ruby on rails - Implement the gecoder gem in nested resource loop? -


i implemented geocoder gem based on tutorial on http://railscasts.com/episodes/273-geocoder

this part of house show view template

- @house.location.nearbys(20, {:order => :distance, :units => :km}).each |house|    %li     = link_to house.name, house_path     (#{city.distance.round(2)} km)

this show al other houses distance in km, works fine.

i showed on same house page cities of region house located, this: 

%ul.tags  - @region.cities.each |city|    %li= link_to city.name, country_region_city_path(@country, @region, city)

question: how can implement geocoder gem in @region.cities loop visitor can see on house page how many km drive house cities?

thanks...remco

geocoded objects should have distance_from method. @house should have method if follow ryan bates' tutorial.

check docs how use it: https://github.com/alexreisner/geocoder#location-aware-database-queries

you need ask @house it's distance city (within cities loop)

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...
