As far as I am aware already the tasks that are listed out in the GSoC idea 
page have been completed by someone and there is a PR for that purpose also.

My apologies - I accidentally hit send mid reply.

You've got until Friday to get this proposal written and submitted to
Google, so if you're expecting to get feedback from the community and
integrate that feedback into your proposal, you're going to need to get
writing. Getting your proposal reviewed by the community isn't mandatory,
but all the successful proposals in past years have been through at least
one community review - I'd be very surprised if you can write an acceptable
proposal on your first attempt.

Yours,

Hi Shamim,

If you want to participate in the GSoC with Django, you'll need to write a
project proposal. This is a *lot* more work than saying "I'd like to work
on annotation". Here's a link to an example proposal from last year that
was successful:

[GSoC'14] Proposal: Improve annotation and aggregation

[Shamim Hasnath]

Hello,
I'm Shamim Hasnath, 3rd year student, studying CSE in Bangladesh University 
of Engineering & Technology (BUET), Dhaka, Bangladesh. Besides my studies I 
worked for over a year as a part time Django developer in a software 
company located in Dhaka, Bangladesh. I developed several Django & GAE apps 
there.

Here's my blog articles on 
django: http://www.hasnath.net/blog/category/django 

I'd like to work on *Improve annotation and aggregation. *I'm familiar with 
MySQL, Oracle, PostgreSQL and SQLite databases. I've checked all the 
tickets regarding this.

I have always wanted to contribute to Django project. GSoC would be a great 
opportunity for me.
Thank you.

Re: Improve annotation and aggregation

[Andre Terra]

Hey, Sagar,

I just wanted to say thank you in advance for tackling
Annotation/Aggregation. IIRC, Anssi Kääriäinen was working on a large ORM
refactor which put his improvements to aggregation on hold. It would be
worth checking out if he has moved forward, and I'm sure he will have more
than a few pointers to give you in this subject.

Off the top of my head, two tickets worth checking out are #11305 and
#14030, which are somewhat related and much needed by the community (me
included), based on what I saw in the comments. I've even helped bring the
patch to #11305 up to date twice, but it hasn't been merged pending said
refactoring and/or a solution to #14030.

https://code.djangoproject.com/ticket/11305
https://code.djangoproject.com/ticket/14030

Good luck and happy coding!


Cheers,
AT

Re: Improve annotation and aggregation

[Sagar Ghuge]

Thanks for Guidelines...I am aware about the GSoC 2014 timeline. That's why 
I am starting my work upon this as early as I can do. As you mentioned , I 
will try to tackle tickets and once I am familiar with the Django I will 
propose the project. :)

Hi Sagar,

You're a little early -- we haven't even begun to think about GSoC 2014
yet! However, if you have an interest in annotation and aggregation, that's
an area that could be a candidate for a GSoC project.

However, you're going to need to do two things:

1) Make a specific proposal. "Improve annotation and aggregation" is a
title, not a proposal. A GSoC proposal is a multi-page document, containing
detailed design plans, and a timetable on which we can evaluate your
progress.

2) Demonstrate that you know what you are doing. The annotation and
aggregation tools in Django are a complex part of the ORM framework.
Volunteering to mentor a GSoC student is a time consuming activity, so
mentors want to be sure that their time will be well spent. If you are
proposing a simple project, you would just need to demonstrate that you can
code. However, if you're proposing to dive deep into the ORM, you're going
to need to prove that you know what you're doing. This means developing a
reputation for working on hard problems in the ORM.

In short, we're not going to approve a project unless we know what we're
going to get at the end, and we have confidence that you are capable of
delivering that product.

The good news is that you have several months to do both of these things.
GSoC 2014 won't open until March/April, so you have three months in which
you can work on smaller existing tickets to establish your credentials, and
develop a plan for what you want to tackle in the GSoC. Take that time to
get familiar with the Django codebase, and take a look at some existing
tickets against the ORM [1]. See if you can develop fixes for some of those
tickets - especially if there are any tickets related to aggregation.

Once you've done a few tickets, start working on a draft for your GSoC
proposal. Look in the Django-develoeprs archives for examples of past
successful proposals, and try your hand at a draft of your own proposal.
Send that draft to django-developers, indicating that you're looking for
feedback. If you start on this drafting process early, the chance of your
proposal being picked up is much higher, because you'll get much more
feedback than someone who submits a proposal on the last day and gets no
feedback.

I hope I haven't scared you off! Best of luck with your GSoC aspirations!

Improve annotation and aggregation

Hi,

I am planning to participate in GSOC 2014 and i would like to contribute in 
Django as it is working on my area of interest that is Python. Is anybody 
working on this project. Or can any one mentor me or Guide me through this. 
I forgot to mention that I am totally new to this as I have an overview 
about the what Django is and all. Thanks.

Hi Russell,

Thanks for the response.
Clearly I don't have enough time to prove my eligibility to pull it off. 
Guess I will hang around here outside GSoC and look forward to contributing 
till the extent of my capabilities :).

Re: Improve annotation and aggregation

[Andre Terra]

May I recommend you browse Trac and take a look at the pending tickets
regarding aggregation?

This query should give you enough food for thought: http://goo.gl/vvraU

It is my understanding that Anssi Kääriäinen is working on an ORM refactor,
so speaking to him seems fundamental if you really want to move forward
with this, even with the imminent deadline. Some of the tickets you'll find
in that query may even have patches, but with the ongoing refactoring it
seems as if they're shooting at a moving target.


Cheers.

At present, this isn't an especially compelling proposal.

The bulk of what you're proposing is extremely vague. The #10929 default
NULL issue is well known and understood, but detail on your other proposal
goes no further than "should be simpler". We agree. Now, how are you going
to do that? You haven't given an API proposal, and you're not previously
known to the wider community, so we can't judge whether you have good API
design skills, or whether you've looked at any of the internals to
determine if what you're proposing is technically feasible given the
existing infrastructure.

On top of that, based on no experience with the query internals, you've
assumed that you'll be able to understand the internals of Django's query
engine, and then design and get consensus on an API plan in a 2 week
window. That's… ambitious.

Then you've got a 7 week block to implement this plan. This sort of
granularity gives us no confidence that you in any way understand the task
ahead of you. If you can't provide a plan at the granularity of days, or a
week at the *most*, then it's safe to say you haven't actually thought in
detail about the complexity of the problem you're proposing to solve.

You're proposing a deep dive into the internals of Django's query
infrastructure. Committing to being a mentor for the GSoC is a big
commitment, and there is a limited number of people who are in a position
to mentor you on this project. When combined with the vagueness of what
you're proposing, you haven't exactly inspired the confidence you'll need
to convince someone to commit to mentoring you.

If you want to be selected for the GSoC, you'll need to provide a lot more
details -- most importantly, evidence that you've thought about the problem
at a level beyond "this looks like a nice problem".

Yours,
Russ Magee %-)
