  • Wordpress XML-RPC call from Objective C: wp.newComment

    - by radesix
    I'm using Eric Czarny's Cocoa XML-RPC framework to make a call to the Wordpress API's. I've downloaded the sample app from Wordpress which gives some good examples. Unfortunately the good examples are for every call EXCEPT wp.newComment. I'm trying to post a comment using the code below and I keep getting an error with a localized description that tells me to check my input parameters. I've checked and rechecked and I don't understand what is wrong. Any ideas? NSDictionary *commentStructure = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithInt:0], @"comment_parent", @"xmlrpc anonymous comments plugin now enabled", @"content", @"Test Author", @"author", @"http://iphone.someurl.com", @"author_url", @"[email protected]", @"author_email", nil]; NSArray *args = [NSArray arrayWithObjects:[NSNumber numberWithInt:0], @"", @"", [NSNumber numberWithInt:[self.parentFeedItem.postID intValue]], commentStructure, nil]; // the param(s) NSString *server = [[[NSString alloc] initWithString:@"http://www.someurl.com/xmlrpc.php"] autorelease]; // the server NSString *method = [[[NSString alloc] initWithString:@"wp.newComment"] autorelease]; // the method XMLRPCRequest *request = [[XMLRPCRequest alloc] initWithHost:[NSURL URLWithString:server]]; [request setMethod:method withObjects:args]; id response = [self executeXMLRPCRequest:request]; [request release]; if( [response isKindOfClass:[NSError class]] ) { //return nil; NSLog(@"There was a problem"); NSLog([response localizedDescription]); }

  • Error // Usage: rails new APP_PATH [options] // when running 'rails server'

    - by madphill

  • Who architected / designed C++'s IOStreams, and would it still be considered well-designed by today'

    - by stakx
    First off, it may seem that I'm asking for subjective opinions, but that's not what I'm after. I'd love to hear some well-grounded arguments on this topic. In the hope of getting some insight into how a modern streams / serialization framework ought to be designed, I recently got myself a copy of the book Standard C++ IOStreams and Locales by Angelika Langer and Klaus Kreft. I figured that if IOStreams wasn't well-designed, it wouldn't have made it into the C++ standard library in the first place. After having read various parts of this book, I am starting to have doubts if IOStreams can compare to e.g. the STL from an overall architectural point-of-view. Read e.g. this interview with Alexander Stepanov (the STL's "inventor") to learn about some design decisions that went into the STL. What surprises me in particular: It seems to be unknown who was responsible for IOStreams' overall design (I'd love to read some background information about this — does anyone know good resources?); Once you delve beneath the immediate surface of IOStreams, e.g. if you want to extend IOStreams with your own classes, you get to an interface with fairly cryptic and confusing member function names, e.g. getloc/imbue, uflow/underflow, snextc/sbumpc/sgetc/sgetn, pbase/pptr/epptr (and there's probably even worse examples). This makes it so much harder to understand the overall design and how the single parts co-operate. Even the book I mentioned above doesn't help that much (IMHO). Thus my question: If you had to judge by today's software engineering standards (if there actually is any general agreement on these), would C++'s IOStreams still be considered well-designed? (I wouldn't want to improve my software design skills from something that's generally considered outdated.)

  • Great examples of self-paced labs and exercises

    - by Mayo
    It is probably a safe bet that many of us are what they call Tactile / Kinesthetic Learners meaning that we learn best when we are physically doing something as opposed to listening to an online tutorial or reading a book. My goal with this question is to derive a list of books or online resources that serve as superb examples of self-paced programming labs and exercises. For example, I was extremely impressed with the SportsStore exercise in Steven Sanderson's Pro ASP.NET MVC Framework. The exercise spanned multiple chapters and gradually introduced new topics. I was also impressed with the materials associated with the Windows Azure Boot Camp. The demos and lab materials, accessible through the website, allow us to practice and reinforce what we can read about in articles and books. Please list any examples you might have, one per submission, below. The question is language/platform agnostic. Suggestions can be generic or specific to a given technology (PHP, SQL Server, Azure, Flash, Objective C, etc.). I only ask that the answers pertain to labs and exercises that relate to programming. My hope is that the best answers will float to the top allowing developers to review the top answers and find another programming topic that can be learned through example.

