  • Fetching only the first record in the table (via the view) without changing controller?

    - by bgadoci
    I am trying to only fetch the first record in my table for display. I am creating a site where a user can upload multiple images and attach to a post but I only want to display the first image view for each post. For further clarification posts belong_to projects. So when you are on the projects show page you see multiple posts. In this view I only want to display the first image for each post. Is there a way to do this in the view without affecting the controller (as later I want to allow users to browse all photos through the addition of a lightbox). Here is my /views/posts/_post.html.erb code: <% div_for post do %> <% post.photos.each do | photo | %> <%= image_tag(photo.data.url(:large), :alt => '') %> <%= photo.description %> <% end unless post.photos.first.new_record? rescue nil %> <%= link_to h(post.link_title), post.link %> <%= h(post.description) %> <%= link_to 'Manage this post', edit_post_path(post) %> <% end %> UPDATE: I am using a photos model to attach multiple photos to each post and using paperclip here.

  • Building a J2EE dev/test setup on a single PC

    - by John
    It's been a while since I did Java work, and even then I was never responsible for starting a large project from the very start... there were test/staging/production systems already running, etc, etc. Now I am looking to start a J2EE project from scratch on my trusty workstation, which has never been used for Java development and runs Windows 7 64bit. First of all, I'll be getting Eclipse. As far as writing the code goes I'm pretty happy. And running it through Eclipse is OK, but what I'd really want is to have a VM running MySQL and TomCat on which I can properly deploy my project and run/debug it 'remotely' from my dev PC. And I guess this should be done using Ant instead of letting Eclipse build the WAR for me, so that I don't end up with a dependence on Eclipse. I'm certain Eclipse can do this, so you hit a button and it runs Ant scripts, deploys and debugs for instance, but very hazy on it. Are there any good guides on this? I don't want to be taught Java, or even Ant, but rather the 'glue' parts like getting my test VM up and running under Windows, getting a build/test/deploy/run pipeline running through Eclipse, etc. One point, I only plan to use Windows... hosting a Windows VM on my Windwos desktop. And while I can use command-line tools like ant/svn, I'm much more a GUI person who loves IDE integration... I'd rather this didn't end up an argument about Linux or Vi, etc! I am looking for free, but am a MAPS subscriber, and run Win7 Ultimate in case that makes a difference as far as free VM solutions.

  • How do I print the Images?

    - by user1477539
    I want to print the images of the 30 nba teams drafting in the first round. However when I tell it to print it prints out the link instead of the image. How do I get it to print out the image instead of giving me the image link. Here's my code: import urllib2 from BeautifulSoup import BeautifulSoup # or if your're using BeautifulSoup4: # from bs4 import BeautifulSoup soup = BeautifulSoup(urllib2.urlopen('http://www.cbssports.com/nba/draft/mock-draft').read()) rows = soup.findAll("table", attrs = {'class': 'data borderTop'})[0].tbody.findAll("tr")[2:] for row in rows: fields = row.findAll("td") if len(fields) >= 3: anchor = row.findAll("td")[1].find("a") if anchor: print anchor

  • Password protected web content-- basic question

    - by nickpish
    I'm looking to create a password-protected section of my website that requires user login, and I'm wondering what approach would provide the simplest solution. For the most part, the site will be very simple and static-- i.e. no real requirement for a database/backend-- with the protected content contained in a single directory, which I've already configured on my server via htaccess. I guess I'm wondering ultimately if it's possible to use a script of some sort that will enable access to this protected directory via a form and thereby bypass the need for configuring a mySQL/PHP solution? Furthermore, this protected content is not exactly hyper-sensitive, but private nonetheless. Thanks much for any direction here.

