# This cop enforces the absence of explicit table name assignment.
#
# `self.table_name=` should only be used for very good reasons,
# such as not having control over the database, or working
# on a legacy project.
#
# If you need to change how your model's name is translated to
# a table name, you may want to look at Inflections:
# https://api.rubyonrails.org/classes/ActiveSupport/Inflector/Inflections.html
#
# If you wish to add a prefix in front of your model, or wish to change
# the default prefix, `self.table_name_prefix` might better suit your needs:
# https://api.rubyonrails.org/classes/ActiveRecord/ModelSchema.html#method-c-table_name_prefix-3D
#
# STI base classes named `Base` are ignored by this cop.
# For more information: https://api.rubyonrails.org/classes/ActiveRecord/Inheritance.html
#
# @example
# # bad
# self.table_name = 'some_table_name'
# self.table_name = :some_other_name
