• [PHP] Kohana-v3 ORM parent relationship

  - by VDVLeon

  Hi all, I just started with the version 3 of the Kohana Framework. I have worked a little with the $_has_many etc. Now I have the table pages. The primary key is pageID. The table has a column called parentPageID. Now I want to make a ORM model who, when accesed like this $page->parent->find() returns the page identified by parentPageID. I have the following already: // Settings protected $_table_name = 'pages'; protected $_primary_key = 'pageID'; protected $_has_one = array( 'parent' => array( 'model' => 'page', 'foreign_key' => 'parentPageID', ), ); But that does not work, it simply returns the first page from the table. Last query says this: SELECT `pages`.* FROM `pages` ORDER BY `pages`.`pageID` ASC LIMIT 1 Does somebody know how to solve this? I know this can: $parent = $page->parent->find($page->parentPageID); but it must be and can be cleaner (I think).

• C++ Program Flow: Sockets in an Object and the Main Function

  - by jfm429

  I have a rather tricky problem regarding C++ program flow using sockets. Basically what I have is this: a simple command-line socket server program that listens on a socket and accepts one connection at a time. When that connection is lost it opens up for further connections. That socket communication system is contained in a class. The class is fully capable of receiving the connections and mirroring the data received to the client. However, the class uses UNIX sockets, which are not object-oriented. My problem is that in my main() function, I have one line - the one that creates an instance of that object. The object then initializes and waits. But as soon as a connection is gained, the object's initialization function returns, and when that happens, the program quits. How do I somehow wait until this object is deleted before the program quits? Summary: main() creates instance of object Object listens Connection received Object's initialization function returns main() exits (!) What I want is for main() to somehow delay until that object is finished with what it's doing (aka it will delete itself) before it quits. Any thoughts?

• Is there a Firebug console -vsdoc.js?

  - by David Murdoch

  If not, does anyone care to write one? I would do it myself...but I don't have time right now...maybe next week (unless someone beats me to it). If you are bored and want to compile the vsdoc: Here is the Firebug API. Here is a blog post about the format for VS doc comments for intellisense. Here is an example vsdoc (jquery-1.4.1-vsdoc.js). I created the following because I kept typing cosnole instead of console. You can use it as a starting point (ish). console = { /// <summary> /// 1: The javascript console /// </summary> /// <returns type="Object" /> }; console.log = function (object) { /// <summary> /// Write to the console's log /// </summary> /// <returns type="null" /> /// <param name="object" type="Object"> /// Write the object to the console's log /// </param> };

• Am I going the right way to make login system secure with this simple password salting?

  - by LoVeSmItH

  I have two fields in login table password salt And I have this little function to generate salt function random_salt($h_algo="sha512"){ $salt1=uniqid(rand(),TRUE); $salt2=date("YmdHis").microtime(true); if(function_exists('dechex')){ $salt2=dechex($salt2); } $salt3=$_SERVER['REMOTE_ADDR']; $salt=$salt1.$salt2.$salt3; if(function_exists('hash')){ $hash=(in_array($h_algo,hash_algos()))?$h_algo:"sha512"; $randomsalt=hash($hash,md5($salt)); //returns 128 character long hash if sha512 algorithm is used. }else{ $randomsalt=sha1(md5($salt)); //returns 40 characters long hash } return $randomsalt; } Now to create user password I have following $userinput=$_POST["password"] //don't bother about escaping, i have done it in my real project. $static_salt="THIS-3434-95456-IS-RANDOM-27883478274-SALT"; //some static hard to predict secret salt. $salt=random_salt(); //generates 128 character long hash. $password =sha1($salt.$userinput.$static_salt); $salt is saved in salt field of database and $password is saved in password field. My problem, In function random_salt(), I m having this FEELING that I'm just making things complicated while this may not generate secure salt as it should. Can someone throw me a light whether I m going in a right direction? P.S. I do have an idea about crypt functions and like such. Just want to know is my code okay? Thanks.

