It is in the docs, the :student says that the object being displayed
and submitted is of type student, the @student is the variable
containing the student. In fact since these are the same word you do
not need both, either :student or @student will work I think, though
using @student is more usual I think. Having both allows the class
name and variable to be different.

I don't know why you have the html options they should not be needed.

I also don't understand why this is going to the beiratkozas
controller, I would have expected it to go to the students controller.
I would have expected you to put :url => { :controller =>
'beiratkozas', :action => "create" } to send it to that controller.
Check the html of the page (View, Page Source or similar in browser).

By the way it may be a good idea to put your comments inline with the
previous posts as it is then easier to follow the thread.
