relationship - Ruby on Rails relation output between 2 models -

i have 2 models. first events , second cities. in events table have column called city_id. want city name on each event show view.

in events controller:

@city = city.where(:id => @event.city_id) 

and in view:

<%= @city.name %> 

a city has many events , event belongs city.

the output in view word city.

hm, mistake?

change code from:

@city = city.where(:id => @event.city_id) 

to:

@city = @event.city 

besides being longer necessary, original code returns activerecord::relation object - lazy loaded query - collection of cities. calling @city.name getting class name relation - 'city'. work if added .first trigger query , first record:

@city = city.where(:id => @event.city_id).first 

but stated above, lot more code necessary ;). of course, assuming set belongs_to :city statement in event class.
