path helper problem

Reported by Alexey Poimtsev | December 7th, 2010 @ 09:01 PM

Hi,
i'm expecting some problem with path helpers. Let me explain. I have some resource "issues" in my routes and would like to use helper with parameter issue_path("something"). Everything works fine if parameter does not contain dot(.) symbol, but for issue_path("some.thing") it will cause error like

ActionController::RoutingError in Issues#index

Showing /Users/alec/Documents/Projects/prj/app/views/issues/_issue.html.haml where line #30 raised:

No route matches {:controller=>"issues", :id=>"some.thing", :action=>"show"}

I don't think that it is a bug. I think there is a reason why you can't use dots.

If you are interested here is a regexp for such route:
```
/\A\/issues\/([^\/.?]+)(?:\.([^\/.?]+))?\Z/
```
Here are segments (for better understanding) for this route:
```
segments: ["/issues/", /(?<id>\A[^/.?]+\Z)/, [".", /(?<format>\A[^/.?]+\Z)/]]
```
I think you can't use dots because of format segment but i'm not sure, any ideas why dot is not allowed?

Yes, of course '.' is not allowed because it is separator for format.

ok, but sometimes we need to send '.' in path, what about encode/escape dot symbol?

- Importance changed from “” to “Low”
In routes mention :format => false and then use your regex and then dot will be allowed.
