• Django admin interface upload failing on request data read error

  - by Jake

  Hi All, This is an updated version of an old question I asked. I've now done a lot more testing, plus the old question got hijacked. I'm getting a request data read error when trying to upload files to the Django admin interface. Files under about 150k work, but bigger files always fail and almost always at around 192k (that's 3 chunks) completed, sometimes at around 160k. The Exception I get is below. File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 405, in read return self._file.read(num_bytes) IOError: request data read error I've tried Chrome and Firefox on Windows and Firefox on Mac - Same results. I can upload to other sites so I don't think it's my connection. I'm running python 2.4, django 1.1, mod_wsgi, on CentOS (a media temple DV server) Locally it's fine (Django development server) Everything I've found on this issue says it's a mod_python issue and that changing to mod_wsgi will fix it, but I am running mod_wsgi. Can anyone help?

• Dependency Injection: How to maintain multiple configurations?

  - by Malax

  Hi StackOverflow, Lets assume we've build a system with a DI framework which is working quite fine. This system currently uses JMS to "talk" with other systems not maintained by us. The majority of our customers like the JMS approach and uses it according to our specification. The component which does all the messaging is injected with Spring into the rest of the application. Now we got the case that one customer cannot implement the JMS solution and want to use another messaging technology. Thats not a problem because we can simply implement a messaging service using this technology and inject it in the rest of the application. But how are we supposed to handle the deployment and maintenance of the configuration? Since the application uses Spring i could imagine to check in all the configurations i have for this application and the system administrator could start the application and passing the name of the DI XML file to specify which configuration should be loaded. But... it just don't feel right. Are there any solutions for such cases available? What are the best-practices you use? I could even imagine more complex scenarios which do not contain only one service substitution... Thanks a lot!

• Converting delimited string to multiple values in mysql

  - by epo

  I have a mysql legacy table which contains an client identifier and a list of items, the latter as a comma-delimited string. E.g. "xyz001", "foo,bar,baz". This is legacy stuff and the user insists on being able to edit a comma delimited string. They now have a requirement for a report table with the above broken into separate rows, e.g. "xyz001", "foo" "xyz001", "bar" "xyz001", "baz" Breaking the string into substrings is easily doable and I have written a procedure to do this by creating a separate table, but that requires triggers to deal with deletes, updates and inserts. This query is required rarely (say once a month) but has to be absolutely up to date when it is run, so e.g. the overhead of triggers is not warranted and scheduled tasks to create the table might not be timely enough. Is there any way to write a function to return a table or a set so that I can join the identifier with the individual items on demand?

• How to handle multiple delegates

  - by mac_55

  I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

• multiple redirect??

  - by Ryan Pitts

  Ok, i won't go into the full details (too much to explain) but here is what i am trying to do. I have a button on a webpage (we'll call page-1) that links to a page (we'll call it page-2). This page opens in the same window. However, i need the page (page-2) that opens to open up a new window with another page (we'll call this one page-3) when it loads. So virtually when you click the initial button (on page-1) it will go to a new page (page-2) AND a window will open as well with a different page (page-3). This is where it gets tricky. I need page-2 to automatically redirect back to page-1 after it launches page-3. Is this possible and if so, how?? Could it be a JQuery thing? Please just give some answers...i know this is way crazy and a huge workaround - but this is my last resort for this particular website. I have to do it this way because of the lack of control over some of the code.

• Powershell GUI: Adding multiple instances of .tooltipseperate to menu

  - by obious

  So, I'm having a problem whereby for some reason I can only add one instance of a .tooltipseperator to a drop down menu. E.g. I have to create a new .tooltipseperator if I want to add another to a different menu list. I have this: $seperator = new-object System.Windows.Forms.Toolstripseparator $seperator1 = new-object System.Windows.Forms.Toolstripseparator which correlates to this: [Void]$packages_menu_bar.DropDownItems.Add($seperator1) [Void]$packages_menu_bar.DropDownItems.Add($Remove_from_AD) [Void]$process.DropDownItems.Add($Kill_process) [Void]$process.DropDownItems.Add($seperator) My question is this: how can I add the same instance on a .tooltipseperater to different menu items? Some sort of array? Thanks

