alias

问题 I'm trying to deploy a cakephp 3.1 app in a apache 2.4 powered server. My boss would like to place the app in a directory different of server's documentroot ( DocumentRoot "/var/www/html" in my httpd.conf file), since multiple webapps will be served by this server. Instead of virtualhosts, he would like to use aliases (host/app1, host/app2 etc). So I'm trying to configure it this way. I put an alias to my cake app ( Alias "/scqa" "/opt/scqa/webroot" in my httpd.conf file) and wrote a

问题 In the cluster that I am working on there are two main indexes, let's say indexA and indexB but these two indexes are indexed each day so normaly I have indexA-{+YYYY.MM.dd} and indexB-{+YYYY.MM.dd} . What I want is to have one alias that gathers indexA-{+YYYY.MM.dd} and indexB-{+YYYY.MM.dd} together and named alias-{+YYYY.MM.dd} . Does anyone know how to gather two indexes in one alias with logstash ? Thank you in advance 回答1: As far as I know, there's no way to do it with logstash directly.

问题 I have a bunch of handy aliases set up in the config file for my git repository. I will occasionally clone this repository (e.g. onto my laptop), but the clone does not included any of the aliases I've set up, presumably because the clone does not copy the git config file where the aliases are stored. I would, however, like to have these aliases available when working with the clone without having to set them up again manually. Has anyone found a good solution for this? 回答1: You can put

问题 Could someone please guide me on how to use alias in jOOQ. I tried looking into jOOQ documentation but it is not clear. Please provide an example if possible. 回答1: Both org.jooq.Table and org.jooq.Field types implement org.jooq.AliasProvider. This means, that you can call as(String) on them, to create an aliased object. Example: Table<?> aliasedTable = MY_TABLE.as("t"); Field<?> aliasedField = MY_FIELD.as("f"); The examples from the jOOQ manual include: TBook book = T_BOOK.as("b"); TAuthor

问题 I have not been able to find the answer elsewhere, so I guess I just have to ask this one: I am trying to get an alias for a vector (in which int pointers are stored), as below: void conversion(Engine * ENGINES) {//The Engine class has a vector of int* as a public data member called SITE for (int i = 0; i < 3; i++) { vector <int*>* current = &(ENGINES[i].SITE);//the problematic line int j_max = current -> size(); cout << j_max << endl; for (int j = 0; j < j_max; j++) { for (int k = 0; k < 3;

问题 If I want to alias a template class for a known type in c++, I do something like this : using MyVector = std::vector<MyClass>; How do I ahieve the same for function templates? template <typename T> void MyFunction(T MyValue); I tried : using MyIntFunction = MyFunction<int>; But its not working. 回答1: Alias declarations are meant to introduce aliases for types. Anyway, you can use a constexpr variable to do what (I suspect) you are trying to do: constexpr auto MyIntFunction = &MyFunction<int>;

问题 I'm trying to join two tables in peewee with a mysql database. This is pretty easy doing something like this: s = Table1.select(Table1, Table2).join( Table2).naive().where(Table1.Title == "whatever") Unfortunately, I have called a column in Table1 and Table2 the same thing, "URL". Then when I select s.URL it gives me the URL from Table2, which I don't want, I want the one from Table1. Is there some way to either not join the Table2.URL column or to name it something different?

问题 Please excuse me if you find this a very lame questions, but since I am learning Powershell I need to ask. This is a sort of next part of the question posted and answer received here. I have a custom cmdlet named Get-DirectoryListing and I added an alias 'gdl' (using New-Alias command in .psm1 file). So user can use either Get-DirectoryListing or gdl to fire the same command. Now I want to detect in my code (.NET, C#) which text was used to execute the command. Lets say if user used alias

问题 I'm using Yii2 framework with advanced template.

问题 Does anyone know why I am not able to group TotalSales in this query and if so how can I fix this: select coalesce(Author_ID, 'All Authors') as Author_ID , case when Author_ID is null then ' ' else coalesce(Book_ID, 'All Books') end as Book_ID , TotalQuantity , coalesce(TotalSales, 'No Sales') as TotalSales from ( select author_id as Author_ID , book_id as Book_ID , sum(quantity) as TotalQuantity , sum(quantity * order_price) as TotalSales from a_bkinfo.book_authors join a_bkorders.order
