My question is about this Episode: https://gorails.com/episodes/upload-csv-form
The CSV Import works fine (I'm using the exact same code actually).
My 1. Question - How can I define an alias for my rows?
This is the code:
order = Order.where(token: row[:token]).first_or_initialize
order.assign_attributes row.to_hash.slice(:token, :order_id, :customer_id)
How would you implement aliases for token (utm_campaign) order_id (ordernumber) and customer_id (customer)? It's annoying to change the row names each time.
My 2. Question - Accept Semicolons as a Divider
In Germany it is common to use a ";" as a divider inside a .csv. US Standard is a comma. What should be edited so both is possible?
Many Thanks in Advance!
- You'll probably need to modify that hash of attributes from the row. For example, you could transform it this way:
# Accept all fields you could ever want attrs = row.to_hash.slice(:token, :order_id, :customer_id, :utm_campaign, :ordernumber, :customer) # Set aliases attrs.merge( token: attrs.delete(:utm_campaign), order_id: attrs.delete(:ordernumber), customer_id: attrs.delete(:customer) ) order.assign_attributes(attrs)
col_sepoption is what's used to define the column separators. You can add
col_sep: ";"into your CSV parser section and that should do it. Some more info here on options: http://ruby-doc.org/stdlib-2.0.0/libdoc/csv/rdoc/CSV.html
Great. Thank you for your detailed answer! I Just saw, that "order_id" actually is named "reference code" with a space. How do I need to write it :ReferenceCode, or :reference_code ?
You'll actually want to just make sure it matches the column name I think. You can print out the row hash to the console to see exactly what you'll need for that.
