Vue Js and Django get fields from ForeignKey Objects
I am using Django Rest Framework with Vue JS and currently unable to get the foreignkey fields from the actual model of the api. I want to be able to get the store name of a particular product. Whenever I try to call [[ product.store.name ]] in my vue template it returns nothing. Also my href does not return the slug of a store. This could be an easy fix, but I am hopeful to get a solution. Below is my code, thanks. models.py class Store(models.Model): owner = models.ForeignKey("account.Profile", null=True, on_delete=models.SET_NULL) category = models.ForeignKey("store.Category", null=True, on_delete=models.SET_NULL) name = models.CharField(max_length=30, unique=True) slug = AutoSlugField(populate_from='name', unique=True, editable=True) description = models.CharField(max_length=255, blank=True) def __str__(self): return str(self.id) class Product(models.Model): store = models.ForeignKey("store.Store", null=True, on_delete=models.SET_NULL, related_name='product_store') category = models.ForeignKey("store.Category", related_name='product_category', on_delete=models.CASCADE) sub_category = models.ForeignKey("store.SubCategory", related_name='product_sub_category', on_delete=models.SET_NULL, blank=True, null=True) created_by = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name='product_creator') title = models.CharField(max_length=255) description = models.TextField(blank=True) slug = AutoSlugField(populate_from='title', unique=True) price = models.DecimalField(max_digits=10, decimal_places=0) serializer.py class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = '__all__' views.py class ProductListAPIView(generics.ListAPIView): pagination_class = MyCustomPagination queryset = Product.objects.all().order_by('-date_created') # queryset = Product.objects.all() serializer_class = ProductSerializer products.js <script> new Vue({ el: "#blog", delimiters: ['[[', ']]'], data() { return { products: [], currentPage: 1, hasNext: true, loading: true, … -

Django - Is it possible to prefetching multiple filters for queryset?
I know you can prefetch a single filtered queryset E.g. Parent.objects.all() .prefetch_related( Prefetch("child_set", queryset=Child.objects.filter(type="A") ) That way running obj.child_set.all().count() will return the count of related A Childs without running another query. But what if I wanted to have the B count too? So the following would take 2 queries - can I somehow prefetch them both? return { "a_count": obj.log_set.filter(type="A").all().count(), "b_count": obj.log_set.filter(type="B").all().count(), } -

SES email being consistently hacked
I'm using Amazon SES email from the django-ses module. I have two SES-verified addresses; SES is restricted to sending only to those addresses. There's a DKIM string on my domain's DNS configuration. SES is accessed using django-ses from a contact form on my website that's protected by Recaptcha. Recently I've begun getting spam sent to those verified addresses coming from SES. Messages in Russian, messages containing website links, messages starting with "Hey guys...". I get about one per day. There are many questions on the net about SES emails going to the spam directory. That is NOT the issue here. The emails are received by my InBox; they are just bogus, hacked emails. I changed the SES API key and Secret key, to no avail. Where do I look next? (I don't have AWS Support, and find nothing in their Knowledge Base.) -
How to provide initial data to ForeignKey in ModelFormSet?
So I have this thing. These are the relationships of my models To define an event you have a Place, a QR Link and an ImageAlbum which have up to five Images.

The file is downloading in local but not in production server in Django Rest framework?
I have a simple API that downloads a file in the system. It works perfectly in the local server, but when I deploy the same code to production, it gives me a 500 server error.

Django complex query with a many to many field
Let's explain the problem. I am trying to filter out all Person that have certain attributes. These are my models: class Person(models.Model): community = models.ForeignKey( Community, on_delete=models.CASCADE, related_name="people" ) class Attribute(models.Model): community = models.ForeignKey( Community, on_delete=models.CASCADE, related_name="attributes" ) name = models.CharField(max_length=50) value = models.CharField(max_length=100) class Trait(models.Model): person = models.ForeignKey( Person, on_delete=models.CASCADE, related_name="person_attributes" ) attribute = models.ForeignKey( Attribute, on_delete=models.CASCADE, related_name="traits" ) A person could have the following attributes: Attribute(name='head', value='big') Attribute(name='head', value='small') Attribute(name='head', value='medium') Attribute(name='hands', value='white') Attribute(name='hands', value='red') #... These attributes are linked to Person through the Trait entity. Now, I have the following dict, witch I use to dynamically build the query: { "head": ["small", "medium"], "hands": ["white", "red"], } I want to filter out all the Person that have the attribute "head" with the value "small" or "medium" and the "hands" "white" or "red" This is what I have done so far, but it doesn't works: # value is the dict like the one explained above from which # I will obtain the elements for filtering def routine(self, value): query = Q() for attr, traits in value.items(): if len(traits) > 0: query &= Q( Q(person_attributes__attribute__name=attr) & Q(person_attributes__attribute__value__in=traits) ) return Person.objects.filter(query) -

