Let's examine the contents of the User model once. ↓ Contents of User model
name: "Shota Fujita",
email: "[email protected]",
password_digest: [FILTERED],
admin: false,
image: nil,
It seems that the cause is that the value of ʻimage is nil`.
Find the user who is nil with rails c etc. and delete it.
Add the following to ʻimage_uploader.rb`.
app/uploaders/image_uploader.rb
def default_url(*args)
'default.png'
end
Put the images in ʻapp / assets / images` and you're done.
