I have a problem with the datetime\_select helper.  
In my view i use these both statements:

\<%= datetime\_select :absent :last\_date %\>  
\<%= date\_select :absent :last\_date %\>

in my db last\_date is declared as type ‘datetime’

The date\_select helper works fine, but the datetime\_select helper  
generates a

private method ‘hour’ called for #\<Date: 49…\> message

in date\_helper.rb :150 in ‘select\_hour’

Thanks for help

What are you unhappy about; why can’t you use the version that works?  
What are you trying to do?

You mean you think that datetime\_select doesn’t do what it was designed  
to do?

Why does the error message say \<#Date… if you say the column is  
datetime ?

What do you get when you execute, in “script/console”,

ModelName.columns.find { |a| a.name==‘last\_date’ }

(I don’t know the model name in question here)

The date\_select only shows the date. The datetime\_select normaly gives  
you date and time - and thats what i need. I tested both, because both  
use the same parameter - so i think there is a error in rails.

Many thanks for your direction. It was not rails, it was was my fault. I  
used the wrong column in my db.
