我是玩 2.0 的新手。我创建了一个注册表单,现在我尝试创建一个搜索表单。但我被这个抓住了error: " Missing parameter in call definition: String In /home/thangnk/Task/conf/routes at line 17. "
。
这是我的代码:
控制器 --- Search.java
package controllers;
import java.util.ArrayList;
import java.util.List;
import models.Task;
import play.*;
import play.data.Form;
import play.db.ebean.Model.Finder;
import play.mvc.*;
import views.html.*;
public class Search extends Controller{
static Form<Task> myform = form(Task.class);
public static Result search(){
return ok(search.render());
}
public static Result searchByusername(String username){
Form<Task> filledForm = myform.bindFromRequest();
username=filledForm.get().username;
return ok(result_search.render(username));
}
}
模型---Task.java
package models;
import java.util.*;
import javax.persistence.Entity;
import javax.persistence.Id;
import play.data.validation.Constraints.Email;
import play.data.validation.Constraints.MaxLength;
import play.data.validation.Constraints.MinLength;
import play.data.validation.Constraints.Required;
import play.db.ebean.Model;
import play.db.ebean.Model.Finder;
@Entity
public class Task extends Model {
@Id
public static Long id;
// @Required
// @MinLength(6)
// @MaxLength(12)
public String password;
@Email
public String email;
// @MinLength(6)
public String username;
public Task() {
}
public Task(Long id, String username, String email, String password) {
this.email = email;
this.username = username;
this.id = id;
this.password = password;
}
public static Finder<Long, Task> find = new Finder(Long.class, Task.class);
public static List<Task> all() {
return find.all();
}
public static void create(Task task) {
task.save();
}
public static void delete(Long id) {
find.ref(id).delete();
}
public static List<Task> searchByusername(String name) {
return find.where().like("username", "%" + name + "%").findList();
}
}
