, but not for actually storing the translations themselves in a DB.
What I think about Django translations and translations stored in the files in general - this is for the parts which will not change and is not dynamic. Like constants you have in the website. And if you have dynamic text, which could be and must be edited when the website is running - I would say this is the same thing as normal content (blog entry, comments and so on).
So you can just develop simple module "site parts", with the template tag, which will grab the right thing for you from DB. Like from template you can call { get_site_part example }. And then you can edit those parts from admin interface.
I would not recommend to store dynamic content to the system files. If you worry about hitting database every time you need this - then caching should help here also you can develop smart template tag and grab all the site parts you need in one query. Then it will be nothing different from just simply loading blog entry or the comment for it.
Maybe I'm wrong, so this is just my 2c on this topic :)

A company I'm looking at claims to have made the website for an airline and a furniture store using Django, but when I look at the sites, there is no indication what the underlying web technology is. How can you tell?
This is quite an old question, but I don't see any canonical answers. As the other answers have noted though, there's no sure-fire way to know, and if someone wanted to hide the fact that they're using Django, they can. That said, you can always do a little detective-work and determine with some confidence whether it uses Django or not. If that's your goal, here are some strong indicators you can look out for:
Admin Panel
First and foremost, check if the site has a /admin/ page. If it does, and it gives that familiar Django admin login page, you're 99% sure (unless someone went through a lot of trouble to make it look like Django).
Forms
There are a number of things you can look out for in forms:
Form fields with id attributes starting with id_
Check for a hidden field with the name csrfmiddlewaretoken
If the site has a formset, check for -TOTAL-FORMS and -DELETE hidden inputs.
Cookies
If the site uses the contrib.auth package for authentication, you will probably see a cookie called sessionid being set when you log in.
Forms will also probably set a cookie called csrftoken.
Trailing Slashes
Trailing slashes after URLs, and/or redirecting you to the page with a trailing slash if you try to go to one without it. This is Django's default behavior, and to my knowledge not extremely common in other frameworks. Note, though, that it can be easily deactivated in Django.
Error Pages
Failing all this, or still not being convinced, you can try to force error pages, and try to learn something from that. Go to an unmapped URL with a 404 page, and see if DEBUG still happens to be true (in which case you should probably notify the owner that they're not being very secure about their site).
You can try a few things, such as attempting to find error pages, and checking the default location of the administration panel that Django creates, but overall there's no way to determine what technologies a given site is using.

Look for the csrf input box. This is present on any forms. But this can be turned off though not very recommended. Also if it's an old version of django this may not exist. But if it's there it's a strong indicator.
This is present on any page that have a post form. And it looks like this:
<input type='hidden' name='csrfmiddlewaretoken' value='3b3975ab79cec7ac3a2b9adaccff7572' />
Navigate to a page with a formset, and check if there are *-TOTAL_FORMS or *-DELETE hidden inputs.
That doesn't prove that they are using Django, but might be a clue that they are (with the mentioned model formsets).
Try to navigate to some 404 error page, or something of that sort. Chances are slim, but try to find a default django error page.
You can also try to login to www.website.com/admin and see if you get the default django admin page.
Other than that, if that didn't work, then you just can't.
There are no reliable indicators to my knowledge but you could check the /admin/ URL to see if you get the standard admin app or sometimes the feed-URLs use a common prefix compared to a common suffix (although this might not be an indicator at all but just a preference of the developers).
Trying to trigger a debug page (either via a 404 or using some broken input that might case an internal error) might also be a good way (although this acts more as a test of competency of the original developers and admin than anything else :-) )
Could you ask the airline and / or the furniture store? I'm guessing that you want to know if this company has good experience in django, I think it is reasonable to ask for references if you are considering working with them.
The other companies may be quite happy to discuss what technologies were used - some are and some aren't, but it's worth asking.
I'm developing a blog application using Django. Currently, the URL /blog/ displays the front page of the blog (the first five posts). Visitors can then browse or "page through" the blog entries. This portion is mapped to /blog/browse/{page}/, where page, of course, is an integer that specifies which "page" of blog entries should be displayed.
It's occurred to me, though, that perhaps the "page number" should be an attribute of the querystring instead (e.g., /blog/browse/?page=2), since the content of the browse pages is not static (i.e., as soon as I add another post, /blog/browse/2/ will have different contents than it had before the post was added). This seems to be the way sites like Stack Overflow and Reddit do things. For example, when paging through questions on Stack Overflow, a "page" attribute is used; likewise, Reddit uses a "count" attribute.
Extending this thinking, I realize that I use the same template to render the contents of both /blog/ and /blog/browse/, so it might even make sense to just use a URL like /blog/?page=2 to page through the contents of the blog.
Any suggestions? Is there a "standard" way of doing this, or at least a "best practice" method to use?
For my money, the best general purpose approach to this issue is to use the django-pagination utility. It's incredibly easy to use and your URLs should have the format you desire.
I prefer to use the GET URL parameter, as in URL?pg=#. It's very common and provides a standard visual clue to users about what is going on. If, for instance, I want to bookmark one of those pages or make an external link, I know without thinking that I can drop the pg parameter to point at the "latest" front-page index. With an embedded #, this isn't as obvious... do I leave off the parameter? Do I always have to set it to 1? Is it a different base URL entirely? To me, having pagination through the GET parameter makes for a slightly more sensible URL, since there's an acceptable default if the parameter is omitted and the parameter doesn't affect the base URL.
Also, while I can't prove it, it gives me the warm fuzzy feeling that Google has a better chance at figuring out the nature of that page's content (i.e. that it is a paginated index into further data, and will potentially update frequently) versus a page # embedded inside the URL, which will be more opaque.
That said, I'd say this is 99% personal preference and I highly doubt there's any real functional difference, so go with whatever is easier for and fits in better with your current way of doing things.
EDIT: Forgot to mention that my opinion is Django specific... I have a few Django apps so I'm relatively familiar with the way they build their URLs, and I still use a "pg" GET parameter with those apps rather than embedding it in the URL directly.
It seems like there are two things going on. A static page, that won't change and can be used for permalinking, like an article, as well as a dynamic page that will update frequently. There is no reason you cannot use both. URL rewriting should allow this to work quite nicely. There's no reason to let the implementation control the interface, there is always at least one way to skin every cat.
