Rails - Apr 2005 - noob question: rhtml new/edit views and the date functionality

Hello All,

I''ve been playing with Rails - did the recipe/category sample from
onLamp.com - fairly straight forward - even got it working against
postgres.

Anyway, I''ve been appling rails to a small test project and I
can''t
seem to get the syntax down or find a sample of how to use the date
control on a custom new/edit view.  The CRUD (is that right?) that
automatically detected the date field & generated the date dropdowns
when I didn''t specify any custom method overrides or custom views -
that was handy, but now I''m trying to generate a custom form to add
some style.

If anyone could please help me get the syntax down for the simple
recipe.date example to generate the date select boxes, I would be very
appreciative - I can then apply it to my test project.

Basically, the "Recipe" table looks like this:
id   int8
title  varchar(255)
description    text
date   timestamp
category_id   int8 (fk to the category table)

and I need to generate the select boxes for the date column.  I''ve
been browsing the API and the datetime_select/select_datetime and can
get the unbound stuff to show with this chunk of code:

<% =select_datetime(datetime = Time.now, options={}) %>

but I want it tied automagically to my database field.  I know it is
something simple that i''ve overlooked and can''t seem to grasp
while
browsing the API.  i''ve tried this which does not work:

<% = datetime_select(@recipe.date, "recipe[date]", options={}%>

The CRUD generates HTML like this:
year: <select name="recipe[date(1i)]">
month: <select name="recipe[date(2i)]">
...
seconds: <select name="recipe[date(6i)]">

which is essentially what I want.

Thank you,

Clay

Clay, 

If you haven''t already seen it, I think the Rails 4 Days tutorial has
examples pretty close to what it is you''re wanting to do:

Form helpers generally take their parameters as (object, method,  
{hash_of_other_options} ). There is exceptions, of course, so consult  
the api docs (http://rails.rubyonrails.com) for the exact syntax.  
datetime_select is no exception, so you should call it like this:

<%= datetime_select("recipe", "date") %>

If you don''t have any options, don''t specify them. ={} in the
function
definition means that an empty hash is the default options parameter  
unless something else has been given. API docs have often examples  
(like in this case  
http://rails.rubyonrails.com/classes/ActionView/Helpers/ 
DateHelper.html#M000382) which you can draw advantage from if you''re  
not quite sure how you should use the function.

No, scaffold doesn''t generate that, it generates a datetime_select call
(see the rhtml file for the action in question). When that function is  
called, it expands to the html input fields you describe above.
