rails devise valid_password

# Step 1: Include Devise in your model
class User < ApplicationRecord
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
end

# Step 2: Use valid_password? method to check if the provided password is valid
user = User.find_by(email: '[email protected]')
password_valid = user.valid_password?('password123')

# Explanation for Step 1:
# - Include Devise in the User model using the 'devise' method.
# - Specify the authentication modules you want to use, such as ':database_authenticatable' for password-based authentication.
# - Other modules like ':registerable', ':recoverable', ':rememberable', and ':validatable' provide additional features.

# Explanation for Step 2:
# - Find the user by their email or any other unique identifier.
# - Use the 'valid_password?' method to check if the provided password ('password123' in this example) is valid for the user.
# - The 'valid_password?' method returns a boolean indicating whether the password is valid.
