How to redirect/ render to another controller's view?

Once the pet is saved, I want to redirect to treats/show controller. I tried doing this but it takes me back to pets/show.

def create
    @pets = Pet.new(pet_params)

    respond_to do |format|
      if @pet.save
        format.html { redirect_to @treat}
        format.json { template: treats/show, status: :created, location: @pet }
      else
        format.html { render :new }
        format.json { render json: @pet.errors, status: :unprocessable_entity }
      end
    end
end

  1. Your @pets variable should be @pet...

Like this:

def create
   @pet = Pet.new pet_params

--

2. You aren't defining your @treat variable:

@treat = Treat.find params[:treat_id] ?

This is shown up here:

{:action=>"show", :controller=>"treat", :id=>nil}

So the answer is that you need to define @treat. Because I don't know your associations, or how you want @treat to be populated, there are two ways to create it:

Either pull it from the association (IE @pet.treat) or invoke it explicitly: (@treat -)...

For simplicity, you're best doing the following:

def create
    @pets = Pet.new pet_params 
    @treat = Treat.find [[[num - where do you get this from?]]]

    ...
end

--

If you had your models set up as such:

#app/models/pet.rb
class Pet < ActiveRecord::Base
   has_many :treats
end

#app/models/treat.rb
class Treat < ActiveRecord::Base
   belongs_to :pet
end

You could use the following:

def create
    @pet = Pet.new pet_params
    @treat = @pet.treat.new treat_params

    respond_to do ...

end

private

def treat_params
   params.require(:treat).permit(:treat, :params)
end

You would do this for your redirect path:

format.html  { redirect_to(treat_path(@treat) }
