Question

I have three tables Users(contains users details) users_shifts(contains users shift mapping) and shift(it’s id is in users_shift table).
What I’m doing is assigning multiple shifts to users and i want to retrieve all the data from users, users_shift and shift table.
I have done the following thing :

In user model:

has_many :users_shifts, :dependent => :destroy

In users_shift model :

has_one :shift
belongs_to :user

In Shift Model

belongs_to :users_shift

In controller i have :

User.all

Now i want to fetch all the data in a table in view.
I have to display users and his shift. Users detail will come from users table and shifts details will come from shifts table. Users_shift is used for users shift mapping.

Answer 1

try in your console first

@user_shifts = @user.users_shifts # by using this you get all users_shifts details for that particular user.
@shift = @user_shift.shift # by using this you will get shift for that paricular user_shift

same way you can also

@shift.user_shift # for getting details for users_shifts
@user_shifts.user # for getting details about user
