Module: ActiveRecord::ConnectionAdapters::ColumnDumper

Defined in:
lib/activerecord/monkey_patch/rails5_1.rb

Overview

This is a monkey patch to the problem below. As a result of ‘rails db:schema:dump`, the `DATE` type column expects to return `t.datetime :created_at`. But actually `t.date :created_at` is returned.

Perhaps, converting the ‘DATE` type created in Rails 4 to `TIMESTAMP(6)` type that is used in Rails 5 makes this monkey patch unnecessary.

Original code is the following URL.

github.com/rails/rails/blob/v5.1.0.beta1/activerecord/lib/active_record/connection_adapters/abstract/schema_dumper.rb#L9-L11
