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

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
