Upgrading to Django 3 from Django 2.2.x
I'm trying to upgrade Django 2.2.7 to Django 3. I have an Exception with the load of static library in my template when it's called by tag {% load static from staticfiles %}. Stacktrace: Internal Server Error: / Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/django/template/defaulttags.py", line 1021, in find_library return parser.libraries[name] KeyError: 'staticfiles In the settings.py, staticfiles is config like this: STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ) STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), ] STATIC_URL = '/static/' And when requested by browser, Django answered: 'staticfiles' is not a registered tag library.

DataTable (JQuery): how to switch language with browser language?
I use DataTable in my Django project and currently doing internationalisation of my apps I would like DataTable change with browser language as for my templates. I have found the way to change language with DataTable option var table = $('#table_id').DataTable({ lengthMenu: [5,10], "language": { "url": "//cdn.datatables.net/plug-ins/9dcbecd42ad/i18n/French.json" } }); is their a simple way doing it? or should I test for browser language and have a switch to initialize var table? something like that (pseudocode): if browser.lang == 'english'{ var table = $('#table_id').DataTable({ lengthMenu: [5,10], }); } else { var table = $('#table_id').DataTable({ lengthMenu: [5,10], "language": { "url": "//cdn.datatables.net/plug-ins/9dcbecd42ad/i18n/French.json" } }); }``` -
Post a file to Django REST Framework without Headers/Footers
I am attempting to store a .csv file uploaded to Django REST Framework in its original format. I am following the instructions and the Django REST Framework page for uploading files. When I PUT a .csv file to a defined endpoint I end up waith a file with additional headers and footers. I am trying to save this file into a FileField in its original format so I can run some post-processing steps more easily. Steps I've taken: I created a model to store the file. from django.db import models class OriginFile(models.Model): uploaded_at = models.DateTimeField(auto_now_add=True) file = models.FileField(upload_to="origin_files/") And I created an APIView to handle the upload. from rest_framework import views from rest_framework.parsers import FileUploadParser from rest_framework.response import Response from reference.reference_model.models import OriginFile class OriginFileView(views.APIView): parser_classes = [FileUploadParser] def put(self, request, filename, format=None): f = request.data["file"] load_origin_file = OriginFile() load_origin_file.file.save(filename, f, save=True) return Response(status=204) What I am seeing: The first couple of lines of my original file look like: SPID,SA_ID,UOM,DIR,DATE,RS,NAICS,APCT,0:15,0:30,0:45,1:00,1:15,1:30,1:45,2:00,2:15,2:30,2:45,3:00,3:15,3:30,3:45,4:00,4:15,4:30,4:45,5:00,5:15,5:30,5:45,6:00,6:15,6:30,6:45,7:00,7:15,7:30,7:45,8:00,8:15,8:30,8:45,9:00,9:15,9:30,9:45,10:00,10:15,10:30,10:45,11:00,11:15,11:30,11:45,12:00,12:15,12:30,12:45,13:00,13:15,13:30,13:45,14:00,14:15,14:30,14:45,15:00,15:15,15:30,15:45,16:00,16:15,16:30,16:45,17:00,17:15,17:30,17:45,18:00,18:15,18:30,18:45,19:00,19:15,19:30,19:45,20:00,20:15,20:30,20:45,21:00,21:15,21:30,21:45,22:00,22:15,22:30,22:45,23:00,23:15,23:30,23:45,0:00 5001,5001,KWH,R,05/20/2018,A6,722000,100.0,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000200,0.022600,0.058100,0.100500,0.148500,0.251400,0.295800,0.359500,0.321400,0.365300,0.509800,0.571900,0.734700,1.121900,1.312700,1.358400,1.573900,1.270300,1.512500,1.359400,1.735500,1.759900,1.806400,1.501400,1.343900,1.396900,1.660400,1.924500,2.074300,2.037100,1.409000,1.371600,1.646600,1.591100,1.674500,1.751400,1.366200,1.404300,1.449400,1.405700,1.197900,0.679400,0.793800,0.772400,0.768200,0.969800,0.967400,0.833900,0.623500,0.474100,0.446600,0.368700,0.233500,0.133600,0.043800,0.011100,0.000300,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000 The first handful of lines of the stored file look like: ----------------------------434117419534676393692068 Content-Disposition: form-data; name="file"; filename="filename.csv" Content-Type: text/csv SPID,SA_ID,UOM,DIR,DATE,RS,NAICS,APCT,0:15,0:30,0:45,1:00,1:15,1:30,1:45,2:00,2:15,2:30,2:45,3:00,3:15,3:30,3:45,4:00,4:15,4:30,4:45,5:00,5:15,5:30,5:45,6:00,6:15,6:30,6:45,7:00,7:15,7:30,7:45,8:00,8:15,8:30,8:45,9:00,9:15,9:30,9:45,10:00,10:15,10:30,10:45,11:00,11:15,11:30,11:45,12:00,12:15,12:30,12:45,13:00,13:15,13:30,13:45,14:00,14:15,14:30,14:45,15:00,15:15,15:30,15:45,16:00,16:15,16:30,16:45,17:00,17:15,17:30,17:45,18:00,18:15,18:30,18:45,19:00,19:15,19:30,19:45,20:00,20:15,20:30,20:45,21:00,21:15,21:30,21:45,22:00,22:15,22:30,22:45,23:00,23:15,23:30,23:45,0:00 5001,5001,KWH,R,05/20/2018,A6,722000,100.0,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000200,0.022600,0.058100,0.100500,0.148500,0.251400,0.295800,0.359500,0.321400,0.365300,0.509800,0.571900,0.734700,1.121900,1.312700,1.358400,1.573900,1.270300,1.512500,1.359400,1.735500,1.759900,1.806400,1.501400,1.343900,1.396900,1.660400,1.924500,2.074300,2.037100,1.409000,1.371600,1.646600,1.591100,1.674500,1.751400,1.366200,1.404300,1.449400,1.405700,1.197900,0.679400,0.793800,0.772400,0.768200,0.969800,0.967400,0.833900,0.623500,0.474100,0.446600,0.368700,0.233500,0.133600,0.043800,0.011100,0.000300,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000 And the last couple of lines of the stored file look like this. 5090,5090,KWH,D,11/04/2018,A6,713910,104.2,0.333000,0.319000,0.332000,0.309000,0.326500,0.321000,0.322500,0.320000,0.296000,0.322000,0.323000,0.334000,0.321000,0.334000,8.098000,7.043000,1.422000,0.322000,0.323000,0.335000,0.322000,0.322000,0.322000,0.334000,0.336000,0.340000,0.392000,0.584000,0.200000,0.054000,0.176000,0.156000,0.090000,0.000000,0.002000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.002000,0.001000,0.009000,0.014000,0.020000,0.032000,0.054000,0.055000,0.086000,0.127000,0.151000,0.168000,0.220000,0.245000,0.299000,0.282000,0.317000,0.328000,0.314000,0.327000,0.315000,0.328000,0.316000,0.328000,0.318000,0.323000,0.328000,0.319000,0.327000,0.325000,0.320000,0.332000,0.319000,4.420000,3.531000,2.584000,0.458000,1.001000,0.263000,0.263000,0.261000,0.260000,0.258000 ----------------------------434117419534676393692068-- Is there a way … -

