I have a scenario where i will uploading data from excel to database. My
condition for uploading is:
If any of the record has an error all the records should be rolled back.
Plz give me suggestions how to implement if we have a loop.
Let's say you have a ExcelData class which is a subclass of ActiveRecord:
theExcelRecords.each do |currentRecord|
ExcelData.create!( currentRecord )
In this case if any of the currentRecord's are unable to be saved the whole transaction will be rolled back.
I hope this was the information you were looking for.
