Django DRF: "Positional argument follows keyword argument unpacking" when trying to add current user
I'm trying to add the currently logged in user into the "user" foreign key field in the "LeadFacilityAssign" model, everytime a leadfacility object gets created. But I'm getting this: "Positional argument follows keyword argument unpacking" models.py class Lead(models.Model): first_name = models.CharField(max_length=40, null=True, blank=True) last_name = models.CharField(max_length=40, null=True, blank=True) agent = models.ForeignKey("User", null=True, blank=True, on_delete=models.SET_NULL) def __str__(self): return f"{self.first_name} {self.last_name}" class LeadFacilityAssign(models.Model): assigned_facilities = models.ForeignKey(Facility, on_delete=models.CASCADE, related_name='leadfacility', null=True, blank=True) lead = models.ForeignKey(Lead, on_delete=models.CASCADE, related_name='leadfacility', null=True, blank=True) datetime = models.DateTimeField(null=True, blank=True) user = models.ForeignKey('User', on_delete=models.CASCADE, null=True, blank=True, related_name='owner') serializers.py class AssignedFacilitySerializer(serializers.ModelSerializer): class Meta: model = LeadFacilityAssign fields = ('assigned_facilities', 'datetime', 'user') class LeadUpdateAssignedSerializer(serializers.ModelSerializer): is_owner = serializers.SerializerMethodField() assigned_facilities = AssignedFacilitySerializer(required=False, many=True, allow_null=True) class Meta: model = Lead fields = ( "id", "agent", "is_owner", "assigned_facilities", ) read_only_fields = ("id", "agent", "is_owner") def get_is_owner(self, obj): user = self.context["request"].user return obj.agent == user def update(self, instance, validated_data): assigned_facilities = validated_data.pop("assigned_facilities", []) user = self.context["request"].user instance = instance for item in assigned_facilities: instance.leadfacility.create(**item, user) return instance -
I need to make regular working Queue when its not empty in Django
PROJECT: I am making a web app, where users send a ZIP file, it saves to the folder. There is a VM continuously looking for that folder where the zip gets extracted. Note that VM is only 1. So I have to extract, sleep for 20 seconds and remove the files from that folder, VM generates the results, then my Django app generates a CSV from those files, and return to user as downloadable. This is the flow. Problem: MultiUsers: I am using a file, like below def Uplaoder(request): file=takenFromPost() #lets assume this works. with open('busy.txt', 'r') as f: if "false" in f: with open('busy.csv', 'w') as f: f.write('true') #here I made it true so that if its true, the request doesn't disturb it as single VM f.close() finalcsv=workFurther() #here is the whole process lets say. with open('busy.csv', 'w') as f: f.write('false') f.close() return render(request, 'worked.html', {'finalcsv':finalcsv}) elif "true" in f: Uploader(request) #here I send this request again to this so that the user keeps waiting and when the #files gets generated for the second user, he gets the response. Here is the example logic, same as my code works. Problem: Logic seemed me well but the browser doesn't wait … -
User accessible in views but not in template
I am trying to use {% if user.is_authenticated %} in a template, but the user actually doesn't exist. If I try to output {{ user }}, there is nothing. In my settings I have those options for TEMPLATES: "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", I developed an authentication backend class to use the credentials of the active directory and added the class to AUTHENTICATION_BACKENDS in settings.py. class CustomAuthenticationBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): """ Authenticate user from active directory If user is not found, create it """ # Get user from database try: user = User.objects.get(username=username) # If user does not exist, create it except User.DoesNotExist: user = User(username=username) user.displayed_name = kwargs['display_name'] user.email = kwargs['email'] user.save() return user def get_user(self, user_id): try: return User.objects.get(pk=user_id) except User.DoesNotExist: return None I added the authenticate logic and the login logic to a django Form: def authenticate_and_login(self, request) -> bool: """ Method to authenticate the user and login return True if user is authenticated and logged in or False and fill the form with errors """ is_logged = False # Init active directory service ad_service = ActiveDirectoryService() # Get username and password username = self.cleaned_data['username'] password = self.cleaned_data['password'] # Get authorized user from … -
How to store mathematical symbols and formulas in column sqlalchemy Postgres as DB
I have two questions: What I want to do is to be able to store a mathematical question with special symbols, formulas that are part of the text. What column should I define in SQLAlchemy so that I can get back the equation without any issue. Second part involves in data entry, I want to upload questions in bulk, now the special symbols cannot be defined/written as text in excel, I was able to do it in MSWord. Is there any specific rules that I can define so I can read the equation in that rule and transform it into mathematical equation. For Ex. similar to latex, if we type [\sqrt{x^2+1}], we see the math format in pdf. That way I can provide a input text where they can write equations in that format and it automatically converts it into math formulae and display it as such. Now is there any intelligent way to achieve this? I'm using Fastapi with SQLAlchemy and for database, I'm using Postgres. If you could point me to relevant resources, that would have great help. -
Django with mysql, faced 'table doesn't exist' error randomly at different times of the day
I'm currently using Django version 2.2.28 with mysql innodb engine version 5.7, before some days i faced a crazy issue, here: (MySQLdb._exceptions.ProgrammingError) (1146, "Table 'db_name.table_name' doesn't exist") What's driving me crazy is that they happen on different tables at different times (not always). I couldn't even get a specific pattern. i can confirm no change in the code happened from along o week and no release happened, The problem started happening 3 days ago and randomly, same table is currently working fine and a minute later the same exception is returned and then back to working fine. i used RDS from AWS, and have different DBs under of it, the issue happening only on one of these DBs. i also checked logs file from mysql and i don't fond any thing useful, i just found errors like this [ERROR] InnoDB: MySQL is freeing a thd though trx->n_mysql_tables_in_use is 2 and trx->mysql_n_tables_locked is 654 and i think it's irrelevant. I make sure about all permissions for the user too. and i did a failover for the whole RDS and nothing working. I don't think it has to do with django's migration command, because this problem always happened randomly. can any one … -

How to use a custom ModelForm in User admin
I'm trying to limit standard user possibilities in the User application Django's admin, to avoid the possibility of privileges escalation.

Time gap between message.errors in django

Adding multiple authentication classes in API using Django Rest Framework
I have multiple internal services communicating with a django server using DRF, I have implemented token authentication on django server to authenticate requests coming from different services. I want to develop an API which can be accessed by more than 1 external service. So in my API I declared authentication_classes = [ServiceAuthClass1, ServiceAuthClass2] and permission_classes=[] Following what DRF documentation says for custom authentication the overridden authenticate method in ServiceAuthClass1 and ServiceAuthClass2 should return None if you dont want to attempt authentication using that authentication class and you want DRF to check with another authentication class(ref). Agreed and Done! In case authentication does not happen with any mentioned class DRF is not raising any error/exception. How am I suppose to handle this case? -
