ruby on rails - Can I Render A Layout Directly From routes.rb, Without A Controller? -

-

I would like to set a pair of style guides for the administrator of a website and the public sections.

Each will need its own layout, which will contain a mixture of static HTML and partially calls to make a call (no such static page will not cut it). There is no need for controller (s) to serve these pages and I do not want that which is effectively development-only content, it disrupts the rest of the code. I hope to think that there is no way to render the layout directly.

Disclaimer: I appreciate it that I should never do sometimes and I know why reasoning is the money. This idea is not good. I am interested in whether it is possible.

Is there any layout with no control directly from routes.rb ?

For some strange / stupid reason I wanted to render a blank JS file , And writing a controller felt too much for this kind of hack. Thanks for the reply @inikilabs, I used this 3 liner: 

  get 'analytics / some_file.js', for: - & gt; (Env) [200, {'Content-type' = & gt; 'App / javascript'}, [']] end

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here. Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program. Any idea how can I get the username that started the program? ! Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...

For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