How to create model objects of one model automatically when a model object of another has been added in django
Say for example I have a Model called Player. I want Model objects of Player created when new Users are added in django (from django.contrib.auth.models.User) such that each User object in User model has its own object in Player model. I know that I would technically have to use models.ForeignKey() to create a field in Player model and relate it to the User model and that I don't have to worry about deletion of users if I use the on_delete=models.CASCADE parameter in models.ForeignKey() but how do I automatically create these objects with like default values and such. Initially this was my code to do so: for name in User.objects.all().values_list('username', flat=True): if name not in Player.objects.all().values_list('player_name', flat=True): new_player = Player(player_name=name, current_level_no=None, no_of_moves=None) new_player.save() else: pass But this would give me a DatabaseIntegrityError that "Models aren't loaded yet". So I am confused about what to do or how to go forward. As always, I greatly appreciate all answers! -
Django POST error: tuple has no attribute get, despite similar code working previously
I'm working on a page that autofills an html dropdown with data from a Django model, then on submit, sends that data to another page that will do things with it. I have the html dropdown populated, but am having issues POSTing to another page. I keep getting "AttributeError at /battleSim/ 'tuple' object has no attribute 'get' as my error despite similar code working in my characterCreator template. I get this error as soon as I attempt to navigate to battleSim.html on the development server, despite the fact it shouldn't be trying that until a POST method runs. (I think?)

