  • PHP (CodeIgniter) Pass Object Through Session

    - by FranticPedantic
    I am using PHP5 and CodeIgniter and I am trying to implement a single-sign on feature with facebook (although I don't think that facebook is relevant to the question). I am somewhat of a novice with PHP and definitely one with CodeIgniter, so if you think my approach is just completely off telling me that would be helpful too. So here is in short what I am doing: //Controller 1 $this->load->plugin("facebook"); $facebook = new Facebook(array ( 'appId' => $fbconfig['appid'], 'secret' => $fbconfig['secret'], 'cookie' => true, ) ); $fbsession = $facebook->getSession(); //works fine $this->session->set_userdata('facebook', serialize($facebook); Now I would like to grab that facebook object in a different controller. //Controller 2 $facebook = unserialize($this->session->userdata('facebook')); $fbsession = $facebook->getSession(); Produces the error: Call to undefined method getSession. So I look up more about serialization and think that maybe it just doesn't know what the facebook object's attributes are. So I add in a $this->load->plugin('facebook'); To controller 2 as well and I get a "Cannot redeclare class facebook." I am strongly suspecting that I am misunderstanding sessions here. Do I have to somehow tell PHP what kind of object it is? Thanks for the help.

  • Ruby Doesn't Recognize Alias Method

    - by Jesse J
    I'm trying to debug someone else's code and having trouble figuring out what's wrong. When I run rake, one of the errors I get is: 2) Error: test_math(TestRubyUnits): NoMethodError: undefined method `unit_sin' for CMath:Module /home/user/ruby-units/lib/ruby_units/math.rb:21:in `sin' This is the function that calls the method: assert_equal Math.sin(pi), Math.sin("180 deg".unit) And this is what the class looks like: module Math alias unit_sin sin def sin(n) Unit === n ? unit_sin(n.to('radian').scalar) : unit_sin(n) end alias unit_cos cos def cos(n) Unit === n ? unit_cos(n.to('radian').scalar) : unit_cos(n) end ... module_function :unit_sin module_function :sin module_function :unit_cos module_function :cos ... end (The ellipsis means "more of the same"). As far as I can see, this is valid Ruby code. Is there something I'm missing here that's causing the error, or could the error be coming from something else? Update: I'm wondering if the problem has to do with namespaces. This code is attempting to extend CMath, so perhaps the alias and/or module_function isn't actually getting into CMath, or something like that....

  • After rich:extendedDataTable sortby, other actions are not getting executed

    - by kksachin
    I have several tabs and one of the tabs uses rich:extendedDataTable. If sortBy is clicked in the page where table is used and if I navigate to another page, it looks for the bean of the old page and throws an error saying that sortyBy of the column is undefined. E.g. If I use sortBy on userId in tab1 (where the column must have sortBy="#{data.userId}") and then I click on tab2, it looks for the data.userId and throws an error. I am using Richfaces version 3.2.2SR1. Can anyone help me on this? Here is the complete trace: javax.el.PropertyNotFoundException: /amendapplication/historyDetails.xhtml @33,174 sortBy="#{data.statusChangeTime}": Property 'statusChangeTime' not found on type uk.gov.wales.rpd.domain.applicationmanagement.ApplicationAttributeEntity com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:73) org.richfaces.model.impl.expressive.ValueBindingExpression.evaluate(ValueBindingExpression.java:59) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapObject(ObjectWrapperFactory.java:189) org.richfaces.model.ModifiableModel$RowKeyWrapperFactory.wrapObject(ModifiableModel.java:57) org.richfaces.model.impl.expressive.ObjectWrapperFactory$2.convert(ObjectWrapperFactory.java:177) org.richfaces.model.impl.expressive.ObjectWrapperFactory.convertList(ObjectWrapperFactory.java:138) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapList(ObjectWrapperFactory.java:175) org.richfaces.model.ModifiableModel.sort(ModifiableModel.java:235) org.richfaces.model.ModifiableModel.modify(ModifiableModel.java:206) org.richfaces.component.UIExtendedDataTable.createDataModel(UIExtendedDataTable.java:310) org.ajax4jsf.component.UIDataAdaptor.getExtendedDataModel(UIDataAdaptor.java:621) org.ajax4jsf.component.UIDataAdaptor.setRowKey(UIDataAdaptor.java:339) org.ajax4jsf.component.UIDataAdaptor.iterate(UIDataAdaptor.java:1034) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1158) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1168) javax.faces.component.UIForm.processDecodes(UIForm.java:209) org.ajax4jsf.component.AjaxViewRoot$1.invokeContextCallback(AjaxViewRoot.java:392) org.ajax4jsf.component.AjaxViewRoot.processPhase(AjaxViewRoot.java:238) org.ajax4jsf.component.AjaxViewRoot.processDecodes(AjaxViewRoot.java:409) com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:78) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) javax.faces.webapp.FacesServlet.service(FacesServlet.java:265) org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:341) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:177) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:267) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:380) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

