Changing Year, Month, or Day in a Django model's date field using annotate
I have a Django model MyModel class MyModel(models.Model): """My Model that stores date.""" date = models.DateField() In my API I am receiving a param, review_month I need to get all the entries in MyModel and replace their date's year value. I have the following condition for what year to add: -> If date__month is greater than review_month the year will be current year otherwise the year will be previous year. I need these new date fields with updated years for every entry of the MyModel queryset MyModel.objects.annotate( updated_year=Case( When( Q(review_date__month__gt=review_month.month), then=previous_year), default=current_year, output_field=IntegerField(), ), ) ) This only give me year separately but I want an updated_date that has day and month of date field and this new updated year in it and must be a DateField as I need to apply sorting to it. -

Compare Python Dictionary values with Django Database fields
I'm looking for a way to compare a python dictionary values with Django ORM entries. I have a dictionary contains product information like following: product_1 = { "ProductId": "552049", "BarCode": "552049", "Height": 200, "WholesalePrice": 10.65, "RetailPrice": 18.78, "Length": 62, "LongDescription": "Spray 400ml", "ShortDescription": "Spray 400ml", "Volume": 818, "Weight": 354, "Width": 66, } These values stored on a Django database. The number of products are very big, about 200.000 products and after a few days I need to compare and update the products if something change. I know that a way is to iterate to products and compare values but I'm looking for a better approach to compare products more faster. I'm thinking about to create a checksum and stored as a field in database and later when I update the products, first compare the checksum and if is different then update the database field. But I don't know if this the best way. Can someone suggest me a fast way for this? -
