Textfield Length Django

Question

I am trying to get a len of a textfield in Django so I can manipulate it in my template since the name of the school is too long, it is overlapping in the PDF display. I found this old post here in SO How to get the length of a TextField in Django?

I am trying to get the length of a school field which is related to another model.

x = Recipient.objects.get(id='1234551') len(x.department.school)

This gives me an error: object of type 'Recipient' has no len(). School is also a field and it seems to work on the old post. I just don't understand why it doesn't work in my end.

Sorry, forgot to mention that Department is a foreignkey of Recipient and School is Foreignkey of Department. — tango ward

What kind of field is x.department.school ? Is that the CharField or the ForeignKey?

Or maybe it has to be something like len(x.department.school.name) ?

You will have to post your models for us to give a complete answer.

school is a foreignkey. You're correct Sir, I should've put it the x.department.school.name. May I know if len() works in FK too?

To my knowledge, len() does NOT work on ForeignKey fields, since those are usually integers in the database
