Yu Cao Code Review

Structure

Firstly I would say the file construction is really good, seems everything is in great order. Readme files and comments in code are sufficient. Makes me easy to understand your project's structure and what each file is about. But one suggestion is that in your code, maybe you can add more comments in it to make it more understandable. And also that will help you guys to modify things later .

Also some name of the html files should be modified to clearify its usage.

And you should think of adding license to your project.

Code

Firstly, I think maybe you can check your python codes's style. Follow the instruction of pylint and maybe make the code more elegant.

What's more, when I'm reading the mongodb part, I find out that you are using the local host for now, this maybe the part you can improve.