  • stick element to top of page until next element of that type appears

    - by aharon
    I'm having a hard time giving a good description of this, but bear with me: If I have a page structed like this <h2>Chapter 1</h2> <p>Lots of text that has mutiple screen worths of content</p> <h2>Chapter 2</h2> <p>Lots of text...</p> I'd like to have "Chapter 1" absolutely positioned or whatever at the top of the page until the user scrolls down to where "Chapter 2" starts, at which point now "Chapter 2" is displayed at the top of the page. We can add wrapper classes and divs if needed. Solutions that use JQuery would be great.

  • Why is my CSS overriding the CSS in the Wrapper?

    - by DaveDev
    I'm trying to figure out why the text in the left navigation panel on the following page is shrinking & underlining when you mouseover in Firefox. http://fundcentre.newireland.ie/ Everything on the left & top is part of a wrapper that we inject our content into. Our content is everything from "FUND CENTRE" down. Can someone suggest something I could do to sort this issue out? Thanks.

  • How do I clear the text contents of a div in javascript?

    - by Ben
    I'm temporarily adding contents to a div,tempDiv, and adding that to a link which is appended to a div, #contentHere, that's displayed. I need to clear the contents of tempDiv so that the links aren't appended to each other, creating a string of urls that don't link to anywhere. $(document).ready(function(){ $.getJSON("data.php", function(data){ for(i = 0; i < 5; i++){ $("#tempDiv").append(data.justIn[i].dataLink+ ' '); $("#contentHere").append("<a href=\"#tempDiv\">Click to go to the div link</a>"); //I need to clear the contents of tempDiv here } }); }); Solutions to clearing the temporary contents of the div as I go?

  • Patterns for avoiding jQuery silent fails

    - by Matias
    Is there any good practice to avoid your jQuery code silently fail? For example: $('.this #is:my(complexSelector)').doSomething(); I know that every time this line get executed, the selector is intended to match at least one element, or certain amount of elements. Is there any standard or good way to validate that? I thought about something like this: var $matchedElements = $('.this #is:my(complexSelector)'); if ($matchedElements.length < 0) throw 'No matched elements'; $matchedElements.doSomething(); Also I think unit testing would be a valid option instead of messing the code. My question may be silly, but I wonder whether there is a better option than the things that I'm currently doing or not. Also, maybe I'm in the wrong way checking if any element match my selector. However, as the page continues growing, the selectors could stop matching some elements and pieces of functionality could stop working inadvertently.

  • How to work around a site forbidding me to scrape their images with PHP

    - by Petruza
    I'm scraping a site, searching for JPGs to download. Scraping the site's HTML pages works fine. But when I try getting the JPGs with CURL, copy(), fopen(), etc., I get a 403 forbiden status. I know that's because the site owners don't want their images scraped, so I understand a good answer would be just don't do it, because they don't want you to. Ok, but let's say it's ok and I try to work around this, how could this be achieved? If I get the same URL with a browser, I can open the image perfectly, it's not that my IP is banned or anything, and I'm testing the scraper one file at a time, so it's not blocking me because I make too many requests too often. From my understanding, it could be that either the site is checking for some cookies that confirm that I'm using a browser and browsing their site before I download a JPG. Or that maybe PHP is using some user agent for the requests that the server can detect and filter out. Anyway, have any idea?

  • j_security_check to SSO in different module under Oracle App Server?

    - by thebearinboulder
    I have an existing j2ee application running on Oracle App Server. It is targeted towards paying customers so the content is secured and a SSO module properly intercepts all requests for secured content. Now the company is adding a unbranded public-facing module with a number of unsecured pages. At one point the user is expected to register for a free account and log in to proceed further. Think doctors adding a public-facing site with information for potential patients, or lawyers adding a public-facing site with information for potential clients. There's some information on the session and the usual approach would be to authenticate the user, persist the session information using the now-known user id, invalidate the existing session (to prevent certain types of attacks), the reload the session information before returning to the user. I can't just persist it under the session id since that's about to change. The glitch is that the existing application already has an SSO module and I get a 404 error every time I try to direct to j_security_check. I've tried that, /sso/j_security_check, even http://localhost/sso/j_security_check, all without success. I noticed that an earlier question said that tomcat requires access to a secured page before j_security_check is even visible. I don't know if that's the case with Oracle AS. Ideas? Or is the best approach to continue arguing that we have a different user base so it would be better to handle authentication in our own module anyway?

