Re: Locking / serializing access to one element in database

Hi Joakim, I would suggest you use select_for_update() in a transaction. It's hard to provide a full example without more details about the kind of calculation required. Does it need to be run on new_text even if n

Locking / serializing access to one element in database

Hello; this arises in the context of a django application - but it might be a more general Python/Postgres/... problem. [ The django application is existing all right - but the problem I am describing here is yet only in my head; I am seeking advice on how to proceed. ] Assume I have a model

Issues with django-storages and gunicorn processes

I am using django-storages to store media files in Amazon S3. Gunicorn spaws three worker processes, each running their own copy of S3BotoStorage. When I go into filebrowser and upload a file, the current worker process adds it to its entries list, and therefore knows that the file exists. When

I don’t have any experience with Crispy Forms, but I wonder if you get the same number of queries when you just print out the form and helper? On 20 October 2015 at 14:26:45, Fellipe Henrique (felli...@gmail.com) wrote: Here is my view, model and form:   https://gist.github.com/fellipeh/f10824e6

Re: Validating data for use directly in a model (not via forms)

Thanks, yes I did look at model validation in the docs - it looked to be tied to use via forms. I hadn't realised that it's not called automatically when an instance is created. So if I was to validate when using get_or_create method would I then manually call full_clean() after get_or_create

Re: Validating data for use directly in a model (not via forms)

Hi Yunti, Did you read about model level validation ? Calling model_instance.full_clean() triggers validation but it's not implicitly called when you save an instance. For your date case you'll have to include a l

Validating data for use directly in a model (not via forms)

I have a django project where I want to save web scraped data to the database via the django ORM- which will be used in the django app. The data is currently in the form of JSON -> converted to python dict via json.loads I setup my model with the narrowest/ most constrained field type possible

Re: Use of transactions

Hi, it's hard to say without seeing more code. In my mind right now is something like: * First transaction start ** T1: It reads maximum from DB (lets say is 100) ** T1: It will create 101 ** T1: It will create 102 * T2: Let say at this moment second transaction start ** T2: It reads maximum from D

Re: Use of transactions

Hello! Thank you for answering. So if that's the case then what is happening is that (according to question 1) the second transaction is getting the same number as the first one and complaining with the IntegrityError while trying to save. Is that correct? On Wednesday, October 21, 2015 at 10:

Re: Use of transactions

Hi, Transactions are a different concept than locks. In few words a transaction means that the all the sentences within it are done or not done, but can't be half done (unless you have savepoints, and want to rollback to a particular point). The locks avoid other for making operations on the table

You need to call super() in your custom method to ensure the object is actually saved to the database. On Wednesday, October 21, 2015 at 8:12:24 AM UTC-4, Yaniv Mirel wrote: > > The Committee.save() is: > def save(self, *args, **kwargs): >if not self.slug: >self.slug = 'committee-

Re: save() prohibited to prevent data loss due to unsaved related object 'committee'

The Committee.save() is: def save(self, *args, **kwargs): if not self.slug: self.slug = 'committee-%s' % self.id And yes, after removing that save function everything works fine. On Tuesday, October 20, 2015 at 9:32:20 PM UTC+3, Tim Graham wrote: > > What does the Committee.save() m
