Hello,

I have the following code in the little application that I am writing.  
It is  
basically taken directly out of the Agile Web D. with Rails  
book.

In the controller:

```
@exercises = Exercise.find(:all).map { |f| [f.name, f.id] }

```

And in the view

\<% form\_tag :action =\> ‘create’ do %\>  
…  
Exercise: \<%= select\_tag(:id,  
@exercises)  
%\>  
\<% end %\>

## And this is what it is producing: Exercise: Incline Dumbbell Press1Push-up2Squats3Incline Dumbbell Press4Push-up5Squats6asdfasdf7another test8asdfasdfasdfasdfasdf12349asdfasdfasdfasdfasdf123410111test exercise

no description12testing error stuffs13

This is obviously not what I was expecting. It makes it really hard to  
pick  
something from what I thought would be a nice little drop down select  
widget.

What am I doing wrong?

## Thanks, Chris

select\_tag creates the tag, but you need to add in the  
options you want…do something like this:

[http://api.rubyonrails.com/classes/ActionView/Helpers/FormOptionsHelper.html#M000511](http://api.rubyonrails.com/classes/ActionView/Helpers/FormOptionsHelper.html#M000511)

select\_tag(“id”, options\_from\_collection\_for\_select(@excersises,  
“title”, “id”))

hth 🙂
