  • ActiveMQ AJax Client

    - by Lily
    I try to write a simple Ajax client to send and receive messages. It's successfully deployed but I have never received msg from the client. I am beating myself to think out what I am missing, but still can't make it work. Here is my code: I creat a dynamic web application named: ActiveMQAjaxService and put activemq-web.jar and all neccessary dependencies in the WEB-INF/lib folder. In this way, AjaxServlet and MessageServlet will be deployed I start activemq server in command line: ./activemq = activemq successfully created and display: Listening for connections at: tcp://lilyubuntu:61616 INFO | Connector openwire Started INFO | ActiveMQ JMS Message Broker (localhost, ID:lilyubuntu-56855-1272317001405-0:0) started INFO | Logging to org.slf4j.impl.JCLLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog INFO | jetty-6.1.9 INFO | ActiveMQ WebConsole initialized.

I can run the demo portfolioPublisher demo successfully at http://localhost:8161/demo/portfolio/portfolio.html, and see the numbers updated all the time. But for my simple web-app, nothing really works. Any suggestion/hint is welcomed. Thanks so much Lily

  • Designing Web Service Using Ruby on Rails - Mapping ActiveRecord Models

    - by michaeldelorenzo
    I've put together a RoR application and would now like to publish a RESTful web service for interacting with my application. I'm not sure where to go exactly, I don't want to simply expose my ActiveRecord models since there is some data on each model that isn't needed or shouldn't be exposed via an API like this. I also don't want to create a SOAP solution. My application is built using Rails 2.3.5 and I hope to move to Rails 3.0 soon after its released. I'm basically looking for a way to map my ActiveRecord models to "models" that would be exposed via the web service. Is ActiveResource the correct thing to use? What about ActionWebService?

  • Evaluating points in time by months, but without referencing years in Rails

    - by MikeH
    FYI, There is some overlap in the initial description of this question with a question I asked yesterday, but the question is different. My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product. We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date. Including years doesn't make sense for our model. So we're using the option: discard_year => true When you use discard_year => true, Rails sets a year in the database, it just doesn't appear in the views. Rails sets all the years to either 0001 or 0002 in our app. Yes, we could make it 2009 and 2010 or any other pair. But the point is that we want the months and days to function independent of a particular year. If we used 2009 and 2010, then those dates would be wrong next year because we don't expect these records to be updated every year. My problem is that we need to dynamically evaluate the availability of products based on their relationship to the current month. For example, assume it's March 15. Regardless of the year, I need a method that can tell me that a product available from October to January is not available right now. If we were using actual years, this would be pretty easy. For example, in the products model, I can do this: def is_available? (season_start.past? && season_end.future?) end I can also evaluate a start_date and an end_date against current_date However, in setup I've described above where we have arbitrary years that only make sense relative to each other, these methods don't work. For example, is_available? would return false for all my products because their end date is in the year 0001 or 0002. What I need is a method just like the ones I used as examples above, except that they evaluate against current_month instead of current_date, and past? and future months instead of years. I have no idea how to do this or whether Rails has any built in functionality that could help. I've gone through all the date and time methods/helpers in the API docs, but I'm not seeing anything equivalent to what I'm describing. Thanks.

  • rails nested attributes

    - by user342798
    I am using rails 3.0.0.beta3 and I am trying to implement form with nested attributes using :accepts_nested_attributes_for. My form is nested to three levels: Survey Question Answer. Survey has_many Questions, and Question has many Answers. Inside the Survey model, there is :accepts_nested_attributes_for :questions and inside the question mode, there is :accepts_nested_attributes_for :answers Everything is working fine except when I add a new answer to an existing question, it doesn't get created. However, if I make changes to the corresponding question while creating the answer, I can successfully create the answer. This example is exactly similar to a railscast: http://railscasts.com/episodes/197-nested-model-form-part-2 but doesn't work in rails3 (at least in my case). Please let me know if there is any issue with nested attributes in Rails 3. Thanks in advance.

