  • JPA2 Criteria API creates invalid SQL when using groupBy

    - by Stephan
    JPA2 with the Criteria API seems to generate invalid SQL for PostgreSQL. For this code: Root<DBObjectAccessCounter> from = query.from(DBObjectAccessCounter.class); Path<DBObject> object = from.get(DBObjectAccessCounter_.object); Expression<Long> sum = builder.sumAsLong(from.get(DBObjectAccessCounter_.count)); query.multiselect(object, sum).groupBy(object); I get the following exception: ERROR: column "dbobject1_.id" must appear in the GROUP BY clause or be used in an aggregate function The generated SQL is: select dbobjectac0_.object_id as col_0_0_, sum(dbobjectac0_.count) as col_1_0_, dbobject1_.id as id1001_, dbobject1_.name as name1013_, dbobject1_.lastChanged as lastChan2_1013_, dbobject1_.type_id as type3_1013_ from DBObjectAccessCounter dbobjectac0_ inner join DBObject dbobject1_ on dbobjectac0_.object_id=dbobject1_.id group by dbobjectac0_.object_id Obviously, the first item of the select statement (dbobjectac0_.object_id) does not match the group by clause. Simplified example It does not even work for this simple example: Root<DBObjectAccessCounter> from = query.from(DBObjectAccessCounter.class); Path<DBObject> object = from.get(DBObjectAccessCounter_.object); query.select(object).groupBy(object); which returns select dbobject1_.id as id924_, dbobject1_.name as name933_, dbobject1_.lastChanged as lastChan2_933_, dbobject1_.type_id as type3_933_ from DBObjectAccessCounter dbobjectac0_ inner join DBObject dbobject1_ on dbobjectac0_.object_id=dbobject1_.id group by dbobjectac0_.object_id Does anyone know how to fix this?

  • Velocity framework servlet

    - by GustlyWind
    I have a module written in servlets and needs to be recently moved to velocity framework So in the process I am rewriting the web.xml to create velocity servlet object whcih calls our original servlet . Now if this has to be moved to <servlet> <servlet-name>VeloServlet</servlet-name> <servlet-class>org.apache.velocity.tools.view.servlet.VelocityViewServlet</servlet-class> </servlet> How can we acheive this and what are all changes need to use the existing servlet as it is. My Existing servlet looks like <servlet-name>DataBridgeServlet</servlet-name> <servlet-class>com.jda.pwm.databridge.framework.common.DataBridgeServlet</servlet-class> <init-param> <param-name>jda.databridge.config.path</param-name> <param-value>d:/usr/databridge/conf</param-value> </init-param> This is loaded using the url http://localhost:8080/databridge/databridgeservlet So in the newer case how velocity servlet calls this servlet

  • How do I so a select input for a STI column in a Rails model?

    - by James A. Rosen
    I have a model with single-table inheritance on the type column: class Pet < ActiveRecord::Base TYPES = [Dog, Cat, Hamster] validates_presence_of :name end I want to offer a <select> dropdown on the new and edit pages: <% form_for @model do |f| %> <%= f.label :name %> <%= f.text_input :name %> <%= f.label :type %> <%= f.select :type, Pet::TYPES.map { |t| [t.human_name, t.to_s] } %> <% end %> That gives me the following error: ActionView::TemplateError (wrong argument type String (expected Module)) I read a suggestion to use an alias for the field #type since Ruby considers that a reserved word that's the same as #class. I tried both class Pet < ActiveRecord::Base ... alias_attribute :klass, :type end and class Pet < ActiveRecord::Base ... def klass self.type end def klass=(k) self.type = k end end Neither worked. Any suggestions? Oddly, it works fine on my machine (MRI 1.8.6 on RVM), but fails on the staging server (MRI 1.8.7 not on RVM).

  • Problem with adding and removing classes with jQuery when hovering over a list item.