• JDBC call not executing

  - by dbyrne

  I am working on one of the DAOs for a medium sized web application. Unfortunately, it contains very convoluted logic, and makes hundreds of JDBC stored proc calls in loops. This is out of my control. I am working on a method inside the DAO which makes a single JDBC call. The simplified version of what this method looks like is this: DriverManager.registerDriver(new com.sybase.jdbc2.jdbc.SybDriver()); Connection con = DriverManager.getConnection((String)connectionDetails.get("DATABASE_URL") (String)connectionDetails.get("USERID"), (String)connectionDetails.get("PASSWORD")); String sqlToExecute = "{call " + STORED_PROC + "(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}"; CallableStatement stmt = con.prepareCall(sqlToExecute); //Maybe I should try calling clearParameters here? stmt.setString(1,someData); //....Set of parameters.... if (!stmt.execute()) { //execute method never returns false } stmt.close(); Its pretty much a textbook JDBC call. All this stored proc does is insert a single row. Here is where things get crazy: This code works when you run it through a debugger line by line, but fails when you run it "full speed". Not only does it fail, but it doesn't throw any exception! The execute method always returns true. It just breezes right through the JDBC call without inserting a row to the database. If you go through the log files, copy the stored proc call and run it manually, it works (just like it does in debug mode). Whats strange is that the rest of the DAO, with all its hundreds of looped stored proc calls, works fine. My thinking is that Connection or CallableStatement is caching some value behind the scenes that is screwing things up. Has anyone ever seen anything like this before? A JDBC call failing with no exceptions? I know it will be impossible to provide a complete solution to this without seeing the whole application, I am just looking for suggestions on possible issues to investigate.

• MVC3 custom validation attribute for an "at least one is required" situation

  - by Pricey

  Hi I have found this answer already: MVC3 Validation - Require One From Group Which is fairly specific to the checking of group names and uses reflection. My example is probably a bit simpler and I was just wondering if there was a simpler way to do it. I have the below: public class TimeInMinutesViewModel { private const short MINUTES_OR_SECONDS_MULTIPLIER = 60; //public string Label { get; set; } [Range(0,24, ErrorMessage = "Hours should be from 0 to 24")] public short Hours { get; set; } [Range(0,59, ErrorMessage = "Minutes should be from 0 to 59")] public short Minutes { get; set; } /// <summary> /// /// </summary> /// <returns></returns> public short TimeInMinutes() { // total minutes should not be negative if (Hours <= 0 && Minutes <= 0) { return 0; } // multiplier operater treats the right hand side as an int not a short int // so I am casting the result to a short even though both properties are already short int return (short)((Hours * MINUTES_OR_SECONDS_MULTIPLIER) + (Minutes * MINUTES_OR_SECONDS_MULTIPLIER)); } } I want to add a validation attribute either to the Hours & Minutes properties or the class itself.. and the idea is to just make sure at least 1 of these properties (Hours OR minutes) has a value, server and client side validation using a custom validation attribute. Does anyone have an example of this please? Thanks

• Moq.Mock<T> - how to setup a method that takes an expression

  - by Paul

  I am Mocking my repository interface and am not sure how to setup a method that takes an expression and returns an object? I am using Moq and NUnit Interface: public interface IReadOnlyRepository : IDisposable { IQueryable<T> All<T>() where T : class; T Single<T>(Expression<Func<T, bool>> expression) where T : class; } Test with IQueryable already setup, but don't know how to setup the T Single: private Moq.Mock<IReadOnlyRepository> _mockRepos; private AdminController _controller; [SetUp] public void SetUp() { var allPages = new List<Page>(); for (var i = 0; i < 10; i++) { allPages.Add(new Page { Id = i, Title = "Page Title " + i, Slug = "Page-Title-" + i, Content = "Page " + i + " on page content." }); } _mockRepos = new Moq.Mock<IReadOnlyRepository>(); _mockRepos.Setup(x => x.All<Page>()).Returns(allPages.AsQueryable()); //Not sure what to do here??? _mockRepos.Setup(x => x.Single<Page>() //---- _controller = new AdminController(_mockRepos.Object); }

• Did I implement clock drift properly?

