Check argument passed to ActiveSupport::Cache#fetch_multi

ActiveSupport::Cache#fetch_multi raises an ArgumentError if no block passed to it, because it has to write the returned data to the cache. If you don't want that, you should use read_multi.

Fix JSON attribute seralization

This commit fixes a bug with the JSON serialization where nil values where stored as json 'null' instead of SQL NULL, and broke queries searching for NULL values.

Return true if attribute is not changed for update_attribute

update_attribute returns correctly true now when the attribute isn't changed.

Always store errors details information with symbols

When the association is autosaved the details were stored with string keys, which caused some inconsistency with Errors#add and Errors#messages, but it is fixed now.

Fix memoization bug on ActionDispatch::TestRequest#request_method=

ActionDispatch::TestRequest#request_method was memoized before this change and caused a bug if you wanted to override it.