Simple operations with data requested from a Django model
I am trying to write a simple web application, where i can upload csv files and return the headers from each file. Everything is working fine. The id, the path to the file, gets saved in a database. This is the response i am getting: { "id": 1, "filefield": "http://127.0.0.1:8000/api/merged/1/uploads/header_body_test_zZr4Cea.csv" } What i do not understand is, where or how can i actually work with the data i request from the database? What i am imagining is a different url route, where i can specify an id and the response would be something like this: { "id": 1, "filefield": "http://127.0.0.1:8000/api/merged/1/uploads/header_body_test_zZr4Cea.csv" "headers_of_csv": "Date;Amount" } Its hard for me to explain (or google) what my problem actually is.

This is how I filter items based on user selection: This is the ListView, get_queryset I've a condition to use the captured filter_val: class CatalogoListView(ListView): model = UnitaryProduct template_name = "shop/catalogo.html" paginate_by = 10 def get_queryset(self): filter_val = self.request.GET.get('filtro', 'todas') order = self.request.GET.get('orderby', 'created') if filter_val == "todas": context = UnitaryProduct.objects.all().filter(available=True).order_by('-created') return context else: context = UnitaryProduct.objects.filter( subcategory2=filter_val, ).filter(available=True).order_by('-created') return context def get_context_data(self, **kwargs): context = super(CatalogoListView, self).get_context_data(**kwargs) context['filtro'] = self.request.GET.get('filtro', 'todas') context['orderby'] = self.request.GET.get('orderby', 'created') context['category'] = Category.objects.get(slug="catalogo") context['total_stickers'] = UnitaryProduct.objects.all().count() return context I've tried to put add stickers_por_categoria to the queryset but nothing gets rendered in template: def get_queryset(self): filter_val = self.request.GET.get('filtro', 'todas') order = self.request.GET.get('orderby', 'created') if filter_val == "todas": context = UnitaryProduct.objects.all().filter(available=True).order_by('-created') return context else: context = UnitaryProduct.objects.filter( subcategory2=filter_val, ).filter(available=True).order_by('-created') context['stickers_por_categoria'] = UnitaryProduct.objects.filter( subcategory2=filter_val, ).filter(available=True).order_by('-created').count() return context template: <div class="margin-bottom5"> <h2> Actualmente contamos con {{ total_stickers }} stickers en nuestro catálogo</h2> <span>Revisa todos utilizando nuestro filtro por categoría y … -

Django - What are the advantages and disadvantages of using unique_togueter vs. using a queryset in the view?
Suppose we have the next model: class Publications(models.Model): author = .......... post = .......... and we don't want duplicate records to be stored in the database. This could be done with unique togheter on the model: Meta: unique_together = (author, post) or it could be done in the view with something like: register_exist = Publications.objects.filter(...).exists() if register_exist == False: #Code to save the info What are the advantages or disadvantages of using these methods? -
Django 2.2.6 (Python 3.6) + Apache + Ubuntu 18.04.3 error
I made a django project and I tried deploying it with apache and wsgi, however I'm getting the following error in error.log: Current thread (most recent call first): [Wed Dec 04 17:14:02. 2019] [core:notice] [pid :tid ] AH00051: child pid 27347 exit signal Aborted (6), possible coredump in /etc/apache2 Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings' I'm using python 3.6.9, I've installed every necessary library using pip3 and I've installed ibapache2-mod-wsgi-py3 using apt.

