Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.

Initial setup

To start, create some plans.

Backstory: I decided to crowdsource static site generator recommendations, so the following are actual real world suggested-to-me results. I then took those and sorted them by language/server and, just for a decent relative metric, their Github Watcher count. If you want a heap of other projects (including other languages like Haskell and Python) Nanoc has the mother of all site generator lists. If you recommend another one, by all means add a comment.

Recently, I had a staging database on Heroku that was running on the Ronin database (which was originally the lowest-sized DB you could get at Heroku). Since they added two new options, Crane and Kappa, we wanted to take advantage of the cost savings. Here's how you can migrate your Ronin DB to Crane (or any other plan).

The old database was named BROWN while the new one is CRIMSON. You can determine this by running:

heroku pg:info --app myapp-staging

1. Add Crane database

    heroku addons:add heroku-postgresql:crane --app myapp-staging
   

heroku pg:wait --app myapp-staging

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

• install packages for vim, git
• create user accounts, as specified in included JSON config files
• install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM
