  • How to display image in grails GSP?

    - by Walter
    I'm still learning Grails and seem to have hit a stumbling block. Here are the 2 domain classes: class Photo { byte[] file static belongsTo = Profile } class Profile { String fullName Set photos static hasMany = [photos:Photo] } The relevant controller snippet: class PhotoController { ..... def viewImage = { def photo = Photo.get( params.id ) byte[] image = photo.file response.outputStream << image } ...... } Finally the GSP snippet: <img class="Photo" src="${createLink(controller:'photo', action:'viewImage', id:'profileInstance.photos.get(1).id')}" /> Now how do I access the photo so that it will be shown on the GSP? I'm pretty sure that profileInstance.photos.get(1).id is not correct. Thanks!!

  • ASP.NET MVC Concurrency with RowVersion in Edit Action

    - by Jorin
    I'm wanting to do a simple edit form for our Issue Tracking app. For simplicity, the HttpGet Edit action looks something like this: // Issues/Edit/12 public ActionResult Edit(int id) { var thisIssue = edmx.Issues.First(i => i.IssueID == id); return View(thisIssue); } and then the HttpPost action looks something like this: [HttpPost] public ActionResult Edit(int id, FormCollection form) { // this is the dumb part where I grab the object before I update it. // concurrency is sidestepped here. var thisIssue = edmx.Issues.Single(c => c.IssueID == id); TryUpdateModel(thisIssue); if (ModelState.IsValid) { edmx.SaveChanges(); TempData["message"] = string.Format("Issue #{0} successfully modified.", id); return RedirectToAction("Index"); } return View(thisIssue); } Which works wonderfully. However, the concurrency check doesn't work because in the Post, I'm re-retreiving the current entity right before I attempt to update it. However, with EF, I don't know how to use the fanciness of SaveChanges() but attach my thisIssue to the context. I tried to call edmx.Issues.Attach(thisIssue) but I get The object cannot be attached because it is already in the object context. An object can only be reattached when it is in an unchanged state. How do I handle concurrency in MVC with EF and/or how do I properly Attach my edited object to the context? Thanks in advance

  • can't get jquery livequery to with an update panel

    - by Jeremy
    I have some basic html inside an asp.net update panel. Using livequery, I set up autocomplete, blur and keydown events so that they all continue to be wired up after the update panel does a partial page load. When the page initially loads, all the events work fine but after the update panel does a partial page reload, none of the events wired up with livequery continue to work. Are there known issues with livequery and update panels? Html: <asp:UpdatePanel ID="upData" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:DataList ID="dlData" runat="server" DataSource='<%# this.Data %>' DataKeyField="ID"> <ItemTemplate> <table> <tr> <th class="required">Location</th> <td><asp:TextBox ID="txtFromLocation" MaxLength="10" CssClass="searchlocation fromlocation required" runat="server" Text='<%# Eval("FromLocation")%>'/><asp:RequiredFieldValidator ID="rvalFromLocation" runat="server" ControlToValidate="txtFromLocation" ValidationGroup="leg">*</asp:RequiredFieldValidator></td> </tr> </table> </ItemTemplate> </asp:DataList> </ContentTemplate> </asp:UpdatePanel> And then I have my javascript. Normally it has a bunch of other code, but I can reduce it down to this and still have the problem: $(document).ready(function() { $(".searchlocation").livequery(function() { $(this).keydown(function(event) {alert('test');}); }); });

  • jQuery Ajax (beforeSend and complete) working properly on FireFox but not on IE8 and Chrome

