The "killer" features I am hoping to bring to the Django community is the ability to have strong data consistency assurances between requests when editing data, as well as realtime server-driven validation of form inputs, alongside optional realtime "autosaving" of fields as changes are made. You can see how this looks here: https://user-images.githubusercontent.com/236562/153730557-a...
I have also attempted to minimise how much an existing codebase needs to be altered to use or test this. No database schema changes are required, and mostly it's just a matter of changing import statements from "django..." to "nango..."
This is very much a proof-of-concept at the moment and certainly not fit for production, and I welcome all suggestions and critiques. A quickstart script is included in the repo which should minimise the pain in running the code locally.
Django forms having this problem is, in my opinion, WAY down the list of problems. I originally wrote the forms library in iommi to be able to programmatically create forms in a sane way but it has since evolved to fix many more of the weaknesses of django. Some highlights:
- good rendering of forms to html!
- that can be customized without resorting to writing gigantic amounts of brittle template code
- render form errors
- strip space from inputs by default
- always writes the encoding attr so file uploads work by default instead of silently failing by default
- you don't need to manually pass request.FILES (another silent failure not just beginners get bitten by)
- don't allow misses like duplicate names that causes silent data loss
Plus the iommi features of nesting and having multiple forms/tables/menus/etc on one page with clean composition.
The main driver for getting it done is mostly to set the groundwork for the websocket autosave feature, which would be exceeding dangerous without this.
Remember that this is not a SPA, so websockets are recreated each time a page containing models marked for dynamic updates is served. This means there should be fewer problems associated with long-lived connections, and any instability will have more limited impact.
