Flask + mod_wsgi + Apache on Windows is deployed successfully (you can ask questions at any time), flaskmod_wsgiPreface The preface is purely an explanation. If you are in a hurry, you can skip this part. I promise not to hide any useful content here. When people are older, they may be overwhelmed. It took me about two weeks to successfully deploy flask on windows. Fortunately, I did not give up and finally

I have been studying flask recently. Since the HTTP interface provided by gfirefly uses flask, it used to write some simple operations in the game. Recently, many flask operations have been involved, so I studied it carefully. I have some experience with the request context and app context of flask, so I would like to

Flask relies on two external libraries: Werkzeug and JINJA2. Werkzeug is a toolset for WSGI (a standard Python interface developed and deployed between Web applications and multiple servers), JINJA2 is responsible for rendering the template. First, installation Prerequisites for flask Installation 1. The python2.x version is installed 2. Easy_install installed Before installing

Review In the previous series, we created a database and learned to populate it with users and emails, but we haven't been able to implant into our programs yet. Before two chapters, we've seen how to create a Web form and leave a full login form. In this article, we will build and implement our own user login system based on the Web Forms and databases we have learned. At the end of the tutorial we will implement new user registration, login and exit functions. To keep up with this chapter,

Storing data in a database is an integral part of any software application. Regardless of the control of the database there is a master control of that data. Blockchain technology stores data in chunks within a blockchain network. As a result, as long as a node is synchronized with the network, they get a copy of the data in the chunk. Therefore, there is no specific data master in this technology.In this tutorial, we'll write a smart contract (which I'll explain further) to keep the user data o

This article mainly describes how to use the flask to manipulate the database.The database saves the program data according to certain rules, and the program initiates the query to retrieve the required data. Web programs are most commonly based on relational model databases, which are also called SQL data because they use structured query statements. In recent years, however, document databases and key values have become a popular alternative to data

While Flask is a lightweight framework, it also provides many convenient features such as unit testing and database migration for large Web applications, so let's look at the structure of building large Web applications using the Python flask Framework Example: While small Web applications can be handy with a single script, this approach does not scale well. As applications become more complex, processing

This article describes how to implement full-text search in the Python Flask framework. this basic web function is very simple to implement. For more information, see Getting started with the full-text search engine Unfortunately, the full-text search support of relational databases is not standardized. Different databases use their own methods for full-text retrieval, and SQLAlchemy does not provide a good abstraction for full-text retrieval. We now

This is the third article in The Flask framework's Learning Guide series. it mainly tells you how to create the flask login management module. if you have any need, refer to continue the flask learning journey. Today we will introduce the flask login management module. do you still remember the blog project we wrote in

Use the Python Flask framework to construct the structure example of a large Web application, pythonflask Although small web applications can be easily expanded with a single script, this method cannot be well expanded. As the application becomes more complex, processing in a single large source file becomes more and more problematic. Unlike most other web frameworks, Flask does not have a specific way of o
