select_tag and :include_blank => true not working
Guys,
I''m using select_tag to display a non-model dropdown, which works fine.
However, I''ve tried every which way to use the :include_blank => true
option, but it simply won''t display a blank value. Using :include_blank
=> true with select on model fields works fine.
Can someone please show me a working example?

Select Box problem in the controler with Ajax
Hi,
I have a selectbox that updates a given span area when a user selects a
value. The selectbox has the option :include_blank => true. The
controler will fetch the ID of the selected option in the combo box and
sends the description of the item with the same ID.
The problem is that the user is able to select the empty option, and the
controler will not be able to fecth the ID. This

Authentication: UserEngine or own creation?
Hi all
I''m coding a project that needs a lot of authentication stuff... e.g. I
write sort of a profile area, where users can create their different
profiles.
So I need to check if a user has the right to browse the profiles, if he
has the right to change them all (as an admin) or the ones that belong
to him etc. etc. This needs quite some logic...
Now I wonder whether to use the

Safe way to destroy records
Hello,
how can I check if a destroy was successful?
Is the object only frozen if deleted or do I have to do an additional
find to see if there is a record left?
What happens if an after_destroy callback returns false? Is there always
a rollback?

date_select and :include_blank
Hi,
date_select is a great helper, but I couldn''t find a way to make it display
a text like "Please Select" instead of blank field.
When I use date_select with a param of :include_blank => true, it renders an
option with a value of "" and string of "". I want to display "Please
Select". Anyway to do this? Maybe overwriting ActionView modules

Active Record: Can it auto-create database tables for you?
Hi,
Just get started with Rails and I''m trying to read ahead and find out
whether Active Record supports auto-creation of database tables for you?
Is this supported, or is the concept that you write your own database
DDL to do this?
Thanks

disabled for quite sometime now. I''ve already emailed the administrator

any idea on when this would be enabled ?
