  • Symfony file upload - "Array" stored in database instead of the actual filename

    - by Guillaume Flandre
    I'm using Symfony 1.4.4 and Doctrine and I need to upload an image on the server. I've done that hundreds of times without any problem but this time something weird happens : instead of the filename being stored in the database, I find the string "Array". Here's what I'm doing: In my Form: $this->useFields(array('filename')); $this->embedI18n(sfConfig::get('app_cultures')); $this->widgetSchema['filename'] = new sfWidgetFormInputFileEditable(array( 'file_src' => '/uploads/flash/'.$this->getObject()->getFilename(), 'is_image' => true, 'edit_mode' => !$this->isNew(), 'template' => '<div id="">%file%</div><div id=""><h3 class="">change picture</h3>%input%</div>', )); $this->setValidator['filename'] = new sfValidatorFile(array( 'mime_types' => 'web_images', 'path' => sfConfig::get('sf_upload_dir').'/flash', )); In my action: public function executeIndex( sfWebRequest $request ) { $this->flashContents = $this->page->getFlashContents(); $flash = new FlashContent(); $this->flashForm = new FlashContentForm($flash); $this->processFlashContentForm($request, $this->flashForm); } protected function processFlashContentForm($request, $form) { if ( $form->isSubmitted( $request ) ) { $form->bind( $request->getParameter( $form->getName() ), $request->getFiles( $form->getName() ) ); if ( $form->isValid() ) { $form->save(); $this->getUser()->setFlash( 'notice', $form->isNew() ? 'Added.' : 'Updated.' ); $this->redirect( '@home' ); } } } Before binding my parameters, everything's fine, $request->getFiles($form->getName()) returns my files. But afterwards, $form->getValue('filename') returns the string "Array". Did it happen to any of you guys or do you see anything wrong with my code? Edit: I added the fact that I'm embedding another form, which may be the problem (see Form code above).

  • LINQ-To-SQL and Mapping Table Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • Year split in Quarters using basic jQuery

    - by Alexander Corotchi
    Hi, I have a interesting question: I want to split the year into 4 quarters. What is the idea, A quarter can be different: The HTML Code: <div class="quarterBody"> <span>04-29-2010</span> <span>06-29-2010</span> <span>08-29-2010</span> </div> jQuery (javascript) is total wrong, I hope that w: $(document).ready(function(){ var quarter1 = to make interval (01-01-2010 to 03-31-2010); var quarter2 = to make interval (03-01-2010 to 06-31-2010); var quarter3 = to make interval (06-01-2010 to 09-31-2010); var quarter4 = to make interval (09-01-2010 to 12-31-2010); ... $(".quarterBody span").each(function(){ var date = Date.parse($(this).text()); //to apply some magic code $(this).addClass(quarterNumber); }); }); OUTPUT: <div class="quarterBody"> <span class="Quarter1">02-29-2010</span> <span class="Quarter2">04-29-2010</span> <span class="Quarter3">08-29-2010</span> ... </div> I know right now it is a stupid way, but I hope that somebody can help me, or suggest an idea how to do that in a better way!! Thanks!

  • JAVASCRIPT changing on click

    - by Webby
    Hello, Id like some help changing this javascript onclick event to just load the data on page the page load... Preferably not using the body on load tag... So obviously I'd pre set the var for term inside the script term rather than the excisting on click event.. Hope that made sense <p><a id="keywordlink" href="?term=wombats">Get keywords for wombats</a></p> <script type="text/javascript" src="keywords.js"></script> <script type="text/javascript"> var x = document.getElementById('keywordlink'); if(x){ x.onclick = function(){ var term = this.href.split('=')[1]; this.innerHTML += ' (loading...)'; KEYWORDS.get(term,seed); return false; } } function seed(o){ var div = document.createElement('div'); var head = document.createElement('h2'); head.innerHTML = 'Keywords for '+o.term; div.appendChild(head); var p = document.createElement('p'); p.innerHTML = o.toplist; div.appendChild(p); var head = document.createElement('h3'); head.innerHTML = 'Details:'; div.appendChild(head); var list = document.createElement('ol'); for(var i=0,j=o.keywords.length;i<j;i++){ var li = document.createElement('li'); li.innerHTML = o.keywords[i].term + '('+o.keywords[i].amount+')'; list.appendChild(li); } div.appendChild(list); x.parentNode.replaceChild(div,x); } </script>

