Title: Introduction Letterpress - the model factory for the lazy people.

Why yet another model factory gem?

In this blog post I will try to explain what my goals are for Letterpress.

No DSL

As a consultant I have worked on many different Rails projects and most of them use model factories to populate their models with default values. I love to use model factories when writing tests. But I have one concern: I have to learn yet another DSL to be able to populate my models with default values. That feels wrong to me.

StringTemplater with no tokens
- returns blank string if the given string is blank
- returns a non-blank string unchanged

StringTemplater with one token
- replaces token with empty string if no value in context
- replaces token with value from context
- leaves the rest of the string unchanged

StringTemplater with two tokens
