How to extract all form fields at once?

[Fedor Tokarev]

Hello,

I've found this page https://github.com/spray/spray/wiki/Form-Field-Filters, where it is noted that I can do this:

content(as[FormData]){ formData =>

}

But that wiki is about 0.9.0 -- a lot of things has happened since then. What is a current way to extract all form fields at once?

[Fedor Tokarev]

Solution:

  def allFormFields: Directive[Map[String,String] :: HNil] = {

    extract(_.request.entity.as[FormData].right.map(_.fields)).flatMap{

      case Right(value) => provide(value)

      case Left(_) => reject

    }

  }

Fedor,

actually you might want to use the `entity` directive as such:

entity(as[FormData]) { formData =>
...
}

Still, your implementation suggestion is pretty close to how the `entity` directive is implemented:
https://github.com/spray/spray/blob/master/spray-routing/src/main/scala/spray/routing/directives/MarshallingDirectives.scala#L36

Cheers,
Mathias