  • event.target doesn't work

    - by rdesign
    Hey guys, I've wrote some jquery code with some draggable elements and one droparea. Unfortunately my droparea can't make a difference between various object. Here's my code. <script type="text/javascript"> $(function() { $("#droparea").droppable({ drop: function(event) { var $target = $(event.target); if($target.is("#flyer")) { alert("adasd"); } } }); }); </script> </head> <body> <div id="droparea"></div> <div class="polaroid" id="flyer"> <img src="images/muesliFlyer.png" alt="flyer" /> </div> Without the if it works. But then I can't get the dropped object. Any ideas why my target isn't recognized? thanks a lot.

  • Failure to register .dll with regsvr32 - only in Release build.

    - by Hendrik
    Hi, I'm having a weird problem when trying to register the .dll i created using regsvr32. During development everything went fine, the debug version registers and works fine. Now i wanted to create a Release version, but that Version does not register anymore. regsvr32 comes up with the following error: The module "mpegsplitter.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified procedure could not be found. Some research brought me to the dependency walker, which does tell me this Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module. It also does show a dependency on "crtdll.dll" that the debug version does not have (The function view shows soem functions that normally should be in ole32.dll), which is colored red'ish. So far so good, i guess its somehow related to what the dependency walker shows there. But where do i go from here? How do i fix it? Any help would be greatly appreciated, that has been keeping me busy for several hours already. Thanks!

  • Correct escaping of delimited identifers in SQL Server without using QUOTENAME

    - by Ross Bradbury
    Is there anything else that the code must do to sanitize identifiers (table, view, column) other than to wrap them in double quotation marks and "double up" and double quotation marks present in the identifier name? References would be appreciated. I have inherited a code base that has a custom object-relational mapping (ORM) system. SQL cannot be written in the application but the ORM must still eventually generate the SQL to send to the SQL Server. All identifiers are quoted with double quotation marks. string QuoteName(string identifier) { return "\" + identifier.Replace("\"", "\"\"") + "\""; } If I were building this dynamic SQL in SQL, I would use the built-in SQL Server QUOTENAME function: declare @identifier nvarchar(128); set @identifier = N'Client"; DROP TABLE [dbo].Client; --'; declare @delimitedIdentifier nvarchar(258); set @delimitedIdentifier = QUOTENAME(@identifier, '"'); print @delimitedIdentifier; -- "Client""; DROP TABLE [dbo].Client; --" I have not found any definitive documentation about how to escape quoted identifiers in SQL Server. I have found Delimited Identifiers (Database Engine) and I also saw this stackoverflow question about sanitizing. If it were to have to call the QUOTENAME function just to quote the identifiers that is a lot of traffic to SQL Server that should not be needed. The ORM seems to be pretty well thought out with regards to SQL Injection. It is in C# and predates the nHibernate port and Entity Framework etc. All user input is sent using ADO.NET SqlParameter objects, it is just the identifier names that I am concerned about in this question. This needs to work on SQL Server 2005 and 2008.

  • boost lambda::bind return type selection

  • Change NSTimer interval for repeating timer.

    - by user300713
    Hi, I am running a mainLoop in Cocoa using an NSTimer set up like this: mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/fps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; At Program startup I set the timeInterval to 0.0 so that the mainloop runs as fast as possible. Anyways, I would like to provide a function to set the framerate(and thus the time interval of the timer) to a specific value at runtime. Unfortunately as far as I know that means that I have to reinitialize the timer since Cocoa does not provide a function like "setTimerInterval" This is what I tried: - (void)setFrameRate:(float)aFps { NSLog(@"setFrameRate"); [mainLoopTimer invalidate]; mainLoopTimer = nil; mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/aFps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; } but this throws the following error and stops the mainloop: 2010-06-09 11:14:15.868 myTarget[7313:a0f] setFrameRate 2010-06-09 11:14:15.868 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40cd80 of class __NSCFDate autoreleased with no pool in place - just leaking 2010-06-09 11:14:15.869 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40e700 of class NSCFTimer autoreleased with no pool in place - just leaking 0.614628 I also tried to recreate the timer using the "retain" keyword, but that didn't change anything. Any ideas about how to dynamically change the interval of an NSTimer at runtime? Thanks!

