Hi all,

I have problem about HAML rendring

I have following small test for haml rendering

> > a = Coupon.first

if i give following to console

> > haml\_engine = Haml::Engine.new("%h3 Avatar =image\_tag( Photo.find(t.busines  
> > s.avatar\_id).public\_filename(:thumb), :width =\>‘80px’, :height =\>

IT GIVES ----\>

=\> “

### Avatar =image\_tag( Photo.find(t.business.avatar\_id).public\_filename(:th umb), :width =\>‘80px’, :height =\> ‘80px’)
\n”
* * *

BUT IF I GIVE

> > haml\_engine = Haml::Engine.new("=image\_tag( Photo.find(t.business.avatar\_id).  
> > public\_filename(:thumb), :width =\>‘80px’, :height =\>  
> > ‘80px’)").render(Object.new  
> > , :t =\> a)

I got following error

NoMethodError: undefined method `image_tag' for #<Object:0x6ab04a4> from (haml):1:in`render’  
from  
c:/ruby/lib/ruby/gems/1.8/gems/haml-2.2.1/lib/haml/engine.rb:167:in  
`render' from c:/ruby/lib/ruby/gems/1.8/gems/haml-2.2.1/lib/haml/engine.rb:167:in`instance\_eval’  
from  
c:/ruby/lib/ruby/gems/1.8/gems/haml-2.2.1/lib/haml/engine.rb:167:in  
`render’  
from (irb):8  
from :0

Why the image\_tag is not executing here?  
How to solve this problem? Please give me solution.

Thanks,  
Vikas

I can’t tell from the formatting whether your haml is correct, but the  
reason you aren’t finding image\_tag from the console is probably that  
you don’t have the ActionView helpers included. Look up image\_tag and  
then include the fully-qualified module for image\_tag and try again.  
You might also try posting to the Haml Google Group  
([http://groups.google.com/group/haml](http://groups.google.com/group/haml)  
).

Hope this helps.
