  • Choosing between JSON and XML

    - by Midhat
    Previously I used XML soap for data exchange in my web services, But switched to json for another project. Now I cant seem to find a reason to go back to XML, primarily because of the response size difference for large objects. In what case would you need to use XML over json for web service response

  • How can I transfer an NHibernate PersistentGenericSet over WCF

    - by Ian Oakes
    I'm trying to send objects retrieved by NHibernate over WCF, but whenever a have a property of ICollection I get an exception. When NHibernate gets the data from the database this property is intitialized with an instance of PersistentGenericSet. Is there a way I can send a PersistentGenericSet over WCF? -or- Is there some way making NHibernate initialize these properties with another type?

  • Splitting only long words in string

    - by owca
    I have some random string, let's say : s = "This string has some verylongwordsneededtosplit" I'm trying to write a function trunc_string(string, len) that takes string as argument to operate on and 'len' as the number of chars after long words will be splitted. The result should be something like that str = trunc_string(s, 10) str = "This string has some verylongwo rdsneededt osplit" For now I have something like this : def truncate_long_words(s, num): """Splits long words in string""" words = s.split() for word in words: if len(word) > num: split_words = list(words) After this part I have this long word as a list of chars. Now I need to : join 'num' chars together in some word_part temporary list join all word_parts into one word join this word with the rest of words, that weren't long enough to be splitted. Should I make it in somehow similar way ? : counter = 0 for char in split_words: word_part.append(char) counter = counter+1 if counter == num And here I should somehow join all the word_part together creating word and further on

  • Drupal PHP error zval can't be arrays

  • Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

    - by Omer Raviv
    Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

  • List of Django model instance foreign keys losing consistency during state changes.

    - by Joshua
    I have model, Match, with two foreign keys: class Match(model.Model): winner = models.ForeignKey(Player) loser = models.ForeignKey(Player) When I loop over Match I find that each model instance uses a unique object for the foreign key. This ends up biting me because it introduces inconsistency, here is an example: >>> def print_elo(match_list): ... for match in match_list: ... print match.winner.id, match.winner.elo ... print match.loser.id, match.loser.elo ... >>> print_elo(teacher_match_list) 4 1192.0000000000 2 1192.0000000000 5 1208.0000000000 2 1192.0000000000 5 1208.0000000000 4 1192.0000000000 >>> teacher_match_list[0].winner.elo = 3000 >>> print_elo(teacher_match_list) 4 3000 # Object 4 2 1192.0000000000 5 1208.0000000000 2 1192.0000000000 5 1208.0000000000 4 1192.0000000000 # Object 4 >>> I solved this problem like so: def unify_refrences(match_list): """Makes each unique refrence to a model instance non-unique. In cases where multiple model instances are being used django creates a new object for each model instance, even if it that means creating the same instance twice. If one of these objects has its state changed any other object refrencing the same model instance will not be updated. This method ensure that state changes are seen. It makes sure that variables which hold objects pointing to the same model all hold the same object. Visually this means that a list of [var1, var2] whose internals look like so: var1 --> object1 --> model1 var2 --> object2 --> model1 Will result in the internals being changed so that: var1 --> object1 --> model1 var2 ------^ """ match_dict = {} for match in match_list: try: match.winner = match_dict[match.winner.id] except KeyError: match_dict[match.winner.id] = match.winner try: match.loser = match_dict[match.loser.id] except KeyError: match_dict[match.loser.id] = match.loser My question: Is there a way to solve the problem more elegantly through the use of QuerySets without needing to call save at any point? If not, I'd like to make the solution more generic: how can you get a list of the foreign keys on a model instance or do you have a better generic solution to my problem? Please correct me if you think I don't understand why this is happening.

  • How to auto-generate externs for the Google Closure Compiler

    - by ivo
    Suppose you are working in a javascript project with several external library dependencies, and want to compile your sources using the Google Closure Compiler in ADVANCED_OPTIMIZATIONS mode. Since in this mode the compiler will rename your code calls to the external libraries objects and functions, you must provide externs, to prevent this renaming from happening. But, it is a lot of work to produce the externs by hand, so, what is the best way to auto-generate the appropriate extern from a given javascript lib?

