• What might be causing this Rails method error?

  - by Trip

  My error: Notice the undefined method '-@' . This is for a sort by. All sorts on one page break, but all the sorts on other pages use the same helper and do not break. Does it allude to something obvious?

• Editting CSS in iframe that sets Select tag's text color to black?

  - by Corey Ogburn

  This is a very specific question for a Google Chrome extension. http://www.meebo.com/mobile/ This page is where you're kicked to when you go to Meebo.com on an iPhone or Droid phone. But if you notice, the Status box where you can set yourself away or what you want your status to be has white text on a white background. In order to get a website to appear in a Google Chrome extension's popup window (the one that drops down when you click the icon next to the address bar) that isn't an included html file in the extension, I need to use an iFrame. I know that there's security measures about Cross-Site stuff like javascript and I'm not surprised I'm having trouble accessing the CSS. But there's a class, status, and it's color is white and I need to change that to black. I've tested it with Chrome's Inspect Element window and if I change that, I'll be fine. I've tried changing the manifest.json file to inject a CSS file using Content-Scripts, but nothing... I'm new to Chrome Extensions but I have experience doing web development.

• chrome extension: get specific part of the current tab page in DOM object and display it in either popup.html or new html page?

  - by sandeep

  IS there any way so that i can convert any DOM object into HTML page within the script ? suppose I have dom object like this: content script.js chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { if (request.method == "fromPopup") { console.log("got Request from Popup"); var myDivObj = document.getElementById("definition"); //sendResponse({data: "from Content Script to Popup"}); if ( myDivObj ) { sendResponse({data:myDivObj}); } else{ sendResponse({data:"Empty or No Tag"}); } console.log("sent Response1"); } else { sendResponse({}); // snub them. console.log("sent Response2"); } }); here is my popup.html <body> <Div>Searching..</Div> <Div id="output">Response??</Div> <script> console.log("Pop UP Clicked"); chrome.tabs.getSelected(null, function(tab) { chrome.tabs.sendRequest(tab.id, {method: "fromPopup", tabid: tab.id}, function(response) { console.log("got Response from Content Script"); document.getElementById("output").innerHTML=response.data; }); }); </script> </body> I know we can send onaly JSON type of data to the popup.html page.. am i right ? If yes is ther any way that I can creat HTML page with DOM Object( myDivObj ) which I collected.. Any alternative solution..? In short i want get only specific part of the current tab page in DOM object and display it in either popup.html or separate html page..

• Weird code appearing when I loop over model instances in Rails

  - by Tom Maxwell

  In my Rails app I'm trying to loop over the Submission instances inside my Folder instances with Rails templating code. It works. However, it's also returning each instance in code which doesn't seem to be JSON. It's what's returned when you look up an instance in the Rails console. Here's an example: #<Submission id: 112, title: nil, content: nil, created_at: "2013-10-10 23:29:39", updated_at: "2013-10-10 23:29:39", user_id: 1, folder_id: 1, parent_id: nil> Here's what the code looks like for the loop: <%= @folder.submissions.each do |x| %> <% if x.title != nil %> <div id="<%= x.id %>" class="submission-textual"> <h1><%= x.title %></h1> </div> <% else %> <% end %> <% end %> I checked my Folder and Submissions controllers but am not sure what this is. Why are these strings being rendered whenever I try and render an instance in my view? I'm still new to Ruby so that explains why I haven't seen this.

• Server side aggregation using Spring MVC Controllers

  - by Venu

  Hi! We have a web site with multiple pages each with lot of AJAX calls. All the Ajax calls go to a data proxy layer written in Spring 3 MVC application. In order to reduce the load on the server we are planning to aggregate calls on the client and send to the proxy layer. For ex: we have two calls /controller1/action1 and /controller2/action2 in different controllers. I want to write an aggregate controller and call it from the client instead of making two calls to the individual controllers. Something like /aggregatecontroller/aggregate (and we will post the information regarding which calls are being aggregated and required parameters). Is there any way we can call another controller/action from a controller/action and get output? The flow will be something like this: a. Call /aggregatecontroller/aggregate with info regd call1 and call2 b. aggregate action understands that it needs to aggregate call1 and call2 c. it calls /controller1/action1 and gets the response d. it calls /controller2/action2 and gets the response e. it merges both in a json response and sends it back to browser. Please let me know if you have any suggestion regd how to do this or if you think there is a better approach to do the server side aggregation. Thanks for your time.