  • AJAX - Get response URL after redirect

    - by Stian
    Hello, I was wondering if there is a way to get the URL of the returned resource after a AJAX call in JavaScript? I want to use this with a form, which is in "mysite.com/users/add.html". This is a Spring MVC controller. If the validation of the form fails the controller will return the "users/add" view, but if the validation is OK it will do a redirect to "mysite.com/users/index.html", using return new ModelAndView(new RedirectView("/users/index.html")); Is there a way in JavaScript to find the URL of the returned page? Thanks, Stian

  • AJAX with Web services and ASP.NET SessionState

    - by needhelp1
    We have an application which uses ScriptManager to generate a client-side proxy which makes AJAX calls to web services. The web services being invoked live in a separate appDomain(separate cluster altogether). The problem is that our application uses a State server for storing session. I want the web services to be able to access session also. First off, does anyone see anything wrong with the client making web service calls to a separate cluster(we're hoping this would be a better approach for scalability)? I was thinking that possibly anytime there is an update to the session dictionary in one appDomain, automatically update the session in the other appDomain also(referring to the web service appDomain, don't know how to do this, only theoretical). What do others think? Thanks!

  • How to update a table row with save button using .ajax

    - by Randall
    I have a table which has one row and only one cell will be editable. I have accomplished this with the following code. $("td#effEndDate").click(function() { if (!$(this).hasClass("edit")) { var value = jQuery.trim($(this).html()); $(this).html("<input id=\"txtEdit\" type=\"text\" value=\"" + value + "\" />"); $(this).addClass("edit"); $("#txtEdit").focus(); } }); Now this is the part where i'm stuck. After the field is updated a save button must be clicked to call the proper .ajax method to update the database. But how can I compare the previous value to the current value on a button press? Since i'm not using the onblur property where I could have saved the old value and passed it to the update function.

  • Rails STI: SuperClass Model Methods called from SubClass

    - by Karl
    I would like a little confirmation that I'm doing this correctly. Using rails single table inheritance I have the following models and class method: class PhoneNumber < ActiveRecord::Base def self.qual?(number) klass = self klass.exists?(:phone_number => phone_number) end end class Bubba < PhoneNumber end class Rufus < PhoneNumber end Bubba.qual?("8005551212") Tests pass and everything seems to work properly in rails console. Just wanted to confirm that I'm not headed for future trouble by using self in the superclass PhoneNumber and using that to execute class methods on subclasses from the parent. Is there a better way?

  • Getting an empty response when calling CouchDB over ajax

    - by swilliams
    I'm new to CouchDB, so please bear with me. I have an instance of CouchDB running on a VM. I can access it just fine through the browser via futon or directly at: http://192.168.62.128:5984/articles/hot_dog Calling that URL in a browser returns the proper JSON. But, when I try to call that exact same URL via ajax, I get nothing: var ajaxUrl = 'http://192.168.62.128:5984/articles/hot_dog'; $.getJSON(ajaxUrl, null, function(data) { alert(data); }); Looking at the response header with Firebug shows me that the HTTP response was 200 and the content-length is the right size. Even the Etag matches with what is in CouchDB. But the response itself is empty! The URL is absolutely right; I've triple checked, and copy/pasted it directly (and besides it wouldn't give a 200 response if it weren't). I'm using jQuery 1.4.2, and CouchDB 0.8 What's going on?

  • Security exception with ASP.NET AJAX toolkit

    - by Rod
    I've got an ASP.NET WebForms app that I've written, which uses the ASP.NET AJAX Toolkit. I've put the MultiView control onto the web form, and it worked fine, when I had it under Vista. Well, I had to replace my machine (HD failed) and I went to Windows 7 Ultimate. I tried copying the ASP.NET app from the system (before it finally failed for good) and put it onto the Windows 7 machine. I can bring up the app fine, go to all pages, but the one with these controls on it. When I do I get the following error: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. What's going on? How do I fix it?

