SequelAsteriskHunter

This extension hooks into Sequel::Dataset#fetch_rows method, doing some predefined action when an SELECT * statement is found.

Add this line to your application's Gemfile:

gem 'sequel-asterisk-hunter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sequel-asterisk-hunter

The extension needs to be initialized by the Sequel extension interface. The simplest way to configure it globally is by adding this line to the initializer:

Sequel.extension :asterisk_hunter

or

Sequel::Database.extension :asterisk_hunter

However, if you are using any framework (like Rails) where your Sequel::Database instance already exists, you should use DB.extension :asterisk_hunter, where DB is a reference to your Sequel::Database, like this:

Sequel::Model.db.extension :asterisk_hunter

You could define an action to be executed when any SELECT * statement is found. It must be any callable object.

With the default action:

DB[:my_table].all
  #=> "Find 'SELECT *' in query!"
  #=> [<All your objects and its attributes/columns>]

With some custom actions defined:

• Raising an error:

action = -> { raise StandardError, "Find 'SELECT *' in query!" }
Sequel::Extensions::AsteriskHunter.define_action(action)

DB[:my_table].all
  #=> StandardError("Find 'SELECT *' in query!")
  # (Your query is not executed...)

• Logging:

action = -> { Rails.logger.warn("Find 'SELECT *' in query!") }
Sequel::Extensions::AsteriskHunter.define_action(action)

DB[:my_table].all
  #=> "Find 'SELECT *' in query!"
  #=> [<All your objects and its attributes/columns>]
