Why is my authentication not allowing me to log in? - ruby-on-rails

Question

Trying to figure out why authenication isn't working properly for my code even with gem devise. My login page displays properly but when it comes to logging in with an existing user's info located in the seeds.rb file, it prints out the else statement instead of directing to the home page.
def sign_in
page = User.find_by(email: params[:email])
if page.present? && page.authenticate(params[:password])
session[:user_id] = page.id
redirect_to root_path, notice: "You have successfully logged in"
else
flash[:alert] = "Invalid info"
redirect_to login_path
end
end
I changed the user.authenicate(params[:password]) to page.authenicate(params[:password]) but the same issue was still showing.

This is the first clue from your log...
SELECT "users".* FROM "users" WHERE "users"."email" IS NULL
params[:email] is null, because the email parameter is in a form called session, which you can see in the log...
"session"=>{"email"=>"hi#email.com", "password"=>"[FILTERED]"}, "commit"=>"Login"}
so your code needs to use form name to access the email and password parameters properly...
def sign_in
user = User.find_by(email: params[:session][:email])
if user.present? && user.authenticate(params[:session][:password])
session[:user_id] = user.id
redirect_to root_path, notice: "You have successfully logged in"
else
flash[:alert] = "Invalid info"
redirect_to login_path
end
end
