如何解决Angular - 如何在@tusharghoshbd ngx-datatable
我在 Angular-12 中有一个项目,我正在使用 @tusharghoshbd ngx-datatable 来显示日期。
我有三个表:用户、公司和角色。一个用户可以拥有多个角色,但只能属于一个公司。用户是主表
我在 API JSON GET 请求中对此进行了整理,如下所示:
{
"message": "You have successfully Retrieved User Detail","error": false,"code": 200,"results": {
"user": {
"id": 2,"company_id": 6,"first_name": "Ashar","email": "example@email.com","last_name": "Nelo","roles": [{
"id": 4,"name": "HOD","guard_name": "api"
},{
"id": 6,"name": "Account Officer","guard_name": "api"
}
],"company": {
"id": 6,"name": "ABC Company","website": "https://mycompany.com",}
},}
}
现在我尝试使用@tusharghoshbd ngx-datatable 在 Angular 中显示它
组件:
export class SiteInfoComponent implements OnInit {
@ViewChild('actionTpl',{
static: true
}) actionTpl: TemplateRef < any > ;
@ViewChild('addresstpl',{
static: true
}) addresstpl: TemplateRef < any > ;
isLoading: boolean = false;
options: any = {};
userInfoList: any[] = [];
columns: any = {};
constructor(private userInfoService: SUserInfoService) {}
ngOnInit(): void {
this.isLoading = true;
this.userInfoService.getAllUserDetail().subscribe(
data => {
this.userInfoList = data.results.users;
console.log(data);
},error => {
this.isLoading = false;
}
);
this.options = {
loader: true
};
this.columns = [{
key: 'id',title: '<div class="blue"><i class="fa fa-id-card-o"></i> ID</div>',width: 60,sorting: true,align: {
head: 'center',body: 'center'
},vAlign: {
head: 'bottom',body: 'middle'
}
},{
key: 'first_name',title: '<div class="blue"><i class="fa fa-user"></i> First Name</div>',width: 100
},{
key: 'last_name',title: '<div class="blue"><i class="fa fa-user"></i> Last Name</div>',{
key: 'email',title: '<div class="blue"><i class="fa fa-phone"></i> Email</div>',align: {
head: 'left'
},width: 100,sorting: true
},{
key: '',title: '<div class="blue">Action</div>',sorting: false,width: 80,cellTemplate: this.actionTpl
}
];
}
edit(row: any) {}
remove(rowIndex: any) {}
}
html:
<ngx-datatable tableClass="table table-striped table-bordered table-hover" [data]="userInfoList" [columns]="columns" [options]="options">
<ngx-caption>
<div class="row">
<div class="col-sm-6 col-xs-6 col-6 ">
<b>
<i class="fa fa-table" aria-hidden="true"></i>
Site Info. List
</b>
</div>
<div class="col-sm-6 col-xs-6 col-6 text-right">
<button type="button" class="btn btn-primary">
<i class="fa fa-plus" aria-hidden="true"></i> Add New Data
</button>
</div>
</div>
</ngx-caption>
<ng-template #addresstpl let-row let-rowIndex="rowIndex" let-columnValue="columnValue">
{{columnValue.name}},{{columnValue.email}}
</ng-template>
<ng-template #actionTpl let-row let-rowIndex="rowIndex" let-columnValue="columnValue">
<a href="javascript:void(0)" (click)="edit(row)">Edit</a> |
<a href="javascript:void(0)" (click)="remove(rowIndex)">Delete</a>
</ng-template>
</ngx-datatable>
这些工作正常。但在 @tusharghoshbd ngx-datatable 中, 我想包括公司和角色的相关字段。每个角色中的名称,以及 API 中显示的公司名称。
我如何实现这一目标?
谢谢
解决方法
问题和关注
想说明您正在访问 data.results.users
,这对于您的 JSON 结果无效。
this.userInfoList = data.results.users;
{
"message": "You have successfully Retrieved User Detail","error": false,"code": 200,"results": {
"user": {
...
},}
}
与此同时,因为您的 JSON 返回单个对象而不是数组。
问题解决方案:将单个对象转换为数组
site-info.component.ts
this.userInfoList = [data.results.user];
问题的解决方案
要显示每个角色的公司名称和名称,您可以使用 cellTemplate
。
site-info.component.html
<ngx-datatable tableClass="table table-striped table-bordered table-hover" [data]="userInfoList" [columns]="columns"
[options]="options">
...
<ng-template #companyTpl let-row let-rowIndex="rowIndex" let-columnValue="columnValue">
{{columnValue.name}}
</ng-template>
<ng-template #rolesTpl let-row let-rowIndex="rowIndex" let-columnValue="columnValue">
<ng-template ngFor let-obj [ngForOf]="columnValue">
{{obj.name}}
<br />
</ng-template>
</ng-template>
</ngx-datatable>
site-info.component.ts
export class SiteInfoComponent implements OnInit {
...
@ViewChild('companyTpl',{
static: true
})
companyTpl: TemplateRef<any>;
@ViewChild('rolesTpl',{
static: true
})
rolesTpl: TemplateRef<any>;
...
ngOnInit(): void {
...
this.columns = [
...
{
key: 'company',title: '<div class="blue">Company</div>',align: {
head: 'left'
},width: 100,sorting: true,cellTemplate: this.companyTpl
},{
key: 'roles',title: '<div class="blue">Roles</div>',cellTemplate: this.rolesTpl
},...
];
this.userInfoService.getAllUserDetail().subscribe(
data => {
this.userInfoList = [data.results.user];
console.log(data);
},error => {
this.isLoading = false;
}
);
}
}
