Part V Model LayerCreate an app project. The difference between app and project reference Djangobook is: A project contains a number of Django apps and their configuration. Technically, project's role is to provide configuration files, such as where to define database connection information, the list of installed apps, Template_dirs , and so on.

For today's WebService development, we have at least two options: SOAPWSDLUDDI series; REST-style architecture series !!! In the field of Bioinformatics (Bioinformatics), WebService is an important data exchange technology and will be more important in the future. Currently, EBI provides two types of services: SOAP and REST, whether data service or computing service (computing task submission ). 1 Python + SOAP/WSDL/UDDI The most common practice (per

In the field of Bioinformatics (Bioinformatics), WebService is an important data exchange technology and will be more important in the future. Currently, EBI provides two types of services: SOAP and REST, whether data service or computing service (computing task submission ). 1 Python + SOAP/WSDL/UDDI The most common practice (personal opinion) is to use python ZSI2.0, and ZSI also relies on LIB such as SOAPpy and pyXML. Many people are familiar with the SOAP protocol, and many existing applicat

request via a URL, the Django route sends the request to the view function, 2, then the view function will first go to the template, 3. Render the variable with {{Current_User}} in the template with the value defined in the view and convert the template content to a string after rendering 4. Return the generated string as a whole to the user Filter filtersTemplate filters are the way that variables are converted before they are displ

One, the Django framework1. HTTP encapsulates the entire process of a Web service. Consists of two parts: request and Response (response).The requested content is a URL (the path to the document). The response is mainly the body and the corresponding header (header)2. Data store database definition and Query database language SQL (Structured Query language) map to object-oriented language code object ORM (O

Fourth Chapter TemplateIn the previous chapter, we mixed the HTML code with the Python code in the view.py file. But the disadvantage of doing so is undoubtedly obvious, citing Djangobook's argument: Any changes to the design of the page must be modified accordingly to the Python code. Site design modifications are often much more frequent than the underlying Python code, so it would be much easier to change the design without Python code modifications. Python code writin

"HTTP protocol and JSON"1. HTTP protocolFeatures are as follows:(1) Support client/server mode.Simple and fast: When a customer requests a service from the server, it simply transmits the request method and path. The request method commonly has get, POST. Each method specifies a different type of contact between the customer and the server. Because the HTTP protocol is simple, the HTTP server's program size is small, so the communication speed is fast.(2) Flexible: HTTP allows the transfer of an
