问题 Can I use partial classes to create properties that points to an association property generated by the L2S designer. Also, will I be able to use the new property in queries? How can I achieve this? 回答1: Yes you can, but you have to apply the same attributes as the linq2sql generated property i.e. [Association(Name="Test_TestData", Storage="_TestDatas", ThisKey="SomeId", OtherKey="OtherId")] public System.Data.Linq.EntitySet<TestData> MyTestDatas { get { return this.TestDatas; } } TestDatas

问题 When I name the elements of a vector I use tag - value pairs like these: myvec <- c("name1" = 1, "name2" = 2, "name3" = 3) > myvec name1 name2 name3 1 2 3 When I create a vector containing the names and index this vector from inside the c()-function, it doesn't work. namevec <- c("name1", "name2", "name3") myvec <- c(namevec[1] = 1, namevec[2] = 2, namevec[3] = 3) Error: unexpected '=' in "myvec <- c(namevec[1] =" My Question now: Why is that? Why does it work if I write "name1" , but if I

问题 Quite often I use values between 0.0 and 1.0 to hold progress, or transparancy, or other things that can go from none to full . A percentage if you will. I don't want to call it a percentage because it is not expressed as a value from 0 to 100. To give my variables a clear name, I still would like to describe this kind of value. What would be an appropriate name, I still haven't found one after years. 回答1: That is called a normalized value. 来源： https://stackoverflow.com/questions/34515311/how

问题 I am using a LateX template for my PhD thesis which is available via this link: https://github.com/kks32/phd-thesis-template/blob/master/Classes/PhDThesisPSnPDF.cls I wish to include two abstracts for the request of the University. One with the name "Abstract" and one with the name "Lay Summary". But I am having trouble changing the title in the second abstract. The abstract is a tex file starting with the following lines: \begin{abstract} .... \end{abstract} The documentclass is a custom

问题 I have this feature file: Scenario Outline: Example Given I am a user When I enter <x> as an amount Then the result should be <result> Examples: | x | result | | 3 | 3 | | 1 | 1 | My issue is that after it's run, each example is labeled as variant # Is there a way to name what each example line is actually testing, so that in the report, we know better what is tested, not just: Scenario: Example, Variant 0 Scenario: Example, Variant 1 Scenario: Example, Variant 2 I'm trying to help our

问题 I tried creating a model called "class" (as in a graduating class of students), and encountered all kinds of problems. What are some other words or class names to avoid in Rails? Some links I've found: http://juicebar.wordpress.com/2007/05/30/reserved-words-in-rails/ http://railsforum.com/viewtopic.php?id=22242 回答1: This page has a very long list of words not to use: https://reservedwords.herokuapp.com/words Because 'class' comes up very commonly as a name with metaprogamming, I think the

问题 I was wondering why people don't use uppercase in name of header files. I see many header files with name only in lowercase. But I thought it would be more easy to read if they write them with uppercase, say "BaseClass.h", "SubClass.h", instead of "baseclass.h", "subclass.h". Why is that? Or it's just that the header files I've seen are named only in lowercase? 回答1: There are systems out there which are case-sensitive (*nix), and there are systems which are traditionally case-insensitive

问题 So, today while I was coding I found out that creating a function with the name init generated an error method init() not found , but when I renamed it to startup it all worked fine. Is the word "init" preserved for some internal operation in Go or am I'm missing something here? 回答1: Yes, the function init() is special. It is automatically executed when a package is loaded. Even the package main may contain one or more init() functions that are executed before the actual program begins: http:

问题 I think I'm trying to do something really simple. Using Spring Boot (1.3.3.RELEASE) with JPA I want to set a table name. @Entity @Table(name = "MyTable_name") public class MyTableData { ... } What I expect in my database is a table with "MyTable_name". Seems completely reasonable to me. But that doesn't happen. I get a table with name "MY_TABLE_NAME" (H2 backend) or "my_table_name" (Postgre backend). From here on I'll stick with Postgre since my goal is to read an existing DB where I don't

问题 Upon discussing the multiple-catch / combined catch block here with ambiguity between the terms "multiple catch block," meaning the Java 7 feature: try { .. } catch (ExceptionA | ExceptionB ex) { .. } and "multiple catch blocks," meaning literally, multiple catch blocks: } catch (ExceptionA exa) { .. } catch (ExceptionB exb) { .. } I've researched to see if the Java 7 feature has a specific, official name that can be used to clearly distinguish it from the older style of catching multiple
