edit.scala.html
#import models.auth.Users
#(title: String, user:models.auth.User)
#main(title){
<form method="post" action="#controllers.auth.routes.UserController.update(Users.toLong(user.id))">
<input type="text" placeholder="First Name" name="firstName" value="#user.firstName"/><br/>
<input type="text" placeholder="Last Name" name="lastName" value="#user.lastName"/><br/>
<input type="email" placeholder="Email" name="email" value="#user.email" /><br/>
<input type="text" placeholder="Phone" name="phone" value="#user.phone" /><br/>
<input type="text" placeholder="Birthdate(dd/MM/yyyy)" name="birthDate" value="#user.birthDate" /><br/>
<input type="text" placeholder="Username" name="username" value="#user.username" /><br/>
<input type="submit" value="Update User" />
</form>
}
routes
POST /user/:id/ controllers.auth.UserController.update(id:Long)
I already done for create, read and delete, but for update i found error in line
var user = simpleUserForm.bindFromRequest.get
the error is NoSuchElementException: None.get

Answer 1

The Play page on Scala Forms is helpful here. That approach would be to send the populated form to the view as a parameter, then on submit use fold, which gives you options to deal with the error case as well as the "happy" case. Something like the following (adapted from the above page):
simpleUserForm.bindFromRequest.fold(
formWithErrors => {
// binding failure, you retrieve the form containing errors:
// in your form, test .hasErrors
BadRequest(views.html.user.edit(formWithErrors))
},
userData => {
/* binding success, you get the value. */
// .. do the update
...
//-- and return to list or home or...
Redirect(routes.Application.home(id))
}
)
If you don't want to use the form, then to back to your actual question, would .getOrElse not work?

did you import
import play.api.libs.concurrent.Execution.Implicits._
