ruby on rails - How do I set the ID in a link_to tag in haml? -


i've tried 

= link_to 'foo', :action => 'bar', :id => 'foobar'

but id seems modify href, resulting in 

<a href="controller/foobar/bar">foo</a>

how set id correctly? can explain me why :id modifying href can understand what's going on behind scenes?

you have put :action => 'bar' inside hash. 

= link_to 'foo', { :action => 'bar' }, :id => 'foobar'

there example in docs put example same problem:

classes , ids css easy produce:

link_to "articles", articles_path, :id => "news", :class => "article" # => <a href="/articles" class="article" id="news">articles</a>

be careful when using older argument style, literal hash needed:

link_to "articles", { :controller => "articles" }, :id => "news",      :class => "article" # => <a href="/articles" class="article" id="news">articles</a>

leaving hash off gives wrong link:

link_to "wrong!", :controller => "articles", :id => "news", :class => "article" # => <a href="/articles/index/news?class=article">wrong!</a>

this why it's better use new argument style, alias routes, more calling controllers , actions explicitly.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
