Re: how to adress specific data from related models?

Hello again, Jeremy,

sadly inside the posted data there is only the lodging_id.
How do I get the value for numberofbeds fromthe lodging-model?

As the validation is inside the bookingpositions model
and the bookingpositions model only has the lodging_id
how do i get the attribute numberofbeds from the lodging with
id=lodging_id?

Thanks

Michael

Then it's a case of accessing the right part of the array to get the values you want.