  • Should the entity framework + self tracking entities be saving me time

    - by sipwiz
    I've been using the entity framework in combination with the self tracking entity code generation templates for my latest silverlight to WCF application. It's the first time I've used the entity framework in a real project and my hope was that I would save myself a lot of time and effort by being able to automatically update the whole data access layer of my project when my database schema changed. Happily I've found that to be the case, updating my database schema by adding a new table, changing column names, adding new columns etc. etc. can be propagated to my business object classes by using the update from database option on the entity framework model. Where I'm hurting is the CRUD operations within my WCF service in response to actions on my Silverlight client. I use the same self tracking entity framework business objects in my Silverlight app but I find I'm continually having to fight against problems such as foreign key associations not being handled correctly when updating an object or the change tracker getting confused about the state of an object at the Silverlight end and the data access operation within the WCF layer throwing a wobbly. It's got to a point where I have now spent more time dealing with this quirks than I have on my previous project where I used Linq-to-SQL as the starting point for rolling my own business objects. Is it just me being hopeless or is the self tracking entities approach something that should be avoided until it's more mature?

  • Alternative Python standard library reference

    - by Ender
    I love Python; I absolutely despise its official documentation. Tutorials do not count as library references, but that appears to be what they're attempting. What I really want is the ability to find a class in the standard library and view documentation for all of its properties and methods. Actionscript, MSDN, and Java all do this just fine (although each with their odd quirks). Where is this for python? For example, I wanted to sort a list. mylist.sort(). Awesome. But what if I wanted it sorted in descending order? Official documentation is not - much - help. Or what if I wanted to specify a key function? That's also supported: mylist.sort(key=lamba item: item.customVar)- but documented...where? I understand that Python's approach to OOP may not be equivalent to Java et. al. Maybe list isn't actually a class - maybe it's just a function that returns an iterable when the tachyon beams are set to glorious and the unboxed hyper enumeration is quantized, but...I don't care. I just want to know how to sort lists. (Apologies for the angst - too much caffeine today)

  • Call to CFC via Ajax-POST does not work

    - by Philipp
    We have the following problem: A CFC-method that is called from AJAX suddenly redirects the request to cfcexplorer instead of executing the request. The strange thing is, that the problem only occurs when we make the ajax call via "POST" method, like this: // This will return the HTTP Status header: // Location: http://url.to:80/CFIDE/componentutils/cfcexplorer.cfc?method=getcfcinhtml&name=web.ajax&path=/web/ajax.cfc $.post( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc POST return:" + res); } ); Making the same request as "GET" request works perfectly: // This will call the method "test" of web/ajax.cfc $.get( "http://url.to/ajax.cfc", {method: "test"}, function(res) { alert("ajax.cfc GET return:" + res); } ); This is the ajax.cfc file (dummy file): <cfcomponent> <cffunction name="test" access="remote" returntype="Any" returnformat="JSON"> <cfset j = {}> <cfset j.data = "this is the data"> <cfreturn serializeJson(j)> </cffunction> </cfcomponent> What really puzzles us is that the request did work in the past (we have a lot of code all making ajax calls via POST and CF-code that expects FORM-data to be present, so we cannot simply change the method to GET) Maybe there was some setting that has changed or similar...

