Django: Saving database with manipulated .csv file | Error: “” value has an invalid date format
I have csv file and It is updating by another platform periodically. I am trying to import this csv file to my database.

Django Maximum Recursion Depth Exceeded. View loops infinitely
I am writing an application that will decode make, model, and year information for provided VIN numbers from cars.

Issue joining data in graphene-django with a ManyToMany field
I've been trying to find a good example for returning a query set with joined data across a ManyToMany field, but I've not found one. Given the following model: class Task(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) detail = models.ManyToManyField("Detail", through="TaskDetails") class Detail(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) detail_name = models.CharField(max_length=250) class TaskDetails(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) task = models.ForeignKey("Task", related_name="detail_tasks") detail = models.ForeignKey("Detail", related_name="task_details") detail_value = models.CharField(max_length=250) I'd like to return the data for Task with it's related details. Based on the answer on this question, I tweaked my schema to the following: class TaskDetailsType(DjangoObjectType): class Meta: model = TaskDetails fields = ("id", "detail_name", "detail_value") detail_name = graphene.String() def resolve_detail_name(value_obj, info): return value_obj.detail.detail_name class TaskType(DjangoObjectType): class Meta: model = Task fields = ("id", "task_details") task_details = graphene.List(TaskDetailsType) def resolve_task_details(value_obj, info): return value_obj.detail_tasks When I run this though, I get an error: {'errors': [{'message': 'User Error: expected iterable, but did not find one for field TaskType.taskDetails.'}, {'message': 'User Error: expected iterable, but did not find one for field TaskType.taskDetails.'}, {'message': 'User Error: expected iterable, but did not find one for field TaskType.taskDetails.'}], 'data': {'getInboxTasks': [{'id': 'a430e49d-c9c3-4839-8f2c-aaebbfe9ef3a', 'taskDetails': None}, {'id': '74c8dacc-1bfd-437a-ae34-7e111075ac5e', 'taskDetails': None}, {'id': '10956caa-d74f-4a01-a5cf-9cac6a15c5a3', 'taskDetails': None}]}} -

Django object search
I am trying to make a search bar for some QuerySet objects. How can I make this code cleaner? filtered = test.filter( Q(user__icontains=query) | Q(notes__icontains=query) | Q(fees__icontains=query) | Q(date__icontains=query) ) This code looks through all the fields of the model for the search query. I am thinking a way to make this cleaner is somehow pass in a list like ['user', 'notes', 'fees', 'date'] and then running __icontains for all the items in the list. -

Run django and postgresql on two computers
We are developping a website with two developpers. The first one is a superuser but not the second one. We don't have a server but only a mutualized server. The issue is that when we need to do python manage.py migrate (or makemigrations), we have to log in the website of the server provider and to open the security consol (which is only open for ten minutes), which takes 2/3 minutes each time. When i was working alone, it was faster to have a local database on my computer and to do a quick manage.py migrate in conda. Is it possible to use my personnal conda window to do a manage.py makemigrations on a distant mutualized database ? If not what would be the best solution to share the database ? Thanks a lot -