  • standard way to perform a clean shutdown with Boost.Asio

    - by Timothy003
    I'm writing a cross-platform server program in C++ using Boost.Asio. Following the HTTP Server example on this page, I'd like to handle a user termination request without using implementation-specific APIs. I've initially attempted to use the standard C signal library, but have been unable to find a design pattern suitable for Asio. The Windows example's design seems to resemble the signal library closest, but there's a race condition where the console ctrl handler could be called after the server object has been destroyed. I'm trying to avoid race conditions that cause undefined behavior as specified by the C++ standard. Is there a standard (correct) way to stop the server? So far: #include <csignal> #include <functional> #include <boost/asio.hpp> using std::signal; using boost::asio::io_service; extern "C" { static void handle_signal(int); } namespace { std::function<void ()> sighandler; } void handle_signal(int) { sighandler(); } int main() { io_service s; sighandler = std::bind(&io_service::stop, &s); auto res = signal(SIGINT, &handle_signal); // race condition? SIGINT raised before I could set ignore back if (res == SIG_IGN) signal(SIGINT, SIG_IGN); res = signal(SIGTERM, &handle_signal); // race condition? SIGTERM raised before I could set ignore back if (res == SIG_IGN) signal(SIGTERM, SIG_IGN); s.run(); // reset signals signal(SIGTERM, SIG_DFL); signal(SIGINT, SIG_DFL); // is it defined whether handle_signal can still be in execution at this // point? sighandler = nullptr; }

  • Why can't I build this Javascript object?

    - by Alex Mcp
    I have an object I'm trying to populate from another object (that is, iterate over a return object to produce an object with only selected values from the original). My code looks like this: var collect = {}; function getHistoricalData(username){ $.getJSON("http://url/" + username + ".json?params", function(data){ for (var i=0; i < data.length; i++) { console.log(i); collect = { i : {text : data[i].text}}; $("#wrap").append("<span>" + data[i].text + "</span><br />"); }; console.log(collect); }); } So I'm using Firebug for debugging, and here's what I know: The JSON object is intact console.log(i); is showing the numbers 1-20 as expected When I log the collect object at the end, it's structure is this: var collect = { i : {text : "the last iteration's text"}}; So the incrementer is "applying" to the data[i].text and returning the text value, but it's not doing what I expected, which is create a new member of the collect object; it's just overwriting collect.i 20 times and leaving me with the last value. Is there a different syntax I need to be using for assigning object members? I tried collect.i.text = and collect[i].text = and the error was that whatever I tried was undefined. I'd love to know what's going on here, so the more in-depth an explanation the better. Thanks!

  • JW Player playlist only loads randomly in IE, works fine in FF every time

    - by meow
    The playlist loads every time in FF but only the first time in IE (6-8), after that only randomly. If I alert the error that's thrown I get "TypeError: playerReady is undefined". My code looks good and obviously works since FF displays the playlist perfectly. I've got no idea how to solve this. Anyone? <script type='text/javascript'> var so = new SWFObject('/UI/Flash/player.swf', 'ply', '<%=FlashWidth %>', '<%=FlashHeight %>', '9', '#ffffff'), playlistURL = '<%=PlaylistURL %>', imageURL = '<%=GetBackgroundImageUrl() %>'; so.addParam('allowfullscreen', 'true'); so.addParam('allowscriptaccess', 'always'); if (playlistURL !== '') { so.addVariable('playlistfile', playlistURL); so.addVariable('playlist', 'none'); so.addVariable('enablejs', 'true'); } else { so.addVariable('file', '<%=FlashURL %>'); } if (imageURL.length > 0) { so.addVariable('image', imageURL); } so.write('preview<%=PlayerID %>'); </script>

  • Template operator linker error

    I have a linker error I've reduced to a simple example. The build output is: debug/main.o: In function main': C:\Users\Dani\Documents\Projects\Test1/main.cpp:5: undefined reference tolog& log::operator<< (char const (&) [6])' collect2: ld returned 1 exit status It looks like the linker ignores the definition in log.cpp. I also cant put the definition in log.h because I include the file alot of times and it complains about redefinitions. main.cpp: #include "log.h" int main() { log() << "hello"; return 0; } log.h: #ifndef LOG_H #define LOG_H class log { public: log(); template<typename T> log &operator <<(T &t); }; #endif // LOG_H log.cpp: #include "log.h" #include <iostream> log::log() { } template<typename T> log &log::operator <<(T &t) { std::cout << t << std::endl; return *this; }

  • Newb Question: passing objects in java?

