  • Form is creating already loaded attributes in addition to new attributes, how do I ignore the first?

    - by looloobs
    In my application you: Have an admin user that signs on and that user has a role (separate model), then I use the declarative_authorization plugin to give access to certain areas. That admin user can also register new users in the system, when they do this (using Authlogic) they fill out a nested form that includes that new users' role. So what is happening is the role of the admin user is being loaded by the declarative_authorization and then the nested form using the has_many_nested_attributes is loading that existing role as well as the new role for the new user (users can have many roles). Is there some way I can tell the new User being created to ignore the role assigned to the current_user and only create the role in the form for the new user? I have looked through a lot of different things, but it seems to get more complicated that these are nested attributes. Thanks in advance.

  • How to get at ResourceDictionary style when it is loaded from external xap and assemblies are MEF-fe

    - by user158503
    I've got the following setup: The main application loads a XAP with an IPlugin implementation. The Plugin contains a 'DisplayPanel' that contains a referenced Control with other controls. The DisplayPanel here is simply a container control to show referenced Control. This referenced Control, from an assembly, uses a Style from a ResourceDictionary xaml in this assembly. At least that's what I want to have. The problem is that the referenced Control throws an error: Cannot find a Resource with the Name/Key PlayerPanelGrad [Line: 1500 Position: 127] I've tried to get at the style by referencing the ResourceDictionary through a Merged Resource dictionary reference: <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="TableControls;component/ControlsStyle.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> But that doesn't work. How would you approch this?

  • iPhone c++ development / compiler on a non-Mac PC? (Windows? Linux?)

    - by Ehrann Mehdan
    According to the (in)famous iPhone Developer Program License Agreement change 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). So it is allowed to develop iPhone apps using C++ My questions Is there a compiler / IDE for developing iPhone apps using C++? Is that compiler / IDE available on non Mac environments? (Windows? Linux?) If not, why? I mean an eclipse C++ plugin for iPhone development will be quite popular, or is there already any serious attempt to do that?

  • jquery multiple select x rails edit action

    - by VP
    Hi, i'm using the JQUERY multiselectable plugin. Because it's get one select box and transform it in two, where you can move one selected option to another select box. The problem is that i'm facing some problems with the edit action. When i load the form, the selected values (that are saved in my model) are not being populated in the "selected" select box. There is anybody with a good idea about how to "automatically" move the selected values in my database from the "available to be selected" to "selected" options? For now i'm doing something like <%= select "product", :option_ids, options_for_select(Option.all.map { |opt| [opt.description, opt.id]}), {},{:multiple=> true,:class=>'multiselect'} %> Here i can see already the problem. I could just use as options_for_select just all options - the options that are already choosed in my model. The problem is how to update the select box with this information?

  • Building a code search engine for java code in git repositories

    - by zero1
    I'm trying to build a Java code search engine. Apart from just searching for keywords, I would also like cross-referencing between classes to work. It should work the way eclipse's referencing works - click on anything to open the definition. Bonus would be if something like search-all-usages-of-foo works. I'm thinking of using Apache Solr to index the files and build the basic search. But I'm not sure how I'd do the crossreferencing part since Solr doesn't understand Java code. Any suggestions on what I could use here? EDIT: I mainly want to index a lot of java git repositories.

  • Chain dynamically created dropdowns with JQuery

    - by ricardocasares
    I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

  • How can I use the Spark library in my ActionScript project?

    - by bluenote
    I'm using Flare to develop a visualization. Being familiar to Java, Javascript and Eclipse it wasn't a big deal to familiarize myself to developing with Actionscript and Adobe FlashBuilder. I actually found that the learning curve is very flat. However, being new to Actionscript, I can't figure out how to use the Spark libraries that are part of Flex. I tried to add the libraries to the build path, with no success. I guess I'm confused about how Flash, Flex, Actionscript, Spark and Flare work together, even after reading the helpful answers on this question Does anybody know which part of the puzzle I'm missing? Thanks.

  • Seam app with JBoss 'minimal' Config?

