I am having difficulty passing datetime values to a method in the
controller. I get sql syntax error from the following. Can someone
advise me what I am doing wrong?

my view:

    <table>
      <tr>
        <%= start_form_tag :action => 'time_range' %>
        <td ><%=  datetime_select("sd", "time_range") %></td>
        <td ><%=  datetime_select("ed", "time_range") %></td>
        <td><%= submit_tag 'go'%></td>
      </tr>
    </table>

my method:

def time_range
  start_date=params[:sd]
  end_date=params[:ed]
  @orders=Order.find(:all,:conditions => ['created_at BETWEEN ? AND ?',
start_date, end_date])

end

hi,

you can do this,

 @start_date = Date.civil(params[:range]
[:"start_date(1i)"].to_i,params[:range]
[:"start_date(2i)"].to_i,params[:range][:"start_date(3i)"].to_i)
            @end_date = Date.civil(params[:range]
[:"end_date(1i)"].to_i,params[:range]
[:"end_date(2i)"].to_i,params[:range][:"end_date(3i)"].to_i)

thanks and regards,
shripad

Thanks Shripad
From your advice I've got the following. It worked fine until I added
hours and minutes to the range which are attributes 4i and 5i. I don't
get any error messages but don't get values from db either. Datetime
format in the db is 2003-10-14 12:37:51. Any suggestions would be
appreciated.

my view:

    <table>
      <tr>
        <%= start_form_tag :action => 'time_range' %>
        <td ><%=  datetime_select("sd", "range") %></td>
        <td ><%=  datetime_select("ed", "range") %></td>
        <td><%= submit_tag 'go'%></td>
      </tr>
    </table>

my method:

def time_range
  @start_date = DateTime.civil(params[:sd][:"range(1i)"].to_i,
params[:sd][:"range(2i)"].to_i,
params[:sd][:"range(3i)"].to_i,params[:sd][:"range(4i)"].to_i,
params[:sd][:"range(5i)"].to_i)

  @end_date =
DateTime.civil(params[:ed][:"range(1i)"].to_i,params[:ed][:"range(2i)"].to_i,params[:ed][:"range(3i)"].to_i,params[:ed][:"range(4i)"].to_i,
params[:ed][:"range(5i)"].to_i)

  @orders=Order.find(:all,:conditions => ['created_at BETWEEN ? AND ?',
@start_date, @end_date])

end

Thanks for reply Shripad;

Db is Mysql. Following is the sql running for the last query:
 'select paydate,payamount,credit,paymenttype,memberid from payments
where paydate between '2008-10-09T14:22:00+00:00' AND
'2008-10-10T14:22:00+00:00'

Format in db is 2003-10-14 12:37:51

Greetings Everyone..

In the conditions of your query you should pass the parameters as simple
strings.
User strftime to get the desired string representation while passing it
to
the query
I'd try this:

@orders=Order.find(:all,:conditions => ['created_at BETWEEN "?" AND
"?"',
start_date.strftime('%Y-%m-%d %H:%M:%S'), end_date.strftime('%Y-%m-%d
%H:%M:%S')])

the format above is the one u mentioned as the default of your database
engine "Format in db is 2003-10-14 12:37:51"

Looks like you're using rails 1.1 or earlier. In more recent versions
of rails you don't need to do any of this:

Order.find(:all,:conditions => ['created_at BETWEEN ?
AND ?',start_date, end_date])
would just work

start_date.to_s(:db) might work, but I really can't remember what
works on really old versions of rails.

Thanks for the tip Fred.

I hadn't tried Order.find(:all,:conditions => ['created_at BETWEEN ?
AND ?',start_date, end_date]) myself... it does work on rails 2.1.0

I've setteled for the following and works great!

@orders=Order.find(:all,:conditions => ['created_at BETWEEN "?" AND
"?"',
start_date.strftime('%Y-%m-%d %H:%M:%S'), end_date.strftime('%Y-%m-%d
%H:%M:%S')])

I am using 1.8 but somehow just start_date and end_date without
formatting did not work.

BIG THANKS TO YOU ALL
Katsuo

That's ruby 1.8. Rails version are independant of that