What is the correct way to get translations from Django's *.po/mo files?
Currently I activate each language and then use ugettext but it looks ugly. from django.conf import settings from django.utils.translation import activate, ugettext # settings.LANGUAGES looks like: settings.LANGUAGES = [ ('en', 'English'), ('ru', 'Russian') ] class Profile(models.Model): ACTIVE = 1 INACTIVE = 2 CLOSED = 3 PROFILE_STATUS_CHOICES = ( (ACTIVE, _('Active')), (INACTIVE, _('Inactive')), (CLOSED, _('Closed')), ) def choices_serialize(choices): """ Convert choices to format suitable for Front End's tree-select. :param choices: :return: [{'id': 1, 'text': {'en': 'Active', 'ru': 'Действующий'}}, {'id': 2, 'text': {'en': 'Inactive','ru': 'Недействующий'}}, {'id': 3, 'text': {'en': 'Closed', 'ru': 'Закрыт'}}] """ data = {} for lang in [t[0] for t in settings.LANGUAGES]: activate(lang) for choice in choices: data.setdefault(choice[0], {}) data[choice[0]].setdefault(lang, ugettext(choice[1])) return [{'id': k, 'text': v} for k, v in data.items()] choices_serialize(Profile.PROFILE_STATUS_CHOICES) Is there a better approach? -
Parse Data into HTML Bootstrap modal (Django)
I have downloaded a bootstrap theme. In one of the HTML documents there is a modal. Basically a Popup that contains like a detail page. My question is how I can parse data into that detail page from the specific object I tapped. So some kind of id. Before I used to have the detail page on a separate page. Through a URL I did this: {% url 'URL' object.id %}. This is a part of the modal and lets say I want to change the modal-title depending on the object.id: <div class="modal modal-task" id="task-modal" tabindex="-1" role="dialog" aria-hidden="true"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Create Brand Mood Boards</h5> This is the loop of cards, all with different urls: When I tap one the detail pop-up shows. And I want the data of that card inside the pop-up. like a detail view: <div class="modal modal-task" id="task-modal" tabindex="-1" role="dialog" aria-hidden="true"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Create Brand Mood Boards</h5> Here are the cards: This is the pop-up: -
How to require dependent drop down whenever there are options to choose from in Django?
I have a form with a dependent drop-down. Currently, I have it set so that the second drop-down only appears if there are options available in it, otherwise is hidden. What I am having trouble with is that, whenever you choose a primary(Work Area) option that has a secondary(Station) drop-down, you can submit the form without having selected an option from the dependent (secondary) drop-down, which is supposed to be required whenever there are options in it. How can I modify this so that the dependent drop-down is required whenever it appears? models.py class WorkArea(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name class Station(models.Model): work_area = models.ForeignKey(WorkArea, on_delete=models.CASCADE, related_name="stations") name = models.CharField(max_length=50) def __str__(self): return self.name class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): employee_number = models.ForeignKey(Salesman, on_delete=models.SET_NULL, help_text="Employee #", null=True, blank=False) work_area = models.ForeignKey(WorkArea, on_delete=models.SET_NULL, null=True, blank=False, help_text="Work Area", related_name="work_area") station_number = models.ForeignKey(Station, on_delete=models.SET_NULL, null=True, help_text="Station", related_name="stations", blank=True) forms.py class WarehouseForm(AppsModelForm): class Meta: model = EmployeeWorkAreaLog widgets = { 'employee_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('employee_number').remote_field, site, attrs={'id':'employee_number_field'}), } fields = ('employee_number', 'work_area', 'station_number') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['station_number'].queryset = Station.objects.none() if 'work_area' in self.data: try: work_area_id = int(self.data.get('work_area')) self.fields['station_number'].queryset = Station.objects.filter(work_area_id=work_area_id).order_by('name') except (ValueError, TypeError): pass elif self.instance.pk: self.fields['station_number'].queryset = self.instance.work_area.stations.order_by('name') views.py def enter_exit_area(request): enter_without_exit = … -

See all the items created by the logged in user
novice here trying to get an ebay style e-commerce project finished! When a user checks their profile, I want it to list all the items they have for sale. The owner in the Item model stores the username, so, essentially, I want to check the owner field of all items, then pull the ones that are == username. Here's the code I got so far: views.py def user_profile(request): """The users profile page""" user = User.objects.get(email=request.user.email) user_items = Item.objects.filter(owner__icontains=request.GET[user]) return render(request, 'profile.html', {"profile": user, "items": user_items}) I'm then using {% for item in user_items %} in the html. Apologies if this is an easy one, but I'm struggling to get this right. -
