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 reques 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 NewRelic

func NewRelic(key, name string) buffalo.MiddlewareFunc

NewRelic returns a piece of buffalo.Middleware that can be used to report requests to NewRelic. You must pass in your NewRelic key and a name for your application. If the key passed in is blank, i.e. loading from an ENV, then the middleware is skipped and the chain continues on like normal. Useful for development.

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.
