1.2.admin.py 设定

1.2.1.AccountAdmin呈现画面

记录每个月的结算情况，AccountAdmin下有SccountDetailInline(门店结账金额)与AccountDetailInline(结账金额)，记录该月份总营业额/手工费用与合作分店的营业额/手工费用。
第一个月的记录需从后台写入，接下来月份的空白资料则由上个月产生。

class SccountDetailInline(admin.TabularInline):
    model = SccountDetail
    fields = ['account', 'store', 'type', 'amount']

1.2.2.FeeDetailAdmin呈现画面

因手工费用明细是自动抛转，所以add/change/delete权限都是关闭的。

@admin.register(FeeDetail)
class FeeDetailAdmin(admin.ModelAdmin):
    list_display = ['id', 'feed', 'type', 'service_id', 'store', 'employee', 'amount']
    view_on_site = False

1.2.3.FeeCostAdmin呈现画面

记录每个月份合作门店该给员工多少手工费用(总额)，此处金额是每月结账时自动产生的，所以add/change/delete权限也都是关闭的。