  - by David Titarenco

  I couldn't find any clock drift RNG code for Windows anywhere so I attempted to implement it myself. I haven't run the numbers through ent or DIEHARD yet, and I'm just wondering if this is even remotely correct... void QueryRDTSC(__int64* tick) { __asm { xor eax, eax cpuid rdtsc mov edi, dword ptr tick mov dword ptr [edi], eax mov dword ptr [edi+4], edx } } __int64 clockDriftRNG() { __int64 CPU_start, CPU_end, OS_start, OS_end; // get CPU ticks -- uses RDTSC on the Processor QueryRDTSC(&CPU_start); Sleep(1); QueryRDTSC(&CPU_end); // get OS ticks -- uses the Motherboard clock QueryPerformanceCounter((LARGE_INTEGER*)&OS_start); Sleep(1); QueryPerformanceCounter((LARGE_INTEGER*)&OS_end); // CPU clock is ~1000x faster than mobo clock // return raw return ((CPU_end - CPU_start)/(OS_end - OS_start)); // or // return a random number from 0 to 9 // return ((CPU_end - CPU_start)/(OS_end - OS_start)%10); } If you're wondering why I Sleep(1), it's because if I don't, OS_end - OS_start returns 0 consistently (because of the bad timer resolution, I presume). Basically, (CPU_end - CPU_start)/(OS_end - OS_start) always returns around 1000 with a slight variation based on the entropy of CPU load, maybe temperature, quartz crystal vibration imperfections, etc. Anyway, the numbers have a pretty decent distribution, but this could be totally wrong. I have no idea.

• Java getInputStream 400 errors

  - by Bill Szerdy

  When I contact a web service using a Java HttpUrlConnection it just returns a 400 Bad Request (IOException). How do I get the XML information that the server is returning; it does not appear to be in the getErrorStream of the connection nor is it in any of the exception information. When I run the following PHP code against a web service: <?php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://www.myclientaddress.com/here/" ); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 ); curl_setopt($ch, CURLOPT_POST,1 ); curl_setopt($ch, CURLOPT_POSTFIELDS,"username=ted&password=scheckler&type=consumer&id=123456789&zip=12345"); $result=curl_exec ($ch); echo $result; ?> it returns the following: <?xml version="1.0" encoding="utf-8"?> <response> <status>failure</status> <errors> <error name="RES_ZIP">Zip code is not valid.</error> <error name="ZIP">Invalid zip code for residence address.</error> </errors> </response> so I know the information exists

• Identify server that made call to web service

  - by sleepybobos

  I am working within an intranet environment. We have both a production and development sharepoint server (WSS 3). We have a 3rd party workflow product which runs on top of sharepoint. It is installed on both the production and development sharepoint servers. The workflow product can call web services I have written which are hosted on our web server. How would I have the web services determine which sharepoint server made the call to the web service, be it the production or development server? I would then use this information to server specific information from web.config or database etc. Currently the site hosting web services is setup to allow anonymous access so code such as System.Web.HttpContext.Current.User.Identity.Name; returns and empty string. If windows authenticaion is used it returns the identity of the currently logged in user, which is no user in identifying the server the call was made from. I need a push in the right direction to address what I believe is probably a common scenario please.

• Different users get the same cookie - value in .ASPXANONYMOUS

  - by Malcolm Frexner

  My site allows anonymous users. I saw that under heavy load user get sometimes profile values from other users. This happens for anonymous users. I logged the access to profile data: /// <summary> /// /// </summary> /// <param name="controller"></param> /// <returns></returns> public static string ProfileID(this Controller controller ) { if (ApplicationConfiguration.LogProfileAccess) { StringBuilder sb = new StringBuilder(); (from header in controller.Request.Headers.ToPairs() select string.Concat(header.Key, ":", header.Value, ";")).ToList().ForEach(x => sb.Append(x)); string log = string.Format("ip:{0} url:{1} IsAuthenticated:{2} Name:{3} AnonId:{4} header:{5}", controller.Request.UserHostAddress, controller.Request.Url.ToString(), controller.Request.IsAuthenticated, controller.User.Identity.Name, controller.Request.AnonymousID, sb); _log.Debug(log); } return controller.Request.IsAuthenticated ? controller.User.Identity.Name : controller.Request.AnonymousID; } I can see in the log that user realy get the same cookievalue for .ASPXANONYMOUS even if they have different IP. Just to be safe I removed dependency injection for the FormsAuthentication. I dont use OutputCaching. My web.config has this setting for authentication: <anonymousIdentification enabled="true" cookieless="UseCookies" cookieName=".ASPXANONYMOUS" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" /> <authentication mode="Forms"> <forms loginUrl="~/de/Account/Login" /> </authentication> Does anybody have an idea what else I could log or what I should have a look at?