  • Calculating odds distribution with 6-sided dice

    - by Stephen
    I'm trying to calculate the odds distribution of a changing number of 6-sided die rolls. For example, 3d6 ranges from 3 to 18 as follows: 3:1, 4:3, 5:6, 6:10, 7:15, 8:21, 9:25, 10:27, 11:27, 12:25, 13:21, 14:15, 15:10, 16:6, 17:3, 18:1 I wrote this php program to calculate it: function distributionCalc($numberDice,$sides=6) { for ( $i=0; $i<pow($sides,$numberDice); $i++) { $sum=0; for ($j=0; $j<$numberDice; $j++) { $sum+=(1+(floor($i/pow($sides,$j))) % $sides); } $distribution[$sum]++; } return $distribution; } The inner $j for-loop uses the magic of the floor and modulus functions to create a base-6 counting sequence with the number of digits being the number of dice, so 3d6 would count as: 111,112,113,114,115,116,121,122,123,124,125,126,131,etc. The function takes the sum of each, so it would read as: 3,4,5,6,7,8,4,5,6,7,8,9,5,etc. It plows through all 3^6 possible results and adds 1 to the corresponding slot in the $distribution array between 3 and 18. Pretty straightforward. However, it only works until about 8d6, afterward i get server time-outs because it's now doing billions of calculations. But I don't think it's necessary because die probability follows a sweet bell-curve distribution. I'm wondering if there's a way to skip the number crunching and go straight to the curve itself. Is there a way to do this, so, for example, with 80d6 (80-480)? Can the distribution be projected without doing 6^80 calculations? I'm not a professional coder and probability is still new to me, so thanks for all the help! Stephen

  • Yacc and Lex inclusion confusion

    - by thejohnmeister
    I am wondering how to correctly compile a program with a Makefile that has calls to yyparse in it? This is what I do: I have a Makefile that compiles all my regular files and they have no connections to y.tab.c or lex.yy.c (Am I supposed to have them?) I do this on top of my code: #include "y.tab.c" #include "lex.yy.c" #include "y.tab.h" This is what happens when I try to make the program: When I just type in "make", it gives me many warnings. Some of the examples are shown below. In function yywrap': /src/parser.y:12: multiple definition ofyywrap' server.o :/src/parser.y:12: first defined here utils.o: In function yyparse': /src/y.tab.c:1175: multiple definition ofyyparse' server.o:/src/y.tab.c:1175: first defined here utils.o I get many different errors referring to different yy_* files. I have compiled successfully with multiple calls to yyparse in the past, but this time seems to be different. It seems an awful lot like an inclusion problem somewhere but I can't tell what it is. All my header files have ifndef conditions, as well. Thanks for your help!

  • @OneToMany and composite primary keys?

    - by Kris Pruden
    Hi, I'm using Hibernate with annotations (in spring), and I have an object which has an ordered, many-to-one relationship which a child object which has a composite primary key, one component of which is a foreign key back to the id of the parent object. The structure looks something like this: +=============+ +================+ | ParentObj | | ObjectChild | +-------------+ 1 0..* +----------------+ | id (pk) |-----------------| parentId | | ... | | name | +=============+ | pos | | ... | +================+ I've tried a variety of combinations of annotations, none of which seem to work. This is the closest I've been able to come up with: @Entity public class ParentObject { @Column(nullable=false, updatable=false) private String id; @OneToMany(mappedBy="object", fetch=FetchType.EAGER) @IndexColumn(name = "pos", base=0) private List<ObjectChild> attrs; ... } @Entity public class ChildObject { @Embeddable public static class Pk implements Serializable { @Column(nullable=false, updatable=false) private String objectId; @Column(nullable=false, updatable=false) private String name; @Column(nullable=false, updatable=false) private int pos; ... } @EmbeddedId private Pk pk; @ManyToOne @JoinColumn(name="parentId") private ParentObject parent; ... } I arrived at this after a long bout of experimentation in which most of my other attempts yielded entities which hibernate couldn't even load for various reasons. The error I get when I try to read one of these objects (they seem to save OK), I get an error of this form: org.hibernate.exception.SQLGrammarException: could not initialize a collection: ... And the root cause is this: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'attrs0_.id' in 'field list' I'm sure I'm missing something simple, but the documentation is not clear on this matter, and I haven't been able to find any examples of this anywhere else. Thanks!