  • Spring MVC: How to resolve the path to subdirectories of the root 'JSP' folder in a web application

    - by chrisjleu
    What is a simple way to resolve the path to a JSP file that is not located in the root JSP directory of a web application using SpringMVCs viewResolvers? For example, suppose we have the following web application structure: web-app |-WEB-INF |-jsp |-secure |-admin.jsp |-admin2.jsp index.jsp login.jsp I would like to use some out-of-the-box components to resolve the JSP files within the jsp root folder and the secure subdirectory. I have a *-servlet.xml file that defines: an out-of-the-box, InternalResourceViewResolver: <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> a handler mapping: <bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/index.htm">urlFilenameViewController</prop> <prop key="/login.htm">urlFilenameViewController</prop> <prop key="/secure/**">urlFilenameViewController</prop> </props> </property> </bean> an out-of-the-box UrlFilenameViewController controller: <bean id="urlFilenameViewController" class="org.springframework.web.servlet.mvc.UrlFilenameViewController"> </bean> The problem I have is that requests to the JSPs in the secure directory cannot be resolved, as the jspViewResolver only has a prefix defined as /jsp/ and not /jsp/secure/. Is there a way to handle subdirectories like this? I would prefer to keep this structure because I'm also trying to make use of Spring Security and having all secure pages in a subdirectory is a nice way to do this. There's probably a simple way to acheive this but I'm new to Spring and the Spring MVC framework so any pointers would be appreciated.

  • protobuf-net v2 alpha - problems with Dictionary<string,string>?

    - by Steve
    I was using a version of v2 of protobuf-net from a few weeks ago quite successfully. (I want to use V2 due to the speed of the pre-compiled serializer running on the Compact Framework.) Everything worked great until I tried to serialize an object with a property of type Dictionary. I received the following error: {"No serializer defined for type: System.Collections.Generic.KeyValuePair`2[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"} It looked like there were recent changes made to improve Dictionary support, so I grabbed the latest code from today. After building the CF3.5 and FF3.5 dlls, I tried again. Now I get a different error "The model cannot be changed once frozen." If I remove the ProtoMember attribute from the Dictionary property all seems to work well. Has anyone succcessfully used a Dictionary in v2 of protobuf-net? Is this still too early of a release to be using? My speed tests showed v2 being twice as fast, does that seem accurate (validating my desire to use the less stable v2 pre-alpha bits.)

  • Continuous Integration with 64-bit Sharepoint and TFS 2008?

    - by Hirvox
    I've set up a 64-bit TFS 2008 build server with Sharepoint, continuous integration and out-of-the-box MSTest. Unit tests for plain business logic classes run just fine and test results are published into TFS. However, any test that uses Sharepoint's API fails horribly, SPFarm.Local returning null and so on. Is there a way to fix this? The tests run fine in an otherwise identical 32-bit development environment (Windows Server 2008 under Hyper-V, Sharepoint patched up to June 2009 cumulative update) from both Visual Studio and command line, so the problem is not about improper use of SPContext.Current or any other part of the API that needs to be run in a web server context. I've ruled out permissions issues, because the build agent account can deploy the solution and create site collections just fine with stsadm. The next culprit could be that the unit tests were being run with a 32-bit process, which couldn't access the 64-bit Sharepoint API properly. I tried a workaround, but it has the side effect of disabling TFS support in MSTest. Do I have to wait for 2010 versions of MS tools (and hope for the best) or is there a third-party test framework available that runs natively in 64 bit and can publish test results into TFS 2008?

  • Run AppleScript with Elevated Privileges from Objective C

    - by cygnl7
    I'm attempting to execute an uninstaller (written in AppleScript) through AuthorizationExecuteWithPrivileges. I'm setting up my rights after creating an empty auth ref like so: char *tool = "/usr/bin/osascript"; AuthorizationItem items = {kAuthorizationRightExecute, strlen(tool), tool, 0}; AuthorizationRights rights = {sizeof(items)/sizeof(AuthorizationItem), &items}; AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights | kAuthorizationFlagPreAuthorize | kAuthorizationFlagInteractionAllowed; status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL); Later I call: status = AuthorizationExecuteWithPrivileges(authorizationRef, tool, kAuthorizationFlagDefaults, (char *const *)args, NULL); On Snow Leopard this works fine, but on Leopard I get the following in syslog.log: Apr 19 15:30:09 hostname /usr/bin/osascript[39226]: OpenScripting.framework - 'gdut' event blocked in process with mixed credentials (issetugid=0 uid=501 euid=0 gid=20 egid=20) Apr 19 15:30:12: --- last message repeated 1 time --- ...

