django: Override get_Form inlines

Question

I want to override the get_form in a tabular admin in order to filter by current user. The thing is that I'm getting a error:

 object has no attribute 'current_user'

Admin.py

class InvoiceDetail(admin.TabularAdmin):
    form = InvoiceDetailForm
    model = fa_invoice_lines

    def get_form(self, request, obj=None, **kwargs):
        form = super(InvoiceDetail, self).get_form(request, obj, **kwargs)
        form.current_user = request.user
        return form

class Invoice(admin.ModelAdmin)
    form = InvoiceForm
    inlines =   [InvoiceDetail,]

Form.py

class InvoiceDetailForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(InvoiceDetailForm, self).__init__(*args, **kwargs)
        self.fields['item'].queryset = fa_items.objects.filter(tenant=self.current_user)

    class Meta:
        model = fa_invoice_lines

I have used the same strategy in not inlines and it works It seems is not calling the get_form

I see that "some help" is given but I also understand that it is not appreciated or even accepted. — raratiru, Feb 03 '17 at 14:39

Inspired from the docs, I have implemented the following solution:

class Invoice(admin.ModelAdmin)
    form = InvoiceForm
    inlines =   [InvoiceDetail,]

def get_formsets_with_inlines(self, request, obj=None):
    for inline in self.get_inline_instances(request, obj):
        inline.form.current_user = request.user
        yield inline.get_formset(request, obj), inline

admin.TabularAdmin does not have a get_form method. The get_form function you defined is never being called.

You might want to look into get_formset method.
