Django FileField default file

Question

I have a model which contains FileField as below

class Employer(models.Model):
        logo = models.FileField(storage=FileSystemStorage(location=settings.MEDIA_ROOT), upload_to='logos')

The question is how can I add a default file like "{{ MEDIA_ROOT}}/logos/anonymous.jpg" to this filefield ?

Solution

You can specify the default file to use for that field as follows:

class Employer(models.Model):
        logo = models.FileField(storage=FileSystemStorage(location=settings.MEDIA_ROOT), upload_to='logos', default='settings.MEDIA_ROOT/logos/anonymous.jpg')

how does the default parameter settings.MEDIA_ROOT get interpolated to the proper value in the string?

[Pedro Muñoz]

the path django is going to use in default is (by default): settings.MEDIA_ROOT + '/' + 'your_path', so be sure you place your default file there

Don't think this solution scales across environments? If the production instance runs S3, for example, does something like MEDIA_ROOT work? And I think the hardcoded FileSystemStorage also doesn't work.
