tl;dr

If you must nest functions in a way that requires access to multiple this', alias outer this to something meaningful - describe the value it's holding. Treat this as the invisible first argument.

In general though, avoiding the situation (nested functions and frivolous use of this) will frequently produce clearer results.

Naming this in nested functions

I was accidentally included in a discussion on how to best name this in nested functions in JavaScript. +1's were given to this suggestion of using _this.

Giving style advice on naming nested this without a meaningful context isn't too helpful in my opinion. Examples below have been altered to have at least some context, although a completely contrived and stupid one.

Install with Homebrew

brew install mongodb

Set up launchctl to auto start mongod

$ ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

/usr/local/opt/mongodb/ is a symlink to /usr/local/Cellar/mongodb/x.y.z (e.g., 2.4.9)

2. bundle
3. Run RAILS_ENV=production rake db:create db:migrate db:seed
4. Run rake secret and copy the output
5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
