So the api listing says that radio\_button(object, method, tag\_value,  
options = {}) gives a radio button tag, and if object.method ==  
tag\_value, then the button will be checked.

I verified the method behaves correctly for attributes of type string.  
However, if the attribute is of type int, it doesn’t make the button  
checked.

Does anyone have some information before I file a bug?  
Some tricks to make it work?

Ezra,  
I ran into the same problem. But i think i’ve found a solution:

## I have the following table:

Table: accounts  
id :integer  
…  
…  
foo :integer (this is the field with value for the radio  
button)

* * *

edit.rhtml

Here i have the following options, for the user to select:

\<%= radio\_button(“account”,“foo”, “1”) %\>  
\<%= radio\_button(“account”,“foo”, “2”) %\>

* * *

show.rhtml

My show view, shows the data for account with the instance  
variable @account, but to make my Radio-buttons work properly  
(I want the correct radio button to be selected) I had to do  
the following:

\<%= radio\_button(“account”,“foo”,“1”, :disabled =\> true) %\>  
\<%= radio\_button(“account”,“foo”,“2”, :disabled =\> true) %\>

After that the show.rhtml showed the Radio Buttons and the  
the correct Radio Button will be selected, based on the value  
in in the table accounts and attribute foo.

Plus,

don’t use TINYINT(1) as Datatype in MySQL.  
Rails will return the values as True of False.

Aha! Thanks for comfirming that! I had a lot of trouble figuring that  
one out when I was working through the otherwise-excellent “4 days with  
rails” tutorial!  
Cheers
