Hi everyone,
 
I am having a hard time changing the properties of an ZClass instance.
 
This is what I have done so far:
 
I created a producted called MTB_HQ. Within that product I created the ZClass "racedate". The ZClass has the a propertysheet called "date_properties".
The sheet contains the properties "date_day","date_month","date_year","date_sort","title","discipline","location". All string type.
 
2nd I edited the "racedate_add" method as described in the "Searcheable Job Board"-How-To (unique timestamp ids, etc).
 
Then I made a html form in:
 
|
|--mtb_hq
        |
        |
      admin
 
 
The form calls the method "addracedate.dtml" in /mt_hq/admin/racedates. Here's the code:
 
****************************
"addracedate.dtml"
---------------------------
 
<dtml-call "REQUEST.set ('date_sort', year_html+month_html+day_html)">
<dtml-call "REQUEST.set ('title', location_html+' '+day_html+'.'+month_html+'.'+year_html)">
<dtml-call "REQUEST.set ('date_day', day_html)">
<dtml-call "REQUEST.set ('date_month', month_html)">
<dtml-call "REQUEST.set ('date_year', year_html)">
<dtml-call "REQUEST.set ('location', location_html)">
<dtml-call "REQUEST.set ('discipline', discipline_html)">
 
<dtml-with "manage_addProduct['MTB_HQ']">
  <dtml-call "racedate_add(_.None, _, NoRedir=1)">
</dtml-with>
 
<dtml-call "RESPONSE.redirect ('../index.htm')">
 
******************************
 
 
 
Ok, so now I have the instance with the new properties and I can display it and everything - fine!
 
But what do I do now when I want to change the properties of an existing ZClass instance through a web form?
I tried back and forth wit manage_changeProperties but I jsut can't get it to work. Believe me I searched through all the How-Tos and documentation available but couldn't find any hint that got me further.
 
My idea is to create a web form that is filled with the properties of existing ZClass. The you can make changes and the form calls a method that does the changing of the properties. But how do I do that?
 
My web form (very basic now, not formatted in any way) right now looks like this:
 
***************
"editracedates_form.htm"
---------------------------------------
<dtml-with racedates>
<dtml-in "Catalog(id=obj_id)">
<form method="post" action="racedates/changeRaceDate.dtml">
  <p>
    Day     <input type="text" name="day_html" value ="<dtml-var date_day>">
    Month  <input type="text" name="month_html" value ="<dtml-var date_month>">
    Year    <input type="text" name="year_html" value = "<dtml-var date_year>">
    </p>
  <p>
    <input type="text" name="location_html" value ="<dtml-var location>">
    location&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <input type="text" name="discipline_html" value ="discipline">
    discipline </p>
   
  <p>
    <input type="submit" name="Button" value="Abschicken">
  </p>
  </form>
  </dtml-in>
 </dtml-with>
****************
 
 
How should the dtml-method "changeracedate.dtml" look like? Or could one of you guys point my nose at the right doc or how-to?
I have really been playing around with this quite a while and just can't figure out how to use mange_changeProperties right!
 
Many, many thanks in advance and sorry for this quite lenghty posting.
