Ok, I'm just getting back to a project I had to put on hold for a
while.
I recently read an article on problems new Django users fall into, and
I think I hit one.
The bottom of my 'Systems' model looks like this:
keyboard = models.CharField(max_length=80)
cart = models.CharField(max_length=80)
ram = models.CharField(max_length=40)
rom = models.CharField(max_length=40)
media = models.CharField(max_length=80)
options = models.CharField(max_length=120)
quick = models.TextField()
info = models.TextField()
system_pictures = models.ManyToManyField('Image')
public = models.BooleanField()
def __unicode__(self):
return self.name
def get_header_pic(self):
return
self.system_pictures.filter(image_category__name='Header_Pic')[0]
def get_header_logo(self):
return
self.system_pictures.filter(image_category__name='Header_Logo')[0]
The problem is that when using the admin to enter the data for the
Systems, I get a list of every pic in the 'Image' model to choose
from.
I can see this getting frustrating very fast.
I'm thinking that I can just use the fields in the 'Image' model to
find the appropriate pics, but don't know how to re-structure
'get_header_pic' to work with that. Or should I be doing something
different in the View or Template to access these pics?
Also, I added and 'Thumb' model when I added functionality I hadn't
originally though of. Unfortunately, it's almost an exact copy of the
"Image' model I made.
As seen here:
class Image(models.Model):
name = models.CharField(max_length=80)
slug = models.CharField(max_length=80)
location = models.URLField()
height = models.IntegerField()
width = models.IntegerField()
image_category = models.ForeignKey('ImageCat')
info = models.TextField()
primary = models.BooleanField()
def __unicode__(self):
return self.name
class Thumb(models.Model):
name = models.CharField(max_length=80)
slug = models.CharField(max_length=80)
location = models.URLField()
height = models.IntegerField()
width = models.IntegerField()
system = models.ForeignKey('System')
image_category = models.ForeignKey('ImageCat')
big = models.ForeignKey('Image')
primary = models.BooleanField()
def __unicode__(self):
return self.name
I'm thinking I should merge them by adding t_height, t_width and
t_location to the 'Image' model. Am I missing any downside to doing
this?
