AttributeError: 'Division' object has no attribute 'replace'

• Does export still work for other works?
  • No
• Why does this work on the read work page?
• Is the template engine supposed to stringify everything for me?
• Are others seeing the same issue?
  • https://stackoverflow.com/questions/24322614/django-custom-template-tags-str-object-has-no-attribute-notification-set
    • This doesn't seem the same
• What part of the template is failing?
  • <h2>{{chapter|replace:"βοοκ,Book"|capfirst}}</h2>
  • Changing the order makes this work. It appears that the template engine does not force the incoming data into a string. This actually makes sense.

• Calling str on the object doesn't fix it
• I'm guessing the str function is returning the actual division somehow
• Removing the str function from the Division model doesn't fix it

• Division model is not returning a str from str
  • Removing str changed the behavior
• Which part of the str branch has the issue?
  • None are having issues now
  • However, the division titles are wrong
• I'm using the template engine wrong
