Can I have a Django model that has a foreign key reference to itself?

I want to implement a simple folder-file like structure in my Django app. So I have a model for storing folders, but I also would like to store relation between this folder and parent folder. The simplified version of model would look like following:

class mFolder(models.Model):
    name = models.CharField(max_length=50)
    parentFolder = models.ForeignKey(mFolder, unique=False, related_name="childrenFolders")

However this is not possible, beacause mFolder is not declared yet.

Is there any simple solution for that problem?

Thanks for your help in advance.

Answer 1

Should be 'self':

parentFolder = models.ForeignKey('self', unique=False, related_name="childrenFolders")
