CM2301 Group Project - Decentralised Online Learning System

CM2301 Group Project

Our wonderful, marvelous, beautiful group coursework code - written in Django.

###Create your own branch, then push changes and submit a pull request. This is important.

Please stick to Python code convention

Requirements

• Django 1.5
• UUIDField - "pip install django-uuidfield" should do it.
• ffmpeg

cm2301-9's Issues

Revision Versioning

Currently if you delete a revision then add another then it fucks the revision numbers.

Hashing with Password

Django Admin need resolving with HASH generator

Inefficient counting of objects

When counting the total of multiple fields we shouldn't be fetching the entire data set, for example calculating the total size of an attachment we should be using djangos aggregate query.

https://docs.djangoproject.com/en/dev/ref/models/querysets/

Then the load is on the database.

User Login and Permissions System

Bootstrap WYSIWYG

A bootstrap looking javascript text editor should be implemented across the site for creating descriptions with markup. e.g

• Coursework Tasks
• Lecture Descriptions
• Module Descriptions
• Any other TextField

Bootstrap-WYSIWYG

Rest of Django models need to be written

Rest of remaining django models need to be written and documented for https://github.com/JosephRedfern/CM2301-9/blob/master/CM2301/Learn/models.py

Lecture Management

Lecturers need to be able to add/remove/edit lectures, and their associated videos/attachments.

Completion of this milestone relies on the Attachments Milestone being completed.

No pagination for data

For a lot of data tables and pages we have no pagination, this potentially could be an issue in the long time, although this is of low importance for now.

Ability to add lectures

Lecturers need to be able to add lectures.

After-lecture test

Submit Coursework

A user needs to be able to submit coursework.

Design URL Layout

We need to come up with a layout for our URLs. i.e:

/module/lecture/lecturetitle

for all features

Explain current system

Rest of the group needs to know how the system works so far.

Learn Git

User Management

An administrator needs to be able to add users - both students and lecturers.

Show percentage in video conversion progress bar

Might be nice... not urgent

Video conversion progress bar jumping

When converting videos it seems the progress bar jumps back when one video finishes converting, this does not affect functionality so is relatively cosmetic. Probably a simple case of making sure the _update_progress() method is exiting the loop at the correct time.

Dimensions must not be odd numbers in ffmpeg wrapper

With certain codecs if ffmpeg has to deal with an odd number then the encoding will not run, this can be avoided by ensuring when dimensions are parsed the scaled opposite is calculated and made even.

No File Attribute in the Attachment Class?

Line 132 of the models file:

The attachment attributes don't include a file_path variable, where does it get the file from? Is it inherited and I'm missing something?

Prevent potential database error logging logic error

When writing code for our logging system, we need to make sure that certain database errors aren't saved to the DB, as this could cause an infinte loop.

For example: If the MySQL Database was down, and our logging system attempted to log this to the Database as an error, then it would cause a database error (as the MySQL DB is down), which would in turn cause another database error as this error was logged... etc etc. You get the picture.

But yeah, we need to make sure that our Error Logging system is robust.

Use celery or other task queue.

We are currently using unmanaged threads to convert the video. We should instead be using a task queue to manage this.

Video thumbnail not selecting random one

Video thumbnails should be random upon page loading, currently the first in the list is being used.

Although to do this we need to create multiple thumbnails for a single video... shouldnt be too hard to do!

Separate into several apps

When we started the project, we stupidly thought that everything was all linked together. In hindsight, this was wrong.

We can divide our system into several apps:

• core
• video
• coursework
• faq
• announcements

etc etc

Progress Graphing

We can use Rickshaw for Progress Graphing, and it will be dead good.

User Management

We need to be add users and assign roles (Lecturer/User/Administrator etc)

Revision form failing to return validation errors.

When adding a revision to the attachment, if the filename is different it simply raises an unhandled exception. Errors need to be returned to the client.

Front-end for the Lecturer and some admins

we need to work on the browser based front-end for LCARS rather than Django Admin

Mark Coursework

Lecturers need to be able to download and mark users coursework submissions.

Video Conversion

If videos are uploaded directly to the site then they will need to be converted locally or use a conversion api to a third party provider.

Establish how videos will be stored

Videos could be stored in a variety of ways, potentially linking to youtube or another video hosting provider. However this does reduce control over the videos.

Export deadlines as .iCal

It would be beneficial for a user to be able to export their upcoming deadline/test dates to an iCal file/stream, or something similar.

Could use an ical python library like this.

Add Coursework Task

A lecturers needs to be able to add a coursework task

Original video files not saving as uuid of video object

When video files are uploaded they should be saving to /videos/original the the uuid of the video object the file belongs to, this will make it easier to identify and keep everything unique!.

It's all shit

Right now, it's all shit. We should fix it.

Add Attachments

Lecturers need to be able to add attachments to lectures and modules.

XML Test definition.

Allow users to upload/download tests as XML. Could be implemented along side a gui.

Generate some fucking documentation

@JosephRedfern needs to stop being a lazy prick and actually generate some documentation using either Sphinx or Doxygen. Some other wank excuse for a documentation generator could also be used.

Validation missing from some models

When handling data between initilialising and submitting a form its tricky to add data, because of that I made certain fields in Revision and Attachment blank=True and null=True, this should be removed and editable=False used instead.

This should stop validation from bein fucked