    - by Farhan Zia
    I am using jQuery ajax version 1.4.1 in my MVC application (though the issue I am discussing was same with the old jQuery version 3.2.1) as well, to check during customer registration if the username is already registered. As the user clicks on the "Check Availibility" button, I am showing a busy image in place of the check button (actually hiding the check button and showing the image) while checking the availibility on the server and then displaying a message. It is a Sync call (async: false) and I used beforeSend: and complete: to show and hide the busy image and the check button. This thing is working well on Firefox but in IE 8 and Chrome, neither the busy image appear nor the check button hides rather the check button remained pressed as the whole thing has hanged. The available and not available messages appear correctly though. Below is the code: HTML in a User Control (ascx): (i have replaced the angular braces with square below) [div id="available"]This Username is Available [div id="not_available"]This Username is not available [input id="txtUsername" name="txtUsername" type="text" size="50" /]  [button id="check" name="check" type="button"]Check Availability[/button] [img id="busy" src="/Content/Images/busy.gif" /] On the top of this user control, I am linking an external javascript file that has the following code: $(document).ready(function() { $('img#busy').hide(); $('div#available').hide(); $('div#not_available').hide(); $("button#check").click(function() { var available = checkUsername($("input#txtUsername").val()); if (available == "1") { $("div#available").show(); $("div#not_available").hide(); } else { $("div#available").hide(); $("div#not_available").show(); } }); }); function checkUsername(username) { $.ajax({ type: "POST", url: "/SomeController/SomeAction", data: { "id": username }, timeout: 3000, async: false, beforeSend: function() { $("button#check").hide(); $("img#busy").show(); }, complete: function() { $("button#check").show(); $("img#busy").hide(); }, cache: false, success: function(result) { return result; }, error: function(error) { $("img#busy").hide(); $("button#check").show(); alert("Some problems have occured. Please try again later: " + error); } }); }

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • ASP.NET required field validator firing on focus in Firefox

    - by ren33
    I have 2 asp.net textboxes in an update panel. Both textbox controls have some javascript attached to autotab to the next field and to allow only numeric input. When I enter some data into the first field and press enter, focus shifts to the next field and the requiredfieldvalidator of the second field displays its "* required" error message, even though I've just entered the field. This is only happening in Firefox. How can I prevent the validator from firing when I first enter the textbox? edit Here's the code: <asp:TextBox ID="add_ISBN" runat="server" Columns="14" MaxLength="17" CssClass="focus" /> <asp:TextBox ID="add_Qty" runat="server" Columns="4" MaxLength="4" /> <asp:RequiredFieldValidator ID="rfvQty" ControlToValidate="add_Qty" ErrorMessage="* required" ForeColor="Red" Display="Dynamic" EnableClientScript="true" ValidationGroup="Add" runat="server" /> In the codebehind: add_ISBN.Attributes.Add("onkeydown", "return isbnCheck(event, '" & add_Qty.ClientID & "')") And the javascript: function isbnCheck(e, id) { e = e || window.event; var key = e.which || e.keyCode if (validIsbnChars.indexOf(parseInt(key, 10)) >= 0) { return true; } else { if (key == 13) { var nextfield = document.getElementById(id); if (nextfield) nextfield.focus(); return false; } if (e.preventDefault) e.preventDefault(); e.returnValue = false; return false; } } The javascript allows only a valid subset of characters, and if the user presses enter, sets focus to the next field.

    - by Ubaid
    i just loved the fullcalendar and wanted to implement it in a small application, everythin worked OK. i am able to get the events from my database through json to the front end. but all events are being listed as "ALL-DAY" events itself. not able to figure out why.. here is the screenshot for the same. any ideas what is going wrong..? i am using asp.net and c#. i have already tried sending the start and end dates in the ToString(), ToShortDateString(), ToString("s"), ToLongDateString(), ToUniversalTime(). nothing seems to working for me at the moment. i tried hard coding and sendin the data too. sample json of my data [{ "id": "2", "title": "Event2", "start": "1274171700", "end": "1274175600" }, { "id": "1", "title": "Event1", "start": "5/18/2010 16:30:00", "end": "5/18/2010 19:30:00" }, { "id": "3", "title": "Event3", "start": "5/18/2010 2:05:00 PM", "end": "5/18/2010 3:10:00 PM" }, { "id": "4", "title": "Event4", "start": "5/18/2010", "end": "5/18/2010" }, { "id": "5", "title": "Event5", "start": "2010-05-18T14:05:00", "end": "2010-05-18T15:10:00" }] all data above has different formats of dates, and at the moment nothing seems to be working. fullcalender accepts the day part fine, but not the time part. not sure why. can anybody help?

  • Does subTable support reRender?

