You got all the apartments in the database. Now you run the sql to get the apartments object.
Then iterate each apartment and link it to house with the association.

This is done as follows:

def index
        @apartments = Appartment.all

    @apartments.each do |apartment|
       #this is giving you the link to house via association defined.
         apartment.house 

       #this is giving you the value of the field say `house_name` of house table that is linked to apartment.

         @house_name = apartment.house.house_name
      .
      .
      .
    end
end

Try this:

<%= link_to 'House', house_path(apartment.house) %>

or 

<%= link_to 'House', house_url(apartment.house) %>
