two-stage submission of django forms
I have a django model that looks something like this: class MyModel(models.Model): a = models.BooleanField(default=False) b = models.CharField(max_length=33, blank=False) c = models.CharField(max_length=40, blank=True) and a corresponding form class MyForm(ModelForm): class Meta: model = MyModel Asking the user to fill in the form is a two phase process. First I ask whether a is True or False. After a submit (would be better maybe with ajax, but keep it simple at first) I can fill in a dropdown list with choices for b and decide whether or not to show c as an option. No need to show a as a choice any more, it's descriptive text. So I want to present a form twice, and the same model is behind it, slowly being filled in. First choose a, then be reminded that a is True and be asked about b and c. Or that a is False and be asked about only b. After submitting this second form, I save the object. I'm not clear how best to do this in django. One way is to make two separate form classes, one of which has hidden fields. But if the same model is behind both and the model has required … -

Django and sites: reloading staging db
Loading production snapshots of my django database on staging used to be easy: python manage dumpdata / python manage loaddata or even pg_dump / pg_restore. We're now using the Sites module and detecting site based on http request. (Setting by primary key in the Sites table is fragile.) So if I do the dump/restore above, I'll overwrite Sites hostnames. Production is expecting site names like 'www.example.com' while staging is expecting names like 'staging.example.com'. One way around this is to write some wrapper around the dump/restore so that the site data is modified on restore. Another solution (which I believe would fail, see next sentence) is just to enter the staging site data in production so that it is present on staging. A problem with this last approach is site equivalence: some features activate if site is example.com but not example.de, say, and the models that do this key on site.id, which is different between www and staging. Are there common idioms for approaching this that I've missed? I'm sure I can get this to work, but I'm merely concerned that I haven't seen "best practice" advice on this, which makes me think I've missed something. Thanks for any tips. -
Why the data from the database is not displayed in the Frontend?
I'm trying to fetch data from my database to the frontend and display with datatables. This is what my view function looks like: (I tried both the comment part too but without success) def displayPatientsToFrontend(request): patients = Patient.objects.all() #patients_json = serializers.serialize('json', patients) #return JsonResponse({'patients_json': patients_json}) return JsonResponse({'patients': patients}) my jQuery script: $(document).ready(function() { var data; fetch("http://192.168.1.32:8000/displayPatientsToFrontend/") //.then(response => response.text()) //.then(text => console.log("text is: " + text)) .then(response => response.json()) .then(json => data = json) .then(() => {console.log(data); $('#datatable').DataTable( { data: data.patients, deferRender: true, scrollY: false, scrollX: false, scrollCollapse: true, scroller: true, columns: [ { data: "id" }, { data: "first_name" }, { data: "last_name" }, { data: "email" }, { data: "date1" }, { data: "date2" }, ] } ) }) } ); The problem is that the data doesn't want to display in the datatables. I believe there is a mistake in the promise in the jQuery script. The error I got is: Failed to load resource: the server responded with a status of 404 (Not Found) and Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0 this is from DevTool and from django terminal I got: ** Not Found: /displayPatientsToFrontend/ ** Of course I define … -