    - by Andrew
    I want to add a class to a list item when I hover over it, and then remove it and add it to a different list item if a different list item is hovered over. Here's what I tried: jQuery - $(document).ready(function() { $("#results").text("Tournaments"); $("#Tournaments").addClass("box-active"); $("#box ul li").hover(function() { var show = $(this).attr('id'); $("#results").text(show); $("#box ul li").each(function() { $(this).removeClass("box-active"); }); $("#box ul li#" + show).addClass("box-active"); }); }); HTML - <div id="box"> <ul> <li id="Tournaments">Tournaments</li> <li id="Join">Join</li> <li id="Forums">Forums</li> <li id="GameBattles">GameBattles</li> <li id="Practice">Practice</li> </ul> <p>Hovering over: <span id="results"></span></p> </div> When I hover over an item, it changes the class, but if I hover over I different one it removes the class over the item I first hovered over, but doesn't add the class to the new item I'm hovering over. Not sure why, and any help would be appreciated.

  • [Java] Nested methods vs "piped" methods, which is better?

    - by Michael Mao
    Hi: Since uni, I've programming in Java for 3 years, although I am not fully dedicated to this language, I have spent quite some time in it, nevertheless. I understand both ways, just curious which style do you prefer. public class Test{ public static void main(String[] args) { System.out.println(getAgent().getAgentName()); } private static Agent getAgent() { return new Agent(); }} class Agent{ private String getAgentName() { return "John Smith"; }} I am pretty happy with nested method calls such like the following public class Test{ public static void main(String[] args) { getAgentName(getAgent()); } private static void getAgentName(Agent agent) { System.out.println(agent.getName()); } private static Agent getAgent() { return new Agent(); }} class Agent { public String getName(){ return "John Smith"; }} They have identical output I saw "John Smith" twice. I wonder, if one way of doing this has better performance or other advantages over the other. Personally I prefer the latter, since for nested methods I can certainly tell which starts first, and which is after. The above code is but a sample, The code that I am working with now is much more complicated, a bit like a maze... So switching between the two styles often blows my head in no time.

  • belongs_to with multiple models

    - by julie p
    Hi there! I am a Rails noob and have a question. I have a feed aggregator that is organized by this general concept: Feed Category (books, electronics, etc) Feed Site Section (home page, books page, etc) Feed (the feed itself) Feed Entry So: class Category < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 validates_presence_of :name attr_accessible :name, :id end class Section < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 attr_accessible :name, :id end class Feed < ActiveRecord::Base belongs_to :categories belongs_to :sections has_many :feed_entries validates_presence_of :name, :feed_url attr_accessible :name, :feed_url, :category_id, :section_id end class FeedEntry < ActiveRecord::Base belongs_to :feed belongs_to :category belongs_to :section validates_presence_of :title, :url end Make sense? Now, in my index page, I want to basically say... If you are in the Category Books, on the Home Page Section, give me the feed entries grouped by Feed... In my controller: def index @section = Section.find_by_name("Home Page") @books = Category.find_by_name("Books") end In my view: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds} -%> This partial will spit out the markup for each feed entry in the @books collection of Feeds. Now what I need to do is somehow combine the @books with the @section... I tried this: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds(:section_id => @section.id)} -%> But it isn't limiting by the section ID. I've confirmed the section ID by using the same code in the console... Make sense? Any advice? Thanks!

  • Invalid method declaration, return type required

    - by Brett Steen
    I am getting an error at public Rectangle(double width, double height){ saying that it's an invalid method declaration, return type required. I'm not sure how to fix it. These are also my instructions for my assignment: Write a super class encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length. It has two methods that calculate and return its area and volume. `public class Rectangle1 { private double width; private double height; public Rectangle1(){ } public Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth(){ return width; } public void setWidth(double width) { this.width = width; } public double getHeight(){ return height; } public void setHeight(double height){ this.height = height; } public double getArea(){ return width * height; } public double getPerimeter(){ return 2 * (width + height); } } public class TestRectangle { public static void main(String[] args) { Rectangle1 rectangle = new Rectangle1(2,4); System.out.println("\nA rectangle " + rectangle.toString()); System.out.println("The area is " + rectangle.getArea()); System.out.println("The perimeter is " + rectangle.getPerimeter()); } }`