• WPML is not detecting Wordpress custom post types

  - by janoChen

  I learned how to make custom post types with the following tutorial: http://sixrevisions.com/wordpress/wordpress-custom-post-types-guide/ It basically consist in adding this code to function.php: add_action( 'init', 'create_events' ); function create_events() { $labels = array( 'name' => _x('Events', 'post type general name'), 'singular_name' => _x('Event', 'post type singular name'), 'add_new' => _x('Add New', 'Event'), 'add_new_item' => __('Add New Event'), 'edit_item' => __('Edit Event'), 'new_item' => __('New Event'), 'view_item' => __('View Event'), 'search_items' => __('Search Events'), 'not_found' => __('No Events found'), 'not_found_in_trash' => __('No Events found in Trash'), 'parent_item_colon' => '' ); $supports = array('title', 'editor', 'custom-fields', 'revisions', 'excerpt'); register_post_type( 'event', array( 'labels' => $labels, 'public' => true, 'supports' => $supports ) ); } The WPML plugin help you to translate posts to different langauges. But this option doesn't appear in the custom post types. Any suggestions?

• integrating jquery with AJAX using MVC for ddl/html.dropdownlist

  - by needhelp

  the situation: a user on the page in question selects a category from a dropdown which then dynamically populates all the users of that category in a second dropdown beside it. all the data is being retrieved using LinqtoSQL and i was wondering if this can be done a) using html.dropdownlist in a strongly typed view? b) using jquery to trigger the ajax request on selected index change instead of a 'populate' button trigger? sorry i dont have code as what i was trying really wasnt working at all. I am having trouble with how to do it conceptually and programatically! will appreciate any links to examples etc greatly! thanks in advance! EDIT: this is kind of what i was trying to achieve.. first the ViewPage: <script type="text/javascript"> $(document).ready function TypeSearch() { $.getJSON("/Home/Type", null, function(data) { //dont know what to do here }); } </script> <p> <label for="userType">userType:</label> <%= Html.DropDownList("userType") %> <%= Html.ValidationMessage("userType", "*") %> <input type="submit" runat="server" onclick="TypeSearch()" /> <label for="accountNumber">accountNumber:</label> <%= Html.DropDownList("accountNumber") %> <%= Html.ValidationMessage("accountNumber", "*") %> </p> Then home controller action: public ActionResult Type() { string accountType = dropdownvalue; List<Account> accounts = userRep.GetAccountsByType(accountType).ToList(); return Json(accounts); }

• jQuery UI Autocomplete and CodeIgniter

  - by Kere Puki

  I am trying to implement a simple autocomplete script using jQuery UI and CodeIgniter 2 but my model keeps telling me there is an undefined variable so I dont know if my setup is right. My view $(function() { $("#txtUserSuburb").autocomplete({ source: function(request, response){ $.ajax({ url: "autocomplete/suggestions", data: { term: $("#txtUserSuburb").val() }, dataType: "json", type: "POST", success: function(data){ response(data); } }); }, minLength: 2 }); }); My controller function suggestions(){ $this->load->model('autocomplete_model'); $term = $this->input->post('term', TRUE); $rows = $this->autocomplete_model->getAutocomplete($term); echo json_encode($rows); } My Model function getAutocomplete() { $this->db->like('postcode', $term, 'after'); $query = $this->db->get('tbl_postcode'); $keywords = array(); foreach($query->result() as $row){ array_push($keywords, $row->postcode); } return $keywords; } There arent any errors except it doesn't seem to be passing the $term variable to the model.

• Perl 500 internal server error. Something wrong with my code.

