Lua inserting a record to a table is failing -

i have main script follows . script called script.lua (for sake of example)

require "modules\\myparentclass" require "modules\\condition" require "modules\\helpers" require "constants"  parentclass = myparentclass:new() print ("myparentclass type : " .. parentclass:getcode())  -- add conditions  -- condition 1 condition1 = condition:new(nil,"are happy?" , "yes") parentclass:addcondition(condition1)  -- -- condition 2 condition2 = condition:new(nil,"are sad?" , "no") parentclass:addcondition(condition2)   local l = parentclass:getconditions()  print(l[2]:getquestion()) 

i have class called myparentclass code follows

require "constants" require "modules\\condition" require "modules\\helpers"  -- meta class myparentclass = {code = ""}   function myparentclass:new (o)    o = o or {}    setmetatable(o, self)    self.__index = self    self.condition = condition    self.conditions = {}    return o end  function myparentclass:getcode ()    return "parent class" end  function myparentclass:addcondition(condition)     print(condition)     table.insert(self.conditions,condition)     print('record inserted')     -- self.conditions = {next= self.conditions, value = condition} end  function myparentclass:getconditions()     return self.conditions end 

and have third class , conditions follows

require "constants"   -- meta class condition = {question="", answer=""}  function condition:new (o, question,answer)    o = o or {}    setmetatable(o, self)    self.__index = self    self.question = question or nil     self.answer = answer or nil    return o end   function condition:getcode ()    return condition_type end  function condition:getquestion()     return self.question end  function condition:getanswer()      return self.answer end 

the idea in main script (script.lua) ,

1. i can create new parent class.
2. each parent class can have multiple conditions (aka questions).

for me, first part working. failing second part. whenever run script , 2 instances of second question. please see below snapshot more details.

.

ideally, have both conditions displayed ("are happy?" , "are sad?") not case.

can please me out one?

take @ constructor

function condition:new (o, question,answer)    o = o or {}    setmetatable(o, self)    self.__index = self    self.question = question or nil     self.answer = answer or nil    return o end 

everytime call change value of condition.question , condition.answer self refers condition, not new object o!

so create 2 new tables condition1 , condition2 both don't have own .answer , .question. therefor access metatable condition after created condition2 contains: "are sad?" , "no")

if want initialize members in constructor have use o.answer , o.question.

make sure understand how metatable stuff works.
