+### NOT, LIKE, and NOT LIKE Conditions

+`NOT`, `LIKE`, and `NOT LIKE` SQL queries can be built by `where.not`, `where.like`, and `where.not_like` respectively.

+```ruby
+Post.where.not(author: author)

+Author.where.like(name: 'Nari%')

+In other words, these sort of queries can be generated by calling `where` with no argument, then immediately chain with `not`, `like`, or `not_like` passing `where` conditions.

-WARNING: Up to and including Rails 3.1, when the number of arguments passed to a dynamic finder method is lesser than the number of fields, say `Client.find_by_name_and_locked("Ryan")`, the behavior is to pass `nil` as the missing argument. This is **unintentional** and this behavior will be changed in Rails 3.2 to throw an `ArgumentError`.

 It's common that you need to find a record or create it if it doesn't exist. You can do that with the `find_or_create_by` and `find_or_create_by!` methods.