  - by Nitish

  I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "<HTML>\n"; print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H2>Hello World!</H2> <br /> \n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}<p>" ; } print "</BODY>\n"; print "</HTML>\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

• C# Interface Method calls from a controller

  - by ArjaaAine

  I was just working on some application architecture and this may sound like a stupid question but please explain to me how the following works: Interface: public interface IMatterDAL { IEnumerable<Matter> GetMattersByCode(string input); IEnumerable<Matter> GetMattersBySearch(string input); } Class: public class MatterDAL : IMatterDAL { private readonly Database _db; public MatterDAL(Database db) { _db = db; LoadAll(); //Private Method } public virtual IEnumerable<Matter> GetMattersBySearch(string input) { //CODE return result; } public virtual IEnumerable<Matter> GetMattersByCode(string input) { //CODE return results; } Controller: public class MatterController : ApiController { private readonly IMatterDAL _publishedData; public MatterController(IMatterDAL publishedData) { _publishedData = publishedData; } [ValidateInput(false)] public JsonResult SearchByCode(string id) { var searchText = id; //better name for this var results = _publishedData.GetMattersBySearch(searchText).Select( matter => new { MatterCode = matter.Code, MatterName = matter.Name, matter.ClientCode, matter.ClientName }); return Json(results); } This works, when I call my controller method from jquery and step into it, the call to the _publishedData method, goes into the class MatterDAL. I want to know how does my controller know to go to the MatterDAL implementation of the Interface IMatterDAL. What if I have another class called MatterDAL2 which is based on the interface. How will my controller know then to call the right method? I am sorry if this is a stupid question, this is baffling me.

• How do I programmatically run all the JUnit tests in my Java application?

  - by Andrew McKinlay

  From Eclipse I can easily run all the JUnit tests in my application. I would like to be able to run the tests on target systems from the application jar, without Eclipse (or Ant or Maven or any other development tool). I can see how to run a specific test or suite from the command line. I could manually create a suite listing all the tests in my application, but that seems error prone - I'm sure at some point I'll create a test and forget to add it to the suite. The Eclipse JUnit plugin has a wizard to create a test suite, but for some reason it doesn't "see" my test classes. It may be looking for JUnit 3 tests, not JUnit 4 annotated tests. I could write a tool that would automatically create the suite by scanning the source files. Or I could write code so the application would scan it's own jar file for tests (either by naming convention or by looking for the @Test annotation). It seems like there should be an easier way. What am I missing?

• checking mongo database for data

  - by user1647484

  I'm playing around with this tutorial that uses Sinatra, backbone.js, and mongodb for the database. It's my first time using mongo. As far as I understand it the app uses both local storage and a database. it has these routes for the database. For example, it has these routes get '/api/:thing' do DB.collection(params[:thing]).find.to_a.map{|t| from_bson_id(t)}.to_json end get '/api/:thing/:id' do from_bson_id(DB.collection(params[:thing]).find_one(to_bson_id(params[:id]))).to_json end post '/api/:thing' do oid = DB.collection(params[:thing]).insert(JSON.parse(request.body.read.to_s)) "{\"_id\": \"#{oid.to_s}\"}" end After turning the server off and then on, I could see in the server getting data from the database routes 127.0.0.1 - - [17/Sep/2012 08:21:58] "GET /api/todos HTTP/1.1" 200 430 0.0033 My question is, how can I check from within the mongo shell whether the data's in the database? I started the mongo shell ./bin/mongo I selected the database 'use mydb' and then looking at the docs (http://www.mongodb.org/display/DOCS/Tutorial) I tried commands such as > var cursor = db.things.find(); > while (cursor.hasNext()) printjson(cursor.next()); but they didn't return anything.

• Include php code within echo from a random text

  I want to display a php code at random and so for I have <?php // load the file that contain thecode $adfile = "code.txt"; $ads = array(); // one line per code $fh = fopen($adfile, "r"); while(!feof($fh)) { $line = fgets($fh, 10240); $line = trim($line); if($line != "") { $ads[] = $line; } } // randomly pick an code $num = count($ads); $idx = rand(0, $num-1); echo $ads[$idx]; ?> The code.txt has lines like <?php print insert_proplayer( array( "width" => "600", "height" => "400" ), "http://www.youtube.com/watch?v=xnPCpCVepCg"); ?> Proplayer is a wordpress plugin that displays a video. The codes in code.txt work well, but not when I use the pick line from code.txt. Instead of the full php line I get: "width" => "600", "height" => "400" ), "http://www.youtube.com/watch?v=xnPCpCVepCg"); ?> How can I make the echo show the php code, rather than a txt version of the php code?

