I need to filter employees from same company as current user in forms.py.
But the solution I found, work only for single Formsets.
If I try to pass the request.user with modelformset_factory to generate a multiple formset, I get the following Error:
'MassnahmeForm' object has no attribute '__name__'
What can i Do?
Best regards
Bostjan
views.py:
frm = MassnahmeForm(user=request.user)
mformset = modelformset_factory(Massnahmen, form=frm, extra=mn.count())
forms.py:
class MassnahmeForm(forms.ModelForm):
id = forms.IntegerField(widget=forms.HiddenInput())
pdca = forms.IntegerField(widget=forms.HiddenInput())
status = forms.IntegerField(widget=forms.HiddenInput())
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user', None)
print(self.user)
super(MassnahmeForm, self).__init__(*args, **kwargs)
class Meta:
model = Massnahmen
widgets = {
'massnahme': forms.Textarea(attrs={'onkeyup':'resizeTextarea()', 'rows': 3, 'style': 'margin: -5px;'
'width: 100%;'
'height: 100%;'}),
'umsetzer': forms.Select(choices=users, attrs={'style': 'width: 100%;'
'margin: 0px;'
'font-size: 100%;'
'padding: 0px'}),
'termin': forms.DateInput(attrs={'class': 'flatpickr flatpickr-input active',
'placeholder': 'Termin',
'readonly': 'readonly',
'style': 'width: 100%;'
'margin: 0px;'
'font-size: 100%;'
'padding: 0px'}),
}
fields = ('massnahme','umsetzer','termin','status')
You need use the Class of the form in the modelformset_factory, not one instance. Next, you can make use of the form_kwargs parameter in the Formset.
MassnahmeFormSet = modelformset_factory(
model = Massnahme,
form = MassnahmeForm,
extra = mn.count()
)
formset = MassnahmeFormSet(form_kwargs={'user': request.user})

I use Django formset factory and update view don't fill subform with
raw SQL query and return 'RawQuerySet' object has no attribute 'ordered'
error.
object query set fine but raw SQL query return this error.
'''python
formset = modelformset_factory(model=GiftVoucherSub,

fixed by adding extra field to forms.py and views queryset with django object.
passanger name with autocomplete.

Hi (sorry for my bad english), i'm trying to show a form using a number input instead a select in a FK Relation on django model, but i cant make it.
The thing is that i need to fill the ID of the product manually writing the id in a input box, but django automatically makes the select form with all the products!
this is what i have in forms.py
class PurchaseForm(forms.ModelForm):
class Meta:
model = Purchase
fields = [
'date',
'supplier',
'warehouse',
]
widgets = {
'date': forms.DateInput(attrs={
'type': 'date',
}),
}
class PurchaseItemForm(forms.ModelForm):
class Meta:
model = PurchaseItem
fields = [
'product',
'quantity',
'net_purchase_price',
'sell_price',
]
widgets = {
'product': forms.NumberInput(),
}
PurchaseFormSet = inlineformset_factory(
Purchase,
PurchaseItem,
fields='__all__',
extra = 10,
)
this is my view
class PruchaseCreateView(CreateView):
template_name = 'purchases/create_purchase.html'
form_class = PurchaseForm
def get_context_data(self, **kwargs):
context = super(PruchaseCreateView, self).get_context_data(**kwargs)
if self.request.POST:
context['formset'] = PurchaseFormSet(self.request.POST)
else:
context['formset'] = PurchaseFormSet()
return context
def form_valid(self, form):
context = self.get_context_data()
formset = context['formset']
if formset.is_valid():
self.object = form.save()
formset.instance = self.object
formset.save()
return redirect(self.object.get_absolute_url())
else:
return self.render_to_response(self.get_context_data(form=form))
i try with the widget NumberInput but nothing!!! any idea?
You need to include the custom form when you call inlineformset_factory:
PurchaseFormSet = inlineformset_factory(
Purchase,
PurchaseItem,
form=PurchaseItemForm
fields='__all__',
extra = 10,
)
My view passes an id to my form. This id is a foreign key from another table. I am not able to save the id in the database table.
(id : voucher_id, table in which i am saving the form : TmpPlInvoicedet)
What i want to do
Send voucher_id from (View) to ---> TmpFormDetForm (Form) ---> TmpPlInvoicedet (DB)
Trying to get instance from the table 'TmpPlInvoice' (which has voucher_id as PK) and save it in the form gives me
DoesNotExist at /new/ TmpPlInvoice matching query does not exist
What am i doing wrong?

