Rails SQL in controller -

-

i'm using xeditable , rabl in rails app.

i have workorder belongs workgroup. want assign workorder employee in workgroup.

i'm using source in xeditable:

data-source="/employees.json?workgroup=<%= workorder.workgroup.id%>"

and code i'm trying in employee controller:

  def index     @employees = employee.order(:first_name)     @employees = employee.joins(:empgroups).where(:workgroup_id => params[:workgroup]) if params[:workgroup].present?   end

this sql gets generated:

select "employees".* "employees" inner join "empgroups" on "empgroups"."employee_id" = "employees"."id" "employees"."workgroup_id" = 2

the issue should `where "empgroups"."workgroup_id" = 2

how change line of code?

@employees = employee.joins(:empgroups).where(:workgroup_id => params[:workgroup]) if params[:workgroup].present?

thanks help!

you can use nested hash syntax: 

@employees = employee.joins(:empgroups).where(   empgroups: { workgroup_id: params[:workgroup] } ) if params[:workgroup].present?
