Thanks,
Point taken about less interaction with the database. The 'companies'
mock is an exact representation of the companies list returned by the
basecamp api which is why there's 37 records in there. I need to learn
to think more clearly about separation from the database I guess.
The point is actually that none of these examples are touching the
database at the moment because rspec doesn't know about the
companies.each do loop in the model. I'm wanting to cycle through the
list of companies in the fetched array and save these as rows in the
database.
I have done a basic implementation of this in the model, but I can't
get this through to rspec.
