  • Create Rails model with argument of associated model?

    - by Kyle Carlson
    I have two models, User and PushupReminder, and a method create_a_reminder in my PushupReminder controller (is that the best place to put it?) that I want to have create a new instance of a PushupReminder for a given user when I pass it a user ID. I have the association via the user_id column working correctly in my PushupReminder table and I've tested that I can both create reminders & send the reminder email correctly via the Rails console. Here is a snippet of the model code: class User < ActiveRecord::Base has_many :pushup_reminders end class PushupReminder < ActiveRecord::Base belongs_to :user end And the create_a_reminder method: def create_a_reminder(user) @user = User.find(user) @reminder = PushupReminder.create(:user_id => @user.id, :completed => false, :num_pushups => @user.pushups_per_reminder, :when_sent => Time.now) PushupReminderMailer.reminder_email(@user).deliver end I'm at a loss for how to run that create_a_reminder method in my code for a given user (eventually will be in a cron job for all my users). If someone could help me get my thinking on the right track, I'd really appreciate it. Thanks!

  • PHP from database and query

    - by Kyle R
    I have a table: id, affiliate Each time somebody clicks a link, a new row is inserted, ID being the ID of the page, and affiliate being the ID of the affiliate. For example: Page ID: 9 Affiliate ID: 1 Page ID: 9 Affiliate ID: 2 Page ID: 9 Affiliate ID: 3 I only have 3 affiliates. I want to select this information, and group them by affiliate, for the ID. I have tried this query: SELECT COUNT(*) FROM table WHERE id = '9' GROUP BY affiliate It works fine when I do it in php my admin, how do I get the info in PHP? I have tried: $q = mysql_query("SELECT COUNT(*) FROM table WHERE id = '" . $id . "' GROUP BY affiliate"); $r = mysql_fetch_array($q); When trying to print the data onto the page, I am only getting one result. Do I need to use a foreach/while loop to get all 3? How would I go about doing this? Thank you!

  • Why don't paid for systems work properly? [closed]

    - by Kyle Sevenoaks
    Why when you buy a online store system that's advertised as Easy for you to manage and allows to change and tweak the look of store pages with unseen ease is it exactly the opposite? When you're offered six months free support do you never get an answer and finally when you make layout changes to one page, does a completely unrelated business logic completely break down? So really two questions: Why do authors of such systems put them up for sale before they're completed? How to exact revenge on said author? Thanks.

  • How to compare Rails ''executables" before and after refactor?

    - by Kyle Heironimus
    In C, I could generate an executable, do an extensive rename only refactor, then compare executables again to confirm that the executable did not change. This was very handy to ensure that the refactor did not break anything. Has anyone done anything similar with Ruby, particularly a Rails app? Strategies and methods would be appreciated. Ideally, I could run a script that output a single file of some sort that was purely bytecode and was not changed by naming changes. I'm guessing JRuby or Rubinus would be helpful here.

  • C: Comparing two long integers (very strange)

    - by Kyle
    Hi, I have following situation (unix) : x is a long and has value 300 y is a long and has value 50000 if (x <= y) printf("Correct."); if (x > y) printf("Ouch."); Now I always get "Ouch". That means the program keeps telling me that 300 is greater than 50000! It only works again when I do if ((int)x <=(int) y) printf("Correct."); if ((int)x > (int)y) printf("Ouch."); So what is wrong with the comparison operators?

  • Best DVD Burner?

    - by davr
    I've got a fairly old generic DVD burner that doesn't support dual layer, and I'm looking to upgrade since they seem so cheap these days. Does it matter what model I get, or is it such that I can just buy whatever happens to be on sale today? Are there advantages to a certain brand over another? Basically I just want something that's fast, cheap, and produces good quality burns. Any advice would be helpful.

