The company I'm currently contracting at has released their first piece of
Open Source Software, a Ruby gem for interacting with REST servers. There
are other gems out there but we wanted something that felt more like using
ActiveRecord (like ActiveResource) but more customisable.
When I create a table with the following SQL:
# create table foos (id SERIAL, content VARCHAR(255));
And define a class as follows:
class Foo ActiveRecord::Base
serialize :content, JSON
end
Creating a new instance of the class gives an error:
f = Foo.new
NoMethodError: undefined method
the second argument to serialise is used to say that you always want
the serialised object to be of a certain class (e.g. Hash, an
application specific class etc.). I'm not sure what you meant by
passing JSON as that argument but I suspect that it isn't doing what
you think it is.
I was
I was basing it on this article (as well as a stack overflow answer) that you
can provide a custom serializer in Rails 3.1:

JSON provides a dump and load method on
