Create pdf using ruby on rails

I have a problem,

please check the code

Fields = Array.new
Fields [0] = “sno”
Fields [1] = “username”
Fields [2] = “designation”
Fields [3] = “salary”
Fields [4] = “dob”
Fields [5] = “email”
Fields [6] = “doj”

These are the fields of the object ‘Employee’

The Employees array contains of the set of employee objects…

I need to have the array of hashes as
[{employee_record1},{employee_record2}… n records]

For this i tried as the…

result = []

for employee in Employees
res = {}
for field in fields
res << { field => employee.send(field)}
end
result << res
end
But it is not working…

Finally i have to replace the ‘result’ with the PDF::SimpleTable.data
through the statement

=> table.data.replace result

which accepts only the hashes… whose columns are the keys and the
column
data as values

Please Help me Thank You
