Basic Example of using Beegae

[salmosri]

Hi,

I am currently finding it a little difficult to get a hello world using beegae. There doesn't seem to be any documentation on here about usage of this?

Currently I have attempted the following:

salmosri@springs:~/Workspace/go/src/hellobeegae$ go get github.com/astaxie/beegae
package appengine: unrecognized import path "appengine"

This does seem to import the beegae library to the correct place (the error/warning could be resolved I hope?)

Created a Project Folder called hellobeegae and added the following

app.yaml

application: hellobeegae
version: 1
runtime: go
api_version: go1

handlers:
- url: /.*
  script: _go_app

What to do next is a little unclear? Can you point to any documentation to get this up and running?

Unsuccessful attempts:

1. Create a new bee project

salmosri@springs:~/Workspace/go/src$ bee new hellobeegae

Edit the main.go to change the import from beego to beegae

package main

import (
    "hellobeegae/routers"
    "github.com/astaxie/beegae"
)

func main() {
    beego.Run()
}

Edit the default.go to change the import from beego to beegae

package controllers

import (
    "github.com/astaxie/beegae"
)

type MainController struct {
    beego.Controller
}

func (c *MainController) Get() {
    c.Data["Website"] = "beego.me"
    c.Data["Email"] = "astaxie@gmail.com"
    c.TplNames = "index.tpl"
}

Edit the router.go to change the import from beego to beegae

package routers

import (
    "hellobeegae/controllers"
    "github.com/astaxie/beegae"
)

func init() {
    beego.Router("/", &controllers.MainController{})
}

Then executing the app with goapp serve

Any advice on resolving this?

Two things:

1. When you fetch the repository, use goapp get as this will include the appengine package
2. This is an issue with how the SDK is setup. Try creating a folder in your app root called main and move ONLY the views folder, the app.yaml file, and the main.go files. Keep everything else the same and try compiling then. Alternatively, use relative imports instead of full-path imports (not desirable as it goes against idiomatic Go but it will work)

Both of these are less of beegae specific questions but rather a lack of understanding on how to use the AppEngine go tools (mostly because they lack any decent documentation). I guess most users of beegae are familiar with these sort of caveats and how to use the tools which is why this sort of documentation was never written.

I'll be sure to put your write-up (with some modification) in a future release. There's also the "examples" directory that you can take a look at on how to structure your beegae code!

FYI - I updated beegae and added parts into the readme on how to get started. I hope this helps!
