I posted on here as you guys are a lot more helpful than the books have been for me in the past! Please excuse as i am still learning.
I have a Landlord MGT App which has aa House model and a Tenant Model . On the show page for the house i would like to see the tenant which has the associated house_id in its model.
show page for house
.wrapper_with_padding
%h1.showheading= 'Property Information'
#house_show
%p First Line Address: #{@house.doorno} #{@house.house_title}
%p Description: #{@house.description}
%p Tenant: #{@tenant.house.tenant_id}
Currently the above line of code for Tenant does not work and pulls NULL value.
Models
class House < ActiveRecord::Base
belongs_to :user
belongs_to :tenant
class Tenant < ActiveRecord::Base
belongs_to :user
belongs_to :house
I have nothing in my controller for show.
In summary the tenant table has a house_id attribute. On the show page for that specific house i would like to see the associated tenant_id.
Thank you in advance
There's no reason for you to have @tenant
declared. You can access @house
's related tenant object via @house.tenant
and to get the id, just use @house.tenant.id
.
Edit: Your associations are wrong. See: https://guides.rubyonrails.org/association_basics.html#the-types-of-associations
Because Tenant has the column house_id, it belongs_to :house
.
That means that the house has_one :tenant
(can also be has_many
if you're into that sorta thing). Fix that, then try what I wrote above.
