Re: Django tutor.

Honestly this Django community is cool, you can ask any question.
What do you want to do ? Django rest API or 
Django in full stack ?

Bien cordialement,

Julien Munar.

Re: ForeignKey Reverse Relation Fail

[Malik Rumi]

Thanks, but the recursive foreignkey *is* a one to many relationship...
unless you're talking about something else?

Re: Best digital ocean plan for a production server

[Ram]

Hi Abdul,

Thank you for your suggestion, but since you mentioned Docker image in your
earlier email, I've listed all my software stack that is required for our
Web Application. So I'm looking for any managed solution from any provider
that can help us to focus only on coding. It does not have to be Kubernetes
solution and anything is fine as long as we don't have to spend time on
infrastructure and yet scalable & feasible.

Also, along with the previous list of software stack, we are planning to
develop Django REST APIs and a mobile app using Flutter which could add
additional software to the list.

I explored both Digital Ocean and Heroku so far and I'm struggling to find
the right solution from both of them. So I emailed them to see what they
can recommend to us.

Best regards,
~Ram

 Hi,

 We are planning to launch our application in production once all the
 testing is completed after deployment to our development server. We are
 using Jenkins CI automation to deploy the code to the development server
 and we will do the same in production server too, but we are currently
 doing a feasibility study to understand which options are good for Django
 web application for both Web and Mobile app.

 If anyone in this Django users community is currently on any Digital
 Ocean's production server plan, could you share some details and
 suggestions.

ForeignKey Reverse Relation Fail

[Malik Rumi]

I have a model with a recursive foreign key to 'self'. This is intended to 
model a parent child
relation among instances. The forward relation, on a field called 
'childof', works as expected.
The reverse relation, using the related_name 'parent', comes up as a 
RelatedManager,
again as expected. However, parent.count(), parent.all(), etc., always give 
me the "Manager is
not accessible on instances" error. Many of these parent instances will 
themselves also be a
childof some other instance, and apparently, that's my problem. I don't 
know how to make Django
recognize the dual nature of some instances. Is there a way to hack the 
RelatedManager to fix this?

I am not getting any accessor errors from manage.py check.

I posted this to Django Forum, but the respondent was not able to duplicate 
my issue - i.e.,
he said it worked as expected for him. :-(

I saw a suggestion to use an explicit junction table on Stack Overflow, but 
making a round trip - or two - to an external table seems like an
awful lot of overhead for this situation.

If instead of a junction table, if I made an explicit parentto field on the 
model, would that work?
Presumably the related name on the childof field would still fail like it 
does now,
but I would instead have the explicit parent field to work with. I still 
would not have the
automatic reverse relation, and I would have to come up with a script to 
fill in the parentto
field, but that might solve my problem:
# pseudocode
family = c.itertools.groupby(instance.childof)
family = c.pandas.groupby(instance.childof)
for f in family:
pop = c.objects.get(instance.childof)
OR
pop = instance.childof
c.objects.update(pop.parentto=f) # where parentto is a Postgresql ArrayField
OR # 
https://docs.djangoproject.com/en/4.0/ref/models/relations/#django.db.models
.fields.related.RelatedManager.add:
>>> b = Blog.objects.get(id=1)
>>> e = Entry.objects.get(id=234)
>>> b.entry_set.add(e) # Associates Entry e with Blog b
SEE ALSO: 
https://docs.djangoproject.com/en/4.0/topics/db/examples/many_to_one/

If I did this two field hack, then I don't really need either one to be 
ForeignKeys any more,
do I? They could be a CharField and an ArrayField, couldn't they? That 
breaks the extended 
lookup chain - but I don't have that now, anyway - or at least, I only have 
it in one direction.
