Hi all,

I have a problem that i want to print data in grid (table format)

following is my partial file named “\_coupon.haml.html”  
-coupon\_template.each do |template\_data|  
-coupon.initializeFromTemplate(template\_data)  
#div{:style=\>“border: solid; border-color: gray; width: 310px;”}  
=haml\_engine =  
Haml::Engine.new(CouponTemplate.find(coupon.template\_id).data).render(Object.new,  
:coupon =\> coupon)  
%input{:type=\>‘radio’, :name=\>‘coupon\_template\_id’, :value=\>  
template\_data.id}  
%br  
%br  
%br  
%br  
%hr  
%table{:width =\> “100%”}  
%tr  
%td{:align =\> “right”}  
=link\_to “Cancel”, polymorphic\_path(coupon.business)  
= submit\_tag ‘Next Step’

Currently i am printing coupons one after one.  
I want it like following

* * *

coupon 1 | coupon 2 | coupon 3 |  
| | |  
-------------------|------------------|------------------|  
coupon 4 | coupon 5 | coupon 6 |  
| | |  
-------------------|------------------|------------------|

I tried but there is no for loop such that

for i=0, i\<coupons.length, i+=3

Thanks,  
Vikas

Look at the AR docs for @collection.in\_groups\_of if you want to process  
the coupons in groups of 3.

@collection.in\_groups\_of is very helpful