  • Probably an easy one - PHP/CodeIgniter 'Undefined Variable'

    - by Jack W-H
    Morning y'all This is probably an easy one but I barely got any sleep last night and am struggling to comprehend anything. I've got a CodeIgniter library I've made called Points.php. Here's the contents of Points: <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Points { function __construct() { $this->ci =& get_instance(); $this->ci->load->database(); } function getpoints($params) { echo $userid; } } /* End of file Points.php */ /* Location: ./application/libraries/Points.php */ ?> As you can see, I'm building it up slowly and it's being kept simple. In one of my views, I want it to display the number of 'points' (which for the time being is simply the third segment of the URI). I call it like this: <p>Points: <?php $params['user_id']=$this->uri->segment(3,1); echo $this->points->getpoints($params); ?></p> The warning I get back in the view is this: A PHP Error was encountered Severity: Notice Message: Undefined variable: userid Filename: libraries/Points.php Yes I know it's such a simple problem but I've tried lots of things. Some variations include echoing in Points.php $params['userid']; etc. But I don't see what I'm doing wrong? This is my first CodeIgniter class and I've fallen at the first step, haha...

  • Using hash tables in racket

    - by user2963128
    Im working on an Ngrams program and im having trouble filling out my hash table. i want to write out a recursive function that will take the words and add them to the hash table. The way its supposed to work is given the data set 1 2 3 4 5 6 7 the first entry in the hash table should have a key of [1 2] and the data should be 3. The second entry should be: [2 3] and its data should be 4 and continuing on until the end of the text file. we are given a predefined function called readword that will simply return 1 word from the text. But im not sure how to make these calls overlap each other. The calls would look something like this if the data was hard coded in. (hash-set! (list "1" "2") 3 (hash-set! (list "2" "3") 4 2 calls that ive tried look like this (hash-set! Ngram-table(list((word1) (word2)) readword in))) (hash-set! Ngram-table(append((cdr data) word1)) readword in) apparently the in after readword is supposed to tell the computer that this is and input instead of an output or something like that. How would I call this to make the data in the key of the hashtable overlap like this? And what would the recursive call look like? edit: also we are not allowed to use assigment statements in this program.

    I have one-to-one hibernate mapping between class Student and class Points: @Entity @Table(name = "Users") public class Student implements IUser { @Id @Column(name = "id") private int id; @Column(name = "name") private String name; @Column(name = "password") private String password; @OneToOne(fetch = FetchType.EAGER, mappedBy = "student") private Points points; @Column(name = "type") private int type = getType(); //gets and sets... @Entity @Table(name = "Points") public class Points { @GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "student")) @Id @GeneratedValue(generator = "generator") @Column(name = "id", unique = true, nullable = false) private int Id; @OneToOne @PrimaryKeyJoinColumn private Student student; //gets and sets And then i do: Student student = new Student(); student.setId(1); student.setName("Andrew"); student.setPassword("Password"); Points points = new Points(); points.setPoints(0.99); student.setPoints(points); points.setStudent(student); Session session = HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); session.save(student); session.getTransaction().commit(); And hibernate saves student in the table but not saves corresponding points. Is it OK? Should i save points separately?

  • JQuery-UI Drag, Drop and Re-Drag Clones on Re-Drag

    - by amarcy
    I am using the following code to extend the JQuery-UI demos included with the download. I am trying to set up a container that the user can drag items into and then move the items around within the container. I incorporated the answer from http://stackoverflow.com/questions/867469/jquery-draggable-clone which works with one problem. <script> $(document).ready(function() { $("#droppable").droppable({ accept: '.ui-widget-content', drop: function(event, ui) { if($(ui).parent(":not(:has(#id1))")){ $(this).append($(ui.helper).clone().attr("id", "id1")); } $("#id1").draggable({ containment: 'parent', }); } }); $(".ui-widget-content").draggable({helper: 'clone'}); }); </script> div class="demo"> <div id="draggable" class="ui-widget-content"> <p>Drag me around</p> </div> <div id="droppable" class="ui-widget-header"> <p>Drop here</p> </div> When an item is dropped onto the droppable container it can be dragged one time and when it is dropped after that drag it loses its dragging capability. How do I allow for the item to be dragged multiple times after it has been added to the droppable container?

