Installing modules
Note: My operating environment is Ubuntu 10.04 and PostgreSQL 8.4.
First install the Postgresql-contrib package and restart the database server, and then check the contrib directory to see if there are any available modules:
sudo apt-get install postgresql-contrib
sudo/etc/init.d/postgresql-8.4 restart
cd/usr/share/postgresql/8.4 /contrib/
ls
Then we create a database call
Before I wrote an example, about thinkphp RBAC rights control, and then studied the next, found in the real situation, a lot of crm,cms, there is a need to acquire RBAC all the modules, and then the rights to assign operations, or to increase the deletion module.
So I thought of a way to achieve the automatic acquisition of thinkphp all modules
The general idea is:
1, according to the configuration file
. The process target of the ISAPI extension is the HTTP request. This means you have to call them to activate them. You can think of an ISAPI filter as just a filter. Each time the client makes a request to the server, the request passes through the filter. The client does not need to specify a filter in the request, simply send the request to the Web server, and the Web server passes the request to the relevant filter. The filter may then modify the request, perform some login operations, and s

A portal module combines some code and UI to present specific functionality to the user (for example, a threaded Discussio n) or render data, graphics and text, (for example, a "Sales by Region"). In addition, a portal module needs to know and the "interact with the" portal Framework to participate in the rendering, edit ING, caching and roles-based security services it provides.

Modules are the methods used to organize Python code, while packages are used to organize modules.When the code is very large, we usually divide the code into several organized pieces of code, and then there is a certain connection between each code snippet. The code is shared, so Python allows a module to be transferred, allowing the use of other modules ' properties to take advantage of previous work and
Linux Kernel Modules-general Linux technology-Linux programming and kernel information. For more information, see the following section. Linux is a single-kernel structure, that is, it is a large program, and any function can access the public data structure and other function calls. (As an operating system) another possible structure is multi-core. Each function block is a self-contained one, and each other is connected by a strict communication mech
ObjectiveMAVEN is used in the project, and the content used is not as simple as using maven/eclipse to build SSM (spring+spring mvc+mybatis) The core of Maven is pom.xml, so I'll talk about the different places.What impresses me most is the following four elements: modules, parent, properties, import.ModulesIn the literal sense, module is And Pom.xml in the modules is precisely this meaning, used to manage
In the previous article, we introduced the PEAR concept, encoding rules, and simple usage. You may have a preliminary understanding of it. This time, we will introduce the functions and usage of some modules in the existing PEAR library.I. Naming ConventionsBefore learning about the existing pear module, let's take a look at the Organization classification and naming conventions of PEAR. The module organization in PEAR is similar to that in CPAN. The
This article and everyone to share is mainly python in the package and module-related content, come together to see it, hope to learn Python to help you.Summary1. For reuse and better maintenance of code, Python uses modules and packages; a python file is a module that is a special directory (containing the __init__.py file) of the organization module.2. Module search path, Python interpreter search for modules
ModuleModule: The essence is a. py fileDivided into three parts: built-in modules, third-party modules, custom modulesModules: top-level files
python module Python module can split a code-heavy program into multiple organized, independent, but interactive pieces of code that are self-contained, organized snippets of code that are modules, The module is physi
PHP has three modes of collaboration with Apache: CGI, Modules, FastCGI.In CGI mode, when a user requests a PHP file, Apache initiates the response process, invokes the PHP processor to process the request, and then returns the result to the client. User response and processing is done by the front-end Apache server;In modules mode, the PHP parser acts as a module of Apache, and the PHP processor runs with

Modules allow you to logically organize your Python code snippets.Assigning the relevant code to a module will make your code better and easier to understand.The module is also a Python object, with a random name attribute used to bind or reference.Simply put, the module is a file that holds the Python code. Modules can define functions, classes, and variables. The module can also contain executable code.Im
