No puedo soportar su lenguaje de plantillas. Tengo que usarlo?Link to this heading#

\n

Nosotros pensamos que nuestro motor de plantillas es la mejor cosa después de la tocineta en trozos, pero reconocemos que escoger un lenguaje de plantillas es cercano a la religión. No hay nada acerca de Django que requiera usar el lenguaje de plantillas, si estás apegado a Jinja2, Mako, o lo que sea, siéntete libre de usarlos.

¿Tengo que utilizar su modelo/capa de base de datos?Link to this heading#

\n

Nope. Just like the template system, the model/database layer is decoupled from\nthe rest of the framework.

\n

The one exception is: If you use a different database library, you won’t get to\nuse Django’s automatically-generated admin site. That app is coupled to the\nDjango database layer.

¿Cómo uso los campos de imagenes y archivos?Link to this heading#

\n

Utilizar una:class:~django.db.models.FileField o una :class:`~django.db.models.ImageField`en un modelo toma unos pocos pasos:

\n
    \n

  1. In your settings file, you’ll need to define MEDIA_ROOT as\nthe full path to a directory where you’d like Django to store uploaded\nfiles. (For performance, these files are not stored in the database.)\nDefine MEDIA_URL as the base public URL of that directory.\nMake sure that this directory is writable by the Web server’s user\naccount.

    2. \n

  2. Add the FileField or\nImageField to your model, defining the\nupload_to option to specify a\nsubdirectory of MEDIA_ROOT to use for uploaded files.

    3. \n

  3. All that will be stored in your database is a path to the file\n(relative to MEDIA_ROOT). You’ll most likely want to use the\nconvenience url attribute\nprovided by Django. For example, if your\nImageField is called mug_shot, you can get\nthe absolute path to your image in a template with\n{{ object.mug_shot.url }}.

¿Cómo hago que una variable esté disponible en todas mis plantillas?Link to this heading#

\n

Sometimes your templates just all need the same thing. A common example would\nbe dynamically-generated menus. At first glance, it seems logical to simply\nadd a common dictionary to the template context.

\n

La solución correcta es usar un RequestContext. Los detalles de cómo hacer esto están aquí: Subclassing Context: RequestContext.
