nested

问题 this is a follow-up to this question I had here. I can now POST a new AP object using user Primary Key and after commenting this line in the AP serializer user = UserIndexSerializer() : Postman request: { "user":1, "name":"Max AP 05" } However the problem that I now have is that the initial UserIdexSerializer is rendered useless. This serializer determines the fields to show in a GET request but in consequence imposes the fields required in a POST request. What I'm trying to do is: POST a new

问题 I want to measure a "nesting level" of a method using Roslyn, for example: if the method contains only one expression its level is 0. If the method contains nested if(cond1) if(cond2) its level is 1. I try to use Roslyn's nodes, but I don't understand how to get only the body of the while or the if construction without it's condition and other things. 回答1: You can use SyntaxVisitor for this: it recursively walks the syntax tree and executes your code for each node, depending on its type. You

问题 I am trying to develop a program that shuffles a deck by dividing the deck into two and then interlacing them. Class Deck represents a deck of 52 cards. There are two methods: Deck(int n) and Card drawCard() . Deck(int n) is the constructor. The parameter tells how many rounds the deck should be shuffled. In each round of shuffling, the whole deck is first divided into two sub-decks. The sub-decks are then interlaced into one whole deck. Some notes : To simplify the discussion, we assume the

问题 Given a list, I can get the product of each item in a list as such: from itertools import product x = 'apple orange pair None'.split() [i + ' ' + j for i, j in product(x, x)] [out]: ['apple apple', 'apple orange', 'apple pair', 'apple None', 'orange apple', 'orange orange', 'orange pair', 'orange None', 'pair apple', 'pair orange', 'pair pair', 'pair None', 'None apple', 'None orange', 'None pair', 'None None'] If I want to nest the output of product(list, list) with the initial list, I could

问题 Im trying to find the right way of allocation memory for the following structure. struct part1 { char* c1; char* c2; } struct part2 { int a; struct part1 *local; } struct response { struct part1* p1; struct part2* p2; } This is what I do, as gathered from the documents. int myservice ( soap *soap, struct request *request, struct response *resp) { ... // top level resp is setup by soap_serve resp->p1 = soap_new_ns__part1(soap,1); resp->p1->c1 = soap_new_string(soap,10); (also tried soap_malloc

问题 I have the following nested struct definition: typedef struct { int count; float cash; char item[50];//switch between array and pointer for testing initializers //char *item; }Purchase; typedef struct { int accnt; char acct_name[50]; Purchase purch; } Acct; Where for the Purchase struct by itself, the following initializer works: //Uses member names: /* 1 */Purchase p = {.count = 4, .cash = 12.56, .item = "thing"}; // Note: this member: ^^^^^^^^^^^^^^^ And for the nested struct Acct the
