Ruby On Rails, dynamic table’s & add button using nested_attributes

So here’s the problem, you want to create several items that belong to one item, normally you would just the the has_many and belongs_to (OneToMany) relation in rails. Using this model you create the primary model (such as purchase order) then create several sub items (such as item) and attach them to the primary model. The problem with this is its time consuming and does not always make sense to do things this way, take the Purchase order and Items scenario, it makes much more sense to create the Purchase order and assciated Items in the same form.

How To Install Ruby on Rails Ubuntu Server 11.10

Ruby Rails is a Web application framework created in 2004 intended as a rapid development web framework. It was intended to emphasize Convention over Configuration (CoC) meaning the developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table “products sold”, that the developer needs to write code regarding these names. It has also been designed around the “Don’t repeat yourself” principle. Both of these ways of thinking allow you, with Ruby Rails, to create excellent, dynamic websites very quickly.
