• identify accounts using zend-openid [HELP]

  - by tawfekov

  Hi! , i had successfully implemented simple open ID authentication with the [gmail , yahoo , myopenid, aol and many others ] exactly as stackoverflow do but i had a problem with identifying accounts for example 'openid_ns' => string 'http://specs.openid.net/auth/2.0' (length=32) 'openid_mode' => string 'id_res' (length=6) 'openid_op_endpoint' => string 'https://www.google.com/accounts/o8/ud' (length=37) 'openid_response_nonce' => string '2010-05-02T06:35:40Z9YIASispxMvKpw' (length=34) 'openid_return_to' => string 'http://dev.local/download/index/gettingback' (length=43) 'openid_assoc_handle' => string 'AOQobUf_2jrRKQ4YZoqBvq5-O9sfkkng9UFxoE9SEBlgWqJv7Sq_FYgD7rEXiLLXhnjCghvf' (length=72) 'openid_signed' => string 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle' (length=69) 'openid_sig' => string 'knieEHpvOc/Rxu1bkUdjeE9YbbFX3lqZDOQFxLFdau0=' (length=44) 'openid_identity' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) 'openid_claimed_id' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) i thought that openid_claimed_id or openid_identity is identical for every account but after some testing turns out the claimed id is changeable by the users them self in yahoo and randomly changing in case of gmail FYI am using zend openid with a bit modification on consumer class and i can't use SERG [Simple Refistration Extension] cuz currently it uses openid v1 specification :( i hadn't read the specification of openid so if any body know please help me to how to identify openid accounts to know if this account has signed in before or not

• How can I bind a simple Javascript array to an MVC3 controller action method?

  - by Sergio Tapia

  Here is the javascript code I use to create the array and send it on it's way: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#update-cart-btn").click(function() { var items = []; $(".item").each(function () { var productKey = $(this).find("input[name='item.ProductId']").val(); var productQuantity = $(this).find("input[type='text']").val(); items[productKey] = productQuantity; }); $.ajax({ type: "POST", url: "@Url.Action("UpdateCart", "Cart")", data: items, success: function () { alert("Successfully updated your cart!"); } }); }); }); </script> The items object is properly constructed with the values I need. What data type must my object be on the backend of my controller? I tried this but the variable remains null and is not bound. [Authorize] [HttpPost] public ActionResult UpdateCart(object[] items) // items remains null. { // Some magic here. return RedirectToAction("Index"); }

• Does className exist in Mootools ?

  - by anna mae

  Hi, I want to update this very simple JS to Mootools 1.2 and it's not easy. This function : function changeclass(x){ document.getElementById("content").className = "ziclass0"; document.getElementById("content").className = "ziclass" + x; } is triggered in the DOM by : <div id="someclass"> a href="javascript: changeclass(0)">Unstyled</a a href="javascript: changeclass(1)">link one</a a href="javascript: changeclass(2)">link two</a a href="javascript: changeclass(3)">link three</a </div> to call the according CSS classes like : .ziclass1 h1{ color: rgb(142,11,0); font-family: Verdana; font-size: 2.5em; letter-spacing: 0.1em; } and changes the layout accordingly in : <div id="content" class="ziclass3"> ... </div> I know I can add an event to the triggers like : $(#someclass.each(function(element,index) { element.addEvent('click', function(){ //some code }); But, how do I get #content class classname ? Through an array ? I am a bit confused here. I'd be really grateful for any help to set me on the right track

• Focus CSS tag in Internet Explorer 8

  - by Sam

  This is driving me nuts. http://www.cssdrive.com/index.php/examples/exampleitem/focus_pseudo_class This is an example of using the hover pseudo-class. Works fine in Chrome and IE. When I save locally it works fine in Chrome but won't work in IE. What am I doing wrong!? <link rel="Stylesheet" href="style.css" /> <form> <p>1) Name:<br /> <input type="text" size="40"></p> <p>2) Email address:<br /> <input type="text" size="40"></p> <p>3) Comments:<br /> <textarea rows="5" name="comments" cols="45" wrap="virtual"></textarea></p> <p><input id="actualsubmit" type="submit" value="Submit"></p> </form> style.css: input:focus, textarea:focus{ background-color: lightyellow; }