  • Rails Joins and include columns from joins table

    - by seth.vargo
    I don't understand how to get the columns I want from rails. I have two models - A User and a Profile. A User :has_many Profile (because users can revert back to an earlier version of their profile): > DESCRIBE users; +----------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | username | varchar(255) | NO | UNI | NULL | | | password | varchar(255) | NO | | NULL | | | last_login | datetime | YES | | NULL | | +----------------+--------------+------+-----+---------+----------------+   > DESCRIBE profiles; +----------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | user_id | int(11) | NO | MUL | NULL | | | first_name | varchar(255) | NO | | NULL | | | last_name | varchar(255) | NO | | NULL | | | . . . . . . | | . . . . . . | | . . . . . . | +----------------+--------------+------+-----+---------+----------------+ In SQL, I can run the query: > SELECT * FROM profiles JOIN users ON profiles.user_id = users.id LIMIT 1; +----+-----------+----------+---------------------+---------+---------------+-----+ | id | username | password | last_login | user_id | first_name | ... | +----+-----------+----------+---------------------+---------+---------------+-----+ | 1 | john | ****** | 2010-12-30 18:04:28 | 1 | John | ... | +----+-----------+----------+---------------------+---------+---------------+-----+ See how I get all the columns for BOTH tables JOINED together? However, when I run this same query in Rails, I don't get all the columns I want - I only get those from Profile: # in rails console >> p = Profile.joins(:user).limit(1) >> [#<Profile ...>] >> p.first_name >> NoMethodError: undefined method `first_name' for #<ActiveRecord::Relation:0x102b521d0> from /Library/Ruby/Gems/1.8/gems/activerecord-3.0.1/lib/active_record/relation.rb:373:in `method_missing' from (irb):8 # I do NOT want to do this (AKA I do NOT want to use "includes") >> p.user >> NoMethodError: undefined method `user' for #<ActiveRecord::Relation:0x102b521d0> from /Library/Ruby/Gems/1.8/gems/activerecord-3.0.1/lib/active_record/relation.rb:373:in method_missing' from (irb):9 I want to (efficiently) return an object that has all the properties of Profile and User together. I don't want to :include the user because it doesn't make sense. The user should always be part of the most recent profile as if they were fields within the Profile model. How do I accomplish this?

  • Did test server port change in Rails 2.3?

    - by kareem
    I upgraded rails to 2.3.2 from 2.1.1 yesterday and a bunch of my tests started failing. When I was running under 2.1.1, the test server was running on port 3000 so I had a HOST_DOMAIN variable that included the port - HOST_DOMAIN = "localhost.tst:3000". This is so my assert_redirected_to's would succeed. Now, however, it seems that the test server is running on port 80, so the port in HOST_DOMAIN is causing tests to fail. There's no specific reason I'm keeping the port in HOST_DOMAIN. I more want to know whether something in Rails 2.3 changed the port the test server runs on and where I can read more about why. I've searched a ton and can't find anything, so I'm going to my go-to place to ask development questions :) Thanks in advance.

  • Where are my $_FILES? Ajax Uploading

    - by Richard Testani
    I've built a form to upload images, and processed with Prototype/PHP. $('image_upload').observe('submit', function() { var params = $H(); params.set('name', $('image_title').value); params.set('from', $('from_who').value); params.set('upload_file', $('upload_file').value); new Ajax.Request('/files/upload_process.php', { method:'post', parameters: params, onSuccess: function(r) { $('uploadbox').update('<img src="/images/interface/thankyou.png" />'); } }) }); The form itself sends the data to the server, but when I try to output print_r($_FILES['upload_file']); nothing appears, not even an empty array. If I output print_r($_POST), the parameters are sent properly, but only the file name of the image. So it seems the files themselves are not being sent along. How do I handle this? Thanks Rich

  • jQuery and CodeIgniter AJAX with JSON not working

    Hello, I trying to make my first AJAX with JSON call using jQuery and CodeIgniter. But for some weird reason it's not working.

I have no idea what am I doing wrong... Need help really badly. Thank you.

  • ASP.Net AJAX controls, adding via .ashx page

    - by Matt Dawdy
    Okay, this is a continuation of a previous question of mine, but it is distinct enough to be its own question. Based on user interaction, I'm calling a .ashx handler via a jquery ajax call, and that handler is building some html for me that includes some Telerik controls like a masked textbox (masked for a phone number like "(###) ###-####". I got around all the hurdles of using Render() to get the html output of a server control even when it doesn't have a "Page" object or a ScriptHandler object. However, when I show the control to a user, I see the mask in the text of the textbox, but the mask doesn't "work" in the sense that when a user starts typing, it is as if the mask is really just text. So, my question is, after putting the html code out for a masked textbox, how do I tell whatever javascript is supposed to mask the input to really start masking on that specific control? I really hope this made sense. Please tell me if you need any clarification.