  • JSF 2.2 recent progress - Early Draft

    - by alexismp
    JSF specification lead Ed Burns has an update on the progress of JSF 2.2, another component which should be required as part of the upcoming Java EE 7 standard. This includes a reminder of the scope of this specification, the availability of the early draft and height specific features that are being worked on and split into "Mostly Specified Features" and "Not Yet Fully Specified Features" (I think you can read the latter as "at risk"). My favorite is "763-EverythingIsInjectable". Remember that JSF 2.2 is due out in the middle of 2012 which is in time to be integrated in the Java EE 7 platform JSR (currently scheduled for second half of 2012). In the mean time, JSF 2.2 nightly builds are available.

  • Java EE at JavaOne - A Few Picks from a Very Rich Line-up

    - by Janice J. Heiss
    A rich and diverse set of sessions cast a spotlight on Java EE at this year’s JavaOne, ranging from the popular Web Framework Smackdown, to Java EE 6 and Spring, to sessions exploring Java EE 7, and one on the implications of HTML5. Some of the world’s best EE architects and developers will be sharing their insight and expertise. If only I could be at ten places at once!BOF4149 - Web Framework Smackdown 2012    Markus Eisele - Principal IT Architect, msg systems ag    Graeme Rocher - Senior Staff Engineer, VMware    James Ward - Developer Evangelist, Heroku    Ed Burns - Consulting Member of Technical Staff, Oracle    Santiago Pericasgeertsen - Software Engineer, Oracle* Monday, Oct 1, 8:30 PM - 9:15 PM - Parc 55 - Cyril Magnin II/III Much has changed since the first Web framework smackdown, at JavaOne 2005. Or has it? The 2012 edition of this popular panel discussion surveys the current landscape of Web UI frameworks for the Java platform. The 2005 edition featured JSF, Webwork, Struts, Tapestry, and Wicket. The 2012 edition features representatives of the current crop of frameworks, with a special emphasis on frameworks that leverage HTML5 and thin-server architecture. Java Champion Markus Eisele leads the lively discussion with panelists James Ward (Play), Graeme Rocher (Grails), Edward Burns (JSF) and Santiago Pericasgeertsen (Avatar).CON6430 - Java EE and Spring Framework Panel Discussion    Richard Hightower - Developer, InfoQ    Bert Ertman - Fellow, Luminis    Gordon Dickens - Technical Architect, IT101, Inc.    Chris Beams - Senior Technical Staff, VMware    Arun Gupta - Technology Evangelist, Oracle* Tuesday, Oct 2, 10:00 AM - 11:00 AM - Parc 55 - Cyril Magnin II/III In the age of Java EE 6 and Spring 3, enterprise Java developers have many architectural choices, including Java EE 6 and Spring, but which one is right for your project? Many of us have heard the debate and seen the flame wars—it’s a topic with passionate community members, and it’s a vibrant debate. If you are looking for some level-headed discussion, grounded in real experience, by developers who have tried both, then come join this discussion. InfoQ’s Java editors moderate the discussion, and they are joined by independent consultants and representatives from both Java EE and VMWare/SpringSource.BOF4213 - Meet the Java EE 7 Specification Leads   Linda Demichiel - Consulting Member of Technical Staff, Oracle   Bill Shannon - Architect, Oracle* Tuesday, Oct 2, 5:30 PM - 6:15 PM – Parc 55 - Cyril Magnin II/III This is your chance to meet face-to-face with the engineers who are developing the next version of the Java EE platform. In this session, the specification leads for the leading technologies that are part of the Java EE 7 platform discuss new and upcoming features and answer your questions. Come prepared with your questions, your feedback, and your suggestions for new features in Java EE 7 and beyond.CON10656 - JavaEE.Next(): Java EE 7, 8, and Beyond    Ian Robinson - IBM Distinguished Engineer, IBM    Mark Little - JBoss CTO, NA    Scott Ferguson - Developer, Caucho Technology    Cameron Purdy - VP Development, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin II/IIIIn this session, hear from a distinguished panel of industry and open source luminaries regarding where they believe the Java EE community is headed, starting with Java EE 7. The focus of Java EE 7 and 8 is mostly on the cloud, specifically aiming to bring platform as a service (PaaS) providers and application developers together so that portable applications can be deployed on any cloud infrastructure and reap all its benefits in terms of scalability, elasticity, multitenancy, and so on. Most importantly, Java EE will leverage the modularization work in the underlying Java SE platform. Java EE will, of course, also update itself for trends such as HTML5, caching, NoSQL, ployglot programming, map/reduce, JSON, REST, and improvements to existing core APIs.CON7001 - HTML5 WebSocket and Java    Danny Coward - Java, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin IThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform.

