Nayati is a Rails engine that helps in creating a clean and maintainable multi tenant Rails application. Creating multitenant application with Nayati allows you to have models that do just database talking and business logic gets handled by a layer I like to call 'Operation layer'. The sequence in which these operations get executed for a tenant is put in database.

= sql_valued_columns SqlValuedColumns is an ActiveRecord plugin that will let you have specific SQL statements executed on INSERT / UPDATE. It will call the SQL function you provide, passing the arguments specified in the call to sql_column. See the documentation for SqlValuedColumns::ClassMethods#sql_column for more information regarding usage, including passing Strings and Proc objects as arguments to your SQL function. Example: You have a model with two columns, one named "another_column" and the other named "size_of_another_column". Whenever you insert data into "another_column", you want to have size_of_another_column have the result of the SQL function LENGTH inserted into it. class MyModel < ActiveRecord::Base sql_column :size_of_another_column, "LENGTH", :another_column end Example 2: You have a model with three columns, position, latitude and longitude. Latitude and longitude are values expressed as angles, and position is a special datatype for your database that represents the X/Y/Z projection of that particular latitude and longitude (example: http://www.postgresql.org/docs/8.3/static/earthdistance.html ) When you insert data with latitude and longitude, you want to automatically call a function in your database to transform the latitude and longitude into the appropriate represenation. class MyModel < ActiveRecord::Base sql_column :position, "ll_to_earth", :latitude, :longitude end Example 3: You are an insane criminal who has somehow learned SQL. You would like to make anyone who runs your code to suffer database punishing queries and odd security and data formatting issues that will make them rue the day they ever learned of computers. class MyModel < ActiveRecord::Base sql_column :a_column, "(SELECT count(id) FROM large_list_of_things)", :raw => true sql_column :another_column, '(SELECT count(other_id) FROM other_large_list_of_things WHERE some_column = \'#{some_model_method}\')', :raw => true end == Notes No tests yet, am lazy. == Copyright Copyright (c) 2009 Chris Zelenak.
