Description
Rails: 4.1
DB: PostgreSQL 9.3
Adapter: Activerecord PostGis Adapter 2.2.1 https://github.com/rgeo/activerecord-postgis-adapter
In my database.yml I use this here (required adapter for PostGis):
development:
adapter: postgis
...
My migration:
...
def self.up
change_table :users do |t|
t.string :email, index: { case_sensitive: false, unique: true }
...
Any idea how to solve this problem?