  • What are the most important programming skills you need to improve as a team Leader or project manager?

    - by Aba Dov
    I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?

  • Why is my Quickly app full of fail?

    - by bstpierre
    I tried to use quickly on Ubuntu 12.04 to create an application, but it does not behave as described in that linked page. I don't get a popup when creating the application (see error below). % quickly create ubuntu-application foo Creating project directory foo Creating bzr repository and committing Launching your newly created project! (foo:16847): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Congrats, your new project is setup! cd /tmp/foo/ to start hacking. It creates a project, but when I try to run, it crashes and burns: % cd foo % quickly run (foo:22639): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Is this because I'm not using gnome-shell? What can I do to get a working project? (Edit: As a side note, I'd be willing to debug this myself, but I don't even get a traceback. What do I have to do to get quickly to give me a traceback?)

  • Should I force users to update an application?

    - by Brian Green
    I'm writing an application for a medium sized company that will be used by about 90% of our employees and our clients. In planning for the future we decided to add functionality that will verify that the version of the program that is running is a version that we still support. Currently the application will forcequit if the version is not among our supported versions. Here is my concern. Hypothetically, in version 2.0.0.1 method "A" crashes and burns in glorious fashion and method "B" works just fine. We release 2.0.0.2 to fix method A and deprecate version 0.1. Now if someone is running 0.1 to use method B they will be forced to update to fix something that isn't an issue for them right now. My question is, will the time saved not troubleshooting old, unsupported versions outweigh the cost in usability?

  • ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

    - by Bob Rhubart
    You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

  • ASP, sorting database with conditions using multiple columns...

    - by Mitch
    First of all, I'm still working in classic ASP (vbScript) with an MS Access Database. And, yes I know its archaic, but I'm still hopeful I can do this! So now to my problem: Take the following table as an example: PROJECTS ContactName StartDate EndDate Complete Mitch 2009-02-13 2011-04-23 No Eric 2006-10-01 2008-11-15 Yes Mike 2007-05-04 2009-03-30 Yes Kyle 2009-03-07 2012-07-08 No Using ASP (with VBScript), and an MS Access Database as the backend, I’d like to be able to sort this table with the following logic: I would like to sort this table by date, however, depending on whether a given project is complete or not I would like it to use either the “StartDate” or “EndDate” as the reference for a particular row. So to break it down further, this is what I’m hoping to achieve: For PROJECTS where Complete = “Yes”, reference “EndDate” for the purpose of sorting. For PROJECTS where Complete = “No”, reference “StartDate” for the purpose of sorting. So, if I were to sort the above table following these rules, the output would be: PROJECTS ContactName StartDate EndDate Complete 1 Eric 2006-10-01 2008-11-15* Yes 2 Mitch 2009-02-13* 2011-04-23 No 3 Kyle 2009-03-07* 2012-07-08 No 4 Mike 2007-05-04 2009-03-30* Yes *I’ve put a star next to the date that should be used for the sort in the table above. NOTE: This is actually a simplified version of what I really need to do, but I think that if I could just figure this out, I’ll be able to do the rest on my own. ANY HELP IS GREATLY APPRECIATED; I’VE BEEN STRUGGLING WITH THIS FOR FAR TOO LONG NOW! Thank you!
