+# Specify New Attributes For #find_or_create_by
+
+The ActiveRecord
+[`#find_or_create_by`](https://apidock.com/rails/v4.0.2/ActiveRecord/Relation/find_or_create_by)
+method is a handy way to get an object that represents a record. It will
+attempt to look up that record, usually based on a unique value or set of
+values. If it can find one, then that's the record you get. If nothing is
+found, then it will create a new record.
+
+New records tend to need more data than just the unique lookup attribute. There
+are a couple ways these other attributes can be specified.
+
+The first is by giving `#find_or_create_by` a block.
+
+```ruby
+User.find_or_create_by(email: "some@email.com") do |new_user|
+  new_user.admin = false
+  new_user.password = params[:password]
+  new_user.password_confirm = params[:password_confirm]
+end
+```
+
+Another approach is to precede the `#find_or_create_by` call with a
+[`#create_with`](https://apidock.com/rails/ActiveRecord/QueryMethods/create_with)
+call.
+
+
+```ruby
+User.create_with(
+  admin: false,
+  password: params[:password],
+  password_confirm: params[:password_confirm]
+).find_or_create_by(email: "some@email.com")
+```
+
+In both cases, the extra attributes will not be applied to the `User` record in
+the case of a _find_; they are only used in the case of a _create_.
