ruby on rails - What's the best way to store images for a carousel? -


i'm using ruby on rails. i'll have 2 carousels on landing page, , want know best way store , display these images:

option one

put images in assets/images , show them in carousel. if way, can loop through images in folder or i'll have specify each 1 of files?

option two

create model image column , loop through images have specific attribute?

other three

something else

thanks!

i'd recommend not place them directly in assets/images directory because add application-specific images app @ point won't want in carousel. folder app/assets/images/carousel, example, allows more determine images belong in carousel.

in controller, add following:

@images = dir.glob("app/assets/images/carousel/*.{gif,jpg,png}")

then, in view, add following (assuming erb)

<% @images.each |image| %>    <%= image_tag "carousel/#{image.split('/').last}" %> <% end %>

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...
