ruby on rails - undefined method `each' for #<Comment:0x007f12ef55d0d0> -

-

I was working on the Blogger blogger on Rail Blogger:

and I'm at the point where I am correcting the action of the Blogger app's show.

Here's my controller: 

  Diff show @ articles = article. Fix (Param [: id]) @ comment = comment.new @ comments = comment. Address (Param [: id]) end


Here is my show view - (which is partially presenting my comments) < / P> `

My comments are partial here: articles-path => gt; 

  & lt; div & gt; & lt;% @ comments.each do | Comment | & Comment by: & lt; h4 & gt; & lt;% = comment Author_name% & gt; & lt; / h4 & gt; & lt; p class = "comment" & gt; & lt;% = comment.body% & gt; & lt; / p & gt; & lt;% end %>

My problem is that when I show all comments from comments model on the show page through each iterator in comments in comments A I am getting the error, then I get this error:

Undefined method `for each '& lt; note: 0x007f12ef55d0d0 & gt;

show action I do not see any problem with my example variables, and each method I wrote has proper syntax. Does anyone know what this error is?

Your error basically means that you expect an array of comments O, but only a note saying the way you find that only one object will return, not an array. You need to adjust the following line:

@comments = Comment.find (params [: id])

If your relationships are correct , You should be able to change it with something like this:

@comments = article.comments

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.

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.
