I managed to create my first ROR application, called myapp, locally and I also have created another ROR application on my webfaction server with the same name myapp. My question is every time I run commands "rails generate model" or "rails generate controller", how can I synchronise my local environment with my webfaction server. There seem to be lots of files generated when you run rails commands. Does it mean I have to upload the whole application directory every time I generate something? Kindly suggest with your experience, I'm very new to Rails.
If I were you I would go for Heroku first. It's free and easy and along the way you will learn some about hosting Rails apps.
Getting started with Heroku is a good place to go first https://devcenter.heroku.com/articles/quickstart
Heroku is indeed the easy way out, if you are looking into more "metal" deployment - use Capistrano

I ssh copied a rails app from a staging server because the development repository has been lost. My goal is to create a new development code base using the deployed code as a source. So far I have removed a hidden .bundle folder and replaces several aliases with folders and files. I then ran bundle install. For the database I did a sql dump from staging and used it to build a development database. I think I'm ready to run rails server. But when I try to run rails server in the base directory. It gives me the rails command line help as if I was running rails s in a directory with no app.
I'm not even sure if it is possible to reverse a deploy this way. I've looked at the rails guide on the app initialization process and all the files seem to be in place.
Remember that for Rails to start up, you need bin/rails, bin/bundle, config/boot, etc.
If you restore those files, it should work again.
I'm pretty new to Rails.
I created a new Rails app: rails new app_name, and ran rails server etc.
But, once I shut down and reopened my machine, I can run neither rails server nor rails console. It says to use the rails new app_name command again, but I just want to restart where I left off the day before.
Any advice is very much appreciated.
I'm guessing your current working directory of your command line is not in your project directory which you created yesterday.
cd some_path/to_my/rails_project
rails server
You must be in the directory that represents your project to do things like launch the server. Otherwise, how does it know what project to launch a server for?
Just make sure you are in the directory of the rails app you created. Sounds like you aren't.
Is there an issue with developing my site on my macbook and then moving to a server when done? Will there be issues I need to plan ahead for? DB or ruby related maybe? Dependencies or something a server could have different from my dev environment that could cause a nightmare later? I'd rather develop it offline since it'd be faster and wouldn't require an internet connection but in the past I've always done everything with live sites so this would be a first, and I am new to ruby on rails.
Developing locally and then deploying to your server(s) via something like capistrano is standard practise.
It's a good idea to keep your development environment as close as possible to your production environment (ruby versions, database versions etc). Bundler makes keeping your gems in sync easy
I used Heroku for some projects. The deployment was as easy as it could be. I just did a git push and it worked without problems... I really like bundler and rake :-)
Your Question embodies THE way to develop in Rails. Your development environment is an offline representation of what you're production site will be.
A quick workflow analysis for you could be:
rails new ~/my_app -d postgresql; cd ~/my_app; rm public/index.html
Next, create the database:
bundle exec rake db:create:all
Now you'll have the db and app all set up, let's set up your main pages:
bundle exec rails generate controller Site index about_us contact_us
Now you'll have something to see on the site, so run:
bundle exec rails server
This server acts as your offline connection and will handle the rendering of any text, images, html etc you want to serve in your rails app. Now you can join in the debates of TDD, to TATFT or JITT, rspec vs test::unit. Welcome.
Developing locally is definitely the way to go. However, I would look into getting it on production as soon as possible and pushing often. This way you can see changes happen as you make them and are aware of any possible breaking changes.
I use heroku a lot and when I start a new project I push it to heroku almost immediately. While developing, I can publish new changes simply by git push heroku master. Everyone has to find their own workflow, but this has always worked well for me.
If you are interested in Heroku here is a good link to get you started:

I'm trying to deploy my rails application with heroku (as shown here). I've created a very simple rails application (using ruby 1.9.2 and rails 3.0.3; i'm sure heroku supports these - see heroku docs), created and pushed github repo, created heroku repo and pushed it (all commiting is done). And when i'm trying to access my application controller, it throws 404 rails page like it's saying 'there is no such controller'. I've done heroku rake db:migrate but first time i ran it i got 'host not found' error. Running this again fixed that. Well, i'm not sure if i should run heroku addons add:postgresql - i though postgres is on by default, but heroku says i should pay in order to get DB (running command i've mentioned asks me to confirm billing it).
May be it sounds stupid, but how can i deploy my rails application (it's a very simple one) without paying any fees and such troubles as 404 pages like i mentioned in the beginning of my post? (and this is my question). Maybe i should choose other hosting (if it exists in our world) or am i doing something wrong with heroku?
You forgot to push your quotes_controller.rb to git and heroku probably.
git add controllers/quotes_controller.rb
it seems you forgot models also, and probably lot of files.
I have a deployed Rails application that I'd like to use with Hoptoad (an online exception notification service). It comes packaged in a gem that I installed on my deployment server, but I need to run the script/generate hoptoad every time I deploy to configure it because the Hoptoad config files/changes exist only on my production application (and not on my development, so when I deploy, they all get erased).
Is there an easy way to run that script/generate on the production server every time I deploy? I feel like you could do this with Capistrano tasks, but I don't know how to do that.
What do people usually do for this? Sorry if this post is a little hard to understand, I'm not quite sure how to explain the issue.
Thanks!
You can add the Hoptoad configuration file to your source code repository so that it gets deployed as part of the Rails application.
Alternatively, if you don't want that information within your repository, then upload the config file to your production server (outside of Capistrano's normal releases directory structure) and have Capistrano create a symbolic link to it as part of the deployment process. I provided an answer to a similar question here which should give you the idea.