• Java downcasting and is-A has-A relationship

  - by msharma

  HI, I have a down casting question, I am a bit rusty in this area. I have 2 clasess like this: class A{ int i; String j ; //Getters and setters} class B extends A{ String k; //getter and setter} I have a method like this, in a Utility helper class: public static A converts(C c){} Where C are objects that are retireved from the database and then converted. The problem is I want to call the above method by passing in a 'C' and getting back B. So I tried this: B bClasss = (B) Utility.converts(c); So even though the above method returns A I tried to downcast it to B, but I get a runtime ClassCastException. Is there really no way around this? DO I have to write a separate converts() method which returns a B class type? If I declare my class B like: class B { String k; A a;} // So instead of extending A it has-a A, getter and setters also then I can call my existing method like this: b.setA(Utility.converts(c) ); This way I can reuse the existing method, even though the extends relationship makes more sense. What should I do? Any help much appreciated. Thanks.

• Does unboxing just return a pointer to the value within the boxed object on the heap?

  - by Charles

  I this MSDN Magazine article, the author states (emphasis mine): Note that boxing always creates a new object and copies the unboxed value's bits to the object. On the other hand, unboxing simply returns a pointer to the data within a boxed object: no memory copy occurs. However, it is commonly the case that your code will cause the data pointed to by the unboxed reference to be copied anyway. I'm confused by the sentence I've bolded and the sentence that follows it. From everything else I've read, including this MSDN page, I've never before heard that unboxing just returns a pointer to the value on the heap. I was under the impression that unboxing would result in you having a variable containing a copy of the value on the stack, just as you began with. After all, if my variable contains "a pointer to the value on the heap", then I haven't got a value type, I've got a pointer. Can someone explain what this means? Was the author on crack? (There is at least one other glaring error in the article). And if this is true, what are the cases where "your code will cause the data pointed to by the unboxed reference to be copied anyway"? I just noticed that the article is nearly 10 years old, so maybe this is something that changed very early on in the life of .Net.

• Extracting function declarations from a PHP file

  - by byronh

  I'm looking to create an on-site API reference for my framework and application. Basically, say I have a class file model.class.php: class Model extends Object { ... code here ... // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10) { ... more code here ... } } and I want to be able to generate a reference that my developers can refer to quickly in order to know which functions are available to be called. They only need to see the comments directly above each function and the declaration line. Something like this (similar to a C++ header file): // Separates results into pages. // Returns Paginator object. final public function paginate($perpage = 10); I've done some research and this answer looked pretty good (using Reflection classes), however, I'm not sure how I can keep the comments in. Any ideas? EDIT: Sorry, but I want to keep the current comment formatting. Myself and the people who are working on the code hate the verbosity associated with PHPDocumentor. Not to mention a comment-rewrite of the entire project would take years, so I want to preserve just the // comments in plaintext.

• Matlab GUI - How to get the previous value entered from a callback function?

  - by Graham

  Hi, I know that this is probably a simple problem but I am new to Matlab GUI's and basically want to get the old value which used to be stored in the text box to replace the value which has just been entered. E.g. Text box contains a valid string, User enters invalid string, Callback func, validates input and realises new input is an error and reverts to the old previous value. How should this be implemented or done? Atm I am just using the get and set property values. Below is some sample code: function sampledist_Callback(hObject, eventdata, handles) % hObject handle to sampledist (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) % Hints: get(hObject,'String') returns contents of sampledist as text % str2double(get(hObject,'String')) returns contents of sampledist as a double input = str2double(get(hObject,'String')); if(input < 0 || input > 500) errordlg('Sampled Dist. must be > 0 and < 500','Sample Dist - Input Error'); set(handles.sampledist,'String',['10']); %<--- I would like this value 10 to be the previous entry! guidata(hObject,handles); else set(handles.sampledist,'String',['',input]); guidata(hObject,handles); end

