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

Answer 1

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.
