django - Django admin - 如何保存内联？

Question

我需要在管理员中覆盖内联的保存方法。保存照片时，我需要将用户 ID 添加到 DB 列。我无法在模型中制作它，因为那里没有请求数据。我怎样才能在管理员中做到这一点，以某种方式获得 nad set user id？

Answer 1

我相信 ModelAdmin 上的 save_formset 方法是您应该使用的：

class ArticleAdmin(admin.ModelAdmin):
    def save_formset(self, request, form, formset, change):
        instances = formset.save(commit=False)
        for instance in instances:
            instance.user = request.user
            instance.save()
        formset.save_m2m()

Answer 2

我对 django (1.8) 比较陌生，并且使用了上面的覆盖：

def save_formset(self, request, form, formset, change):
    instances = formset.save(commit=False)  # gets instance from memory and add to it before saving it
    for obj in formset.deleted_objects:
        obj.delete()
    for instance in instances:
        for form in formset:  # cleaned_data is only available on the form, so you have to iterate over formset
            instance.modified_by = request.user
            instance.created_by = request.user
            instance.lowercase_enum_value_en = form.cleaned_data['enum_value_en'].lower()
            instance.save()
    formset.save_m2m()

即在保存实例和表单之前添加它，但是当用户输入2行时，它总是保存最后一个cleaned_data ['enum_value_en']。
