Rails - Aug 2005 - Re: Newbie question: mysterious i afer using formhelper

Thank you very much for quick response. I gocha check my spelling more carefully
next time ;) (I just wish the mispell like this could show up when I use check
syntax command...)
Now I finished the list action and things work well.  On the other hand I notice
one thing I ''m not sure if it is a problem or not:  when user press new
and action create is started(based on the scaffold template)  I used some form
helper,, and the code is
 
<%= error_messages_for ''work_time'' %>
<!--[form:work_time]-->
<p><label for="work_time_check_in">Check
in</label><br/>
<%=datetime_select(''work_time'',
''check_in'')%></p>
<p><label for="work_time_check_out">Check
out</label><br/>
<%=datetime_select(''work_time'',
''check_out'')%></p>
<!--[eoform:work_time]-->

when I look at browser and views the source code. it''s like the one
below. Could someone tell me where is that (1i), (2i)...come from?does that
'' i'' matter?
 
 

<!--[form:work_time]-->
<p><label for="work_time_check_in">Check
in</label><br/>
<select name="work_time[check_in(1i)]">
<option value="2000">2000</option>
<option value="2001">2001</option>
<option value="2002">2002</option>
<option value="2003">2003</option>
<option value="2004">2004</option>
<option value="2005"
selected="selected">2005</option>
<option value="2006">2006</option>
<option value="2007">2007</option>
<option value="2008">2008</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
</select>
<select name="work_time[check_in(2i)]">
<option value="1">January</option>
<option value="2">February</option>
<option value="3">March</option>
...
Thank you.

The 1i, 2i, 3i etc that you see are indexes created by the
datetime_select method so that each component of the submitted date
can be seperated and parsed appropriately. It''s simply a rails format
so that dates can be handled more conveniently, definitely nothing to
worry about.

The indexes break down like this:

1i = Index #1 = Year
2i = Index #2 = Month
3i = Index #3 = Day of the month
4i = Index #4 = Hour
5i = Index #5 = Minute
6i = Index #6 = Second

So if you wanted to grab only the year from a date submitted by a
datetime_select you could do:

year = @params[''object''][''date(1i)'']

Of course, it''s often easier to rely on the magick of ActiveRecord to
automatically parse a date object from each indexed value as would
happen if you wrote:

object.attributes = @params[''object'']
