I'm trying to create reservation create view that allows to break down the reservation process into 3 stages for handling all the database queries and displaying relevant choices accordingly to linkage between models (Personnel Profile has many to many key on Service)
1st stage - allows user to select service
2nd stage - displays available staff members (PersonnelProfile) who are handling this service
3rd stage - displays all the free dates / times based on staff member schedule / existing reservations, POST creates the reservation
I got stuck at the 2nd stage as my form doesn't validate. I would appreciate any advise how to overcome this issue or how to handle the idea differently. Sorry for the long post :)
UPDATE
My goal is following:
1. User selects a service
2. Backend checks which personnel profiles are offering this service and returns from to select relevant user
3. Based on selected user backend checks availability (Schedule) of user, his existing reservations and returns form for date / hour selection
4. Reservation is created after user submits from with selected hour and time
I tried to do it with additional forms to split the process in stages, as I have no idea (unfortunately I'm still a newbie) how to handle such behaviour with one form and if it's possible or not. I would appreciate any tips / guidance on how to handle this.

Form is correctly rendered, but when the form is sent, no new entry is created. I can't get why. For me everything should be working.
I tried replicating your project twice, both times I had no issue copying your code directly. It works fine for me. I set up a couple of print statements in the view:
from django.shortcuts import render
from .forms import NewClientForm
from .models import Client
# Create your views here.
def new_client_view(request):
new_client_form = NewClientForm()
print('request method: ', request.method)
if request.method == "POST":
new_client_form = NewClientForm(request.POST)
if new_client_form.is_valid():
Client.objects.create(**new_client_form.cleaned_data)
print('new client created')
else:
print(new_client_form.errors)
context = {
"form": new_client_form
}
return render (request, 'clients/new-client.html', context)
This is what I see on the new client form page:
This is what I see on the command line as I visit the page and submit the form:
As you can see, once I visit the page, the view receives a GET request, which makes sense, and which I see from your comment that you're seeing too. Once I hit "Submit" the view receives a POST request, which then creates a new Client object.
I used the Django shell to confirm that the Client object was indeed created:
So your code is fine, it may have something to do with the way you're filling up your form, or maybe a browser issue, I can't really tell.
im new to Django. Im creating a bidding site, where users should be able to visit a page to create a new listing (item that they are going to put up).The form that they are required to submit has a few common fields and when valid, the said form should be saved.
Problem is, my listingcreateview() is not doing that. I submit a correct form but it wont save, it just redirects to the same form page and No errors are shown.
This because the submitted form is validated as invalid every time. I know this because of the two functions i added inside listingcreateview(), the second one is called.
It was working properly before, dont know what changes messed it up. If i add in the admin interface information by hand, it is saved successfully.
views.py:
class ListingCreateView(CreateView):
model = Listing
fields = ['title', 'content', 'image', 'min_bid', 'categories']
def form_valid(self, form):
form.instance.seller = self.request.user
return super().form_valid(form)
def form_invalid(self, form):
return HttpResponseRedirect(reverse("index"))

categories = models.CharField(max_length=25, choices = category)
seller = models.ForeignKey(User, on_delete=models.CASCADE) ##

image_thumbnail = ImageSpecField(source='image', processors=[ResizeToFill(300, 150)], format='JPEG', options={'quality':100})

Good morning guys, I have a problem with a form.

Everything seems ok but not save, if I try with {{form.as_table}} it save.
I think there is a problem with custom field but I don't know how.
whats wrong?
TY
I subscribed the code of my model, and after this i'm rendering this form django to put on a bootstrap form. I'm trying, without no sucess, put a datepicker in this form, but I dont found it in anywhere how to do this.
This is my model:
class Usuario(User):
user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
birthday = models.DateField("Birthday")
class Meta:
verbose_name = "Usuario"
This other code is about the form:
class FormUsuario(UserCreationForm):
class Meta:
model = Usuario
fields = ("username", "email", "birthday")
def __init__(self, *args, **kwargs):
super(FormUsuario, self).__init__(*args, **kwargs)
self.fields['username'].widget.attrs['placeholder'] = "Usuário"
self.fields['email'].widget.attrs['placeholder'] = "Email"
self.fields['password1'].widget.attrs['placeholder'] = "Senha"
self.fields['password2'].widget.attrs['placeholder'] = "Confirmar senha"
self.fields["birthday"].help_text = "mm/dd/aaaa"
self.fields['email'].required = True
When I used {% csrf_token %} {{ form|bootstrap_horizontal }} on template, is not show a datepicker.
{% load bootstrap %}
<form class="form-horizontal" method="POST" action="/cadastro/">
{% csrf_token %}
{{ form|bootstrap_horizontal }}
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-success btn-lg btn-block">Salvar</button>
</div>
</div>
</form>
{% endblock %}
How can I make up a datepicker on my bootstrap form?
