通过将verbose_name和verbose_name_plural添加到MeasurementInline，我设法更改了文本（在本例中以小写“m”开头）：

class MeasurementInline(InlineModelAdmin):
    model = Measurement
    extra = 0
    verbose_name = 'measurement'
    verbose_name_plural = 'measurements'

我不喜欢这个解决方案。所以对于每一个想改变整个文本“添加另一个{obj_verbose_name}”的人，这里是我想到的

class InlineAdminFormSetOnlyAddTextInAddInline(helpers.InlineAdminFormSet):
def inline_formset_data(self):
    return json.dumps({
        'name': '#%s' % self.formset.prefix,
        'options': {
            'prefix': self.formset.prefix,
            'addText': gettext('Add'),
            'deleteText': gettext('Remove'),
        }
    })

在这里我实现了BaseAdmin类，您需要覆盖 get_inline_formsets -方法
就像这样：

def get_inline_formsets(self, request, formsets, inline_instances, obj=None):

      can_edit_parent = self.has_change_permission(request, obj) if obj else self.has_add_permission(request)
    inline_admin_formsets = []
    for inline, formset in zip(inline_instances, formsets):
        fieldsets = list(inline.get_fieldsets(request, obj))
        readonly = list(inline.get_readonly_fields(request, obj))
        if can_edit_parent:
            has_add_permission = inline.has_add_permission(request, obj)
            has_change_permission = inline.has_change_permission(request, obj)
            has_delete_permission = inline.has_delete_permission(request, obj)
        else:
            # Disable all edit-permissions, and overide formset settings.
            has_add_permission = has_change_permission = has_delete_permission = False
            formset.extra = formset.max_num = 0
        has_view_permission = inline.has_view_permission(request, obj)
        prepopulated = dict(inline.get_prepopulated_fields(request, obj))
        inline_admin_formset = InlineAdminFormSetOnlyAddTextInAddInline(
            inline, formset, fieldsets, prepopulated, readonly, model_admin=self,
            has_add_permission=has_add_permission, has_change_permission=has_change_permission,
            has_delete_permission=has_delete_permission, has_view_permission=has_view_permission,
        )
        inline_admin_formsets.append(inline_admin_formset)

或类似于：

def get_inline_formsets(self, request, formsets, inline_instances, obj=None):
   formsets_ = super().get_inline_formsets(request, formsets, inline_instances, obj)
   for formset_obj in formsets_:
      formset_obj.__class__ = InlineAdminFormSetOnlyAddTextInAddInline
   return formsets_

如果有人知道更好的解决办法，我很高兴听到它。
