django NOT NULL fehlgeschlagen Fehler

Question

ich einen Fehler in der Form django.db.utils.IntegrityError habe: NOT NULL fehlgeschlagen:

in meiner app frage ich den Benutzer ein neues Projekt zu erstellen, und dann fragen über ein Formular, um den Namen des Teammitglieds hinzuzufügen. Wenn die E-Mail bereits in der Datenbank vorhanden ist, wird der Benutzer per E-Mail zur Anmeldung bei der App eingeladen. Wenn die E-Mail nicht in der Datenbank vorhanden ist, wird der Benutzer per E-Mail zur Anmeldung aufgefordert Das eingeladene Mitglied wird dem Team hinzugefügt.

ich diese Störung erhalte, wenn Sie einen vorhandenen Benutzer in der Datenbank

hier zuweisen möchten, ist mein Code:

def TeamRegister2(request): 
    #import pdb; pdb.set_trace() 
    InviteFormSet = formset_factory(InviteForm2) 

    if request.method == 'POST': 
     formset = InviteFormSet(request.POST) 

     if(formset.is_valid()): 
      for i in formset: 
       mail = i.cleaned_data['Email'] 
       if MyUser.objects.filter(email = mail).exists(): 
        user = MyUser(email = mail) 
        u1 = user.id # get user ID 
        a1 = MyUser.objects.get(email = request.user.email) #get user email 
        a2 = Project.objects.filter(project_hr_admin = a1) #get all project created by the user 
        a3 = a2.latest('id') # extract the last project 
        a4 = a3.team_id # extract the team linked to the project 
        a4.members.add(u1) # add the member to the team 

        invited_user = MyUser.objects.get(email = mail) 
        current_site = get_current_site(request)

        to_email = mail

      print("The entered form is not valid") 

    else: 
     formset = InviteFormSet() 
    return render(request,'team_register.html', {'formset':formset}) 

MyUser Modell:

class MyUser(AbstractBaseUser): 
    email = models.EmailField(

     unique=True,

    is_hr = models.BooleanField(default=False) 
    is_candidate = models.BooleanField(default=False) 
    is_employee = models.BooleanField(default=False) 
    company = models.CharField(max_length=100, blank=True, null=True) 

Team Modell:

class Team(models.Model): 
    team_name = models.CharField(max_length=100, default = '') 
    team_hr_admin = models.ForeignKey(MyUser, blank=True, null=True) 
    members = models.ManyToManyField(MyUser, related_name="members") 

def __str__(self): 
    return self.team_name 

Projekt Modelle:

class Project(models.Model): 
    name = models.CharField(max_length=250) 
    team_id = models.ForeignKey(Team, blank=True, null=True) 
    project_hr_admin = models.ForeignKey('registration.MyUser', blank=True, null=True) 
    candidat_answers = models.ManyToManyField('survey.response') 

eine Ahnung, wie diese Fehler zu beheben und den Benutzer zum Team hinzu? thx Sie;)

Answer 1

Sie versuchen, eine nicht gespeicherte MyUser Instanz mit dem ManyToMany Feld hinzuzufügen. Sie müssen das Objekt abrufen, anstatt ein neues Objekt zu erstellen.

user = MyUser.objects.get(email=mail) 
a4.members.add(user)
