  • How to direct link to an attribute set?

    - by monocat
    I have created attributes; “Shop by Type” and “Shop by Color”. They work great within the layered navigation and extended search. I’ve designed graphics and placed them in the home page and would like to link to the respective attribute’s assigned products. Been searching the webs, but so far have been unsuccessful. If there’s no direct possible way, the next method would be creating cms pages and linking to it directly. How can I display products that are assigned to a specific attribute? Specifically “Multiple Select” types. I know you guys prefer at least some attempts, but as mentioned, been playing with it with no luck. I would appreciate some kind of starting point. Happy Holidays! Edit: I was able to put together this code that lists all the products assigned to said category id. Tried to filter it down where it only displays products that have an assigned same attribute with no luck yet. Any ideas? <?php $cat_id = 123; // category id $category = Mage::getModel('catalog/category')->load($cat_id); $_products = $category->getProductCollection() ->addAttributeToSelect('shop_by_color'); if (($this->getProductCollection()) && $_products->getSize()): ?> By the way, $cat_id is a sub category of root. Is there an easier way to point to it instead of using direct id number?

  • iPhone or Android apps that use SMS based authentication?

    - by JSW
    What are some iPhone or Android applications that use SMS as their primary means of user authentication? I'm interested to see such apps in action. SMS-auth seems like a natural approach that is well-situated to mobile contexts. The basic workflow is: to sign up, a user provides a phone number; the app calls a backend webservice which generates a signed URL and sends it to the phone number via an SMS gateway; the user receives the SMS, clicks the link, and is thus verified and logged in. This results in a very strong user identity that is difficult to spoof yet fairly easy. It can be paired with a username or additional account attributes as needed for the product requirements. Despite the advantages, this does not seem to be in much use - hence my question. My initial assumption is that this is because products and users are wary of asking for / providing phone numbers, which users consider sensitive information. That said, I hope this becomes an increasingly more commonplace approach.

  • Please help with IFrame callback

    - by Code Sherpa
    Hi - thanks for clicking. I am trying to get status feedback using an IFrame for file uploads. I am not trying to get progress or percentages - just when a file is done uploading and if it was a success or failure. THE PROBLEM is that I can't seem to get the server response to appear on the client. I have to following design: I have an iframe on my page: <iframe id="target_frame" src="" style="border:0px; width:0px; height:0px"></iframe> The form tag points to it: <form enctype="multipart/form-data" id="fileUploadForm" name="fileUploadForm" action="picupload.aspx" method="post" target="target_frame"> And the submit button starts a file upload via the iframe: <input id="submit" type="submit" value="upload" /> In the picupload.aspx.cs file, I have a method that returns dynamic data. I then send it to the client: message = data; Response.Write(String.Format("<script language='javascript' type='text/javascript'>window.parent.handleResponse('{0}');</script>", message)); On the client, I have a response handler: function handleResponse(msg) { document.getElementById('statusDiv').innerHTML = msg; } My intent is to see the msg value change for each uploaded file but I never see anything appear in statusDiv, let alone dynamically changing messages. Can somebody please help??

  • Automatically creating DynaActionForms in Mockrunner via struts-config.xml

    - by T Reddy
    I'm switching from MockStrutsTestCase to Mockrunner and I'm finding that having to manually re-create all of my DynaActionForms in Mockrunner is a pain...there has to be an easier way?! Can somebody offer a tip to simplify this process? For instance, this form bean definition in struts-config.xml: <form-bean name="myForm" type="org.apache.struts.action.DynaActionForm"> <form-property name="property" type="java.lang.String"/> </form-bean> results in this code in Mockrunner: //define form config FormBeanConfig config = new FormBeanConfig(); config.setName("myForm"); config.setType(DynaActionForm.class.getName()); FormPropertyConfig property = new FormPropertyConfig(); property.setName("property"); property.setType("java.lang.String"); config.addFormPropertyConfig(property); //create mockrunner objects ActionMockObjectFactory factory = new ActionMockObjectFactory(); ActionTestModule module = new ActionTestModule(factory); DynaActionForm form = module.createDynaActionForm(config); Now imagine that I have dozens of DynaActionForms with dozens of attributes...that stinks!