    - by Adam Outler
    Hello, I am new at java. I am doing the following: Read from file, then put data into a variable. checkToken = lineToken.nextToken(); processlinetoken() } But then when I try to process it... public static void readFile(String fromFile) throws IOException { BufferedReader reader = new BufferedReader(new FileReader(fromFile)); String line = null; while ((line=reader.readLine()) != null ) { if (line.length() >= 2) { StringTokenizer lineToken = new StringTokenizer (line); checkToken = lineToken.nextToken(); processlinetoken() ......

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method nextToken() is undefined for the type String at testread.getEngineLoad(testread.java:243) at testread.readFile(testread.java:149) at testread.main(testread.java:119) so how do I get this to work? It seems to pass the variable, but nothing after the . works.

  • DATE_FORMAT in DQL symfon2

    I would like to use some MySQL functions such as DATE_FORMAT in my QueryBuilder.

  • Ajax Javascript method cannot be called

    - by blackmage
    I made this method to load javascript functions dynamically. It does include the .js file but when I call a method, the method says that it is undefinited. The following to .js files are ajax_object.js and user_manager.js . The alert outside the function is read and works but the alert inside does not. enter code here //ajax_object.js //Load a javascript library function loadJavascript( src, url ){ XMLHttpRequestObject=getXmlHttpRequestObject(); if( XMLHttpRequestObject){ XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 ){ if (XMLHttpRequestObject.status == 200 || XMLHttpRequestObject.status == 304) { includeJavaScript( src, url, XMLHttpRequestObject.responseText ); } } } } XMLHttpRequestObject.open('GET', url, true); XMLHttpRequestObject.send(null); }//end LoadJavaScript //Add Library to header function includeJavaScript(src, fileUrl, xmlObject) { if ( ( xmlObject != null ) && ( !document.getElementById( src ) ) ){ var documentHead = document.getElementsByTagName('HEAD').item(0); var includeScript = document.createElement( "script" ); includeScript.language = "javascript"; includeScript.type = "text/javascript"; //includeScript.id = src; includeScript.src=fileUrl.concat(src); includeScript.defer = true; includeScript.text = xmlObject; documentHead.appendChild( includeScript ); } } //user_manager.js //First alert is read alert("Outside User Manager"); function selectUserManagerModuleType(){ XMLHttpRequestObject=getXmlHttpRequestObject(); //This doesn't work //throws selectUserManagerModuleType undefined alert("Inside The User Manager"); }

  • How do set up jquery to exclude classes in a function?

    - by user1497158
    I essentially only understand how to read bits of javascript and make modifications. I am using grid-slider, a script I purchased, but the code writer is mia at the moment, so hopefully someone here can help me. Basically, it's a slider and there are options to have links open like normal or to have links open in a panel on the same page. I want some links to open in a panel and others to open in the parent window. It seems to me that all that would be required to do this would be to activate the panel display function (which I've done) and then set up an exclude function to exclude certain uls or lis with a specific class from the function. I've read about the .not selector, but I don't see how to make it applicable to this code: enter code hereelse { enter code here if (this._displayOverlay) { if ($item.find(">.content").size() > 0) { $item.data("type", "static"); } else { var contentType = this.getContentType($link); var url = $link.attr("href"); $item.data({type:contentType, url:(typeof url != "undefined") ? url : ""}); } $item.css("cursor", "pointer").bind("click", {elem:this, i:i}, this.openOverlay); } $link.data("text", $item.find(">div:first").html()); $img = $link.find(">img"); } Can anyone help based on looking at this? Here's a link to the demo of the code: http://codecanyon.net/item/jquery-grid-style-slider/full_screen_preview/1204040 Thank you.

