SOS, huge doubt about ruby on rails

I have to do a web application where I have to use ruby on rails. I have
read some about it, but a partner told me something that I don't know if
it is true. He told that creating a table of a data base ruby on rails,
automatically creates two files html, one which shows the contents of
you table and the other one, provides a html file to introduce data in
your data base, is this true??

No, that's not true.

Your friend might have been thinking of the CRUD/scaffolding that Rails
lets you add *if you want* that will do the above, but by default it
doesn't happen unless you specifically tell it to.
