Ruby on Rails

I am getting Id missing nil error in my create controller spec. Yet I have passed ID stuff in it still facing same everything. Here my create spec and controller file

Create Spec

  describe 'POST :create' do

    context 'with valid data' do

      let(:valid_data) { FactoryGirl.attributes_for(:student) }

      it 'redirect to show page' do

        post :create, student: valid_data

        expect(response).to redirect_to(student_path(assigns[:student]))

      end

    end

  end

Student Controller 

  def create

    @student = current_user.students.build(student_params)

    respond_to do |format|

      if @student.save

        format.html { redirect_to @student }

        format.json { render :show, status: :created, location: @student }

      else

        format.html { render :new }

        format.json { render json: @student.errors, status: :unprocessable_entity }

      end

    end

  end

private

  def student_params

    params.require(:student).permit(:Student_Prefix, :First_Name, :Middle_Name, :Last_Name, :Father_Prefix, :Father_Name, :Father_Middle_Name, :Father_Last_Name, :Mother_Prefix, :Mother_Name, :Mother_Middle_Name, :Mother_Last_Name,  :user_id)

  end

Error

1) StudentsController POST :create with valid data redirect to show page

   Failure/Error: expect(response).to redirect_to(student_path(assigns[:student]))

   

   ActionController::UrlGenerationError:

     No route matches {:action=>"show", :controller=>"students", :id=>nil} missing required keys: [:id]

   # ./spec/controllers/students_controller_spec.rb:38:in `block (4 levels) in <top (required)>'

   # -e:1:in `<main>'
