我正在创建更新配置文件表单。如何将数据库值设置为反应形式的初始值

updetail.component.ts

---

 this.leadForm = this.fb.group({
      fname: ['', [Validators.required, Validators.pattern(/^\S*$/)]],
      uphone: ['', [Validators.required, Validators.minLength(10), Validators.maxLength(10)]],
      project: ['', Validators.required],
      minvalue: ['', Validators.required],
      maxvalue: ['', Validators.required],
      followtime: ['', Validators.required],
      lname: ['', [Validators.required, Validators.pattern(/^\S*$/)]],
      uemail: ['', [Validators.required, Validators.email]],
      type: ['', Validators.required],
      status: ['', Validators.required],
  });
