You have provided HttpReponse only for POST and valid form. You should give the standard response (with empty form) for fresh entries or posting with errors. Like this:

def update_department(request, department_code):
dep_up = Departments.objects.get(department_code=department_code)
if request.method == "POST":
form = DepartmentsForm(request.POST, instance = dep_up)
if form.is_valid():
...
return HttpResponseRedirect('department_list')
form = DepartmentsForm()
return render(request, 'template.html', context={'form': form})

How to set the current date to an input type = date form in Django

manufbank = models.TextField()
manufcode = models.CharField(max_length = 255, primary_key=True, editable=False)
def __str__(self):
return self.manufname
Right now, nothing happens when the form renders. What I want is the date in the Created Date should be set to today's date. However the user could leave it as is or could select a date of his/her choice. But the requirement is that date field should be pre-populated with the current date.
Please find below the screenshot of the web form.
Web Form

To save the current use auto_now=True
class DateField(auto_now=False, auto_now_add=False, **options)¶
A date, represented in Python by a datetime.date instance. Has a few extra, optional arguments:
DateField.auto_now¶
Automatically set the field to now every time the object is saved. Useful for “last-modified” timestamps. Note that the current date is always used; it’s not just a default value that you can override
To display current date in the form use :
form = CreateManufacturerForm(initial={'createddate': datetime.now()})

So, after a lot of frustrating hours, I was able to finally solve the problem, with help from my friend Houda. This is what I did.
views.py
In the GET portion of the code, I wrote the following.
initial_data = {
'createddate' : date.today().strftime("%Y-%m-%d"),
}
form = CreateManufacturerForm(initial = initial_data)
template.html file
I changed the following
<input type="date" id="createddate" name = "createddate" class="form-control" autofocus required="true" value = '{{ form.createddate.value }}'>
I am not sure if this is the best solution. But at least I got it to work. I believe the issue had something to do with the date format that HTML has for the
input type = 'date'
it only allows 'YYYY-mm-dd'
Thanks everyone.

When I put "SEND" button,I wanna show photo.html in the browser.But now the error happens, although I wrote registration/accounts/photo.html in render.I really cannot understand how to fix this.What should I do?

In render pass request as first argument.
return render(request, 'registration/accounts/photo.html', {'form':form})
It will work fine.
