  • Problems with multi-line comments jquery

    - by c0mrade
    Hello, I'm making a image website with a bunch of images on the website, and below every image there is possibility of commenting the image and after that comments gets displayed without page loading and the comment content, the problem is when I have long comments which break the current line they don't get displayed since my comment box css overflow is hidden. Here is example : This is a comment - This is displayed properly This is a comment This is a comment This is a comment - this is not displayed properly since it break line. Here is the jQuery code for this : $.ajax({ type: "POST", url: "<?=base_url()?>imagesform/post_comment", data: datas, success: function () { $("#image-comments-" + image_id).attr("class", "comments"); $("#image-comments-" + image_id).append("<li id=\"new_append_" + image_id+ "\">" + $("#image").find(".comment").val() + "</li>").children(':last').height($('.comments li:last').height()).hide().slideDown(500, function () { var bodyHeight = $('html').height(); $('.addComment').fadeOut(300, function () { $('html').height(bodyHeight); }); }); alert($("#image").find(".comment").val()); } }); Here the $("#image").find(".comment").val() is the value of the text-area in which comment is inputted, when I alert it the whole multi line input is there put its not being appended to the li properly, that is part when I get confused, any suggestions why only part of the inputted string is appended?

  • PHP: Formatting multi-dimensional array as HTML?

    - by Industrial
    Hi everybody, I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array as $k => $v) { if (is_array($v['children']) && !empty($v['children'])) { formatHtml($v['children']); } else { $var .= $v['cid']; } } $var.= '</div>'; return $var; } And here's my array: Array ( [1] => Array ( [cid] => 1 [_parent] => [id] => 1 [name] => 'Root category' [children] => Array ( [2] => Array ( [cid] => 2 [_parent] => 1 [id] => 3 [name] => 'Child category' [children] => Array () ) ) ) ) Thanks a lot!

  • Help me find article on Multi-threading and Event Handling in Java

    - by JDR
    I once read an article on how to properly write event handlers for multi-threading in Java, but I can't for the life of me find it anymore. It described the pitfalls and potentials for deadlocks that can occur when firing events (not Swing events mind you, but general events like model update notifications). To clarify, the situation would be as such: // let's say this is code from an MVC model somewhere public void setSomeProperty(String myProperty){ if(!this.myProperty.equals(myProperty)){ this.myProperty = myProperty; fireMyPropertyChangedEvent(...); } } The article described how passing control to arbitrary external listener code was a potential cause for deadlock. I now find myself in a situation where I need to fire such events in a multithreaded environment and I would very much like to read the article again to see what it has to say before I continue. Does anyone know the article I'm referring to? I believe it came as a (fairly short) PDF. It started off with an initial naive implementation and incrementally pointed out flaws and improved upon it. It ended with a sort of final proper-way-to-fire-multithreaded-events. I've searched endlessly in my browse history and on google, but all I could find were endless amounts topics on Swing event dispatch threads. Thank you.

  • Multi Player game using Nodejs and Socket IO

    - by Kishorevarma
    I am trying out multi player racing game using Node and Socket IO ,express . So I have tried simple example to see the latency between node server and the clients. I have a draggable image in client . when I move the image ienter code heren one client ,it has to move in all clients. so basically when I am moving the image I am sending the image position to the node server in a json format , then from there I am broadcasting to all clients. there is a ~approx 300ms latency from the time. following are the results. Client 1 sending data to server at : 286136 (timestamp) Server received at : 286271 Client2 received data at : 286470 Client3 received data at : 286479 Client4 received data at : 286487 Client5 received data at : 286520 the latency between move from client1 to client5 is 384ms. its too hight for a racing game .. here is my server code. var app = require('express').createServer(); var io = require('socket.io'); var http = require('http'); var http_server = http.createServer(); var server = http.createServer(app); server.listen(3000); var socket = io.listen(server,{ log: false }); socket.sockets.on('connection', function (client) { client.on('message', function (data){ console.log("data arrived to server",new Date().getTime()); // Below both statements are giving same latency between the client 1 and client 5 client.broadcast.emit('message',data); //socket.sockets.emit('message',data); }); }); 1) Is there any way to optimize the server code to reduce the latency? 2) is this expected latency using node and websockets ? 3) is socket io can't broadcast the data asynchronously (I mean at a same time) ? Thanks Kishorevarma