  • jQuery .load from another page that contains Javascript

    - by Dave
    I've been using jQuery .load() to load content into a div. The content being .loaded occasionally has a document.ready() function which is called, and works, correctly (i.e. the ready() function is called). However, when I use an element ID in the .load(), such as: .load ("test.php #content"), the Javascript is no longer executed even if I put the script tag inside of the element that is being loaded. Does anyone have a solution to this other than to not use the element ID in the .load()? Thanks in advance. Here is the dynamic content (loadDialogTest.php): <div id="test"> <div> Hello, World! </div> <script type="text/javascript"> $(document).ready (function () { alert ("ready"); }); </script> </div> and here is the page (where the element ID is NOT specified) that loads it (shortened as much as possible while maintaining the form: <head> <script type="text/javascript"> $(document).ready (function () { $("#openDialog").click (function () { $("<div></div>") .load ("loadDialogTest.php") .appendTo ($("#containingDiv")) .dialog ({ autoOpen: 'false', title: 'Test This!', close: function () { $(this).dialog ('destroy').remove (); } }); }); }); </script> </head> <body> <a href="#" id="openDialog">Open it</a> <div id="containingDiv"> </div> </body> If I put #test after the .php file as the div to load, the jQuery ready() function is no longer called.

  • Use string to store statement (or part of a statement), and then add it to the code

    - by Dean
    I use multidimensional arrays to store product attributes (well Virtuemart does, to be precise). When I tried to echo the sub-arrays value, if the sub-array did not exist PHP threw: Fatal error: Cannot use string offset as an array To get around this, I attempted to create a function to check on every array level if it is an actual array, and if it is empty (when trying on the whole thing at once such as: is_array($array['level1']['level2']['level3']), I got the same error if level1 or level2 are not actual arrays). This is the function ($array contains the array to check, $array_levels is an array containing the names of the sub-arrays, in the order they should apper): function check_md_array($array,$array_levels){ if(is_array($array)){ $dimension = null; //This will store the dimensions string foreach($array_levels as $level){ $dimension .= "['" . $level . "']"; //Add the current dimension to the dimensions string if(!is_array($array/* THE CONTENT OF $dimension SHOULD BE INSERTED HERE*/)){ return false; } } return true; } } How can I take the string contained in $dimensions, and insert it into the code, to be part of the statement?

  • How to specify multiple values in where with AR query interface in rails3

    - by wkhatch
    Per section 2.2 of rails guide on Active Record query interface here: which seems to indicate that I can pass a string specifying the condition(s), then an array of values that should be substituted at some point while the arel is being built. So I've got a statement that generates my conditions string, which can be a varying number of attributes chained together with either AND or OR between them, and I pass in an array as the second arg to the where method, and I get: ActiveRecord::PreparedStatementInvalid: wrong number of bind variables (1 for 5) which leads me to believe I'm doing this incorrectly. However, I'm not finding anything on how to do it correctly. To restate the problem another way, I need to pass in a string to the where method such as "table.attribute = ? AND table.attribute1 = ? OR table.attribute1 = ?" with an unknown number of these conditions anded or ored together, and then pass something, what I thought would be an array as the second argument that would be used to substitute the values in the first argument conditions string. Is this the correct approach, or, I'm just missing some other huge concept somewhere and I'm coming at this all wrong? I'd think that somehow, this has to be possible, short of just generating a raw sql string.

  • what exactly is this.id ?

    - by kwokwai
    Hi all, I was doing some dynamic effect on DIV using JQuery when I found that the returned value of this.id varied from function to function. I got two sets of simple parent-child DIV tags like this: <DIV ID="row"> <DIV ID="c1"> <Input type="radio" name="testing" id="testing" VALUE="1">testing1 </DIV> </DIV> <DIV ID="row"> <DIV ID="c2"> <Input type="radio" name="testing" id="testing" VALUE="2">testing2 </DIV> </DIV> Code 1. $('#row DIV').mouseover(function(){ radio_btns.each(function() { $('#row DIV).addClass('testing'); // worked }); }); Code 2. $('#row DIV').mouseover(function(){ var childDivID = this.id; radio_btns.each(function() { $('#'+childDivID).parent('DIV').addClass('testing'); // didn't work }); }); I don't understand why only the first code couldn work and highlighted all the "row" DIV, but the first code failed to do so?

