I have been playing with Django for only a day or so but have had great
success coercing a legacy database into the Django world. I have
quickly found that the Admin interface *nearly* provides all the
editing features I currently need for updating my DB and I think it
would be a great shame to leave my current 'no code' model to add the
few extra features I need in views/templates. I am hoping that the
community might be able to help me out with my three questions:
1) Menu item ordering
class Iconography(meta.Model):
description = meta.CharField(maxlength=255)
def __repr__(self):
return self.description
class META:
admin = meta.Admin(
ordering = ('description',),
)
class Light(meta.Model):
window = meta.ForeignKey(Window, edit_inline=meta.TABULAR)
sub_location = meta.CharField(maxlength=255, core=True)
iconography = meta.ForeignKey(Iconography)
class META:
admin = meta.Admin()
The 'ordering' works as expected when looking at the Iconography table,
but when viewing a Light, the 'select' widget shows the Iconography's
in (I guess) ID order. Is it possible to sort this menu?
2) Ordering on foreign key field
class Window(meta.Model):
building = meta.ForeignKey(Building, edit_inline=meta.TABULAR)
reference = meta.CharField(maxlength=255, core=True)
location = meta.ForeignKey(Location)
def __repr__(self):
return "%s / W%s / %s" % (self.get_building().principal_name,
self.reference, self.get_location())
class META:
admin = meta.Admin(
ordering = ('reference',), # FIXME sort on building name too
)
Is it possible to sort this Window table on the principal_name of the
building referred to and then the Window's own reference (effectively
sorted on the __repr__ I have written).
3) Linking to another table
class Building(meta.Model):
"""Building table."""
.....
class Window(meta.Model):
building = meta.ForeignKey(Building, edit_inline=meta.TABULAR)
......
class Light(meta.Model):
window = meta.ForeignKey(Window, edit_inline=meta.TABULAR)
......
Opening an entry in the Window table correcly shows all Lights. Opening
an entry in the Building table correctly shows all Windows, but it does
not show all the subsequent Lights. In practice I don't want to as
there are too many, but is it possible to add links in the inline
Windows to open the relevant Window table?
I could obviously do all of these things by writing a custom view, but
I don't want to embark on coding if I've just missed some simple
tricks. Any Help / guidance greatfully received.
