Question

So, I’m getting a pretty strange error here… I tried to isolate it but it’s quasi-intermittent. I’m kinda wondering if it has something to do with using capybara with a javascript driver, because this isn’t happening in my non-capybara tests. Here it is:

Failure/Error: @existing_user, household = create_new_user_and_household
ActiveRecord::AssociationTypeMismatch:
 User(#57141560) expected, got User(#42098260)
# ./app/models/household.rb:64:in `block in create_new_household'
# ./app/models/household.rb:62:in `new'
# ./app/models/household.rb:62:in `create_new_household'
# ./spec/support/spec_helpers.rb:55:in `create_new_user_and_household'
# ./spec/integration/accepting_an_invitation_spec.rb:21:in `block (4 levels) in <top (required)>'

Here’s the block in question:

household = Household.new attributes, do |h|
  h.account = user.account || Account.create(user: user)
end

Pretty basic, and works fine when I do it manually in the rails console.

I’m not sure what else to tell you guys… but I’m happy to provide more info.

I’m using rspec for all of my testing.

Answer 1

So the answer, as Frederick Cheung pointed out was to set cache_classes to true in test.rb.

This supposedly conflicts with spork, which is why I was told to turn it off in the first place–since you want spork to re-load your models and whatnot whenever you run another test. The solution is to set cache_classes to true but also put ActiveSupport::Dependencies.clear in your spork prefork block.
