Cannot filter a query once slice has been taken django
Follow up onto: AutoField should be present but it's not (django)? related to: "Cannot update a query once a slice has been taken". Best practices? I don't need to filter objects, only order by date and select the most recent one: def get_latest_currency(self): """ Return most up to date value """ up_to_date_currency = Currency.objects.order_by('-currency_value_in_dollars_date')[:1] if not up_to_date_currency.exists(): # No objects yet; fetch currencies update_coins_table() return Currency.objects.order_by('-currency_value_in_dollars_date')[:1] up_to_date_currency is initialized correctly; the last line gives: assert not self.query.is_sliced, \ AssertionError: Cannot filter a query once a slice has been taken. This code represents a view (I want to return a plain JSON object (this is a REST endpoint)). Why is django complaining about a filter when only a slice was used? -

Django Serializer - How to know which parameters was input wrongly
I always put serializers in an try statement that returns false when have invalid format. Like this: Sample model: from rest_framework import serializers class CommentSerializer(serializers.Serializer): email = serializers.EmailField() content = serializers.CharField(max_length=200) created = serializers.DateTimeField() Sample code: try: testSerializer(data = b).is_valid() except: return HttpResponse("Invalid data type input) Now, I want to return parameters was input incorrectly like this: Parameters: Name, Email was input in wrong type -
AutoField should be present but it's not (django)?
Looking at: https://docs.djangoproject.com/en/3.1/ref/models/instances/#django.db.models.Model.save For convenience, each model has an AutoField named id by default unless you explicitly specify primary_key=True on a field in your model. See the documentation for AutoField for more details. and https://docs.djangoproject.com/en/3.1/topics/db/models/ it seems clear that an object always has an id. I have a model: class Currency(models.Model): currency_name = models.CharField(max_length=100) currency_value_in_dollars = models.FloatField() currency_value_in_dollars_date = models.DateField() def __str__(self): return self.currency_name that I've migrated as: operations = [ migrations.CreateModel( name='Currency', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('currency_name', models.CharField(max_length=100)), ('currency_value_in_dollars', models.FloatField()), ('currency_value_in_dollars_date', models.DateField()), ], ), and when trying to add entries to the db like: def update_coins_table(): if not do_greeting(): print("Gecko crypto board not reachable. Db setup") return crypto_coins_prices = cg.get_price(ids=coins_ids_str, vs_currencies='usd') timezone_now = timezone.now() for coin_key in crypto_coins_prices: coin = Currency(coin_key, crypto_coins_prices[coin_key]['usd'], timezone_now) coin.save() the line: coin = Currency(coin_key, crypto_coins_prices[coin_key]['usd'], timezone_now) gives: unable to get repr for <class 'manage_crypto_currency.models.Transaction'> and coin.save() fails. If I replace the line in question with: coin = Currency(1, coin_key, crypto_coins_prices[coin_key]['usd'], timezone_now) it works. Shouldn't the id auto increment? The last line always overwrites the previous and only one entry gets stored in the end. -
How to authorize my API requests with django google-auth?
I have implemented google-auth in my Django project, using allauth, and it works perfectly. After successful verification, I get some key from this view. from allauth.socialaccount.providers.google.views import GoogleOAuth2Adapter from rest_auth.registration.views import SocialLoginView class GoogleLogin(SocialLoginView): adapter_class = GoogleOAuth2Adapter { "key": "12b6e1696cdd73ddede1334f683003f63426f423" } At this point how can I authorize my other API requests by this key to identify a user on my server? Or what else I need to do ? How to use this key in my other requests ? -

Unable to Create with OneToOneField Django
I'm stuck with this issue for a while now and couldn't find a solution. Here is the issue: Background: I have CustomUser(AbstractUser) model and HeroesUser which has OneToOneField relationship with CustomUser model.

