In at least two places I want to display radio buttons for choosing a
persons gender. Now, with radiation levels rising and everything, I
want to be safely guarded for future changes to basic biology, such as
a third sex. And, anyway, I try to heed the admonition not to repeat
myself.
A concrete fragment from an existing view looks like this
<fieldset>
<legend>Gender</legend>
<label for="gender_female">Female</label>
<%= radio_button "person", "gender", "F",
"id" => "gender_female" %>
<label for="gender_male">Male</label>
<%= radio_button "person", "gender", "M",
"id" => "gender_male" %>
</fieldset>
What I don''t understand, yet, is how to parameterize and where to put
the fragment so that I can call it the same way as other helpers, i.e.
as gender_choice("person", "gender").
Maybe implementing a "component" like this as a method isn''t
even
advisable and there are better ways.

That''s it with a slight syntactic change render_partial ''shared/gender'', nil, :person => person, :gender => gender From the wiki I found this page http://www.pointstorm.com/~gavin/partials-doc/classes/ActionView/Partials.html which was helpful for the details.

Just got up this morning, and on my mind was the content of a changeset to Rails that I saw yesterday that plays with how the assignments are made in partials; the line that you''ve posted should do the trick.

That documentation you found will be modified to match the changes and included in the source. Under the new code, you can do: render_partial ''shared/gender'', :person => person, :gender => gender i.e. no need for that nasty ''nil''; and you can use symbols for the local variable names. Gavin