  I have done so much R & D for Jquery Auto complete, I found some result but not as much i needed. I am giving you code which are currently i am using . <input type="text" value="|a" name="completeMe" id="Subject" />// This input box will created by Dynamic using forloop // My Jquery Code $(function () { $("#Subject").autocomplete({ source: '/Cataloging/Bib/GetSubject', minLength: 1, select: function (event, ui) { // Do something with "ui.item.Id" or "ui.item.Name" or any of the other properties you selected to return from the action } }); }); // My Action Method public ActionResult GetSubject(string term) { term = term.Substring(2, term.Length-2); return Json(db.BibContents.Where(city => city.Value.StartsWith(term)).Select(city => city.Value), JsonRequestBehavior.AllowGet); } // My code is running with static input but while creating Dynamic I need to use live event but i don't know how can i use Live Event with this code. NOTE: I am using static value of input "|a" after rendering on action i am removing that first two char to make proper search from database. Thanks

• How do I post a link to the feed of a page via the Facebook Graph API *as* the page?

  - by jsdalton

  I'm working on a plugin for a Wordpress blog that posts a link to every article published to a Facebook Page associated with the blog. I'm using the Graph API and I have authenticated myself, for the time being, via OAuth. I can successfully post a message to the page using curl via a POST request to https://graph.facebook.com/mypageid/feed with e.g. message = "This is a test" and it published the message. The problem is that the message is "from" my user account. I'm an admin on this test page, and when I go to Facebook and post an update from the web, the link comes "from" my page. That's how I'd like this to be set up, because it looks silly if all the shared links are coming from a user account. Is there a way to authenticate myself as a page? Or is there an alternate way to POST to a page feed that doesn't end up being interpreted as a comment from a user? Thanks for any thoughts or suggestions.

• OOP/MVC advice on where to place a global helper function

  - by franko75

  Hi, I have a couple of controllers on my site which are handling form data. The forms use AJAX and I have quite a few methods across different controllers which are having to do some specific processing to return errors in a JSON encoded format - see code below. Obviously this isn't DRY and I need to move this code into a single helper function which I can use globally, but I'm wondering where this should actually go! Should I create a static helper class which contains this function (e.g Validation::build_ajax_errors()), or as this code is producing a format which is application specific and tied into the jQuery validation plugin I'm using, should it be a static method stored in, for example, my main Website controller which the form handling controllers extend from? //if ajax request, output errors if (request::is_ajax()) { //need to build errors into array form for javascript validation - move this into a helper method accessible globally $errors = $post->errors('form_data/form_error_messages'); $i = 0; $new_errors = array(); foreach ($errors as $key => $value) { $new_errors[$i][0] = '#' . $key; $new_errors[$i][1] = $value; $new_errors[$i][2] = "error"; $i++; } echo '{"jsonValidateReturn":' . json_encode($new_errors) . '}'; return; }

• How might a C# programmer approach writing a solution in javascript?

  - by Ben McCormack

  UPDATE: Perhaps this wasn't clear from my original post, but I'm mainly interested in knowing a best practice for how to structure javascript code while building a solution, not simply learning how to use APIs (though that is certainly important). I need to add functionality to a web site and our team has decided to approach the solution using a web service that receives a call from a JSON-formatted AJAX request from within the web site. The web service has been created and works great. Now I have been tasked with writing the javascript/html side of the solution. If I were solving this problem in C#, I would create separate classes for formatting the request, handling the AJAX request/response, parsing the response, and finally inserting the response somehow into the DOM. I would build properties and methods appropriately into each class, doing my best to separate functionality and structure where appropriate. However, I have to solve this problem in javascript. Firstly, how could I approach my solution in javascript in the way I would approach it from C# as described above? Or more importantly, what's a better way to approach structuring code in javascript? Any advice or links to helpful material on the web would be greatly appreciated. NOTE: Though perhaps not immediately relevant to this question, it may be worth noting that we will be using jQuery in our solution.