(-1708) After researching this for a few hours my first guess is that Leopard somehow doesn't want to do what I'm doing because it knows it's in a setuid situation and blocks calls that ask about user-specific things in the applescript. Am I going about this all wrong? I just want to run the equivalent of "sudo /usr/bin/osascript ..." Edit: FWIW, the first line that causes the "execution error" is: set userAppSupportPath to (POSIX path of (path to application support folder from user domain)) However, even with an empty script (on run argv, end run and that's it) I still get the 'gdut' message.

  • Execute javascript on IIS server

    - by James Westgate
    I have the following situation. A customer uses JavaScript with jQuery to create a complex website. We would like to use JavaScript and jQuery on the server (IIS) for the following reasons: Skills transfer - we would like to use JavaScript and jQuery on the server and not have to use eg VB Script. / classic asp. .Net framework/Java etc is ruled out because of this. Improved options for search/accessibility. We would like to be able to use jQuery as a templating system, but this isn't viable for search engines and users with js turned off - unless we can selectively run this code on the server. There is significant investment in IIS and Windows Server, so changing that is not an option. I know you can run jScript on IIS using windows Script host, but am unsure of the scalability and the process surrounding this. I am also unsure whether this would have access to the DOM. Here is a diagram that hopefully explains the situation. I was wondering if anyone has done anything similar?

  • As a newbie, where should I go if I want to create a small GUI program?

    - by jimbmk
    Hello, I'm a newbie with a little experience writing in BASIC, Python and, of all things, a smidgeon of assembler (as part of a videogame ROM hack). I wanted to create small tool for modifying the hex values at particular points, in a particular file, that would have a GUI interface. What I'm looking for is the ability to create small GUI program, that I can distribute as an EXE (or, at least a standalone directory). I'm not keen on the idea of the .NET languages, because I don't want to force people to download a massive .NET framework package. I currently have Python with IDLE and Boa Constructor set up, and the application runs there. I've tried looking up information on compiling a python app that relies on Wxwidgets, but the search results and the information I've found has been confusing, or just completely incomprehensible. My questions are: Is python a good language to use for this sort of project? If I use Py2Exe, will WxWidgets already be included? Or will my users have to somehow install WxWidgets on their machines? Am I right in thinking at Py2Exe just produces a standalone directory, 'dist', that has the necessary files for the user to just double click and run the application? If the program just relies upon Tkinter for GUI stuff, will that be included in the EXE Py2Exe produces? If so, are their any 'visual' GUI builders / IDEs for Python with only Tkinter? Thankyou for your time, JBMK

  • Page_PreRender fires twice on first load in session

    - by awe
    I have an issue when I access the application, I notice that Page_PreRender is fired twice. This only happens the first time in a new session. It does not happen if I refresh the page, or on postbacks. I use .NET framework 3.5 and the built in ajax functionality. I think the problem is not related to img tag with empty src attribute as I have seen other posts has mentioned, because I see this in both FireFox and IE. The posts I saw about this stated that this was not a problem in IE. I have also searched and found no img tags with empty src in the generated page source, so it should not be this. I have also made a simple test page where I have included some of the functionality, and this does not happen. Here I have also tried to reproduce the empty src bug by including <img src="" /> on the page, but this does not trigger this problem. Have anyone any suggestions on what happens? Note: It is the entire page cycle that is firing twice, not just render.