  • Problem with Railscast #197 - Nested Model Form Part 2

    - by sscirrus
    I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

  • SOLVED: Lisp: macro calling a function works in interpreter, fails in compiler (SBCL + CMUCL)

    - by ttsiodras
    As suggested in a macro-related question I recently posted to SO, I coded a macro called "fast" via a call to a function (here is the standalone code in pastebin): (defun main () (progn (format t "~A~%" (+ 1 2 (* 3 4) (+ 5 (- 8 6)))) (format t "~A~%" (fast (+ 1 2 (* 3 4) (+ 5 (- 8 6))))))) This works in the REPL, under both SBCL and CMUCL: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (load "bug.cl") 22 22 $ Unfortunately, however, the code no longer compiles: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (compile-file "bug.cl") ... ; during macroexpansion of (FAST (+ 1 2 ...)). Use *BREAK-ON-SIGNALS* to ; intercept: ; ; The function COMMON-LISP-USER::CLONE is undefined. So it seems that by having my macro "fast" call functions ("clone","operation-p") at compile-time, I trigger issues in Lisp compilers (verified in both CMUCL and SBCL). Any ideas on what I am doing wrong and/or how to fix this?

  • Handle order dependence in loops

    - by Matt
    Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width; // Undefined! Or atleast not set yet.. } } Class B { public $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! EDIT: Ok just to clarify.. My main problem is that Class A relies on Class B, but class A is instantiated before class B, so therefore width has not yet been defined in class B. I am looking for a good way to make sure all the classes are loaded for everyone allowing the interdependencies to exist. For the future, please don't consider any syntax errors.. I just made up this example on the spot. Also assume that I have access to class B from class A after class B gets instantiated. I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler

  • Rails NoMethodError in loop when method exists

    - by Kevin Whitaker
    Good day all. I'm running into a bit of a problem getting a script running on my production environment, even though it works just fine on my dev box. I've verified that all the requisite gems and such are the same version. I should mention that the script is intended to be run with the script/runner command. Here is a super-condensed version of what I'm trying to do, centered around the part that's broken: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end markets = Market.find(all) markets.each do |market| deal = market.currentDeal puts deal.subject end Now convertToTimeZone is a method attached to the model. So, this code works just fine on my dev machine, as stated. However, attempting to run it on my production machine results in: undefined method `subject' for nil:NilClass (NoMethodError) If, however, I go into the console on the production box and do this: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end market = Market.find(1) deal = market.currentDeal puts deal.subject It returns the correct value, no problem. So what is going on? This is on rails v 2.3.5, on both machines. Thanks for any help

  • How to find/extract data from xml with jQuery

    - by darryl
    I'm trying to extract the StateLongName and StateShortName values from the xml below. I know there has to be a simple elegant way to do this with jQuery. <NewDataSet> <Table> <StateLongName>Alabama</StateLongName> <StateShortName>AL</StateShortName> </Table> <Table> <StateLongName>Alaska</StateLongName> <StateShortName>AK</StateShortName> </Table> ...elments removed for brevity </NewDataSet> Here's what I've tried. Load the xml from above into a Javascript variable name xml. Try #1 $(xml).find("TABLE").each(function() { var stateName = $(this).find("StateLongName").innerText; var stateCode = $(this).find("StateShortName").innerText; }); Try #1 doesn't find anything and never goes inside to load the stateName and stateCode variables. Try #2 $(xml).find("StateLongName").each(function() { var stateName = $(this).find("StateLongName").innerText; var stateCode = $(this).find("StateShortName").innerText; }); Try #2 does find matches, however the stateName and stateCode are left undefined. Try #3 $(xml).find("StateLongName").each(function() { var stateName = $($(xml).find('StateLongName').parent()[0].innerHTML)[1].data; var stateCode = $($(xml).find('StateLongName').parent()[0].innerHTML)[5].data; }); Try #3 works but there has to be a better way. Please enlighten me. Thanks for you time!

  • How to provide js-ctypes in a spidermonkey embedding?

