For my first rails app, I’m building a web page that will list some  
restaurants and then have the user rate them from from 1 to 5 using 5  
radio buttons. The view code looks like:

### Ratings:
 \<% for rating\_option in [1,2,3,4,5] -%\> \<% end -%\> \<% for user\_rating in @ratings -%\> \<% for rating\_option in [1,2,3,4,5] -%\> \<% end -%\> \<% end -%\> 

| Restaurant | \<%=h rating\_option.to\_s -%\> |
| --- | --- |
| \<%=h user\_rating.restaurant.name -%\>: | \<%= radio\_button(:user\_rating, :rating, rating\_option) -%\> |

Where @ratings contains an array of objects from find(:all), and I want  
to assign the value of the radio button to user\_rating.rating (an int  
field in the table).

This code links all the radio buttons for all rows in one group. How  
can I assign a group of radio buttons to a specific row? Also, where is  
the documentation on the options hash for radio\_button?

Thanks,