• How would you code an efficient Circular Buffer in Java or C#

  - by Cheeso

  I want a simple class that implements a fixed-size circular buffer. It should be efficient, easy on the eyes, generically typed. EDIT: It need not be MT-capable, for now. I can always add a lock later, it won't be high-concurrency in any case. Methods should be: .Add and I guess .List, where I retrieve all the entries. On second thought, Retrieval I think should be done via an indexer. At any moment I will want to be able to retrieve any element in the buffer by index. But keep in mind that from one moment to the next Element[n] may be different, as the Circular buffer fills up and rolls over. This isn't a stack, it's a circular buffer. Regarding "overflow": I would expect internally there would be an array holding the items, and over time the head and tail of the buffer will rotate around that fixed array. But that should be invisible from the user. There should be no externally-detectable "overflow" event or behavior. This is not a school assignment - it is most commonly going to be used for a MRU cache or a fixed-size transaction or event log.

• SharePoint Web Part on Masterpage not displaying on SubSite

• Adding defaults and indexes to a script/generate command in a Rails Template?

  - by charliepark

  I'm trying to set up a Rails Template that would allow for comprehensive set-up of a specific Rails app. Using Pratik Naik's overview (http://m.onkey.org/2008/12/4/rails-templates), I was able to set up a couple of scaffolds and models, with a line that looks something like this ... generate("scaffold", "post", "title:string", "body:string") I'm now trying to add in Delayed Jobs, which normally has a migration file that looks like this: create_table :delayed_jobs, :force => true do |table| table.integer :priority, :default => 0 # Allows some jobs to jump to the front of the queue table.integer :attempts, :default => 0 # Provides for retries, but still fail eventually. table.text :handler # YAML-encoded string of the object that will do work table.text :last_error # reason for last failure (See Note below) table.datetime :run_at # When to run. Could be Time.now for immediately, or sometime in the future. table.datetime :locked_at # Set when a client is working on this object table.datetime :failed_at # Set when all retries have failed (actually, by default, the record is deleted instead) table.string :locked_by # Who is working on this object (if locked) table.timestamps end So, what I'm trying to do with the Rails template, is to add in that :default = 0 into the master template file. I know that the rest of the template's command should look like this: generate("migration", "createDelayedJobs", "priority:integer", "attempts:integer", "handler:text", "last_error:text", "run_at:datetime", "locked_at:datetime", "failed_at:datetime", "locked_by:string") Where would I put (or, rather, what is the syntax to add) the :default values in that? And if I wanted to add an index, what's the best way to do that?

• urllib2.Request() with data returns empty url

  - by Mr. Polywhirl

  My main concern is the function: getUrlAndHtml() If I manually build and append the query to the end of the uri, I can get the response.url(), but if I pass a dictionary as the request data, the url does not come back. Is there anyway to guarantee the redirected url? In my example below, if thisWorks = True I get back a url, but the returned url is the request url as opposed to a redirect link. On a sidenote, the encoding for .E2.80.93 does not translate to - for some reason? #!/usr/bin/python import pprint import urllib import urllib2 from bs4 import BeautifulSoup from sys import argv URL = 'http://en.wikipedia.org/w/index.php?' def yesOrNo(boolVal): return 'yes' if boolVal else 'no' def getTitleFromRaw(page): return page.strip().replace(' ', '_') def getUrlAndHtml(title, printable=False): thisWorks = False if thisWorks: query = 'title={:s}&printable={:s}'.format(title, yesOrNo(printable)) opener = urllib2.build_opener() opener.addheaders = [('User-agent', 'Mozilla/5.0')] response = opener.open(URL + query) else: params = {'title':title,'printable':yesOrNo(printable)} data = urllib.urlencode(params) headers = {'User-agent':'Mozilla/5.0'}; request = urllib2.Request(URL, data, headers) response = urllib2.urlopen(request) return response.geturl(), response.read() def getSoup(html, name=None, attrs=None): soup = BeautifulSoup(html) if name is None: return None return soup.find(name, attrs) def setTitle(soup, newTitle): title = soup.find('div', {'id':'toctitle'}) h2 = title.find('h2') h2.contents[0].replaceWith('{:s} for {:s}'.format(h2.getText(), newTitle)) def updateLinks(soup, url): fragment = '#' for a in soup.findAll('a', href=True): a['href'] = a['href'].replace(fragment, url + fragment) def writeToFile(soup, filename='out.html', indentLevel=2): with open(filename, 'wt') as out: pp = pprint.PrettyPrinter(indent=indentLevel, stream=out) pp.pprint(soup) print('Wrote {:s} successfully.'.format(filename)) if __name__ == '__main__': def exitPgrm(): print('usage: {:s} "<PAGE>" <FILE>'.format(argv[0])) exit(0) if len(argv) == 2: help = argv[1] if help == '-h' or help == '--help': exitPgrm() if False:''' if not len(argv) == 3: exitPgrm() ''' page = 'Led Zeppelin' # argv[1] filename = 'test.html' # argv[2] title = getTitleFromRaw(page) url, html = getUrlAndHtml(title) soup = getSoup(html, 'div', {'id':'toc'}) setTitle(soup, page) updateLinks(soup, url) writeToFile(soup, filename)

