User Referral Program From Scratch Discussion

Just the thing I was needed for a current project, as usual, perfect timing Chris !

TIP: If any of you are using validations in devise, before_create in the user.rb file may not work, and you will get an error.

Therefore, try changing that line in user.rb to before_validation and you may find that it works.

Quick note here: you'll want to add a conditional check if self.referral_code.nil? to the make sure you don't re-generate and overwrite the existing referral code in the event a user needs to use the Forgot Password function.

You're correct @Monroe...I was getting an error with before_create claiming that the referral code already existed

Hi Charlie, so if someone clicks 'forgot password', that's going to have an effect on the referral code? Can you elaborate?

Hi Taylor, glad I was able to help!

hey guys i changed the before create to before validate and it works but think maybe the code will not generate a unique one every time and retry until it does?

Could someone explain the step by step on how it validates the codes uniqueness?

cheers

My understanding is that the method set_refferal_code that generates the code in the first place is ensuring that the code is unique. It will keep generating new codes, until it makes a unique one. I also found this article pretty helpful to learn about before and after methods. https://guides.rubyonrails.org/active_record_callbacks.html

I tried using it with omniauth : facebook and google it doesn't save the referred_by_id, any solution ?

When I try to create the new app using the jumpstart template, I land on this error

insert  config/webpack/environment.js
The file /Users/ijsemerene/Documents/GitHub/jumpstart/referral_app/config/webpack/environment.js does not appear to exist

Any ideas on how to address it?

Hey Ignacio,

If you look through the logs above, did it fail when installing webpacker?

Yup, looks like it's failing there first

Fantastic! glad I found this! was looking at different options and as always, cheaper to roll your own lol..!

Thanks again Chris!

Hi Chris! Any suggestion on how to proceed with the complete_reffral! method. I would like to give the referrer a free post without him having to go through stripe checkout for payment.

You can just call the complete_referral! method anytime the user completes the steps you want. If you want to do that right after registration, go add that after sign up. 👍

Any ideas on how one would go about adding this to a stripe checkout flow? I would like the referree to have a free post instead of going through the checkout if he has a referred user who has the referral_completed_at? as true.

Hi Chris! This referral program assumes that an user can only be referred once, right? What if two users reffer the same person? Thanks!

Only one referrer will get credit, typically that's the last referrer. That's how basically all referral programs work.