  • NHibernate stored procedure problem

    - by Calvin
    I'm having a hard time trying to get my stored procedure works with NHibernate. The data returned from the SP does not correspond to any database table. This is my mapping file: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DomainModel" namespace="DomainModel.Entities"> <sql-query name="DoSomething"> <return class="SomeClass"> <return-property name="ID" column="ID"/> </return> exec [dbo].[sp_doSomething] </sql-query> </hibernate-mapping> Here is my domain class: namespace DomainModel.Entities { public class SomeClass { public SomeClass() { } public virtual Guid ID { get; set; } } } When I run the code, it fails with Exception Details: NHibernate.HibernateException: Errors in named queries: {DoSomething} at line 80 Line 78: config.Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "NHibernate.config")); Line 79: Line 80: g_sessionFactory = config.BuildSessionFactory(); When I debug into NHibernate code, it seems that SomeClass is not added to the persister dictionary because there isn't a class mapping (only sql-query) defined in hbm.xml. And later on in CheckNamedQueries function, it is not able to find the persistor for SomeClass. I've checked all the obvious things (e.g. make hbm as an embedded resource) and my code isn't too much different from other samples I found on the web, but somehow I just can't get it working. Any idea how I can resolve this issue?

  • Cannot edit values of DataGridView bound to a BindingList

    - by m_oLogin
    Hello community, I have trouble editing a databound bindinglist. Let me illustrate it with the following: Say I have the Person class: public Class Person{ private string m_firstname; private string m_lastname; public string FirstName{get;set;} public string LastName{get;set;} public Person{ ... } } I then have a containing class called Population: public class Population{ private BindingList<Person> m_lstPerson = new BindingList<Person>(); private string m_countryName; public BindingList<Person> ListPerson{get; set;} public string CountryName { get; set; } } I then have on one form a first datagridview with DataSource = m_lstPopulation (BindingList). The binding works like a charm when working with the Population objects. When I double click, it opens up a dialog form showing the object details. One tab in the details holds a datagridview bound to that population's ListPerson. The second datagridview displays fine. However, I cannot edit or add cells in this datagridview. None of the columns is set to read-only. In fact, both datagridview have just about the same parameters. What am I missing? It seems that a lock has been placed on the Population object so that its inner fields cannot be edited... Please advise. Thanks.

  • Absolutely positioned div on right causing scrollbar when the left doesn't

    - by Michael Snyder
    I'm trying to "flank" a centered div with some design elements that are absolutely positioned outside the main div's width. I'm getting a scroll bar due to the element on the right, but not the element on the left (IE6/7/8, Chrome, Firefox). How can I get rid of that horizontal scrollbar? <html> <head> <style type="text/css"> html, body { height: 100%; width: 100%; margin: 0; } body { text-align: center; } .wrapper { margin: 0 auto; position: relative; width: 960px; z-index: 0; } .main { background: #900; height: 700px; } .right, .left { position: absolute; height: 100px; width: 100px; } .right { background: #090; top: 0px; left: 960px; z-index: 1; } .left { background: #009; top: 0px; left: -100px; z-index: 1; } </style> </head> <body> <div class="wrapper"> <div class="main"></div> <div class="left"></div> <div class="right"></div> </div> </body> </html>

  • FluentValidation + s#arp

    - by csetzkorn
    Hi, Did someone implement something like this: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ in s#arp? Thanks. Christian PS: Hi, I have made a start in using FluentValidation in S#arp. I have implemented a Validator factory: public class ResolveType { private static IWindsorContainer _windsorContainer; public static void Initialize(IWindsorContainer windsorContainer) { _windsorContainer = windsorContainer; } public static object Of(Type type) { return _windsorContainer.Resolve(type); } } public class CastleWindsorValidatorFactory : ValidatorFactoryBase { public override IValidator CreateInstance(Type validatorType) { return ResolveType.Of(validatorType) as IValidator; } } I think I will use services which can be used by the controllers etc.: public class UserValidator : AbstractValidator { private readonly IUserRepository UserRepository; public UserValidator(IUserRepository UserRepository) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; RuleFor(user => user.Email).NotEmpty(); RuleFor(user => user.FirstName).NotEmpty(); RuleFor(user => user.LastName).NotEmpty(); } } public interface IUserService { User CreateUser(User User); } public class UserService : IUserService { private readonly IUserRepository UserRepository; private readonly UserValidator UserValidator; public UserService ( IUserRepository UserRepository ) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; this.UserValidator = new UserValidator(UserRepository); } public User CreateUser(User User) { UserValidator.Validate(User); ... } } Instead of putting concrete validators in the service, I would like to use the above factory somehow. Where do I register it and how in s#arp (Global.asax)? I believe s#arp is geared towards the nhibernator validator. How do I deregister it? Thanks. Best wishes, Christian

