How to get value of a nested serializer field from its parent serializer class?
Consider the followings two serializers: class SerializerA(BaseSerializer): field_1 = serializers.IntegerField() field_2 = SerializerB() class SerializerB(BaseSerializer): field_3 = serializers.IntegerField() The input JSON for SerializerB will not contain field_3 and it has to obtained from field_1 of SerializerA. I have tried this class SerializerB(BaseSerializer): field_3 = serializers.IntegerField() def __init__(self, instance=None, data=empty, **kwargs): if data is not empty and isinstance(data, dict): _data = data.copy() _data['field_3'] = self.parent.initial_data.get('field_1') super(SerializerB, self).__init__(instance, _data, **kwargs) super(SerializerB, self).__init__(instance, data, **kwargs) But it is not working as data is always empty and it never passes the if statement. -

How to apply lookups in django filter query according to conditions?
I want to make a query where i can apply lookups only when some conditions satisfy. e.g A customer can pick only that food from stall for which he paid for class Customer(models.Model): food_type = models.CharField() fruit_id = models.ForeignKey(Fruit, null=True) vegetable_id = models.ForeignKey(Vegetable, null=True) is_paid = models.BooleanField() class Food(models.Model): fruit_id = models.ForeignKey(Fruit, null=True) vegetable_id = models.ForeignKey(Vegetable, null=True) So i need to do something like: q = Food.objects.all() if Customer.objects.filter(id=(id of customer), food_type='fruit', is_paid=True).exists(): q = q.filter(fruit_id__in=Customer.objects.filter(id=(id of customer), food_type='fruit', is_paid=True).values_list('fruit_id', flat=True)) if Customer.objects.filter(id=(id of customer), food_type='vegetable', is_paid=True).exists(): q = q.filter(vegetable_id__in=Customer.objects.filter(id=(id of customer), food_type='vegetable', is_paid=True).values_list('vegetable_id', flat=True)) How can i optimize this as this is a small example, in my case there are many more conditions. I want to reduce the number of times it is hitting the database. Also is there any way i can use conditional expressions here? e.g When() Any help will be appreciated. -

Fail to enable Smartsheet webhook (502 Bad Gateway)
Django: 4.0.6 Smartsheet Python SDK: 2.105.1 Ngrok: 3.0.6 I have a Django server running on localhost, forwarded my localhost through Ngrok, have setup a callback route for accepting/responding to the Smartsheet-Hook-Challenge, and created a webhook instance using Python SDK. However, when I try to enable my webhook by running the following (documented here): Webhook = smartsheet_client.Webhooks.update_webhook(webhook_id,smartsheet_client.models.Webhook({'enabled': True})) Ngrok immediately returns 502 bad gateway, and my webhook instance's disabledDetails attribute becomes Request returned HTTP status code 502 (ref id: wtegm9). And I have no clue what's the cause of this 502. PS: While I'm writing this question, I was able to successfully enable my webhook using cURL command, so I can go ahead and start working. But enabling the same webhook instance with update_webhook python method still gives 502. Since updating webhook with cURL worked, could it be a bug in the Python SDK method itself? -

Django pull list of all users, but shows list of multiple users with only current users credentials
In Django, I am trying to get a list of all users. I use the following query: users = User.objects.all().order_by('id') I am able to get a list of all the users, but it outputs a list of all users, but only showing the current users credentials? If I have 20 users, it will show 20 users but only the information for the currently logged in user. For example, I want to see a table like: User | Email ------------ User1 | user1@test.com User2 | user2@test.com User3 | user3@test.com But if the current user that is logged in is User1, It shows: User | Email ------------ User1 | user1@test.com User1 | user1@test.com User1 | user1@test.com Or if User2 is logged in, it shows: User | Email ------------ User2 | user2@test.com User2 | user2@test.com User2 | user2@test.com Here is my view.py: def portal_users(request): users = User.objects.all().order_by('id') return render(request, 'portal/users.html', {"users": users}) templates {% for users in users %} <tr> <td>{{user.username}}</td> <td>{{user.email}}</td> </tr> {% endfor %} -
Django.db.models.field.CharField
I have a Django project that I'm trying to cobble together for a very basic survey that needs to be entered for demographic information. I've dummied up some data through the admin site in order to get my ListView working for the time being. Unfortunately I'm getting a strange response. I built the models.py to be a drop down of a full spelled out and then to keep it small, I've made the actual storage in the db 1-3 characters. When I get my list view, one that uses 1 character to store for gender presents as (<django.db.models.fields.CharField>,), I would like for it to present as as the larger name of "Male", "Female", "Non-binary". However for my race and ethnicity fields which are 2 & 3 characters, those are returning as the actual storage for the DB (i.e, 'AA', 'NHP'). I'm more comfortable with SQL, so I'm not opposes to adding a table for a key as there would only be 11 entries for now, but its possible that more things could be added down the line. models.py: from django.db import models from django.contrib import admin from django.contrib.auth.models import User # Create your models here. class StuData(models.Model): id_num = models.IntegerField(primary_key=True) … -

What is the best approach of using django and ajax?
I'm now working on my first big project and can't understand how to use Django with ajax. On my website there are several services which works separately and are written on javascript, but soemtimes I have to send some information to the server. Also I have custom admin interface which contains of different changing database operations. All these actions should be done without reloading the page (using ajax post and get requests). So, I think I have two ways of doing it: Using ajax and classic Django views for each operation. Using ajax and integrated into my website Django REST Framework API methods. The stumbling block is that I wouldn't use this API methods from any other types of clients, just call them from users' browsers via ajax. What is the best approach in my situation? It seems to me that the second way is more "serious", but I don't have much experience of making projects like this and can't speak directly. -

I am overriding the choices option defined in the model, which is just a blank tuple. Here's my models.py #For assigning Ciena loopbacks class Dia_Address(models.Model): order_reference = models.ForeignKey(Order, null=True, on_delete=models.CASCADE) equipment_hostname = models.CharField(max_length=500, null=True, verbose_name="Equipment Hostname", help_text="Hostname of the DIA device.") subnet = models.CharField(max_length=200, null=True, choices=DIA_SUBNETS, help_text="Subnet in which the DIA device requires an address.") Contents of my forms.py, which overrides the model choices. class Dia_AddressForm(ModelForm): class Meta: model = Dia_Address fields = ['equipment_hostname', 'subnet'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) #order_id = str(order_reference.id) dcn_address_handler = AddressHandler subnet_id = "94806" DIA_SUBNETS = () NEW_SUBNETS = dcn_address_handler.get_subnet_data(dcn_address_handler, subnet_id) DIA_SUBNETS = NEW_SUBNETS + DIA_SUBNETS self.fields['subnet'].choices = DIA_SUBNETS Contents of my views.py def addDia_Address(request, pk_test): order = Order.objects.get(id=pk_test) dia_address_form = Dia_AddressForm() if request.method == 'POST': dia_address_form = Dia_AddressForm(request.POST) dia_address_form.instance.order_reference = order if dia_address_form.is_valid(): dia_address_form.save() return redirect('order', pk_test) context = {'dia_address_form':dia_address_form} return render(request, 'orchestration/dia_address_form.html', context) The issue I have is this form is failing validation. I am able to select the appropriate option from the form dropdown menu. Is there any way I can disable this validation for just this one charfield?
