Can't create a new file about projectile-rails HOT 9 CLOSED

As far as I know C-c C-r V is not meant to create views but to find existing ones. You are supposed to use the classic C-x C-f to create new files.

That said, maybe this could be improved.

@Silex Yes, actually, I checked the source code and tried to improve it before I asked this issue.
It seems have the code to use find-file. but the condition is a littlle kind of weird. I can't understand what it does. So I hope someone can improve the code.

C-c C-r V tries to be smart - if no corresponding files exists it will present the user the list of files in the corredponding dir to choose from. So if you're completion system allows to input a non-existant file and create a new buffer for it it means that C-c C-r V can create new files.

I see the bug I'll try to kill it.

@asok Seems the fix still does not work.
I tested on my Emacs, it will open dired, instead of create a new file. (Maybe I mis-understand? this is the normal behavior?)
I tried to use edebug to debug,
but have not found wrong. And I don't know how to dig deeper.

@stardiviner it will open the dired buffer because your completion system does not allow inputting arbitrary value. Try using ido (setq projectile-completion-system 'ido).
This is far from perfect but I don't know how to solve it. Maybe some message in mini-buffer would be explanatory.

@asok I see, I will open an issue on helm to see whether helm can support inputting arbitrary value feature. Thanks for your improvement.

@asok I found Helm has a source called helm-source-buffer-not-found, I will check it out to see whether can use that.

@stardiviner there is an option to helm :must-match 'confirm option, and projectile is using it. And even if I eval (helm-comp-read "Choose: " '("a" "b") :must-match 'confirm) and then I input "c" and confirm the "c" is returned.
But when I eval (helm-comp-read "Choose: " '("a" "b") :must-match 'confirm :candidates-in-buffer t) an empty string is returned.
This way helm-comp-read is run in projectile. Look here.

I tried to disable :candidates-in-buffer t in projectile-completing-read. projectile-rails still opens dired.

So helm did not support inputting arbitrary value?