  • XAMPP or MAMP on Mac OS X 10.6.2 (Snow Leopard)

    - by Steve
    I just bought a new MacBook Pro which comes with Snow Leopard 10.6.2 (Mac OS X 10.6.2). I am used to using XAMPP as my local development server on XP. Since Mac OS X is based on Unix, I was thinking on activating/installing all the necessary stuff as I would normally do on Linux. However, I am not quite ready to be playing around with the system at this point so having an external package would be a nice temporary solution I think. The question is whether I should go with MAMP or XAMPP. Does anybody have any suggestions? The Pro and Cons I suppose. As far as I know, Mac OS X comes with Apache2 and PHP5. Would MAMP or XAMPP modify the existing Apache and PHP installation? Any comments on how I should proceed? PS: Eventually I would use the default installation of Apache and PHP, and install a binary package of MySQL but time for development is an essence and I don't have time to familiarize myself with Mac OS X.

  • Load HTML frames in a specific order without back button problems?

    - by Joergen Bech
    I have a web page that uses a frameset. Due to scripting and object dependencies, I need to load the frames in a specific order. I have used this example as a template: The JavaScript Source: Navigation: Frames Load Order This loads an empty page in place of the page I need to load last, then replaces it with the correct page after the first page has loaded. However: I also need to use the browser Back button. If you run the sample at the above link, let both frames load, then click the Back button, the top frame reverts to the temporary blank page. It is then necessary to click the Back button again to navigate to the page before the frameset. Is there a way to force frames to load in a specific order without this Back button behavior - or a way to force the Back button to skip the empty page? This needs to work with Internet Explorer 6 and 7 and preferably with Firefox 3 as well.

  • Deleting object in function

    - by wrongusername
    Let's say I have created two objects from class foo and now want to combine the two. How, if at all possible, can I accomplish that within a function like this: def combine(first, second): first.value += second.value del second #this doesn't work, though first.value *does* get changed instead of doing something like def combine(first, second): first.value += second.value in the function and putting del second immediately after the function call?

  • Factory Girl sequence fails under autospec

    - by John
    I have this Factory: Factory.define :email_address do |e| e.sequence(:address) { |n| "factory_#{n}@example.com" } e.validated true end When I run my specs with rake spec, it works fine. When I run autospec, it fails right away, claiming that the email address is being used twice in two different objects (there is a validation which restricts this). Why is it behaving differently under autospec? Thanks, John

  • SimpleRepository auto migrations with indexes

    - by scott
    I am using subsonic simplerepo with migrations in dev and it makes things pretty easy but I keep running into issues with my nvarchar columns that have an index. My users table has an index defined on the username column for obvious reasons but each time I start the project subsonic is doing this: ALTER TABLE [Users] ALTER COLUMN Username nvarchar(50); which causes this: The index 'IX_Username' is dependent on column 'Username'.ALTER TABLE ALTER COLUMN Username failed because one or more objects access this column Is there any way around this issue?

  • Create a user-defined aggregate without SQL CLR

    - by David Pfeffer
    I am planning on deploying a database to SQL Azure, so I cannot use the SQL CLR. However, I have a need to create an aggregate function -- in my case, I need to STUnion a bunch of Geography objects together. (Azure is expected to support Spatial by June.) Is there another way to accomplish this, without making use of the CLR, in a query? Or do I have to create a UDF that will take a table as a parameter and return the aggregate?

  • IE form input data disappear after browser refresh

    - by RWW
    Hi, I'm trying to achieve sticky forms without PHP. My setup is AJAX like javascript. The back/forward work fine on both IE and FF, but refresh only works on FF, not IE. Doesn't matter what cache options I use, I've even set IE's temporary files option to never check for updates, and the input value is gone after page refresh(the refresh button or F5) I've read many posts where people have the opposite problem, and do not want form data to persist across page refresh, and never read from browser cache, but I do. Any help is appreciated, thanks!
