I have a Ruby project with a User object that consists of various  
fields (attributes). Two of these are preferredStart and preferredEnd  
and were configured with the “… script/generate scaffold …”  
command to have type “time”. When I visit the resulting “New User”  
page, the input for those two fields has date and time. In other  
words, the user could select a month, date and year in addition to  
hour, minute and second for preferredStart and preferredEnd. The  
relevent code from the view/new\_user.html.erb is:

\<%= f.label :preferredStart %\>  
 \<%= f.datetime\_select :preferredStart %\>

\<%= f.label :preferredEnd %\>  
 \<%= f.datetime\_select :preferredEnd %\>

Is there a way to limit the input selection to simply hour and  
minute? I tried, for instance:

\<%= f.datetime\_select :preferredStart, prompt =\> {:hour =\>  
true, :minute =\> true} %\>

That did not have the intended effect, though.

Have a look at time\_select.

By the way, you should ask Rails questions here:

Had I included content that was not ‘legal’? Apologies to all if I  
had.

That did it, thank you for the quick reply and the nudge in the right  
direction. As you probably have guessed, I’m way down on the left side  
of the learning curve. Thanks!
