[BangPypers] calling instance of the other class.
Dear Python experts, Please can you help in a following scenario.. I have some classes each for a Protocol Data Unit which you could consider as a structures of elements example class ex1: class usr_mac(MAC_PDU): ''' Group Voice Channel User ''' def __init__(self): self.protectFlag = BV.Bit1.new() self.reserved = BV.Bit1.new() self.flco = BV.Bit6.new() self.grpAddr = BV.Bit24.new() self.srcAddr = BV.Bit24.new() self.order = ['protectFlag', 'reserved', 'flco', 'grpAddr', 'srcAddr'] Now i have a another message which i need to create similar but now it contains the above class instance as one of the members. Please can you tell me how to pass instance of above class as a member of the new message created in similar lines with one of the elements is the complete data above (instance of above class). I am encapsulating above message in a transport layer message. 2. Now similarly, i would like given a choice to choose the instance of other class as the i would like to pass in other instance of class similarly. Your kind help will be greatly appreciated. Please let me know if there are clarifications i can give, I am posting this in a hurry. I am sure there could be questions.

I am totally confused by the description. :( If you still not very comfortable with Class terminologies in Python, I would suggest you read any basic book (2-3 hours on the topic would be enough) and perhaps you may find, what you are trying to do is easy? -- Senthil I do not find in orthodox Christianity one redeeming feature. -- Thomas Jefferson ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

[...] There is definitely a "connection" variable in django/db/__init.py__ which is where django/db/models/__init.py__ is importing from. I suspect that this is some other issue, maybe a problem with connecting to the database. What database are you using? Can you connect to the database, using some other tool, but with the same username/password as in Django's settings.py?

Re: [BangPypers] calling instance of the other class.
Sorry Senthil and all, I am sure, it's pretty easy but don't i am not able to catch it. In C, i just pass the & of the another structure in the structure element, some thing close. Here is what i do .. a class is defined as mentioned, now this class is element of another class class Send_Msg_req(msg): def __init__(self): self.usr_mac =< Earlier class defined > self.msgtype = self.msgsize = self.order = ['usr_mac', 'msgtype ', 'msgsize '] Now i like your expertize in giving me tips so that i have to declare and keep sending above this message over serial port, but each time with different class. I hope i made it bit more clear. Sorry for the confusion.