  • How do you Bind to a ComboBox in a DataTemplate?

    - by discwiz
    I have a listbox that is bound to an observable collection of Audio (custom class). The Audio class has two properties, DisplayText (string) and a property called TarpIds (Observable Collection of Integer). I need to allow the user to change the TarpID in the combo box for each list item displayed and catch the selection change. I created a DataTemplate that styles the DisplayText property from the Audio object and adds a ComboBox to display the available TarpIDs for this audio (These are dynamic and unique to each Audio). The DisplayText works great, but I can not get the TarpIDs to display in the ComboBox. Here is what I have so far and thanks for any help. FYI I set the ItemSource at run time that binds the ListUploadAudio to the Observable Collection of Audio. <Border BorderBrush="Red" Background="WhiteSmoke" CornerRadius="8"> <Border.Resources> <DataTemplate x:Key="UploadLayout" DataType="Audio"> <StackPanel Orientation="Vertical"> <TextBlock Text="{Binding Path=DisplayText}" FontWeight="Bold" Foreground="Blue"> </TextBlock> <ComboBox x:Name="ListBoxTarpIDs" ItemsSource="{Binding Path=TarpIds}"> </ComboBox> </StackPanel> </DataTemplate> </Border.Resources> <ListBox x:Name="ListUploadAudio" BorderBrush="Transparent" Background="Transparent" Width="230" Margin="10" Height="200" IsSynchronizedWithCurrentItem="True" SelectionMode="Multiple" ItemTemplate="{DynamicResource UploadLayout}"> </ListBox> </Border>

  • Static libraries in version-cross-compiled program

    - by Brian Postow
    I have a unix command line app (with big nasty makefile) that I'm trying to run on a mac. I am compiling it on a 10.6 system, with all of the appropriate libraries of course. The deployment environment is a 10.5 system, with no extra libraries. I compiled without -dynamic, and it appears to have static libraries, correctly. When I run it on the 10.6 system, it works. However, when I run it on the 10.5 system, I get: dyld: unknown required load command 0x80000022 I got this same error when I compiled things for the 10.6 system using the 10.5 xcode, so it looks like a version mis-match type problem. However, I used gcc-4.0, and $CFLAGS = -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 so it SHOULD be set up for 10.5... any ideas? thanks Editing an ancient question: I have the exact same problem on a different computer. This time I am at 10.5.8, fully update, the same executable works on 10.6 still. Has anyone had any luck with this in the months since I asked this?

  • nth-of-type only working for 1 and 2

    - by Owen O'Neill
    I have a styling problem, I am using WordPress and want to do have the first two classes completely different to the others. My ideal situation is to have: .si-biplace:nth-of-type(3) { float:left; margin:20px 0px 0px 0px; } .si-image:nth-of-type(3) { float:left; margin:20px 0px 0px 0px; border:0px; } .si-title:nth-of-type(3) { width:100px; height:20px; margin:0px; font-size:7px; color:#FFFFFF; font-weight:bold; } They seem to work fine when it is: .si-biplace { float:left; margin:-10px 0px 0px 0px; } .si-biplace:nth-of-type(2) { float:left; margin:-10px 0px 0px 15px; } Is there a reason why it will not work with nth-of-type(3) but will with nth of type 2? I basically want different attributes for every next time the div is used but cannot have separate div classes as it runs through a php array.

  • winUserControl in VS2010 - properties are not visible in designer

    - by mj82
    I have a problem with (I suppose) my Visual Studio 2010 Express environment: when I design my own UserControl, in Properties grid I can't see public properties of that control. They are however visible in the project, that reference this control. As it's Express Edition, I create new empty project, then add new UserControl to it. Then, for a test, I put following code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms; namespace Project1 { public partial class UserControl1 : UserControl { private int myNumber; [Browsable(true)] public int MyNumber { get { return myNumber; } set { myNumber = value; } } public UserControl1() { InitializeComponent(); } } } In VS 2008, as I remember, that should be enogh to show MyNumber property in Properties grid, even without [Browsable(true)] attribute. In VS 2010 however, when I double click UserControl1.cs in Solution Explorer and look in Properties, I don't see MyNumber. When I reference and use this control in another project, there is an access to it's properties. I've tried to competly reinstall VS 2010 environment, including SP1, but with no success. Do you have any idea what can be wrong? By the way: none of these attributes are working, either: [Browsable(true)] [EditorBrowsable(EditorBrowsableState.Always)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] [Bindable(true)] Best regards, Marcin

