Module: PGTrunk::Migration

Defined in:
lib/pg_trunk/core/railtie/migration.rb

Overview

The module goes around the ActiveRecord::Migration's method_missing.

This is necessary because +ActiveRecord::Migration#method_missing+ forces the first argument to be a proper table name.

In Rails migrations the first argument specifies the +table+, while the +name+ of the object can be specified by option:

pg_trunk_create_index :users, %w[id name], name: 'users_idx'

in PGTrunk the positional argument is always specify the name of the the current object (type, function, table etc.):

pg_trunk_create_index 'users_ids', table: 'users', columns: %w[id name] create_enum 'currency', values: %w[USD EUR BTC]

With this fix we can also use the options-only syntax like:

pg_trunk_create_enum name: 'currency', values: %w[USD EUR BTC]

or even skip any name when it can be generated from options:

pg_trunk_create_index do |i| i.table 'users' i.column 'id' end
