I'm using Laravel 5.3. I've 4 tables.
Default Users table. Departments, Position, Employees tables.
Users table has ID | Email | Password
Departments table has ID | Department | User_Id - Here User_Id is foreign key comes from Users table's ID
Positions table has ID | Position | Department_Id - Here Department_Id is foreign key comes from Departments table's ID
Employees table has ID | Employee | Position_Id - Here Position_Id is foreign key comes from Positions table's ID
User can have multiple Departments. Departments can have multiple Positions, Positions can have multiple Employees. So, if user is different, how can i retrieve all data from all 4 tables which that user had created?
You can use nested eager loading:
$departments = Department::where('user_id', $id)
->with('positions', 'positions.employees')
->get();
Another way is to build simple queries:
$departments = Department::where('user_id', $id)->get();
$positions = Position::whereIn('department_id', $departments->pluck('id'));
$employees = Employee::whereIn('position_id', $positions->pluck('id'));

Hi I have 3 tables "temp_quotes", "quotes" and "quote_items"
Every quote generated goes to the "temp_quotes" table at first.
At the end of my multi-step form I need the following:
1- Receive all the quotes from the "temp_quotes" table, send it to the "quote_items" table and delete it from the "temp_quotes" table
2- Generate a new entry in the "quotes" table referencing the "users" table and
the "quote_items" table
Here is all the data and how needs to be save/removed on the tables:

USER_ID
QUOTE_ID
quote_items Table:
