(Rails) Is there a way to check the field's datatype?

Question

How do you check what the datatype is for something that was retrieved from the database?

For example, if I have some instantiation of a model @model with a database

Answer 1

Try this:

@model.column_for_attribute('title').type

Should return :string, :text, :integer, etc.

The ActiveRecord Column class also includes a number of other attributes: default, limit, name, null, precision, primary, scale, sql_type, type.
