oh, i missed out my def set_pub_date() in views.py.
Here is the revised version of my code: ( link to dpaste is here:
http://dpaste.com/71532/ )
#urls.py
press_detail_dict = {
'queryset': PressRelease.objects.all(),
'template_name':'press/detail.html',
'template_object_name':'press',
}
press_list_dict = {
'queryset': PressRelease.objects.all(),
'template_name':'press/press_list.html',
'allow_empty':False,
'template_object_name':'press',
}
press_create_dict = {
# just a side note: on the template : press_create.html, call the form
just by using {{ form }}
'form_class': PressReleaseCRUD,
'template_name':'press/press_create.html',
'post_save_redirect':'/press/list/',
#'extra_context':{'pub_date': set_pub_date()}
// the above line is commented out bcos is causes an error :
TypeError: set_pub_date() takes exactly 1 argument (0 given)
}
urlpatterns = patterns('',
(r'^detail/(?P<pid>\d+)/$','press.views.detail'),
#using generic views -> list/detail generic views
(r'^list/$', 'django.views.generic.list_detail.object_list',
press_list_dict),
(r'^detail/(?P<object_id>\d+)/$',
'django.views.generic.list_detail.object_list', press_detail_dict),
# testing django.views.generic.create_update.create_object
(r'^create/$', 'django.views.generic.create_update.create_object',
press_create_dict),
#using generic views redirect
#(r'$','django.views.generic.simple.redirect_to',{'url':'/press/
list/'})
)
# views.py
class PressRelease(models.Model):
title = models.CharField(max_length=100)
body = models.TextField()
pub_date = models.DateField()
author = models.CharField(max_length=100)
def __unicode__(self):
return self.title
class PressReleaseCRUD(ModelForm):
class meta:
model = PressRelease
exclude = ['pub_date']
def set_pub_date(request):
if request.method == 'POST':
form = PressReleaseCRUD(request.POST)
if form.is_valid():
new_obj = form.save(commit=False)
new_obj.pub_date = datetime.datetime.today()
new_obj.save()
# press_create.html
<form action="" method="post">
<p>{{ form.as_p }}</p>
<input type="submit" value="Submit" />
</form>
