nested

问题 I found out the same problem in internet, but i dont understand a solution. The problem is, how can i update a nestend document without to update all array. Thank you so much. Here is a nasted document "links": [ [ { "note_link_id": "1", "user_id": "11", "creation": "2016-11-15T11:21:10", "modification": "2016-11-15T13:38:04", "to_asset": "100", "from_asset": "99", "comment": "Comment 1." }, { "note_link_id": "2", "user_id": "11", "creation": "2016-11-15T13:37:04", "modification": "2016-11

问题 According to this question/answer in stackoverflow, it is not possible to directly rewrite C++ nested typedefs in cython. I have such a problem and I don't know which is the right/optimal way to proceed. Let me be more specific with an example. Below, you can find the content of two C++ files (one header.h and one .cpp) and of two corresponding cython files (one .pxd and one .pyx). In the C++ header file called cpp_graph.h you can see nested typedef declarations; for example, that

问题 Is there a way for PCRE regular expressions to count how many occurrences of a character it encounters (n), and to stop searching after it has found n occurrences of another character (specifically { and } ). This is to grab code blocks (which may or may not have code blocks nested inside them). If it makes it simpler, the input will be a single-line string, with the only characters other than braces are digits, colons and commas. The input must pass the following criteria before code blocks

问题 Here is my table (simplified, only significant columns): CREATE TABLE things ( id serial primary key , name varchar , blueprint json default '{}' ); And some sample data: # select * from things; id | name | blueprint ----+---------+----------------------------------------------------------------------------- 1 | Thing 1 | {} 2 | Thing 2 | {"1":{"name":"Iskapola","wight":"2"}} 3 | Thing 3 | {"1":{"name":"Azamund","weight":"3"}, "2":{"name":"Iskapola","weight":"1"}} 4 | Thing 4 | {"1":{"name":

问题 I think I want to make a 2D dictionary with multiple keys per value. I know how to make a 2D dictionary using defaultdict : from collections import defaultdict 2d_dict = defaultdict(dict) 2d_dict['canned_food']['spam'] = 'delicious' And I know that using regular dictionaries you can make with multiple keys like: dictionary={('food','canned_food'):spam} But I want to do something like lookup by tuple-of-keys: 2d_dict[('canned_food','food')]['spam'] = 'delicious' In the first dimension of

问题 In JUnit 5, there is a new annotation: @Nested . I understand how it work, I understand why we use nested class, I just don't understand why we need to have nested test class in our test. 回答1: The @Nested annotation allows you to have an inner class that's essentially a test class, allowing you to group several test classes under the same parent (with the same initialization). 回答2: All my tests need a database server running. Most of my tests also need a Users table in the database, to be

问题 I was working on a cool project I am doing in Python and I needed a way to do this without recursion because this would limit the size it could be by limiting the amount of times the loop could go through it (max recursion depth). The function needs to work on a nest dictionary of any size. How can I add entries, and retrieve, alter, or remove values from specific keys in any nested dictionary? I haven't found a good answer for this on SO because they all are either overly complex or use
