Noob simple question create custom options_for_select

Hello everyone,

I’m starting learning ruby on rails and i have a question that maybe is
more
about ruby but anyway.

I have a table with 2 columns type and value and i would like to create
a
select that had like options all the values but for certain types they
should appear as the text.
I want to achieve something like:

Select the option:

private public Group tkk Group Rails Group The great school User testi1 User testi2 User testi3

In my example i would like that all the lines that is related to users
or
groups has the type in the select text.

Can i use select or should be select_tag and also how can i create this
default options if they come from the database and i have to do some
“coding” before put into the select?

Any tips will be appreciated.

Thank you!

Before you go any further I suggest that you read
http://en.wikipedia.org/wiki/Entity-attribute-value_model,
particularly the caveats listed at the bottom of the article. Except
in extraordinary circumstances adopting an eav model defeats the
purpose of a relational database system from the outset.