• My UITableView has duplicated rows

  - by Mark

  Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

• odd nullreference error at foreach when rendering view

  - by giddy

  This error is so weird I Just can't really figure out what is really wrong! In UserController I have public virtual ActionResult Index() { var usersmdl = from u in RepositoryFactory.GetUserRepo().GetAll() select new UserViewModel { ID = u.ID, UserName = u.Username, UserGroupName = u.UserGroupMain.GroupName, BranchName = u.Branch.BranchName, Password = u.Password, Ace = u.ACE, CIF = u.CIF, PF = u.PF }; if (usersmdl != null) { return View(usersmdl.AsEnumerable()); } return View(); } My view is of type @model IEnumerable<UserViewModel> on the top. This is what happens: Where and what exactly IS null!? I create the users from a fake repository with moq. I also wrote unit tests, which pass, to ensure the right amount of mocked users are returned. Maybe someone can point me in the right direction here? Top of the stack trace is : at lambda_method(Closure , User ) at System.Linq.Enumerable.WhereSelectArrayIterator`2.MoveNext() at ASP.Index_cshtml.Execute() Is it something to do with linq here? Tell me If I should include the full stack trace.

• How to retrieve view of MultiIndex DataFrame

  - by Henry S. Harrison

  This question was inspired by this question. I had the same problem, updating a MultiIndex DataFrame by selection. The drop_level=False solution in Pandas 0.13 will allow me to achieve the same result, but I am still wondering why I cannot get a view from the MultiIndex DataFrame. In other words, why does this not work?: >>> sat = d.xs('sat', level='day', copy=False) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python27\lib\site-packages\pandas\core\frame.py", line 2248, in xs raise ValueError('Cannot retrieve view (copy=False)') ValueError: Cannot retrieve view (copy=False) Of course it could be only because it is not implemented, but is there a reason? Is it somehow ambiguous or impossible to implement? Returning a view is more intuitive to me than returning a copy then later updating the original. I looked through the source and it seems this situation is checked explicitly to raise an error. Alternatively, is it possible to get the same sort of view from any of the other indexing methods? I've experimented but have not been successful. [edit] Some potential implementations are discussed here. I guess with the last question above I'm wondering what the current best solution is to index into arbitrary multiindex slices and cross-sections.

