问题 I am trying to convert a simple pandas dataframe into a nested JSON file based on the answer I found here: pandas groupby to nested json My grouped dataframe looks like this: firstname lastname orgname phone mobile email teamname members 1 0 John Doe Anon 916-555-1234 none john.doe@wildlife.net 1 Jane Doe Anon 916-555-4321 916-555-7890 jane.doe@wildlife.net 2 0 Mickey Moose Moosers 916-555-0000 916-555-1111 mickey.moose@wildlife.net 1 Minny Moose Moosers 916-555-2222 none minny.moose@wildlife

问题 Here's the code: namespace Namespace { struct L0 { enum SomeEnum { EnumVal }; struct L1 { friend void f(SomeEnum) { std::cout << "f()" << std::endl; } }; friend void g(SomeEnum) { std::cout << "g()" << std::endl; } }; } int main() { f(Namespace::L0::EnumVal); // error: f not defined g(Namespace::L0::EnumVal); // good } The idea here is to make the compiler find f() and g() through ADL. However, this code fails to compile with gcc or clang. The similar code seemed to compile fine under MSVC

问题 I have to query a nested object using Nest, however the query is built in dynamic way. Below is code that demonstrate using query on nested "books" in a static way QueryContainer qry; qry = new QueryStringQuery() { DefaultField = "name", DefaultOperator = Operator.And, Query = "salman" }; QueryContainer qry1 = null; qry1 = new RangeQuery() // used to search for range ( from , to) { Field = "modified", GreaterThanOrEqualTo = Convert.ToDateTime("21/12/2015").ToString("dd/MM/yyyy"), };

问题 I have a nested array tree, generated from a flat array with the following function : function convertToTree(array $flat, $idField = 'id', $parentIdField = 'parentId', $childNodesField = 'childNodes') { $indexed = array(); // first pass - get the array indexed by the primary id foreach ($flat as $row) { $indexed[$row[$idField]] = $row; $indexed[$row[$idField]][$childNodesField] = array(); } //second pass $root = null; foreach ($indexed as $id => $row) { $indexed[$row[$parentIdField]][

问题 Can we make a nested ng-grid. something like this, is it possible. here's plunker: http://plnkr.co/edit/hYuFfxLR38LA0clIkF48?p=preview I have also tried doing this using , templateUrl. any suggestions, modifications to plunker or links ? 回答1: Yep, that might be working, although it doesn't make much sense. First of all you have to supply some data to the parent grid so that at least one row is rendered. Then you have to tell the parent grid to us another rowHeight than the default 30px. Don't

问题 I have a 3rd party input component (a vuetify v-text-field). For reasons of validation i prefer to wrap this component in my own. my TextField.vue <template> <v-text-field :label="label" v-model="text" @input="onInput" @blur="onBlur" :error-messages="this.getErrors(this.validation, this.errors)" ></v-text-field> </template> <script> import VTextField from "vuetify/es5/components/VTextField"; import {vuelidateErrorsMixin} from '~/plugins/common.js'; export default { name: "TextField", props: [

问题 I have a data set like follows- [{ "allowedusers": ["paul@abc.com"], "id": "1" },{ "allowedusers": ["kmahera@abc.com","rbajaniya@abc.com"], "id": "2" },{ "allowedusers": ["whatever@abc.com","rbajaniya@abc.com"], "id": "3" }] and I have a Query like this - http://localhost:3030/flowz$limit=5&allowedusers[$in[]=rbajaniya@abc.com&$skip=0&$select[]=id&$select[]=alloweduser . But I am not getting all the objects that contain rbajaniya@abc.com . How can I craft my query to get this. I want to get

问题 Is there a way to group files with same suffix but with variant prefix. Example: -hero.model.ts -power.hero.model.ts -weapon.hero.model.ts -bullet.weapon.hero.model.ts This guide (https://blogs.msdn.microsoft.com/webdev/2018/02/07/file-nesting-in-solution-explorer/) says: fileSuffixToExtension: Use this type of rule to make file-vsdoc.js nest under file.js or pathSegment: Use this type of rule to make jquery.min.js nest under jquery.js I'm looking for the same thing but with prefix instead of

问题 I have an iterator that returns context managers. I want a pythonic with statement, that emulates the behaviour of several nested with statements, one for each context manager returned by the iterator. One could say, I want a generalisation of the (deprecated) contextlib.nested function. 回答1: From the docs: Developers that need to support nesting of a variable number of context managers can either use the warnings module to suppress the DeprecationWarning raised by [ contextlib.nested ] or

问题 I was looking for a way to read a csv file with an unknown number of columns into a nested dictionary. i.e. for input of the form file.csv: 1, 2, 3, 4 1, 6, 7, 8 9, 10, 11, 12 I want a dictionary of the form: {1:{2:{3:4}, 6:{7:8}}, 9:{10:{11:12}}} This is in order to allow O(1) search of a value in the csv file. Creating the dictionary can take a relatively long time, as in my application I only create it once, but search it millions of times. I also wanted an option to name the relevant
