This rubocop will match all change_column/add_column/create_table/alter_table statements
|
|
and check if there are :datetime or :timestamps column which do not have the limit: 3 setting.

|
|
good:
|
|
|
|
change_column :smime_certificates, :not_after_at, :datetime, limit: 3
|
|
|
|
create_table :sessions do |t|
|
|
t.timestamps limit: 3, null: false
|
|
end
|
|
|
|
bad:
|
|
|
|
change_column :smime_certificates, :not_after_at, :datetime, limit: 4
|
|
|
|
create_table :sessions do |t|
|

t.timestamps null: false
