It shouldn’t impact cause you can set that field to be (blank=True,
null=True) in this case it won’t raise an error and you can attach the
imported data to the related account manager.

We receive the data every two weeks and then use django-import-export to import

Hi,
As suggested using Postgres as a database backend would give you first

data.
See

If you switched to Postgres you could use a json data type or dictionary

Hi Mark,
I have some questions to you.
1. Does any of MetaData have predefined list of MetaDataValues?
2. Can MetaDataValue be assigned to many Documents or it is specific to
particular Document?

Okay, I explored model generation a bit and found an approach that wasn't
too offensive. For those that are trying to solve the same problem that I
am, here is what I came up with:

Thanks for the reply Bill. The problem I had with that approach is that
after creating the product I have to worry about creating red and green
ports. Likewise, upon deletion, I have to mop up the ports. Looking
through the documentation, I did not find a way to bury this behavior in the
Model.
I'm not clear on what you need to store, so I'll assume that you have individual
data to store for each port of each type, and it is unrelated to data stored for
another instance of the same or a different product.
What comes to mind is that there is a "Product" model and a "Port" model (or if

The true relational way would be to have another Model called
JobRunParameter with an FK on Parameter. It's getting a bit silly though and
all these look-ups are going to be a pain later on.
If Parameter is just a string key/value style thing, I might have simplified
things a little and instead of
