I am trying to set initial values for my django model form
but when I try in my views.py:
add_contact_form = newContactForm(request.POST, initial={'relation':'Customer'})
It doesn't work. If I specify default values in the model they work fine.
Models.py:
class contact(models.Model):
name = models.CharField(max_length=20, blank=True)
email = models.EmailField(primary_key=True)
tel = PhoneField(null=True, blank=True)
contact_relations = [
('Supplier', 'Supplier'),
('Customer', 'Customer'),
('Other', 'Other'),
]
relation = models.CharField(max_length=50, choices=contact_relations)
Forms.py:
class newContactForm(forms.ModelForm):
class Meta:
model = contact
fields = [
'name',
'email',
'tel',
'relation',
]
widgets = {
'relation': forms.RadioSelect(),
}
Views.py:
def add_contact_view(request):
add_contact_form = newContactForm(request.POST, initial={'relation':'Customer'})
if add_contact_form.is_valid():
add_contact_form.save()
else:
add_contact_form = newContactForm()
context = {
"add_contact_form":add_contact_form,
}
return render(request, 'contacts/new_contact.html', context)
thats because you are not setting them when the page loads, you are initializing when the form is submitted.
def add_contact_view(request):
add_contact_form = newContactForm(request.POST)
if add_contact_form.is_valid():
add_contact_form.save()
else:
add_contact_form = newContactForm(initial={'relation':'Customer'})
context = {
"add_contact_form":add_contact_form,
}
return render(request, 'contacts/new_contact.html', context)

I am trying to save information from the form created out of the Django model. I am really not much experienced as this is my second project.
Here is my view
def profile_create_view(request):
form = ProfileCreateForm(request.POST or None)
if form.is_valid():
form.save
form = ProfileCreateForm()
context = {
'form':form
}
return render(request, 'users/profile', context)
my form is here
class ProfileCreateForm(forms.ModelForm):
class Meta:
model = Profile
fields = [
'avatar',
'user_type',
'first_name',
'last_name',
'gender',
'email',
'phonenumber',
'birth_date',]
and then my model is here
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
avatar = models.ImageField(upload_to = '', default = path_and_rename, blank=True)
provider = 'provider'
requester = 'requester'
user_types = [
(provider, 'provider'),
(requester, 'requester'),
]
user_type = models.CharField(max_length=155, choices=user_types, default=requester)
first_name = models.CharField(max_length=255, default='')
last_name = models.CharField(max_length=255, default='')
GENDER_MALE = 'Male'
GENDER_FEMALE = 'Female'
OTHER = 'Other'
GENDER_CHOICES = [
(GENDER_MALE, 'Male'),
(GENDER_FEMALE, 'Female'),
(OTHER, 'Other'),
]
gender = models.CharField(max_length=15, choices=GENDER_CHOICES, blank=True)
email = models.EmailField(default='none#email.com')
phonenumber = models.CharField(max_length=15, default='')
birth_date = models.DateField(default='1975-12-12')
Strange things happen in the view function, you have to rebuild it like this.
def profile_create_view(request):
if request.method == "POST":
form = ProfileCreateForm(request.POST, instance=request.user)
if form.is_valid():
form.save()
return redirect('/')
else:
form = form(instance=request.user)
return render(request, 'manage_authors.html', {'form': form})
sorry, I had forgotten I solved it by changing the model on avatar from
'avatar = models.ImageField(upload_to = '', default = path_and_rename, blank=True)'
to
avatar = models.ImageField(upload_to = 'uploads/', default='uploads/default.jpg')
I have an array of choice fields. I want the human-readable text as a response instead of just numbers.
How to deserialize an array choice field in Django Rest Frameworks?
Response
"categories": [
1,
2
],
Expected Response
"categories": [
"Carpentry",
"Interior"
],
class ChoiceArrayField(ArrayField):
def formfield(self,**kwargs):
defaults = {
'form_class': forms.TypedMultipleChoiceField,
'choices': self.base_field.choices,
}
defaults.update(kwargs)
return super(ArrayField, self).formfield(**defaults)
Model.py
categories_choices = (
(1,"Carpentry"),
(2,"Interior"),
(3,"Furniture"),
(4,"Plumber"),
(5,"Electrican"),
(6,"Construction"),
(7,"Painting"),
(8,"Flooring"),
(9,"Yard Settings")
)
categories = ChoiceArrayField(
base_field = models.CharField(max_length=32,choices=categories_choices, null=True,blank=True),
default=list,
null=True, blank=True
)
Serializer.py
class ProfileSerializer(serializers.ModelSerializer):
phone_number = serializers.IntegerField(source='phone.phonenum')
id = serializers.IntegerField(source='phone.id')
class Meta:
exclude = ('phone',)
model = ProfileModel
You can do like
class ProfileSerializer(serializers.ModelSerializer):
phone_number = serializers.IntegerField(source='phone.phonenum')
id = serializers.IntegerField(source='phone.id')
class Meta:
exclude = ('phone',)
model = ProfileModel
def to_representation(self, instance):
response = super().to_representation(instance)
categories = instance.get_categories_display()
response["categories"] = categories
return response
I've a model:
class ListingPrice(Timestamps):
price = models.ForeignKey("Price", on_delete=models.CASCADE)
location = models.ForeignKey("location", on_delete=models.CASCADE)
class Meta:
unique_together = ["price", "location"]
class Price(Timestamps):
package = models.ForeignKey("products.Package", on_delete=models.CASCADE)
locations = models.ManyToManyField("location", through="ListingPrice")
price = models.DecimalField(max_digits=11, decimal_places=3)
with a serializer:
class LocationSerializer(serializers.ModelSerializer):
name = LocalizedField()
class Meta:
model = location
fields = ['id', 'name']
class PriceSerializer(serializers.ModelSerializer):
locations = LocationSerializer(many=True, read_only=True)
class Meta:
model = Price
fields = ['package', 'locations', 'price']
def create(self, validated_data):
print("validated_data, validated_data)
and viewset:
class PriceViewSet(ModelViewSet):
queryset = Price.objects.all()
serializer_class = PriceSerializer
ordering = ['id']
permissions = {
"GET": ["view_minimum_listing_price", ],
"POST": ["add_minimum_listing_price", ],
'PUT': ['update_minimum_listing_price', ],
'DELETE': ['delete_minimum_listing_price', ],
}
In testing I'mm using the following:
data = {
"price": 15,
}
response = self.client.put(path=self.url, data=data, format='json', args=[1])
I'm trying to update the price in the instance with id 1, but neither put or update is not allowed? How to overcome this and update it?
edit: urls.py
router = SimpleRouter()
router.register('listing_price', PriceViewSet, basename='listing_price')

