Re: How to clean a model after the related models inline forms have been saved?

Please forget about the persisting data part. The problem is that inside the parent form i dont have access to the related data and the formsets new related data is validated after the parent models data. Inside the formset every related data model does not have access to the other related inst

Re: How to clean a model after the related models inline forms have been saved?

I still don't understand why you want to persist unvalidated data to the db then? if a user requests the data in mid-update, that's something that can be handled with transaction locks on the db. so when that happens, the request will wait till the locks are released before executing the db qu

I think we're missing a few things. how fast does this query with updated values execute after the form submits? if you need to return the value back to the view, can't you do some sort of post-save retrieval and form populate? -- You received this message because you are subscribed to the Go

How to clean a model after the related models inline forms have been saved?

I want to execute a check after the related data from the admin has been saved, but the default clean methods get executed before the formsets are saved. Where could i place my check to have access to a full version of what has been changed on the admin page? -- You received this message becau

Thank you in advanced) I actually know about the two versions of python the differences, and about not compatibility. So I've learned the main concerns in python and I just wanted to have a overlook to django yet not in real project. But the case I have mentioned was just for a non programmer a gr

Re: Documentation

Furthermore, the reason this isn't mentioned in the django docs is because its assumed the developer will have familiarity with python. I would suggest you get comfortable with python and then learn a framework like django/flask. Learning both at the same time can be done (I did it), but it w

Re: Documentation

basically, there's two versions of python: python 2 and 3. They're incompatible with each other, though there's ways you can get py2 code to run in py3 (the inverse is not true). Effectively, think of what ES6 would have been like if TC39 had the guts to make a backwards incompatible version

Documentation

Hi to all. In the documentation the whole examples are for machine that has only one python version installed. So I was trying for an hour to understand what I've done wrong with django instalation. But the reason was I was typing `python` instead of `python3`. Please give some note about that.

Re: Update data instead of creating a new row entry in django model

what you should do in your post check is bill_item = BillItem.objects.get(code = itemcode) form = BillItem(request.POST, instance = bill_item) This populates the form with the existing model instance and merges with the post data. you then can run form.save() to persist the update

Hi, Thanks for advice ^^ I have one new concern. Is there a limit for for Django model IDs? Now I have automated the data insert with python code loop, but the ID-number is not consecutive. It jumps for example from ...56 to 571... and from ...587 to 3763... and so forth. Do you know why it is