    - by Shadowman
    I'd like to improve the performance of my Seam apps and JBoss appserver, particularly by removing things that aren't necessary in the standard configuration. Ideally, I'd like to be able to run it using the "minimal" profile. Can anyone give me any guidance as to what is needed to run a Seam app using "minimal"? Here are the kind of things my app requires: JPA, using Hibernate with a PostgreSQL backend EJB3 JSF (RichFaces/Facelets) E-mail, eventually, although not required at this particular moment I'll be developing my app using JBoss Tools on Eclipse, so I would also need anything that is required by the tools for development and deployment. I've found that the default configuration just has too many additional components and features installed by default, and that greatly affects performance when I'm trying to develop. Any help you can give would be great! Thanks!

  • Jquery Ajaxform with input type=file and multifile

    - by crunchingnumbers
    Im using ajax form with multifile. However ajaxform just seems to quietly die and does not do anything if using multifile. Multifile is just a jquery plugin that builds a list of input type=file so that you can upload multiple files at once, before which you can add/delete your file upload list. I've looked at multifile and made one change to ensure that it generated a unique name as well as id which it didn't do before and i've checked the form elements multifile is building which all appear to be correct. From looking at ajaxform, it seems that it shoulld just generate the iframe as normal and post the multiple input type=file but it does nothing. Has anyone else experienced problems with multiple input type=file uploads

  • What benefits can Java developer have moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse there, so there will be no big difference. Guys, who use Java on *NIX, could you please give me a real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • In Vim, what is the best way to select, delete, or comment out large portions of multi-screen text?

    - by Edward Tanguay
    Selecting a large amount of text that extends over many screens in an IDE like Eclipse is fairly easy since you can use the mouse, but what is the best way to e.g. select and delete multiscreen blocks of text or write e.g. three large methods out to another file and then delete them for testing purposes in Vim when using it via putty/ssh where you cannot use the mouse? I can easily yank-to-the-end-of-line or yank-to-the-end-of-code-block but if the text extends over many screens, or has lots of blank lines in it, I feel like my hands are tied in Vim. Any solutions? And a related question: is there a way to somehow select 40 lines, and then comment them all out (with "#" or "//"), as is common in most IDEs?

  • Why is display:inline killing IE 8.0 performance?

    - by monstermensch
    I have an image gallery based on this jQuery plugin: http://jqueryfordesigners.com/demo/slider-gallery.html This works really well in Firefox, Chrome and even IE 7.0, but when I try it with more than 50 images in IE 8.0 the performance is incredible slow. Just hovering over the thumbnail brings the CPU load to 100%. At first I thought it's a Javascript problem, so I used the IE profiler, but the results were normal. Next I checked the CSS and finally found the cause: .sliderGallery UL LI { display: inline; } This gets the thumbnails to align horizontally. If I chance it to display:block, performance is fine and the scroller is still working but obviously it looks funny, because the thumbs are aligned vertically. My questions: Why does IE 8 have this problem with many display:inline elements What can I do to solve it I'll gladly provide more information if necessary.

  • View returned file from Webservice method

    - by gafda
    I already have a method in my webservice that returns a byte[] containing only the bytes of the file downloading. The invocation is something like: http://www.mysite.com/myWebservice.asmx with: string fileId = "123"; bytes[] fileContent = myWebservice.Download(fileId); What I wanted to do is be able to invoke this method or other (to be made) on a aspx webpage and be able to open a browser window containing the real content of the file. i.e. Most files are TXT and PDF. (Assuming the client has the PDF plugin that alows him\her to view PDF's on the browser.)

  • Combining 2 PHP frameworks that both implement __() internationalization function

    - by mclin
    Never had a question I couldn't google until now, and it may be a doozy: I have a PHP site that combines Wordpress with Kohana - Wordpress for the blog, and Kohana for the custom functionality. This is done using a Wordpress plugin that stitches them together. This works great except they both define a __() internationalization function, with different arguments etc. so once wordpress has overridden kohana's __(), if kohana calls __() it explodes. I'm not that familiar with PHP so this might be naive, but shouldn't this stuff be namespaced? Is there anyway other than changing the source of one or the other framework to allow them to call their own respective __()?