• C socket programming: client send() but server select() doesn't see it

  - by Fantastic Fourier

  Hey all, I have a server and a client running on two different machines where the client send()s but the server doesn't seem to receive the message. The server employs select() to monitor sockets for any incoming connections/messages. I can see that when the server accepts a new connection, it updates the fd_set array but always returns 0 despite the client send() messages. The connection is TCP and the machines are separated by like one router so dropping packets are highly unlikely. I have a feeling that it's not select() but perhaps send()/sendto() from client that may be the problem but I'm not sure how to go about localizing the problem area. while(1) { readset = info->read_set; ready = select(info->max_fd+1, &readset, NULL, NULL, &timeout); } above is the server side code where the server has a thread that runs select() indefinitely. rv = connect(sockfd, (struct sockaddr *) &server_address, sizeof(server_address)); printf("rv = %i\n", rv); if (rv < 0) { printf("MAIN: ERROR connect() %i: %s\n", errno, strerror(errno)); exit(1); } else printf("connected\n"); sleep(3); char * somemsg = "is this working yet?\0"; rv = send(sockfd, somemsg, sizeof(somemsg), NULL); if (rv < 0) printf("MAIN: ERROR send() %i: %s\n", errno, strerror(errno)); printf("MAIN: rv is %i\n", rv); rv = sendto(sockfd, somemsg, sizeof(somemsg), NULL, &server_address, sizeof(server_address)); if (rv < 0) printf("MAIN: ERROR sendto() %i: %s\n", errno, strerror(errno)); printf("MAIN: rv is %i\n", rv); and this is the client side where it connects and sends messages and returns connected MAIN: rv is 4 MAIN: rv is 4 any comments or insightful insights are appreciated.

• Can't iterate over a list class in Python

  - by Vicky

  I'm trying to write a simple GUI front end for Plurk using pyplurk. I have successfully got it to create the API connection, log in, and retrieve and display a list of friends. Now I'm trying to retrieve and display a list of Plurks. pyplurk provides a GetNewPlurks function as follows: def GetNewPlurks(self, since): '''Get new plurks since the specified time. Args: since: [datetime.datetime] the timestamp criterion. Returns: A PlurkPostList object or None. ''' offset = jsonizer.conv_datetime(since) status_code, result = self._CallAPI('/Polling/getPlurks', offset=offset) return None if status_code != 200 else \ PlurkPostList(result['plurks'], result['plurk_users'].values()) As you can see this returns a PlurkPostList, which in turn is defined as follows: class PlurkPostList: '''A list of plurks and the set of users that posted them.''' def __init__(self, plurk_json_list, user_json_list=[]): self._plurks = [PlurkPost(p) for p in plurk_json_list] self._users = [PlurkUser(u) for u in user_json_list] def __iter__(self): return self._plurks def GetUsers(self): return self._users def __eq__(self, other): if other.__class__ != PlurkPostList: return False if self._plurks != other._plurks: return False if self._users != other._users: return False return True Now I expected to be able to do something like this: api = plurk_api_urllib2.PlurkAPI(open('api.key').read().strip(), debug_level=1) plurkproxy = PlurkProxy(api, json.loads) user = plurkproxy.Login('my_user', 'my_pass') ps = plurkproxy.GetNewPlurks(datetime.datetime(2009, 12, 12, 0, 0, 0)) print ps for p in ps: print str(p) When I run this, what I actually get is: <plurk.PlurkPostList instance at 0x01E8D738> from the "print ps", then: for p in ps: TypeError: __iter__ returned non-iterator of type 'list' I don't understand - surely a list is iterable? Where am I going wrong - how do I access the Plurks in the PlurkPostList?

• Why is this linq extension method hit the database twice?

  - by Pure.Krome

  Hi folks, I have an extension method called ToListIfNotNullOrEmpty(), which is hitting the DB twice, instead of once. The first time it returns one result, the second time it returns all the correct results. I'm pretty sure the first time it hits the database, is when the .Any() method is getting called. here's the code. public static IList<T> ToListIfNotNullOrEmpty<T>(this IEnumerable<T> value) { if (value.IsNullOrEmpty()) { return null; } if (value is IList<T>) { return (value as IList<T>); } return new List<T>(value); } public static bool IsNullOrEmpty<T>(this IEnumerable<T> value) { if (value != null) { return !value.Any(); } return true; } I'm hoping to refactor it so that, before the .Any() method is called, it actually enumerates through the entire list. If i do the following, only one DB call is made, because the list is already enumerated. var pewPew = (from x in whatever select x) .ToList() // This enumerates. .ToListIsNotNullOrEmpty(); // This checks the enumerated result. I sorta don't really want to call ToList() then my extension method. Any ideas, folks?

• How to cope with null results in SQL Tasks that return single rows in SSIS 2005?

