[web2py] Re: Newbie Tables Question

[黄祥]

i think it can be achieve in the view part by jquery.

e.g. i assume you use sqlform.grid with the table food and have the table 
field food_type (requires=IS_IN_SET('Pizza', 'Steak')) and field 
specific_food
*default/food.html*
{{extend 'layout.html'}}

{{=grid}}

<script>
jQuery(document).ready(function(){
    if(jQuery('#food_food_type').val() == 'Pizza'){
        jQuery('#food_specific_food__row').show();
        jQuery('#food_food_type').change(function(){
            if(jQuery('#food_food_type').val() == 'Pizza')
                jQuery('#food_specific_food__row').show();
            else 
                jQuery('#food_specific_food__row').hide();});}
    else {
        jQuery('#food_specific_food__row').hide();
        jQuery('#food_food_type').change(function(){
            if(jQuery('#food_food_type').val() == 'Pizza')
                jQuery('#food_specific_food__row').show();
            else 
                jQuery('#food_specific_food__row').hide();});}
});
</script>

hope this can help
best regards
