Django actual value in choice field form - django

Question

I have models like this:
class Projects(models.Model):
project = models.CharField(max_length=150, blank=True, null=True)
def __str__(self):
return self.project
class Profile(models.Model):
user = models.OneToOneField(get_user_model(), on_delete=models.CASCADE)
project = models.ForeignKey(Projects, on_delete=models.CASCADE, null=True, blank=True)
def __str__(self):
return self.user.username
I also made a form in which I want to change current Project assigned Profile:
class ProjectForm(ModelForm):
class Meta:
model = Profile
fields = [
'project'
]
My view looks like this:
def change_project(request, user):
user = User.objects.filter(username=user)[:1].get()
profile = Profile.objects.get(user=user)
form = ProjectForm(request.POST, instance=profile)
if request.method == 'POST':
if form.is_valid():
form.save()
context = {'form': form}
return render(request, 'datafiller/change_project.html', context)
I can change the project using this form, but every time I want to do it again the form looks like this
How can I show in the form the current project instead of "------"?

You should not ground the ProjectForm in case you render the form with a GET requuest:
from django.shortcuts import get_object_or_404
def change_project(request, user):
profile = get_object_or_404(Profile, user__username=user)
if request.method == 'POST':
form = ProjectForm(request.POST, instance=profile)
if form.is_valid():
form.save()
else:
form = ProjectForm(instance=profile)
return render(request, 'datafiller/change_project.html', {'form': form})