    - by Tom
    Here is a minimal rich:dataTable with an a4j:commandLink inside. When clicked it sends an AJAX request to my bean and reRenders the dataTable. <rich:dataTable id="dataTable" value="#{carManager.all}" var="item"> <rich:column> <f:facet name="header">name</f:facet> <h:outputText value="#{item.name}" /> </rich:column> <rich:column> <f:facet name="header">action</f:facet> <a4j:commandLink reRender="dataTable" value="Delete" action="#{carForm.delete}"> <f:setPropertyActionListener value="#{item.id}" target="#{carForm.id}" /> <f:param name="from" value="list" /> </a4j:commandLink> </rich:column> </rich:dataTable> The exmaple obove works fine so far. But when I add a rich:subTable to the table, reRendering fails... <rich:dataTable id="dataTable" value="#{garageManager.all}" var="garage"> <f:facet name="header"> <rich:columnGroup> <rich:column>name</rich:column> <rich:column>action</rich:column> </rich:columnGroup> </f:facet> <rich:column colspan="2"> <h:outputText value="#{garage.name}" /> </rich:column> <rich:subTable value="#{garage.cars}" var="car"> <rich:column><h:ouputText value="#{car.name}" /></rich:column> <rich:column> <a4j:commandLink reRender="dataTable" value="Delete" action="#{carForm.delete}"> <f:setPropertyActionListener value="#{item.id}" target="#{carForm.id}" /> <f:param name="from" value="list" /> </a4j:commandLink> </rich:column> </rich:column> </rich:dataTable> Now the rich:dataTable is not rerendered but the item gets deleted since the item does not show up after a complete page refresh. Does subTable support reRender the way i'd like to use it here? Tanks Tom

    I'm trying to generate my Entity class using javassist. Everything went well until I added the GeneratedValue annotation to the Id field. The @Id annotation works fine but when I add @GeneeratedValue I get an exception.

When I use eclipse debugger to watch variable values, I get get this com.sun.jdi.InvocationException occurred invoking method. instead of the annotation value. but for Id annotation it shows a javassist annotation object. I'm new to javassist. Can anyone help me?

  • Android : ugly TABS in 2.0 vs 1.5 ... why ? where are my rounded corners TABS ?

    - by Hubert
    I simply use the tabwidget : mTabHost = getTabHost(); mTabHost.addTab(mTabHost.newTabSpec("tab_1").setIndicator(getString(R.string.day0)).setContent(R.id.tab1_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_2").setIndicator(getString(R.string.day1)).setContent(R.id.tab2_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_3").setIndicator(getString(R.string.day2)).setContent(R.id.tab3_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_4").setIndicator(getString(R.string.day3)).setContent(R.id.tab4_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_5").setIndicator(getString(R.string.about)).setContent(R.id.tab5_content)); mTabHost.setCurrentTab(0); Why are my tabs so uggly in 2.0 (no more rounded corners as in 1.5/1.6) ? ugly tabs here = this was better What should I do now to show "rounded corners" TABS to Nexus One (for exemple) users ;-) ? Is it because of the following manifest lines : <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> I have to keep android:anyDensity="true" otherwise I've got a problem with re-sizing of the menus described here As a separate question, my users can change the Locale within my app itself, I then "redraw" the menus using onPrepareOptionsMenu (Menu menu) to refresh the strings within the menu with the new language choosen by the user. Is there an equivalent for TABS (I have local strings within the Title of the TABS) or do I have to delete all the tabs and re-create them from scratch ? Txs in advance for your help. Hub