  • Tracking down origin of I/O in multi-process server

    - by Craig Ringer
    I'm currently trying to track down some phantom I/O in a PostgreSQL build I'm testing. It's a multi-process server and it isn't simple to associate disk I/O back to a particular back-end and query. I thought Linux's perf tool would be ideal for this, but I'm struggling to capture block I/O performance counter metrics and associate them with user-space activity. It's easy to record block I/O requests and completions with, eg: sudo perf record -g -T -u postgres -e 'block:block_rq_*' and the user-space pid is recorded, but there's no kernel or user-space stack captured, or ability to snapshot bits of the user-space process's heap (say, query text) etc. So while you have the pid, you don't know what the process was doing at that point. Just perf script output like: postgres 7462 [002] 301125.113632: block:block_rq_issue: 8,0 W 0 () 208078848 + 1024 [postgres] If I add the -g flag to perf record it'll take snapshots of the kernel stack, but doesn't capture user-space state for perf events captured in the kernel. The user-space stack only goes up to the entry-point from userspace, like LWLockRelease, LWLockAcquire, memcpy (mmap'd IO), __GI___libc_write, etc. So. Any tips? Being able to capture a snapshot of the user-space stack in response to kernel events would be ideal.

  • Multi-user job/task tracking/queue software

    - by Bmsgaffer86
    Background: I test and repair electronic products with a team. There are many 'jobs' going through my lab at any point in time. It is getting difficult to track whats coming in and going out because I don't do every test or repair myself. Target: User can enter a job when they drop it off in my lab, and it will appear on the master list or queue. Needs to have priorities and due dates that can be adjusted by users. Ideally this would be web based and open-source, but I am flexible. Dream: A large monitor displaying a list of jobs in the master queue with details. This is very optional though, and would be in the best case scenario. I have done MANY hours of Google-ing and I am not sure if I have been using the right terminology, but I have not found anything that is simple enough to stand alone yet complex enough to be multi-user based. I am mildly proficient in VB, and have the drive to piece anything together that I have to. I am open to ANY help or suggestions.

  • Java queue and multi-dimension array

    - by javaLearner.java
    First of all, this is my code (just started learning java): Queue<String> qe = new LinkedList<String>(); qe.add("b"); qe.add("a"); qe.add("c"); qe.add("d"); qe.add("e"); My question: Is it possible to add element to the queue with two values, like: qe.add("a","1"); // where 1 is integer So, that I know element "a" have value 1. If I want to add a number let say "2" to element a, I will have like a = 3. If this cant be done, what else in java classes that can handle this? I tried to use multi-dimention array, but its kinda hard to do the queue, like pop, push etc. (Maybe I am wrong) How to call specific element in the queue? Like, call element a, to check its value. [Note] Please don't give me links that ask me to read java docs. I was reading, and I still dont get it. The reason why I ask here is because, I know I can find the answer faster and easier.

  • Parsing a Multi-Index Excel File in Pandas

    - by rhaskett
    I have a time series excel file with a tri-level column MultiIndex that I would like to successfully parse if possible. There are some results on how to do this for an index on stack overflow but not the columns and the parse function has a header that does not seem to take a list of rows. The ExcelFile looks like is like the following: Column A is all the time series dates starting on A4 Column B has top_level1 (B1) mid_level1 (B2) low_level1 (B3) data (B4-B100+) Column C has null (C1) null (C2) low_level2 (C3) data (C4-C100+) Column D has null (D1) mid_level2 (D2) low_level1 (D3) data (D4-D100+) Column E has null (E1) null (E2) low_level2 (E3) data (E4-E100+) ... So there are two low_level values many mid_level values and a few top_level values but the trick is the top and mid level values are null and are assumed to be the values to the left. So, for instance all the columns above would have top_level1 as the top multi-index value. My best idea so far is to use transpose, but the it fills Unnamed: # everywhere and doesn't seem to work. In Pandas 0.13 read_csv seems to have a header parameter that can take a list, but this doesn't seem to work with parse.

