Zero Downtime Field Type Changes

['Kyle Mulka' via Django users]

Hi there,

Wondering if there's any tool out there to make a zero downtime field type 
change easier. I want to change a django model field from one type to 
another, and the format of the field in the database is slightly different.

I've come up with a process I think will work, but it will be rather 
tedious if done manually. Wondering if there's a more automated approach or 
other tools out there already. I'd like to come up with a general solution 
for use in the future, but right now trying to tackle converting UUIDField 
from django-extensions to the built in django version.
https://github.com/django-extensions/django-extensions/issues/647

I was thinking about maybe using a custom field that supports both types, 
but not exactly sure how to write a custom field that would do that.

If it helps, the manual process I'm thinking about kind of goes as follows:

# existing model:
class Model:
field = OldField()

# add field_old with OldField type
# when updating or adding rows start writing to both fields
# copy data from field to field_old
class Model:
field = OldField()
field_old = OldField()

# stop using field, only use field_old
# remove field
class Model:
field_old = OldField()

# create field with new type
# when updating or adding rows start writing to both fields in their 
respective formats
# copy data from field_old in old format to field in new format
class Model:
field = NewField()
field_old = OldField()

# stop using field_old
# remove field_old
class Model:
field = NewField()

Thanks for your help!

Re: Django csv file

[Chetan Ganji]

I would suggest you use transactions for inserting those many documents.
https://www.mongodb.com/transactions

Django ORM does not support MongoDB. So, you can't use models/ORM/Class
Based Views of Django with mongo.
Only way I know to use Mongo with Django is function based views. There are
some third party MONGO ORMS for django, but I never used them so far, so
can't comment on how good they are or are not. Do your R and find it out
;-)

I hope this helps you. Cheers!

If I were you, I'd work through the Django tutorial first. Then ask specific 
questions if you have any.

Re: Hello From Nigeria

[Eugène Ngontang]

Hello,

My name is Eugene. I'm from Cameroon, being an SRE-SE Engineer and Linux
expert as you can see here in my LinkedIn profile
https://www.linkedin.com/in/nixmind/.

I've founded leading a social movement I created since 2016, called Les
Castors Du Numérique (I speak french and english, but live in France
actually, and we are english and french guys in the association, from
multiple countries).
Here is the little site I built to juste let people know the vision
(actually in french, but will totally rebuilt in english and french) :
*https://www.lescdn.com/
*

The aim is to provide Africa folks with a pure playground to play and
practice tech, convivially.
We are just starting concrete things/activities, cause I think big and want
pragmatism in our actions, and we are building a collaborative expertise
platform for the association.
So if you guys are one involved in tech, wishing to acquire and/or share
experience, expertise.. you can join us, without any protocol

Our actual main project is to build a collaborative expertise platform as
stated above, but before get there, I've created  an interactive slack
workspace, where we can talk, have fun and emulate each other, and guys
like would pretty stimulate the movement, and why not work together to
build this platform???

Here is the workspace url : *https://lescastorsdunumrique.slack.com
*, but I need to send you
invitation in your mailboxes...

Thus dear geeks brothers/friends, do you allow me to invite you there, so
that we can create a "*django-users"* chanel for django specific purposes,
while you could still explore other channels to acquire/share more
knowledge?
If yes, please reply to me with your email addresses ...

Let me know if you have any question, I'll be pleased to answer and having
you join us for a pragmatic action and vision, with highest value.

Thank you for your attention.

Kind regards,
Eugène NG