else:
voucher_id = str(int(max(temp_vid)) + 1).zfill(4)

You seem to be creating a new invoice ID and then, in your form, attempting to get the invoice matching that ID. But that invoice doesn't exist yet, of course, because you haven't created it.
You might want to use get_or_create to ensure that the invoice is created if it doesn't exist.
How to set first default rows/values in django admin's inline?
class Employee(models.Model):
username = models.CharField(_('Username'), max_length=150, null=False, blank=False)
email = models.CharField(_('Email'), max_length=150, null=False, blank=False)
class Details(models.Model):
employee = models.ForeignKey(Employee, verbose_name=_('Employee'), blank=False, null=False)
label = models.CharField(_('Label'), max_length=150, null=False, blank=False)
value = models.CharField(_('Value'), max_length=150, null=False, blank=False)
class DetailsFormset(forms.models.BaseInlineFormSet):
def __init__(self, *args, **kwargs):
self.initial = [
{ 'label': 'first name'},
{'label': 'last name'},
{'label': 'job',}]
super(DetailsFormset, self).__init__(*args, **kwargs)
class DetailsInline(admin.TabularInline):
model = Details
formset = DetailsFormset
fieldsets = [
['', {'fields': ['employee', 'label', 'value']}]
]
class EmployeeAdmin(admin.ModelAdmin):
inlines = [DetailsInline]
but this row doesn't work
self.initial = [
{ 'label': 'first name'},
{'label': 'last name'},
{'label': 'job',}]
How do I set default values using django admin?
from django.utils.functional import curry
class DetailsInline(admin.TabularInline):
model = Details
formset = DetailsFormset
extra = 3
def get_formset(self, request, obj=None, **kwargs):
initial = []
if request.method == "GET":
initial.append({
'label': 'first name',
})
formset = super(DetailsInline, self).get_formset(request, obj, **kwargs)
formset.__init__ = curry(formset.__init__, initial=initial)
return formset
From here: Pre-populate an inline FormSet?
If what you need is to define default values for the new forms that are created you can redefine the empty_form property of a InlineFormSet:
class MyDefaultFormSet(django.forms.models.BaseInlineFormSet):
#property
def empty_form(self):
form = super(MyDefaultFormSet, self).empty_form
# you can access self.instance to get the model parent object
form.fields['label'].initial = 'first name'
# ...
return form
class DetailsInline(admin.TabularInline):
formset = MyDefaultFormSet
Now, every time you add a new form it contains the initial data you provided it with. I've tested this on django 1.5.
I tried many suggestions from Stackoverflow (Django=4.x), not working for me.
Here is what I did.
class MilestoneFormSet(forms.models.BaseInlineFormSet):
model = Milestone
def __init__(self, *args, **kwargs):
super(MilestoneFormSet, self).__init__(*args, **kwargs)
if not self.instance.pk:
self.initial = [
{'stage': '1.Plan', 'description': 'Requirements gathering', },
{'stage': '2.Define', 'description': 'Validate requirement', },
]
class MilestoneInline(admin.TabularInline):
model = Milestone
formset = MilestoneFormSet
def get_extra(self, request, obj=None, **kwargs):
extra = 0 #default 0
if not obj: #new create only
extra = 2 #2 records defined in __init__
return extra
I hope this works for everyone.
To provide a static default for all instances in the inline, I found a simpler solution that just sets it in a form:
class DetailsForm(django_forms.ModelForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['label'] = 'first_name'
class DetailsInline(admin.TabularInline):
form = DetailsForm
# ...
I think this doesn't work for the OP's particular case because each form has a different value for the 'label' field, but I hope it can be useful for anyone coming to this page in the future.
