Hi, first of all check your models, did you use custom through model for m2m field.
Try to check foreign key constraints of middle_table_for_m2m_field in your current database, probably something in migrations has gone wrong.

Please provide a full explanation including all the details that you consider relevant. Your statement is too broad and there is no clear way to answer you, you have to explain:
- what you're doing
- what you're expecting
- what you're using
- where you're running the script
- what Python version you're using
- what packages and their versions you're using
- and the most important thing: show the code YOU wrote (read rule 5️⃣ for that)
and more details, that way your chances to get help will increase

hey, there's so many IDLE connections that django ORM leaves behind in one of my project, in the other ones, it's fine. both are using same postgres server, and I don't understand why this happens.
I've set my connect_timeout to 5 secs, and CONN_MAX_AGE to 0

Such problems are hard to debug, because there are many reasons for that. You have to explain your project setup - who is using the DB, how my apps consumes it, how many processes those apps have and etc etc.
Alex
Normally django ends all db connections after it complete an http cycle

I'm using a PaaS service, I have 2 django projects on 2 servers, that both are connected to a postgresql v11.
The database has 4GB ram, 2 core CPU, meanwhile each server has 2GB RAM with 1 core.
As explained, I set CONN_MAX_AGE to 0, and connect_timeout to 5. few days back, it was all fine, but now, with one of my project, there are usually 60 connections in IDLE, and 1-2 active connection. in the other application's database, according to pgadmin, there's 0 idle connection, with 1-2 active connection at max.
These IDLE connections has been remained from serval hours ago, and I need to terminate them manually, otherwise I get the error "fatal too many clients"

Yes and I know that,
but it remains in PG as idle, and I don't understand why. tried using a context manager to debug what's going on, but didn't spot anything suspecious. Also perform raw query and closed it myself, but once again, it remains as IDLE.
Restarted servers/db few times, it didn't help.
The only option is to increase the max connection to avoid fatal error, but once again, it's not the solution to my problem.

My best guess - are you using celery or some other similar framework? Or maybe some 3rd party app? Are those connections attached to your server processes?
Prathmesh
It is image of product.
How to use product ID to display image??
Mani
My best guess - are you using celery or some other similar framework? Or maybe some 3rd party app? Are those connections attached to your server processes?
No, everything is returned after HTTP requests, I'm using only one process per request and there's no multi processing or multi threading in parsing a request from user.
S.H.K
Django is suitable for how many users
Mani
I've to mention that my CONN_MAX_AGE was about 60, before.
but then, after getting this problem, I lowered it to 0, to close all. connections right after the response is sent, but for some reasons that I don't understand ,this doesn't happen.

Hello.
I dont have much experience.
Is there is some builtin opportunity to get next row from table?
Example:
class Image(models.Model):
id = models.BigAutoField(primary_key=True)
image = models.ImageField(upload_to=image_directory_path, blank=False)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
class Meta:
order_with_respect_to = 'id'
Рома
image = Image.objects.get(id=1) # got image here
next_image = image.get_next_in_order() # got Image matching query does not exist
# next_image = Image.objects.get(id=2) # direct request by id got it

Рома
if i right understand your question. As i know, get returns object, not queryset. Should i apply filter?
Fan / Ac

i dont know what exactly you are trying to do, if you need all items in the database, you could do Model.objects.all()
Fan / Ac
i think what you need to do is sort by created date in ascending order
Рома
i dont need all. I have some concrete and i want to get next to it
Fan / Ac
i dont need all. I have some concrete and i want to get next to it
it does not retrieve all, it's just a generator, django filters are lazy
Kiarash
Hi , can you introduce some good intermediate/advanced django books ? 👍
Fan / Ac
i dont need all. I have some concrete and i want to get next to it
not sure is this is the correct syntax but try this
Model.objects.all().order_by('-date')
Fan / Ac
and iterate through the generator it return
Рома
and iterate through the generator it return
Your solution is helpful. A bit not what i was looking for.
Result (as i know current id)
image = Image.objects.filter(id__gt=1).order_by('created')[:1]
Can it be improve? Or it is ok?
