django - Make a copy of a model instance -


i have following code:

class person(models.model):     name = models.charfield(max_length=32, verbose_name=_(u"name"))     surname = models.charfield(max_length=32, verbose_name=_(u"surname"))     address = models.charfield(max_length=32, verbose_name=_(u"address"))  class contract(models.model):     person        = models.foreignkey(person) #person hired     project       = models.foreignkey(project, blank = true, null = true)     starting_date = models.datefield(blank = true, null = true)     ending_date   = models.datefield(blank = true, null = true)

each person shown own contract through inline.

i need able modify contract without removing contract i'm modifying, record of contracts person has had. mean, i'll have make copy of contract want modify , make changes in copy @ end i'll have both contracts (the previous 1 , modified version of one).

i guess need link or button next every row of inline in order go contract admin page , modify copy of particular contract.

so far, i've seen some ways make copy don't know how use them need.

does know how go it?

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