• Saving multiple objects in a single call in rails

  - by CaptnCraig

  I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

• Equality Comparison with Multiple Instances/IEqualityComparer problems in LINQ

  - by Stacey

  This is similar to my last question; but from a different angle. http://stackoverflow.com/questions/2792393/see-if-item-exists-once-in-enumerable-linq Given the following set of items, and lists containing them... Item 1 Item 2 Item 3 Item 4 Item 5 class Item { string Name { get; set; } } List<Item> available = new List<Item>() { Item 1 Item 1 Item 2 Item 3 Item 5 } List<Item> selected = new List<Item>() { Item 1 Item 2 Item 3 } I need to make a third List that has everything from "available", except what is in "selected". However 'Item 1' is in 'available' twice, but only in 'selected' once. Since they are instances of the same item, I am having trouble figuring out the appropriate logic to accomodate this. The final array should look like... List<Item> selectable = new List<Item>() { Item 1 Item5 }

• Real-time aggregation of files from multiple machines to one

  - by dmitry-kay

  I need a tool which gets a list of machine names and file wildcards. Then it connects to all these machines (SSH) and begins to monitor changes (appendings to the end) in each file matched by wildcards. New lines in each such file are saved to the local machine to the file with the same name. (This is a task of real-time log files collecting.) I could use ssh + tail -f, of course, but it is not very robust: if a monitoring process dies and then restarts, some data from remote files may be lost (because tail -f does not save the position at which it is finished before). I may write this tool manually, but before - I'd like to know if such tool already exists or not.

• get SSL Broken pipe error when try to make push notification

  - by emagic

  We develop an iPhone app, and have push notification for development and ad hoc version working properly. But when we try to send push notification to real user devices in our database, we got SSL connection reset, then Broken pipe error. We think maybe there are too many devices in our database (more than 70000), so it is failed to send all messages at the same time. So we try to send messages to 1000 devices once, but still got this "Broken pipe" error for around 100 messages. And we are not sure whether the messages have been send. Any suggestion?

• Multiple levels of 'collection.defaultdict' in Python

  - by Morlock

  Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

• Modeling multiple polymorphic relationships using Hibernate

  - by f-potter

  Ruby on Rails has polymorphic relations which are really useful for implementing functionality such as commenting, tagging and rating to name a few. We can have a comment, tag or rating class which has a many to one polymorphic relationship with a commentable, taggable and rateable object. Also, a given domain object can choose to implement any combination of such relations. So, it can for example be commentable, taggable and rateable at the same time. I couldn't think up of a straightforward way to duplicate this functionality in Hibernate. Ideally, there would be a Comment class which will have a many to one relationship with a Commentable class and a Commentable class will conversely have a one to many relationship with Comments. It will be ideal if the concrete domain classes can inherit from a number of such classes, say Commentable and Taggable. Things seem a little complicated as a Java class can only extend one other class and some code might end up being duplicated across a number of classes. I wanted to know what are the best practices for modeling such relationships neatly and concisely using Hibernate?

• Howto troubleshoot vb6 dll 800a01ad error in c# application

  - by phq

  I have a dll that I created from a VB6 project that I am now using in a c# project. This has worked before but now when I try to return to the c# project to fix a bug, the program get a COMException stating roughly translated: Could not create an instance of COM-component with CLSID {085E3494-9F78-47D5-B0E6-FA460FD3CBED} from IClassFactory because of the following error: 800a01ad. So I try to create a new empty c# project with only one line in the main function: OurNamespace.OurClass foo = new OurNamespace.OurClass(); Which fails with the same error. I have registered the dll but that did not change the outcome of the problem. The problem only occurs on the machine I am currently at, still I'm interested to understand the problem so that I know how to fix it if it occurs on a customers computer.

• Jasper error: Caused by SQLServerException: Transaction (Process ID 58) was deadlocked on thread | c

  - by Saky

  I got the above error in my jasper report mail. The query that is used in the report is quite complicated (for me). Reading different posts I conclude that to solve this the I have to change the query to SET TRANSACTION ISOLATION LEVEL REPEATABLE READ GO BEGIN TRANSACTION ... my query ... COMMIT TRANSACTION ? I wonder if this is the correct way to solve the error and that if it has any side effects? Has it happened to anyone in the Jasper reports? Does anyone know if there is a better solution exist to the problem? (Although that I have not yet tested the above solution, if anyone can give any insight on this will be helpful.)
