Cord query.Namespaces are declared primarily in the Cactiverecord::scopes () method, and the format is Name-criteria pairs. The following code declares two namespaces in the Post model class, published and recently:
The code is as follows
Copy Code
Class Post extends Cactiverecord{......Public Function scopes (){Return Array (' Published ' =gt;array (' Condition ' =gt; ' Status=1 ',),' Recently ' =gt;array (' Order ' =gt; ' Create Time DESC ',' Limit ' =gt;5,),);}}
$.each (Array, [callback]) traversal [common]Explanation: Unlike the $.each () method of the JQuery object, this method can be used to sample any object (not just the array oh ~). The callback function has two parameters: the first is the index of the member or array of the object, and the second is the corresponding variable or content. If you need to exit each loop so that the callback function returns false, the other return values are ignored.Each traversal, believed to be new, is a variant
Demo the array used
Copy Code code as follows:
var _mozi=[' mohism ', ' Mo-tse ', ' Modi ', ' love not attack ', ' still with Shangxian '];

Copy Code code as follows:
$.each (_mozi,function (key,val) {
The callback function has two parameters, the first is the element index, and the second is the current value

A String object is called immutable (read-only), and because its value cannot was modified after it had been created. Methods that appear to modify a string object actually return a new string object that contains the Modi Fication.Because strings is immutable, string manipulation routines that perform repeated additions or deletions to what appears t O is a single string can exact a significant performance penalty. stringbuilder class instead of t

The field name should be confirmed by a design document, or at least everyone has a common place to mark it. problems are found before many codes are coded and gradually accumulated into specifications.

Modi's answer is a good design rule that helps you avoid such problems in new projects. In contrast, I agree with this answer, such fields and table names in historical pr

About Kubernetes Master Multi-node and high-availability, the online approach takes a active-standby approach, namely:Using software such as pacemaker makes certain master services (Apiserver,scheduler,controller-manager) run only one instance at a time. Specifically, if you have more than one master node, Scheduler,controller-manager is installed on it, Apiserver:
For Schduler services, run only on one master node at a time,
For Controller-manager, run only on one master node at a

Chris Yue's answer is to see a recruit to help you solve the legacy of history.
Modi's answer is good design rules that can help you avoid this kind of problem in new projects, by contrast, I agree with the answer that this type of field and table name in a history project is best done by refactoring.
There are many features that PDO does not support, such as SELECT * FROM table_name where ID in (: id_list
