I am starting my first ruby rails project and I am impressed with it. I am learning the basics of ruby and I can see why people enjoy it as a language. Now, here is what I want to know:

Should I really bone up on ruby for a good few days (For instance, this weekend) and learn all I can about:

Strings, vars, arrays, loops, etc

or is Rails, the framework, so focused on using its own syntax/logic, that it's really not necessary? I just worry that if I learn ruby I might find that "rails wants to run with ruby but the syntax/logic is different with this framework". Will I be able to steam roll through rails development if I learn to 'master ruby' or is it going to be necessary to change a bit of what I learn if I want to use ruby language with the rails framework?