• Scalable Full Text Search With Per User Result Ordering

  - by jeremy

  What options exist for creating a scalable, full text search with results that need to be sorted on a per user basis? This is for PHP/MySQL (Symfony/Doctrine as well, if relevant). In our case, we have a database of workouts that have been performed by users. The workouts that the user has done before should appear at the top of the results. The more frequently they've done the workout, the higher it should appear in search matches. If it helps, you can assume we know the number of times a user has done a workout in advance. Possible Solutions Sphinx - Use Sphinx to implement full text search, do all the querying and sorting in MySQL. This seems promising (and there's a Symfony Plugin!) but I don't know much about it. Lucene - Use Lucene to perform full text search and put the users' completions into the query. As is suggested in this Stack Overflow thread. Alternatively, use Lucene to retrieve the results, then reorder them in PHP. However, both solutions seem clunky and potentially unscalable as a user may have completed hundreds of workouts. Mysql - No native full text support (InnoDB), so we'd have use LIKE or REGEX, which isn't scalable.

• 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!

• How to test a Grails Service that utilizes a criteria query (with spock)?

  - by user569825

  I am trying to test a simple service method. That method mainly just returns the results of a criteria query for which I want to test if it returns the one result or not (depending on what is queried for). The problem is, that I am unaware of how to right the corresponding test correctly. I am trying to accomplish it via spock, but doing the same with any other way of testing also fails. Can one tell me how to amend the test in order to make it work for the task at hand? (BTW I'd like to keep it a unit test, if possible.) The EventService Method public HashSet<Event> listEventsForDate(Date date, int offset, int max) { date.clearTime() def c = Event.createCriteria() def results = c { and { le("startDate", date+1) // starts tonight at midnight or prior? ge("endDate", date) // ends today or later? } maxResults(max) order("startDate", "desc") } return results } The Spock Specification package myapp import grails.plugin.spock.* import spock.lang.* class EventServiceSpec extends Specification { def event def eventService = new EventService() def setup() { event = new Event() event.publisher = Mock(User) event.title = 'et' event.urlTitle = 'ut' event.details = 'details' event.location = 'location' event.startDate = new Date(2010,11,20, 9, 0) event.endDate = new Date(2011, 3, 7,18, 0) } def "list the Events of a specific date"() { given: "An event ranging over multiple days" when: "I look up a date for its respective events" def results = eventService.listEventsForDate(searchDate, 0, 100) then: "The event is found or not - depending on the requested date" numberOfResults == results.size() where: searchDate | numberOfResults new Date(2010,10,19) | 0 // one day before startDate new Date(2010,10,20) | 1 // at startDate new Date(2010,10,21) | 1 // one day after startDate new Date(2011, 1, 1) | 1 // someday during the event range new Date(2011, 3, 6) | 1 // one day before endDate new Date(2011, 3, 7) | 1 // at endDate new Date(2011, 3, 8) | 0 // one day after endDate } } The Error groovy.lang.MissingMethodException: No signature of method: static myapp.Event.createCriteria() is applicable for argument types: () values: [] at myapp.EventService.listEventsForDate(EventService.groovy:47) at myapp.EventServiceSpec.list the Events of a specific date(EventServiceSpec.groovy:29)

• Refreshing a MKMapView when the user location is updated or using default values

  - by koichirose

  I'm trying to refresh my map view and load new data from the server when the device acquires the user location. Here's what I'm doing: - (void)viewDidLoad { CGRect bounds = self.view.bounds; mapView = [[MKMapView alloc] initWithFrame:bounds]; mapView.showsUserLocation=YES; mapView.delegate=self; [self.view insertSubview:mapView atIndex:0]; [self refreshMap]; } - (void)mapView:(MKMapView *)theMapView didUpdateUserLocation:(MKUserLocation *)userLocation { //this is to avoid frequent updates, I just need one position and don't need to continuously track the user's location if (userLocation.location.horizontalAccuracy > self.myUserLocation.location.horizontalAccuracy) { self.myUserLocation = userLocation; CLLocationCoordinate2D centerCoord = { userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude }; [theMapView setCenterCoordinate:centerCoord zoomLevel:10 animated:YES]; [self refreshMap]; } } - (void)refreshMap { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; [self.mapView removeAnnotations:self.mapView.annotations]; //default position NSString *lat = @"45.464161"; NSString *lon = @"9.190336"; if (self.myUserLocation != nil) { lat = [[NSNumber numberWithDouble:myUserLocation.coordinate.latitude] stringValue]; lon = [[NSNumber numberWithDouble:myUserLocation.coordinate.longitude] stringValue]; } NSString *url = [[NSString alloc] initWithFormat:@"http://myserver/geo_search.json?lat=%@&lon=%@", lat, lon]; NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; [url release]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; } I also have a - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data, to create and add the annotations. Here's what happens: sometimes I get the location after a while, so I already loaded data close to the default location. Then I get the location and it should remove the old annotations and add the new ones, instead I keep seeing the old annotations and the new ones are added anyway (let's say I receive 10 annotations each time, so it means that I have 20 on my map when I should have 10). What am I doing wrong?

