Go Google app engine - can't find template files

Question

I using Gin framework. At local development mode: goapp serve all works fine.

func init() {
    route := gin.Default()
    route.LoadHTMLGlob("../*/views/**/*.html")
    ...
}

But after deploy:

panic: html/template: pattern matches no files: ../*/views/**/*.html

OK. I try:

func init() {
    route := gin.Default()
    dir, _ := filepath.Abs(filepath.Dir(os.Args[0]))
    route.LoadHTMLGlob(dir + "/../*/views/**/*.html")
    ...
}

Same result.

I try fetch dir:

...
dir, err := filepath.Abs(filepath.Dir(os.Args[0]))
if err != nil {
    ...
}
c.String(http.StatusOK, "Dir: ", dir)

c.String(http.StatusOK, "\nOK")
res, err := filepath.Glob(dir + "/*")
c.String(http.StatusOK, fmt.Sprintf("%v | %v\n\n", res, err))

c.String(http.StatusOK, "Dirs:")
res, err = filepath.Glob(dir + "/**/*")
c.String(http.StatusOK, fmt.Sprintf("%v | %v", res, err))
...

Result:

Dir: %!(EXTRA string=/base/data/home/apps/tmp-LEIYJC/_ah) OK[/base/data/home/apps/tmp-LEIYJC/_ah/exe] |

Dirs:[] |

Ooops. What I done wrong?

UPD:

app.yaml

runtime: go
api_version: go1

handlers:
- url: /images
  static_dir: ../static/images

- url: /css
  static_dir: ../static/css

- url: /js
  static_dir: ../static/js

- url: /fonts
  static_dir: ../static/fonts

- url: /.*
  script: _go_app

I put app.yaml to subdirectory, cause without that another problem: [https://groups.google.com/forum/#!topic/google-appengine-go/dNhqV6PBqVc

Folder structure:

app/
    app.go
    app.yaml
static/
    ...
frontend/
controllers/
    UserController.go
    ...
models/
    UserModel.go
    ...
views/
        home/
            *.html
        user/
            *.html
        anotherfolder/
            *.html
backend/
controllers/
    MainController.go
    ...
models/
    SomeModel.go
    ...
views/
        main/
            *.html
        anotherfolder/
            *.html
...

Answer 1

I found next solution.

I reorginize structure:

app/
    static/
        ...
    frontend/
        views/
           home/
               *.html
           user/
               *.html
           anotherfolder/
               *.html
    backend/
        views/
            main/
                *.html
            anotherfolder/
                *.html
    app.go
    app.yaml

frontend/
    controllers/
        UserController.go
        ...
    models/
        UserModel.go
        ...
backend/
    controllers/
        MainController.go
    ...
    models/
        SomeModel.go
    ...
...

Change:

app.yaml

runtime: go
api_version: go1

handlers:
- url: /images
  static_dir: static/images

- url: /css
  static_dir: static/css

- url: /js
  static_dir: static/js

- url: /fonts
  static_dir: static/fonts

- url: /.*
  script: _go_app

It's really strange ecision GAE. I can't put app.yaml to root directory for application because I got panic message for duplication import. And I can't put templates to root directory because that not under scope, only at directory parent to app.yaml

Answer 2

If I'm not mistaken all of your directories should live within the root directory where your app.yaml exists. So you would want something like this. Also, when you want your application to access a static file directory you need to add application_readable: true to that directories definition. See the next example down. Hope this helps.

app/
    app.go
    app.yaml
    static/
        ...
    frontend/views/
        home/
        *.html
    anotherfolder/
        *.html

Example Directory Definition:

- url: /s
  static_dir: s/
  application_readable: true
