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. An event may or may not have a Place An event MUST have the main image which is marked by the main attr in the Image Form. All the forms are in the same page, they all are processed with a single Submit Now my troubles begin and end in the Forms Department, i have several Model Forms: #FORMS FILE class EventForm(ModelForm): date_time_start = forms.DateTimeField(input_formats=["%Y-%m-%d"], required=True, widget=forms.DateTimeInput(format="%Y-%m-%d", attrs={"id": "cal_start", "placeholder": "yyyy-mm-dd"})) has_place = forms.BooleanField() class Meta: model = Event fields = ['title', 'subtitle', 'phrase', 'date_time_start', 'prices', 'has_place'] class BaseImageFormSet(BaseModelFormSet): def clean_main(self): """Checks that there is only one main image""" if any(self.errors): return boolean_arr = [] for form in self.forms: if self.can_delete and self._should_delete_form(form): continue main_data = form.cleaned_data.get('main') main = main_data if main_data is not None else False if sum(boolean_arr) > 1: raise ValidationError('There can only be one main image.') boolean_arr.append(main) class PlaceForm(ModelForm): class Meta: model = EventPlace exclude = ['uuid', 'event'] class QRForm(ModelForm): class Meta: model = EventQR exclude = ['uuid', 'event'] My headache is with the 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. If I try with another id that doesn't exist, it will say the object is not found. My code is as follows. def get_permissions(self): """ Instantiates and returns the list of permissions that this view requires. """ if self.request.query_params.get("download") == "file": return [] return [permission() for permission in self.permission_classes] def get(self, request, *args, **kwargs): if request.query_params.get("download") == "file": return self.download_file(request) /....other codes........./ def download_file(self, request, *args, **kwargs): instance = self.get_object() file_handle = instance.file.path document = open(file_handle, "rb") response = HttpResponse(FileWrapper(document), content_type="") response["Content-Disposition"] = ( 'attachment; filename="%s"' % instance.file_name ) return response My endpoint URL is this: {{prod}}api/v1/example/notes/12/?download=file When I call this api, putting local in place of prod, it works and I get a file downloaded, but not in production. Is it something to do with file being closed before getting a response?? -
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) -

Django category dosent show up
Am making a django blog and i got problems with it displaying the posts when they are in categories. I got them to work on category_list.html to show the categories listed. But when you click in on a category you should be able to see the blog posts in that category from the categories.html I got no idea why the category posts dosent show up when you enter a category. anyone got any idea what the problem can be?

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"> … -

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 … -

How do you pass options to Django-flatpickr date picker?
Im trying to implement a datetime picker on a Django app but im having some trouble working out how to pass options to the picker using the django-flatpickr package -->docs here: django-flatpickr. The docs really just get you started but don't go into any detail on how to apply some options and filter provided by the flatpickr.js package. I have successfully implemented the basics with the form fields and passing it to and from the the template which all works fine. However im having difficulty passing options i.e a start date, end date, allowed dates, making sure dates can't be selected I the past etc So the backend: forms.py class DatePickerForm(forms.Form): id = forms.CharField(widget=forms.HiddenInput) date_from = forms.DateTimeField(widget=DateTimePickerInput()) date_to = forms.DateTimeField(widget=DateTimePickerInput()) amount = forms.TypedChoiceField(choices=PRODUCT_QUANTITY_CHOICES, coerce=int) views.py def check_availability(request): #Get date time vals from client, pass to check_availabilty to query db if request.method == 'POST': form = DatePickerForm(request.POST) if form.is_valid(): cd = form.cleaned_data availability = check_availability(cd['id'], cd['date_from'], cd['date_to'], cd['amount']) else: print('Not bloody valid') return HttpResponse(f'Availabilty = {availability}') ClientSide: mytemplate.html <form action="{% url 'check_availability' %}" method="post"> {{ date_form.media }} {{ date_form.as_p }} <input type="hidden" name="id" value="{{ rental.id }}"> {% csrf_token %} <br> <button type="submit" value="Check Dates">Check Availability</button> </form> So what im really looking … -
Exporting tables in Django
I'm trying to export my Table datas. I tried to use django-tables2 but I couldn't did. From documentation I didn't understand much. How can I export my table? my html <!DOCTYPE html> {% load django_tables2 %} <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous"> <title>Admin Page</title> </head> <body> <div class="container"> {% for format in table.export_formats %} <a href="{% export_url 'csv' %}">.{{ format }}</a> {% endfor %} </div> {% render_table table %} </body> </html> 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','barcode', 'full_name','company','email','phone_number','note') And it keep saying no module named django-tables2: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'olvapp', 'tablib', 'django-tables2', ] And When I pip list: django-tables2 2.4.1 -
Django + Django Rest Framework: get correct related objects on intermediate model
I have an intermediate model with the following fields: class UserSkill(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) skill = models.ForeignKey(Skill, on_delete=models.CASCADE, related_name='user_skills') disabled = models.BooleanField(default=False) As you can see, it has two foreign keys, one to the auth user and one to another table called skill. I am trying to get all Skills assigned to an specific user, so I do the following get_queryset in my ViewSet: class AssignedSkillViewSet(viewsets.ModelViewSet): queryset = Skill.objects.all() serializer_class = AssignedSkillSerializer permission_classes = [permissions.IsAuthenticated] def get_queryset(self): user = self.request.user return Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)) Now, I also need to include the intermediate model information in the API, which I can access trough users_skills related name in DRF's Serializer, as follows: class AssignedSkillSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Skill fields = [ 'id', 'url', 'title', 'description', 'user_skills', ] But when I try to get that information it returns ALL user_skills related to the assigned skill, no matter if they are assigned to other users. I need the related model information only for that user and that skill. For Example: If I have a skill named Math, and a user named Maria related_skills = Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)).user_skills.all() The above code will return: [ <UserSkill: Math+Jenniffer>, <UserSkill: Math+Gabriel>, <UserSkill: Math+John>, <UserSkill: Math+Maria>, ] I only … -
Can't Create Django Test Database
I have a django 3.2/mysql 5.7.38 web site that is working. I am trying to write some unit test for the first time, and I am getting an error regarding the creation of the test database.
