• Help getting ActiveScaffold to work properly

  - by x3ro

  Hey there I was curious about the ActiveScaffold Rails plugin, but somehow I can't get it to work properly. I've followed the steps which are described on http://activescaffold.com/tutorials/ . The table and everything shows up and when I click on "Create new", the dialog pops up. However, when I fill out the form and click "Create", I just get "500 Internal server error". In the server log, it says "NameError (wrong constant name ###):", with ### being what I entered in the first form field. If I don't enter anything in the form, it says "NoMethodError (undefined method `new_record?' for #):"... So what am I doing wrong here? Thanks in advance for your help :)

• How to configure grails and shiro to mark cookies secure?

  - by j4y

  I'm using Grails 2.2.4 with the Shiro plugin (v1.1.4) and would like to mark the cookies as secure so the session information won't be sent over http. This is the attribute I want to set: securityManager.sessionManager.sessionIdCookie.secure = true The shiro source says to use the Grails bean property override mechanism, which is grails-app/conf/spring/resources.groovy How can I override just the one setting? // If the legacy 'security.shiro.filter.config' option is set, // use our custom INI-based filter... if (application.config.security.shiro.filter.config) { log.warn "security.shiro.filter.config option is deprecated. Use Grails' bean property override mechanism instead." 'filter-class'('org.apache.shiro.grails.LegacyShiroFilter') 'init-param' { 'param-name'('securityManagerBeanName') 'param-value'('shiroSecurityManager') }

• How important is caching for a site's speed with PHP?

  - by benhowdle89

  I've just made a user-content orientated website http://www.humanisms.co.uk Its done in PHP, MySQL and jQuery's AJAX, at the moment there is only a dozen or so submissions and already i can feel it lagging slightly when it goes to a new page (therefore running a new mysql query) Is it most important for me to try and optimise my mysql queries (by prepared statements) or is it worth in looking at CDN's (amazon s3) and caching (much like the WordPress plugin WP Super Cache) which works by serving static HTML files when there hasnt been new content submitted. Which route is the most beneficial, for me as a developer, to take, ie. where am i better off concentrating my efforts to speed up the site?

• jQuery - Slideshow with different sized images and text

  - by NicoJuicy

  I need some sort of slideshow, with text (something like moving boxes would be nice). I have tried several, but i'm always having problems with different sized images (the images can be for eg. 500px x 300px, but the next one can be 500px, 300px), this gives some problems with the pictures ... I hope you understand what i mean. It's very irritating to find a good jquery plugin that can deal with this problem... :( Can anyone find me a good working one or an alternative to jQuery?

• Web2py controllers with parameters?

  - by nickfranceschina

  I am building an app using Web2py framework... I don't want to have to use the request object to get all of the querystring parameters, instead I'd like to build my controller with named parameters and have the router unpack the querystring (or form data) dictionary into the named parameters and call my controller. so instead of a controller method of create_user(): where I would use the global request() object and look through the vars list... I would prefer instead to have create_user(first_name, last_name, email): like I see in other MVC platforms. is this possible in Web2py already? or is there a plugin for it? or do I need to add that myself?

• installing glassfish on ubuntu karmic using synaptics package manager

  - by Danny

  I'm trying to learn to use glassfish for the first time. My IDE is netbeans and I've installed the glassfish plugin for netbeans. I opened up synaptics package manager and typed in glassfish. My choices were imqv2 glassfish-activaton glassfish-mail glassfish-appserv glassfish-toplink-essentials glassfish-jmac-api glassfish-javaee I'm not sure what is in each package, or which package are needed. I can't seem to find anything that tells me anything descriptive about these packages. I've seen a lot of tutorials on how to install glassfish, but I'd prefer to use apt-get / synaptics to install glassfish so that syntactics can take care of updating.

• .NET Recaptcha https

  - by TygerKrash

  We've started using the ASP.NET recaptcha control and it works fine. but one of the requirements we have is that all outbound traffic goes over Https. I know that recaptcha supports https, but It's not clear how to configure (or even if it is configurable) when using the ASP.NET plugin option. has anyone got any experience of this? I'll expand a little on what I've found so far.... The Recaptcha package contains 3 public classes RecaptchaControl, RecaptchaValidator and RecaptchaResponse RecaptchaControl is an Asp.NET control, the recaptcha specific methods on there seem to be concerning themes/look and feel. An instance of the Validator has a RemoteIP field (which I presume would represent the verification server), but I can't a way of binding that to the control. RecaptchaResponse seems to more or less represent an enum with possible responses (valid/invalid/failed to connect).

• How do I mount my Android phone's filesystem on MacOS X? [closed]

  - by misbell

  I'm running a fully rooted Nexus One with Android 2.1. I can see /data/data in DDMS, both the plugin and the tool -- but when I attach my phone, I still can't see the main drive. All I can see is the SD card. Using OSX, when I use Disk Utility, I can see the machine then see the SD Card. Is the problem that none of the tools I am using, except DDMS and ADB shell, know how to read that main Android drive? It's the same format as the qemu img, right? Again -- my goal is to mount the phone's root filesystem on my MacOS X host when connected via USB.

