django：覆盖 get_Form 内联

Question

我想覆盖get_form表格管理中的 以便按当前用户进行过滤。问题是我收到一个错误：

 object has no attribute 'current_user'

• 管理员.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,]
  

• 表格.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
  

我在非内联中使用了相同的策略并且它有效似乎没有调用get_form

Answer 1

admin.TabularAdmin没有get_form方法。您定义的函数get_form永远不会被调用。

您可能想研究一下get_formset方法。

Answer 2

受文档的启发，我实现了以下解决方案：

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
