How to save user from non class based view in django? - django

Question

I am trying to create new users to the admin and to the app from NON Classe Based View in my django project, I have the model, the view and the template where I am getting the form as it goes in the next code I´m going to show..
models.py
class Users(models.Model):
# Fields
username = models.CharField(max_length=255, blank=True, null=True)
password = models.CharField(max_length=12, blank=True, null=True)
organization_id = models.ForeignKey('ip_cam.Organizations', editable=True, null=True, blank=True)
slug = extension_fields.AutoSlugField(populate_from='created', blank=True)
created = models.DateTimeField(auto_now_add=True, editable=False)
last_updated = models.DateTimeField(auto_now=True, editable=False)
# Relationship Fields
user_id = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True)
class Meta:
ordering = ('-created',)
def __str__(self):
return u'%s' % self.user_id
def get_absolute_url(self):
return reverse('ip_cam_users_detail', args=(self.slug,))
def get_update_url(self):
return reverse('ip_cam_users_update', args=(self.slug,))
def __unicode__(self): # __str__
self.organization_id=self.request.POST.get('organization_id')
return unicode(self.user_id, self.organization_id)
# This overrides the standard save method for a user, creating a new user in the admin and getting it to the template at the same time
def save(self, *args, **kwargs):
self.password = make_password(self.password)
self.user_id, created = User.objects.get_or_create(username=self.username, password=self.password, is_staff=True)
self.user_id.groups.add(Group.objects.get(name='admin'))
self.id = self.user_id.id
super(Users, self).save(*args, **kwargs)
views.py
def UsersCreate(request):
model = Users
var = {}
var = user_group_validation(request)
userInc = Users.objects.get(id=request.user.id).organization_id.pk
request.session['userInc'] = userInc
if var['group'] == 'superuser':
object_list = Users.objects.all()
organization = Organizations.objects.all()
roles_choice = DefaultLandingPage.objects.all()
if var['group'] == 'admin' or var['group'] == 'user':
object_list = Users.objects.filter(organization_id=request.session['userInc'])
organization = Organizations.objects.filter(id=request.session['userInc'])
roles_choice = DefaultLandingPage.objects.exclude(role=1)
url = request.session['url']
tpl = var['tpl']
role = var['group']
organization_inc = Organizations.objects.filter(id=request.session['userInc'])
template = get_template(app+u'/users_form.html')
return HttpResponse(template.render(locals()))
the problem in here is that the save is not working when trying to override it, user is not created at all... can you please help me to see what am I doing wrong this time ? thanks in advance.

If you are not using the generic django class based views, you will have to implement the request's POST and GET functionality yourself. The easiest is to create a form from your user model and handle the request based on whether it's a POST request type or not.
Try this:
forms.py (https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/)
from django.forms import ModelForm
from .models import User
class UserForm(ModelForm):
class Meta:
model = Users
fields = ['username', 'organization_id']
views.py
from .models import User
from .forms import UserForm
def UsersCreate(request):
# This function can hadle both the retrieval of the view, as well as the submission of the form on the view.
if request.method == 'POST':
form = UserForm(request.POST, request.FILES)
if form.is_valid():
form.save() # This will save the user.
# Add the user's role in the User Role table below?
#
else:
# The form should be passed through. This will be processed when the form is submitted on client side via this functions "if request.method == 'POST'" branch.
form = UserForm()
var = user_group_validation(request)
userInc = Users.objects.get(id=request.user.id).organization_id.pk
request.session['userInc'] = userInc
if var['group'] == 'superuser':
object_list = Users.objects.all()
organization = Organizations.objects.all()
roles_choice = DefaultLandingPage.objects.all()
if var['group'] == 'admin' or var['group'] == 'user':
object_list = Users.objects.filter(organization_id=request.session['userInc'])
organization = Organizations.objects.filter(id=request.session['userInc'])
# The line below will ensure that the the dropdown values generated from the template will be filtered by the 'request.session['userInc']'
form.organisation_id.queryset = organization
roles_choice = DefaultLandingPage.objects.exclude(role=1)
url = request.session['url']
tpl = var['tpl']
role = var['group']
organization_inc = Organizations.objects.filter(id=request.session['userInc'])
template = get_template(app+u'/users_form.html')
return HttpResponse(template.render(locals()))
In your app+u'/users_form.html' file, you can access the UserForm fields as follows:
<!-- inside your <form> tag add: -->>
{{ form.username }}
{{ form.organisation_id }}
I haven't tested this code but this should get you on the right track.
