ScenicOracleEnhancedAdapter

This gem provides an adapter for the Scenic gem for use with the Oracle Enhanced Adapter.

Installation

Add this line to your application's Gemfile:

gem 'scenic_oracle_enhanced_adapter'

And then execute:

$ bundle

Then add a Scenic initializer (or modify your existing initializer) to make Scenic use this adapter:

# config/initializers/scenic.rb

Scenic.configure do |config|
  config.database = Scenic::Adapters::OracleEnhanced.new
end

Switching from rails_sql_views to Scenic

In Oracle 12, replacing a view has issues when the view refers to objects outside its own schema; use update_view, which will drop and create. The replace_view method can still be used for views referring to objects in their own schema.

1. Run bundle exec rails g scenic:view <full_view_name> (if you use a prefix for the view, include it).
2. Move the view's SQL definition from the original migration into the newly-created file in db/views.
3. In the original migration, delete any drop_view call.
4. Copy the create_view or update_view line from the scenic migration and substitute it for the old create_view method and block.
5. Delete the scenic migration file
6. For the down method, copy the update_view line into the down (replacing any drop_ and create_view methods) and make the version: argument to the same number as the revert_to_version: argument (e.g. update_view :complex_data_view, version: 2, revert_to_version: 1 becomes update_view :complex_data_view, version: 1, revert_to_version: 1)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
