Originally assigned to: @jeremystretch on GitHub.

Environment

  • Python version: 3.6.9
  • NetBox version: 2.7.5

Steps to Reproduce

  1. Start with a v2.7.4 installation
  2. Create a site named "1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a"
  3. Upgrade to v2.7.5 and run apply database schema migrations

Expected Behavior

All migrations should complete successfully.

Observed Behavior

The migration 0095_primary_model_ordering fails with the following error:

django.db.utils.DataError: value too long for type character varying(100)

This happens because the name "1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a" expands to a string greater than 100 characters in length, which is the maximum length for the database field. The naturalization function accepts an argument to cut the naturalized string to a specific length, however the parameter is not being passed by the migration function.

It should be noted that this can be reproduced with any model using naturalized ordering if the source name is constructed in such a way that its naturalized version exceeds 100 characters.