  • Building a survey to put in a WordPress website using Python/Django

    - by chiurox
    So I've been given a task to build a survey to get data regarding time slot preferences of prospective students for a particular course. I know there are really quick solutions to this like Google Forms, SurveyMonkey, but since it's not unusually hard, I want to implement the survey myself in a totally new language as an opportunity to get started with it and also be able to customize and provide dynamic info to the users who are voting. Although I have done some stuff in PHP, C++, javascript, etc, I'm pretty new to Python+Django framework but it's something I've been meaning to get into since a long time ago. Initially, what I want is to make a grid with the days of the week as columns and time-durations as rows. In each cell I want to provide users a way to choose how strong (high/medium/low) their preference for this particular day+time is. I also want to show how many "votes" have already been cast for this particular preference because this will influence a lot in their decisions and as a result make this process easier when we are going to define the classes. I'll probably store the data in MySQL. Could anyone point me to some really good Python+Django tutorials for my particular purpose? Does anyone think I'm wasting my time with this trivial task by choosing new tools and that I should just use something I already know (like PHP) or a free service or plugin for Wordpress? Thanks!

  • JPA returning null for deleted items from a set

    - by Jon
    This may be related to my question from a few days ago, but I'm not even sure how to explain this part. (It's an entirely different parent-child relationship.) In my interface, I have a set of attributes (Attribute) and valid values (ValidValue) for each one in a one-to-many relationship. In the Spring MVC frontend, I have a page for an administrator to edit these values. Once it's submitted, if any of these fields (as <input> tags) are blank, I remove the ValidValue object like so: Set<ValidValue> existingValues = new HashSet<ValidValue>(attribute.getValidValues()); Set<ValidValue> finalValues = new HashSet<ValidValue>(); for(ValidValue validValue : attribute.getValidValues()) { if(!validValue.getValue().isEmpty()) { finalValues.add(validValue); } } existingValues.removeAll(finalValues); for(ValidValue removedValue : existingValues) { getApplicationDataService().removeValidValue(removedValue); } attribute.setValidValues(finalValues); getApplicationDataService().modifyAttribute(attribute); The problem is that while the database is updated appropriately, the next time I query for the Attribute objects, they're returned with an extra entry in their ValidValue set -- a null, and thus, the next time I iterate through the values to display, it shows an extra blank value in the middle. I've confirmed that this happens at the point of a merge or find, at the point of "Execute query ReadObjectQuery(entity.Attribute). Here's the code I'm using to modify the database (in the ApplicationDataService): public void modifyAttribute(Attribute attribute) { getJpaTemplate().merge(attribute); } public void removeValidValue(ValidValue removedValue) { ValidValue merged = getJpaTemplate().merge(removedValue); getJpaTemplate().remove(merged); } Here are the relevant parts of the entity classes: Entity @Table(name = "attribute") public class Attribute { @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "attribute") private Set<ValidValue> validValues = new HashSet<ValidValue>(0); } @Entity @Table(name = "valid_value") public class ValidValue { @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "attr_id", nullable = false) private Attribute attribute; }

  • Retrieving a unique result set with Core Data

    - by randombits
    I have a core data based app that manages a bunch of entities. I'm looking to be able to do the following. I have an entity "SomeEntity" with the attributes: name, type, rank, foo1, foo2. Now, SomeEntity has several rows if when we're speaking strictly in SQL terms. What I'm trying to accomplish is to retrieve only available types, even though each instance can have duplicate types. I also need them returned in order according to rank. So in SQL, what I'm looking for is the following: SELECT DISTINCT(type) ORDER BY rank ASC Here is the code I have so far that's breaking: NSError *error = NULL; NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setReturnsDistinctResults:YES]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObjects:@"type", @"rank", nil]]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"SomeEntity" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // sort by rank NSSortDescriptor *rankDescriptor = [[NSSortDescriptor alloc] initWithKey:@"rank" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:rankDescriptor,nil]; [fetchRequest setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [rankDescriptor release]; NSArray *fetchResults = [managedObjectContext executeFetchRequest:fetchRequest error:&error]; [fetchRequest release]; return fetchResults; Right now that is crashing with the following: Invalid keypath section passed to setPropertiesToFetch:

  • What are the best software/website UI design you have even seen?

