What I'm trying to do:
Display a form in a table using Rails, using a more compact method
than simply spitting out the HTML for the entire form. So if I've got
a model called Client, which has a field called "active", and I want a
checkbox displayed with the label "Active?", the scaffolding code
gives me something like this (apologies if this renders oddly):
<tr>
<td><label for="client_is_human">Human?</label></td>
<td><%= check_box 'client', 'is_human', {}, 'yes', 'no' %></td>
</tr>
This has a bit of duplication, and I'd like to be able to boil it down
to something like this:
<%
def wrap_form_helper(label, formHelperSymbol, object, method,
*otherArgs)
# do magic
end
%>
<%= wrap_form_helper 'Human?', :check_box, 'client', 'is_human', {},
'yes', 'no' -%>
How I've tried to do this:
def wrap_form_helper(label, formHelperSymbol, object, method,
*otherArgs)
formHelper = method(formHelperSymbol)
control = formHelper.call(object, method, otherArgs)
# wrap control in some table tags and return it
end
The above Method#call code works fine as long as I only pass the first
four arguments. Any more than that and I get a message to the effect
that Array#stringify_keys is undefined.
I can, of course, do a big case statement on the arity of otherArgs
and pass otherArgs[0], otherArgs[1], etc... but that's horribly wrong.
(It's still better than building a string for eval(), though,
considering that one of the arguments is a hash.)
Can't really STFW for this because I'm not sure what I'm looking for.
Is there some way to expand an array and send its elements to call()?
Any help appreciated,
-Sam