  • Sending jQuery.ajax data simultaneous to a form submit

    - by dscher
    I have a bit of a conundrum. I have a form which has numerous fields. There is one field for links where you enter a link, click an add button, and the link(using jQuery) gets added to a link_array. I want this array to be sent via the jQuery.ajax method when the form is submitted. If I send the link_array using $.ajax like this: $.ajax({ type: "POST", url: "add_stock", dataType: "json", data: { "links": link_array } }); when the add link button is selected the data goes no problem to the correct place and gets put in the db correctly. If I bind the above function to the submit form button using $(#stock_form).submit(..... then the rest of the form data is sent but not the link_array. I can obviously pass the link array back into a hidden field in HTML but then I'd have to unpack the array into comma separate values and break the comma-separated string apart in PHP. It just seems 100X easier to unpack the Javascript array in PHP without an other fuss. So, how is it that you can send an array from javascript using $.ajax concurrent to the rest of the $_POST data in HTML? Please note that I'm using Kohana 3.0 framework but really that shouldn't make a difference, what I want to do is add this js array to the $_POST array that is already going. Thanks!

  • Generating All Permutations of Character Combinations when # of arrays and length of each array are

    - by Jay
    Hi everyone, I'm not sure how to ask my question in a succinct way, so I'll start with examples and expand from there. I am working with VBA, but I think this problem is non language specific and would only require a bright mind that can provide a pseudo code framework. Thanks in advance for the help! Example: I have 3 Character Arrays Like So: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] I would like to generate ALL possible permutations of the character arrays like so: XA1 XA2 XA3 XA4 XB1 XB2 XB3 XB4 YA1 YA2 . . . ZB3 ZB4 This can be easily solved using 3 while loops or for loops. My question is how do I solve for this if the # of arrays is unknown and the length of each array is unknown? So as an example with 4 character arrays: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] Arr_4 = [a,b] I would need to generate: XA1a XA1b XA2a XA2b XA3a XA3b XA4a XA4b . . . ZB4a ZB4b So the Generalized Example would be: Arr_1 = [...] Arr_2 = [...] Arr_3 = [...] . . . Arr_x = [...] Is there a way to structure a function that will generate an unknown number of loops and loop through the length of each array to generate the permutations? Or maybe there's a better way to think about the problem? Thanks Everyone!

  • Going from small to medium sized websites.

    - by Landitus
    I've been coding websites for a couple of years now, mostly in php and xhtml. I come from the design world, but I'm proud of doing standart compliant websites and great interfaces. Also used Wordpress and loved it. Most of the time there were really simple commercial websites, with no database included, where everything is done from scratch. Every page is parsed through an index?page=xxx and But I have a few prospects that are larger websites (let's call them 'medium sized websites') where I feel I'm lacking the following: How to dispach or render the pages (MVC controller instead of index?page=???) Proper page hierarchy and easy breadcrumbs implementation Auto generation of navigation menu, or an easy way to maintain them? Clean URLs Form validation Easy database support I really don't know if I should be looking into php scripts, and refine my skills or get into a CMS (like drupal) or a PHP framework. I found Wordpress very assuring and didn't feel trapped into crazy conventions, but I feel is not the right tool for this. I hate the CMS Page with the big textbox as I am used to code every page by hand my pages are not a title and a textbox. Got the feeling? My php skills are sort of medium/low still, but I would like to hear some thoughts of what I should learn to take the next step!

  • Why is Lua considered a game language?

    - by Hoffmann
    I have been learning about Lua in the past month and I'm absolutely in love with the language, but all I see around that is built with lua are games. I mean, the syntax is very simple, there is no fuss, no special meaning characters that makes code look like regex, has all the good things about a script language and integrates so painlessly with other languages like C, Java, etc. The only down-side I saw so far is the prototype based object orientation that some people do not like (or lack of OO built-in). I do not see how ruby or python are better, surely not in performance ( http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=lua&lang2=python ). I was planning on writting a web app using lua with the Kepler framework and Javascript, but the lack of other projects that use lua as a web language makes me feel a bit uneasy since this is my first try with web development. Lua is considered a kids language, most of you on stackoverflow probably only know the language because of the WoW addons. I can't really see why that is... http://lua-users.org/wiki/LuaVersusPython this link provides some insights on Lua against Python, but this is clearly biased.

