如何让ng-admin过滤器与环回API一起工作

Question

我是ng-admin和angularjs的新手。我正在尝试将ng管理与管理面板的环回集成。

我无法使ng筛选器筛选器与环回一起工作因此，我认为referencelist和其他过滤器不能正常工作。

问题是我无法在对api的请求中包含where过滤器我正在尝试使用restangular

下面是代码

// custom filters
if (params._filters) {
    for (var filter in params._filters) {
        params['filter[where]'] = "{" + entry.field + ":"  + rams._filters[filter] + "}";
    }
    delete params._filters;
}

Answer 1

对于"where"过滤器可以是这样的：

for(var entry in params._filters) {
  if (params._filters[entry] !== undefined) {
    if (params._filters[entry].constructor === Array && params._filters[entry].length > 1) { // where value in array of values
      params['filter[where][' + entry + '][inq]'] = params._filters[entry];
    }
    else {  // where entry = value
      params['filter[where][' + entry + ']'] = params._filters[entry];
    }
  }
}

Answer 2

这是我的整个拦截器，用于使用环回处理分页、排序和过滤。希望这能节省一些时间。请注意，以"id"结尾的关系字段上的筛选器使用相等处理，而其他字段上的过滤器使用"like"。

myApp.config(['RestangularProvider', function (RestangularProvider) {
    RestangularProvider.addFullRequestInterceptor(function(element, operation, what, url, headers, params) {
        if (operation == "getList") {
            // custom pagination params
            if (params._page) {
                params["filter[skip]"]= (params._page - 1) * params._perPage;
                params["filter[limit]"] = params._perPage;
            }
            delete params._page;
            delete params._perPage;
            // custom sort params
            if (params._sortField) {
                params["filter[order]"] = params._sortField + " " + (params._sortDir || 'ASC');
                delete params._sortField;
                delete params._sortDir;
            }
            // custom filters
            if (params._filters) {
                var filterClause = "";
                var i = 0;
                for (var filter in params._filters) {
                    if (filter.endsWith('id')) {
                        params["filter[where][and][" + i + "][" + filter + "]"] = params._filters[filter];
                    } else {
                        params["filter[where][and][" + i + "][" + filter + "][like]"] = '%' + params._filters[filter] + '%';
                    }
                    i++;
                }
                delete params._filters;
            }
        }
        return { params: params };
    });
}]);
