How do I make django translate certain files? - django

I'm running django-admin.py makemessages -l es from within my app directory to create trnaslation strings. The result includes only those texts that are located in my app directory. My templates directory to that app is located outside the app's directory. How do I ask django to translate my template files too?
I didn't want to run the above command from within the project's dir, because my project contains certain folders that I do not want to translate.

Never mind, I found the answer. You have to create symlinks to the folders you want to get translated (i.e. templaets) and copy those symlinks to you apps directory and run the above command with --symlinks included.

If i understand correctly you'll need to use django's trans and blocktrans
template tags to translate certain strings of text.

How to package an OpenStack Horizon Dashboard plugin correctly?

I am packaging a Horizon Plugin. I have a bunch of templates, a view, as well as css, js files, and images.
Everything should be contained so that the package is either a .deb or a tarball. So right now I keep all files in /opt/stack/horizon/openstack_dashboard/dashboards/<my-dashboard-name>.
My question is, how do I include js and css files properly? There is /opt/stack/horizon/openstack_dashboard/settings.py file that specifies HORIZON_CONFIG.js_files, however it is always empty! I put a list of files there, it still comes out as empty in the templates. So the question is, how do I include js and css files in a Horizon dashboard plugin, for the purpose of packaging it in either a single tarball or a .deb package?
You should store static files below <my-dashboard-name>/static. It's best to namespace your static files, I use the following directory structure:
<my-dashboard-name>/static/<my-dashboard-name>/js and so on for css and img then I reference the files in the HTML templates with /static/<my-dashboard-name>/js/jsfile.js, that way you won't get any name collisions.
When someone uses your plugin they extract your dashboard and register it in the right places and then additionally they have to run the collectstatic django management command from the base openstack_dashboard directory (in your case /opt/stack/horizon/), either:
$ ./run_tests.sh -m collectstatic
or
$ ./manage.py collectstatic
That should copy your static files to the right places according to how the site has been configured.

In Django (v1.6.5), what's the best practice for location of Templates, Static files?

I am severely confused about where to put my templates files and static files.
I understand absolute and relative paths just fine, but I can't seem to find any instructions that mirror the installation I have. I know this resembles other questions, but those answers aren't working. The video I watched to successfully build a simple app didn't put templates in the Project folder, which is where logic tells me they should be.
I have Python at:
C:\Python27
Django (v1.6.5) at:
C:\Python27\Lib\site-packages\django
I created a project "mysite" and an app called "films."
Project "mysite":
C:\Python27\Scripts\venv\mysite
and an App "films":
C:\Python27\Scripts\venv\mysite\films
The video I watched had me put my templates at:
C:\Python27\Lib\site-packages\django\contrib\admin\templates
But this seems completely stupid because the templates are outside of both the Project and the App.
Shouldn't I put a templates folder in the Project folder:
C:\Python27\Scripts\venv\mysite\templates
And then create subdirectories using the App name?
What files do I need to edit (and how) to tell Django where to find them?
Follow a similar process for static files (css, images)?
Like all frameworks, django offers great benefits if you follow some guidelines (and give up some control). The trick is to know what these guidelines are.
For templates:
If the template is not tied to a particular application, put it in a templates directory at the root of your project. Add the full path to this directory to TEMPLATE_DIRS.
All other templates should go in a directory called templates inside your application directory. So if you application is called myapp, templates for myapp will go in myapp/templates/
For static files:
For files related to specific applications, inside your application directory create a directory called static, then inside it a directory with the name of your application. So, if your application is called myapp, you would have myapp/static/myapp. Place all your static content for this application here; for example myapp/static/myapp/js/funky.js.
For static files that are generic, create a directory called assets (or static) in the root directory of your project. Add the full path to this directory to STATICFILES_DIRS.
By default, django will search all applications listed in INSTALLED_APPS, and add any templates and static directories to its search path for files. This is how, by default, the admin works without you having to configure anything.
If you chose to place your templates and static files in some other location, only then do you need to modify the TEMPLATE_DIRS and STATICFILES_DIRS settings. If all your templates and static assets are tied to applications, just creating the directories as mentioned above makes everything work.
If you are wondering why you need to create another directory under myapp/static/ to store your static files, this is more for portability. The collectstatic command is a simply "copy and replace" utility. It will overwrite all files in the STATIC_DIR location. This means that if two applications have some static file with the same name, they will be overwritten without warning. Adding a subdirectory keeps your application's static assets from being overwritten, because the exact path will be created.
Suppose you have two applications, app1 and app2, and both have a file named style.css in their respected directories:
app1/static/css/style.css
app2/static/css/style.css
When you run collectstatic, you'll end up with the following (assuming static is the name of your STATIC_DIR setting):
static/css/style.css
This may be the style.css from app1 or app2, the other cannot be determined (its actually based on the INSTALLED_APPS order). To prevent this, if you have:
app1/static/app1/css/style.css
app2/static/app2/css/style.css
Now, you'll end up with:
static/app1/css/style.css
static/app2/css/style.css
Both files will be preserved.
You also shouldn't put your code in your virtual environment directory. The virtual environment is not part of your source code, and placing your project in the same directory may cause problems later.
Create a single directory for your environments - I call mine envs (creative, I know). Create all your environments in this directory. Once you activate the environment, you can work in any directory in your system and your shell will be configured for that environment's Python.
Finally for the best, accurate, most up-to-date information - always refer to the django manual and the tutorial. Almost all other resources (even the often suggested djangobook.com) are outdated.

