• Create Django formset wihtout multiple queries

  - by Martin

  I need to display multiple forms (up to 10) of a model on a page. This is the code I use for to accomplish this. TheFormSet = formset_factory(SomeForm, extra=10) ... formset = TheFormSet(prefix='party') return render_to_response('template.html', { 'formset' : formset, }) The problem is, that it seems to me that Django queries the database for each of the forms in the formset, even though the data displayed in them is the same. Is this the way Formsets work or am I doing something wrong? Is there a way around it inside django or would I have to use JavaScript for a workaround?

• Unix file naming convention for effective tab completion?

  - by thebossman

  I feel like I often name files in such a way that my computer constantly beeps while I program because the tab completion is ambiguous. Before doing a lot of Unix programming, I tended to name related files with the same prefix to indicate their relation. Now I must re-think my approach to folder and file structures and names to program more effectively. What heuristics or rules do you apply when programming to simplify tab completion? Do you use any tools to make tab completion smoother (e.g., emacs icicles)?

• Django admin urls return INVALID REQUEST! - Django

  - by RadiantHex

  Hi folks, my admin urls are sat behind a prefix by doing the following. 1# (r'^admin/', include(admin.site.urls)), is placed within urls_core.py 2# (r'^api/', include('project.urls_core')), is palced within urls.py All admin URLs work fine except app indexes. If I go to any URL such as: /api/admin/core/ /api/admin/registration/ /api/admin/users/ /api/admin/filters/ I receive 'INVALID REQUEST' as my response. Status code is 200 (OK) though. I have never received this error message before. Does anyone have a clue? Thanks guys!

• Jing + swfobject 2.2 = big video in small popup

  - by consultutah

  I am trying to use swfobject 2.2 to display an swf, but the swf won't scale to fit the div that I'm putting it in. You can see what I've got here by clicking on the "Take the product tour" button. Here is the code to generate both the impromptu popup and the sfobject: $.prompt("<div id='flashContent'>Please wait...</div>", { prefix: "tour", top: "2%", buttons: {} }); var flashvars = { scale: "showAll" }; var params = { scale: "showAll"}; var attributes = {}; swfobject.embedSWF("/content/tour.swf", "flashContent", "800", "600", "9.0.0", "expressInstall.swf", flashvars, params, attributes); If, after the flash loads, I right-click and select "Show All", it appears correct. Any ideas on what I am doing wrong? I've verified that it doesn't matter whether I'm using impromptu or not. Thank you,

• Is this an F# quotations bug?

  - by ControlFlow

  [<ReflectedDefinition>] let rec x = (fun() -> x + "abc") () The sample code with the recursive value above produces the following F# compiler error: error FS0432: [<ReflectedDefinition>] terms cannot contain uses of the prefix splice operator '%' I can't see any slicing operator usage in the code above, looks like a bug... :) Looks like this is the problem with the quotation via ReflectedDefinitionAttribute only, normal quotation works well: let quotation = <@ let rec x = (fun() -> x + "abc") () in x @> produces expected result with the hidden Lazy.create and Lazy.force usages: val quotation : Quotations.Expr<string> = LetRecursive ([(x, Lambda (unitVar, Application (Lambda (unitVar0, Call (None, String op_Addition[String,String,String](String, String), [Call (None, String Force[String](Lazy`1[System.String]), [x]), Value ("abc")])), Value (<null>)))), (x, Call (None, Lazy`1[String] Create[String](FSharpFunc`2[Unit,String]), [x])), (x, Call (None, String Force[String](Lazy`1[String]), [x]))], x) So the question is: is this an F# compiler bug or not?

• XML::LibXML: How to write a xpath with qualified name?

  - by sid_com

  I've found this on http://www.perlmonks.org/?node_id=606909 looking by qualified name ... In this case you can call findnodes method on any node, you don't need the XML::LibXML::XPathContext with its prefix = namespace mapping: $doc-findnodes('///info/fooTransaction/transactionDetail/[name() = "histFile:transactionSummary"]/*'); In which way I have to edit my xpath to get my script working without XPathContext? #!/usr/bin/env perl use warnings; use strict; use 5.012; use XML::LibXML; my $parser = XML::LibXML->new; $parser->recover_silently( 1 ); my $doc = $parser->parse_file( 'http://www.heise.de/' ); my $xc = XML::LibXML::XPathContext->new( $doc->getDocumentElement ); $xc->registerNs( 'xmlns', 'http://www.w3.org/1999/xhtml' ); my $nodes = $xc->findnodes( '//xmlns:h2/xmlns:a' ); for my $node ( $nodes->get_nodelist ) { say $_->getName, '=', $_->getValue for $node->attributes; }

• How to create a custom yaml config file in Symfony

  - by Guillaume Flandre

  What I want to do is quite simple: store data in a custom config file that I want to read later on. I created my file something.yml that I put in the global config directory. It looks like that: prod: test: ok dev: test: ko all: foo: bar john: doe Then I copied the config_handlers.yml and also put it in the config directory and added the following at the top of the file: config/something.yml: class: sfDefineEnvironmentConfigHandler param: prefix: something_ But if I'm calling sfConfig::get("something_foo"); I keep getting NULL. What did I do wrong? I just want to read values, so no need to create a custome config handler, right? I've read the doc here: http://www.symfony-project.org/book/1_2/19-Mastering-Symfony-s-Configuration-Files even though I'm running 1.4 (I don't think that changed since then). Edit: Of course I can use sfYaml::load() but I'd like to do things in a better way.