I know about that it must be a instance not a value when deal with the foreignKey.
but the error occured on binding time.
is this concerend with foreignKey??

after advice
no mart name is here.

this is debug variable when make Item Form
this is debug variable about queryset
this is debug variable about 1st member of queryset
ofcourse I did makemigrations, migrate.
I don't know why are you trying to approach like this. ModelForm has very nice way to handle FK, and if you want to show name of the MartModel object, then you can use ModelChoiceField's to_field_name option. For example:
class ItemForm(forms.ModelForm):
mart_id = forms.ModelChoiceField(queryset=MartModel.objects.all(), to_field_name='name')
class Meta:
model = ItemModel
fields = ['mart_id', 'name', 'price', 'expirationDate', 'stockYn']
Also, please change the name of the field mart_id to mart, because underneath django creates a field name mart_id, if you assign the field name to mart.
Finally, in the view, you should not call cleaned_data[...] before calling form.is_valid(). Unless the form is validated, the data won't be available in cleaned_data.
Update
(from comments) Add a __str__ method at the bottom of MartModel class:
class MartModel(models.Model):
...
def __str__(self):
return self.name
Here are my models and admin classes:

I am trying to implement django-select2, but when I use inlines in
PurchaseOrderAdmin it doesn't show the field where I have implemented
django-select2:
But when I remove inlines, it works fine:
Edit
Here is the ItemSelectForm
class ItemSelectForm(forms.ModelForm):
class Media:

filter(parent__parent__isnull=True).filter(parent__isnull=False))
sub_category_id = Category.objects.values_list('id',flat=True)
sub_category_name = Category.objects.values_list('name',flat=True)
sub_category_choices = [('', '--------')] + [(id, name) for id, name in
itertools.izip(sub_category_id, sub_category_name)]
sub_category = forms.ChoiceField(sub_category_choices)
except:
pass
item = forms.ModelChoiceField(queryset = Product.objects.all())
def __init__(self, *args, **kwargs):

self.fields['parent_category'].widget.attrs={'class': 'parent_category'}
self.fields['sub_category'].widget.attrs={'class': 'sub_category'}
self.fields['item'].widget.attrs={'class': 'item'}
It worked for me by adding the following line in the static/suit/js/suit.js
Add:
(function ($) {
Suit.after_inline.register('init_select2', function(inline_prefix, row){
$(row).find('select').select2();
});
