问题描述
我的 admin.py 中有一个带有以下类的 django 应用:
I have a django app with the following class in my admin.py:
class SoftwareVersionAdmin(ModelAdmin):
fields = ("product", "version_number", "description",
"media", "relative_url", "current_version")
list_display = ["product", "version_number", "size",
"current_version", "number_of_clients", "percent_of_clients"]
list_display_links = ("version_number",)
list_filter = ['product',]
我希望将这些文件用于添加页面，但将不同的字段用于更改页面.我该怎么做?
I want to have these fileds for add page but different fields for change page. How can I do that?
推荐答案
先看看ModelAdmin类的get_form和get_formsets方法的源码位于django.contrib.admin.options.py.您可以覆盖这些方法并使用 kwargs 来获得您想要的行为.例如:
First have a look at source of ModelAdmin class' get_form and get_formsets methods located in django.contrib.admin.options.py. You can override those methods and use kwargs to get the behavior you want. For example:
class SoftwareVersionAdmin(ModelAdmin):
def get_form(self, request, obj=None, **kwargs):
# Proper kwargs are form, fields, exclude, formfield_callback
if obj: # obj is not None, so this is a change page
kwargs['exclude'] = ['foo', 'bar',]
else: # obj is None, so this is an add page
kwargs['fields'] = ['foo',]
return super(SoftwareVersionAdmin, self).get_form(request, obj, **kwargs)
