When using radio_button, how do you get some text in the label? For
instance, the API ref gives the following example:
radio_button("post", "category", "rails")
<input type="radio" id="post_category"
name="post[category] value="rails" checked="checked"
/>
My own use of radio_button is not showing any label. This might be
because the data is numeric, not a string. Anyway, continuing the
above example, how would I get the following output?
<input type="radio" id="post_category"
name="post[category] value="rails"
checked="checked">
The Rails Category -- YEAH!
</input>
The problem I have is trying to map text strings for importance
("High", "Medium", "Low") to integers (3, 2, 1).
Any clues?

This example is from my comic book application. class CreatorJob @@values = { 1=>''writer'', 2=>''penciller'', 3=>''inker'', 4=>''colorist'', 5=>''letterer''} def self.values @@values end end # creates attributes with the numbers as values CreatorJob.values.each do |k,v| CreatorJob.module_eval %Q{def self.#{v}\n #{k}\n end} end Now, I use this like so: @model.job = CreatorJob.writer # sets it to 1 Here''s an example: http://dev.comiclog.com/file/trunk/lib/creator_job.rb If there''s a better way, I''m all ears. -- rick http://techno-weenie.net

I want a (different) label for _each_ radio button.>> The problem I have is trying to map text strings for importance >> ("High", "Medium", "Low") to integers (3, 2, 1).So for this mapping, I want the following abbreviated HTML (I think). <label for="importance">Importance</label> <input type="radio" id="post_category" name="post[category] value="1">high</input> <input type="radio" id="post_category" name="post[category] value="2">medium</input> <input type="radio" id="post_category" name="post[category] value="3">low</input> At the moment, I _am_ using the <label> tag, but the radio buttons appear by themselves. They _are_ responsive, in that I can use them to affect the model, but a user would have no idea which one to select.> This probably isn''t the Rails Way (tm), but I took a cue from my c# > experience and its enums.

Makes sense, I guess. Now I''m using the radio_button method successfully, so I''m happy. Gavin
