通过上一篇文章 基于Vue和Quasar的前端SPA项目实战之序列号(四)的介绍,我们已经完成了元数据中序列号的增删改查,本文主要介绍动态表单设计功能的实现。
在crudapi系统中,所有的业务表单都是通过配置动态生成的,代码无需写死,有关基本概念参考之前文章 元数据管理—动态表单设计器在crudapi系统中完整实现 ,表单配置好之后,对应的crud接口就自动生成了。
表单列表
创建表单
索引管理
表单API包括基本的CRUD操作,具体的通过swagger文档可以查看。通过axios封装api,名称为metadataTable
import { axiosInstance } from "boot/axios"; const metadataTable = { create: function(data) { return axiosInstance.post("/api/metadata/tables", data ); }, update: function(id, data) { return axiosInstance.patch("/api/metadata/tables/" + id, data ); }, list: function(page, rowsPerPage, search, query) { if (!page) { page = 1 } if (!rowsPerPage) { rowsPerPage = 10 } return axiosInstance.get("/api/metadata/tables", { params: { offset: (page - 1) * rowsPerPage, limit: rowsPerPage, search: search, ...query } //permission: ["ROLE_META_TABLE_R"] } ); }, count: function(search, query) { return axiosInstance.get("/api/metadata/tables/count", { params: { search: search, ...query } } ); }, get: function(id) { return axiosInstance.get("/api/metadata/tables/" + id, { params: { } } ); }, getByName: function(name) { return axiosInstance.get("/api/metadata/tables/name/" + name, { params: { } } ); }, delete: function(id) { return axiosInstance.delete("/api/metadata/tables/" + id); }, batchDelete: function(ids) { return axiosInstance.delete("/api/metadata/tables", {data: ids} ); } }; export { metadataTable };
表单设计页面用到了q-table控件,每一个字段对应一个行,
<q-table :data="table.columns" :columns="columns" :visible-columns="visibleColumns" :pagination.sync="tablePagination" row-key="id" selection="multiple" :selected.sync="selected" :loading="loading" flat separator="cell" hide-bottom> </q-table>
columns定义了q-table的列属性,涵盖表单的全部属性,比如名称,是否为一,数据类型,长度等。
columns: [ { name: "dataClickAction", align: "center", label: "操作", field: "dataClickAction", sortable: false }, { name: "displayOrder", align: "left", label: "顺序", field: "displayOrder", sortable: false }, { name: "caption", align: "left", label: "中文名称", field: "caption", sortable: false }, { name: "name", align: "left", label: "英文字段", field: "name", sortable: false }, { name: "description", align: "left", label: "描述", field: "description", sortable: false }, { name: "unsigned", align: "left", label: "无符号", field: "unsigned", sortable: false }, { name: "dataType", align: "left", label: "数据类型", field: "dataType", sortable: false }, { name: "indexType", align: "left", label: "索引类型", field: "indexType", sortable: false }, { name: "indexStorage", align: "left", label: "索引存储", field: "indexStorage", sortable: false }, { name: "indexName", align: "left", label: "索引名称", field: "indexName", sortable: false }, { name: "length", align: "left", label: "长度", field: "length", sortable: false }, { name: "precision", align: "left", label: "精度", field: "precision", sortable: false }, { name: "scale", align: "left", label: "小数", field: "scale", sortable: false }, { name: "autoIncrement", align: "left", label: "自增长", field: "autoIncrement", sortable: false }, { name: "nullable", align: "left", label: "空", field: "nullable", sortable: false }, { name: "defaultValue", align: "left", label: "默认值", field: "defaultValue", sortable: false },{ name: "seqId", align: "left", label: "序列号", field: "seqId", sortable: false }, { name: "insertable", align: "left", label: "插入", field: "insertable", sortable: false }, { name: "updatable", align: "left", label: "编辑", field: "updatable", sortable: false }, { name: "queryable", align: "left", label: "查询", field: "queryable", sortable: false } ]
支持上移,下移,置顶,置底四种操作。
onTopClick: function(row) { const columns = this.table.columns; const index = columns.findIndex(t => t.id === row.id); if (index != 0){ columns.unshift(columns.splice(index, 1)[0]); } }, onUpClick: function(row) { const columns = this.table.columns; const index = columns.findIndex(t => t.id === row.id); if (index != 0){ columns[index] = columns.splice(index - 1, 1, columns[index])[0]; console.dir(columns); } }, onDownClick: function(row) { const columns = this.table.columns; const index = columns.findIndex(t => t.id === row.id); if (index != columns.length - 1){ columns[index] = columns.splice(index + 1, 1, columns[index])[0]; } }, onBottomClick: function(row) { const columns = this.table.columns; const index = columns.findIndex(t => t.id === row.id); if (index != columns.length - 1){ columns.push(columns.splice(index, 1)[0]); } }
通过列表页面,新建页面和编辑页面实现了动态表单基本的crud操作,其中编辑和新建页面类似,编辑页面除了可以设置单个字段的索引,还可以设置多个字段的联合索引,更多内容参考源码即可。
本文主要介绍了元数据中动态表单设计功能,支持常见的数据类型和索引,然后实现了动态表单的crud增删改查功能,下一篇文章会介绍元数据中表关系功能。
