Customization of validation

Overview

While creating a personal app, an event occurred that suddenly made it impossible to register as a group: scream:

The cause was the validation I added to the users model: persevere: (To find the cause, I created the app from scratch and spent 4 days talking about it ...)

I will leave it as a memorandum!

Error status

Group registration screen

log

Looking at the log, the params are ROLLBACKed even though the data is properly retrieved: rolling_eyes: The content of the error is ** invalid **.

Cause

The bad code was the validation I added to the users model: angry:

app/models/user.rb

  validates :password, presence: true, length: {minimum: 8 }

Password 7 characters or less is a description that causes an error.

Perhaps the validation added to the user model made it necessary to get password data when registering a group? ?? Is it? ?? If anyone knows, please let me know: bow_tone1:

Solution

I solved it by adding an option to the validation added to the users model!

app/models/user.rb

  validates :password, presence: true, length: {minimum: 8 },on: :create

Validation is used only when registering as a user! It means that.

Impressions

First of all, it is an event that the cause is found by recreating the application from scratch in the situation where registration is suddenly impossible and the cause is unknown. .. .. It was really painful: sob: I solved it by adding only 11 character code, but I think I got a lot of things in a way: laughing:
