How to add username of currently logged in user to field in my model? For example, I need to store info about user like name, email and so on in model, other than default Django user model, but I still use default one to store credentials. I want to establish relationship between those, so I created username field in my model. How do I fill it with current user's username upon saving the corresponding form? My model
class ApplicantProfile(models.Model):
name = models.CharField(max_length = 50)
dob = models.DateField()
email = models.EmailField()
description = models.TextField()
username = <something>
What do I change <something> with?
My form
class ApplicantProfileEdit(forms.ModelForm):
class Meta:
model = ApplicantProfile
fields = [
'name',
'dob',
'email',
'description',
]
My view
def ApplEditView(request):
form = ApplicantProfileEdit(request.POST or None)
if form.is_valid():
form.save()
form = ApplicantProfileEdit()
context = {
'form':form
}
return render(request, "applProfileEdit.html", context)
P.S. I tried to import models straight to my views.py, and assign request.user.username to username field of the model in my view, but it didn't work, just left that field empty. I had username as CharField when I tried this.
It is not a good idea to save the username itself, or at least not without a FOREIGN KEY constraint. If later a user changes their name, then the username now points to a non-existing user, if later another user for example changes their username to thatusername, then your ApplicantProfile will point to the wrong user.
Normally one uses a ForeignKey field [Django-doc], or in case each ApplicantProfile points to a different user, a OneToOneField [Django-doc]:
from django.conf import settings
from django.db import models
class ApplicantProfile(models.Model):
name = models.CharField(max_length = 50)
dob = models.DateField()
email = models.EmailField()
description = models.TextField()
# maybe a OneToOneField
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)In the view:
from django.contrib.auth.decorators import login_required
from django.shortcuts import redirect
@login_required
def appl_edit_view(request):
if request.method == 'POST':
form = ApplicantProfileEdit(request.POST)
if form.is_valid():
form.instance.user = request.user
form.save()
return redirect('some-view-name')
else:
form = ApplicantProfileEdit()
context = {
'form':form
}
return render(request, 'applProfileEdit.html', context)Note: In case of a successful POST request, you should make a
redirect[Django-doc] to implement the Post/Redirect/Get pattern [wiki]. This avoids that you make the same POST request when the user refreshes the browser.
Note: You can limit views to a view to authenticated users with the
@login_requireddecorator [Django-doc].
