Hi ,
I need to acheive the result to be as
result = [{"first"=>1, "second"=>2}, {"first"=>2, "second"=>3},
{"first"=>3, "second"=>4}, {"first"=>4, "second"=>5}]
since this hash is the PDF::SimpleTable.data format
the table data accepts the hash values with the keys as columns and
the values as the table rows
In this case i have to create the report from the database records I
have the Array of employee objects with the fields
I need to put them in table format so that first I have to make the
column names as the table column headings and then need to form a row
of values
For example my 'employees' contains the employee object
then, each object has to become one value in the hash
data = Hash.new
result = Hash.new
for employees.each do |record|
data = {"Sno" =>
record.sno, Here
i have one record
"UserName" => record.username,
"designation" => record.designation,
"salary" => record.salary }
result = data,result
end
I want result should be in the following format
result = [{"Sno" => 1,"UserName" => "ppp","designation" =>
"se","salary" => 10000},{"Sno" => 2,"UserName" => "xxx","designation"
=> "se","salary" => 10000},{"Sno" => 3,"UserName" =>
"yyy","designation" => "se","salary" => 10000},{"Sno" => 4,"UserName"
=> "zzz","designation" => "se","salary" => 10000}]
then I could replace the table data
table.data.replace result
table.render_on(pdf)
But I am not getting the required format? How to achieve that?
