Ketika saya membuat aplikasi ROR, pertamnya saya menggunakan scaffold
untuk mendapatkan struktur dari controller, model, dan viewnya..
kemudian saya mengubah dibagian controller -> def show karena ketika
digenerete dari scaffold def show tersebut hanya menampilkan berdasaran
Id (params[:id]).
Pada aplikasi yang saya bangun saya menggunakan tabel Employees,
kemudian saya generete scaffold mode Employee, controller jg employee.
pada tabel employee terdapat field2: nip, nama, alamat. pada waktu
scaffol pada employee_controller.rb method show menampilkan berdasarkan id.
pada aplikasi ini saya mengubah menjadi nip dengan code seperti dibawah ini:
code pada controller:
employee_controller.rb
def show
@employee = Employee.find_nip
end
code pada model:
employee.rb
def self.find_nip(no)
find(:all, :conditions => ["nip = ?",no])
#find_by_sql("select * from employees where nip=1")
end
terus ketemu error yang seperti ini
ArgumentError in EmployeeController#show
Wrong # of arguments(0 for 1)