  • Cannot read value from SYS_CONTEXT

    - by AppleGrew
    I have a PL/SQL procedure which sets some variable in user session, like the following:- Dbms_Session.Set_Context( NAMESPACE =>'MY_CTX', ATTRIBUTE => 'FLAG_NAME', Value => 'some value'); Just after this (in the same procedure), I try to read the value of this flag, using:- SYS_CONTEXT('MY_CTX', 'FLAG_NAME'); The above returns nothing. How did the DB lose this value? The weirder part is that if I invoke this proc directly from Oracle SQL Developer then it works. It doesn't work when I invoke this proc from my web application from callable statement. --EDIT-- Added an example as to how we are invoking the proc from our Java code. String statement = "Begin package_name.proc_name( flag_val => :1); END;"; OracleCallableStatement st = <some object by some framework> .createCallableStatement(statement); st.setString(1, 'flag value'); st.execute(); st.close();

  • Why does my IMultiBindingConverter get an array of strings when used to set TextBox.Text?

    - by mcohen75
    Hi- I'm trying to use a MultiBinding with a converter where the child elements also have a converter. The XAML looks like so: <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource localizedMessageConverter}" ConverterParameter="{x:Static res:Resources.RecordsFound}" > <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="ALIAS" Path="Alias" Mode="OneWay" /> <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="COUNT" Path="Count" Mode="OneWay" /> </MultiBinding> </TextBlock.Text> The problem I'm facing here is, whenever this is used with a TextBlock to specify the Text property, my IMultiValueConverter implementation gets an object collection of strings instead of the class returned by the IValueConverter. It seems that the ToString() method is called on the result of the inner converter and passed to the IMultiValueConverter. If used to specify the Content property of Label, all is well. It seems to me that the framework is assuming that the return type will be string, but why? I can see this for the MultiBinding since it should yield a result that is compatible with TextBlock.Text, but why would this also be the case for the Bindings inside a MultiBinding? If I remove the converter from the inner Binding elements, the native types are returned. In my case string and int.

  • Data Mappers, Models and Images

    - by James
    Hi, I've seen and read plenty of blog posts and forum topics talking about and giving examples of Data Mapper / Model implementations in PHP, but I've not seen any that also deal with saving files/images. I'm currently working on a Zend Framework based project and I'm doing some image manipulation in the model (which is being passed a file path), and then I'm leaving it to the mapper to save that file to the appropriate location - is this common practise? But then, how do you deal with creating say 3 different size images from the one passed in? At the moment I have a "setImage($path_to_tmp_name)" which checks the image type, resizes and then saves back to the original filename. A call to "getImagePath()" then returns the current file path which the data mapper can use and then change with a call to "setImagePath($path)" once it's saved it to the appropriate location, say "/content/my_images". Does this sound practical to you? Also, how would you deal with getting the URL to that image? Do you see that as being something that the model should be providing? It seems to me like that model should worry about where the images are being stored or ultimately how they're accessed through a browser and so I'm inclined to put that in the ini file and just pass the URL prefix to the view through the controller. Does that sound reasonable? I'm using GD for image manipulation - not that that's of any relevance. UPDATE: I've been wondering if the image resizing should be done in the model at all. The model could require that it's provided a "main" image and a "thumb" image, both of certain dimensions. I've thought about creating a "getImageSpecs()" function in the model that would return something that defines the required sizes, then a separate image manipulation class could carry out the resizing and (perhaps in the controller?) and just pass the final paths in to the model using something like "setImagePaths($images)". Any thoughts much appreciated :) James.

  • getting a tiled image collection on the iPad (deepzoom)

    - by Chris B
    I have a set of tiled image collections created via microsoft's deep zoom composer, and a silverlight app that currently consumes them for display via MultiScaleImage - it's all working pretty well - I'd just like to get some experience with iPad programming and have a couple of ideas for some ipad applications. All my ideas rely on me being able to display/manipulate these tiled image sets (on the iPad). I just picked up a iMac to facilitate this. I'm not seeing any objective-c / cocoa-touch libraries for this though, so am assuming I will have to roll my own. (Saw the seadragon ajax component, which is pretty slick, but I'm dealing with collections here, which it doesn't support. I would also like to roll this as a native app just to get the experience). The only open source project I found for displaying/manipulating the tiled image sets was Openzoom -a flash component. I'm not to familiar with actionscript either (python, java, c#, and c are the only languages I have really used), but briefly inspecting the code I didn't really have any issues with it and can probably use it for hints on how to swap the tiles in and out, etc.. But, as I'm pretty new to obj-c/cocoa-touch, some pointers in the right direction would be appreciated. 1) Are there any other projects out there I am missing, or is openzoom my best bet for some reference? 2) Should I be trying to do this display in the UIKit framework, or should I do it as an OpenGL display? 3) Any other suggestions/pointers that I didn't think to ask.

