PopTransaction is a piece of Buffalo middleware that wraps each request in a transaction that will automatically get committed or rolledback. It will also add a field to the log, "db", that shows the total duration spent during the request making database calls.

Functions

func AddContentType

func AddContentType(s string) buffalo.MiddlewareFunc

AddContentType will add a secondary content type to a request. If no content type is sent by the client the default will be set, otherwise the client's content type will be used.

func ParameterLogger

func ParameterLogger(next buffalo.Handler) buffalo.Handler

ParameterLogger logs form and parameter values to the logger

func SessionSaver

func SessionSaver(next buffalo.Handler) buffalo.Handler

SessionSaver is deprecated, and will be removed in v0.10.0. This now happens automatically. This middleware is no longer required.

func SetContentType

func SetContentType(s string) buffalo.MiddlewareFunc

SetContentType on the request to desired type. This will override any content type sent by the client.
