Update the Pet object with the list of parameters returned from permit.

I am on step 4 of 5 on this challenge. below is the code I am using.
I have tried using just pet.update(pet_params) but it fails as well.

def update
        @pet = Pet.find(params[:id])
      params.require(:pet).permit(:name)  
      @pet = pet.update(pet_params)
  end
app/controllers/pets_controller.rb 
class PetsController < ApplicationController

  def show
    @pet = Pet.find(params[:id])
  end

  def edit
    @pet = Pet.find(params[:id])
  end

  def update
        @pet = Pet.find(params[:id])
      params.require(:pet).permit(:name)  
      @pet = pet.update(pet_params)
    end
end

This line of code worked for me!

def update
    @pet = Pet.find(params[:id])
    params.require(:pet).permit(:name)
    @pet.update(params)
  end

Your current problems are being caused by the code pet.update(pet_params) on line 14. There is no such variable as pet in your code; pet and @pet are two different variables. Did you mean @pet?

This is another way and what works for me too. I just want to share

def create # YOUR CODE HERE parametros = params.require(:pet).permit(:name) @pet = Pet.new(parametros) @pet.save redirect_to @pet

end
