Question

我想覆盖表格管理员中的get_form，以便按当前用户进行过滤。问题是我收到了错误：

 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

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get_form函数永远不会被调用。

您可能需要查看get_formset方法。

https://docs.djangoproject.com/en/1.6/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_formsets

Answer 2

受到the docs的启发，我实施了以下解决方案：

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

django：覆盖get_Form内联
