What is the difference between Rails data types?

Question

I know that Rails data types can be found here:

Rails 4: List of Available Data Types

or here:

http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/TableDefinition.html#method-i-column

but what I can’t find is a clear definition of each, as well as the differences between, say, a float or decimal, or string compared to text.

Where can I find detailed definitions of data types?

Answer 1

Here's a nice set of definitions (from fooobar.com/questions/21411 / ... )

• binary - for storing data such as images, audio or movies.
• boolean - .
• date -
• datetime - .
• decimal - .
• float - . ( ?)
• integer - .
• primary_key - , .
• string - , . ( ?)
• - , .
• -
