# Zarządzanie plikami statycznymi (np. zdjęcia, JavaScript, CSS)

Strony internetowe na ogół wymagają serwowania dodatkowych plików takich jak zdjęcia, skrypty JavaScript lub style CSS. W Django nazywamy te pliki „plikami statycznymi”. _Django zapewnia `django.contrib.staticfiles`, aby ułatwić zarządzanie nimi.

Ta strona opisuje jak możesz serwować te pliki statyczne.

## Konfigurowanie plików statycznych

1. Make sure that `django.contrib.staticfiles` is included in your `INSTALLED_APPS`.

2. In your settings file, define `STATIC_URL`, for example:

       STATIC_URL = '/static/'

3. In your templates, use the `static` template tag to build the URL for the given relative path using the configured `STATICFILES_STORAGE`.

       {% load static %}
       <img src="{% static 'my_app/example.jpg' %}" alt="My image">

4. Store your static files in a folder called `static` in your app. For example `my_app/static/my_app/example.jpg`.

Serwowanie plików

In addition to these configuration steps, you’ll also need to actually serve the static files.

During development, if you use `django.contrib.staticfiles`, this will be done automatically by `runserver` when `DEBUG` is set to `True` (see `django.contrib.staticfiles.views.serve()`).

Ta metoda jest skrajnie nieefektywna i prawdopodobnie niebezpieczna, więc jest nieodpowiednia do celów produkcyjnych,

Your project will probably also have static assets that aren’t tied to a particular app. In addition to using a `static/` directory inside your apps, you can define a list of directories (`STATICFILES_DIRS`) in your settings file where Django will also look for static files. For example:

    STATICFILES_DIRS = [
        BASE_DIR / "static",
        '/var/www/static/',
    ]

See the documentation for the `STATICFILES_FINDERS` setting for details on how `staticfiles` finds your files.

Przestrzeń nazw plików statycznych

Now we might be able to get away with putting our static files directly in `my_app/static/` (rather than creating another `my_app` subdirectory), but it would actually be a bad idea. Django will use the first static file it finds whose name matches, and if you had a static file with the same name in a different application, Django would be unable to distinguish between them. We need to be able to point Django at the right one, and the best way to ensure this is by namespacing them. That is, by putting those static files inside another directory named for the application itself.

You can namespace static assets in `STATICFILES_DIRS` by specifying prefixes.

## Serwowanie plików statycznych podczas rozwoju projektu

If you use `django.contrib.staticfiles` as explained above, `runserver` will do this automatically when `DEBUG` is set to `True`. If you don’t have `django.contrib.staticfiles` in `INSTALLED_APPS`, you can still manually serve static files using the `django.views.static.serve()` view.

For example, if your `STATIC_URL` is defined as `/static/`, you can do this by adding the following snippet to your urls.py:

    from django.conf import settings
    from django.conf.urls.static import static

    urlpatterns = [
        # ... the rest of your URLconf goes here ...
    ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

Informacja

This helper function works only in debug mode and only if the given prefix is local (e.g. `/static/`) and not a URL (e.g. `http://static.example.com/`).

Also this helper function only serves the actual `STATIC_ROOT` folder; it doesn’t perform static files discovery like `django.contrib.staticfiles`.

During development, you can serve user-uploaded media files from `MEDIA_ROOT` using the `django.views.static.serve()` view.

For example, if your `MEDIA_URL` is defined as `/media/`, you can do this by adding the following snippet to your `ROOT_URLCONF`:

    from django.conf import settings
    from django.conf.urls.static import static

    urlpatterns = [
        # ... the rest of your URLconf goes here ...
    ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Informacja

This helper function works only in debug mode and only if the given prefix is local (e.g. `/media/`) and not a URL (e.g. `http://media.example.com/`).

## Testowanie

When running tests that use actual HTTP requests instead of the built-in testing client (i.e. when using the built-in `LiveServerTestCase`) the static assets need to be served along the rest of the content so the test environment reproduces the real one as faithfully as possible, but `LiveServerTestCase` has only very basic static file-serving functionality: It doesn’t know about the finders feature of the `staticfiles` application and assumes the static content has already been collected under `STATIC_ROOT`.

Because of this, `staticfiles` ships its own `django.contrib.staticfiles.testing.StaticLiveServerTestCase`, a subclass of the built-in one that has the ability to transparently serve all the assets during execution of these tests in a way very similar to what we get at development time with `DEBUG = True`, i.e. without having to collect them using `collectstatic` first.

## Wdrażanie

`django.contrib.staticfiles` provides a convenience management command for gathering static files in a single directory so you can serve them easily.

1. Set the `STATIC_ROOT` setting to the directory from which you’d like to serve these files, for example:

       STATIC_ROOT = "/var/www/example.com/static/"

2. Wykonaj polecenie `collectstatic`:

       $ python manage.py collectstatic

   This will copy all files from your static folders into the `STATIC_ROOT` directory.

3. Use a web server of your choice to serve the files. Wdrażanie plików statycznych covers some common deployment strategies for static files.
