Hello everyone,
I’m having issues with a “time” field in a model. On the view, I use a
time_select helper to generate the select for this field, and since I
need this field to be NULL sometimes, I include the
option :include_blank => true, like this:
<%= time_select ‘support’, ‘duration’, :minute_step =>
15, :include_blank => true %>
The problem is that when I use :include_blank, the generated select
comes with the hidden fields (of year, month and day) empty, like
this:
00
01
02
03
...
21
22
23
:
00
15
30
45
And so, when I submit the form with the time field filled, I get an
ActiveRecord::MultiparameterAssignmentErrors. If I don’t set the
option :include_blank => true, the hidden fields for year, month and
day come filled with the respective current values, which are ignored
by MySQL since we’re storing them in a time field, not a datetime, and
the insert or update goes on fine.
Is this a Rails bug (i’m using version 1.2.2) or am I doing something
wrong here?
Thanks,
Rodrigo.
I just had the same issue (wasted hours trying to work it out, it
shouldnt be this painfull)
What i have ended up doing (it is a bit horrible but it works)
<%= select_time @event.start_time, {:prefix =>
‘start_time’, :time_separator => ’ : ', :include_blank => true} %>
Then in the update action before the update_attributes call
if params[:start_time] && ! params[:start_time][:hour].blank? && !
params[:start_time][:minute].blank?
params[:event][:start_time] = “#{params[:start_time]
[:hour]}:#{params[:start_time][:minute]}:00”
else
params[:event][:start_time] = nil
end
I would really like to hear about a cleaner way to do this

AaronT,
With this solution, does the time_select field still automatically
gets the model field value in edit forms? Or do you need some hacking
in the edit action too?
Rodrigo.
Yes it automatically fills in the value if not null
luckly no extra hacking was needed
