Hi Guys,
I am using import CSV to import from a csv file to my database in my
rails app. I want to be able to be able to add a list of email
addresses from this file but also include the mailinglist_id which is
a param[:id] on my page in the database entry. So in effect adding a
csv of emails to any mailing list.
I am just a little unclear as to how I add the extra field when adding
the data to the database… any help would be great!!
Database table “mailings” is as follows…
mailinglist_id, id, name, email_address
import_csv controller
def csv_import
file = params[:csv_import][:file]
logcount=0
Mailing.transaction do
FasterCSV.parse(file, :headers => true) do |row|
Mailing.create!(row.to_hash)
logcount += 1
end
end
flash[:notice] = “Successfully imported #{logcount} email(s)
from mailing list.”
redirect_to :action => :index
rescue => exception
# If an exception is thrown, the transaction rolls back and we
end up in this rescue block
error = ERB::Util.h(exception.to_s) # get the error and HTML
escape it
flash[:error] = “Error adding list. (#{error}). Please try
again.”
redirect_to :action => :index
end
index.html.erb
<% form_for :csv_import, :url=>{ :controller=>“import_csv”, :action =>
‘csv_import’},
:html => { :multipart => true } do |f| %>
<%= f.label :file, 'Import mail list file' %>
<%= f.file_field :file -%>
<%= submit_tag "Submit" %>
<% end %>
