controller:
def addpost = action{ implicit request => ok(views.html.newpost(postform)) } def createpost = action { implicit request => postform.bindfromrequest.fold( haserrors => badrequest, success => { post.create(post(new date, success.title, success.content)) ok(views.html.archive("my blog", post.all)) }) } routes:
get /archive/new controllers.application.addpost post /archive controllers.application.createpostview:
@(postform: form[post])(content: html)(implicit messages: messages) @import helper._ @form(routes.application.createpost) { @inputdate(postform("date")) @textarea(postform("title")) @textarea(postform("content")) <button id="submit" type="submit" value="submit" class="btn btn-primary">submit</button> } update
i solved problem adding following imports in controller file:
import play.api.i18n.messages.implicits._ import play.api.play.current see play 2.4 migration: https://www.playframework.com/documentation/2.4.x/migration24#i18n
compilation error
your view expects 3 parameters passed, passing one. solve compilation error, change signature in view from@(postform: form[post])(content: html)(implicit messages: messages) @(postform: form[post])(implicit messages: messages).
parameters , views
the second parameter in example (content: html) used when combine several views:
index.scala.html
@(text: string) @main("fancy title") { <div>@text</div> } main.scala.html
@(title: string)(content: html) <html> <head> <title>@title</title> </head> <body> @content <body> </html> call in controller
ok(views.html.index("some text")) in example passing "some text" index view. index view calls main view passing 2 parameters. title , content, content html in between curly braces of index.scala.html (<div>@text</div>)
finally implicit parameters: (implicit messages: messages) must somewhere in scope passed implicitly view. example in controller:
def addpost = action{ implicit request => implicit val messages: messages = ... ok(views.html.newpost(postform)) }