  • Duplicate values multi array

    - by BETA911
    As the title states I'm searching for a unique solution in multi arrays. PHP is not my world so I can't make up a good and fast solution. I basically get this from the database: http://pastebin.com/vYhFCuYw . I want to check on the 'id' key, and if the array contains a duplicate 'id', then the 'aantal' should be added to each other. So basically the output has to be this: http://pastebin.com/0TXRrwLs . Thanks in advance! EDIT As asked, attempt 1 out of many: function checkDuplicates($array) { $temp = array(); foreach($array as $k) { foreach ($array as $v) { $t_id = $k['id']; $t_naam = $k['naam']; $t_percentage = $k['percentage']; $t_aantal = $k['aantal']; if ($k['id'] == $v['id']) { $t_aantal += $k['aantal']; array_push($temp, array( 'id' => $t_id, 'naam' => $t_naam, 'percentage' => $t_percentage, 'aantal' => $t_aantal, ) ); } } } return $temp; }

    We have multi-site wordpress containing more then 50 blogs/sub-site. Our base URL to wordpress site is www.example.com/base-site/ and we have other sub-sites in it like www.example.com/base-site/site1 site2 ... etc. Now My question is to redirect the main-site to one of the subsites but a simple redirect 301 is not working. I tried some solutions of mod-rewrite but its not working either for this main-site to redirect to sub-site. A solution is required to Redirect www.example.com/base-site/ to www.example.com/base-site/site1 Solution used so far but not working for me solution1 solution2

  • Operating System Not Found - BIOS recognizes, Live OS doesn't (Laptop)

    - by Klaus Borges
    Here's the deal: I have a multi-partitioned hard drive on my laptop set up with GRUB. I got a blue-screen while working on Windows 7 and when rebooting I got the Operating System Not Found error message. I rebooted the computer once again and entered the BIOS setup just to see if recognized my HDD - it did. Next step for me was booting a Live CD and seeing if I could repair GRUB or at least check if something changed on the partitions, but it doesn't seem to recognize anything there. Tried blkid, fdisk -l, not even GParted can see it. What should I do?

  • Uninstall grub from logical partition

    - by Andrew Fleenor
    I'm multi-booting with Windows 7 x64 and (at least) Linux Mint. Because I hadn't yet made a backup of my MBR, when I installed Linux mint on a logical partition, I told the installer to put GRUB on the partition instead of in the MBR. This turned out to be useless, as I need to use GRUB from a boot disk to get into the GRUB I installed... Before installing it in the MBR, I'd like to get it out of the partition, preferably without wiping and reinstalling Linux. I don't relish the prospect of going through two layers of GRUB when I want to boot Linux. How do I get it out, or what other options are available to me?

  • Combine VPN bandwith over two or more WAN connections? Load balancing?

    - by mistrfu
    Imagine you only have DSL with 5mbps Down and 2mbps Up. Is it possible to have 10 of these for example and combine them in a way that would increase the upstrean bandwidth to one server? In my head it works like this: intranet with one gateway/router router connected to multi wan load ballancer on each ballancer wan port router with vpn clinet set up, tunneling to a server ?some? software on the server in cloud joining all these connection into one interface again I would need this mostly for big uploads to a server, downlink to the office is not that important at all. Does it even make sense? I drew an image to clarify.