    - by Edwin
    What are the best UI design in terms of usability and esthetics you have even seen? I mean both desktop software (of all OS) and website. My list: Picasa 3 - the way it organizes photos. Find-and-highlight-as-you-type in google Chrome. Dynamic search hints when entering something in the search box in Gmail. I'm not a Mac OS X user, but I have seen in most windows on the top toolbar there are both the icons and texts shown for each function, as apposed to on Windows I have seen many programs (MS Office included) have many small toolbar icons which you can hardly understand what they do until you hover the mouse on it for a while to see the hints (if any). The ability to search an setting in Eclipse IDE. the way to make 3D models in Google Sketchup. the way to label an email in Gmail. What are you list? Well, I couldn't resist to list some annoying UI design I have experienced and remember at this moment. IE on Windows server, when you visit the new website, you have to click many times to get it added to the white list before you can start browsing, IIRC, it's not fixed in IE 8 when that last time I used it on Windows 2008. The default search behavior in the File Explorer on Windows xp, that animated thing... the dialog that shows up when you are trying to save a plain text CSV file in Excel after applied some formatting options which does not compatible with CSV.

  • OrderBy Linq.Expression as parameter = (Of Func(Of T,IComparable)) to perform LinqToEntity is not working

    - by NicoJuicy
    I'd like to get this working: Call: (Count & Page are used for pagination, so Count = 20 and Page = 1 for example, for the first 20 values). Sorting should be by name LeverancierService.GetLeveranciers(Function(el) el.Name, Count, Page) Equivalent in c#: LeverancierService.GetLeveranciers(el= el.Name, Count, Page) Method that gives an error (parameters shown above): Public Overridable Function GetAllPaged(orderby As Expression(Of Func(Of T, IComparable)), ByVal Count As Integer, ByVal Page As Integer) As IEnumerable(Of T) Return dbset.OrderBy(orderby).Skip((Page - 1) * Count).Take(Count).ToList() End Function Already tried changing it to this, but it gives the same error: Public Overridable Function GetAllPaged(Of TOrderBy)(orderby As Expression(Of Func(Of T, TOrderBy)), ByVal Count As Integer, ByVal Page As Integer) As IEnumerable(Of T) Return dbset.OrderBy(orderby).Skip((Page - 1) * Count).Take(Count).ToList() End Function Error: Unable to cast the type 'System.String' to type 'System.IComparable'. LINQ to Entities only supports casting Entity Data Model primitive types. Any idea how to do this? Extra info: I'm in a DDD-layered application, so the parameter should stay the same as the called method is an overridden interface (eg. if i change this, i have to do this for 200 times or so, because it's in VB.Net and not in C# (= 1 change) ) I know there is a way to change the expression to a string and then use DLinq (= Dynamic Linq), but that's not how it should be.

  • What's the best way to communicate the purpose of a string parameter in a public API?

    - by Dave
    According to the guidance published in New Recommendations for Using Strings in Microsoft .NET 2.0, the data in a string may exhibit one of the following types of behavior: A non-linguistic identifier, where bytes match exactly. A non-linguistic identifier, where case is irrelevant, especially a piece of data stored in most Microsoft Windows system services. Culturally-agnostic data, which still is linguistically relevant. Data that requires local linguistic customs. Given that, I'd like to know the best way to communicate which behavior is expected of a string parameter in a public API. I wasn't able to find an answer in the Framework Design Guidelines. Consider the following methods: f(string this_is_a_linguistic_string) g(string this_is_a_symbolic_identifier_so_use_ordinal_compares) Is variable naming and XML documentation the best I can do? Could I use attributes in some way to mark the requirements of the string? Now consider the following case: h(Dictionary<string, object> dictionary) Note that the dictionary instance is created by the caller. How do I communicate that the callee expects the IEqualityComparer<string> object held by the dictionary to perform, for example, a case-insensitive ordinal comparison?

