ruby - _destroy isn't working in Coocon gem with Rails 4 -


i have same issue one

but solution didn't me. here strong params:

def request_params     params.require(:request).permit(:name, :address, :phone, :mobile, :type,       :filled_cartridges_attributes => [:cartridge_name,:client_id,,  				:count,:_destroy,:id],

so have :_destroy , :id. guy in previous forgot add :id strong params. adding id solved problem.

here request model:

has_many :filled_cartridges, inverse_of: :request, dependent: :destroy  	accepts_nested_attributes_for :filled_cartridges, :reject_if => :all_blank, allow_destroy: true

and how params after submitting:

request:   ...some params....  filled_cartridges_attributes: !ruby/hash:actioncontroller::parameters      '0': !ruby/hash:actioncontroller::parameters        cartridge_name: hp laserjet3000        _destroy: 'false'        id: '1'      '2': !ruby/hash:actioncontroller::parameters       cartridge_name: new 9       _destroy: '1'       id: '13'

here 2nd 1 should destroyed. doesn't.

you should add :_destroy , :id on permitted parameters specified nested attribute.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
