I'm trying to build a list of replicable fields where the order can be interchanged.
To do so I've built three different models Multicap Multitext Multimg which are Inlines of the model Multis which is an Inline of the model Delta.
I'm using django-nested-admin and everything works fine on the admin page, I can add new objects and change their order.
The problem I have is that when I populate the fields, save the model and then check its content, all the data of the text fields are turned into zeros 0.
instead, when I try to save the image I get this error:
AttributeError: 'int' object has no attribute 'field'
models.py

name = models.TextField(max_length=50, null=True, blank=True)

ordering = ('name',)
def __str__(self):
return str(self.name)

caption = models.TextField(max_length=50, null=True, blank=True)
