我已经能够使用调用处理上传的函数的自定义字段模板成功上传图像。然后它收集返回 url 并从那里，我不知道如何将其插入到字段中以与表单一起保存。
任何帮助将非常感激 ：）
这是我的代码：
var myApp = angular.module('myApp', ['ng-admin', 'backand', 'ngFileUpload']);
//myApp.directive('dashboardSummary', require('./dashboards/dashboardSummary'));
myApp.config(['BackandProvider', function(BackandProvider) {
BackandProvider.setAppName('');
BackandProvider.setSignUpToken('');
BackandProvider.setAnonymousToken('');
}]);
myApp.config(function(RestangularProvider) {
// add a response interceptor
RestangularProvider.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
var extractedData;
// .. to look for getList operations
if (operation === "getList") {
// .. and handle the data and meta data
extractedData = data.data;
extractedData.meta = data.data.__metadata;
} else {
extractedData = data;
}
return extractedData;
});
});
myApp.config(['NgAdminConfigurationProvider','BackandProvider', function (nga, BackandProvider, $scope) {
// create an admin application
BackandProvider.setAppName('');
BackandProvider.setSignUpToken('');
BackandProvider.setAnonymousToken('');
