How to filter multiple similar data in python/django?
access I can get all the emails with access_membership but what if I only want to save unique emails(i.e the scenario is I have added an email to access = "tester4@testing.inc" and I can still add "tester4@testing.inc" ) I would like to prevent saving an email that was already added in the database. Is this the right code for that? "Access_Membership.objects.filter(member_email=request.user.email).exists()" how do I use this and where should I put it? views.py def give_access(request, user_pk, arb_pk): arbitration = Arbitration.objects.get(pk=arb_pk) form_kw = {'user':request.user, 'arb_pk':arb_pk} AccessInvitationFormset=inlineformset_factory(Arbitration, Access_Membership, form = AccessMembershipForm, extra=1, can_delete=False) ctx = {'form_url' : reverse("giveaccess", args=[user_pk, arb_pk])} dict = {'mytype': 'access', } snip_tpl = 'app/snippets/new_access_section.html' if request.method == "POST": formset = AccessInvitationFormset(request.POST, form_kwargs=form_kw, prefix="A", instance=arbitration) else: formset = AccessInvitationFormset(queryset = Access_Membership.objects.none(), form_kwargs=form_kw, prefix="A", instance=arbitration) return save_new_members(request, user_pk, arb_pk, formset, ctx, dict, snip_tpl) new_access_section.html {%for tm in arbitration.access_membership_set.all%} <tr> {%if tm.member%} … -
Reuse django form for insert and delete
I'm making a form to add and delete some items form an items Model. The thing is i would like to know if i can use the same form for this. I want to use the form once to add to the database and then, coming from a different url, to be able to choose from a dropdown which items to delete from the database. forms.py for idea: class CategoryForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.current_url = kwargs.pop('current_url') super(CategoryForm,self).__init__(*args,**kwargs) self.helper = FormHelper() self.helper.form_method = 'POST' self.helper.add_input(Submit('submit', 'Submit', css_class='btn-success')) if 'delete' in self.current_url: self.fields['section'].widget = forms.HiddenInput() here i would like to pass the Category objects so they can be shown in the dropdown. something like: self.fields['name'].widget = forms.Select(Category.objects.all()) class Meta: model = Categories fields = '__all__' I don't know what is the best practice for this or how it's usually done. -
Alternate key lookup with Django Rest Framework
I have the following viewset: class ProductViewSet( mixins.RetrieveModelMixin, viewsets.GenericViewSet): ... This provides me with endpoint for fetching a product by ID: /products/{id} I'm trying to add another endpoint for fetching a product with secondary unique key: /products/uuid/{product_uuid} How can I achieve this with DRF? I'm using DRF 3.8.2 and Django 1.11. Is it somehow possible to make @action() decorator provide this? Its basic behaviour does not solve the problem as it only provides urls of pattern /products/{id}/detail or /products/detail. -

Django syntaxError when starting django project in virtualenv with python 3
A question very similar to this one already exists, but it is regarding python2. In another related question the user did not activate their virtual environment. I did.

radio buttons and filter in Django
Django==1.11 I want to create a filter in a task app it will a radio button - my task or me task and displayed will be all tasks. tasks_list = Task.objects.all().filter( Q(executive_man=request.user) | Q(author=request.user)).order_by( '-created_date') The code show all task. executive_man=request.user - if first button, author=request.user - the second button. And I do not understand how it to do. I now read http://django-filter.readthedocs.io/en/master/index.html but if I right to understand the library use our models, right? But me not need the models. I know ORM and know how to show the data in HTML. form = WhoTask(request.POST or None) if form.is_valid(): who = form.cleaned_data['tasks'] if who == 'me': tasks_who = tasks_list.filter(executive_man=request.user) return render(request, 'task/task_list.html', {'filter_category': tasks_filter, 'form': form, 'task_who': tasks_who}) elif who == 'my': tasks_who = tasks_list.filter(author=request.user) return render(request, 'task/task_list.html', {'filter_category': tasks_filter, 'form': form, 'task_who': tasks_who}) else: pass return render(request, 'task/task_list.html', {'filter_category': tasks_filter, 'form': form}) This views without django-filter library but I don't see data in HTML, I think the error in return because if I print who I see a selection in the terminal. I hope you will help me to understand how to implement the filter. Thank you very much. -

Run command only once after Django app startup
I have a django-based function that needs to be run only once in Django, when the app boots up. The tricky part is that: The code in question heavily uses django ORM, so apps have to be ready at that point, The code should run only once - e.g. not once per every worker, but exactly once per "website" (regardless of whether it's deployed via gunicorn with a dozen of workers, or run locally via the built-in development web-server), The code should only run once the app boots, but NOT by running other management commands. The code can take a while to complete, and I don't want it to trigger each time I run makemigrations or shell. I could, theoretically, just introduce a locking mechanism and let it run somewhere in AppConfig.ready() method, but that would still run in all management commands as well. Since the app is packaged in Docker, I've been also thinking about simply wrapping the code in a separate management command and running it in the entrypoint, just before the app is being started. That seems to do the trick, but it will be done automatically only in that particular container - if somebody runs a … -

504 error when the view loading takes more than 5 s
I've got an installation with django-nginx-gunicorn-supervisor-postgresql. In the django admin I've got a 504 if the loading of the view takes more than around 5 seconds. For instance, if I filter a changelist view with many records and takes more than that time the 504 appears. The same view with less records works, as long as it takes less time. I've noticed also that some views are still running in background, even after the 504, cause I can see the modifications they make in database after they finish. I've tried to increase all timeouts I've found (nginx, gunicorn), but none of them were configured to 5 seconds. Any guess of what could be misconfigured? Or where could be the timeout that raises the 504? Thanks -

I'm looking to send an email to the user,once banned with a list of reasons from the report_reasons field as to why they have been banned. def banning_users(self, request, queryset): for obj in queryset: if hasattr(obj, 'user'): # This object is a Profile, so lookup the user profile = obj user = obj.user user.is_active = False user.save() banned_reasons = [] banned_user = profile.banned_profile.create(profile=profile) reports = banned_user.profile.user_reported_report.all() banned_user.save() for report in reports: banned_user.report_reason.add(report) # Send the email subject = 'Ban' message = 'You have been banned for the following reasons: []' email_from = settings.EMAIL_HOST_USER recipient_list = [user.email] send_mail( subject, message,email_from, recipient_list) self.message_user(request, "User is banned and Email has been sent") -
Django : How to upload csv file in unit test case using APIClient
I would like to write a unit test for a view on a Django REST Framework application. The test should upload a CSV file using the POST. @staticmethod def _file_upload(client, string, args, file_name): base_path = os.path.dirname(os.path.realpath(__file__)) with open(base_path + file_name, 'rb') as data: data = { 'file': data } response = client.post(reverse(string, args=[args]), data, format = "multipart") return response.status_code, response.data The above code I used which obviously doesn't work it shows the following error Missing filename. Request should include a Content-Disposition header with a filename parameter. The following code is the one that I want to test via unit testing. class ChartOfAccounts(views.APIView): parser_classes = (JSONParser, FileUploadParser) def post(self, request, pk, *args, **kwargs): request.FILES['file'].seek(0) csv_data = CSVUtils.format_request_csv(request.FILES['file']) try: coa_data = CSVUtils.process_chart_of_accounts_csv(company, csv_data) serializer = CoASerializer(coa_data, many=True) if len(serializer.data) > 0: return Utils.dispatch_success(request, serializer.data) except Exception as e: error = ["%s" % e] return Utils.dispatch_failure(request, 'DATA_PARSING_ISSUE', error) Any help regarding this is welcome. Thanks in advance -
