Rails engine to generate instant reports from adhoc SQL query.

• Export ad-hoc SQL reports in some formats:
  • .csv
  • .json
  • .xlsx
• Persist generated report as local file or in AWS S3
• Rails 4.x
• Nice administration console with rails engine

• Label data substitution

Add this line to your application's Gemfile:

gem 'adhoq'

And then execute:

$ bundle

Or install it yourself as:

$ gem install adhoq

Install migrations

$ bundle exec rake adhoq:install:migrations
$ bundle exec rake db:migrate

Mount it in config/routes.rb

Rails.application.routes.draw do
  root  to: 'hi#show'

  mount Adhoq::Engine => "/adhoq"
end

Edit initialization file in config/initializers/adhoq.rb

Adhoq.configure do |config|
  # if not set, use :on_the_fly.(default)
  config.storage       = [:local_file, Rails.root + './path/to/store/report/files']
  config.authorization = ->(controller) { controller.signed_in? }
end

See configuration example in dummy app.

Then restart server and try it out.

Adhoq also provides report generation from SQL string, not from mounted rails engine.

execution = Adhoq::AdhocExecution.new(
  'xlsx',
  'SELECT "hello" AS name ,"English greeting message" AS description'
)

Adhoq::Reporter.generate(execution) #=> report data

Persistence is also available without engine via Adhoq::Storage::SomeClass#store. Below is example that generating report and persist to in Rails application report method.

execution = Adhoq::AdhocExecution.new(
  'xlsx',
  'SELECT "hello" AS name ,"English greeting message" AS description'
)

storage   = Storage::S3.new(
  'my-adhoq-bucket',
  aws_access_key_id: 'key_id',
  aws_secret_access_key: 'access_key'
)

# generate report and store it to S3, returns `key` to get report data
key = storage.store('.xlsx') { Adhoq::Reporter.generate(execution) }

...
storage.get(key) #=> report data