    - by Triston J. Taylor
    Summary I have looked over the code the SpiderMonkey 'shell' application uses to create the ctypes JavaScript object, but I'm a less-than novice C programmer. Due to the varying levels of insanity emitted by modern build systems, I can't seem to track down the code or command that actually links a program with the desired functionality. method.madness This js-ctypes implementation by The Mozilla Devs is an awesome addition. Since its conception, scripting has been primarily used to exert control over more rigorous and robust applications. The advent of js-ctypes to the SpiderMonkey project, enables JavaScript to stand up and be counted as a full fledged object oriented rapid application development language flying high above 'the bar' set by various venerable application development languages such as Microsoft's VB6. Shall we begin? I built SpiderMonkey with this config: ./configure --enable-ctypes --with-system-nspr followed by successful execution of: make && make install The js shell works fine and a global ctypes javascript object was verified operational in that shell. Working with code taken from the first source listing at How to embed the JavaScript Engine -MDN, I made an attempt to instantiate the JavaScript ctypes object by inserting the following code at line 66: /* Populate the global object with the ctypes object. */ if (!JS_InitCTypesClass(cx, global)) return NULL; /* I compiled with: g++ $(./js-config --cflags --libs) hello.cpp -o hello It compiles with a few warnings: hello.cpp: In function ‘int main(int, const char**)’: hello.cpp:69:16: warning: converting to non-pointer type ‘int’ from NULL [-Wconversion-null] hello.cpp:80:20: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] hello.cpp:89:17: warning: NULL used in arithmetic [-Wpointer-arith] But when you run the application: ./hello: symbol lookup error: ./hello: undefined symbol: JS_InitCTypesClass Moreover JS_InitCTypesClass is declared extern in 'dist/include/jsapi.h', but the function resides in 'ctypes/CTypes.cpp' which includes its own header 'CTypes.h' and is compiled at some point by some command during 'make' to yeild './CTypes.o'. As I stated earlier, I am less than a novice with the C code, and I really have no idea what to do here. Please give or give direction to a generic example of making the js-ctypes object functional in an embedding.

  • Performance Difference between HttpContext user and Thread user

    - by atrueresistance
    I am wondering what the difference between HttpContext.Current.User.Identity.Name.ToString.ToLower and Thread.CurrentPrincipal.Identity.Name.ToString.ToLower. Both methods grab the username in my asp.net 3.5 web service. I decided to figure out if there was any difference in performance using a little program. Running from full Stop to Start Debugging in every run. Dim st As DateTime = DateAndTime.Now Try 'user = HttpContext.Current.User.Identity.Name.ToString.ToLower user = Thread.CurrentPrincipal.Identity.Name.ToString.ToLower Dim dif As TimeSpan = Now.Subtract(st) Dim break As String = "nothing" Catch ex As Exception user = "Undefined" End Try I set a breakpoint on break to read the value of dif. The results were the same for both methods. dif.Milliseconds 0 Integer dif.Ticks 0 Long Using a longer duration, loop 5,000 times results in these figures. Thread Method run 1 dif.Milliseconds 125 Integer dif.Ticks 1250000 Long run 2 dif.Milliseconds 0 Integer dif.Ticks 0 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long HttpContext Method run 1 dif.Milliseconds 15 Integer dif.Ticks 156250 Long run 2 dif.Milliseconds 156 Integer dif.Ticks 1562500 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long So I guess what is more prefered, or more compliant with webservice standards? If there is some type of a performance advantage, I can't really tell. Which one scales to larger environments easier?

  • How do I make a grouped select box grouped by a column for a given model in Formtastic for Rails?

    - by jklina
    In my Rails project I'm using Formtastic to manage my forms. I have a model, Tags, with a column, "group". The group column is just a simple hardcoded way to organize my tags. I will post my Tag model class so you can see how it's organized class Tag < ActiveRecord::Base class Group BRAND = 1 SEASON = 2 OCCASION = 3 CONDITION = 4 SUBCATEGORY = 5 end has_many :taggings, :dependent => :destroy has_many :plaggs, :through => :taggings has_many :monitorings, :as => :monitorizable validates_presence_of :name, :group validates_uniqueness_of :name, :case_sensitive => false def self.brands(options = {}) self.all({ :conditions => { :group => Group::BRAND } }.merge(options)) end def self.seasons(options = {}) self.all({ :conditions => { :group => Group::SEASON } }.merge(options)) end def self.occasions(options = {}) self.all({ :conditions => { :group => Group::OCCASION } }.merge(options)) end def self.conditions(options = {}) self.all({ :conditions => { :group => Group::CONDITION } }.merge(options)) end def self.subcategories(options = {}) self.all({ :conditions => { :group => Group::SUBCATEGORY } }.merge(options)) end def self.non_brands(options = {}) self.all({ :conditions => [ "`group` != ? AND `group` != ?", Tag::Group::SUBCATEGORY, Tag::Group::BRAND] }.merge(options)) end end My goal is to use Formtastic to provide a grouped multiselect box, grouped by the column, "group" with the tags that are returned from the non_brands method. I have tried the following: = f.input :tags, :required => false, :as => :select, :input_html => { :multiple => true }, :collection => tags, :selected => sel_tags, :group_by => :group, :prompt => false But I receive the following error: (undefined method `klass' for nil:NilClass) Any ideas where I'm going wrong? Thanks for looking :]
