Problems with Rails and/or ActiveRecord would best be asked on a Rails  
mailing list (here you have found the general Ruby programming language  
list)

From a Ruby point of view, I’d suggest you try using ‘inspect’ on your  
model before saving it. e.g.

# create your model

foo = Foo.new(…)

# show it

STDERR.puts foo.inspect

foo.save!

This divides your problem in half: if @attributes contains the right  
data then the problem is when ActiveRecord saves it, but if @attributes  
contains the bad data then you can work on the first part of your  
program.

Strange, looks like it’s converting to YAML for some reason.

Sir,

when i add the Code what you gave like STDERR.puts foo.inspect  
it printed like this, i think this is correct data.  
#\<XMLDemo first: [“1”], second: [“2”], third: [“3”], child1: [“First”],  
child2: [“Second”], child3: [“Third”], id: nil\>

But still i am facing the same problem. plz help to solve this prb

Thanks in Advance

No, that’s wrong, and it explains why your data is getting serialized as  
YAML.

Each of your attributes is an array:

[“1”]

when it should be just a string

“1”

XmlSimple is giving you an array because you might get multiple elements  
with the same name:

 foo bar baz ...

So your code which copies from your XML structure into your ActiveRecord  
model needs changing, e.g. by using .first or [0] to pick the first  
array element.

I have a vague recollection that there’s an option you can pass to  
XmlSimple for it _not_ to put elements inside arrays; look through the  
docs.

You are correct. I just had similar problem as OT.  
The option is ‘ForceArray’ =\> false