  • jqGrid multi-checkbox custom edittype solution

    - by gsiler
    For those of you trying to understand jqGrid custom edit types ... I created a multi-checkbox form element, and thought I'd share. This was built using version 3.6.4. If anyone has a more efficient solution, please pass it on. Within the colModel, the appropriate edit fields look like this: edittype:'custom' editoptions:{ custom_element:MultiCheckElem, custom_value:MultiCheckVal, list:'Check1,Check2,Check3,Check4' } Here are the javascript functions (BTW, It also works – with some modifications – when the list of checkboxes is in a DIV block): //———————————————————— // Description: // MultiCheckElem is the "custom_element" function that builds the custom multiple check box input // element. From what I have gathered, jqGrid calls this the first time the form is launched. After // that, only the "custom_value" function is called. // // The full list of checkboxes is in the jqGrid "editoptions" section "list" tag (in the options // parameter). //———————————————————— function MultiCheckElem( value, options ) { //———- // for each checkbox in the list // build the input element // set the initial "checked" status // endfor //———- var ctl = ''; var ckboxAry = options.list.split(','); for ( var i in ckboxAry ) { var item = ckboxAry[i]; ctl += '<input type="checkbox" '; if ( value.indexOf(item + '|') != -1 ) ctl += 'checked="checked" '; ctl += 'value="' + item + '"> ' + item + '</input><br />&nbsp;'; } ctl = ctl.replace( /<br />&nbsp;$/, '' ); return ctl; } //———————————————————— // Description: // MultiCheckVal is the "custom_value" function for the custom multiple check box input element. It // appears that jqGrid invokes this function the first time the form is submitted and, the rest of // the time, when the form is launched (action = set) and when it is submitted (action = 'get'). //———————————————————— function MultiCheckVal(elem, action, val) { var items = ''; if (action == 'get') // the form has been submitted { //———- // for each input element // if it's checked, add it to the list of items // endfor //———- for (var i in elem) { if (elem[i].tagName == 'INPUT' && elem[i].checked ) items += elem[i].value + ','; } // items contains a comma delimited list that is returned as the result of the element items = items.replace(/,$/, ''); } else // the form is launched { //———- // for each input element // based on the input value, set the checked status // endfor //———- for (var i in elem) { if (elem[i].tagName == 'INPUT') { if (val.indexOf(elem[i].value + '|') == -1) elem[i].checked = false; else elem[i].checked = true; } } // endfor } return items; }

  • printing multi dimentional array

    i have this multi dimentional array that i want to print into a table having each record/item go into its own row but it goes column wise. this is the output that im getting: http://mypetshopping.com/product.php ps: the value of $product will by dynamic based on what product is being viewed. <?php session_start(); ?> <table> <thead> <tr> <th>Name</th> <th>Hash</th> <th>Quantity</th> <th>Size</th> <th>Color</th> </tr> </thead> <tbody> <?php function addCart($product, $quantity, $size,$color) { $hash = md5($product); $_SESSION['cart'][$product]['name'] = $product; $_SESSION['cart'][$product]['hash'] = $hash; $_SESSION['cart'][$product]['quantity'] = $quantity; $_SESSION['cart'][$product]['size'] = $size; $_SESSION['cart'][$product]['color'] = $color; } addCart('Red Dress',1,'XL','red'); addCart('Blue Dress',1,'XL','blue'); addCart('Slippers',1,'XL','orange'); addCart('Green Hat',1,'XXXL','green'); $cart = $_SESSION['cart']; foreach($cart as $product => $array) { foreach($array as $key => $value) { ?> <tr> <td><?=$value;?></td> <td><?=$value;?></td> <td><?=$value;?></td> <td><?=$value;?></td> <td><?=$value;?></td> </tr> <?php } } ?>

