nested

问题 I'm trying to create nested JSON object by combining more than one relational tables using python/pandas. I'm a beginner in Python/pandas, so looking for bit of a help here... In the following example, instead of tables, I'm using CSV files just to keep it simple Table1.csv Emp_id, Gender, Age 1, M, 32 2, M, 35 3, F, 31 Table2.csv Emp_id, Month, Incentive 1, Aug, 3000 1, Sep, 3500 1, Oct, 2000 2, Aug, 1500 3, Aug, 5000 3, Sep, 2400 I want to create a JSON object like below *Required output: {

问题 I would like to make a sort of directory structure with Ember.js. Here is an example of how an url can look like: folder/1/folder/44/document/3 As you can see a folder can have multiple folders inside but also documents. I'm wondering how I should handle something like this in my router because beforehand my application doesn't know if a folder has other folders inside or only documents. I think I need to make separated routes instead of nested routes: App.Router.map(function() { this.route(

问题 I have kind of a tricky Oracle problem. I am trying to select one set of data, we'll call items. For each item I want to call another procedure and return an Inventory Item. I have two operations I am not sure on how to perform. How do I retrieve a value from the nested procedure? How do I return those retrieved values in the form of SYS_REFCURSOR? My attempt here was to put the results from spSelect_Inv_Search into a nested table called ITEMS_TABLE. This is not working. Code below PROCEDURE

问题 I am constructing a task app ( For fun) & i just sat down thinking about this problem. I will put the question on my mind in words here. Model is extremely simple, it contains collection of Project . Each Project contains a TaskList these TaskList is nestable i.e for example a Task Design FrontPage can have Design Header as another TaskList . Each TaskList contain Tasks . How will a typical javascript template look like for this problem. I could not come with one that works this scenario.

问题 Whenever I use a directive within itself, the page freezes, and eats up more and more CPU and RAM until the tab hangs. What I have is this Application.Directives.directive('somed', function() { return { restrict: 'E', // Load the template from a separate HTML file templateUrl: 'directives/somed/view.html', replace: true }; }); and template like <div ng-if="nonexistent"> <somed></somed> </div> Which should never load the nested directive (the ng-if evaluates to false, so no content is shown.

问题 I have an XML that looks like this <executionPlan name="Test" > <paramList> <param name="param1" default=""/> </paramList> <varList> <var name="bla" default=":[param1]"/> </varList> <simpleSteps limitToHostSet="bla"> <execNative> <exec cmd="/bin/sh"/> </execNative> </simpleSteps> and I need to transform it to look like this: <executionPlan name="Test" > <paramList> <param name="param1" default=""/> </paramList> <simpleSteps limitToHostSet="bla"> <varList> <var name="bla" default=":[param1]"/>

问题 So I am aware that braces in code can mean more than just an initializer_list : What Is a Curly-Brace Enclosed List If Not an intializer_list? But what should they default to? For example, say that I define an overloaded function: void foo(const initializer_list<int>& row_vector) { cout << size(row_vector) << "x1 - FIRST\n"; } void foo(const initializer_list<initializer_list<int>>& matrix) { cout << size(matrix) << 'x' << size(*begin(matrix)) << " - SECOND\n"; } If I call foo({ 1, 2, 3 }) the

问题 I would like to keep the code readable by writing the actual code of a nested class outside the main class, Is it possible, and how ? class AA{ //random code class BB : public CC <double> { // very long code }; // random code }; I would like to write something like : class AA{ //random code //<declaration of class BB> // random code }; class BB : public CC <double>{ // very long code }; and the BB class should only be accessible within the AA class... 回答1: class A { class B; }; class A::B { /

问题 I am trying to implement inner hits with elasticsearch using Java API, but I cannot find much of any documentation on it or examples that other people are using. I have my JSON search that works as follows: { "query": { "filtered": { "query": { "match_all": {} }, "filter": { "nested": { "path": "locations", "filter": { "geo_distance": { "distance": "20km", "locations.address.geoLocation": { "lat": 38.07061, "lon": -76.77514 } } }, "inner_hits": {} } } } } } I see an InnerHitsBuilder and