  - by JSacksteder

  In a dataflow task, I can slip a rowcount into the processing flow and place the count into a variable. I can later use that variable to conditionally perform some other work if the rowcount was 0. This works well for me, but I have no corresponding strategy for sql tasks expected to return a single row. In that event, I'm returning those values into variables. If the lookup produces no rows, the sql task fails when assigning values into those variables. I can branch on that component failing, but there's a side effect of that - if I'm running the job as a SQL server agent job step, the step returns DTSER_FAILURE, causing the step to fail. I can tell the sql agent to disregard the step failure, but then I won't know if I have a legitimate error in that step. This seems harder than it should be. The only strategy I can think of is to run the same query with a count(*) aggregate and test if that returns a number 0 and if so running the query again without the count. That's ugly because I have the same query in two places that I need to keep in sync. Is there a better way?

• Setting left/top position not working in IE

  - by Brian

  Hello, In a custom ASP.NET AJAX control, i have this to do some repositioning. var dims = Sys.UI.DomElement.getBounds(control); this.get_element().style.position = "absolute"; //Sys.UI.DomElement.setLocation(this.get_element(), dims.x, (dims.y + dims.height)); this.get_element().style.left = dims.x; this.get_element().style.top = (dims.y + dims.height); getBounds simply returns the x/y and width/height. I use this to set the left/top, but in IE, it's doubling; say the coordinates are 500, 20; when it sets this on the element, its actually setting to 1000, 40. Any ideas why? In firefox, this works correctly. this.get_element() returns the correct element and all, but it's not setting correctly, even though event logging says it's the correct coordinates. When using setLocation too, it doesn't work in either... What else in my code may be affecting it? JQuery isn't an option here too. Thanks.

• TypeError when using v 0.8.1 of FLOT library, but no error with v. 0.7

  - by DanielAttard

  I need some help to figure out why I am getting an error when trying to create a simple graph using the jQuery FLOT library. When I reference version 0.7 of the FLOT library, the page renders correctly: http://attardpropertytax.ca/flot07.html But when I switch to version 0.8.1 of the FLOT library, the page returns an error saying: Uncaught TypeError: Cannot read property 'left' of null http://attardpropertytax.ca/flot81.html The HTML is the same for both pages, so I cannot figure out why the new version 0.8.1 of FLOT returns an error, but the old version 0.7 does not. Any ideas? I somehow stumbled across a work-around that managed to fix my problem. I'm nut sure why, but I had to comment-out the following two sections of code from the v. 0.8.1 FLOT library: This was the first spot: // If the grid is visible, add its border width to the offset for (var a in plotOffset) { if(typeof(options.grid.borderWidth) == "object") { plotOffset[a] += showGrid ? options.grid.borderWidth[a] : 0; } else { plotOffset[a] += showGrid ? options.grid.borderWidth : 0; } } And this was the second spot: if (isNaN(v) || v < axis.min || v > axis.max // skip those lying on the axes if we got a border || (t == "full" && ((typeof bw == "object" && bw[axis.position] > 0) || bw > 0) && (v == axis.min || v == axis.max))) continue; I'm sure eventually @DNS will be taking a look at this question and maybe he will be able to help me understand what is going wrong with my code. Thanks.

• Non-normalized association with legacy tables in Rails and ActiveRecord

  - by Thomas Holmström

  I am building a Rails application accessing a legacy system. The data model contains Customers which can have one or more Subscriptions. A Subscription always belong to one and only one Customer. Though not needed, this association is represented through a join table "subscribes", which do not have an id column: Column | Type | Modifiers -----------------+---------+----------- customer_id | integer | not null subscription_id | integer | not null I have this coded as a has_and_belongs_to_many declarations in both Customer and Subscription class Customer < Activerecord::Base has_and_belongs_to_many :subscriptions, :join_table => "subscribes", :foreign_key => "customer_id", :association_foreign_key => "subscription_id" end class Subscription < Activerecord::Base has_and_belongs_to_many :customers, :join_table => "subscribes", :foreign_key => "subscription_id", :association_foreign_key => "customer_id" end The problem I have is that there can only ever be one customer for each subscription, not many, and the join table will always contain at most one row with a certain customer_id. And thus, I don't want the association "customers" on a Subscription which returns an array of (at most one) Customer, I really do want the relation "customer" which returns the Customer associated. Is there any way to force ActiveRecord to make this a 1-to-N relation even though the join table itself seems to make it an N-to-M relation? --Thomas
