Processing process and UniqueConstraint Django
I did model with constraints: class DiscountSchema(models.Model): ... class Meta: verbose_name = "DiscountSchema" constraints = [ constraints.UniqueConstraint( fields=( "level", "level_value", "discount_rate", "background_col", "foreground_col", "loyalty_card", ), violation_error_message="UNIQUEERROR", name="Uniqueschema", ) ] How can I process this constraints when I create instance in serializer? Now I have: try: serializer.is_valid(raise_exception=True) return serializer.save() except IntegrityError as e: if "Uniqueschema" in e.args[0]: pass else: raise e Is there better way? -
How to design a separate authentication server using the ROPC OAuth2 flow?
I have to implement a separate authentication server using OAuth. The tech-stack that I am using is django and graphQL. As I am maintaining a separate server for authentication, I have created two django projects that run on two different ports, one for the authentication and the other as a resource server to perform CRUD operations on the user model. But since I have to authenticate the user using username and password and should issue access tokens, should I define the 'user' model in the project module which is dedicated for the authentication server? But if I am creating the 'user' model on the authentication server side, every time when the user requests for some information, my resource server needs to make a request to the authentication server to get that information. Is this a common practice? I have tried creating views in my authentication server, as in '/register' and '/verifytoken'. The resource server will place POST requests to these views using graphQL while registering the user and also while trying to access aa protecrted resource to verify the access token. But since I am using /register and /verifytoken routes, does it come under using REST API? If yes, how … -
Django models migration gives an error on a table that does not exist
I am making a project using Django with Django models (SQLite). I applied some changes to my models but when migrating it was giving me the following error: ValueError: Field 'id' expected a number but got 'FAL'. I commented out the changes and tried to re-migrate however despite I removed the changes it still gives me the same error. This is my models.py (including the commented out changes): from django.db import models from django.utils import timezone # Create your models here. # BOROUGHS = [ # ("GRE", "Greenwich"), # ("BEX", "Bexley"), # ("LEW", "Lewisham"), # ("HOM", "Homerton"), # ("OOB", "Out of borough") # ] # SPECIALITIES = [ # ("CAR", "Cardiology"), # ("COE", "Geriatric"), # ("PED", "Paediatric"), # ("ONC", "Oncology"), # ("ORT", "Orthopaedic"), # ("NEU", "Neurology"), # ("RES", "Respiratory") # ] # REASONS = [ # ("FAL", "Fall"), # ("NEU", "Neuro"), # ("GEN", "Generally unwell"), # ("MEH", "Mental health"), # ("ORT", "Orthopaedic"), # ("RES", "Respiratory") # ] # LOCATION = [ # ("HOM", "Home"), # ("WAR", "Ward"), # ("ICB", "Rehab unit"), # ("PLC", "Placement") # ] # class Doctor(models.Model): # name: models.CharField(max_length=50) # speciality: models.CharField(max_length=50, default="COE") # class AdmissionReason(models.Model): # reason: models.CharField(max_length=50, default="FAL") # class Borough(models.Model): # Borough: models.CharField(max_length=20, default="GRE") … -
Django context processor code not working
I am trying to use context_processors.py to show the number of unread_messages on my base.html message icon, but for some reason it is not working. While the unread_message counter is working for the user_messages_view properly, it just won't work for base.html. I tried changing the logic of my context_processors.py, but same result.

Django IntegrityError: How to handle ForeignKeyViolation in a delete view?
I’m facing an issue when trying to delete records in Django. I have a delete function for companies, but sometimes I encounter an IntegrityError if the company has related records in another table. I tried handling the IntegrityError, but it doesn’t help—the error occurs after the try-except block and results in a 500 error. Here’s my code: @login_required(login_url=reverse_lazy('autintification')) def delete_cp_company(request): db_name = LOCAL_DB if DEBUG else request.get_host().split(".")[0] cp_company_ids = json.loads(request.POST.get('cp_company_ids')) no_del = [] for ids in cp_company_ids: company = CP_company_for_pattern.objects.using(db_name).get(id=ids) print('id', ids) try: company.delete() except: no_del.append({ 'id': company.id, 'name': company.com_name, }) return JsonResponse(data={'no_delete': no_del}) Here’s the JavaScript that sends the delete request: function delete_cp_company() { let check_box = $('.cp_company_list_block .check_for_choose_item'); let ids_to_delete = []; for (let i = 0; i < check_box.length; i++) { if (check_box[i].checked) { let deleted_tr = $(check_box[i]).closest('tr'); let deleted_tr_id = deleted_tr.data("id"); ids_to_delete.push(deleted_tr_id); } } $.ajax({ url: "/delete_cp_company", method: "POST", data: { cp_company_ids: JSON.stringify(ids_to_delete), csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(), }, enctype: "multipart/form-data", dataType: 'json', success: function (data) { processCompanyDelete(ids_to_delete, data.no_delete) }, error: function (xhr, status, error) { console.error('AJAX Error: ' + status + ' - ' + error); }, }); } I tried handling the IntegrityError in the try-except block, but the error still causes a 500 response.

