Postgres array support for Active Record
Add basic support for postgres arrays to activerecord, with special attention to getting rails migrations / schema dumps working nicely.
gem install activerecord-postgres-arrayor if you use bundler
gem 'activerecord-postgres-array'create_table :people do |t|
...
t.string_array :real_energy
t.decimal_array :real_energy, :precision => 18, :scale => 6
...
end
Note
As of activerecord-postgres-hstore ‘0.7.0’, ActiveRecord::Base#arel_attributes_value is not monkey patched and therefore does not interfere with loading of this gem.
If you are using ‘0.6.0’, or earlier, of activerecord-postgres-hstore you must use this gem’s version ‘0.0.8’ and the following still applies:
activerecord-postgres-hstore and activerecord-postgres-array both monkeypatch ActiveRecord::Base#arel_attributes_values, which leads to problems if these gems are used together. This gem is aware of activerecord-postgres-hstore and incorporates it in the monkeypatch. However, it is important that activerecord-postgres-array is loaded after activerecord-postgres-hstore for this to work.
