Hey guys,

How can we give two form\_for based on conditions? I mean like this:-

unless condition1.nil?  
form\_for :abc, :url =\> { :action =\> “123” } do |f|  
else  
form\_for :abc, :url =\> { :action =\> “234” } do |f|  
end

This is not working. Can you guyz tell me where is the problem ? How can  
i write this scenario.

The problem is that form\_for takes a block. You can’t write only half a  
block before else.

Also, unless…else doesn’t make sense. Use if…else.

In the controller:

@action = condition1.nil? ? ‘234’ : ‘123’

And in the view:

form\_for :abc, :url =\> {:action =\> @action} do |f|

Best,
