Unable to insert objects under a has_many through: "table_name" association

[jwaldrip]

Given the following model, my after :save hook is not allowing me to add associated objects that have a has_many through relationship. It fails on compile with the error:

In lib/clear/src/clear/sql/insert_query.cr:147:13

The issue seemed to be with UUID foreign keys. I was able to resolve it by going back to auto-incrementing keys. So there is a bug here, but I am not blocked for the time being.