Is there a way to get the columns from a joined table in the model instance dict object?
t = PurchaseHeader.objects.first() t.__dict__ { '_state': <django.db.models.base.ModelState object at 0x7f4b34aa7fa0>, 'id': 3, 'ref': 'jhkh', 'goods': Decimal('-100.00'), 'discount': Decimal('0.00'), 'vat': Decimal('-20.00'), 'total': Decimal('-120.00'), 'paid': Decimal('-120.00'), 'due': Decimal('0.00'), 'date': datetime.date(2020, 11, 7), 'due_date': datetime.date(2020, 11, 14), 'period': '202007', 'status': 'c', 'created': datetime.datetime(2020, 11, 7, 15, 46, 48, 191772, tzinfo=<UTC>), 'cash_book_id': None, 'supplier_id': 1128, 'type': 'pc' } When I joined the supplier table I was disappointed to find that the columns are not included in the dict. Below, t.__dict__ is the same as above. I noticed that the Supplier model instance is cached inside of t._state so I guess I could create my own method which all models inherit from which does what i want - all the columns from all tables inside a dict. But I wondered if anybody knew a way of doing this sort of thing out of the box? t = PurchaseHeader.objects.select_related("supplier").first() t.__dict__ -
Ckeditor texteditor not appearing in django admin where RichTextfield is applied

Django enum named groups
I want a listing to be able to have a specific category, so the seller will choose a general category and then onto a more specific one, for example: Men's Wear: Jeans: Skinny Fit Slim Fit Regular Fit Pants: Slim Fit Formal Casual Women's Apparel: Tops: Tunics Denim: Jeans I tried the named groups like in django docs: https://docs.djangoproject.com/en/3.0/ref/models/fields/#field-choices-named-groups MEDIA_CHOICES = [ ('Audio', ( ('vinyl', 'Vinyl'), ('cd', 'CD'), ) ), ('Video', ( ('vhs', 'VHS Tape'), ('dvd', 'DVD'), ) ), ('unknown', 'Unknown'), ] But when I tried, it gives the error product.Listing.category: (fields.E005) 'choices' must be an iterable containing (actual value, human readable name) tuples. here is my code: class Listing(models.Model): CATEGORY = [ ('Women\'s Apparel', ( ('Dresses', ( ('party_dresses', 'Party Dresses'), ) ), ), ), ] id = models.AutoField(primary_key=True) title = models.CharField(max_length=255) description = models.CharField(max_length=255) new_condition = models.BooleanField() category = models.CharField(choices=CATEGORY, max_length=255) why is it showing error ? is it because the enum groups cant be nested more than 1 level ? thank you -
Is there a way to send a form class as parameter to a function in a template in django?
I'm creating a website that has multiple pages that each has one form. This one form on each page has an "add", "modify" and "delete" button. I need to create a lot functions to process all this because they are on different pages working with different form classes and model classes. To create a more general approach it would be usefull if I could just pass the form class and/or model class as a parameter in a template to a view (se example below). When writing a capture pattern for this in the urls.py file I cant find anything to capture a reference to an object though like a form class or model class... I only see that you can capture strings, integers and so on. What im thinking about is something like this: {% url '' id form_class %} where id and form class are the parameters to the view. Is there any way to actually do this ? I want to do this so I dont have to write add, modify and delete view functions for every form on every page and instead have one add, modify and delete for every form without having if loops and checking … -
Delete an object with a large number of CASCADE models on Django
I am running into an issue where I cannot delete user accounts with Django. The problem is that there are several other models in code that have the field: user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True) These models themselves have other models that are set to be deleted with on_delete=models.CASCADE when they are deleted. So when I try to delete a user that had a lot of activity on my website, it can quickly become tens of thousands of items to delete. This causes the delete operation to never end and the account to not get deleted. Worse, only some of the content gets deleted as the operation is interrupted. How should I handle deleting a model with many CASCADE delete linked to it? I am using Django 3.1 with a MySQL db. -
Django: posting information to multiple models with one html form
I'm building my first solo django project right now so I'm learning a lot. I've run into a problem that I can't think how to fix.

This is my forms.py class Quarterbackform(forms.ModelForm): class Meta: model = Quarterback fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'id':'QB_name'}) } class Runningbackform(forms.ModelForm): class Meta: model = Runningback fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'id':'RB_name'}) } class Widereceiverform(forms.ModelForm): class Meta: model = Widereceiver fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'id':'WR_name'}) } class Tightendform(forms.ModelForm): class Meta: model = Tightend fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'id':'TE_name'}) } class Kickerform(forms.ModelForm): class Meta: model = Kicker fields = "__all__" widgets = { 'name': forms.TextInput(attrs={'id':'K_name'}) } My views.py has this function to save player selections to their respective model. def emp(request): url = 'hidden' r = requests.get(url.format()).json() player_data = [] #print(r) … -

Registration user with multiple usernames - Django REST

The question is what is right way to implement the registration serializer? Should I get all the fields in User and UserNicknames and then do the logic or there is …