Django Form using fields from multiple models

I suspect this is because the e4date field is not on the DPlaces model (it is on the DEntry model), but I am not sure. I any case, I am clueless on how to get this working. Any help is appreciated. -
How to manage multiple formset in Django with JavaScript
I have the following problem: I'm loading a form(Form A "Evento") for the User of application fill, in that Form I have to load dynamically another form(Form B "Logistica"), so that the User can add several Form B just clicking the button. I managed to load dynamically these Logistica/Form B for the User, but when I go to the saving part I only managed to receive the fields in a tuple, for example the Form B has a field called "nome", instead of receiving N FormB "nome" fields, I receive only 1 with a [] with the values of each Form. I realize that Django is thinking that instead of N FormB, I have only 1 FormB and it is concatenating the fields Problem https://github.com/ian-santos-nascimento/Django-event-management This is my form <form method="post" role="form" action="{% url 'evento_create' %}"> {% csrf_token %} <div class="form-group"> <label for="{{ form.nome.id_for_label }}">Nome</label> {{ form.nome }} </div> <div class="form-group"> <label for="{{ form.descricao.id_for_label }}">Descrição</label> {{ form.descricao }} </div> <div class="form-group"> <label for="{{ form.observacao.id_for_label }}">Observação</label> {{ form.observacao }} </div> <div class="row"> <div class="col"> <label for="{{ form.local.id_for_label }}">Local</label> {{ form.local }} </div> <div class="col"> <label for="{{ form.local.id_for_label }}">Cliente</label> {{ form.cliente }} </div> </div> <div class="form-group mt-3"> <label>Comidas</label> <div style="height: 30vh;overflow-y: scroll; … -
Simple JWT says sometimes "Token is invalid or expired" and sometimes gives correct output
I have a Django REST backend configured Simple-JWT solution. About 2/3 of the requests return # {"detail":"Given token not valid for any token type","code":"token_not_valid","messages":[{"token_class":"AccessToken","token_type":"access","message":"Token is invalid or expired"}]} and the rest returns the normal outcome. e.g. these curls I did directly one after another and the first fails while the second (same access token) returns a right value: C:\Users\user>curl -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNzE4NDAxMzc5LCJpYXQiOjE3MTg0MDA0NzksImp0aSI6Ijc2YTcwZjU0OTA2ZjQwOTNhYzc2MzRhYTFmNmJjNTlhIiwidXNlcl9pZCI6Miwicm9sZSI6MSwibGFuZ3VhZ2UiOm51bGwsImZ1bGxfYWNjZXNzX2dyb3VwIjp0cnVlfQ.p8BRy95SSiBmqeSjmCkAHFddRjKmzEOowP2RT34Jp6Y" http://3.71.19.16/accounts/courses/ {"detail":"Given token not valid for any token type","code":"token_not_valid","messages":[{"token_class":"AccessToken","token_type":"access","message":"Token is invalid or expired"}]} C:\Users\user>curl -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNzE4NDAxMzc5LCJpYXQiOjE3MTg0MDA0NzksImp0aSI6Ijc2YTcwZjU0OTA2ZjQwOTNhYzc2MzRhYTFmNmJjNTlhIiwidXNlcl9pZCI6Miwicm9sZSI6MSwibGFuZ3VhZ2UiOm51bGwsImZ1bGxfYWNjZXNzX2dyb3VwIjp0cnVlfQ.p8BRy95SSiBmqeSjmCkAHFddRjKmzEOowP2RT34Jp6Y" http://3.71.19.16/accounts/courses/ [{"id":1,"name":"Testkurs 1","language":1,"teacher":2,"grade":5,"start_date":null,"study_started":false,"activate_final_test":false,"number_of_students":90,"created_at":"2024-06-11T14:13:15.498484Z","scheduled_study_start":null,"scheduled_final_test":null,"demo":false},{"id":2,"name":"Testkurs 2","language":1,"teacher":2,"grade":5,"start_date":null,"study_started":false,"activate_final_test":false,"number_of_students":70,"created_at":"2024-06-11T14:17:58.503959Z","scheduled_study_start":null,"scheduled_final_test":null,"demo":false},{"id":3,"name":"Test","language":1,"teacher":2,"grade":5,"start_date":null,"study_started":false,"activate_final_test":false,"number_of_students":0,"created_at":"2024-06-13T22:35:51.513376Z","scheduled_study_start":null,"scheduled_final_test":null,"demo":false}] This is my Django Simple JWT-Setup: SIMPLE_JWT = { "ACCESS_TOKEN_LIFETIME": timedelta(minutes=15), "REFRESH_TOKEN_LIFETIME": timedelta(days=90), "ROTATE_REFRESH_TOKENS": True, "BLACKLIST_AFTER_ROTATION": True, "UPDATE_LAST_LOGIN": False, "ALGORITHM": "HS256", "VERIFYING_KEY": "", "AUDIENCE": None, "ISSUER": None, "JSON_ENCODER": None, "JWK_URL": None, "LEEWAY": 60, "AUTH_HEADER_TYPES": ("Bearer",), "AUTH_HEADER_NAME": "HTTP_AUTHORIZATION", "USER_ID_FIELD": "id", "USER_ID_CLAIM": "user_id", "USER_AUTHENTICATION_RULE": "rest_framework_simplejwt.authentication.default_user_authentication_rule", "AUTH_TOKEN_CLASSES": ("rest_framework_simplejwt.tokens.AccessToken",), "TOKEN_TYPE_CLAIM": "token_type", "TOKEN_USER_CLASS": "rest_framework_simplejwt.models.TokenUser", "JTI_CLAIM": "jti", "SLIDING_TOKEN_REFRESH_EXP_CLAIM": "refresh_exp", "SLIDING_TOKEN_LIFETIME": timedelta(minutes=15), "SLIDING_TOKEN_REFRESH_LIFETIME": timedelta(days=1), "TOKEN_OBTAIN_SERIALIZER": "rest_framework_simplejwt.serializers.TokenObtainPairSerializer", "TOKEN_REFRESH_SERIALIZER": "rest_framework_simplejwt.serializers.TokenRefreshSerializer", "TOKEN_VERIFY_SERIALIZER": "rest_framework_simplejwt.serializers.TokenVerifySerializer", "TOKEN_BLACKLIST_SERIALIZER": "rest_framework_simplejwt.serializers.TokenBlacklistSerializer", "SLIDING_TOKEN_OBTAIN_SERIALIZER": "rest_framework_simplejwt.serializers.TokenObtainSlidingSerializer", "SLIDING_TOKEN_REFRESH_SERIALIZER": "rest_framework_simplejwt.serializers.TokenRefreshSlidingSerializer", } and my nginx config server { listen 80; server_name 127.0.0.1; # change with url location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /home/ubuntu/USER/static/; } location / { # Add the necessary headers proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For … -
Django App Embedded in Shopify not setting CSRF token
We are facing a bit of an issue with CSRF tokens in our application. Our Django application is embedded in Shopify. I know browsers are getting a bit strict on the third-party cookies but haven't been able to find a solution to setting the CSRF token it the browser. For now, we are forced to comment out 'django.middleware.csrf.CsrfViewMiddleware', in settings.py, which I don't believe is the correct way to go. In my settings.py: CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = True ALLOWED_HOSTS = [ "admin.shopify.com", "www.mydomain.com", ] CSRF_TRUSTED_ORIGINS = [ "admin.shopify.com", "www.mydomain.com", ] ...

