Working with FileFields/FieldFiles

[Hugo Kitano]

Hi, I'm a beginner with Django, and I'm trying to figure out how to work with FieldFiles.

One of my models has a FileField in which the user must submit a .bed file.  I use another library in python to analyze the .bed file.
The .bed file is saved to a specific directory on disk, and I want

file_on_disk = Bed('/Users/.../media/statistics.bed')

where statistics.bed is the name of the file, and media is the directory all files are saved to.  How would I construct this line of code?

Thanks!

You're probably after the upload_to argument of FileField, which let you define where files are saved:

 

    https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.FileField.upload_to

 

(I assume you're already looked into MEDIA_ROOT):

I guess my question is more "dumb" than that.  I need a concatenated string "ab" where a is given and b is the name of a file uploaded to a field in a model.

 

Thanks!

 

Something like this?

 

    class Blah(models.Model):

        def upload_to(self, filename="untitled", instance=None):

            return "somestring" + filename

 

        data = FileField(upload_to=upload_to)
