This is view.py of edit method
def edit(request, emp_id):
if request.method == 'POST':
emp = employee.objects.get(pk=emp_id)
form = EmployeForm(request.POST or None, instance=emp)
if form.is_valid():
form.save()
messages.success(request, ('Item has been edited'))
return HttpResponseRedirect('view_profile')
else:
emp = employee.objects.get(pk=emp_id)
return render(request, 'edit.html', {'emp': emp})
def view_profile(request):
employees = employee.objects.all()
args= {'user':request.user,'employees':employees}
return render(request,'profile.html',args)
This is my model page
class employee(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
email = models.EmailField(max_length=50)
gender = models.CharField(max_length=1,choices=(('M','Male'),
('F','Female')),blank=True)
age = models.PositiveIntegerField(blank=True, null=True)
salary = models.CharField(blank = True,max_length=50
def __str__(self):
return self.user.username
Please, any advice on how to troubleshoot or any documentation I can read.

You're not using the form properly. Forms are not only for validation, they are also responsible for rendering the error messages. You want to change your view to pass the form to the template:
def edit(request, emp_id):
emp = employee.objects.get(pk=emp_id)
if request.method == 'POST':
form = EmployeForm(request.POST, instance=emp)
if form.is_valid():
form.save()
messages.success(request, ('Item has been edited'))
# this one is probably not going to work
# as expected - you may want to check the
# doc for the `redirect` shortcut instead
return HttpResponseRedirect('view_profile')
else:
form = EmployeForm(instance=emp)
return render(request, 'edit.html', {'emp': emp, 'form':form})
Then in your template instead of manually writing the whole form markup, use the form for rendering so you have the validation errors correctly displayed.