  • DDD principlers and ASP.NET MVC project design

    - by kaivalya
    Two part questions I have a product aggregate that has; Prices PackagingOptions ProductDescriptions ProductImages etc I have modeled one product repository and did not create individual repositories for any of the child classes. All db operations are handled through product repository. Am I understanding the DDD concept correctly so far? Sometimes the question comes to my mind that having a repository for lets say packaging options could make my life easier by directly fetching a the packaging option from the DB by using its ID instead of asking the product repository to find it in its PackagingOptions collection and give it to me.. Second part is managing the edit create operations using ASP.MVC frame work I am currently trying to manage all add edit remove of these child collections of product through product controller(sound right?). One challenge I am now facing is; If I edit a specific packaging option of product through mydomain/product/editpackagingoption/10 I have access to the id of the packaging option But I don't have the ID of the product it self and this forces me to write a query to first find the product that has this specific packaging option then edit that product and the revelant packaging option. I can do this as all packaging option have their unique ID but this would fail if I have collections that don't have unique ID. That feels very wrong.. The next option I thought of is sending both the product and packaging option IDs on the url like; mydomain/product/editpackagingoption/3/10 But I am not sure if that is a good design either. So I am at a point that I am a bit confused. might be having fundamental misunderstandings around all of this... I would appreciate if you bear with the long question and help me put this together. thanks!

  • SQL 2005 indexed queries slower than unindexed queries

    - by uos??
    Adding a seemingly perfectly index is having an unexpectedly adverse affect on a query performance... -- [Data] has a predictable structure and a simple clustered index of the primary key: ALTER TABLE [dbo].[Data] ADD PRIMARY KEY CLUSTERED ( [ID] ) -- My query, joins on itself looking for a certain kind of "overlapping" records SELECT DISTINCT [Data].ID AS [ID] FROM dbo.[Data] AS [Data] JOIN dbo.[Data] AS [Compared] ON [Data].[A] = [Compared].[A] AND [Data].[B] = [Compared].[B] AND [Data].[C] = [Compared].[C] AND ([Data].[D] = [Compared].[D] OR [Data].[E] = [Compared].[E]) AND [Data].[F] <> [Compared].[F] WHERE 1=1 AND [Data].[A] = @A AND @CS <= [Data].[C] AND [Data].[C] < @CE -- Between a range [Data] has about a quarter-million records so far, 10% to 50% of the data satisfies the where clause depending on @A, @CS, and @CE. As is, the query takes 1 second to return about 300 rows when querying 10%, and 30 seconds to return 3000 rows when querying 50% of the data. Curiously, the estimated/actual execution plan indicates two parallel Clustered Index Scans, but the clustered index is only of the ID, which isn't part of the conditions of the query, only the output. ?? If I add this hand-crafted [IDX_A_B_C_D_E_F] index which I fully expected to improve performance, the query slows down by a factor of 8 (8 seconds for 10% & 4 minutes for 50%). The estimated/actual execution plans show an Index Seek, which seems like the right thing to be doing, but why so slow?? CREATE UNIQUE INDEX [IDX_A_B_C_D_E_F] ON [dbo].[Data] ([A], [B], [C], [D], [E], [F]) INCLUDE ([ID], [X], [Y], [Z]); The Data Engine Tuning wizard suggests a similar index with no noticeable difference in performance from this one. Moving AND [Data].[F] <> [Compared].[F] from the join condition to the where clause makes no difference in performance. I need these and other indexes for other queries. I'm sure I could hint that the query should refer to the Clustered Index, since that's currently winning - but we all know it is not as optimized as it could be, and without a proper index, I can expect the performance will get much worse with additional data. What gives?

  • complex sql which runs extremely slow when the query has order by clause

    - by basit.
    I have following complex query which I need to use. When I run it, it takes 30 to 40 seconds. But if I remove the order by clause, it takes 0.0317 sec to return the result, which is really fast compare to 30 sec or 40. select DISTINCT media.* , username from album as album , album_permission as permission , user as user, media as media where ((media.album_id = album.album_id and album.private = 'yes' and album.album_id = permission.album_id and (permission.email = '' or permission.user_id = '') ) or (media.album_id = album.album_id and album.private = 'no' ) or media.album_id = '0' ) and media.user_id = user.user_id and media.media_type = 'video' order by media.id DESC LIMIT 0,20 The id on order by is primary key which is indexed too. So I don't know what is the problem. I also have album and album permission table, just to check if media is public or private, if private then check if user has permission or not. I was thinking maybe that is causing the issue. What if I did this in sub query, would that work better? Also can someone help me write that sub query, if that is the solution? If you can't help write it, just at least tell me. I'm really going crazy with this issue.. SOLUTION MAYBE Yes, I think sub-query would be best solution for this, because the following query runs at 0.0022 seconds. But I'm not sure if validation of an album would be accurate or not, please check. select media.*, username from media as media , user as user where media.user_id = user.user_id and media.media_type = 'video' and media.id in (select media2.id from media as media2 , album as album , album_permission as permission where ((media2.album_id = album.album_id and album.private = 'yes' and album.album_id = permission.album_id and (permission.email = '' or permission.user_id = '')) or (media.album_id = album.album_id and album.private = 'no' ) or media.album_id = '0' ) and media.album_id = media2.album_id ) order by media.id DESC LIMIT 0,20

