我能够将(跛脚)静态文本插入到更改表单管理页面,但我真的希望它使用当前正在编辑的对象的上下文!
例如,我想在MyObject更改表单上格式化一个URL,以包含来自ForeignKey连接对象(obj
)的ID作为链接。
我的管理对象:
class MyObjectChangeForm(forms.ModelForm):
class Meta:
model = MyObject
fields = ('field1', 'obj',)
class MyObjectAdmin(admin.ModelAdmin):
form = MyObjectChangeForm
list_display = ('field1', 'obj')
def render_change_form(self, request, context, *args, **kwargs):
self.change_form_template = 'admin/my_change_form.html'
extra = {'lame_static_text': "something static",}
context.update(extra)
return super(MyObjectAdmin, self).render_change_form(request,
context, *args, **kwargs)
我的模板templates/admin/my_change_form.html
:
{% extends "admin/change_form.html" %}
{% block form_top %}
{{ lame_static_text }}
<a href="http://example.com/abc/{{ adminform.data.obj.id }}?"/>View Website</a>
{% endblock %}
{{adminform.data.obj.id}}
电话显然不起作用,但我想要沿着这些方向做点什么。
如何将当前对象的动态上下文插入管理员更改表单?

class MyObjectAdmin(admin.ModelAdmin):
# A template for a very customized change view:
change_form_template = 'admin/my_change_form.html'
def get_dynamic_info(self):
# ...
pass
def change_view(self, request, object_id, form_url='', extra_context=None):
extra_context = extra_context or {}
extra_context['osm_data'] = self.get_dynamic_info()
return super(MyObjectAdmin, self).change_view(
request, object_id, form_url, extra_context=extra_context,
)

我相信您要寻找的魔术变量是“原始”变量,其中包含更改形式正在编辑的python对象:
<a href="http://example.com/abc/{{ original.id }}?"/>View Website</a>