  • Hibernate NamingStrategy implementation that maintains state between calls

    - by Robert Petermeier
    Hi, I'm working on a project where we use Hibernate and JBoss 5.1. We need our entity classes to be mapped to Oracle tables that follow a certain naming convention. I'd like to avoid having to specify each table and column name in annotations. Therefore, I'm currently considering implementing a custom implementation of org.hibernate.cfg.NamingStrategy. The SQL naming conventions require the name of columns to have a suffix that is equivalent to a prefix of the table name. If there is a table "T100_RESOURCE", the ID column would have to be named "RES_ID_T100". In order to implement this in a NamingStrategy, the implementation would have to maintain state, i.e. the current class name it is creating the mappings for. It would rely on Hibernate to always call classToTableName() before propertyToColumnName() and to determine all column names by calling propertyToColumnName() before the next call to classToTableName() Is it safe to do that or are there situations where Hibernate will mix things up? I am not thinking of problems through multiple threads here (which can be solved by keeping the last class name in a ThreadLocal) but also of Hibernate deliberately calling this out of order in certain circumstances. For example Hibernate asking for mappings of three properties of class A, then one of class B, then again more attributes of class A.

  • Memory allocation for a matrix in C

    - by Snogzvwtr
    Why is the following code resulting in Segmentation fault? (I'm trying to create two matrices of the same size, one with static and the other with dynamic allocation) #include <stdio.h> #include <stdlib.h> //Segmentation fault! int main(){ #define X 5000 #define Y 6000 int i; int a[X][Y]; int** b = (int**) malloc(sizeof(int*) * X); for(i=0; i<X; i++){ b[i] = malloc (sizeof(int) * Y); } } Weirdly enough, if I comment out one of the matrix definitions, the code runs fine. Like this: #include <stdio.h> #include <stdlib.h> //No Segmentation fault! int main(){ #define X 5000 #define Y 6000 int i; //int a[X][Y]; int** b = (int**) malloc(sizeof(int*) * X); for(i=0; i<X; i++){ b[i] = malloc (sizeof(int) * Y); } } or #include <stdio.h> #include <stdlib.h> //No Segmentation fault! int main(){ #define X 5000 #define Y 6000 int i; int a[X][Y]; //int** b = (int**) malloc(sizeof(int*) * X); //for(i=0; i<X; i++){ // b[i] = malloc (sizeof(int) * Y); //} } I'm running gcc on Linux on a 32-bit machine.

  • Paperclip: Stay put on edit

    - by EricR
    When a user edits something in my application, they're forced to re-upload their image via paperclip even if they aren't changing it. Failing to do so will cause an error, since I validate_presence_of :image. This is quite annoying. How can I make it so Paperclip won't update its attributes if a user simply doesn't supply a new image on an edit? The photo controller is fresh out of Rails' scaffold generator. The rest of the source code is provided below. models/accommodation.rb class Accommodation < ActiveRecord::Base attr_accessible :photo validates_presence_of :photo has_one :photo has_many :notifications belongs_to :user accepts_nested_attributes_for :photo, :allow_destroy => true end controllers/accommodation_controller.rb class AccommodationsController < ApplicationController def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def new @accommodation = current_user.accommodations.build @accommodation.build_photo end def create @accommodation = current_user.accommodations.build(params[:accommodation]) if @accommodation.save flash[:notice] = "Successfully created your accommodation." redirect_to @accommodation else @accommodation.build_photo render :new end end def edit @accommodation = Accommodation.find(params[:id]) @accommodation.build_photo rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." redirect_to @accommodation else @accommodation.build_photo render :edit end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end end models/photo.rb class Photo < ActiveRecord::Base attr_accessible :image, :primary belongs_to :accommodation has_attached_file :image, :styles => { :thumb=> "100x100#", :small => "150x150>" } end

  • Division of text follow the cursor via Javascript/Jquery

    - by webzide
    Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.
