create a image then show in the page not working in ruby on rails -


i use "gruff" draw graph database table

the last step of function create image in folder

bar_chart.write("/home/lawyer/capistrano/current/app/assets/images/graph/lawfirm_#{@lawyer.id}.png")

and in show page :it use image show in div

-if file.exists?("/home/lawyer/capistrano/current/app/assets/images/graph/lawfirm_#    {@lawyer.id}.png") = image_tag("graph/lawfirm_#{@lawyer.id}.png")

it works fine in local host .but in production image not shown .

in console log shows error message:

started "/assets/graph/lawfirm_2673.png" 217.86.186.128 @ 2013-05-15 10:19:04 +0200 served asset /graph/lawfirm_2673.png - 404 not found (3ms)  actioncontroller::routingerror (no route matches [get] "/assets/graph/lawfirm_2673.png"):

but work. can show image.

at first function of draw graph in same controller , same method "index", hope draw graph first show image. add 

before_filter :draw_graph

and move draw graph function in method "draw_graph"

but still same problem

i think because you're generating images in app? if generating them within app , storing them, not work in production if deploy services heroku. need use amazon s3 hold images in production.

this post describes similar problem.

there's gem install aws , decent tutorials this (setup paperclip, same principles apply).
