Blog related module on GAE (google app engine), including picture upload, client side javascript, server side, html editor, roles of visitor, admin, tag system, etc.
-
Seperation principle: every module shall function and have least relationship with other modules as possible.
-
I want some functionalities out of GAE so I can copy-paste these libraries and use it directly in different projects.
-
These functionalities are supposed to be related to 'blogs' and 'personal website' and 'shops', so I will gradually feed into this collection some functionalities.
This module represents a keystone of blog system, pictures.
The module to let user upload pictures by drag and drop. All the pictures are uploaded and transformed into 1600px, 800px, 512px and 256px for web serving. Blog admin can easily refer to a single transformed image via a key. picture represents an image resource collection.
This module represents a keystrone of blog system, articles.
Also this module contains other fields like tag and language_tag data structures.
Unlike usual articles, web blogs are comprised of HTML tags. article mainly represents a kind of text based objects.
So the functionality will let user insert html articles, view the article on the fly while he/she is typing, and save the article into database
User shall be able to do CRUD(Create, Remove, Update and Delete) functionalities, see the handlers.py for more detailed operations.
