Any links or pointers where I can learn about various data types available in ruby(on rails) ?

Question

Some datatypes which I commonly use are string ,integer while creating models *text_field, text_area and password_field* while creating forms inside views.

Data types to use with models are my first priority .

There's a few good sites for this. I recommend this as a reference :

The only major pitfall I ever landed in with datatypes with the different between bignum and int . Other than it's all very straightforward.
