Bidimensional Array

Rails
1

Hi,

As I can initialize and add to a bidimensional Array?
I am mirnado in api and I do not see anything it clear.

I am proving thus, but it gives error me:

$itemlist = [][]
$itemlist << Item.new(‘name1’,‘value1’)

Thank you very much.

You don’t need to declare it as bidirectional. Something like this may
be what your looking for, if not supplying a little more information
would help:

$itemlist = []
$itemlist[0] << Item.new(‘name1’,‘value1’)

This is assuming that Item.new returns an array, that would leave you
with a multi-dimensional array.

Thanks William.
With $itemlist = [] does not work either. :frowning:

My total code is this:

require “uri”
class EstablishmentTypeTemplatesController < ApplicationController
def enviaListaItem
sRedirect = “/establishment_contents/list?”
@params[‘item’].each_pair {|key, value|
sRedirect << key << “=” << value << “&”
}
enc_url = URI.encode(sRedirect)
redirect_to enc_url
end
def select
if !(params[:addLista]) then
$itemlist = []
$itemlist << Item.new(‘Sobre el Bar’,‘1’)
$itemlist << Item.new(‘Dónde Estamos’,‘1’)
$itemlist << Item.new(‘Contactar’,‘1’)
end
end
def addItem
if (params[:nombreItem]) then
$itemlist << Item.new(params[:nombreItem],‘1’)
render :action => ‘select’, :templateID => params[:templateID]
end
end
end

And this it is the error that it gives:

ArgumentError in Establishment type templatesController#select
wrong number of arguments (2 for 1)
RAILS_ROOT: ./script/…/config/…

Response

Thanks again.

Looks like the constructor for your Item class only takes one
argument. What is Item ? (and do you really want a global variable?
that will fall over as soon as you have more than one mongrel or more
than one user).

def select
if !(params[:addLista]) then
$itemlist = []
$itemlist << Item.new(‘Sobre el Bar’,‘1’)
$itemlist << Item.new(‘Dónde Estamos’,‘1’)
$itemlist << Item.new(‘Contactar’,‘1’)
end
end

Item.new(‘Sobre el Bar’,‘1’) are trouble (ArgumentError)
You should do:
Item.new(:name => ‘Sobre el Bar’, :number=>‘1’)
mean you need describe methods/field names by your model Item.

Hi, it appears that there’s an issue with the select method. Could you
post
it here?
Thanks,

Thanks to all.

My problem was as you said, that it thought that to add to a list it was
necessary to make a New of a variable.

Now I have it thus and it works to me

def select
if !(params[:addLista]) then
$itemlist = [[‘Sobre el Bar’,‘1’], [‘Dónde Estamos’,‘1’],
[‘Contactar’,‘1’]]
end
end
[…]
$itemlist << [params[:nombreItem],‘1’]

Thank you very much.