  • Multi-threaded Pooled Allocators

    - by Darren Engwirda
    I'm having some issues using pooled memory allocators for std::list objects in a multi-threaded application. The part of the code I'm concerned with runs each thread function in isolation (i.e. there is no communication or synchronization between threads) and therefore I'd like to setup separate memory pools for each thread, where each pool is not thread-safe (and hence fast). I've tried using a shared thread-safe singleton memory pool and found the performance to be poor, as expected. This is a heavily simplified version of the type of thing I'm trying to do. A lot has been included in a pseudo-code kind of way, sorry if it's confusing. /* The thread functor - one instance of MAKE_QUADTREE created for each thread */ class make_quadtree { private: /* A non-thread-safe memory pool for int linked list items, let's say that it's * something along the lines of BOOST::OBJECT_POOL */ pooled_allocator<int> item_pool; /* The problem! - a local class that would be constructed within each std::list as the * allocator but really just delegates to ITEM_POOL */ class local_alloc { public : //!! I understand that I can't access ITEM_POOL from within a nested class like //!! this, that's really my question - can I get something along these lines to //!! work?? pointer allocate (size_t n) { return ( item_pool.allocate(n) ); } }; public : make_quadtree (): item_pool() // only construct 1 instance of ITEM_POOL per // MAKE_QUADTREE object { /* The kind of data structures - vectors of linked lists * The idea is that all of the linked lists should share a local pooled allocator */ std::vector<std::list<int, local_alloc>> lists; /* The actual operations - too complicated to show, but in general: * * - The vector LISTS is grown as a quadtree is built, it's size is the number of * quadtree "boxes" * * - Each element of LISTS (each linked list) represents the ID's of items * contained within each quadtree box (say they're xy points), as the quadtree * is grown a lot of ID pop/push-ing between lists occurs, hence the memory pool * is important for performance */ } }; So really my problem is that I'd like to have one memory pool instance per thread functor instance, but within each thread functor share the pool between multiple std::list objects.

  • Get value of element in Multi-Dimensional Array

    - by George
    Here is my foreach loop to get at the values from a multi-dimensional array $_coloredvariables = get_post_meta( $post->ID, '_coloredvariables', true ); foreach ($_coloredvariables as $key => $value) { var_dump($value); } Which outputs this: array 'label' => string 'Color' (length=5) 'size' => string 'small' (length=5) 'displaytype' => string 'square' (length=6) 'values' => array 'dark-night-angel' => array 'type' => string 'Image' (length=5) 'color' => string '#2c4065' (length=7) 'image' => string '' (length=0) 'forest-green' => array 'type' => string 'Color' (length=5) 'color' => string '#285d5f' (length=7) 'image' => string '' (length=0) 'voilet' => array 'type' => string 'Color' (length=5) 'color' => string '#6539c9' (length=7) 'image' => string '' (length=0) 'canary-yellow' => array 'type' => string 'Color' (length=5) 'color' => string 'grey' (length=4) 'image' => string '' (length=0) And then to only get the values array I can do this: foreach ($_coloredvariables as $key => $value) { var_dump($value['values']); } which outputs this: array 'dark-night-angel' => array 'type' => string 'Image' (length=5) 'color' => string '#2c4065' (length=7) 'image' => string '' (length=0) 'forest-green' => array 'type' => string 'Color' (length=5) 'color' => string '#285d5f' (length=7) 'image' => string '' (length=0) 'voilet' => array 'type' => string 'Color' (length=5) 'color' => string '#6539c9' (length=7) 'image' => string '' (length=0) 'canary-yellow' => array 'type' => string 'Color' (length=5) 'color' => string 'grey' (length=4) 'image' => string '' (length=0) What I can't figure out is how to get these elements in the array structure "dark-night-angel", "forest-green", "voilet", "canary-yellow" Without using specific names: var_dump($value['values']['dark-night-angel']) Something that is more dynamic, of course this doesn't work: var_dump($value['values'][0][0]); thanks

