here's my code
i can't update my data if i used type "file"
My form can't be updated, I try print(form.error) but "this field requirement" appears, even though the form is filled out
views.py :
#login_required
def data_karyawan_edit(request, id):
karyawan = Karyawan.objects.get(id=id)
ar_divisi = Divisi.objects.all()
if request.method == 'POST':
form = KaryawanForm(request.POST, request.FILES, instance=karyawan)
print(form.errors)
if form.is_valid():
form.save()
messages.success(request, "Berhasil disimpan")
return redirect('data_karyawan')
else:
form = KaryawanForm()
return render(request, "data_karyawan/edit.html", {'karyawan': karyawan, 'ar_divisi': ar_divisi})

I'am trying to do a website and I have problem with uploading the file. On admin site I can upload and import any file but when I create view, I get this:
"The view main.views.licz didn't return an HttpResponse object. It returned None instead."
Here is the code from main.models:
class Plik(models.Model):
file = models.FileField(upload_to='uploads/')
Code from forms.py:
class upload(forms.Form):
title = forms.CharField(max_length=50)
file = forms.FileField()
And code from views.py:
def licz(request):
if request.method == "POST":
form = upload(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect("main/licz.html", {"form":form})
else:
form = Plik()
return render(request, "main/licz.html", {"form":form})
Plz I am trying to solve this like 5 days...
def licz(request):
if request.method == "POST":
form = upload(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect("main/licz.html", {"form":form})
else:
form = Plik()
return render(request, "main/licz.html", {"form":form})
# if request is GET, python will execute this part of the function
Your livz function does not return anything on a GET request.
If no return statement is given, Python will return None.
The return render(...) is only executed on a POST request (when the form is submitted) with invalid form.
You need to also render your page on other request method.
A typical form view should look like the following (pay attention to the indent):
def form_view(request):
if request.method == 'POST':
form = MyForm(data=request.POST)
if form.is_valid():
# do stuff with the form
return HttpResponseRedirect('/success-url')
else:
form = MyForm()
return render('my-template', {'form': form})
Pay attention to your conditions (if/else/...) and make sure your page return a response in every possible path the code execution takes.
def licz(request):
if request.method == "POST":
form = upload(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect("main/licz.html")
else:
form = Plik()
return render(request, "main/licz.html", {"form":form})
I'm trying to save the default data of my form and model with a simple function in Django but when I use the condition of is_valid() never enter to the condition. What can I do ?
This is for views.py
def entreno1B(request):
if request.method == 'POST':
form=Entreno(request.POST)
if form.is_valid():
print("is valid")
form.save()
return render(request, 'training/entrenosB1.html')
my model is
class Entrenos(models.Model):
tiempo1D1 = models.FloatField(max_length=1000,default=0.0)
tiempo2D1 = models.FloatField(max_lenght=1000,default=0.0)
and my form is
class Entreno(forms.ModelForm):
class Meta:
model = Entrenos
fields = ('tiempo1D1','tiempo2D1',)
Please Help. I don't know what is my error. Thank you
Also, when I modify my views like this:
def entreno1B(request):
if request.method == 'POST':
form=Entreno(request.POST)
form.save()
if form.is_valid():
print("is valid")
form.save()
return render(request, 'training/entrenosB1.html')
I got the error that my object has no attibute 'cleaned_data'
I modify my function in views.py, and works. I do this:
def entreno1B(request):
if request.method == 'POST':
form=Entreno({'tiempo1D1':DATA, 'tiempo2D1':Data2})
if form.is_valid():
print("is valid")
form.save()
return render(request, 'training/entrenosB1.html')
So i have a model that i'm trying to save using a form which submits successfully, but in the Admin the object value None. I know the problem is in the views but i can't figure it out. Here's my code:
Views.py
def profilecreate(request):
if request.method == 'GET':
form = ProfileForm()
else:
form = ProfileForm(request.POST)
if form.is_valid():
description = form.cleaned_data['description']
caption= form.cleaned_data['caption']
photo = form.cleaned_data['photo']
profile = Profile.objects.create(description=description, caption=caption, photo=photo)
return HttpResponseRedirect(reverse('profile-id', kwargs={'profile_id': profile.id}))
return render(request, 'profile_form.html', {'form': form})
Someone please assist
Second view attempt
def profilecreate(request):
# if this is a POST request we need to process the form data
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = ProfileForm(request.POST)
# check whether it's valid:
if form.is_valid():
photo = form.cleaned_data['photo']
description = form.cleaned_data['description']
caption = form.cleaned_data['caption']
form.save(commit=True)
return HttpResponseRedirect('/')
# if a GET (or any other method) we'll create a blank form
else:
form = ProfileForm()
return render(request, 'profile_form.html', {'form': form})
currently, user can create only one post. but as a superuser I want to create more than one. I tried to do it in admin page but it won't work. Is there a way to do this?
#login_required
def add_category(request):
if Category.objects.filter(author=request.user).exists():
return render(request,'main/category_already_exists.html')
if request.method == 'POST':
category = Category(author=request.user)
form = CategoryForm(request.POST, instance=category)
if form.is_valid():
form.save(commit=True)
return redirect('index')
else:
form = CategoryForm()
return render(request, 'main/add_category.html', {'form':form})
#login_required
def add_category(request):
if not request.user.is_superuser and Category.objects.filter(author=request.user).exists():
return render(request,'main/category_already_exists.html')
if request.method == 'POST':
category = Category(author=request.user)
form = CategoryForm(request.POST, instance=category)
if form.is_valid():
form.save(commit=True)
return redirect('index')
else:
form = CategoryForm()
return render(request, 'main/add_category.html', {'form':form})
I'm attempting to modify a field after the user has submitted the form. I've found several pieces of code online, but none seem to work. Below is my attempt in views.py. Any guidance would be greatly appreciated.
def newlisting(request):
if request.method == "POST":
form = ListingsForm(request.POST)
if form.is_valid():
form.cleaned_data['condition'] = 1 #form.condition = 1 also fails
form.save()
return redirect('/listings/')
else:
form = ListingsForm()
return render(request, 'newlisting/newlisting.html', {'form':form})
you can do like:
def newlisting(request):
if request.method == "POST":
form = ListingsForm(request.POST)
if form.is_valid():
obj = form.save(commit=False)
obj.condition = 1
obj.save()
return redirect('/listings/')
else:
form = ListingsForm()
return render(request, 'newlisting/newlisting.html', {'form':form})
