Overview

Detects ‘class Foo < Sequel::Model(:table)` which introspects the database schema at require time and will crash if the DB is unavailable. Use a lazy `define_model` pattern instead.

Examples:

# bad
class Task < Sequel::Model(:tasks)
end

# good
def self.define_task_model(db)
  Class.new(Sequel::Model(db[:tasks]))
end
