Question

my program displays information about items from the database when I just type their name.
It works fine for IDs and most names except when the name contains a dot.

match 'show/:name' => 'show#displayinfo'

In the controller I have:

@details = Description.where(:name => params[:name] ).first

Along with conditions on what to do if name was not found

When I type something like ../show/Ruby – it works fine
but ../show/a.b displays an empty page and no errors except this in the development log:

Processing by ShowController#displayinfo as 
Parameters: {"name"=>"a"}

If I type ../show/a this works as expected, no errors, no empty views.

Any way to solve this except renaming the items in the database?

Answer 1

From the manual

match 'show/:name' => 'show#displayinfo', :format => false

should do it.