• Boost multi_index_container crash in release mode

  - by Zan Lynx

  I have a program that I just changed to using a boost::multi_index_container collection. After I did that and tested my code in debug mode, I was feeling pretty good about myself. However, then I compiled a release build with NDEBUG set, and the code crashed. Not immediately, but sometimes in single-threaded tests and often in multi-threaded tests. The segmentation faults happen deep inside boost insert and rotate functions related to the index updates and they are happening because a node has NULL left and right pointers. My code looks a bit like this: struct Implementation { typedef std::pair<uint32_t, uint32_t> update_pair_type; struct watch {}; struct update {}; typedef boost::multi_index_container< update_pair_type, boost::multi_index::indexed_by< boost::multi_index::ordered_unique< boost::multi_index::tag<watch>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::first> >, boost::multi_index::ordered_non_unique< boost::multi_index::tag<update>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::second> > > > update_map_type; typedef std::vector< update_pair_type > update_list_type; update_map_type update_map; update_map_type::iterator update_hint; void register_update(uint32_t watch, uint32_t update); void do_updates(uint32_t start, uint32_t end); }; void Implementation::register_update(uint32_t watch, uint32_t update) { update_pair_type new_pair( watch_offset, update_offset ); update_hint = update_map.insert(update_hint, new_pair); if( update_hint->second != update_offset ) { bool replaced _unused_ = update_map.replace(update_hint, new_pair); assert(replaced); } }

• Why are Facebook Likes Insisting on using Wrong Product Image...?

  - by Joan Kent

  Firstly, I'm not a web developer so please be patient. I have read the other posts but I think i have everything covered. My website http://www.joaniesgifts.co.uk includes the like button on the product pages. However, I've found that certain product pages are using the incorrect image when a user likes the page. For example - http://www.joaniesgifts.co.uk/terramundi-money-pots/terramundi-money-pot-holiday-fund I think this may have been down to an original incorrect setup which is now corrected. However, the problem remains... The only thing I have to go on :- if i use the facebook url linter (developers.facebook.com/tools/debug) on the above product page, I receive the following error :- Object at URL 'http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund' of type '213689662010141:product' is invalid because the domain 'www.joaniesgifts.co.uk' is not allowed for the application id '213689662010141' which owns the specified object type. If you are the owner of this application, you can verify your configured 'Site Domain' at developers.facebook.com/apps/213689662010141. (I have verified my site's domain) Everything else appears fine except it is also showing the wrong image!! However, under Raw Open Graph Document Information it has the correct link! If I then click graph api - graph.facebook.com/10150450766583352 it again shows the wrong image was linked! I've no idea what else to do - can you help me? Kind Regards, Joan PS Graph API shows the incorrect image after a scrape only minutes ago { "url": "http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund", "type": "website", "title": "Terramundi Money Pot - Holiday Fund", "image": [ { "url": "http://www.joaniesgifts.co.uk/index.php?route=product\u00252Fproduct\u00252Fcaptcha" } ], "updated_time": "2011-11-11T18:54:38+0000", "id": "10150450766583352" }

• Noob - Cycle through stored names and skip blanks

  - by ActiveJimBob

  NOOB trying to make my code more efficient. On scroll button push, the function 'SetName' stores a number to integer 'iName' which is index against 5 names stored in memory. If a name is not set in memeory, it skips to the next. The code works, but takes up a lot of room. Any advice appreciated. Code: #include <string.h> int iName = 0; int iNewName = 0; BYTE GetName () { return iName; } void SetName (int iNewName) { while (iName != iNewName) { switch (byNewName) { case 1: if (strlen (memory.m_nameA) == 0) new_name++; else iName = iNewName; break; case 2: if (strlen (memory.m_nameB) == 0) new_name++; else iName = iNewName; break; case 3: if (strlen (memory.m_nameC) == 0) new_name++; else iName = iNewName; break; case 4: if (strlen (memory.m_nameD) == 0) new_name++; else iName = iNewName; break; case 5: if (strlen (memory.m_nameE) == 0) new_name++; else iName = iNewName; break; default: iNewName = 1; break; } // end of case } // end of loop } // end of SetName function void main () { while(1) { if (Button_pushed) SetName(GetName+1); } // end of infinite loop } // end of main

• How to make ActionController::Base.asset_host and Base.relative_url_root independent?

