[Rails] Sign-up function using devise error number of arguments (given 0, expected 1)

Error details

When I installed devise and performed sign-up, I got an error like this.

ArgumentError (wrong number of arguments (given 0, expected 1)):
wrong number of arguments (given 0, expected 1)

Solution

user.rb


has_secure_password

Erase. has_secure_password is a rails function that encrypts and saves the password when it is saved in the DB. It is not necessary when using devise, so comment it out.