  • Multi-tier applications using L2S, WCF and Base Class

    - by Gena Verdel
    Hi all. One day I decided to build this nice multi-tier application using L2S and WCF. The simplified model is : DataBase-L2S-Wrapper(DTO)-Client Application. The communication between Client and Database is achieved by using Data Transfer Objects which contain entity objects as their properties. abstract public class BaseObject { public virtual IccSystem.iccObjectTypes ObjectICC_Type { get { return IccSystem.iccObjectTypes.unknownType; } } [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_ID", AutoSync = AutoSync.OnInsert, DbType = "BigInt NOT NULL IDENTITY", IsPrimaryKey = true, IsDbGenerated = true)] [global::System.Runtime.Serialization.DataMemberAttribute(Order = 1)] public virtual long ID { //get; //set; get { return _ID; } set { _ID = value; } } } [DataContract] public class BaseObjectWrapper<T> where T : BaseObject { #region Fields private T _DBObject; #endregion #region Properties [DataMember] public T Entity { get { return _DBObject; } set { _DBObject = value; } } #endregion } Pretty simple, isn't it?. Here's the catch. Each one of the mapped classes contains ID property itself so I decided to override it like this [global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.Divisions")] [global::System.Runtime.Serialization.DataContractAttribute()] public partial class Division : INotifyPropertyChanging, INotifyPropertyChanged { [global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_ID", AutoSync=AutoSync.OnInsert, DbType="BigInt NOT NULL IDENTITY", IsPrimaryKey=true, IsDbGenerated=true)] [global::System.Runtime.Serialization.DataMemberAttribute(Order=1)] public override long ID { get { return this._ID; } set { if ((this._ID != value)) { this.OnIDChanging(value); this.SendPropertyChanging(); this._ID = value; this.SendPropertyChanged("ID"); this.OnIDChanged(); } } } } Wrapper for division is pretty straightforward as well: public class DivisionWrapper : BaseObjectWrapper<Division> { } It worked pretty well as long as I kept ID values at mapped class and its BaseObject class the same(that's not very good approach, I know, but still) but then this happened: private CentralDC _dc; public bool UpdateDivision(ref DivisionWrapper division) { DivisionWrapper tempWrapper = division; if (division.Entity == null) { return false; } try { Table<Division> table = _dc.Divisions; var q = table.Where(o => o.ID == tempWrapper.Entity.ID); if (q.Count() == 0) { division.Entity._errorMessage = "Unable to locate entity with id " + division.Entity.ID.ToString(); return false; } var realEntity = q.First(); realEntity = division.Entity; _dc.SubmitChanges(); return true; } catch (Exception ex) { division.Entity._errorMessage = ex.Message; return false; } } When trying to enumerate over the in-memory query the following exception occurred: Class member BaseObject.ID is unmapped. Although I'm stating the type and overriding the ID property L2S fails to work. Any suggestions?

  • Problem parsing XML data to Multi dimensional array

    - by Cam
    Hi there, i'm still transitioning from as2 to as3, i'm having trouble with parsing XML data to Multi dimensional array, below is the onComplete handler which is succesfully tracing 'event.target.data' but outputs 'A term is undefined and has no properties' when tracing _vein_data[0][0].xPos .

  • Error when deploying site of a maven multi module project with FTP

    - by julien
    I have a multi module project. When I launch mvn site:deploy, the deployment of the base module works fine, but it fails to create the directory of the module sites on the FTP server: [INFO] Error uploading site Embedded error: Required directory: '/myremoteftprepository/myproject-mymodule' is missing When I create the missing directory by hand, it works fine, but I would like to avoid that. It is surprising that the deploy command do not create it. Do you how to force this directory creation? Is it a bug in the wagon-ftp plugin? FYI, here is my POM: <build> <extensions> <!-- Enabling the use of FTP --> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-ftp</artifactId> <version>1.0</version> </extension> </extensions> </build> I have chosen to include the javadoc with: <reporting> <plugins> <!-- include javadoc in the site --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.8</version> <configuration> <show>public</show> </configuration> </plugin> </plugins> </reporting> and <distributionManagement> <site> <id>site</id> <name>maven site</name> <url>ftp://ftp.blabla.org/myremoteftprepository</url> </site> </distributionManagement> and my settings.xml is good.

