Question

How to create an inline variable in the Play framework 2.x Scala template?
Path from the Play’s guide is not clear to me:

@defining(user.firstName + " " + user.lastName) { fullName =>
  <div>Hello @fullName</div>
}

Answer 1

First you don’t create a variable but a value meaning it’s read only.

In your example you have created a value fullName which is accessible inside the curly brackets.

@defining("Farmor") { fullName =>
  <div>Hello @fullName</div>
}

Will print Hello Farmor

To define a value which is accessible globally in your template just embrace everything with your curly brackets.

E.g.

@defining("Value") { formId =>
  @main("Title") {
    @form(routes.Application.addPost, 'id -> formId) {
      @inputText(name = "content", required = true)
      <input type="submit" value="Create">
    }
  }
}

In the example you can use the value formId anywere.