  • problems with infinite loop

    - by Tom
    function addAds($n) { for ($i=0;$i<=$n;$i++) { while($row=mysql_fetch_array(mysql_query("SELECT * FROM users"))) { $aut[]=$row['name']; } $author=$aut[rand(0,mysql_num_rows(mysql_query("SELECT * FROM users")))]; $name="pavadinimas".rand(0,3600); $rnd=rand(0,1); if($rnd==0) { $type="siulo"; } else { $type="iesko"; } $text="tekstas".md5("tekstas".rand(0,8000)); $time=time()-rand(3600,86400); $catid=rand(1,9); switch ($catid) { case 1: $subid=rand(1,8); break; case 2: $subid=rand(9,16); break; case 3: $subid=rand(17,24); break; case 4: $subid=rand(25,32); break; case 5: $subid=rand(33,41); break; case 6: $subid=rand(42,49); break; case 7: $subid=rand(50,56); break; case 8: $subid=rand(57,64); break; case 9: $subid=rand(65,70); break; } mysql_query("INSERT INTO advert(author,name,type,text,time,catid,subid) VALUES('$author','$name','$type','$text','$time','$catid','$subid')") or die(mysql_error()); } echo "$n adverts successfully added."; } The problem with this function, is that it never loads. As I noticed, my while loop causes it. If i comment it, everything is ok. It has to get random user from my db and set it to variable $author.

  • is this valid json array using php

    - by Rich
    Hello, I need to convert some code done by someone else, to work in my mvc model It is using some functions like EOD that I don't understand. Does that still work in a class? Primarely, my question focusus on the json output. The old code does not use the php json_encode function, but outputs it directly like this ?> { "username": "<?php echo $_SESSION['username'];?>", "items": [ <?php echo $items;?> ] } <?php I would do it like this, but I need to be sure it's right for the items part header('Content-type: application/json'); $output = array("username"=> isset( $_SESSION['username'] ) ? $_SESSION['username'] : "?", "items"=>$items ); $this->content = json_encode($output); This is some background on how the $items is made. An item is stored like this: $_SESSION['chatHistory'][$_POST['to']] .= <<<EOD { "s": "1", "f": "{$to}", "m": "{$messagesan}" }, EOD; and it is put in the $items variable like this $items = ''; if ( !empty($_SESSION['openChatBoxes'] ) ) { foreach ( $_SESSION['openChatBoxes'] as $chatbox => $void ) { $items .= $this->chatBoxSession($chatbox); } } //The chatBoxSession() function takes an item from the $_SESSION['chatHistory'] array and returns it. I hope this was somewhat clear enough? The php manual warns that in some cases you don't get an array output, instead you get an object. So, with the EOD syntax, I am not really sure. It could save me some time if I know some things are doing what they supposed too, and giving the right output. thanks, Richard

  • How to cache L2E entity without attach/detach?

    - by Eran Betzalel
    The following code will select a key/value table in the DB and will save the result to the cache: using (var db = new TestEntities()) { if(Cache["locName_" + inventoryLocationName] != null) return Cache["locName_" + inventoryLocationName]; var location = db.InventoryLocationsSet.FirstOrDefault( i => i.InventoryLocationName.Equals( inventoryLocationName, StringComparison.CurrentCultureIgnoreCase)); db.Detach(location); // ???? Cache["locName_" + inventoryLocationName] = location; return location; } But it doesn't work well when I'm trying to use the cached object. Of course, the problem is the different ObjectContext, so I use Attach/Detach and then the problem solves but with a codding horror price: db.Attach(locationFromCache); // ???? try { // Use location as foreign key db.SaveChanges(); } finally { db.Detach(locationFromCache); // ???? } So, how can I use cached objects without using attach/detach methods? What happens if more than one user will have to use this cached object? Should I put the whole thing in a CriticalSection?!
