角色管理 ​

渲染角色数据 ​

1、前端表格占位 ​

html

<div style="padding: 16px">
    <div class="layui-card">
        <div class="layui-card-body">
            <table
                    class="layui-hide"
                    id="role-table"
                    lay-filter="role-table"
            ></table>
        </div>
    </div>
</div>

2、请求接口数据 ​

javascript
table.render({
    elem: "#role-table",
    id: "role-table",
    url: "/api/v1/role",
    height: "full-35",
    toolbar: "#role-toolbar",
    page: true,
    cols: [
        [
            //标题栏
            {field: "id", title: "ID", width: 80, sort: true},
            {field: "name", title: "用户名", width: 120},
            {field: "code", title: "用户标识", width: 160},
            {field: "desc", title: "描述", maxWidth: 120},
            {field: "ids", title: "权限列表", width: 100},
            {
                fixed: "right",
                title: "操作",
                width: 180,
                align: "center",
                toolbar: "#role-tool",
            },
        ],
    ],
});

3、后端返回用户数据 ​

python
@role_api.get("/role")
def role_list():
    page = request.args.get("page", default=1, type=int)
    per_page = request.args.get("limit", default=10, type=int)
    q = db.select(RoleORM)

    pages: Pagination = db.paginate(q, page=page, per_page=per_page)

    return {
        "code": 0,
        "msg": "获取角色数据成功",
        "data": [item.json() for item in pages.items],
        "count": pages.total,
    }

新增角色 ​

1、新增表格头标签 ​

html

<script type="text/html" id="role-toolbar">
    <div class="layui-btn-container">
        <button class="layui-btn layui-btn-sm" lay-event="role-toolbar-add">
            新增角色
        </button>
    </div>
</script>

2、处理新增事件 ​

javascript
table.on("toolbar(role-table)", function (obj) {
    if (obj.event === "role-toolbar-add") {
        layer.open({
            type: 1,
            shade: false,
            content: $("#role-form"),
            area: ["50%", "80%"],
        });
        form.render($("#role-form"));
    }
});

3、新增表单 ​

html

<form
        class="layui-form"
        lay-filter="role-form"
        id="role-form"
        action=""
        style="padding: 15px; display: none"
>
    <div class="layui-form-item">
        <label class="layui-form-label">ID</label>
        <div class="layui-input-block">
            <input
                    type="text"
                    name="id"
                    value="0"
                    lay-verify="required"
                    autocomplete="off"
                    class="layui-input"
                    disabled
            />
        </div>
    </div>
    <div class="layui-form-item">
        <label class="layui-form-label">用户名</label>
        <div class="layui-input-block">
            <input
                    type="text"
                    name="name"
                    placeholder="请输入用户名"
                    lay-verify="required"
                    autocomplete="off"
                    class="layui-input"
            />
        </div>
    </div>
    <div class="layui-form-item">
        <label class="layui-form-label">标识</label>
        <div class="layui-input-block">
            <input
                    type="text"
                    name="code"
                    placeholder="请输入用户标识"
                    lay-verify="required"
                    autocomplete="off"
                    class="layui-input"
            />
        </div>
    </div>
    <div class="layui-form-item">
        <label class="layui-form-label">描述</label>
        <div class="layui-input-block">
            <input
                    type="text"
                    name="desc"
                    placeholder="请输入用户描述"
                    autocomplete="off"
                    class="layui-input"
            />
        </div>
    </div>
    <div class="layui-form-item">
        <label class="layui-form-label">权限列表</label>
        <div class="layui-input-block">
            <input
                    type="text"
                    name="rights_ids"
                    placeholder="请输入用户权限列表"
                    autocomplete="off"
                    class="layui-input"
            />
        </div>
    </div>
    <div class="layui-form-item">
        <div class="layui-input-block">
            <button
                    type="submit"
                    class="layui-btn"
                    lay-submit
                    lay-filter="role-form-btn"
            >
                立即提交
            </button>
            <button type="reset" class="layui-btn layui-btn-primary">重置</button>
        </div>
    </div>
</form>

4、前端提交事件 ​

javascript
form.on("submit(role-form-btn)", function (data) {
    var field = data.field;
    let method, url;
    if (field.id == 0) {
        field.id = null;
        method = "POST";
        url = "/api/v1/role";
    } else {
        method = "PUT";
        url = `/api/v1/role/${field.id}`;
    }
    $.ajax({
        url: url,
        type: method,
        contentType: "application/json",
        data: JSON.stringify(field),
        success: function (res) {
            if (!res.code) {
                layer.closeAll();
                table.reloadData("role-table");
            }
        },
    });
    return false;
});

5、后端完成修改 ​

python
@role_api.post("/role")
def create_role():
    data = request.get_json()
    if data["id"]:
        del data["id"]
    role = RoleORM(**data)
    role.save()
    return {"code": 0, "msg": "新增角色成功"}

修改角色 ​

1、添加表格行编辑标签

html

<script type="text/html" id="role-tool">
    <div class="layui-btn-container">
        <button
                class="layui-btn layui-btn-sm layui-bg-blue"
                lay-event="role-tool-edit"
        >
            编辑
        </button>
        <button
                class="layui-btn layui-btn-sm layui-bg-yellow"
                lay-event="role-tool-detail"
        >
            授权
        </button>
        <button
                class="layui-btn layui-btn-sm layui-bg-red"
                lay-event="role-tool-del"
        >
            删除
        </button>
    </div>
</script>

2、处理表格行编辑事件 ​

javascript
table.on("tool(role-table)", function (obj) {
    if (obj.event === "role-tool-edit") {
        form.val("role-form", obj.data);
        layer.open({
            type: 1,
            shade: false,
            content: $("#role-form"),
            area: ["50%", "80%"],
        });
    }
});

3、处理提交事件 ​

与新增共用同一个事件

4、后端完成修改 ​

python
@role_api.put("/role/<int:rid>")
def change_role(rid):
    data = request.get_json()
    del data["id"]

    role_obj = RoleORM.query.get(rid)
    for key, value in data.items():
        setattr(role_obj, key, value)
    role_obj.save()
    return {"code": 0, "msg": "修改角色权限成功"}

删除角色 ​

1、前端部分 ​

javascript
table.on("tool(role-table)", function (obj) {
    if (obj.event === "role-tool-edit") {
        // ...
    } else if (obj.event === "role-tool-del") {
        $.ajax({
            url: `/api/v1/role/${obj.data.id}`,
            type: "DELETE",
            contentType: "application/json",
            success: function (res) {
                if (!res.code) {
                    table.reloadData("role-table");
                }
            },
        });
    } 
});

2、后端完成删除 ​

python
@role_api.delete("/role/<int:rid>")
def del_role(rid):
    role_obj = RoleORM.query.get(rid)
    role_obj.delete()
    return {"code": 0, "msg": "删除角色成功"}
