Question

Currently, devise has the URLs as /users/sign_in although I’d like to change this to /signin.

In the routes.rb file, I’ve tried this:

devise_for :users do
    get "/signin" => "devise/sessions#new"
    match '/signin', :to => 'devise/sessions#new'
    get "/signout" => "devise/sessions#destroy"
    match '/signout', :to => 'devise/sessions#destroy'   
end

But nothing has worked. I get an error saying:

app/controllers/posts_controller.rb:19:in `show'

In the show section, I have

def show
  @post = Post.find(params[:id])

  respond_to do |format|
    format.html # show.html.erb
    format.json { render json: @post }
  end
end

What does show in the controller have to do with devise?

Try this one:

 devise_scope :user do
   get   "/signin"  => "devise/sessions#new"
   match '/signin'  => 'devise/sessions#new'
   get   "/signout" => "devise/sessions#destroy"
   match '/signout' => 'devise/sessions#destroy' 
 end
