module PGTrunk::Migration
@private 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
