Hi
I have a form for importing a csv file. With every entry in my CSV I
do a delayed background call from a webservice and the result is then
saved to my database. This is working great!
Now I tried a CSV file with over 400 rows. After clicking import in my
form it takes some time and then I get the following error message:
'ActionDispatch::Cookies::CookieOverflow'. But nevertheless 300 of the
400 jobs are already created in my delayed_jobs table.
The code below is copied from other threads, so I don't really know
where I save something in cookies. I guess it is at 'file.tempfile' in
the controller, but I am not sure.
How can I avoid that error? I found something about using
session_store instead of cookie_store, but I don't know how to do
that.
I have the following in my controller:
file = params[:file]
CSV.new(file.tempfile, {:headers => false, :col_sep => ";"}).each
do |row|
@list << row[1]
end
end
and this in my view:
<%=form_tag '/importcsv/csv_import', :multipart => true do%>
<%= file_field_tag "file" %><br/>
<%= submit_tag("Import") %>
<% end %>
Cheers,
Sebastian
