The way to do that is to use the 'initial' keyword argument when you
instantiate the form, to which you supply a dictionary of field name :
initial value e.g.:
form = KingModelForm(initial={'first': 'First Name', 'last': 'Surname'})
How you split the name will depend on how you're storing it. Assuming
you have the name in "First Names Surname" format, this should do it:
def split_name(name):
"""Return a dictionary of first and last names from the given name."""
splitname = name.split() # splits on white space
last = splitname[-1]
first_names = splitname[:-1] # Allows for more than one first name
first = ' '.join(first_names)
return dict(first=first, last=last)
Then:
form = KingModelForm(initial=split_name(name))
Just a thought, is there any reason not to store first and last as
separate fields, and join the names when you present them on screen / in
reports? That would save having to make assumptions about the number of
first and surnames people enter (someone could enter 'Barton Hartley' as
a double-barreled surname for example).

I like to set the value/s of a field in a form before displaying it.
A rather silly example (to illustrate the principle) :
class King(models.Model):
name = models.CharField(max_length=250, blank=False)
class KingModelForm ( forms.ModelForm ):
first = forms.CharField( label = 'Foo', required=True)
last = forms.CharField( label = 'Foo', required=True)
I need to split the name field up and allocate it to first & last
before displaying the form for editing.
(When saving the form, these values will be combined, but that
part can be done via the save_form() method.)
Any help with this is appreciated.
Thanks
Derek