How to unify the result of three queries into one keeping the order given by order by in Django
I am trying to get a list from a model to show the results ordered by status, for example: first "active", then "in progress" and "not active" at the bottom of the list. At the same time the results for each status must be ordered by the date. I am using Django version 4.0 and MySQL database. I tried to implement this using Union, but the results are not being ordered correctly.

How to use Django generated fields to get a single value from a many-to-many relationship?
I have a Django model representing a Book, which can have many different types of Person, including AUTHOR, EDITOR, ILLUSTRATOR, etc. class PersonType(models.Model): name = models.CharField() class Person(models.Model): name = models.TextField() class Book(models.Model): title = models.TextField() people = models.ManyToManyField(Person, through="PersonBook") class PersonBook(models.Model): person_type = models.ForeignKey(PersonType, on_delete=models.CASCADE) person = models.ForeignKey(Person, on_delete=models.CASCADE) book = models.ForeignKey(Book, on_delete=models.CASCADE) I was hoping to use Django's new GeneratedFields to create a property on Book with the name author that could query the many to many relationship and set the value equal to the first Person with the "AUTHOR" PersonType. I'm certain there are other ways of doing this with Managers and what not, but I'm curious as to how I can do this with Django's new GeneratedFields, if that's even possible. The documentation on Django's Query expressions doesn't show any examples along relationships, so I'm not sure if it's possible to do anything there. -

