Problem with serializers creating an API with Django
I am writing an API with django and I am having this problem: When I create a serializer object, if I do it like this: document_serializer = DocumentSalesforceSerializer(data={ "AccountId": patient_id, "ContactId": patient_id, "Proveedor__c": "docline", "Servicio_asociado__c": "report", "Mapfre_Id__c": patient_id, "Status": "In Progress", "StartDate": document["createdAt"], "EndDate": "hoy", "Subject": document["category"], "Description": description, "SAV_fld_source__c": "docline", "SAV_fld_doclineExtId__c": id, "SAV_fld_doctor__c": "", }) document_serializer.is_valid(raise_exception=True) I get the following error: The translation infrastructure cannot be initialized before the apps registry is ready. Check that you don't make non-lazy gettext calls at import time. Reading on the internet some people said that I whould delete the data= part, so I left it like this: document_serializer = DocumentSalesforceSerializer({ "AccountId": patient_id, "ContactId": patient_id, "Proveedor__c": "docline", "Servicio_asociado__c": "report", "Mapfre_Id__c": patient_id, "Status": "In Progress", "StartDate": document["createdAt"], "EndDate": "hoy", "Subject": document["category"], "Description": description, "SAV_fld_source__c": "docline", "SAV_fld_doclineExtId__c": id, "SAV_fld_doctor__c": "", }) document_serializer.is_valid(raise_exception=True) But then I am getting this error: Cannot call `.is_valid()` as no `data=` keyword argument was passed when instantiating the serializer instance. Does anyone have and idea of what is causing the error? Thanks in advance for reading this question. -

Send a zip file as a response using python
This is probably a question already asked but posting it again since I didn't find a way to resolve my issue. I am given a zip file that I need to send to UI from where it should be downloaded for the user. While testing on POSTMAN, using Send & Download button associated with POST, I am able to download the file. But when opening it, it says: Windows cannot open the folder. The Compressed(zipped) folder <zip path> is invalid Here's the code I am trying: from django.response import Response from rest_framework.views import APIView def get_response(): with open(zip_file_path.zip, 'r', encoding='ISO-8859-1') as f: file_data = f.read() response = Response(file_data, content_type='application/zip') response['Content-Disposition'] = 'attachment; filename="ReportTest.zip"' return response class GenerateZIP(APIView): def post(self, request): zip_file_response = get_response() return zip_file_response The zip file read is valid as it's already on the local. Any ideas? -
form-data(POSTMAN) only showing "This field is required" in django
I have 2 models - Module and Room. A module can have zero or multiple rooms and a room can be added into multiple modules. So, there is a simple many-to-many relationship between them.

How to display a value in another table by using a function in django
I have been trying to make search_fields able to search for fields in another table on the django admin page.

Key 'fieldname' not found in 'ModelForm'. Django 3.2
I am trying to override the get_form function in admin class in Django 3.2. I defined a custom permission for a specific user that can only view some defined fields of a model. It worked fine but when I tried to navigate to the change form of an object with the non-permitted users, I cannot be able to view the change form as superuser until other user closes the change form. So basically, override get_form method is not working at the same time for different kind of users. By the way I did not have any defined view because I am only using admin template as view, I am just only overriding admin template. I am new in django so I don't know that I am doing this correctly... Here is the admin class that I created and override get_form method(for instance I do not want to display surname if the user does not have the custom permission): class HumanAdmin(admin.ModelAdmin): fieldsets = ( ('Fields 1', {'fields': ('id','name', 'surname'),}), ) def get_form(self, request, obj=None, **kwargs): if request.user.has_perm('app_name.custom_permission'): self.fieldsets[0][1]["fields"] = ('id','name', 'surname') form = super(InventoryAdmin,self).get_form(request, obj, **kwargs) else: self.fieldsets[0][1]["fields"] = ('id','name') #I do not want to see if user does not have … -
DRF Pagination custom response without model APIView
Hello I have a project in Django, which performs several queries to different databases returning them in several endpoints, for this I use Pandas and DRF (APIViews). The problem arises when the response is very long and logically the server runs out of memory, I understand that I need to paginate the result but I have not found the way to do it because I do not use models or serializers, I do raw queries with pandas to make the queries. Is there any way to paginate the results the way I'm doing it? I leave some snippets of my code. class AffiliateAPIView(APIView): permission_classes = (IsAuthenticated,) def get(self, request): insurance = self.request.query_params.get('insurance', None) emergensys_df = pd.read_sql_query(general_attention(insurance), engine()) return Response(emergensys_df.to_dict(orient='records')) -
Dynamic ModelChoiceField on template
I would like to have a ModelChoiceField that is dynamically changed by the user directly on the form. Basically I'm building a CMS and User has several templates at its disposal, however I'd like to display in my dropdown only the relevant templates to the kind of content it's producing. For example, we would have a first dropdown to select the content_type. We assume we pick article. Selecting this would update in a second dropdown list both including side_image_article.html and default_article.html. Here is a MRE : models.py class MyTemplate(models.Model): template_name = models.Charfield(max_length=80) content_choices = [("article", "article"), ("project", "project"), ("press_release", "press_release"), ("newsletter", "newsletter"), ("newsletter_web", "newsletter_web"), ("petition", "petition"), ("mailing_list_signup", "mailing_list_signup"), ] content_type = models.CharField(max_length=100, choices=content_choices, default="article") Each template is assigned a content type that is appropriate to the sort of content it's designed for. still models.py class MyBlogitem(models.Model) template = models.ForeignKey(MyTemplate, on_delete=models.PROTECT) body_text = models.TextField() content_choices = [("article", "article"), ("project", "project"), ("press_release", "press_release"), ("newsletter", "newsletter"), ("newsletter_web", "newsletter_web"), ("petition", "petition"), ("mailing_list_signup", "mailing_list_signup"), ] item_type = models.CharField(max_length=100, choices=content_choices, default="article") And the forms.py class MyBlogItemForm(ModelForm): template = ModelChoiceField( queryset=TopicBlogTemplate.objects.filter( content_type=???), empty_label=None) So here the goal would be to filter the template field using the content_type field, both being in dropdown lists.

