Hi,
I'm trying to understand belongs_to and has_many etc... I understand the
relationship but I'm trying to figure how this can help me
for example I have two tables
i have 2 tables called mothers and another called childrens
in this childrens model i have this
###Childrens model
belongs_to: mother
..
..
####
now in the
children controller
I want to retrive the mother name currently I'm doing this way
def index ##show all the childrens and their mother's name
@childrens = Childrens.find(
:all,
:select=>"mothers.name AS mother_name, childrens.* ",
:join=>"LEFT JOIN mothers ON mothers.id = childrens.mother_id"
)
end
I was just curious because of the belongs_to I can skip this left join
on tables
