Python Django admin中添加和更改视图的不同表单字段
我想在Django admin中为添加和更改视图显示不同的表单字段 如果是Python Django admin中添加和更改视图的不同表单字段,python,django,Python,Django,我想在Django admin中为添加和更改视图显示不同的表单字段 如果是add,则显示表单字段file\u upload;如果是change,则显示模型字段cname和mname 来自admin.py的代码 class couplingAdmin(admin.ModelAdmin): list_display = ('cname','mname') form = CouplingUploadForm #upload_file is here def get_form(
add
,则显示表单字段file\u upload
;如果是change
,则显示模型字段cname
和mname
来自admin.py的代码
class couplingAdmin(admin.ModelAdmin):
list_display = ('cname','mname')
form = CouplingUploadForm #upload_file is here
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'] = ['upload_file',]
else: # obj is None, so this is an add page
kwargs['exclude'] = ['cname','mname',]
return super(couplingAdmin, self).get_form(request, obj, **kwargs)
如果它是add
,那么就可以了,但是如果它是change
view,那么我会得到所有字段,比如cname、mname、upload\u file
请建议如何从“管理”中的“更改”视图中删除upload\u文件
非常感谢您的帮助。提前感谢。您可以覆盖ModelAdmin
中的和方法:
class CouplingAdmin(admin.ModelAdmin):
list_display = ('cname', 'mname')
form = CouplingUploadForm # upload_file is here
def add_view(self, request, extra_content=None):
self.exclude = ('cname', 'mname')
return super(CouplingAdmin, self).add_view(request)
def change_view(self, request, object_id, extra_content=None):
self.exclude = ('upload_file',)
return super(CouplingAdmin, self).change_view(request, object_id)
要使用完全不同的表单添加/更改,请执行以下操作:
类耦合管理员(admin.ModelAdmin):
列表显示=('cname','mname')
def get_表单(自我、请求、obj=None、更改=None、**kwargs):
如果不是obj:
#仅在添加新记录时使用其他表单
回程联轴节
return super().get_表单(请求,obj=obj,change=change,**kwargs)
更改视图仍显示上载文件
字段。是不是因为我以前叫过form=CouplingUploadForm
class couplingAdmin(admin.ModelAdmin):
list_display = ('cname','mname')
def get_fields(self, request, obj=None):
if obj:
fields=('upload_file',)
else:
fields =('cname','mname')
return fields
