rails assets pipeline

this may take few iterations step through. first error heroku flags failed on /favicon.ico

2015-07-05t17:56:19.804219+00:00 heroku[router]: at=error code=h10 desc="app cra shed" method=get path="/favicon.ico" host=glacial-falls-7476.herokuapp.com reque st_id=091b3b97-bbab-4d13-b6a1-da24aa2b018b fwd="50.163.200.7" dyno= connect= ser vice= status=503 bytes= 

what tell there asset pipeline problem, because app should looking filename below, not original filename:

href="/assets/favicon-17897c732521afcc30d49410042fc687.ico"

the favicon filename should compiled asset name. there number of steps debug this:

1. did execute production rake prior deployment?

$bundle exec rake assets:precompile rails_env=production 

2. excellent, next step push app heroku deploy app blob assets compiled rails asset pipeline.

$heroku push 

if app crashes, please post updated heroku log. if runs, woohoo. problem.

3. so easy solution didn't work. , didn't compile .ico assets. means there's problem in config, it's not building app blob correctly.

aside there number of serious errors in new log.

webrick should not server running on heroku--that's red flag. know why webrick launching?

the ip looks incorrect.

rails 4.2.1 application starting in production on http://0.0.0.0:4674 

everything in block needs fixed , don't think it's going easy. pushing working app development heroku typically easy, don't know setting have throwing weeds. i'd @ gemfile, production,rb, application.rb differences there "development" versus "production"

i wish had one-line answer, don't. think there several deploy issues need worked, 1 @ time.

my advice scale down app, or start dummy test app , deploy in stages.

or maybe come along complete answer...
