How to write a hash for a nested form??

Example form fields (main model is Practice, nested is User):  
practice[name]  
practice[users\_attributes][0][email]

I want to do this:

post:  
post :create, :practice =\> { :name =\> “any name”, :users\_attributes =\>  
{  
:0 =\> { :email =\> “removed\_email\_address@domain.invalid” } } }

The issue is that I can not create a symbol for 0 - :0 and :0.to\_sym  
don’t  
work and “0”.to\_sym and ‘0’.to\_sym give me the weird :“0”. So how can I  
hack  
this through? Is there another way to create such a hash which bypasses  
need  
for symbols which the controller will still understand?

Thanks,

David

You do not need it to be symbols I guess. I think that string will  
work just fine.  
Anyway. You can create symbols also this way:

:“123”

Thanks Robert, that worked great. Just looks a little weird at first to  
do  
:“0”.
