As there can be 20 or more images associated with a system, This is
more what I was looking for. Thanks!!!
However, I can't seem to get this to work.
Here are the new lines in System:
def get_header_pic(self):
return
self.system_pictures.filter(image_category__name='Header_Pic')
def get_header_logo(self):
return
self.system_pictures.filter(image_category__name='Header_Logo')
I put them just above the Class Admin: line.
Here is the new lines in the template:
<IMG src="{{ info.get_header_pic.location }}"
width="{{ info.get_header_pic.width }}"
height="{{ info.get_header_pic.height }}" border="0"
name="{{ info.get_header_pic.name }}">
<IMG src="{{ info.get_header_logo.location }}"
width="{{ info.get_header_logo.width }}"
height="{{ info.get_header_logo.height }}" border="0"
name="{{ info.get_header_logo.name }}">