  • Need help in tuning a sql-query

    - by Viper
    Hello, i need some help to boost this SQL-Statement. The execution time is around 125ms. During the runtime of my program this sql (better: equally structured sqls for different tables) will be called 300.000 times. The average row count in the tables lies around 10.000.000 rows and new rows (updates/inserts) will be added with a timestamp each day. Data which are interesting for this particular export-program lies in the last 1-3 days. Maybe this is helpful for an index to create. The data i need is the current valid row for a given id and the forerunner datarow to get the updates (if exists). We use a Oracle 11g database and Dot.Net Framework 3.5 SQL-Statement to boost: select ID_SOMETHING, -- Number(12) ID_CONTRIBUTOR, -- Char(4 Byte) DATE_VALID_FROM, -- DATE DATE_VALID_TO -- DATE from TBL_SOMETHING XID where ID_SOMETHING = :ID_INSTRUMENT and ID_CONTRIBUTOR = :ID_CONTRIBUTOR and DATE_VALID_FROM <= :EXPORT_DATE and DATE_VALID_TO >= :EXPORT_DATE order by DATE_VALID_FROM asc; Here i uploaded the current Explain-Plan for this query. I'm not a database expert so i don't know which index-type would fit best for this requirement. I have seen that there are many different possible index-types which could be applied. Maybe Oracle Optimizer Hints are helpful, too. Does anyone has a good idea for tuning this sql or can point me in a right direction?

  • Python template engine

    - by jturo
    Hello there, Could it be possible if somebody could help me get started in writing a python template engine? I'm new to python and as I learn the language I've managed to write a little MVC framework running in its own light-weight-WSGI-like server. I've managed to write a script that finds and replaces keys for values: (Obviously this is not how my script is structured or implemented. this is just an example) from string import Template html = '<html>\n' html += ' <head>\n' html += ' <title>This is so Cool : In Controller HTML</title>\n' html += ' </head>\n' html += ' <body>\n' html += ' Home | <a href="/hi">Hi ${name}</a>\n' html += ' </body>\n' html += '<html>' Template(html).safe_substitute(dict(name = 'Arturo')) My next goal is to implement custom statements, modifiers, functions, etc (like 'for' loop) but i don't really know if i should use another module that i don't know about. I thought of regular expressions but i kind feel like that wouldn't be an efficient way of doing it Any help is appreciated, and i'm sure this will be of use to other people too. Thank you

  • Controlling the order of PicoContainer startup

    - by Trejkaz
    I have been tasked with doing some refactoring work on how we start up applications. Basically we have a bunch of console apps which were depending on the GUI application startup code, causing bogus dependencies which have kick-on effects for which libraries we need to ship, and which dependencies other modules need to declare. So I have written a simple startup framework where I basically just throw a bunch of Runnable objects into a list and then run them in order - and it works. But I was thinking - we already have PicoContainer in our project, so all these things that need to be run on startup could potentially be thrown into a PicoContainer, and if they implement Startable they will start... But in some cases we want to specify the ordering between them. For example, I don't want any other component writing to the log before we write a header into the log indicating that the application is starting up. I know I can introduce ordering by introducing injection dependencies, but this feels like a hack in this case - I would need to add the log header writer as a dependency for every other component which might write to the log, which isn't great at all. Nonetheless it seems like it would be nice to control the order of PicoContainer startup, so is there perhaps some other way? Alternatively I could just keep it simple and stick to my list of Runnable. It does, after all, work.

