Comment:
I applied 3288_96.diff with no effect. My model is:
class ProjectImage(models.Model):
project = models.ForeignKey("Project", null=True, edit_inline=True,
core=True)
title = models.CharField(maxlength=50, blank=True)
description = models.TextField(blank=True)
image = models.ImageField(upload_to='project', height_field="100",
width_field="100", blank=False)
faqs = models.ManyToManyField(Faq, blank=True)
categories = models.ManyToManyField(Category)
class Project(models.Model):
title = models.CharField(maxlength=50)
description = models.TextField()
pub_date = models.DateTimeField(auto_now_add=True)
icon = models.ForeignKey(ProjectImage, edit_inline=True, core=True,
related_name='icon')
parts = models.ManyToManyField(Part)
cars = models.ManyToManyField(Car)
faqs = models.ManyToManyField(Faq, blank=True)
The patch does not break any functionality but I still encounter the same
error.
