Question

I’m trying to piece together a part of a create action in a controller that scans the the text entered and intelligently understands what type of domain name it is.

I have a text box called “domain_names”. A user puts domains into the box separated by commas, e.g. “yahoo.com, google.com”

In the controller it hits it like this:

@extracted_domains = (params[:domain_names]).split(",")
@extracted_domains.each do |domain|
    domain.strip
    domain_scan = domain.scan(/(\w+)[.]/).flatten
    com_scan = domain.scan(/[.](\w+)/).flatten
    new_domain_type = DomainType.find_or_create_by_domain_type(:domain_type => com_scan)
    new_domain = Domain.create(:domain => domain_scan, :domain_type_id => new_domain_type.id)
end 

In the console it works great. But when I put it into practise I get really odd things stored in the database. For example if :domain was meant to have the value “google”, it will instead have the value “—\n- google\n” , when its stored in the database.

No idea why

Thanks in advance.

UPDATE**

Problem: It was putting an array into a string.

Solution: Make it a string.

domain_scan = domain.scan(/(\w+)[.]/).flatten.first
com_scan = domain.scan(/[.](\w+)/).flatten.first

As for your issue, can we see the exact params that are sent?

I would take a look at https://github.com/pauldix/domainatrix for domain extraction.
