I have a form with a datetime
field. Since Rails 3.2.13 doesn't support type="datetime-local"
input
fields yet (and I'm not ready to move to 4.0 beta), I'm doing this manually:
<input type="datetime-local" name="person[my_date_time]"<% if @person.my_date_time %> value="<%=@person.my_date_time.strftime('%FT%T')%>"<% end %>/>
The problem is @person.my_date_time will be the current date/time if it's nil
in the database. And it outputs with seconds too which screws up Chrome's handling of datetimes. I want that field to be empty if it's nil
in the database. How can I tell? Rails' datetime_select
method handles it the way I want.
If the datetime field is nil
in the database something in your application must be changing or overwriting that value. Perhaps you have a default somewhere? It's not really possible to say what is going on without seeing more code than what is posted now. Can you post the code for you Person
model and any other relevant code (any gems which might affect things, etc.)?
strftime("%FT%R") # Will output without seconds, e.g. "2013-04-18T21:43"