  • how to read http response soap headers from web service response in proxy class

    - by Fabricio
    I'm having some problems with one webservice that i'm working with. I generated a proxy class with wsdl.exe that comes with .net framework. But that webservice return a header that isnt not mapped by the wsdl. I must map the header sop because it contains some properties that i have to read and work with. how can i read the soap's header collection? Ex.: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header xmlns="http://xml.amadeus.com/ws/2009/01/WBS_Session-2.0.xsd"> <Session> <SessionId>545784545</SessionId> <SequenceNumber>1</SequenceNumber> <SecurityToken>asd7a87sda89sd45as4d5a4</SecurityToken> </Session> </soap:Header> <soap:Body> <TAM_Altea_Seguranca_AutenticarRS xmlns="http://xml.amadeus.com/2009/04/TAM/TAM_Altea_Seguranca_AutenticarRS_2.0"> <statusDoProcesso> <codigoDoStatus>P</codigoDoStatus> </statusDoProcesso> </TAM_Altea_Seguranca_AutenticarRS> </soap:Body> </soap:Envelope> I need to read the SOAP:HEADER - Session.

  • Complex derived attributes in Django models

    - by rabidpebble
    What I want to do is implement submission scoring for a site with users voting on the content, much like in e.g. reddit (see the 'hot' function in http://code.reddit.com/browser/sql/functions.sql). My submission model currently keeps track of up and down vote totals. Currently, when a user votes I create and save a related Vote object and then use F() expressions to update the Submission object's voting totals. The problem is that I want to update the score for the submission at the same time, but F() expressions are limited to only simple operations (it's missing support for log(), date_part(), sign() etc.) From my limited experience with Django I can see 4 options here: extend F() somehow (haven't looked at the code yet) to support the missing SQL functions; this is my preferred option and seems to fit within the Django framework the best define a scoring function (much like reddit's 'hot' function) in my database, and have Django use the value of that function for the value of the score field; as far as I can tell, #2 is not possible wrap my two step voting process in a suitably isolated transaction so that I can calculate the voting totals in Python and then update the Submission's voting totals without fear that another vote against the submission could be added/changed in the meantime; I'm hesitant to take this route because it seems overly complex - what is a "suitably isolated transaction" in this case anyway? use raw SQL; I would prefer to avoid this entirely -- what's the point of an ORM if I have to revert to SQL for such a common use case as this! (Note that this coming from somebody who loves sprocs, but is using Django for ease of development.) Before I embark on this mission to extend F() (which I'm not sure is even possible), am I about to reinvent the wheel? Is there a more standard way to do this? It seems like such a common use case and yet in an hour of searching I have yet to find a common solution...

  • Caching sitemaps in django

    - by michuk
    I implemented a simple sitemap class using django's default sitemap app. As it was taking a long time to execute, I added manual caching: class ShortReviewsSitemap(Sitemap): changefreq = "hourly" priority = 0.7 def items(self): # try to retrieve from cache result = get_cache(CACHE_SITEMAP_SHORT_REVIEWS, "sitemap_short_reviews") if result!=None: return result result = ShortReview.objects.all().order_by("-created_at") # store in cache set_cache(CACHE_SITEMAP_SHORT_REVIEWS, "sitemap_short_reviews", result) return result def lastmod(self, obj): return obj.updated_at The problem is that memcache allows only max 1MB object. This one was bigger that 1MB, so storing into cache failed: >7 SERVER_ERROR object too large for cache The problem is that django has an automated way of deciding when it should divide the sitemap file into smalled ones. According to the docs (http://docs.djangoproject.com/en/dev/ref/contrib/sitemaps/): You should create an index file if one of your sitemaps has more than 50,000 URLs. In this case, Django will automatically paginate the sitemap, and the index will reflect that. What do you think would be the best way to enable caching sitemaps? - Hacking into django sitemaps framework to restrict a single sitemap size to, let's say, 10,000 records seems like the best idea. Why was 50,000 chosen in the first place? Google advice? random number? - Or maybe there is a way to allow memcached store bigger files? - Or perhaps onces saved, the sitemaps should be made available as static files? This would mean that instead of caching with memcached I'd have to manually store the results in the filesystem and retrieve them from there next time when the sitemap is requested (perhaps cleaning the directory daily in a cron job). All those seem very low level and I'm wondering if an obvious solution exists...
