Beego: 运行bee run时会报routers/commentsRouter_xxx_controllers.go: too few values in struct initializer

[vegeta34]

出错的地方在routers/commentsRouter_xxx_controllers.go文件的beego.ControllerComments初始化处：
beego.ControllerComments{ "Post", /, []string{"post"}, nil})

查看了beego的源码，ControllerComments定义在beego/controller.go中：
type ControllerComments struct {
Method string
Router string
AllowHTTPMethods []string
Params []map[string]string
MethodParams []*param.MethodParam
}
这个定义中需要5个变量，而我的routers/commentsRouter_xxx_controllers.go中的beego.ControllerComments初始化时却只有4个变量
同时，routers/commentsRouter_xxx_controllers.go这个文件应该是自动生成的，想请问下这个问题怎么解决？

my bee tool version now is 1.8.4, I found no version newer than this.
And my beego version is 1.8.3
I have removed beego/bee and astaxie/beego, and then reinstalled them using:
go get github.com/astaxie/beego
go get github.com/beego/bee,
But nothing improved....

Hmm.. maybe you need to regenerate comments controller? Make some change in your controller file?

[eyalpost]

in beego 1.8.4 another parameter was added to ControllerComments. You can add nil to last item and then try to regenerate the source. Which version of beego did you upgrade from?

[vegeta34]

I'v no idea which version i used before...
You mean I add code in commentsRouter_xxx_controllers.go and commentsRouter_controllers.go?
Are these files not auto-generated?

[vegeta34]

And I tried to modify get to post in controller files, but no changes happend in commentsRouter_xxx_controllers.go

[eyalpost]

Yes, do it manually one time to make sure it compiles. Then go to your xxx controller file and do some minor change (so beego will detect it needs to regenerate)

After I add nil to last item in ControllerComments, it shows [parser.go:117] Invalid @Param format. Needs at least 4 parameters, stack shows below:
2017/05/21 15:58:45 [E] [parser.go:117] Invalid @Param format. Needs at least 4 parameters

It fixed after i modified comments of method in controller.
Now routers/comments_controller.go can be generated correctly, and it runs ok!
Thanks very much for help!

[qichengzx]

Is that not a bug？I got this error too.
I add "MethodParams: nil" to commentsRouter_controllers.go and it's was still error.
After I change controllers,commentsRouter_controllers has no changes

[astaxie]

@qichengzx please delete commentsRouter_controllers.go and generate again

[qichengzx]

@astaxie 删掉了，并没有重新生成，我再研究下。多谢。

[astaxie]

@qichengzx 路由没有自动生成？你是不是在dev模式？

[qichengzx]

@astaxie 不好意思刚看到。嗯，在dev模式。

[qichengzx]

我知道了是什么引发了这个问题，在以前的controller里的@param参数只有一个 “@Param body”。所以会报“[E] [parser.go:117] Invalid @Param format. Needs at least 4 parameters”

I know what caused this problem, the @param parameter in the previous controller only has a "@Param body". So will be reported "[E] [parser.go: 117] Invalid @Param format. Needs at least 4 parameters"
