文件存在,但显示404,如图:
/blog\source\_posts\yii404.png)
http://localhost:8081/yii2/sport_equipment/backend/web/index.php?r=audit_equipment%2Findex这是最后正确的路由,最开始试了audit_Equipment,auditEquipment,甚至还有audit-Equipment,文件就在那儿,咋就404呢?最后试出来,得用小写字母——“audit_equipment”,其实具体原理我也不懂。另外补充:Model的命名,只能是字母或写划线:“Only word characters and backslashes are allowed.”
显示数据库中的视图
在访问http://localhost:8081/yii2/sport_equipment/frontend/web/时,报错:
Invalid Configuration – yii\base\InvalidConfigException
The ‘label’ option is required.
我想做成:当前用户为游客时,不显示vborrow,当前用户登录后,vborrow才显示出来,可以点击,尝试之后,代码如下:
Path: frontend\views\layouts\main.php

因为视图没有主键,所以无法用gii生成CURD,所以复制了其他数据表的控制器和视图文件,在上边作了修改。