• How to manage large amounts of delegates and usercallbacks in C# async http library

  - by Tyler

  I'm coding a .NET library in C# for communicating with XBMC via its JSON RPC interface using HTTP. I coded and released a preliminary version but everything is done synchronously. I then recoded the library to be asynchronous for my own purposes as I was/am building an XBMC remote for WP7. I now want to release the new async library but want to make sure it's nice and tidy before I do. Due to the async nature a user initiates a request, supplies a callback method that matches my delegate and then handles the response once it's been received. The problem I have is that within the library I track a RequestState object for the lifetime of the request, it contains the http request/response as well as the user callback etc. as member variables, this would be fine if only one type of object was coming back but depending on what the user calls they may be returned a list of songs or a list of movies etc. My implementation at the moment uses a single delegate ResponseDataRecieved which has a single parameter which is a simple Object - As this has only be used by me I know which methods return what and when I handle the response I cast said object to the type I know it really is - List, List etc. A third party shouldn't have to do this though - The delegate signature should contain the correct type of object. So then I need a delegate for every type of response data that can be returned to the third party - The specific problem is, how do I handle this gracefully internally - Do I have a bunch of different RequestState objects that each have a different member variable for the different delegates? That doesn't "feel" right. I just don't know how to do this gracefully and cleanly.

• How should I handle header files in a bundle?

  - by ldiqual

  I want to develop a program that relies on plugins (here: loadable bundles) to work. Multiple plugins are asked to use the same AFNetworking ressource to make network requests. However, I don't know where to put AFNetworking and CustomPluginProtocol headers. Here is how my program structure looks like for now: MyApp.xcodeproj - AFNetworking - Header.h - Plugins - Plugin1.xcodeproj - PrincipalClass.m - Plugin2.xcodeproj - PrincipalClass.m - Classes - CustomPluginProtocol.h - MainClass.m Of course, every principalClass from PluginN complies to the CustomPluginProtocol. Do the headers have to be copied in each bundle ? Can I just include the main program AFNetworking headers from my plugins ? If so (and that's what I do for now), I don't have any completion. How can I get it ? Edit Ok, so maybe I wasn't clear in my question. I want my plugins to use sources from the main application, let's say CommonClass.m and CommonClass.h. Do the plugins need CommonClass.h in their bundle, and if not, how do I enable completion when I'm in the plugin scope ?

• Rails: RESTful Find, Initialize, or Create

  - by Andrew

  I have an app that has Cities in it. I'm looking for some suggestions on how to RESTfully structure a controller so that I can lookup, initialize, and create city records via AJAX requests. For instance: Given a text field city_name A user enters the name of a City, like "Paris, France" The app checks this location to see if there is such a city in the database already If there is, it returns the city object If there is not, it returns a new record initialized with the name "Paris" and the country "France", and prompts the user to confirm they want to add this city to the database If the user says "Yes" the record is saved. If not the record is discarded and the form is cleared. Now, my first approach was to change the Create action to use find_or_create, so that an AJAX post to cities_path would result in either returning the existing city or creating it and returning it. That works ok... However, it would be better to setup controller actions that would take a string input, find , or else initialize and return, then only create if the user confirms the generated record is correct. The ideal scenario would put this all in one action so AJAX request can go to that url, the server responds with JSON objects, and javascript can handle things from there. I'd like to keep all the user-interaction logic client side, and also minimize the number of requests it takes to achieve this. Any suggestions on the cleanest, most RESTful way to accomplish this?
