Passing an array into Ruby Excel Document Generator - ruby-on-rails

Question

I'm attempting to pass in an array to my Excel file Generator, however I recieve errors such as:
RuntimeError: Not an array ref in call to write_row()
when I attempt to run my script, can anyone tell me how best to pass in data to the following code?
module Accounting
module Datev
module Utils
class ExcelGenerator
require 'writeexcel'
# this class generates excel document and saves it with new path
# Example:
# d = [
# { name: 'Dima', dob: '27/02', city: 'Berlin' },
# { name: 'Conor', dob: '23/04', city: 'Berlin' },
# ]
# Accounting::Datev::Utils::ExcelGenerator.new(data: d, path: '~/text.xlsx').call
# will create excel file text.xlsx in the home directory with the following content
# | name | dob | city |
# | Dima | 27/02 | Berlin |
# | Conor | 23/04 | Berlin |
#
attr_reader :data, :path, :workbook, :worksheet
#array = [
{ name: 'Dima', dob: '27/02', city: 'Berlin' },
{ name: 'Conor', dob: '23/04', city: 'Berlin' }, ]
def initialize(data:, path:)
#data = data
#path = path
end
def call
# TODO: implement me``
create_new_workbook
add_worksheet
write_new_worksheet
save_file
end
def create_new_workbook
#workbook = WriteExcel.new('a_simple.xls')
end
def add_worksheet
#worksheet = workbook.add_worksheet
end
def write_new_worksheet
worksheet.write_row('A1', '#{array}')
end
def save_file
workbook.close
end
end
end
end
end

You didn't need to try convert array to string. But you should use different array format and use write_col method:
def initialize(data:, path:)
#data = data
#path = path
#array = [
['name', 'dob', 'city'],
['Dima', '27/02', 'Berlin'],
['Conor', '23/04','Berlin']
]
end
...
def write_new_worksheet
worksheet.write_col('A1', #array)
end
