Hey all been working on my first app that is to help track projects
and who's working on them. I want to be able in the project
controller find employees in the employee controller by project_id,
and then list them on my show defenition.
I thought this would work but ofcourse it doesn't and I can't find any
examples in my google searches.
def show
@project = Project.find(params[:id])
@employees = Employee.find(params[:project_id])
end
If I change the @employees to Employee.find(:all) it will just list
all employees even if they don't associate with the project.
Have a look at the rails guide on active record associations (assuming
you have already worked through the getting started guide. I imagine
that you want a has_and_belongs_to_many association between project
and employees. Once you set this up then if you have a project in
@project then @project.employees will give you an array of employees
working on the project. Similarly if you have an employee then
@employee.projects will tell you the projects he/she is working on.
Such is the magic of rails.