  • How can I make this method more Scalalicious

    - by Neil Chambers
    I have a function that calculates the left and right node values for some collection of treeNodes given a simple node.id, node.parentId association. It's very simple and works well enough...but, well, I am wondering if there is a more idiomatic approach. Specifically is there a way to track the left/right values without using some externally tracked value but still keep the tasty recursion. /* * A tree node */ case class TreeNode(val id:String, val parentId: String){ var left: Int = 0 var right: Int = 0 } /* * a method to compute the left/right node values */ def walktree(node: TreeNode) = { /* * increment state for the inner function */ var c = 0 /* * A method to set the increment state */ def increment = { c+=1; c } // poo /* * the tasty inner method * treeNodes is a List[TreeNode] */ def walk(node: TreeNode): Unit = { node.left = increment /* * recurse on all direct descendants */ treeNodes filter( _.parentId == node.id) foreach (walk(_)) node.right = increment } walk(node) } walktree(someRootNode) Edit - The list of nodes is taken from a database. Pulling the nodes into a proper tree would take too much time. I am pulling a flat list into memory and all I have is an association via node id's as pertains to parents and children. Adding left/right node values allows me to get a snapshop of all children (and childrens children) with a single SQL query. The calculation needs to run very quickly in order to maintain data integrity should parent-child associations change (which they do very frequently). In addition to using the awesome Scala collections I've also boosted speed by using parallel processing for some pre/post filtering on the tree nodes. I wanted to find a more idiomatic way of tracking the left/right node values. After looking at the answers listed I have settled on this synthesised version: def walktree(node: TreeNode) = { def walk(node: TreeNode, counter: Int): Int = { node.left = counter node.right = treeNodes .filter( _.parentId == node.id) .foldLeft(counter+1) { (counter, curnode) => walk(curnode, counter) + 1 } node.right } walk(node,1) }

  • SQL Server search filter and order by performance issues

    - by John Leidegren
    We have a table value function that returns a list of people you may access, and we have a relation between a search and a person called search result. What we want to do is that wan't to select all people from the search and present them. The query looks like this SELECT qm.PersonID, p.FullName FROM QueryMembership qm INNER JOIN dbo.GetPersonAccess(1) ON GetPersonAccess.PersonID = qm.PersonID INNER JOIN Person p ON p.PersonID = qm.PersonID WHERE qm.QueryID = 1234 There are only 25 rows with QueryID=1234 but there are almost 5 million rows total in the QueryMembership table. The person table has about 40K people in it. QueryID is not a PK, but it is an index. The query plan tells me 97% of the total cost is spent doing "Key Lookup" witht the seek predicate. QueryMembershipID = Scalar Operator (QueryMembership.QueryMembershipID as QM.QueryMembershipID) Why is the PK in there when it's not used in the query at all? and why is it taking so long time? The number of people total 25, with the index, this should be a table scan for all the QueryMembership rows that have QueryID=1234 and then a JOIN on the 25 people that exists in the table value function. Which btw only have to be evaluated once and completes in less than 1 second.

  • casting Collection<SomeClass> to Collection<SomeSuperClass>

    - by skrebbel
    Hi all, I'm sure this has been answered before, but I really cannot find it. I have a java class SomeClass and an abstract class SomeSuperClass. SomeClass extends SomeSuperClass. Another abstract method has a method that returns a Collection<SomeSuperClass>. In an implementation class, I have a Collection<SomeClass> myCollection I understand that I cannot just return myCollection, because Collection<SomeClass> does not inherit from Collection<SomeSuperClass>. Nevertheless, I know that everything in myCollection is a SomeSuperClass because after all, they're SomeClass objects which extend SomeSuperClass. How can I make this work? I.e. I want public class A { private Collection<SomeClass> myCollection; public Collection<SomeSuperClass> getCollection() { return myCollection; //compile error! } } The only way I've found is casting via a non-generic type and getting unchecked warnings and whatnot. There must be a more elegant way, though? I feel that also using Collections.checkedSet() and friends are not needed, since it is statically certain that the returned collection only contains SomeClass objects (this would not be the case when downcasting instead of upcasting, but that's not what I'm doing). What am I missing? Thanks!

