Why does Django store charfield as a tuple?
Say I have a simple model in django class Customer(models.Model): session_id = models.CharField(max_length=200) nuts3 = models.CharField(max_length=200) To save a model object I will do this Customer.create(session_id = "unique_session_id", nuts3 = "some text") Now say that I need to overwrite the nuts3 in the saved model object with some other text customer = Customer.objects.filter(session_id = "unique_session_id") customer = customer[0] customer.nuts3 = "some new text" customer.save() When viewing the saved customer object in admin, I see a tuple in the nuts3 charfield ('some new text',). I have expected in the field only to have the string without a tuple. How come that Django added the string as a tuple? -

Optimizing Database Population with Django
I have a 10GB csv file (34 million rows) with data(without column description/header) that needs to be populated in a Postgres database. The row data has columns that need to go in different Models. I have the following DB schema: Currently what I do is: Loop through rows: Create instance B with specific columns from row and append to an array_b Create instance C with specific columns from row and append to an array_c Create instance A with specific columns from row and relation to B and C, and append to an array_a Bulk create in order: B, C and A This works perfectly fine, however, it takes 4 hours to populate the DB. I wanted to optimize the population and came across the psql COPY FROM command. So I thought I would be able to do something like: Create instance A with specific columns from the file for foreign key to C create instance C with specific columns from the row for foreign key to B create instance B with specific columns from the row Go to 1. After a short research on how to do that, I found out that it does not allow table manipulations while copying … -
How to not change value if an input is empty

The problem is when I click on it and then click away it shows an empty value. I need to somehow check that and make it not change the value if the input is empty. How can I do that? -
