Factories block migrations about factory_bot_rails

[mulderp]

Sorry. Mistake on my side.
In my Factory I include something like:

f.roles [ Role.find_by_name("foobar") ]

meaning, the call is triggered while there is no Role yet.

for those having similar problems, have a look at the discussion here:

Can you paste the contents of spec/factories/bar.rb?

[mulderp]

Factory.define :bar do |f|
f.name { "#{Faker::Company::name}-Shop-#{rand(1000).to_s}" }
f.roles do [ Role.find_by_name("Shop") ] end
end

Without the do ... end the factory would block the migration, because Role.find_by_name is not yet functional during db migration.
So, that was the mistake that I made earlier.

I had this same issue. How exactly does the block fix the problem?

Factory definitions are evaluated at run time. You need to make sure that any ActiveRecord models aren't directly referred to until the factory runs (rather than when the factory is defined). Otherwise, ActiveRecord will try to check the table for columns before the migrations have run.
