Hello,

I have the following scenario:

Models:

provider (has\_and\_belongs\_to\_many)  
level (has\_and\_belongs\_to\_many)  
levels\_providers

At the moment, I’m attempting a page that will list all of the  
providers. I have this working perfectly, but I want each provider that  
is listed to also list the levels that are associated with it. I haven’t  
been able to get my head around this. I can provide more information,  
but I’m not sure where to go at this point. Thanks for any help!

Jonathan

Assuming the models are set up correctly each provider object can  
access it’s levels in something similar to:

for level in provider.levels do  
#stuff  
end

provider.levels should give you every level associated with that  
provider.

Similarly, level.providers will give you all the providers associated  
with any given leve.
