On my new project we had the problem that some specs failed when ran on their own, and some specs produces strange output (like “use object_id”), so I build a helper that runs each test on its own and could pinpoint the problem.
rake spec:one_by_one
it is now included in the single test rails plugin
What good is a dual-core when you do not use it !?
rake spec:parallel[1] –> 86 seconds
rake spec:parallel[2] –> 47 seconds
rake spec:parallel[4] –> 26 seconds
grab the parallel specs rails plugin here!
It requires a bit of setup, but hey: Can you spare 5 minutes now to save 1 minute 100 times a day ?
polymorphic_path(A::B::User) != users_url
which normally would not be a problem, only that polymorphic_path is used in all form_for / link_to etc helpers…
The simpeles solution i found is overwriting User.model_name with:
def self.model_name
ActiveSupport::ModelName.new('User')
end
Update deep_symbolize_keys is in rails 4
Could not find it elsewhere, so here it is: recursive_symbolize_keys, that will symbolize all keys inside a hash and its nested hashes.
Hash extension
class Hash
def recursive_symbolize_keys!
symbolize_keys!
# symbolize each hash in .values
values.each{|h| h.recursive_symbolize_keys! if h.is_a?(Hash) }
# symbolize each hash inside an array in .values
values.select{|v| v.is_a?(Array) }.flatten.each{|h| h.recursive_symbolize_keys! if h.is_a?(Hash) }
self
end
end
Or standalone
def recursive_symbolize_keys! hash
hash.symbolize_keys!
hash.values.select{|v| v.is_a? Hash}.each{|h| recursive_symbolize_keys!(h)}
end
I just found this handy helper:
list.reject(&:nil?) == list.compact
It removes any nil elements from a given array see: docs
