Radio_button_tag and default checked option

Rails
1

Hi, I can’t get my radio button to be checked by default, here is what I
have:

<%= f.radio_button :gender, “male”, :checked => ‘true’ %>

Male


<%= f.radio_button :gender, “female” %>

Female

Here is the generated html:

Rails is going nuts here, why is Rails generating the id
“user_gender_male”??? That’s why everything is going wrong.

I think, the way you are using the :checked option may be wrong.

Try with,

:checked => true
:checked => ‘checked’

Returns a radio button tag for accessing a specified attribute
(identified by method) on an object assigned to the template (identified
by object). If the current value of method is tag_value the radio button
will be checked. Additional options on the input tag can be passed as a
hash with options.
Examples

Let’s say that @post.category returns “rails”:

radio_button(“post”, “category”, “rails”)

=> <input type=“radio” id=“post_category” name=“post[category]”

value=“rails” checked=“checked” />

or just do :checked => ‘checked’ yourself in the options.
