Django form : Setting the user to logged in user - django

Question

I am trying to create an address book website where logged in user is able to fill in a form and store contact information. I was able to implement the login and logout functionality. But the problem is that I am not able to set the username to current logged in user. Here is what I have implemented so far:
Models.py
class UserProfileInfo(models.Model):
user = models.OneToOneField(User,on_delete=models.CASCADE,primary_key=True)
#additional
def __str__(self):
return self.user.usernname
class UserContacts(models.Model):
current_user = models.ForeignKey(User,on_delete=models.CASCADE)
first_name = models.CharField(max_length = 150)
last_name = models.CharField(max_length = 150)
phone_number = models.CharField(max_length = 150)
email_address = models.CharField(max_length = 150)
street_address = models.CharField(max_length = 350)
def __str__(self):
return '{}'.format(self.first_name)
Forms.py
class UserForm(forms.ModelForm):
password = forms.CharField(widget = forms.PasswordInput())
class Meta():
model = User
fields = ('username','email','password')
class UserContactForm(forms.ModelForm):
class Meta():
model = UserContacts
fields = "__all__"
views.py:
#login_required
def new_contact(request):
form = UserContactForm()
current_user = request.user.get_username()
user = User.objects.filter(username=current_user).first()
output = UserContacts.objects.filter(current_user_id=user.id).first()
if request.method == "POST":
form = UserContactForm(request.POST)
if form.is_valid():
form.save(commit=True)
return index(request)
else:
print('Error Form Invalid')
return render(request,'basic_app/contact.html',{'form':form})
Here is how the output looks like when the logged in user tries to enter contact information details:
Updating contact screenshot. As you can see the current user has to select his username to fill out the contact information.
How to overcome this and by default set the username in the form to the current logged in user

Answer 1

Change your UserContactForm to include an extra perameter in __init__, and set the initial value on the user field:
class UserContactForm(forms.ModelForm):
class Meta():
model = UserContacts
fields = "__all__"
def __init__(self, *args, **kws):
# To get request.user. Do not use kwargs.pop('user', None) due to potential security hole
self.user = kws.pop('user')
super().__init__(*args, **kws)
self.fields['user'].initial = self.user
Then change you view to add in the request.user to the form construction:
#login_required
def new_contact(request):
form = UserContactForm(user=request.user)
current_user = request.user.get_username()
user = User.objects.filter(username=current_user).first()
output = UserContacts.objects.filter(current_user_id=user.id).first()
if request.method == "POST":
form = UserContactForm(request.POST, user=request.user)
if form.is_valid():
form.save(commit=True)
return index(request)
else:
print('Error Form Invalid')
return render(request,'basic_app/contact.html',{'form':form})
You could probably remove the:
current_user = request.user.get_username()
user = User.objects.filter(username=current_user).first()
output = UserContacts.objects.filter(current_user_id=user.id).first()
