Split Python Flask app into multiple files

阅读更多关于 Split Python Flask app into multiple files

I'm having trouble understanding how to split a flask app into multiple files. I'm creating a web service and I want to split the api's into different files (AccountAPI.py, UploadAPI.py, ...), just so I don't have one huge python file. I've read that you can do this with Blueprints, but I'm not entirely sure that route is the right one for me. Ultimately I want to run one Main python file and include other files so that when it runs, they are considered one big file. For example if I have Main.py and AccountAPI.py I want to be able to do this: Main.py: from flask import Flask import AccountAPI

Organization of C files

问题 I'm used to doing all my coding in one C file. However, I'm working on a project large enough that it becomes impractical to do so. I've been #including them together but I've run into cases where I'm #including some files multiple times, etc. I've heard of .h files, but I'm not sure what their function is (or why having 2 files is better than 1). What strategies should I use for organizing my code? Is it possible to separate "public" functions from "private" ones for a particular file? This

Multiple classes in a header file vs. a single header file per class

阅读更多关于 Multiple classes in a header file vs. a single header file per class

问题 For whatever reason, our company has a coding guideline that states: Each class shall have it's own header and implementation file. So if we wrote a class called MyString we would need an associated MyStringh.h and MyString.cxx . Does anyone else do this? Has anyone seen any compiling performance repercussions as a result? Does 5000 classes in 10000 files compile just as quickly as 5000 classes in 2500 files? If not, is the difference noticeable? [We code C++ and use GCC 3.4.4 as our everyday

How to store images in your filesystem

阅读更多关于 How to store images in your filesystem

问题 Currently, I\'ve got images (max. 6MB) stored as BLOB in a InnoDB table. As the size of the data is growing, the nightly backup is growing slower and slower hindering normal performance. So, the binary data needs to go to the file system. (pointers to the files will be kept in the DB.) The data has a tree like relation: - main site - user_0 - album_0 - album_1 - album_n - user_1 - user_n etc... Now I want the data to be distributed evenly trough the directory structure. How should I

Should I use #include in headers?

阅读更多关于 Should I use #include in headers?

问题 Is it necessary to #include some file, if inside a header (*.h), types defined in this file are used? For instance, if I use GLib and wish to use the gchar basic type in a structure defined in my header, is it necessary to do a #include <glib.h> , knowing that I already have it in my *.c file? If yes do I also have to put it between the #ifndef and #define or after the #define ? 回答1: NASA's Goddard Space Flight Center (GSFC) rules for headers in C state that it must be possible to include a