How to Assign Existing Contacts to a Task Using Postman in Django Rest Framework Without Duplicating Email
I am currently working on a project using Django Rest Framework and Postman. My objective is to assign existing contacts to a task. However, when I make a POST request via Postman, I receive the error: "contact with this email already exists" The email field in my Contact model is defined as models.EmailField(unique=True), as I need to ensure that each email is unique across all contacts. When I attempt to assign an existing contact to a task using a POST request, I receive the aforementioned error. Here's the relevant part of my code: http://127.0.0.1:8000/tasks/ { "id": null, "title": "Postman", "description": "Postman", "dueTo": "2024-06-12T12:04:28Z", "created": "2024-06-12T12:04:31Z", "updated": "2024-06-12T12:04:34Z", "priority": "LOW", "category": "TECHNICAL_TASK", "status": "TO_DO", "subtasks": [ { "id": null, "description": "Postman", "is_done": false } ], "contacts": [ { "id": 1, "email": "max@mueller.com", "name": "Max Mueller", "phone_number": "123456789", "avatar_color": "#abcdef" } ] } models.py class Contact(models.Model): id = models.AutoField(primary_key=True) email = models.EmailField(unique=True) name = models.CharField(max_length=50) phone_number = models.CharField(max_length=30) avatar_color = models.CharField(max_length=7) def __str__(self): return f"{self.name}" serialzers.py class ContactSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Contact fields = ['id', 'email', 'name', 'phone_number', 'avatar_color'] models.py class Task(models.Model): id = models.AutoField(primary_key=True) title = models.TextField() description = models.TextField() dueTo = models.DateTimeField() created = models.DateTimeField() updated = models.DateTimeField() priority … -
My form is automatically being submitted in django whenever I open the link

Issue with Toggling between New Themes
I'm encountering an issue with a custom Theme Installation in my Django project using v. 4.2.13 and Python v. 3.9.7. In the default Admin side, there is a Moon icon for toggling the Themes (i.e. b/w Light and Dark and Auto). I want to add a Grey theme as my default with a new icon. So there are total 4 icons for themes now - Grey, Light , Dark & Auto. For implementing this, I added a new icon for the Grey theme and the icon is now not visible in the Admin panel (only the default 3 are shown) and the toggling between themes is not working. Below are the screenshots of the code for installing themes with their respective icons. Please also note my teammate has been working on Django 5.0 for making his previous project commits in Github. We wanted to test what can happen to the same functionality if team members work on different versions since we're assuming Git essentially stores all files as basic text files with version control. I am not sure if this has anything to do with my problem. Kindly help. Screenshot 1 - The Admin panel moon icon for theme toggle … -
Globally JSON-serializing UUIDs and other types with psycopg2 and django
I'm developing an application with Django 4.2.10. I am running a postgres database and use psycopg2. In my application, I am working with nested dictionaries (coming out of Django ninja/pydantic schemas) and I would like to write these to JSONField django fields. However, they contain UUID's which results in the following error: TypeError: Object of type UUID is not JSON serializable To resolve this problem, I really prefer a "global" hook/adapter that convinces psycopg2 to properly serialize UUID's and other types so that I don't have to worry about it in all the places where I write this data into the database. It should work for direct/raw queries but also via the Django ORM. I found this JSON Adaptation section in the psycopg2 docs. Note You can use register_adapter() to adapt any Python dictionary to JSON, either registering Json or any subclass or factory creating a compatible adapter: psycopg2.extensions.register_adapter(dict, psycopg2.extras.Json) This setting is global though, so it is not compatible with similar adapters such as the one registered by register_hstore(). Any other object supported by JSON can be registered the same way, but this will clobber the default adaptation rule, so be careful to unwanted side effects. So my thought … -
Session Timeout on User side in Django
I am trying add a session timeout in my Django project by using Django's in-built session middleware. I have implemented session timeout on my project using the Views method I have come across for this purpose and it is working on my Admin side, but in my User side, the redirection that I given not working (i.e. I need to log out the user and get back to the signin page after session expires). My django version : 5.0.2 My python version: 3.12.2 Now it is taking the time and that page will expire but it will not redirect to the signin page. How can I solve this issue? What are some other approaches we can use for implementing Sessions on Admin & User sides both redirecting to the Signup page and persisting the last page worked on upon logging back in ?settings.pymiddilewareViews.pyurls.py -