  • Entity Framework and multi-tenancy database design

    - by Junto
    I am looking at multi-tenancy database schema design for an SaaS concept. It will be ASP.NET MVC - EF, but that isn't so important. Below you can see an example database schema (the Tenant being the Company). The CompanyId is replicated throughout the schema and the primary key has been placed on both the natural key, plus the tenant Id. Plugging this schema into the Entity Framework gives the following errors when I add the tables into the Entity Model file (Model1.edmx): The relationship 'FK_Order_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderId, CompanyId}' of the table 'Order'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Order' uses the set of foreign keys '{OrderId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_Order_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderId, CompanyId}' of the table 'Order'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Customer' uses the set of foreign keys '{CustomerId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Order' uses the set of foreign keys '{OrderId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The relationship 'FK_OrderLine_Product' uses the set of foreign keys '{ProductId, CompanyId}' that are partially contained in the set of primary keys '{OrderLineId, CompanyId}' of the table 'OrderLine'. The set of foreign keys must be fully contained in the set of primary keys, or fully not contained in the set of primary keys to be mapped to a model. The question is in two parts: Is my database design incorrect? Should I refrain from these compound primary keys? I'm questioning my sanity regarding the fundamental schema design (frazzled brain syndrome). Please feel free to suggest the 'idealized' schema. Alternatively, if the database design is correct, then is EF unable to match the keys because it perceives these foreign keys as a potential mis-configured 1:1 relationships (incorrectly)? In which case, is this an EF bug and how can I work around it?

  • Marking multi-level nested forms as "dirty" in Rails

    - by Charles Kihe
    I have a three-level multi-nested form in Rails. The setup is like this: Projects have many Milestones, and Milestones have many Notes. The goal is to have everything editable within the page with JavaScript, where we can add multiple new Milestones to a Project within the page, and add new Notes to new and existing Milestones. Everything works as expected, except that when I add new notes to an existing Milestone (new Milestones work fine when adding notes to them), the new notes won't save unless I edit any of the fields that actually belong to the Milestone to mark the form "dirty"/edited. Is there a way to flag the Milestone so that the new Notes that have been added will save? Edit: sorry, it's hard to paste in all of the code because there's so many parts, but here goes: Models class Project < ActiveRecord::Base has_many :notes, :dependent => :destroy has_many :milestones, :dependent => :destroy accepts_nested_attributes_for :milestones, :allow_destroy => true accepts_nested_attributes_for :notes, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Milestone < ActiveRecord::Base belongs_to :project has_many :notes, :dependent => :destroy accepts_nested_attributes_for :notes, :allow_destroy => true, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Note < ActiveRecord::Base belongs_to :milestone belongs_to :project scope :newest, lambda { |*args| order('created_at DESC').limit(*args.first || 3) } end I'm using an jQuery-based, unobtrusive version of Ryan Bates' combo helper/JS code to get this done. Application Helper def add_fields_for_association(f, association, partial) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(partial, :f => builder) end end I render the form for the association in a hidden div, and then use the following JavaScript to find it and add it as needed. JavaScript function addFields(link, association, content, func) { var newID = new Date().getTime(); var regexp = new RegExp("new_" + association, "g"); var form = content.replace(regexp, newID); var link = $(link).parent().next().before(form).prev(); if (func) { func.call(); } return link; } I'm guessing the only other relevant piece of code that I can think of would be the create method in the NotesController: def create respond_with(@note = @owner.notes.create(params[:note])) do |format| format.js { render :json => @owner.notes.newest(3).all.to_json } format.html { redirect_to((@milestone ? [@project, @milestone, @note] : [@project, @note]), :notice => 'Note was successfully created.') } end end The @owner ivar is created in the following before filter: def load_milestone @milestone = @project.milestones.find(params[:milestone_id]) if params[:milestone_id] end def determine_owner @owner = load_milestone @owner ||= @project end Thing is, all this seems to work fine, except when I'm adding new notes to existing milestones. The milestone has to be "touched" in order for new notes to save, or else Rails won't pay attention.