• Avoiding thumbnail name collisions with sorl-thumbnail

  - by Owen Nelson

  Understanding that I should probably just dig into the source to come up with a solution, I'm wondering if anyone has come up with a tactic for dealing with this. In my project, I have a lot of images being generated outside of the application. I'm isolating them on the filesystem based on a model's pk. For example, a model instance with a pk of 121 might have the following images: .../thumbs/1/2/1/img.1.jpg .../thumbs/1/2/1/img.2.jpg ... .../thumbs/1/2/1/img.27.jpg Since the image filenames themselves are not guaranteed to be unique, I'm looking for a way to inform sorl (at runtime) that I'd like to prefix thumbs for this model with the instance pk value. Is this even possible without patching sorl?

• How to do a STAR search in LINQ

  - by aNui

  I'm not sure about clarity of the STAR word. I'm implementing a search method using linq-to-object in c#. And I want to do a search with * (star) operator like most of search apps or web can do. e.g. If I typed "p*", results should be everything starting with "p". And it should work for prefix star, suffix star or star in the middle. And it would be great if the search can do with "-" (minus/NOT) operator or "+" (plus/OR) operator or "AND" operator Thanks in advance.

• Using two namespaces when defining a new xml file (XDocument, XElement, XAttribute)

• Cabal: Odd Error Message + Lack of Documentation

  - by voxcogitatio

  So I recently installed cabal (from the default binary of ArchLinux). I then tried to upgrade cabal as a user: cabal upgrade Cabal --user --prefix=$USER Resolving dependencies... cabal: fromFlag NoFlag. Use fromFlagOrDefault What I've already done: Googled the error message. Turned up the cabal source and little else. Looked at haskell-wiki on cabal-install. Looked through this guide. So basically I'm wondering: What's up with the error message? Could anyone point me in the direction of a cabal tutorial?

• How to create an eclipse plug-in?

  - by Amir Rachum

  I've decided that as a pet project meant for learning, I would create a new Eclipse plug-in that, for a given class, takes all private member names and adds a prefix to their name (it doesn't matter to me if it can already be done or not, this is meant to be a learning experience). I have never developed an Eclipse plug-in and I'm not sure where to begin. Do I need to install some application for this development? How does it work? Where do I begin? I did a Google search but all the tutorials and results I found were old and referred to antiquated versions of Eclipse, so I'm not sure if they're still accurate.

• Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.

  I get the following error in Chrome every time I try to run my script on a Linux server: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. In Firefox it just shows a blank white page.

• how to get namespace prefixes from XML document, using MSXML ?

  - by KaluSingh Gabbar

  For example, In this document < ?xml version="1.0" ? > < SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns1="http://opcfoundation.org/webservices/XMLDA/1.0/" xmlns:ns2="Service"> < SOAP-ENV:Body id="_0" > if I need to select the element "Body", I need to know the prefix "SOAP-ENV". How can I get that? getting a root element and slicing the colon (:) off seems a dirty idea to me, I am sure there should be a neat way to do that. Google does not help (may be I am not searching for the right thing).

• AES Encryption. From Python (pyCrypto) to .NET

  - by Why

  I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

• When I mix JSTL 1.0 and JSTL 1.1 taglib declarations, it causes a ParseException on some of my serve

  - by sangfroid

  Hello all, When I mix JSTL 1.0 and JSTL 1.1 taglib declarations, it causes a ParseException on some of my servers, but not all of them. Here is the block of code that's giving me trouble : <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> <c:set var="TEXTVARIABLE">|STRINGOFTEXT|</c:set> <c:set var="OTHERTEXTVARIABLE">${fn:contains(TEXTVARIABLE, '|STRINGOFTEXT|')}</c:set> And here is the exception : javax.servlet.jsp.JspException: com.caucho.jsp.JspLineParseException: /WEB-INF/jsp/online/system/modules/com.MYCOMPANY.marketing/templates/common/MY_JSP_PAGE.jsp:1: tag = 'out' / attribute = 'value': An error occurred while parsing custom action attribute "value" with value "${fn:contains(TEXTVARIABLE, '|STRINGOFTEXT|')}": org.apache.taglibs.standard.lang.jstl.parser.ParseException: EL functions are not supported. However, everything works fine if I change the URI for the core declaration to http://java.sun.com/jsp/jstl/core So here's the really weird part : for some reason, mixing 1.0 and 1.1 taglib declarations only causes an exception on two of my servers -- my staging server and my production server. It causes no problems at all on my local machine or my development server. Why is this? What could possibly be causing this difference in behavior? The three servers are extremely similar in setup and configuration. The JSP page is being served up by OpenCMS, and I'm using the Caucho's Resin webserver. I understand that you don't know how my servers or CMS are set up, but really, what I'm looking for is ideas. Any ideas at all would help -- this problem has been driving me absolutely batty. Even if you don't know what could be causing the problem, if you have any suggestions at all for how I could approach the problem, that would be extremely helpful. I just don't understand what could cause this difference in behavior between my servers. For reference, here's the full stack trace : javax.servlet.jsp.JspException: com.caucho.jsp.JspLineParseException: /WEB-INF/jsp/online/system/modules/com.MYCOMPANY.marketing/templates/common/MY_JSP_PAGE.jsp:1: tag = 'out' / attribute = 'value': An error occurred while parsing custom action attribute "value" with