  • Hibernate and parent/child relations

    - by Marco
    Hi to all, I'm using Hibernate in a Java application, and i feel that something could be done better for the management of parent/child relationships. I've a complex set of entities, that have some kind of relationships between them (one-to-many, many-to-many, one-to-one, both unidirectional and bidirectional). Every time an entity is saved and it has a parent, to estabilish the relationship the parent has to add the child to its collection (considering a one-to-may relationship). For example: Parent p = (Parent) session.load(Parent.class, pid); Child c = new Child(); c.setParent(p); p.getChildren().add(c); session.save(c); session.flush(); In the same way, if i remove a child then i have to explicitly remove it from the parent collection too. Child c = (Child) session.load(Child.class, cid); session.delete(c); Parent p = (Parent) session.load(Parent.class, pid); p.getChildren().remove(c); session.flush(); I was wondering if there are some best practices out there to do this jobs in a different way: when i save a child entity, automatically add it to the parent collection. If i remove a child, automatically update the parent collection by removing the child, etc. For example, Child c = new Child(); c.setParent(p); session.save(c); // Automatically update the parent collection session.flush(); or Child c = (Child) session.load(Child.class, cid); session.delete(c); // Automatically updates its parents (could be more than one) session.flush(); Anyway, it would not be difficult to implement this behaviour, but i was wondering if exist some standard tools or well known libraries that deals with this issue. And, if not, what are the reasons? Thanks

  • css block links and images

    - by Andrew Heath
    Given this html: <div class="nation"> <a href="library.php?type=nation&amp;id=America"> <div class="nation-image"> <img src="nations/America.png" alt="snip" /> </div> <h3>America</h3> </a> </div> the following CSS results in the entire <div class="nation"> becoming a clickable block link: .nation {float: left; text-align: center; width: 189px;} .nation img {width: 160px; margin: 10px 0 0 0; border: 1px solid #16160C;} but if I make the following single addition: .nation {float: left; text-align: center; width: 189px;} .nation-image {height: 138px;} .nation img {width: 160px; margin: 10px 0 0 0; border: 1px solid #16160C;} to specify the height of <div class="nation-image"> then the image (and only the image) is no longer a link, but the rest of the div (margin around it, h3 etc) remain a block link... /I am teh confussd :-?

  • UIViewTableCell didSelectRowAtIndexPath is calling but not pushing a view controller

    - by Kenneth
    Hi guys, so im having a UIViewController view with a UITableView. So the UIViewController class name is SelectionScreen. The UITableView class name is SelectionScreenTable. Picture: http://img717.imageshack.us/i/screenshot20100609atpm0.png/ I have declared a UITableView *selectionTable in SelectionScreen class and connected it to the xib file of the SelectionScreen what the problem is , is that when i click a row in the table,it stays selected as highlighted blue, it calls the didSelectRowAtIndexPath (checked with NSLog) but not pushing a new view which is called(GraphView). This is the code which i use to call the new controller WHICH WORKS with a normal button GraphView *aSelectionScreenViewController = [[GraphView alloc] initWithNibName:@"GraphView" bundle:nil]; [self presentModalViewController:aSelectionScreenViewController animated: YES]; [aSelectionScreenViewController release]; I searched around and found that I need to set a delegate for the table in the UITableView class itself on the viewload tableview.delegate = self; or self.tableview.delegate = self; But it was not working. the controller was still not being pushed, and yes i have checked the controller is not nil as i tried it with a simple button. So i was thinking whether i should set the delegate of the UITableView at the UIViewController instead, so i tried this code selectionTable.delegate = selectionTable.self; but obviously it did not work =\, it messed up the whole UITableView and caused all the cells to be its predefined settings. So does anybody have any idea on how i can get it to work.