  • RESTful idempotence

    - by DutrowLLC
    I'm designing a RESTful web service utilizing ROA(Resource oriented architecture). I'm trying to work out an efficient way to guarantee idempotence for PUT requests that create new resources in cases that the server designates the resource key. From my understanding, the traditional approach is to create a type of transaction resource such as /CREATE_PERSON. The the client-server interaction for creating a new person resource would be in two parts: Step 1: Get unique transaction id for creating the new PERSON resource::: **Client request:** GET /CREATE_PERSON **Server response:** 200 OK transaction-id:"as8yfasiob" Step 2: Create the new person resource in a request guaranteed to be unique by using the transaction id::: **Client request** PUT /CREATE_PERSON/{transaction_id} first_name="Big bubba" **Server response** 201 Created // (If the request is a duplicate, it would send this PersonKey="398u4nsdf" // same response without creating a new resource. It // would perhaps send an error response if the was used // on a transaction id non-duplicate request, but I have // control over the client, so I can guarantee that this // won't happen) The problem that I see with this approach is that it requires sending two requests to the server in order to do to single operation of creating a new PERSON resource. This creates a performance issues increasing the chance that the user will be waiting around for the client to complete their request. I've been trying to hash out ideas for eliminating the first step such as pre-sending transaction-id's with each request, but most of my ideas have other issues or involve sacrificing the statelessness of the application. Is there a way to do this?

  • parse Linq To Xml with attribute nodes

    - by Manoj
    I am having xml with following structure <ruleDefinition appId="3" customerId = "acf"> <node alias="element1" id="1" name="department"> <node alias="element2" id="101" name="mike" /> <node alias="element2" id="102" name="ricky" /> <node alias="element2" id="103" name="jim" /> </node> </ruleDefinition> Here nodes are differentiated using alias and not with node tag. As you can see top level node element1 has same node name "node" as element2. I want to parse this XML based on attribute alias. What should be the Linq-To-Xml code (using C#)to acheive this?

  • How to handle EntityExistsException properly?

    - by Ivan Yatskevich
    I have two entities: Question and FavoritesCounter. FavoritesCounter should be created when the question is added to favorites for the first time. Consider a use case when two users tries to add a question to favorites simultaneously - this will cause EntityExistsException when entityManager.persist(counter) is called for the second user. But the code below doesn't work, because when EntityExistsException is thrown, container marks transaction as rollback only and attempt to return getFavoritesCounter(question) fails with javax.resource.ResourceException: Transaction is not active @Stateless public class FavoritesServiceBean implements FavoritesService { ... public void addToFavorites(Question question) { FavoritesCounter counter = getCounter(question); if (counter == null) { counter = createCounter(question); } //increase counter } private FavoritesCounter createCounter(Question question) { try { FavoritesCounter counter = new FavoritesCounter(); counter.setQuestion(question); entityManager.persist(counter); entityManager.flush(); return counter; } catch (EntityExistsException e) { return getFavoritesCounter(question); } } private FavoritesCounter getFavoritesCounter(Question question) { Query counterQuery = entityManager.createQery("SELECT counter FROM FavoritesCounter counter WHERE counter.question = :question"); counterQuery.setParameter("question", question); List<FavoritesCounter> result = counterQuery.getResultList(); if (result.isEmpty()) return null; return result.get(0); } } Question @Entity public class Question implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //getter and setter for id } FavoritesCounter @Entity public class FavoritesCounter implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @OneToOne @Column(unique = true) private Question question; //getter and setter } What is the best way to handle such a situation - return already created entity after EntityExistsException?
