问题
I try to make one field in django admin's fieldsets to show only certain data, but according to django document, only an example of list_display
is shown to be able to customize. I tried the similar approach on fieldsets
like the following:
In models.py:
def ports_with_same_scanner(self):
return PortList.objects.filter(scanner=self.scanner)
ports_with_same_scanner.short_description = 'port_lists'
In admin.py, this won't work:
fieldsets = (
('Scan Template', {
'fields': ( ('name', 'scanner', 'ports_with_same_scanner',), 'comment', ('in_use',
'fc_growing', 'nc_growing'), 'nvt_prefs')
}),
)
However, if I do this:
list_display = ('name', 'scanner', 'ports_with_same_scanner', 'comment', 'in_use', 'fc_growing', 'nc_growing', 'nvt_prefs')
the ports_with_same_scanner
works just fine. The problem is that I don't want to change my display from fieldsets
to list_display
, I wonder how can I achieve the same functionality. Thanks.
回答1:
Would it work to apply the filter at the model level? If so you can use the limit_choices_to attribute on the model's ForeignKeyField
.
Alternatively you could override the formfield_for_foreignkey attribute of the modelAdmin class.
Something like -
class YourModelAdmin(admin.ModelAdmin):
def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == "ports_with_same_scanner":
kwargs["queryset"] = PortList.objects.filter(scanner=self.scanner)
return super(YourModelAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)
(Apologies if I've misunderstood the question)

I don't know if real problem at past ... I always using simple approach - to adding a name of method to the readonly_fields = ()
Example:
models.py
class My(models.Model):
def custom_name(self):
return 'test'
custom_name.allow_tags = False
custom_name.short_description = 'custom_name'
admin.py
class MyAdmin(admin.ModelAdmin):
fieldsets = (
(None, {
'fields': ('custom_name', )
}),
)
readonly_fields = ('custom_name', )
It must be working Django >=1.7 It seems the approach can be apply to early version of Django^ but I don't testing