• Tabcompletion and docview while editing rc.lua

  - by Berxue

  I saw that there is a lua plugin for eclipse and there is a docpage on the awesome main page api_doc and all the .lua files in /usr/share/awesome/lib. So I thought it must be possible to create a Library or Execution Environment so that one has tabcompletion and docview. So I tried making my own Execution Environment: wrote the standard .rockspec file downloaded the documentation made an ofline version of it and put it in docs/ folder ziped the files and folders in /usr/share/awesome/lib ziped all up tried it out ... and it failed. When I try to view a documentaion for a .lua file I get "Note: This element has no attached documentation." Questions: Am I totaly wrong in my doing (because I have the feeling I am)? Is there any way to edit the rc.lua with tabcompletion and docview?

• Play 2.0 RESTful request post-processing

  - by virtualeyes

  In regard to this question I am curious how one can do post-request REST processing a la (crude): def postProcessor[T](content: T) = { request match { case Accepts.Json() => asJson(content) case Accepts.Xml() => asXml(content) case _ => content } } overriding onRouteRequest in Global config does not appear to provide access to body of the response, so it would seem that Action composition is the way to go to intercept the response and do post-processing task(s). Question: is this a good idea, or is it better to do content-type casting directly within a controller (or other class) method where the type to cast is known? Currently I'm doing this kind of thing everywhere: toJson( i18n("account not found") ) toJson( Map('orderNum-> orderNum) ) while I'd like the toJson/toXml conversion to happen based on accepts header post-request.

• how to build GNU Classpath and JamVM

  - by michelemarcon

  I'm trying to build GNU Classpath 0.98 and JamVM 1.5.2. Following the JamVM readme, I did 'configure; make; make install' on the jamVM, and it worked. I then added jamvm and Sun javac to the path. Then with GNU Classpath I did this: ./configure --enable-jni --disable-gtk-peer --disable-gconf-peer --disable-plugin I got this error: The javac failed (see config.log) On the config.log, I see that javac can't find VMStackWalker (which is jamvm-specific) I added the jamvm classes to the CLASSPATH, then I got this error: The Java VM jamvm failed (see config.log) On the config.log, I see that jamvm cannot find java.lang.Class WTF?

• jQuery Validation using the class instead of the name value

  - by Matt

  Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

• Database storage for high sample rate data in web app

  - by Jim

  I've got multiple sensors feeding data to my web app. Each channel is 5 samples per second and the data gets uploaded bundled together in 1 minute json messages (containing 300 samples). The data will be graphed using flot at multiple zoom levels from 1 day to 1 minute. I'm using Amazon SimpleDB and I'm currently storing the data in the 1 minute chunks that I receive it in. This works well for high zoom levels, but for full days there will be simply be too many rows to retrieve. The idea I've currently got is that every hour I can crawl through the data and collect together 300 samples for the last hour and store them in an hour Domain (table if you like). Does this sound like a reasonable solution? How have others implemented the same sort of systems?

• How can I tell when changes to jquery html() have finished ?

  - by mike_t2e

  I'm using jQuery to change the HTML of a tag, and the new HTML can be a very long string. $("#divToChange").html(newHTML); I then want to select elements created in the new HTML, but if I put the code immediately following the above line it seems to create a race condition with a long string where the changes that html() is making may not necessarily be finished rendering. In that case, trying to select the new elements won't always work. What I want to know is, is there an event fired or some other way of being notified when changes to html() have finished rendering ? I came across the jQuery watch plugin, which works alright as workaround but it's not ideal. Is there a better way ?

• Animating shorthand CSS properties with jQuery

  - by Giulio Piancastelli

  Chapter 3 of jQuery Novice to Ninja starts with a section about animating CSS properties, and its first example suggests the following code should expand padding and add a couple of borders to every paragraph in a page: $('document').ready(function() { $('p').animate({ padding: '20px', borderBottom: '3px solid #8f8f8f', borderRight: '3px solid #bfbfbf' }, 2000); }); However, while the code indeed works with the jQuery 1.4 library included in the downloadable examples archive for the book, it only animates padding when used alongside jQuery 1.6, forgetting the shorthand CSS properties for border-bottom and border-right altogether. What happened in the transition between 1.4 and 1.6, causing the removal of this functionality? Has it been placed in some plugin? Is it possible to run this code as it's written and get back the border animation? If not, how would you animate border properties using jQuery 1.6?

• jQuery autocomplete: how to split the string result?

  - by Matt

  I have the following situation with an autocomplete plugin on an .aspx page. It is working fine. The result from the autocomplete search yields a product id and a product description is concatenated with it (i.e. 2099 -- A Product). I know that I need to use split() with this but where do I put it? I'm still rather new to jQuery and javascript. $(document).ready(function() { $('.divAutoComplete').autocomplete("LookupCodes.aspx?type=FC", { mustMatch: true }); });

• Help porting a bit of Prototype JavaScript to jQuery

  - by ewall

  I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!

