Hi all, I am new to this place and ruby on rails as well.

I am developing a web application where I have to create a form which  
displays the checkboxes. The names of these checkboxes have to be  
fetched from a database. Can some one help me out of this ?

</div>

\<%= check\_box :modelname, :attribute, options, on\_value, off\_value %\>

Example:

check\_box “post”, “validated” # post.validated? returns 1 or 0

check\_box “puppy”, “gooddog”, {}, “yes”, “no”

Just use it…  
If you can’t understand, get back again

currently i am using this in my view, which makes it pretty hard  
coded…can u suggest something else in place of it(which dynamically  
fetches the checkbox names from a database)

Also, I want to use two databases(one for fetching the checkbox names,  
and the other is for my application). Do I need to include some extra  
code for it?

The doc for ActiveRecord::Base has a section titled  
“Connection to multiple databases in different models”

Perhaps that would be a good place to start 🙂
