Hi All,
I need to add the hashes is there any way to add
actually my data is in the given format
data = [ {"first" => 1 ,"second" => 2},
{"first" => 2 ,"second" => 3},
{"first" => 3 ,"second" => 4} ]
I want to acheive it through the loop So, I took 2 hashes as
result = Hash.new
data = Hash.new
for k in 1..4 do
data = {"first"=>k , "second"=>k+1}
result = result,data
end
in the above the result variable
result = [[[[{}, [{"first"=>1, "second"=>2}]],
[{"first"=>2,
"second"=>3}]], [{"first"=>3,
"second"=>4}]], [{"first"=>4,
"second"=>5}]]
But my Output should be as
result = [{"first"=>1, "second"=>2},
{"first"=>2, "second"=>3},
{"first"=>3, "second"=>4}, {"first"=>4,
"second"=>5}]
I tried with the merge,update but those are updating or the changing
the existing the feilds.. the not appending
How can I achieve the output if any help you can save my day...
Thanks

Hema, to be honest, I''m not really sure what exactly you want to
achieve, but maybe you can try this:
result = Array.new
for k in 1..4 do
result << {"first" => k , "second"=> k + 1}
end
The result is:
[{"second"=>2, "first"=>1}, {"second"=>3,
"first"=>2}, {"second"=>4,
"first"=>3}, {"second"=>5, "first"=>4}]
As far as I know there is no easy way to sort the elements of the
inner hashes, but that shouldn''t raise any problem.
Let me know it this works for you.

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?

Think in terms of the domain. What you need is an array of hashes.
Each hash is a representation of your domain object (employee record)
employees.collect {|employee| employee.attributes}
Thats it.
If there are any particular attributes that you don''t want, e.g.
created_at, then use something like
employees.collect {|employee| employee.attributes.except(:created_at)}

Means I can get the hashes as
Result = Hash.new
Result = employees.collect {|employee| employee.attributes}
then the result contails the array of hashes?

But I have another problem,
please check the code

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... Please Help me Thank You