• Good way to "wrap" jars for OSGi with Maven

  - by javamonkey79

  I was looking at the PAX tools on OPS4J for example: this one and I thought I'd found a nice way to: Specify an artifact Create an assembled jar (jar that contains all dependencies) from that jar and it's transitive dependencies Wrap it with BND to create an OSGi bundle It turns out, that I was wrong - it doesn't appear that the PAX stuff does this. (RTFM, right? :) ) But this got me wondering: is there something out there that does what I'm asking? I've thought maybe I could do this by creating a simple POM and using the maven-bundle-plugin but this seems like it might be a bit cumbersome for what I'm asking. NOTE: I get that embedding and assembling jar's is not really "the OSGi way" - so I wouldn't do this unless I really felt it useful. For example - Spring. Thanks in advance.

• jquery cookie - hoursToLive

  - by mathiregister

  Hi guys, i'm using the jquery cookie plugin. Everything works fine except the fact that I have no idea how to set an expiration-time for the cookie? $.cookie('opt_visible', 'true'); the jquery-cookie documentation says: hoursToLive (DEPRECATED for expiresAt) NUMBER For how many hours should the cookie be valid? (Passing 0 means to delete the cookie at the end of the browser session--this is default. Negative values will delete the cookie, but you should use the del() method instead.) That's exactly what I'd like to have. The cookie should be available as long as i'm browsing the site. As soon as i close the window or browsertab, the cookie should be deleted. How can i implement this hoursToLive thingy to my mentioned line above? Thank you

• zend_acl: Adding extra resources dynamically and getting a param predispatch

  - by Timmeh

  First sorry about the woffle as I'm not sure how best to describe this. Basically I am not sure how I can get param in the bootstrap before the controller is loaded, but here is the long winded version... I have got an acl class storing all my default resources in. All my page/post content is a database and I want the admin the ability to choose who which role the page would become available. I know it is possible just to loop through the database table and add them all in at once, but I am concerned that this is a drain on resources. I have it working whereby my access check plugin can call a dynamic permission function, but I need to get the parameter of the current page ID and it's permission to set it before the controller is loaded. Does that make sense or am I worry over nothing and I should just get the resources of all the pages at once? thanks in advance for reading my garble!!

• Function testing on Netbeans 6.8

  - by ron

  While not a torrent, but some articles can be found on the net about function testing (particularly http://blogs.sun.com/geertjan/entry/gui_testing_on_the_netbeans). However the tools mentioned by them do not seem to be maintained, or don't have a plugin working with the most recent version of Netbeans (6.8). Do you have any function test setup for GUI? What is your level of integration into the development process (IDE integration, ant, etc). Additional candy is that Netbeans is not only the IDE, but the GUI app is also developed for Netbeans 6.8 Platform (so I'm mainly interested in GUI testing NB-platform apps, but tips for any Swing apps in general would be a help too).

• Mobile Safari Youtube opened via javascript

  - by Squeegy

  We have a youtube player embedded in a plage in Mobile Safari and it works great. But we need to be able to launch the youtube player by a means other than user tapping the video itself, for various reasons. So I am trying to figure out what event to trigger in javascript to make it happen with no luck. None of the following appear to work. var vid = document.getElementById('vid'); vid.click(); vid.onclick(); vid.ontouchend(); vid.ontouchstart(); vid.focus(); I tried to find an event handler added to the embedded object with this snippet, but didn't find anything. for (var key in vid) { if (typeof vid[key] == 'function') console.log(key +': '+ vid[key]); } Is this just so wrapped up in a custom plugin there is no way?

• Dynamic instant theming a la My Yahoo / iGoogle

  - by Alex Neth

  I can think of lots of ways to do this on my own, but I was hoping to find some sort of best practice and have been having trouble finding other's experiences. I want to create easily themed HTML and provide a real-time selector for the user to experiment with themes. I want to do something like the "Change Appearance" tab at http://my.yahoo.com . I'll be using jQuery. jQuery has a "theming" system, but it seems very much focused on jQuery widgets as opposed to the whole site, and also doesn't appear to address the real-time selection aspect (the jQuery page has this functionality, but I don't think it's part of the library.) Maybe there is a jQuery plugin that already does this? Or some sort of css/jQuery framework?

• How to write a custom (odd) authentication plugins for Wordpress, Joomla and MediaWiki

  - by Bart van Heukelom

  On our network (a group of related websites - not a LAN) we have a common authentication system which works like this: On a network site ("consumer") the user clicks on a login link This redirects the user to a login page on our auth system ("RAS"). Upon successful login the user is directed back to the consumer site. Extra data is passed in the query string. This extra data does not include any information about the user yet. The consumer site's backend contacts RAS to get the information about the logged in user. So as you can see, the consumer site knows nothing about the authentication method. It doesn't know if it's by username/password, fingerprint, smartcard, or winning a game of poker. This is the main problem I'm encountering when trying to find out how I could write custom authentication plugins for these packages, acting as consumer sites: Wordpress Joomla MediaWiki For example Joomla offers a pretty simple auth plugin system, but it depends on a username/password entered on the Joomla site. Any hints on where to start?
