mapping

问题 I have a google sheet that has project data(project code, name, dates project leaders et.c) and I am trying to get row data for unique values in this case emails. If for example email johndoe@testmail.com appear x number of times, the row data should be captured and passed to html file then emailed to johndoe@testmail.com same case to other emails. So specific project leaders should receive emails on only the projects they lead. I have am newbie in JavaScript/GAs, and have done tonnes of

问题 Dynamic templates allow you to define custom mappings that can be applied to dynamically added fields based on: the datatype detected by Elasticsearch, with match_mapping_type. the name of the field, with match and unmatch or match_pattern. the full dotted path to the field, with path_match and path_unmatch. I was trying to have a default type keyword for all fields while some special fields with specific *Suffix or prefix* could have specified types as follows, but it turned out all fields

问题 This is my first question here, so please let me know if there's anything I can provide to make my question clearer. Thanks! Is there anyway to tweak MyBatis (3.0.4) so that when it's running through the nested result maps and creating objects based on the results, it doesn't create "duplicate" objects and instead references the object that has already been created? To clarify, let's say I've got an object that consists of the following (simplified) info: Public class PrimaryObject { Private

问题 I've got this function: fn folders(dir: &Path) -> Result<Vec<PathBuf>, io::Error> { fs::read_dir(dir)? .into_iter() .map(|x| x.map(|entry| entry.path())) .collect() } It's actually borrowed from here. The function is OK; unfortunately, I don't really understand how it works. Ok(["/home/ey/dir-src/9", "/home/ey/dir-src/11", "/home/ey/dir-src/03 A Letter of Explanation.mp3", "/home/ey/dir-src/02 Egyptian Avenue.mp3", "/home/ey/dir-src/alfa", "/home/ey/dir-src/10"]) The test output shows both

问题 The following program tries to grade the marks of a student: use std::io; fn main() { let mut in0 = String::new(); io::stdin().read_line(&mut in0).expect("stdin err"); let n: i32 = in0.trim().parse().expect("parse err"); println!("{}", n); let mut v: Vec<i32> = Vec::new(); for _ in 0..n { let mut inp = String::new(); io::stdin().read_line(&mut inp).expect("stdin err"); let num: i32 = inp.trim().parse().unwrap(); v.push(num); } let out: Vec<_> = v .iter() .map(|x| { if x < 38 { x } else if x %

问题 I'm wondering about methods of mapping multiple arrays into one list of object. I mean e.g. I have val a = arrayOf("A1","A2","A3") val b = arrayOf("B1","B2","B3") and data class SomeClass(val v1:String, val v2:String) I want to parse it in elegant way to have list like that: val list = listOf(SomeClass("A1","B1"),SomeClass("A2","B2"),SomeClass("A3","B3")) I assume they are of the same length. The only way I thought of is: val list = mutableListOf<SomeClass>() for (i in a.indices) array.add

问题 I have the following Python code: data = ['1', '4.6', 'txt'] funcs = [int, float, str] How to call every function with data in corresponding index as an argument to the function? Now I'm using the code: result = [] for i, func in enumerate(funcs): result.append(func(data[i])) map(funcs, data) don't work with lists of functions ( Is there builtin function to do that simpler? 回答1: You could use zip* to combine many sequences together: zip([a,b,c,...], [x,y,z,...]) == [(a,x), (b,y), (c,z), ...]

问题 I'm trying to use AutoMapper for nodejs from nartc/automapper lib inside a NestJS project, but I'm having troubles when trying to use Profiles functionality. Here is my configuration: App.module @Module({ imports: [ AutomapperModule.withMapper(), ], controllers: [], providers: [], }) export class AppModule implements NestModule {} Profile @Profile() export class RoleProfile extends ProfileBase { constructor(@InjectMapper() mapper: AutoMapper) { super(); mapper .createMap(Role,

问题 While other questions have tackled the broader category of sequences and modules, I ask this very specific question: "What naming convention do you use for dictionaries and why?" Some naming convention samples I have been considering: # 'value' is the data type stored in the map, while 'key' is the type of key value_for_key={key1:value1, key2,value2} value_key={key1:value1, key2,value2} v_value_k_key={key1:value1, key2,value2} Don't bother answering the 'why' with "because my work tells me to
