Elm-spa.dev -- how to access global model in a page view?

cbrake · February 24, 2020, 10:50pm

Hi,

I’m learning https://www.elm-spa.dev and find it very helpful to understanding how to set up multi-page apps in Elm.

I do have one question – if I want to access data in the global model in a page view, how do I do that?

For example:

ryannhg/elm-spa/blob/master/examples/complex/src/Pages/SignIn.elm

module Pages.SignIn exposing (Model, Msg, page)

import Spa.Page
import Components.Button
import Utils.Styles as Styles
import Element exposing (..)
import Element.Border as Border
import Element.Font as Font
import Element.Input as Input
import Generated.Params as Params
import Global
import Html exposing (Html)
import Html.Attributes as Attr
import Html.Events as Events
import Utils.Spa exposing (Page)


type alias Model =
    { username : String
    , password : String

This file has been truncated. show original

only the page model is passed into the view. Is there any way to access the global model, or am I thinking about this wrong?

Thanks,
Cliff

Remove the always function from line 41, then you have access to PageContext and can use the view this way:

view : Utils.Spa.PageContext → Model → Element Msg
view { global, route, queryParameters } model =
