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

Hi - see below... hema gonaboina wrote: ...> 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 fieldsYou used ''Fields'' above instead of ''fields'' here.> res << { field => employee.send(field)}res[field] = employee.send(field) ''res'' is a hash. You build it by setting key/value pairs not pushing onto a sequential array. That should probably do it. Some other things that might be of interest: employee.attributes will give you a hash of all the fields and their values for an employee object but you might only be wanting a subset. (You could ''delete'' them.) Employee.column_names will give you an array of all the column names.> 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-- Daniel Bush --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
