Of course form does not have access to the object. But you can pass
some value which is accessible in view from view to form.
Separating task in 2 parts :
1) set initial values in view class
class myviewclass():
""" This is example only . full class realization is more complex """
form_class = myformclass
template_name = "mytemplate.html"
get_initial(self):
""" Passing initial values to the form"""
# At first initial data should be saved
super(myviewclass, self).get_initial()
# adding our value
self.initial= {"myuser": self.request.user}
return self.initial
Second part (form side)
myformclass():
""" This is really simple example. Perfect form is more complex"""
def __init__(self, *args, **kwargs):
# get our values from view
myvalues = kwargs.pop('initial', None)
#print it to console (this is a dict by default)
print myvalues
# and executing default constructor after this
super(myformclass, self).__init__(*args, **kwargs)
