Redirection issue using PK - django

Question

I Have a very strange phenomenon
In my app the user Create a project and is redirected to that project detail using its pk. On that project detail page he is asked to create a team and when the team is created he is redirected again to the project detail page but to the wrong pk
for example: I just created a project and I got redirected to .../project/24. I was asked to create a team, I created it but got redirected to ../project/17 any idea why and how to redirect my page to the right URL ?
model.py:
class Team(models.Model):
team_name = models.CharField(max_length=100, default = '')
team_hr_admin = models.ForeignKey(MyUser, blank=True, null=True)
def get_absolute_url(self):
return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk})
def __str__(self):
return self.team_name
class TeamMember(models.Model):
user = models.ForeignKey(MyUser)
team = models.ForeignKey(Team)
def __str__(self):
return self.user.first_name
class Project(models.Model):
name = models.CharField(max_length=250)
team_id = models.ForeignKey(Team, blank=True, null=True)
project_hr_admin = models.ForeignKey(MyUser, blank=True, null=True)
def get_absolute_url(self):
return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk})
def __str__(self):
return self.name
views.py
class TeamCreate(CreateView):
model = Team
fields = ['team_name']
template_name = 'team_form.html'
def form_valid(self, form):
valid = super(TeamCreate, self).form_valid(form)
form.instance.team_hr_admin = self.request.user
obj = form.save()
#SELECT * FROM project WHERE user = 'current_user' AND team_id = NULL
obj2 = Project.objects.get(project_hr_admin=self.request.user, team_id=None)
obj2.team_id = obj
obj2.save()
return valid
return super(TeamCreate, self).form_valid(form)
def get_success_url(self):
project = Project.objects.get(team_id=self.obj, project_hr_admin=self.request.user)
return project.get_absolute_url()

Answer 1

The problem here is your CreateView is refering to a TeamObject and not project.
You should override the get_success_url method:
def get_success_url(self):
project = Porject.objects.get(team_id=self.object, project_hr_admin=self.request.user)
return project.get_absolute_url()
The function called was the get_absolute_url of your Team model. So you're calling the project detail view but with the team pk => you get a random project assuming there's a project with a pk which has the same value as your project or, the pk you're sending doesn't exist and you'll have a 404 error (pk doesn't exist).
def get_absolute_url(self):
return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk})
That's the one in your Team model, but you call ProjectDetails. So here, self.pk is Teaminstance.pk.
What I do in the code i gave you is to call the get_absolute_url of the project instance.
But as told in the other answer, you should remove or change your get_absolute_url of your team model.

Answer 2

class Team(models.Model):
# ...
def get_absolute_url(self):
return reverse('website:ProjectDetails', kwargs = {'pk' : self.pk})
^^^^^^^
Here, the wrong pk will be delived. Thx to #Bestasttung for clarification