Which Django internationalization files are being used?

I can switch languages in my Django application by changing LANGUAGE_CODE in the Settings.py file for the application.
But I'm not sure where the actual text is coming from.
In path-to-django/contrib/auth/locale/, there are directories for many languages containing the translations of the text I'm displaying. But if I move an .mo file for a particular language to a new name, I still see text for that language -- even after I restart Django. So where does the text actually come from?
Also, for the 'en' locale, the translated text is always "" (empty string). Does ugettext_lazy just return its input string in that case? If not, where does the English text come from?
It is a difference, if you speak of translation in the django admin or within your application. The path you mentioned .../contrib/auth/locale refers to translations in the django admin.
For special translation within your application you should have a locale/ folder in your project. This folder is created when you run the django special script named "django-admin.py makemessages".
The script runs over your project source tree or your application
source tree and pulls out all strings marked for translation. It
creates (or updates) a message file in the directory
locale/LANG/LC_MESSAGES. In the de example, the file will be
locale/de/LC_MESSAGES/django.po.
For detailed explanation, please look at django i18n documentation
After you have created your message files (*.po) and after you have written your own translations in the message files, don't forget to compile them:
Compiling message files
After you create your message file -- and each
time you make changes to it -- you'll need to compile it into a more
efficient form, for use by gettext. Do this with the django-admin.py
compilemessages utility.
This tool runs over all available .po files and creates .mo files,
which are binary files optimized for use by gettext. In the same
directory from which you ran django-admin.py makemessages, run
django-admin.py compilemessages like this:
django-admin.py compilemessages
That's it. Your translations are ready for use.
It turns out there was a system-wide Django installation that was being used, rather than my local installation.
By creating a locale directory within my app, I'm able to override the strings used in the system-wide installation. I just modify the .po file there, and compile it.

Why doesn't Django produce locale files from template files in another directory?

Version info:
Django version 1.3 pre-alpha SVN-13858
Ubuntu GNU/Linux 10.10
I'm totally new to i18n and l10n in Django and currently I'm trying to make my Django project available in Dutch (in addition to its default language: English). I tried to apply the instructions given at http://docs.djangoproject.com/en/dev/topics/i18n/translation/ and http://www.djangobook.com/en/2.0/chapter19/ but I had no success. I don't know if this is related to my directory structure and template files being in a completely different directory (I mean not as a subdirectory within the my Django project directory). My project directory looks like the following:
/home/emre/mydjango/myproject
/home/emre/mydjango/myproject/myapp1
/home/emre/mydjangotemplates
/home/emre/mydjangotemplates/myapp1
In the myproject and myapp1 directories I tried to issue the following command:
django-admin.py makemessages -l nl
But received the following error:
Error: This script should be run from the Django SVN tree or your project or
app tree. If you did indeed run it from the SVN checkout or your project or
application, maybe you are just missing the conf/locale (in the django tree)
or locale (for project and application) directory? It is not created automatically,
you have to create it by hand if you want to enable i18n for your project or
application.
So I tried to create locale directories within myproject and myapp1 directories. After that I issued the above command again (once in the project and once in the app directory) and this time without any error or warnings it said:
processing language nl
I checked the locale directories and saw that they were populated with sub-directories but there weren't any .po files at all:
$ tree
.
`-- nl
`-- LC_MESSAGES
2 directories, 0 files
I double checked that I have my .html files (template files) in home/emre/mydjangotemplates and that they include {% load i18n %} and some lines like {% trans "A piece of English text" %}.
What am I missing? Should I invoke the django-admin.py makemessages command with different parameters? Why doesn't Django create .po files even though I have some text to be translated in my .html template files?
makemessages only looks in directories under the current directory. You can try creating a symlink from somewhere under your project to your templates directory and add the -s to make it follow symlinks.

Django: Internationalization, makemessages doesn't create po files

I have an application located in one folder, and templates for it in another one...
I have added translation strings to the templates (which are stored in templates directory, I have one directory for all templates in my application)
When I go to the application folder and run a script there:
silver:articles oleg$ django-admin.py makemessages -l ru
processing language ru silver:articles
oleg$
I am getting empty
silver:articles oleg$ ls locale/ru/LC_MESSAGES/
silver:articles oleg$
And when I am running this command for example in project root, I am getting po file full made from python files (which seems strange to me because I thought it should be created from htmls)
makemessages always looks for strings marked for translation in python code files.
except for that, it looks in all .html files. maybe your templates have another extension? If that's the case you can use -e to specify other extension:
django-admin.py makemessages -l=ru -e=html,htm,txt
