Django管理员 - 如何保存内联？

Question

我需要重写管理中内联的保存方法。在保存照片时，我需要将用户ID添加到数据库列。我无法在模型中创建它，因为那里没有请求数据。我怎么能在管理员，以某种方式获得设置用户ID？

Answer 1

我相信上的ModelAdmin的save_formset方法是你应该用什么：

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

我是比较新的Django的（1.8），并使用上述倍率：

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到它，但是当用户输入2行时，它总是保存最后的cleared_data ['enum_value_en']。
