Hello,

i have the application set up on my radrails. I was looking at the view  
generated by scaffold and i see a bunch of names, after looking up  
internet i found that they are helpers and generate the HTML for us.

Now, i wanted to look at the helper code for start\_form\_tag, so that  
based on that i could write some of my own helpers in my helper  
classes… but i could not find the code anywhere for

start\_form\_tag, end\_form\_tag, or submit\_tag or render or anything… !!

Also where could i find out what are the parameters required for these  
helpers (if i cant see the code ) ??

Thanks for any help,  
Satya.

First of all, all the methods listed in the API have their  
corresponding code.  
[http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000403](http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000403)  
and click on “Show Source” to check it out.

Unfortunately I don’t know the path where gems are installed on  
RadRails, but in your Ruby dir, the helpers are in  
gems/1.8/gems/actionpack-1.11.2/lib/action\_view/helpers.

RadRails doesn’t come with Ruby or rails or any of that… it just uses  
the install you  
have on your system.
