About No Method Error
This is my own error resolution record.
The team implementation of flea market app creation is finally at the end. Merge what each member has developed into the master I often get an error when pulling to my local.

Occurs when trying to transition from My Page to Logout Page.
undefined method `each' for nil:NilClass
It is a description. Where is the place? Speaking of It is user # show.
When I check the controller immediately
class UsersController < ApplicationController
def index
@parents = Category.where(ancestry: nil)
end
def show
end
end
The contents of the show are empty ... Add description here
class UsersController < ApplicationController
def index
@parents = Category.where(ancestry: nil)
end
def show
@parents = Category.where(ancestry: nil)
end
end
When I did, the display returned properly.
By repeating errors, guess the cause from the error statement yourself It has become possible to solve it. Did I get a little self-propelled power?
It's still a long way to go, but I'll continue to do my best!
