开发准备
上一篇文章中我们实现了项目端云一体化金刚区活动模块，数据也成功的从云端获取，并且我们跟 ScrollBar 进行关联，能够让用户直观的查看当前滑动的位置。现在我们开始继续向下，随着我们首页的内容越来越多，我们如果因为某些业务需要进行调整和下线，想隐藏和关掉某些模块，就需要每次在打包的时候进行处理，这很明显会非常的麻烦，现在我们通过一张表来对首页的整个模块进行控制，这样每次做展示的时候去进行查询当前状态来实现想要的效果。
代码实现首先我们先创建一个表把所有的关联 id 以及模块的状态字段定义一下
{"objectTypeName": "home_activity_setting","fields": [{"fieldName": "id", "fieldType": "Integer", "notNull": true, "belongPrimaryKey": true},{"fieldName": "poster_id", "fieldType": "Integer"},{"fieldName": "banner_id", "fieldType": "Integer"},{"fieldName": "good_left_id", "fieldType": "Integer"},{"fieldName": "good_right_id", "fieldType": "Integer"},{"fieldName": "goods_list_id", "fieldType": "Integer"},{"fieldName": "new_people_status", "fieldType": "Boolean"},{"fieldName": "split_layout_status", "fieldType": "Boolean"},{"fieldName": "banner_status", "fieldType": "Boolean"},{"fieldName": "goods_list_status", "fieldType": "Boolean"}
],"indexes": [{"indexName": "field1IndexId", "indexList": [{"fieldName":"id","sortType":"ASC"}]}],"permissions": [{"role": "World", "rights": ["Read"]},{"role": "Authenticated", "rights": ["Read", "Upsert"]},{"role": "Creator", "rights": ["Read", "Upsert", "Delete"]},{"role": "Administrator", "rights": ["Read", "Upsert", "Delete"]}]}然后我们创建数据
{"cloudDBZoneName": "default","objectTypeName": "home_activity_setting","objects": [{"id": 1,"poster_id": 1,"banner_id": 1,"good_left_id": 1,"good_right_id": 1,"goods_list_id": 1,"new_people_status": true,"split_layout_status": true,"banner_status": true,"goods_list_status": true}]}现在进行实体类的创建
export class HomeActivitySetting {id: number;poster_id: number;banner_id: number;good_left_id: number;good_right_id: number;goods_list_id: number;new_people_status: boolean;split_layout_status: boolean;banner_status: boolean;goods_list_status: boolean;
constructor() {}
getFieldTypeMap(): Map<string, string> { let fieldTypeMap = new Map<string, string>(); fieldTypeMap.set('id', 'Integer'); fieldTypeMap.set('poster_id', 'Integer'); fieldTypeMap.set('banner_id', 'Integer'); fieldTypeMap.set('good_left_id', 'Integer'); fieldTypeMap.set('good_right_id', 'Integer'); fieldTypeMap.set('goods_list_id', 'Integer'); fieldTypeMap.set('new_people_status', 'Boolean'); fieldTypeMap.set('split_layout_status', 'Boolean'); fieldTypeMap.set('banner_status', 'Boolean'); fieldTypeMap.set('goods_list_status', 'Boolean'); return fieldTypeMap;}
getClassName(): string { return 'home_activity_setting';}
getPrimaryKeyList(): string[] { let primaryKeyList: string[] = []; primaryKeyList.push('id'); return primaryKeyList;}
getIndexList(): string[] { let indexList: string[] = []; indexList.push('id'); return indexList;}
getEncryptedFieldList(): string[] { let encryptedFieldList: string[] = []; return encryptedFieldList;}
setId(id: number): void { this.id = id;}
getId(): number { return this.id;}
setPoster_id(poster_id: number): void { this.poster_id = poster_id;}
getPoster_id(): number { return this.poster_id;}
setBanner_id(banner_id: number): void { this.banner_id = banner_id;}
getBanner_id(): number { return this.banner_id;}
setGood_left_id(good_left_id: number): void { this.good_left_id = good_left_id;}
getGood_left_id(): number { return this.good_left_id;}
setGood_right_id(good_right_id: number): void { this.good_right_id = good_right_id;}
getGood_right_id(): number { return this.good_right_id;}
setGoods_list_id(goods_list_id: number): void { this.goods_list_id = goods_list_id;}
getGoods_list_id(): number { return this.goods_list_id;}
setNew_people_status(new_people_status: boolean): void { this.new_people_status = new_people_status;}
getNew_people_status(): boolean { return this.new_people_status;}
setSplit_layout_status(split_layout_status: boolean): void { this.split_layout_status = split_layout_status;}
getSplit_layout_status(): boolean { return this.split_layout_status;}
setBanner_status(banner_status: boolean): void { this.banner_status = banner_status;}
getBanner_status(): boolean { return this.banner_status;}
setGoods_list_status(goods_list_status: boolean): void { this.goods_list_status = goods_list_status;}
getGoods_list_status(): boolean { return this.goods_list_status;}
static parseFrom(inputObject: any): HomeActivitySetting { let result = new HomeActivitySetting(); if (!inputObject) { return result; } if (inputObject.id) { result.id = inputObject.id; } if (inputObject.poster_id) { result.poster_id = inputObject.poster_id; } if (inputObject.banner_id) { result.banner_id = inputObject.banner_id; } if (inputObject.good_left_id) { result.good_left_id = inputObject.good_left_id; } if (inputObject.good_right_id) { result.good_right_id = inputObject.good_right_id; } if (inputObject.goods_list_id) { result.goods_list_id = inputObject.goods_list_id; } if (inputObject.new_people_status) { result.new_people_status = inputObject.new_people_status; } if (inputObject.split_layout_status) { result.split_layout_status = inputObject.split_layout_status; } if (inputObject.banner_status) { result.banner_status = inputObject.banner_status; } if (inputObject.goods_list_status) { result.goods_list_status = inputObject.goods_list_status; } return result;}
复制代码
}
db 类 import { cloudDatabase } from '@kit.CloudFoundationKit';
class home_activity_setting extends cloudDatabase.DatabaseObject {public id: number;public poster_id: number;public banner_id: number;public good_left_id: number;public good_right_id: number;public goods_list_id: number;public new_people_status: boolean;public split_layout_status: boolean;public banner_status: boolean;public goods_list_status: boolean;
public naturalbase_ClassName(): string {return 'home_activity_setting';}}
export { home_activity_setting };
创建完成之后，记得要在开发工具中把数据提交到云端，我们把数据提交到云端后，可以看到数据提交成功并且表也已经创建完成
进行数据查询 let databaseZone = cloudDatabase.zone('default');let condition3 = new cloudDatabase.DatabaseQuery(home_activity_setting);
let listData3 = await databaseZone.query(condition3);let json3 = JSON.stringify(listData3)let data3:HomeActivitySetting[]= JSON.parse(json3)this.homeActivity=data3} catch (err) {hilog.error(0x0000, 'testTag', Failed to query data, code: ${err.code}, message: ${err.message});
}
数据也已经查询成功，接下来我们直接运行程序，可以看到金刚区是在显示中的，接下来我们修改金刚区的状态，再执行一下，可以看到金刚区已经不见了，到这里我们首页模块的显示隐藏配置已经实现了。