  • Pylons and Pisa (xhtml2pdf): blank page in IE

    - by Utaal
    I'm using pylons to serve a dynamically generated pdf document for reporting: my approach works in firefox & chrome (it displays the pdf inline if the plugin is available or otherwise downloads it) but IE (7 & 8) only show a blank page and doesn't prompt for download. IE correctly shows PDFs generated by other websites, though. Don't know if it matters but the page is accessed through HTTPS. My controller does the following: renders the source page through mako converts the html to pdf using pisa adds these headers to the response: Content-type: application/pdf and Content-disposition: inline; filename=file.pdf Do you have any suggestion? I seem to be stuck and cannot think of anything else to try.

  • How can I create a class diagram with NetBeans' 6.8 UML module?

    - by Karussell
    It seems to me the UML module of NetBeans is a bit too much hidden. In NetBeans 6.5 it was very easy to create an UML diagram. No plugin installation necessary or sth. like. Read my post where I found a zip file to install the UML module. And now, after this procedure, I got the UML module back, but it seems to me that I cannot create class diagram with it. Do you know how I can do this with NetBeans 6.8? Update1: There seems to be no support Update2: Nevertheless somebody seems to got it working.

  • Create a callback function within a custom jQuery function

    - by Thomas
    I'm not sure how to approach this as I am fairly new to jQuery. I'm wanting to create a callback function within a custom function. Here's my example: function doSomething() { var output = 'output here'; // Do something here // This is where I want to create the callback function and pass output as a parameter } I want the callback function to be accessible by any number of scripts (e.g. more than one script can access this callback). This function (doSomething) is not part of a plugin but rather part of another callback function itself. I've also created a var within the function and want to pass that through the callback function as well. How can I do this?

    I'm trying to develop a Magento plugin which involves using coupons. Apparently after looking around I found I found a source that mentions use of a 'salesrule' table for coupons. However when I looked at my database i couldn't find it. However I did find 3 tables that had mention 'coupon' called 'coupon_aggregated', 'coupon_aggregated_order', and 'coupon_aggregated_updated'. I just wanted to know what is the difference between the 3 tables so I can start using them? I am on the latest version of Magento. Thanks guys in advance.

  • Navigation properties not set when using ADO.NET Mocking Context Generator

    - by olenak
    I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!

  • Build Pipelining and Continuous Integration with Maven and Hudson

    - by Brandon
    Currently the my team is considering splitting our single CI build process into a more streamlined multi-stage process to speed up basic build feedback and isolate different ci concerns. The idea we had was to have each stage exist in Hudson as a different build with the correct maven goal or maven plugin execution, then chain them together using the post-build hooks of Hudson. However to my knowledge, Maven as a build tool mandates that any lifecycle phase which is performed automatically builds every preceding lifecycle phase. This presents a number of problems the most significant of which is that maven is recreating the build resources with each distinct call and not using those of the previous stage. This not only breaks the consistency of the build lifecycle but has much more unnecessary processing overhead. Is there a way to accomplish pipelining with CI using Maven? Assuming there is, is there a way to let Hudson know to use those resources built from the previous stage in the next one?

  • setting java classpath for Libre Office Base in Fedora 16

    - by foampile
    using Fedora 16 OS. i want to use Libre Office Base to connect to MySQL. when i set up the JDBC connection, it asks me for the driver, however, it cannot be loaded (because it doesn't see it in the classpath). does anybody know how to set the classpath for Libre Office? is there like a config util tool for that? e.g. my driver is [B]com.mysql.jdbc.Driver [/B]situated in[B] /usr/share/java/mysql-connector-java-5.1.17.jar[/B]. it works fine when i connect from other JDBC clients, like straight Java or Eclipse Quantum plugin. the problem is that Libre Office does not ask me for the (class)path of where it can find the driver and i do not know where and how to set it so that it becomes visible. thanks
