Add a token field to the feedback model with an index and add a callback to populate it on create e.g. feedback.rb
before_create :add_token
private
def add_token
begin
self.token = SecureRandom.hex[0,10].upcase
end while self.class.exists?(token: token)
end
now add a new route for the providers feedback
resources :feedbacks do
get 'provider'
put 'provider_update' # you might not need this one, if you are happy to use update
end
In your controller make sure they don't get rejected by devise
before_filter :authenticate_user!, except: [:provider, :provider_update]
...
def provider
@feedback = Feedback.find_by token: params[:token]
end
then in the app/views/feedback/provider.html.haml you can use url in simple_form to send it to the correct update location and only provide the input that they should see.
f.inputs :p_comment
Now update your mailer.
@url = provider_feedback_url(@feedback, token: @feedback.token)
You could do something similar to this using friendly id but you would still need to create some sort of unique slug and then use Feedback.friendly.find instead. I think you would want to combine it with a token to ensure it's still the provider giving the feedback - so the only benefit would really be hiding the true id/count. I think you should update p_* fields to provider_* so that the next dev knows what's in it - it's not the 90s!
