Hi,
I have a problem calling manage.py syncdb for my models.
Here is my models:
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class DocumentType(models.Model):
name = models.CharField(max_length=20, unique=True)
description = models.CharField(max_length=200)
assignedType = models.ForeignKey('self')
class Category(models.Model):
name = models.CharField(max_length=20, unique=True)
type = DocumentType()
relatedCategories = models.ForeignKey('self',
related_name='relatedCategories')
description = models.CharField(max_length=200)
class Document(models.Model):
type = DocumentType()
viewed = models.PositiveIntegerField(max_length=7)
#rating =
#ranking =
created_by = User()
changed_by = User()
created_at = models.DateTimeField()
changed_at = models.DateTimeField()
categories = models.ManyToManyField(Category,
related_name='categories') #n to m relationship
assignedDocuments = models.ForeignKey('self',
related_name='assignedDocuments')
parentDocument = models.ForeignKey('self',
related_name='parentDocument') #1 to n relationship
The error that I got is:
Error: One or more models did not validate:
common.category: Accessor for field 'relatedCategories' clashes with field
'Category.relatedCategories'. Add a related_name argument to the definition
for 'relatedCategories'.
common.category: Reverse query name for field 'relatedCategories' clashes
with field 'Category.relatedCategories'. Add a related_name argument to the
definition for 'relatedCategories'.
common.document: Accessor for field 'assignedDocuments' clashes with field
'Document.assignedDocuments'. Add a related_name argument to the definition
for 'assignedDocuments'.
common.document: Reverse query name for field 'assignedDocuments' clashes
with field 'Document.assignedDocuments'. Add a related_name argument to the
definition for 'assignedDocuments'.
common.document: Accessor for field 'parentDocument' clashes with field
'Document.parentDocument'. Add a related_name argument to the definition for
'parentDocument'.
common.document: Reverse query name for field 'parentDocument' clashes with
field 'Document.parentDocument'. Add a related_name argument to the
definition for 'parentDocument'.
What is wrong with my model.

Steve
