Restful Routes Example

restful_bands.rb

##
## RESTful routes for 2 resources:
# 1) Sessions
# 2) Bands
#
# Note: In order to use the 'other' HTTP verbs (put & delete) you need to enable the
# method_override feature of Sinatra.
#
# (in config/environment.rb)
# config do
#   set :method_override, true
#
# end
#
#
# Don't forget to include the hidden _method input on forms
# you want to use a non-get/post http verb. e.g.
#
# <form action="/band/<%[email protected]%>" method="post">
#   <input type="hidden" name="_method" value="delete"/>
#
#   <input type="submit" value="Delete Band with id: <%[email protected]%>"/>
# </form>


# Show the login page
get "/sessions/new" do
  erb :"sessions/new"
end

# Create a new session (log the user in)
post "/sessions" do
  @user = User.find(email: params[:email])
  @user.authenticate(params[:password])

  session[:user_id] = @user.id

  redirect "/users/#{@user.id}"
end

# Delete a session (clear the session cookie)
delete "/sessions" do
  session.clear

  redirect "/sessions/new"
end




# Read
#
# show all bands (index)
get "/bands" do
  @band = Band.all

  erb :"bands/index"
end

# show one band by id (show)
get "/bands/:id" do
  @band = Band.find(params[:id])

  erb :"bands/show"
end

# show the form to create a new
get "/bands/new" do
  erb :"bands/new"
end

# create a new band record (create)
post "/bands" do
  @band = Band.new(params[:band])

  if @band.save
    redirect "/bands"
  else
    erb :"bands/new"
  end
end


# Update
#
# show the form to edit a band
get "/bands/:id/edit" do
  @band = Band.find(params[:id])

  erb :"/bands/edit"
end

# update the band by id (update)
put "/bands/:id" do
  @band = Band.find(params[:id])
  # params => {id: 3, band: {name: "The Killers", member_count: 4}, _method: "put"}
  if @band.update(params[:band])
    redirect "/bands/#{@band.id}"
  else
    erb :"bands/edit"
  end
end


# delete a band by id (destroy)
delete "/bands/:id" do
  @band = Band.find(params[:id])
  @band.delete

  redirect "/bands"
end
