Reporting issues / asking questions

I am really glad when I receive feedback and questions from you guys because this means my articles are interesting and useful. After all I am doing this for you as I really love teaching :).

Quite often I receive questions on how to extend some solution further or fix some kind of an error. I'm trying to be as helpful as possible but please help me a bit as well. So, when sending me a question via e-mail or when reporting an issue here on GitHub:

• Specify which article are we talking about.
• If you need help with an error, provide that error! This seems obvious but sometimes people just forget to do so.
• Error stack trace is always very much welcome.
• If possible, list some pieces of relevant code or provide a link to the GitHub repo if your project is open source. If, for some reason, you can't reveal your code (due to privacy policies, for example) - that's okay, we'll deal with this somehow.
• Try to overcome the problem yourself before contacting me and list the solutions you've already tried. Still, if you have absolutely no clue of what to do - go ahead and write me right away.
• If you are reporting an issue on GitHub, write in English because other people might experience the same problem. I am able to understand some other languages (Russian, Ukrainian, Polish), well, at some basic level at least, but still English is preferred.
• If you want me to cover a specific topic, try to provide some exact details on what has to be covered. Articles can't be too long and therefore topics like "how to write automated tests" or "how to write cool Rails apps" aren't suitable. There are many good books about Ruby and Rails in general out there :).

The more information you provide the faster we will be able to find a solution. Thank you for your understanding and please don't hesitate to contact me :).

Strong Params Changed

Hi @bodrovis .

I've found that rails has changed its way to permit a a field be on the whitelist.
Until now was:

application_controller.rb

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_up) << :name
  devise_parameter_sanitizer.for(:account_update) << :name
end

The new way that Devise has changed is:

def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
    devise_parameter_sanitizer.permit(:account_update, keys: [:name])
  end

I hope that this will help to get updated the tutorial.

Best!

Hi.
I just found this code. Is awesome.
But, the live example is not working. I've cloned the repository and isn't working too.
I'm getting this error:

The token is right.
Can u help me?

How can i do if i have 2 devise users models ?

Hey

At the first time, thank you so much for this code 👍
I need something similar on my app but I have 2 devise models users : Campeur and Proprietaire.

How can I do to implement this code on my app with my 2 users models ?

Some precisions :
In my app, Campeur can engage the conversation to Proprietaire. Campeur can't engage the conversation to another Campeur. Proprietaire can respond only if one Campeur engage the conversation. Proprietaire cant engage the conversation with another Proprietaire.
