c# - MVC5 model binding -- child objects all null -


when parent class/model posted server , use bindattribute "bind", child objects null.

if don't include binding, works
public actionresult saveedit(int id, person person)

for instance person.address property not null, , it's properties set based upon form submission.

just fyi, address created in view using editorfor, included in request form.

but if use bind, doesn't work..

public actionresult saveedit(int id, [bind(include = "personid, addressid, address.addressid, address.line1, address.city, address.state, address.zip")] person person)

person.personid , person.addressid set correctly, person.address null.

if use bind , multiple parameters, so...

    public actionresult saveedit(int id, [bind(include = "personid")] person person,         [bind(prefix = "address", include = "addressid, line1, city, state, zip")] address address)

it halfway works, both object created, neither has related properties there.

is normal behavior, or have done wrong?

you have not shown model, assuming contains properties personid, addressid , address address complex object needs be

public actionresult saveedit(int id, [bind(include = "personid, addressid, address")] person person)

however, better approach use view model containing properties editing , avoid use of [bind(include = "properties, list")]

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 ...
