I think that the user who made this comment
(https://code.djangoproject.com/ticket/25905#comment:8) makes a valid
point.
This is an important issue because currently, it doesn't allow to serve as
default an static file (this is useful for example when setting a default
avatar image in a user models, and in many others use's cases, as it allow
to have many objects referencing the same file, instead of each one of
them having a copy)
In development, where is a common practice to have the media and static
folders in the root of the project, this is easily solved by doing:
{{{
avatar = ImageField(default="../static/default_avatar.png", blank=True).
}}}
But what about production, when you usually serve your static files from a
CND or solucions like AWS S3 ???
The best solution I've come up with so far is to allow that field to be
null, and explicitly right the get method of that field:
{{{
avatar = ImageField(blank=True, null=true)
def get_avatar(self):
# variable PATH_TO_DEFAULT_STATIC_IMAGE depends on the enviroment
# on development, it would be something like
"localhost:8000/static/default_avatar.png"
# on production, it would be something like
"https://BUCKET_NAME.s3.amazonaws.com/static/default_avatar.png";
return self.avatar if self.avatar else <PATH_TO_DEFAULT_STATIC_IMAGE>
}}}
However, it does look a little bit over-engineer, considering that most of
the time, the default is an static file.
