Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# delete index (will print an error if 'my_index' doesn't exist, you can safely ignore it)
curl -XDELETE 'http://localhost:9200/my_index'

# create index with its settings
curl -XPOST 'http://localhost:9200/my_index' -d '{
    "index.analysis.analyzer.default.type":"custom",
    "index.analysis.analyzer.default.tokenizer":"standard",
    "index.analysis.analyzer.default.filter.0":"lowercase",
    "index.analysis.analyzer.default.filter.1":"asciifolding"
