I'm trying to add team to the database but i get this error. Took a look at similar questions but none of them solved my issue. (I am new with Django)
My code looks like:
forms.py
from django.forms import ModelForm
from .models import Team
class TeamForm(ModelForm):
class Meta:
model = Team
fields = ['title', 'team_country', 'team_logo']
def __init__(self, *args, **kwargs):
super(TeamForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
field.widget.attrs.update({'class': 'input'})
models.py
from django.db import models
# Create your models here.
from django.contrib.auth.models import User
from django_countries.fields import CountryField
from .validators import validate_file_size
class Team(models.Model):
#
# Status
ACTIVE = 'active'
DELETED = 'deleted'
CHOICES_STATUS = (
(ACTIVE, 'Active'),
(DELETED, 'Deleted')
)
#
# Fields
title = models.CharField(max_length=255)
team_country = CountryField(blank=True, null=True)
team_logo = models.ImageField(
null=True, blank=True, upload_to='logos/', default="logos/logo.png",
validators=[validate_file_size])
members = models.ManyToManyField(User, related_name='teams')
created_by = models.ForeignKey(User, related_name='created_teams', on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
status = models.CharField(max_length=10, choices=CHOICES_STATUS, default=ACTIVE)
class Meta:
ordering = ['title']
def __str__(self):
return self.title
views.py
from django.shortcuts import render
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from django.shortcuts import render, redirect, get_object_or_404
from .models import Team
@login_required
def add(request):
profile = request.user.profile
form = TeamForm()
if request.method == 'POST':
form = TeamForm(request.POST, request.FILES)
if form.is_valid():
team = form.save(commit=False)
team.created_by = request.user
team.members.add(request.user)
team.save()
profile.active_team_id = team.id
profile.save()
return redirect('account')
context = {'form': form}
return render(request, 'team/add.html', context)
When I try to do it without forms like for example with only title field:
@login_required
def add(request):
if request.method == 'POST':
title = request.POST.get('title')
if title:
team = Team.objects.create(title=title, created_by=request.user)
team.members.add(request.user)
team.save()
userprofile = request.user.profile
userprofile.active_team_id = team.id
userprofile.save()
return redirect('account')
return render(request, 'team/add.html')
It is successfully adds it. What am I doing wrong in here?
CodePudding user response:
You cannot add a member to group that does not yet exist, so you need to add the user after the group has been created for example :
if form.is_valid():
team = form.save(commit=False)
team.created_by = request.user
team.members.add(request.user)
team.save()
is now :
if form.is_valid():
team = form.save(commit=False)
team.created_by = request.user
team.save()
team.members.add(request.user) # you can only add member after the group has been created
Same in the second snippet :
team = Team.objects.create(title=title, created_by=request.user)
team.save()
team.members.add(request.user)
