Changes made in rails app /public directory not reflecting on server - ruby-on-rails

I have an replica of the live app that is deployed on the server. I have made some changes: like inserted 2 css and js files in /public directory that serves my assets and included in the views where they are required .It is working fine on my Local machine but when I pushed the changes to the server it is not reflecting over there. I am Using Nginx and I have tried restarting it as well but it didn't help either.
As I am new to NGINX and the App is deployed on a centos I dont know how it works.
I already have precompiled assets, So I don't know how to make it run. I have tried
Clearing the cache from tmp directory but didn't work.
I have set my
config.serve_static_assets = false
in my production.rb and tried restarting but didn't work either
Any help ??

Your views are cached in webserver workers. Have you restarted your web workers?

Loading webpacker assets in production

I'm trying to deploy to production (on a local machine) a Rails 5.2 app which uses webpacker for assets managemnet (I have totally replaced the assets pipeline).
Everything seems ok: as part of my deployment process I run the webpacker:compile task and both JS and CSS are compiled in the public/packs folder.
However, the assets aren't loaded from the app even if they are correctly linked.
Am I missing anything here?
I have tried to load via browser other files in the /public folder (i.e. robots.txt) but they are not availble neither. I get "The page you were looking for doesn't exist." error message.
In production by default rails expects to be behind a reverse proxy server like nginx that will serve all static files from public more efficiently.
Also for low loads the built-in file server can be enabled as a quick-fix, in production.rb:
config.public_file_server.enabled = true

rails 4.2 capistrano 3 Ubuntu nginx puma, getting routing error/no assets shows up

After following this tutorial, I tried was able to set up a rails application on an ec2 Ubuntu instance, running nginx web server and puma app server, deployed with capistrano 3. However, none of my assets are showing up, and I'm getting routing errors for basic functions of the Devise gem such as logging out. The chrome dev tool console shows 404 errors for the compiled application.css and application.js files.
I think the assets are there because if I ssh into the instance and go to the folder where my app is, I can see a bunch of files under public/assets. Also, if I check the capistrano logs, I can find the line bundle exec rake assets:precompile, and the status for that is successful. I tried things like going into the production.rb file and changing config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present? to config.serve_static_files = true
but still no assets. I think the biggest suspect is that there is some sort of routing error, because I don't really understand how web servers, app servers, and aws instances interact with each other. Could anyone point me in the right direction on debugging this? If you need to see a specific config file please comment below.
Ok it turns out all I had to do is copy the secrets.yml from the local repo for my app to the shared folder that is in [my_app_name]/shared/config. So my app didn't know where to look for the secret key base.
Although I'm still confused on why not having the secret.yml would prevent assets from served...

Rails Openshift Hot Deploy assets not served

i have a Rails application deployed on Openshift. I added marker for hot deploing and hot deploying itself works fine, but during the time application is hot deployed css and js files are not served. When hot deployment ends these files work fine again. I also use Bootstrap and Sass in this application (gem 'bootstrap-sass'). Do you have any idea why this happens?
The files are being served by Apache via the Passenger module. The files are being replaced "in place" which causes them to be removed/rebuilt, which is causing them to not be served during that time, and since they are static assets, they are not stored in memory. Unfortunately there is currently no way to make hot deploy work fully with Rails to keep the site 100% working while it is deployed.
One solution is to have your assets in a separate running project, since there is no easy way to have them available as all times as #developercorey explains..
It's probably not the best solution, but would be a simple patch-solution which is not tightly coupled to one particular hosting platform.
I fixed this issue, and it works now. I will explain what I did, maybe it will help somebody.
Basically there is need to precompile your assets locally, and commit and push them. This is done byrake assets:precompile RAILS_ENV=production
But there is a gotcha!!! Locally precompiled assets doesn't match those that are generated on Openshift. How is this possible? There is a bug on Openshift, that assets are generated on production with RAILS_ENV=development :/ More info here:
https://github.com/openshift/origin-community-cartridges/issues/8
so there is need to add environmental variable on your application:
rhc set-env RAILS_ENV=production -a app_name
then generated assets match.
So after fixing it, when during changes to assets, we need to precompile them again. And to make them work during hot deploying there is need to have both old precompiled assets and new precompiled assets in repo. For example:
If you have old file:
application-10770925dc8abd4ceab34119af4032163cc5a94f3523d60d321f33a999171d58.cssand new precoimpiled file:
application-82f6fca47056cbda52cb32086051f031b880e2630a137f0e41e96cb2eef923ee.css
they both have to be in repository. During hot deploying old asset is still referenced, so it has to be in repository. After hot deploying ends, new asset is referenced. In the next commit and push old asset may be removed.
So basically this issue is fixed for me, and hot deploying works fine now.

Pushing RoR app to Heroku, files in /public are missing

Let me start by saying I am using Ruby 2.0.0 and Rails 4.1.1
I've worked my way through the Treehouse basic RoR course; ending in a very basic version of Twitter. I have the application running just fine on my local install, but when I pushed it to Heroku it seems to be missing the files in the /public directory; namely the /assets css and javascript.
I've precompiled my assets as instructed, and verified that they area indeed showing up on my GitHub remote that is using the same branch. I was told that Heroku will not compile your assets for you.
All my routes and HTML is displaying just fine, but I cannot pull any of the files that live in the /public directory (404.html, 500.html, etc)
It feels to me like it is a permissions issue or something with the /public directory, but I haven't found a way to actually browse what files are on my Heroku instance. I've tried re-pushing several times while making small changes, and the css/js never seems to appear.
In case that you have already set:
config.serve_static_assets = true
in your config/environments/production.rb
And still not working, you can actually see the logs from your heroku app using heroku logs or heroku logs -n NUMBER_OF_DESIRED_LINES_HERE in your terminal.

rails 4 static assets not being served even after setting config.serve_static_assets = true

I've created a rails 4, ruby 2 app. In development mode, it's working fine. But if I start the server in production mode, it fails to serve all the images and javascript files.
I've set config.serve_static_assets = true in my production.rb. Still, I get a 404 error. What could be the possible reason?
Any help would be highly appreciated.
When running the server in production mode the system expects that the assets will be precompiled and available in the public folder.
To test this you should run the precompile task. You'll see that a folder called assets is created inside of the public folder, and inside this all your assets will be created.
WARNING: You should delete this folder when you are done testing, and clear the asset cache in the /tmp folder before going back to dev mode. Failing to do this will result in the app serving the precompiled assets in dev mode and you won't see any changes that you make.