  • $_FILES is null, $_POST is not null

    - by Cory Dee
    When I am going to upload a file, my $_POST variable knows the file name, but the $_FILES variable is null. I've used this code before, so I'm really stumped. Here's what I'm using for input: <label for="importFile">Attach Resume:</label> <input type="hidden" name="MAX_FILE_SIZE" value="10000000"> <input type="file" name="importFile" id="importFile" class="validate['required']"> And for processing: $uploaddir = "E:/Sites/OPL/2008/assets/apps/newjobs/resumes/"; $uploadfile = $uploaddir . time() . '-' . urlencode(basename($_FILES['importFile']['name'])); if (!move_uploaded_file($_FILES['importFile']['tmp_name'], $uploadfile)) { echo 'Error uploading file. Error number: ' . $_FILES['importFile']['error']; var_dump($_FILES['importFile']); echo $_POST['importFile']; die(); } Which is giving me this result: Error uploading file. Error number: NULL Maintaining The OPL Website.doc Any help would be greatly appreciated.

  • solutions for rapid front-end development?

    - by fayer
    im using mvc framework and i have learned some techniques that help me with different parts of RAD. models: doctrine/visual paradigm controllers/libraries: various design patterns now i only need to know what technique/solution i should use for the views so that i can create views more rapidly. cause i don't think it's efficient to code css/html manually, even though i understand it. its the same principle when using visual paradigm to create both my mysql database tables and doctrine model classes. i believe in using right tools will boost up development speed. so what could i use for the views to save time and energy and don't reinvent the wheel all the time? dreamweaver? any css generation tools? 960/blueprint for layout? suggestions? thanks

  • Spring 3.0 REST implementation or Jersey?

    - by hnilsen
    Hi, SO! I'm currently trying to figure out which implementation of JSR-311 I'm going to recommend further up the food chain. I've pretty much narrowed it down to two options - Spring 3.0 with it's native support for REST - or use Sun's own Jersey (Restlets might also be an option). To me it doesn't seem to be much of a difference in the actual syntax, but there might be issues with performance that I haven't figured out yet. The service is meant to replace some heavy-duty EJB's and make a RESTful Webservice instead. The load is expected to be rather high, up in the 100k users per day (max) range, but will be seriously load balanced. Thanks for all your insights.

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

  • JQuery: Read each line of an element

    - by Sarfraz
    Hello, Suppose I have this html markup: <div id="wrapper"> $(function(){ // hide all links except for the first $('ul.child:not(:first)').hide(); $("a.slide:first").css("background-color","#FF9900"); $('ul.parent a.slide').click(function(){ $('ul.parent a.slide').css("background-color","#3399FF"); $('ul.parent a.slide').mouseout(function(){ $(this).css("background-color","#3399FF"); }); $('ul.parent a.slide').mouseover(function(){ $(this).css("background-color","#66CC66"); }); }); }); </div> What is the easiest way to read each line of code present in the div. How do I extract each line of code from that div or loop over each line styling in any way I want. Thanks

  • Virtual PC (XPMode) - How to access Webserver on guest from host

    - by sannoble
    I have Windows XP running inside Windows 7 via Virtual PC (XPMode) and installed Zend Server CE on the virtual XP guest. The webserver is running and can be accessed on the guest, but I cannot access the webserver from the Win7 host. I configured a static IP address and subnet of 255.255.255.0 on the guest and can ping this IP from the guest but not from the host. The other way it works fine, i.e. I can ping the host from the guest. I can also access the internet from the virtual XP guest. I tried different Network Options in the VirtualPC settings, but nothing helps. Googling the topic I couldn't find anything helpful yet. Any idea, what I could try to access the webserver on the virtual XP guest from the Win7 host?
