• JavaScript: Is there any "python's Generator" equivalent in JavaScript?

  - by JackSMTV

  Is there any "python's Generator" equivalent in JavaScript? PS: Python's Generator is very memory efficient when we need to do one time iterate through a big array, hash... "Generators are iterables, but you can only read them once. It's because they do not store all the values in memory, they generate the values on the fly" (Python's Generator explained in this thread: The Python yield keyword explained )

• Django: Converting an entire Model into a single dictionary

  - by LarrikJ

  Is there a good way in Django to convert an entire model to a dictionary? I mean, like this: class DictModel(models.Model): key = models.CharField(20) value = models.CharField(200) DictModel.objects.all().to_dict() ... with the result being a dictionary with the key/value pairs made up of records in the Model? Has anyone else seen this as being useful for them? Thanks. Update I just wanted to add is that my ultimate goal is to be able to do a simple variable lookup inside a Template. Something like: {{ DictModel.exampleKey }} With a result of DictModel.objects.get(key__exact=exampleKey).value Overall, though, you guys have really surprised me with how helpful allof your responses are, and how different the ways to approach it can be. Thanks a lot.

• Permission to view, but not to change! - Django

  - by RadiantHex

  Hi folks, is it possible to give users the permission to view, but not to change or delete. currently in the only permissions I see are "add", "change" and "delete"... but there is no "read/view" in there. I really need this as some users will only be able to consult the admin panel, in order to see what has been added in. Help would be amazing!

• Why doesn't this work?

  - by Kyle W

  take = raw_input('Please enter the string of numbers that compose code\n\n\t') y = str(take) l = [] for i in xrange(0, len(y), 3):         l.append(str(y[i:i+3])) b = len(l) a = 0 while(a!=b):         c = l[a].replace('444', ' ')         c = l[a].replace('111', 'a')         c = l[a].replace('112', 'b')         c = l[a].replace('113', 'c')         c = l[a].replace('114', 'd')         c = l[a].replace('115', 'e')         etc...         a = a + 1 filename = 'decmes.txt' file = open(filename, 'w') file.write(c) file.close() I can enter anything, just 111 for example and it gives me back the same thing I put in. Maybe it's something dumb, but I can't figure it out.

• speeding up parsing of files

  - by user248237

  the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.) this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.) how can I speed it up? def csv2dictlist_raw(filename, delimiter='\t'): f = open(filename) header_line = f.readline().strip() header_fields = header_line.split(delimiter) dictlist = [] # convert data to list of dictionaries for line in f: values = map(tryEval, line.strip().split(delimiter)) dictline = dict(zip(header_fields, values)) dictlist.append(dictline) return (dictlist, header_fields) thanks.

• Implementing a 30 day time trial

  - by svintus

  Question for indie Mac developers out there: How do I implement a 30-day time trial in a non-evil fashion? Putting a counter in the prefs is not an option, since wiping prefs once a month is not a problem for an average user. Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?
