未定义：在revel应用程序启动时显示revel.LoadConfig

Question

I was following this tutorial on using Go + Revel + MongoDB. But as I starting the application, I got this error:

The Go code api-go/app/init.go does not compile: undefined: revel.LoadConfig

along with other errors as I look in the terminal.

ERROR 2016/10/18 17:15:06 build.go:108: # api-go/app
api-go/app/init.go:41: undefined: revel.LoadConfig
api-go/app/init.go:43: undefined: log in log.Fatalf

api-go/app/init.go:47: cannot assign to mongodb.DBNAME
api-go/app/init.go:48: undefined: mongodb in mongodb.CheckAndInitServiceConnection

I used Mac Sierra. What's wrong with my application?

As I see your errors I think you should add in your file "init.go" this code

     import ( 
        "log"
        "github.com/revel/revel" 
        “myapp/app/models/mongodb”
      ) 

This just under the first line of your init.go whitch contain "package"

Next in your code you have to replace:

   revel.LoadConfig("app.conf")

by

   revel.config.LoadContext("app.conf",ConfPaths)

where confPaths is the string path to your conf file. In your case it can be:

    ConfPaths := "conf/"

or

    ConfPaths := ""
