Rails import CSV with headers that have long names and map to association fields #517

Open billy-whizz opened 5 years ago

billy-whizz commented 5 years ago

I have a CSV of users to upload, with one of the headers named as country of origin of user. This should be mapped to a column in the users table called country_id during importing. country has_many users. I am struggling to import such kind of column headers in the csv which map to an association and which have funny names. Many days of trying but I am yet to crack it. Here is the method I am using to import data:

def load_imported_users spreadsheet = open_spreadsheet header = spreadsheet.row(1) (2..spreadsheet.last_row).map do |i| row = Hash[[header, spreadsheet.row(i)].transpose] user = User.find_by_national_id(row["national_id"]) || User.new user.attributes = row.to_hash user end end Help would be appreciated, thanks!
