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.

1. Your class can be no longer than 100 lines of code.
2. Your methods can be no longer than five lines of code.
3. You can pass no more than four parameters and you can’t just make it one big hash.
4. When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.

Migrating from Postgres 9.0/Postgis 1.5 to Postgres 9.2/Postgis 2.0 on Heroku

This may not be relevant to many, but it's a process that I just had to go through and it was a bit tricky to figure a smooth way to make it work.

The gist of it is that you must do the following:

• Export your production database from heroku to your local machine
• Create a new, blank database with Postgres 9.2 and PostGIS 2.0
• Import your heroku database into the new local database running 9.2/2.0
• Dump the new database and upload it to S3
