5、mswineCommon requirements Let content authors create chunks and upload files Chunks and files get tagged and categorized Not all objects have files-the UI cant freak out when it comes across content-less objects Front-end web site needs to be able to query for chunks, files, and content-less objects

6、 The front-end web site cannot look like Share Our users arent teams They dont care about “document libraries”A simple example: To DoBasic requirements End users create/manage to do list items To do list items are tagged End users can upload documents related to To DosExtended requirements Certain c

7、ategories of To Do Lists have associated content chunks that need to be displayed. Example: To do list that is categorized as Writing should display with content chunks that give advice on writing.

8、s are objects. Ill map URLs to various views on those objects. Ill probably use a relational database to persist everything except the files, which Ill let my framework handle. Files are documents. Thats easy. To Dos are “content-less” objects. I need to figure out a folder for all of this stuff to

9、live in and how I want to relate To Dos to files. Ill map URLs to various views which will request data from the repository via REST.Five-minute look at Django Creating a new Django app Defining a content model Creating a template Model View Controller Using the admin site to edit object instancesSo