Sentry SDK Django set tag for event and raise
This is the current implementation I have: from sentry_sdk import push_scope def run(): with push_scope() as scope: message = "Failed" scope.set_tag("custom", "tag") raise Exception(message) But according to the docs the with-scope context manager will swallow the exception raised inside. The problem is I need this method run to actually raise an Exception so is doesn't send a response to the user. If I handle the flow and capture the sentry event in the with-scope context manager and raise later outside of the context manager, I will end up with duplicate events in Sentry ? from sentry_sdk import push_scope, capture_exception def run(): with push_scope() as scope: message = "Failed" scope.set_tag("custom", "tag") capture_exception(message) raise Exception(message) Is this really sending two events to Sentry and/or is there a better way to deal with this issue, maybe forcing sentry to ignore the raise at this point ? -

Publish and "Save Drafts" feature in Django
I am working on a Django Rest Framework B2B application with a React Frontend. The data is fed from a csv and then Analytics dashboards are rendered in React. Each Account ("User") is a company - and within a company, the app is used by the entire marketing team (say). Each company account has data unique to that co. and dashboard preferences unique to that company. An administrator is a human user who is some Manager / employee of a company (let's say, for example, Boeing, Nike etc) who has edit / administrator rights on behalf of the company. That "admin" makes some changes to the dashboard preferences and wants to "Publish" the changes so that rest of the employees (the rest of the Marketing team) of the company Account can view the updated dashboard. But maybe not yet, hence a "Save Drafts" feature. I'm not sure how to get these two features in the most industry-standard way in Django (DRF) - When I hit "Publish", the entire marketing team should be able to see the changes. (It's a B2B app). But when I save drafts, I should be able to view the changes (as admin) but not the rest … -

Is it possible to return a GET request after saving the post request to the database?
I have been trying to return the GET response after the post request has been made and the data has been saved to the DB. Instead of the serialized validated data being returned to the api caller. It would save another GET request handling on the frontend Here are the serializers: class PollVoteSerializer(serializers.ModelSerializer): class Meta: model = PollVote fields = '__all__' class PollAnswerSerializer(serializers.ModelSerializer): is_correct_answer = serializers.SerializerMethodField() answer_votes = serializers.SerializerMethodField(read_only=True) class Meta: model = PollAnswer fields = ('id', 'answer', 'is_correct_answer', 'answer_votes', ) def get_is_correct_answer(self, object): if object.question.is_finished: return object.is_correct return False def get_answer_votes(self, object): return object.answer_vote.count() class PollQuestionSerializer(serializers.ModelSerializer): choices = PollAnswerSerializer(many=True, read_only=True) total_votes = serializers.SerializerMethodField(read_only=True) user_voted = serializers.SerializerMethodField(read_only = True) class Meta: model = PollQuestion fields = ['id', 'question_name', 'created_by', 'is_finished', 'total_votes','user_voted', 'choices', ] def get_total_votes(self, question_vote): c = PollVote.objects.filter(question=question_vote).count() return question_vote.question_vote.all().count() def get_user_voted(self, object): user_id = self.context['request'].user.id return PollVote.objects.filter(question__id = object.id, voted_by = user_id).exists() Here is the view. class GetPoll(viewsets.ModelViewSet): def get_serializer_class(self): if self.action == 'create': return PollVoteSerializer else: return PollQuestionSerializer queryset = PollQuestion.objects.all().order_by('-id') authentication_classes = (authentication.TokenAuthentication,) permission_classes = [IsAuthenticated] pagination_class = StandardResultsSetPagination Apologies for the massively unneat formatting.