  - by GSP

  In our Intranet environment we have a decree that common assets (stylesheets, images, etc) should be fed from Apache root while Rails apps runs from from a "sub directory" (a proxy to a Mongrel cluster). In other words: <%= stylesheet_tag '/common' %> # <link href="http://1.1.1.1/stylesheets/common.css" /> <%= link_to 'Home', :controller=>'home', :action=>'index' %> # <a href="http://1.1.1.1/myapp/" /> What I would like to do is define the assets and relative url in my configuration like this: ActionController::Base.asset_host=http://1.1.1.1 ActionController::Base.relative_url_root=/myapp But when I do this, the relative_url_root value gets appended to the asset_host value. (e.g. <link href="http://1.1.1.1/myapp/stylesheets/common.css"> ) Is there a way to stop this? And, more importantly, is there a best practice for how to deploy a rails app to an environment like this? (BTW, I don't want to simply hard code my asset paths since the development environment does not match the test and production environments.) Environment: Rails 2.3.4 Ruby 1.8.7 RedHat Linux 5.4?

• What is the complexity of this specialized sort

  - by ADB

  I would like to know the complexity (as in O(...) ) of the following sorting algorithm: there are B barrels that contains a total of N elements, spread unevenly across the barrels. the elements in each barrel are already sorted The sort takes combines all the elements from each barrel in a single sorted list: using an array of size B to store the last sorted element of each barrel (starting at 0) check each barrel (at the last stored index) and find the smallest element copy the element in the final sorted array, increment array counter increment the last sorted element for the barrel we picked from perform those steps N times or in pseudo: for i from 0 to N smallest = MAX_ELEMENT foreach b in B if bIndex[b] < b.length && b[bIndex[b]] < smallest smallest_barrel = b smallest = b[bIndex[b]] result[i] = smallest bIndex[smallest_barrel] += 1 I thought that the complexity would be O(n), but the problem I have with finding the complexity is that if B grows, it has a larger impact than if N grows because it adds another round in the B loop. But maybe that has no effect on the complexity?

• How to check for a null object reference when validating forms in MVC

  - by quakkels

  Hello SO, I'm experimenting with validating forms in the asp.net MVC framework. I'm focusing on server side validation for the time being. I've come across an error that I'm not sure how to rectify. System.NullReferenceException: Object reference not set to an instance of an object. The code that throws the error is: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create([Bind(Exclude="ID")] MembersCreate mc ) { mc.Modules = ModuleListDataContext.GetModuleList(); ViewData.Model = mc; //Validation using ModelState // // //line below errors when form field is empty // if ((string)mc.Member.Username.Trim() == "") ModelState.AddModelError("Member.Username", "Username is required."); if (!ModelState.IsValid) return View(); try { // TODO: Add insert logic here return RedirectToAction("Index","Home"); } catch { return View(); } } When I put spaces in the field it performs exactly as i want, but if I leave the field blank and press submit I get the error. What's the best way to avoid this error and still validate blank form fields? Thanks all -

• Web API Getting Http 500 error : Issue Solved See Below

  - by Joe Grasso

  Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

• Jquery Sorting by Letter

  - by Batfan

  I am using jquery to sort through a group of paragraph tags (kudos to Aaron Harun). It pulls the value "letter" (a letter) from the url string and displays only paragraphs that start with that letter. It hides all others and also consolidates the list so that there are no duplicates showing. See the code: var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ var found_first = []; jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ if(found_first[jQuery(this).text()] != true){ jQuery(this).addClass('current-series'); found_first[jQuery(this).text()] = true; }else{ jQuery(this).hide(); } } else{ jQuery(this).hide();} }) } Been working with this all day and I have 2 Questions on this: Is there a way to get it to ignore the word 'The', if it's first? For example, if a paragraph starts with 'The Amazing', I would like it to show up on the 'A' page, not the 'T' page, like it currently is. Is there a way to have a single page for (all) numbers? For example, the url to the page would be something similar to domain.com/index.php?letter=0 and this would show only the paragraph tags that start with a number, any number. I can currently do this with single numbers but, I would like 1 page for all numbers.

