Just to rephrase it, since Web Application such as shopping cart has
many dependencies, Ruby is not ready for such application. Unlike PHP,
Ruby lack many dependencies to build a descent web/graphical
application. Is correct statement?
No.
A web shopping cart is an application that depends on many things:
the backend (database, flatfiles, ...) the output format (XML,
HTML, Wiki, ...) and the messages it's supposed to respond to (i.e.
the method calls and return values). It's extremely hard to write
a generic shopping cart unless the user of the cart is willing to
take whatever dependencies the cart has (e.g. different database,
certain method calls to use it etc.)
If one knows the parameters, writing a shopping cart is simple in Ruby. The dependencies are those of the *application*, not the
language.
