my models , views below.
models.py
class country(models.model): name = models.charfield(max_length=50) # indicators class indicator(models.model): target = models.foreignkey(target) number = models.charfield(max_length=5) # order integer indicating how areas should sequentially ordered # smallest integer should listed first order = models.integerfield(default=0) name = models.charfield(max_length=200) def __str__(self): if self.name: return self.value # reports class report(models.model): author = models.foreignkey('auth.user') country = models.foreignkey(country) created_date = models.datetimefield(default=timezone.now) # possible numeric score choice , associated display color class scorechoice(models.model): value = models.integerfield() name = models.charfield(max_length=50, null=true) color = models.charfield(max_length=10) description = models.textfield(blank=true, null=true) created_date = models.datetimefield(default=timezone.now) def __str__(self): if self.name: return str(self.value) # actual scores, value 1 of score choices # , belonging report , indicator class score(models.model): value = models.foreignkey(scorechoice, null=true) indicator = models.foreignkey(indicator, null=true) report = models.foreignkey(report, null=true) views.py
def report_create(request, pk): indicators = indicator.objects.order_by('order') # create new report country , associated report form report = report(country=country.objects.get(pk=pk), author=request.user) report_form = reportform(instance=report) scoreinlineformset = inlineformset_factory(report, score, fields=('indicator', 'value'), extra=len(indicators), can_delete=false) formset = scoreinlineformset(instance=report, initial=[{'indicator': i} in indicators]) if request.method == 'post': report_form = reportform(request.post, instance=report) formset = scoreinlineformset(request.post) if report_form.is_valid(): created_report = report_form.save(commit=false) formset = scoreinlineformset(request.post, instance=created_report) if formset.is_valid(): created_report.save() formset.save() return redirect('report_detail', pk=created_report.pk) return render(request, 'ghsanavigator/report_create.html', {'formset': formset, 'report_form': report_form, 'indicators': indicators, 'country': country.objects.get(pk=pk).name}) ----------
the first, , solved question summarized below reference (answered vgrubes)
how can change dropdown fields populated not "scorechoice object" actual score.scorechoice.value? same indicator dropdown fields.
i able achieve #2 simple modelform doing following, have no idea how inlineformset! , have no idea on how #1.
class scorechoicefield(modelchoicefield): def label_from_instance(self, obj): return "%s" % (obj.value) class scoreform(forms.modelform): value = scorechoicefield(queryset=scorechoice.objects.all()) ...
i can provide partial answer question. can specify unicode method in models return string instead of model object instance.
class indicator(models.model): target = models.foreignkey(target) number = models.charfield(max_length=5) order = models.integerfield(default=0) name = models.charfield(max_length=200) def __unicode__(self): if self.name: return self.name this fix indicator object problem. , in similar manner can fix scorechoice object problem.
