Hi,

Having big problems with radio buttons that just don’t make sense:

\<%= radio\_button “events”, “impact\_type”, true %\> Positive  
\<%= radio\_button “events”, “impact\_type”, false %\> Negative

This should create two radio buttons with the first one checked by  
default, right? Cos it doesn’t ☹

Any ideas would be great,  
Thanks,  
Bex

try 1 and 0 instead of true and false

calling the boolean field directly gives you a 1 or 0. You only get the  
true/false if you call the method with a ?

So the form helper tries to match the values of the option buttons to  
@events.impact\_type, which gives a 1 or 0.

Hi Becky,

Try this instead:

\<%= radio\_button “events”, “impact\_type”, true, :checked =\> true %\>

The API for  
radio\_button[http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#M000395](http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#M000395)indicates  
the 3rd param as the value  
of the radio button, not whether the checked attribute it set or not.

But I guess you might have mistaken it with the API for  
radio\_button\_tag[http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M000501](http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M000501)  
.

Hi,

Try using

\<%= radio\_button “events”, “impact\_type”, “true”, {:checked =\>  
‘checked’} %\>
