I''m having trouble workign out which ActionView DateHelpers to display
a
time input for an ActiveRecord field of type :time.
I just want an hours input and a minuites input. I can get these with
time_select helper using :field_name and :prefix but it gives both hours
and miniutes the same name.
<%= select_time(Time.now, :prefix => "search", :field_name =>
"start_time") %>
<select name="search[start_time]">
<!-- hour options -->
<select name="search[start_time]">
<!-- min options -->
I see when you use the datetime_select it gives each element something
like 1i, 2i, 3i and 4i, this does not happen with select_time.
The datetime_select would work if I could get rid of the date part,
there is no time_select helper! And I have tried adding the :discard
option but it does not get rid of the year...
<%= datetime_select("search", "start_time", {
:discard_year => true,
:discard_month => true, :discard_day => true }) %>
Can anyone clue me in :)
Kris.

I just had to deal with this a few days ago, and this is what I came up with. You are almost there... drop the :field_name option as that won''t help you (it changes [hour] and [minute] to [start_time]). Keep the :prefix option, and set it to the name of the attribute of your model object. <%= select_time(Time.now, :prefix => "start_time") %> Then, when you get to your action, you have to take the params for the time selection and massage them into params for the model. For a Foo model, do this: params[:foo][:start_time] = Time.parse(params[:start_time][:hour] + ":" + params[:start_time][:minute]) Then you can do the usual foo = Foo.new(params[:foo]) and you''ll get the start_time as part of the bargain. If you figure out a better way to handle this, please let me know. My approach works fine, but it''s not very pretty. It looks like there is a patch in the works to add a time_select helper that is model aware, but it hasn''t had much love lately so it might be a while before it''s ready for use. --josh http://blog.hasmanythrough.com -- Posted via http://www.ruby-forum.com/.
Excellent, I actually tried something similar but could''nt get it to work, I like Time.parse, I was not aware of it :) Many thanks. It suprised me there was not a data aware Time select helper actually. I dont know if you noticed this but when you store a time and then print it to screen you also get a date? @search.start_time.class # => Time <%= @search.start_time %> # => Wed Mar 22 11:06:00 GMT Standard Time 2006 Josh Susser wrote:> > <%= select_time(Time.now, :prefix => "start_time") %> > > Then, when you get to your action, you have to take the params for the > time selection and massage them into params for the model.

The patch was already submitted and I believe it is fixed in Rails trunk. -- Posted via http://www.ruby-forum.com/.
Thanks Maxim, Im on Rails 1.0.0 at the moment, may give the trunk a go Which would be better than my method of getting putting the correct values back in to the Time inputs on a failed save. I store the time values in the session before trying to save the record. So if it fails the edit view can get the time values entered already from the session.

In my case I am doing a date_select for the rest of it (I can''t use datetime_select because the :order option does not work for it) This will only take the minutes, so I really had to do it twice, once with select_minutes and once with select_hours like this: <%= date_select ''event'', ''event_at'', :order => [:month, :day, :year] %> Time <%= select_hour(Time.now, :prefix => "event", :field_name => ''event_at(4i)'', :ampm => true) %> <%= select_minute(Time.now, :prefix => "event", :field_name => ''event_at(5i)'', :minute_step => 15) %> -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
