Travis CI，Rails和Postgresql-错误类型hstore不存在

Question

I'm getting:

PG::UndefinedObject: ERROR:  type "hstore" does not exist
LINE 1: ...arying(255), "finish" timestamp, "widget_locations" hstore) 

Below is my Travis config file:

language: ruby
rvm:
  - 2.0.0
env:
  - DB=postgresql
script: 
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare
  - bundle exec rspec spec/
before_script:
  - cp config/database.travis.yml config/database.yml
  - psql -c 'create database virtual_test' -U postgres
  - psql virtual_test -c 'CREATE EXTENSION hstore' -U postgres
bundler_args: --binstubs=./bundler_stubs
before_install:
  - bundle update debugger-ruby_core_source

I also have below migrations file:

class SetupHstore < ActiveRecord::Migration
  def self.up
    execute 'CREATE EXTENSION IF NOT EXISTS hstore'
  end
  def self.down
    execute 'DROP EXTENSION IF EXISTS hstore'
  end
end

This however creates the error regardless.

Is there something wrong here?

Answer 1

Might be too late with this but encountered the same problem. Changed hstore create to this:

 - psql virtual_test -c 'CREATE EXTENSION IF NOT EXISTS hstore' -U postgres

And rake db:test:prepare to this:

 - RAILS_ENV=test bundle exec rake db:test:prepare

Its weird but it worked, might help you out as well.

Answer 2

This is probably caused by a search_path issue as described in this answer:

Answer 3

Change your before_script to this:

before_script:
  - psql template1 -c 'create extension hstore;'
  - cp config/database.travis.yml config/database.yml
  - psql -c 'create database virtual_test' -U postgres

Note that we're creating an extension on the first line.