Making Django Function Work On HTML On Button Click
I'm trying to call a view so that it displays within a div on the page I already have existing rather than linking to a new page to post a comment. So far I've been able to bring up the div which shows after a button click and hides when pressed again. Ideally, when it shows the form for a comment should show yet at the moment it is only the submit button. I'm wondering how I could get this form to show up in this div as it does on the other HTML page. If there is any more required info let me know, just didn't want to give too much to look at. Views.py: class AddCommentView(CreateView): model = Comment form_class = CommentForm template_name = 'storysharing/comment.html' def form_valid(self, form): form.instance.story_id = self.kwargs['pk'] return super().form_valid(form) def get_success_url(self): return reverse('storysharing:story_details', kwargs={'story_id':self.kwargs['pk']}) urls.py: app_name = 'storysharing' urlpatterns = [ path('', views.index, name = 'index'), path('<int:story_id>/', views.story_details, name = 'story_details'), path('add_story/', views.add_story, name = 'add_story'), path('thanks/', views.story_added, name = 'story_added'), path('final_post/<int:pk>', UpdateStoryView.as_view(), name = 'final_post'), path('review/', views.review, name = 'review'), path('get_location/', views.get_location, name = 'get_location'), path('<int:pk>/comment', AddCommentView.as_view(), name = 'comment'), ] page.html, the tag is where the link usually links to the other … -
Django. Как в шаблоне узнать наличие значения в QuerySet
Всем привет! Есть две связанные модели, вопрос и ответ от пользователя: models.py class TasksModel(models.Model): title = models.CharField('Заголовок задания', max_length=100) description = models.TextField('Описание') class UserAnswerTasks(models.Model): task_id = models.ForeignKey(TasksModel, verbose_name='id задания', on_delete=models.CASCADE) user_id = models.ForeignKey(ProjectUsers, verbose_name='id пользователя', on_delete=models.CASCADE) answer = models.TextField('Ответ на задание') Представление: views.py def index(request): user = request.user # берём пользователя tasks = TasksModel.objects.all() # Берём все вопросы all_answers = UserAnswerTasks.objects.filter(user_id=user) # Берём все ответы от этого пользователя content = { "tasks": tasks, "all_answers": all_answers } return render(request, 'tasksapp/index.html', content) Далее мне нужно в index.html вывести все вопросы из "tasks", и к ним же создать кнопку что если вопрос уже решён пользователем то "Кнопка 1" если пользователь ещё не решил этот вопрос то "Кнопка 2" index.html {% for i in tasks %} <h2"> <a href="{% url 'tasks:task' i.pk %}">{{ i.title }}</a> </h2> ???И ВОТ ТУТ КАК СДЕЛАТЬ ВЫДАЧУ??? {% if i.id in all_answer %} <a href="" class="btn">Посмотреть свой ответ</a> {% else %} <a href="" class="btn">Приступить к заданию</a> {% endif %} {% endfor %} Проходить снова циклом не хочется по all_answer, знаю что тип данных разный для оператора in, я знаю как решить задачу ещё одним циклом по all_answer.

Django custom decorator for redirections
I'm deploying a multi-domain platform in Django, with some model logic for performing redirections between websites. As the redirection mapping is going to get slightly bulky I'd rather decorate each view as opposed to replicate the code for redirections in every view (I'm sticking to function-based views for this project). As the logic could possibly be changed too, I need to have it all in one place and I'd really like to use a custom decorator for that. I've been trying different syntaxes in order to define a decorator and I'm getting all sorts of problems. https://pythonbasics.org/decorators/ I'm using the syntax I see here but I couldn't apply it to Django views at first. I'm using Django 3.2. This is the thread that most resambles my situation and which helped me get closer to the result I want Django custom decorator redirect problem however my decorator view still returns None instead of an HttpResponse object and I don't understand. Decorator 1 def inner(request, *args, **kwargs): print("DEBUGGING") if settings.DEBUG == False or request.user.is_superuser == False: return render(request, 'myapp/manutenzione.html') func(request, *args, **kwargs) return inner Decorator 2 for my redirection def reindirizzamenti_necessari(func): def inner(request, *args, **kwargs): print("REINDIRIZZAMENTI") sito = get_current_site(request) dominio = sito.domain …
