When I migrate codes from 1.1.2 to 1.2.3, the serialize in ActiveRecord failed to deserialize object correctly.
Relevant model classes of ListTracker, QueryList and Query
class ListTracker < ActiveRecord::Base
serialize :query_list
serialize :query
belongs_to :user
end
class QueryList
attr_accessor :class_name
def initialize(class_name = "")
@items = []
@restrict_items = []
@class_name = class_name.strip
@order_field = "id"
@order_direction = ""
@sort_items = []
@table_included = Set.new
end
def class_name
@class_name ||= ""
end
......
end
class Query
attr_accessor :key, :value, :exact, :op, :join, :negation, :table, :before_blanket_count, :after_blanket_count
def initialize(key, value, table, op = "eq", join = "AND", negation = false, before_blanket_count = 0, after_blanket_count = 0)
@key = "#{key}".strip
value = "1" if value == true
value = "0" if value == false
@value = "#{value.to_s}".strip
case op
when true
@op = "eq"
when false
@op = "st"
when "eq", "ne", "lt", "gt", "le", "ge", "bl", "in", "st", "en"
@op = op
else
@op = "eq"
end
@join = "#{join}".strip
@negation = negation
@table = table.strip || ""
@before_blanket_count = before_blanket_count.to_i
@after_blanket_count = after_blanket_count.to_i
end
......
end
In 1.1.2, the behaviour is
>> t = ListTracker.find(:first)
=> #<ListTracker:0x40832058 @attributes={"updated_at"=>"2007-05-14 12:07:06", "module"=>"contacts", "query_list"=>"--- !ruby/object:QueryList \nclass_name: Contact\nitems: \n - !ruby/object:Query \n after_blanket_count: 0\n before_blanket_count: 0\n join: AND\n key: id\n negation: false\n op: eq\n table: contacts\n value: 8543be1e-01d0-11dc-b78c-001372588291\norder_direction: ''\norder_field: id\nrestrict_items: []\nsort_items: []\ntable_included: !ruby/object:Set \n hash: {}", "id"=>"64", "user_id"=>"f7163ddc-fc4a-11da-81a0-000c6e8c7636", "order_by"=>""}>
>> t.query_list
=> #<QueryList:0x40826e38 @restrict_items=[], @class_name="Contact", @sort_items=[], @order_direction="", @order_field="id", @table_included=#<Set: {}>, @items=[#<Query:0x4082dd14 @negation=false, @op="eq", @join="AND", @table="contacts", @after_blanket_count=0, @before_blanket_count=0, @value="8543be1e-01d0-11dc-b78c-001372588291", @key="id">]>
It will load the QueryList object.
In 1.2.3,
>> t = ListTracker.find(:first)
=> #<ListTracker:0xb6df9ca4 @attributes={"module"=>"contacts", "updated_at"=>"2007-04-04 16:13:17", "query_list"=>"--- !ruby/object:QueryList \nclass_name: Contact\nitems: \n - !ruby/object:Query \n after_blanket_count: 0\n before_blanket_count: 0\n join: OR\n key: id\n negation: false\n op: st\n table: contacts\n value: 62d703da-707c-11db-80be-000c6e8c7636\n - !ruby/object:Query \n after_blanket_count: 0\n before_blanket_count: 0\n join: OR\n key: id\n negation: false\n op: st\n table: contacts\n value: 1faad762-707c-11db-80be-000c6e8c7636\norder_direction: ''\norder_field: id\nrestrict_items: []\nsort_items: \n - !ruby/object:QuerySort \n descending: false\n field: created_at\n field_type: contacts\n summary: false\ntable_included: !ruby/object:Set \n hash: {}", "id"=>"64", "order_by"=>"", "user_id"=>"f7163ddc-fc4a-11da-81a0-000c6e8c7636"}>
>> t.query_list

Deserializing it gives a strange class of YAML::Object.
Hopefully there would be a fix so that it can deserialize like 1.1.2.
