Player edit view

We created a ChangeLevel message. Let's trigger this message from the player's edit view.

In src/Players/Edit.elm change btnLevelDecrease and btnLevelIncrease:

...
btnLevelDecrease : Player -> Html Msg
btnLevelDecrease player =
    a [ class "btn ml1 h1", onClick (ChangeLevel player.id -1) ]
        [ i [ class "fa fa-minus-circle" ] [] ]


btnLevelIncrease : Player -> Html Msg
btnLevelIncrease player =
    a [ class "btn ml1 h1", onClick (ChangeLevel player.id 1) ]
        [ i [ class "fa fa-plus-circle" ] [] ]

In these two buttons we added onClick (ChangeLevel player.id howMuch). Where howMuch is -1 to decrease level and 1 to increase it.