• GWT i18n - Plural Forms doesn't work at all?

  - by PEZ

  I'm using GWT internationalization Messages. The documentation for Plural Forms says this should work: @DefaultMessage("{0} {1,number} hours {2}") @PluralText({"one", "an hour"}) String hours(String prefix, @PluralCount int count, String suffix); Well, it doesn't. Whatever value of count it still delivers DefaultMessage (e.g. "1 hours ago"). Same if I use a .properties file: hours[one]=an hour hours[few]=some hours hours={0} {1,number} hours {2} Is there a bug in the docs or in GWT (I'm using GWT 2.0.3) or in me? If any of the two former, anyone knows of a workaround?

Is there a way to loop through each tag seperate? var partyElements = from party in xmlDoc.Descendants("Party") select new { Name = party.Attribute("id").Value, PartyTypeCode = party.Element("PartyTypeCode").Value, FullName = party.Element("FullName").Value, GovtID = party.Element("GovtID").Value, };

• Two fields with the same name

  - by H. Abraham Chavez

  I have a ViewModel class to encapsulate "Personal" and "Business" models. My problem is that both models have a property called "Email" and the model binding is not able to make a distinction between the too. I read that [Bind(Prefix = ... is used to resolved this issue, but I have not been able to see a concise example on how to achieve this. SO community please help. public class BusinessFormViewModel { public Business Business { get; set; } public ContactPerson ContactPerson { get; set; } public BusinessFromView(Business business, ContactPerson contactPerson) { Business = business; ContactPerson = contactPerson; } }

• Thinking Sphinx - sorting by a string attribute gets out of sync when changes are made

  - by Scott Brown

  I have a "restaurants" table with a "name" column. I've defined the following index: indexes "REPLACE(UPPER(restaurants.name), 'THE ', '')", :as => :restaurant_name, :sortable => true ... because I want to sort the restaurant names without respect to the prefix "The ". My problem is that whenever one of these records is updated (in any way) the new record jumps to the top of the sort order. If another record is updated, it also jumps ahead of the rest. I end up with two lists: a list of restaurants that have been updated since the last re-indexing and a list of those that haven't. Each respective list is in alphabetical order, but I don't understand why the overall list is getting segregated this way. I do have a delayed delta index set up, and I assume the issue is related to this.

• DurandalJS vs AngularJS?

  - by Zach

  I'm looking for a JS framework to build an SPA and found DurandalJS and AngularJS. Can anyone compare these two frameworks? I did find many articles that compares AngularJS and KnockoutJS, and they say AngularJS is more than data binding, so I think DurandalJS may be the one to compare. I did a little research on AngularJS, it is good but one thing is bad: the $ prefix does not work when minified, although there is an ugly workaround. And someone said Twitter Bootstrap does not work well with it (I didn't check). For DurandalJS, I still cannot find the samples (http://durandaljs.com/documentation/Understanding-the-Samples/), so it's hard to say. PS: are they working well with TypeScript? Best regards, Zach

• XSD NewDataSet Namespace?

  - by Ian

  I'm running XSD on an XML file and getting something strange. Depending on the depth of elements it produces a 'NewDataSet' element which will then is prefixed in Visual Studio to my auto-generated classes which is something I don't want. I've got quite a complex structure and am just trying to add a simple version element or attribute which is causing the problem. The simplest demo I could come up with is this. <A> <B>Text</B> </A> Running this through XSD says there is an element called 'NewDataSet' which may or may not appear and will prefix namespaces. <A> <B> <C>Text</C> </B> </A> This example works as expected and there is no magic 'NewDataSet' element in the generated XSD file.

• PostGIS - can't create spatially-enabled database

  - by itgorilla

  I'm using Ubuntu 10.10, PostgreSQL 9.0 and PostGIS 1.5. I've installed PostGIS 1.5 from: https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable I used PPA first then the command: sudo apt-get install postgis to install postgis. I've been following these instructions to create a spatially-enabled database: http://ostgis.refractions.net/docs/ch02.html#id2630100 I got to the point where it's saying: Now load the PostGIS object and function definitions into your database by loading the postgis.sql definitions file (located in [prefix]/share/contrib as specified during the configuration step). psql -d [yourdatabase] -f postgis.sql Well, there is no postgis.sql on my server after the installation. I did an sudo updatedb to make sure I can find postgis.sql but it's not there. Any ideas? Thank you!
