hi everyone, I hope someone can help me out with some active record
basics? I''ve been banging my head for the past 4 hours and I can''t seem

Field names in validators
Hi!
Is there a (simple) way to use alternative field names in validation
messages? For example, if I have a validator like this one:
validates_presence_of :email
how can I make it print a message like "E-Mail Address can''t be blank"
instead of "Email can''t be blank"? I can override the "can''t be blank"
part by using the :message

ActiveRecord: Getting table names
How do i get (discover) all the table names within a database using
ROR/ActiveRecord ?
I wish to build a webapp that connects to a database on the fly,
discovers tables and column names etc and then can show data or build a
report based on user selection. The ActiveRecord API doesnt seem to give
any method for getting table names.

Passing a value from one rhtml to another
I''m trying to find a way to get from one rhtml page to another and
taking a value along to use in the second page. Basically a user clicks
on one of many download links and what should appear on the next page is
all the available stuff related to that download, so I think if I take
the id number of the first page then i can use if statements in the
second page? Sorry if that sounds

Paginating a .find
how exactly would I apply paginate to a .find I have:
@posts = Post.find(:all,
:conditions => [ ''(title) OR (body) LIKE ?'', ''%''
+ params[:query] + ''%''],
:order => ''end_date'')
How would I go about paginating the uoputed list? Something like 10 on a
page.
