New features

Minor features

Models and databases

• Query sets now provide a #limit method and an #offset method. Those methods respectively allow to limit the number of records returned and to offset the records returned. They act as aliases for the #[] method with a range.
• The #update query set method can now be called on model classes directly, thus allowing to update all the records of the considered model with the specified values.
• It is now possible to update only specific columns without running validations or callbacks for a model record by using the #update_columns method.
• It is now possible to easily create or update records in a single call by using the #update_or_create query set method. An #update_or_create! variant is also available for the same purpose, but it raises in case updated/created records are invalid.

Handlers and HTTP

• Marten::HTTP::UploadedFile objects can now be serialized to JSON.
• A convenient #remote_ip_address method was added to the Marten::HTTP::Request class, allowing to easily retrieve the remote IP address of the incoming request.

Templates

• Most informational string properties (such as #ascii_only?, #blank?, #bytesize, #empty?, #size, and #valid_encoding?) are now available as template attributes for string values and safe string values.

Development

• The flash store can now be accessed from the spec client by using the #flash method. See Flash messages for more details.
