nested

问题 Consider the scenario where you have a collection, and inside that collection are particular objects. Those objects also hold a collection, and inside those collections are more of the same objects. It's a nested collection with many layers. List<WorkItemClassificationNode> items; List<WorkItemClassificationNode> subItems = items.Children; List<WorkItemClassificationNode> subSubItems = subItems.Children; // etc I just want a method to iterate through each of those layers so the same logic is

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 11 months ago . Improve this question I know using recursions way but it works just for loops which beginning and ending statements are same like code below for (int i=1 ; i<5;i++){ for (int j=0; j<5;j++){ for (int m= 0;m<5;m++) { // N time } } } But my problem is different. I do not know N level and beginning

问题 I am going to update some fields of mongoose document according to provided keys. For example, When we present mongoose document in json. user: { address: { city: "city" country: "country" } } And update params is given like this. address: { city: "city_new" } when I run the mongoose api like this. let params = { address: { city: "city_new" } } User.set(param) It replace whole address object and final result is user: { address: { city: "city_new" } } it just replace address field, but I want

问题 Being rather new to LINQ, I am probably not looking for the correct search terms, that's why I am asking here. I have a data transfer object (DTO) for the current timestep and a DTO for the previous timestep. I am intending to JOIN this information into a single (nested) list and display procentual changes (for all entries of the list). The nested contains nodes of type myObject . In other words, the list consists of a couple of parent entries and (different levels of) child elements of the

问题 OK, I've not been able to figure this out thus far. Hoping someone can offer some insight. Given the documents below, how would I search for all documents with a video that has "test" in the video title? I'm using the HTTP API. (Basically, how do you search nested objects with elastic search? I know there has to be docs out there, but I haven't really been able to find any.) [{ id:4635, description:"This is a test description", author:"John", author_id:51421, video: { title:"This is a test

问题 Working in python, my goal is to parse through an XML doc I made and create a nested list of lists in order to access them later and parse the feeds. The XML doc resembles the following snippet: <?xml version="1.0'> <sources> <!--Source List by Institution--> <sourceList source="cbc"> <f>http://rss.cbc.ca/lineup/topstories.xml</f> </sourceList> <sourceList source="bbc"> <f>http://feeds.bbci.co.uk/news/rss.xml</f> <f>http://feeds.bbci.co.uk/news/world/rss.xml</f> <f>http://feeds.bbci.co.uk

问题 So I'm using a nested list to store some data and I'm having trouble with changing specific values of one of the sublists: if attributes[3] == 'W': self.board[3][3] = 'W' (numbers are placeholders i'm using to test) board is a class variable that is created as follows (I'm trying to create a grid as specified by a user, with their input for column and row sizes making up the first two parts of attributes) self.board = [] rows = [] self.score = [0, 0] for x in range(attributes[0]): rows.append

问题 I'm playing a bit with terraform state json output and want to transform it a bit. Given that input issued from terraform: { "cost": { "sensitive": false, "value": "123" }, "test_id": { "sensitive": false, "value": "6610758455459338306" } } How do i convert it to something usefull for my application like bellow: { "cost": "123", "test_id": "6610758455459338306" } I tried to play with from_entries , with_entries but i'm a complete noob at it 回答1: You're looking for map_values. It works just

问题 I'm starting my journey with Vue.js, and stumbled upon some problem. I wanted to create a simple sidebar with dropdown menu, and already got this: new Vue({ el: '#app', data() { return { openedItems: {}, selectedSub: '', userMenu: false, items: [{ icon: './src/assets/img/icons/dashboard.svg', text: 'Element 1', path: '#1' }, { icon: './src/assets/img/icons/orders.svg', text: 'Element 2', path: '#2' }, { icon: './src/assets/img/icons/products.svg', text: 'NestedElement', path: '', children: [{
