Definition

type alias View model =
{ hasError : Bool
, hasModified : Bool
, form : model
}

models and that has error, has modified

type alias Model form opts =
Model form { opts | isModified : Bool }

field name, form and errors

type alias Single form opts a =
Model (Form form a) opts

single form model

type Attribute a

attribute of conflict state and resolve operation

type alias Field a =

conflict attribute field

type alias Form form a =
{ field : Field a
, prop : Prop form a
, last : a
}

field, prop and last value

type alias Prop form a =
Prop form (Attribute a) a

Prop for conflict attribute field

type alias Getter response a =
response -> a

response to value getter

type alias Options form response =
{ error : String
, form : form
, response :
{ first : Maybe response
, last : response
}
}

initialize options

{ error : String -- error message
, form  : form   -- fields
, response :
  { first : Maybe response -- response of edit start
  , last  : response       -- last response
  }
}
type State lastValue
= NoProblem
| Conflict lastValue

conflict state

type Resolve value

resolve type

Construction

init : String -> value -> String -> Field value

construct Field

"name" |> Conflict.init signature ""
List (Maybe String)
-> ( Prop form a, Getter response a )
-> Options form response
-> Model (Form form a) {}

construct Single

{ error = "conflict"
, form  = form
, response =
  { first = form.response
  , last  = http.response
  }
}
|> ( ( name_, get_name ) |> Conflict.single [ form.name |> Validate.blank "blank" ] )

Getter

state : Form form a -> State a

get conflict state

form |> Conflict.state

Setter

toConflict : a -> Field a -> Field a

set conflict

Resolve

resolve : Prop form a -> Resolve a -> form -> form

resolve conflict

model |> Conflict.resolve prop Conflict.leave
model |> Conflict.resolve prop (Conflict.revert value)

leave editing value

revert : a -> Resolve a

revert original value

Helper

compose : (Model a opts -> model) -> Model a opts -> View model
