mysql - How to make sure that SQL statement is executed and only then start next code step -


i have strange behaviour when executing ruby code. make new model @user = user.first_or_initialize , @user.save what's strange when after try devise helper method sign_in @user fails because time sql query hasn't been executed. have seen in console. made puts @user.inspect right after sign_in @user. , in terminal i've got unpleasant surprise, puts @user.inspect showed me user model without id means sign_in @user passed user without id. , sql query insert users made after put shown in terminal.

so question, how can lock ruby code execution, until sql statement has executed? when pass @user sign_in passes user model id ???

edit:

@user = user.where(:uid => @shop[:uid]).first_or_initialize  if @user.persisted?   puts 'persisted.'   false else   # new customer   ....     @user.save    sign_in @user end

i sure record not getting saved , when inspecting record showing initialized copy of object, can use save! see if there exceptions or user.first_or_create!

@user = user.first_or_initialize @user.save!

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 ...
