好像您忘记导入模型了。@main
尝试在事情之前添加这个:
@import your.package.Customer
@import your.another.package.Order
或者您可以像这样导入整个包:
@import your.package._
编辑:是的,我想这行@(customer: Customer, orders: List[Order])
应该是你视图中的第一行,而不是@main
行之后,所以它可能应该是这样的:
@(customer: Customer, orders: List[Order])
@import your.package._
@main("welcome") {
<h1>Welcome @customer.name!</h1>
<ul>
@for(order <- orders) {
<li>@order.getTitle()</li>
}
</ul>
}
在您的Application.java中,您需要将customer
和orders
参数传递到视图中:
public static Result index() {
response().setContentType("text/html");
return ok(index.render(SomeService.instance().getCustomer(), SomeAnotherService.instance().getOrders()));
}
编辑 2:好的,这就是你可以这样做的方法。
Customer 和 Order 类可能在同一个包中,模板中的导入与简单的 java\scala 导入完全相同。
例子:
客户.java
package models;
public class Customer {
public String name; //as you use @customer.name thing, the field should be public
}
订单.java
package models;
public class Order {
private String title; //we can make it private because you use the getter in the template
public String getTitle() {
return this.title;
}
public void setTitle(String title) {
this.title = title;
}
}
应用程序.java
import models.*;
import static java.utils.Arrays.*;
....
public static Result index() {
response().setContentType("text/html");
Customer customer = new Customer();
customer.name = "serejja";
Order order1 = new Order();
order1.setTitle("my order 1");
Order order2 = new Order();
order2.setTitle("my order 2");
java.util.List orders = asList(order1, order2);
return ok(index.render(customer, orders));
}
index.scala.html
@(customer: Customer, orders: List[Order])
@import models._
@main("welcome") {
<h1>Welcome @customer.name!</h1>
<ul>
@for(order <- orders) {
<li>@order.getTitle()</li>
}
</ul>
}
