So I have this:
({:company_profile_id ["2"], :topic :company, :url ["mikeshawauto.com"]})
And then I get this field name and value:
(:company_profile_id)
(["2"])
The next 3 lines of code are:
old-field-value (get old-documents field-name [])
new-field-value (into old-field-value field-value)
document (assoc document field-name new-field-value)
And when the function is next called, I end up with :
({:company_profile_id ["2"], :topic :company, :url ["mikeshawauto.com"]})
I need:
({:company_profile_id ["2", "2"], :topic :company, :url
["mikeshawauto.com"]})
So perhaps I've misunderstood what (into) is for? How do I add another the
values of these 2 vectors together?