• jQuery + CSS Manipulation using each()

  - by atif089

  Hi, I am trying to create a css menu. I would like to remove border and padding for every last li > a element on the child ul tag. (sorry for confusing) Here is the code for the menu <ul id="nav"> <li><a id="cat1" href="#">Menu 1</a></li> <li><a id="cat2" href="#">Menu 2</a></li> <li><a id="cat3" href="#">Menu 3</a> <ul> <li><a href="#">Sub Item 1 - M3</a></li> </ul> </li> <li><a id="cat4" href="#">Menu 4</a> <ul> <li><a href="#">Sub Item 2 - M3</a></li> <li><a href="#">Sub Item 3 - M3</a></li> <li><a href="#">Sub Item 4 - M3</a></li> </ul> </li> </ul> The code must remove border and padding for last elements that is <li><a href="#">Sub Item 1 - M3</a></li> <li><a href="#">Sub Item 4 - M3</a></li> Tried this but it takes off border for only sub item 4 $("#nav li ul").each(function(index) { $("#nav li ul > :last a").css('border','0 none'); $("#nav li ul > :last a").css('padding','0'); });

• Rails can't find my route but it exists!

  - by DJTripleThreat

  Ok I have events that I want to publish/unpublish with an extra action (nonRESTful) I watched Ryan Bates' railscast on this: http://railscasts.com/episodes/35-custom-rest-actions and it got me most of the way. I think the problem is that my route is nested in an /admin section so even though when I run rake routes and get: publish_admin_event PUT /admin/events/:id/publish(.:format) {:controller=>"event_services", :action=>"publish"} This won't work in my /views/admin/index.html.erb file: <%= link_to 'Publish', publish_admin_event(event), :method => :put %> because it claims that path doesn't exist! And neither will this: <%= link_to 'Publish', {:controller => :event_services, :action => :publish}, {:method => :put, :id => event} %> and says that "No route matches {:controller=>"event_services", :action=>"publish"}" so what gives? (And I've tried restarting my server so that isn't it.) EDIT: This DOES work: <%= link_to 'Publish', "/admin/events/" + event.id.to_s + "/publish", :method => :put %> But I'd rather NOT do this.

• Rails ActionCaching with Memcached fragment hit but action gets called anyway

  - by baldtrol

  Hi stackoverflow. I'm running into something strange. I'm using memcached with a caches_action setup. I'm doing this in 4 different controllers. In two of them, it works flawlessly (so far), though admittedly those two controllers are less complicated than the two in which it doesn't seem to work. I'm doing something like this: caches_action :index, :expires_in => 6.hours, :cache_path => Proc.new {|controller| controller.send(:generate_cache_path) }, :layout => false, :if => Proc.new { |c| c.request.format.js? } The intention behind the above is to cache some results that are dependent on the params. my :generate_cache_path method just takes into account some params and session vars and creates a unique key for memcached. I can see in memcached -vv that this is working. What's weird is that I get my request from the rails app for a given key, and I see memcached (with -vv) get the request and send back the response. But then my action runs anyway, and a new value is then set for the same key, even when all the same params are given. I can watch it happen. In the controllers where everything is working, the request is made for the fragment, it gets it, and the action in the controller is halted, and the fragment is passed back. These lines come from the exact same request: Cached fragment hit: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js And then: Cached fragment miss: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js I don't know what to make of it, or if I'm doing something stupid. Any help or ideas where I could start looking for trouble would be greatly appreciated.

• Script/plugin to update web page (load next 25 comments) until page fully loaded

  - by Carl

  Brief summary: I need a script/plugin for Firefox that selects the "load next 25 comments" link at the bottom of a web page, until that link is no longer on the page. As you click that link - you get more comments - eventually all of them on the same page. See this web page for an example (there are 1,852 comments): http://www.cnn.com/2010/US/05/16/gulf.oil.spill/index.html#comment-50598247 I have a regular problem with CNN.com. I post comments there. People sometimes reply to them. I check my profile, and see the number of replies, but I can't read them there. I have to follow the link to the original article. The fist set of comments are at the bottom, with a 'load next 25' link at the bottom. There are often hundreds of comments, and sometimes a few thousand. There is no practical way for me to read the replies to my comments. If there's under around 300 hundred, I'll just click that link enough times to see what the replies to my comments are. I need a script/plugin to select that 'load next 25' link until that link is no longer present on the page. Then I could just search for my userid and read the responses.
