我可以设置CRUD Controller来根据编辑的模型来显示字段吗？
示例：我的模型具有以下字段：id，type，field1，field2。
对于带有type=type1的模型，我只想显示field1：
$this->crud->addFields([
['name' => 'field1', 'label' => 'field1 label']
]);
对于仅具有type=type2 field2的模型：
$this->crud->addFields([
['name' => 'field2', 'label' => 'field2 label']
]);
对于同时具有type=type3和field1的{{1}}的模型：
field2答案 0 :(得分：1)
在this page in the docs的最底部列出：
在自定义字段类型中，您可以使用以下变量：
...
$ entry-在“更新”操作中，当前条目被修改（实际值）；
一种实现此目的的方法是使用自定义字段并利用该export class CompanyInvoicesComponent implements OnInit {
public isLoading: boolean;
public limit = 10;
public temp = [];
public selected = [];
public invoice: Invoice;
public statusFilter: number = 0;
public rows: Invoice[];
@ViewChild(DatatableComponent) table: DatatableComponent;
constructor(
private _appService: AppService,
private _invoiceService: InvoiceService,
) {
this._invoiceService.companyInvoices()
.subscribe( (invoices) => {
const invoicesArr = [];
for (const invoice of invoices) {
invoicesArr.push(new Invoice(invoice, true));
}
this.rows = invoicesArr;
this.temp = [...invoicesArr];
this._appService.toggleLoading(false);
});
}
updateFilter(event) {
const val = event.target.value.toLowerCase();
let temp = this.temp.filter((invoice) => {
// the type number is lost after value is changed.
const parsedStatusFilter = parseInt(this.statusFilter.toString(), 10);
console.log(parsedStatusFilter);
if (parsedStatusFilter == 0) {
return (invoice.name.toLowerCase().indexOf(val) !== -1 || !val);
} else {
return (parsedStatusFilter == invoice.statusNumber) && (invoice.name.toLowerCase().indexOf(val) !== -1 || !val);
}
});
// update the rows
this.rows = temp;
// Whenever the filter changes, always go back to the first page
this.table.offset = 0;
}
变量。例如，您可以创建2个这样的自定义字段：
field1.blade.php
$entryfield2.blade.php
@if(in_array($entry->type, ['type1','type3']))
{{-- your field content here, see resources/views/vendor/backpack/crud/fields/text.blade.php as an example --}}
@endif
然后，在您的控制器中，您总是要添加两个字段，并让这些字段自己进行隐藏适当字段的工作。
@if(in_array($entry->type, ['type2','type3']))
{{-- you can even pull in the content of an existing field like this --}}
@include('crud::fields.text')
@endif