How to send multiple email invitations with django-allauth and django-invitations
I installed django-invitations to use it together with django-allauth, but it doesn't let me send several mails at the same time, which is inefficient for the correct functioning of the app. Maybe I installed something wrong. I only wrote in setting.py this: ACCEPT_INVITE_AFTER_SIGNUP = os.getenv('ACCEPT_INVITE_AFTER_SIGNUP', True) #I think allow json invites is for multiple emails, but doesn't work INVITATIONS_ALLOW_JSON_INVITES = True INVITATIONS_LOGIN_REDIRECT = os.getenv('INVITATIONS_LOGIN_REDIRECT', '/') ACCOUNT_ADAPTER = 'invitations.models.InvitationsAdapter' Or maybe exists another app who send invitations with allauth, if anyone have any advices please comment, thanks. -

Advanced Search in Django with Multiple Fields and Keeping Filters in Pagination
I have this piece of code that is working already. It enables you to have a search form, to search in a specific table with multiple filters. The results are paginated, and this form allows you to keep these filters when you browse multiple pages. The problem I'm having now is that I am reusing this piece of code in another scenario, and it involved checking one filter in multiple fields in the database table. Example of a standard scenario: First Name Last Name City In this case, the view will be as such: def clean_filters(filters): filters = {k: v for k, v in filters.items() if v} return filters def search(request): filters = { "user__first_name__icontains": request.GET.get("fname_kw"), "user__last_name__icontains": request.GET.get("lname_kw"), "city__name__icontains": request.GET.get("city_kw"), } html_queries = { "fname_kw": request.GET.get("fname_kw"), "lname_kw": request.GET.get("lname_kw"), "city_kw": request.GET.get("city_kw"), } filters = clean_filters(filters) html_queries = clean_filters(html_queries) people = Person.objects.filter(**filters) page_num = request.GET.get("page", 1) p = Paginator(people.order_by("-pk"), 12) people = p.get_page(page_num) context = { "people": people, "cities": City.objects.all(), "filters": html_queries, } return render(request, "pages/index.html", context) And the HTML will be as such: <form method="GET" action="{% url 'search' %}"> <div class="row"> <div class="col-xl-3 col-lg-3 col-md-3 col-sm-12 col-xs-12"> <div class="row"> <div class="col-6"> <input class="form-control" name="fname_kw" id="search_fname" placeholder="First Name" /> </div> <div class="col-6"> … -

How can I set the width of excel columns before export? tables.py import django_tables2 as tables from .models import Customer class CustomerTable(tables.Table): export_formats = ['xls','xlsx','csv'] class Meta: model = Customer fields = ('orderorbarcode','item_barcode','order_id', 'full_name','company','email','phone_number','note') html part <div class="container"> {% for format in table.export_formats %} <a id="{{format}}" href="{% export_url format %}">.{{ format }}</a> {% endfor %} {% render_table table %} </div> -
Extend User model in Django with jwt authorization
I am trying to extend User model in Django. I already have authorization using jwt Token and I am currently trying to add another field to User model, such as phone number and address. My views.py looks like this: class MyObtainTokenPairView(TokenObtainPairView): permission_classes = (AllowAny,) serializer_class = MyTokenObtainPairSerializer class RegisterView(generics.CreateAPIView): queryset = User.objects.all() permission_classes = (AllowAny,) serializer_class = RegisterSerializer models.py like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) phone_number = models.IntegerField(blank=False) address = models.CharField(max_length=500, blank=True) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() In here I'm trying to create another class that will store phone number and address. How can I incorporate my Profile class into User so that it will create new user model and what is more use earlier implemented Token authorization. -
Multiple nested choices in Django models
Forgive me if I'm not describing this correctly - I'm still learning and I've hit a wall with a problem I'm working on. I want to create a way (in the Admin backend for now) for users to show the books they like by fiction/non-fiction, age-range, genre(s) and sub-genre(s). So, a user who liked gothic horror books could select fiction>adult>horror>gothic. Or, a user who likes literally all YA books could select fiction>Young Adult and their selection would cascade down to every genre and sub-genre. I think the Choices field option and the MultiSelectField functionality might be a start, but there doesn't seem to be a way to add 'layers' to the choices beyond the categories below, and it seems like an inelegant solution when there could be hundreds of choices. I also don't know how it could be presented in the Admin - ideally with checkboxes that can 'open up' to show the sub-categories beneath them. GENRE_CHOICES = ( ('Fiction', ( ('FCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ('Non-Fiction', ( ('NCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ) genres = MultiSelectField(max_length = 100, choices=GENRE_CHOICES, null=True) I don't even know the name of … -