    - by user198880
    I want to add a row whenever the user click on the new button.I want to clone the row "tRow0" and add it to the last row of the table "tblEquipment tbody".I wrote a JavaScript function for adding the row(AddEquipment).The problem is that the row is not getting added in the last row. clone row : tRow0 last row : tRow1 Actually the new row must added after the "tRow1" row.But the new row get added below "trActivity1_2" row.Please provide me the solution. my javascript function: function AddEquipment() { var row = jQuery('#tRow0').clone(true).show().insertAfter('#tblEquipment tbody>tr:last'); var index = document.getElementById("hdnMaxEqpId").value; jQuery("#tblEquipment tbody>tr:last").attr("id", "tRow" + index) jQuery("td:eq(0) input", row).attr("id", "chkEqp" + index); jQuery("td:eq(1) div:eq(0)", row).attr("id", "divEqpName" + index); jQuery("td:eq(1) input:eq(0)", row).attr("id", "hdnWODefEqpId" + index).attr("name", "hdnWODefEqpId" + index); jQuery("td:eq(1) input:eq(1)", row).attr("id", "hdnEquipmentId" + index).attr("name", "hdnEquipmentId" + index).attr("onpropertychange",""); jQuery("td:eq(1) input:eq(2)", row).attr("id", "txtEquipment" + index).attr("name", "txtEquipment" + index); jQuery("td:eq(1) img", row).attr("id", "imgshowEquipmentTree" + index).attr("onclick", ""); jQuery("td:eq(1) div:eq(1)", row).attr("id", "divEqpImage" + index); jQuery("td:eq(2) div", row).attr("id", "divEqpHierarchy" + index); jQuery("td:eq(3) textarea", row).attr("id", "txtEqRemarks" + index); jQuery("td:eq(4) img", row).attr("id", "imgEqAttachment" + index); } my aspx page: <table id="tblEquipment"> <thead> <tr> <th> </th> <th> Equipment</th> <th> Hierarchy</th> <th> Remarks</th> <th> Attachment</th> <th> Total Cost</th> </tr> </thead> <tbody id="tbEquipment"> <tr id="tRow0" class="trChildItem"> <td> <input id="chkEqp0" name="chkEqp0" type="checkbox" /> </td> <td> <div id="divEqpName0"> <input id="hdnWODefEqpId0" name="hdnWODefEqpId0" type="hidden" value="0" /> <input id="hdnEquipmentId0" name="hdnEquipmentId0" onpropertychange="AutoSaveEquipment(0);" type="hidden" value="0" /> <input id="txtEquipment0" class="clsSpText" name="txtEquipment0" readonly /> </div> <div id="divEqpImage0"> </div> </td> <td> <div id="divEqpHierarchy0"> &nbsp;</div> </td> <td> <textarea id="txtEqRemarks0" class="clsSpTextArea" cols="20" name="txtEqRemarks0" rows="1"></textarea> </td> <td> </td> </tr> <tr id="tActMaster0" class="trInnerChildItem"> <td> </td> <td colspan="5"> <div id="divActivitiesdetails0"> </div> </td> </tr> <tr id="tRow1" class="trChildItem"> <td> <input id="chkEqp1" runat="server" type="checkbox" /> <div id="divEqpEdit1"> </div> </td> <td> <div id="divEqpName1"> <input id="hdnWODefEqpId1" runat="server" type="hidden" value="7" /> <input id="hdnEquipmentId1" runat="server" type="hidden" value="4" /> <div id="divEqp1"> e2</div> <div id="divEqpImage1"> <a id="activiy1" onclick="HideActivities(1)"> </div> </td> <td> <div id="divEqpHierarchy1"> Equipment--&gt;e2</div> </td> <td> <div id="divEqpRemarks1"> Remarks</div> </td> <td> <div> </div> </td> <td> <div> $0.00</div> </td> </tr> <tr id="tActMaster1" class="trInnerChildItem" jquery1275984958765="3"> <td> </td> <td colspan="5"> <div id="divActivitiesdetails1"> <div id="divActivityMaster"> <table> <thead> <tr> <th> <a onclick="ActivityPopUp(0,1)"> </a></th> <th> Activity</th> <th> Description</th> <th> Duration</th> </tr> </thead> <tbody id="tbActivity"> <tr id="trActivity1_1" class="trChildItem" ondblclick="ActivityPopUp(3,1)" onmouseleave="HideActEditDiv('1_1')" onmouseover="ShowActEditDiv('1_1',7,1)"> <td> <div id="divActEdit1_1"> </div> </td> <td> <input id="hdnDefActivityId1_1" runat="server" type="hidden" value="33333" /> <div id="divActivityName1_1"> Act1</div> </td> <td> <div id="divActivityDesc1_1"> Ac1</div> </td> <td> <div id="divActivityDuration1_1"> 1&nbsp;Day</div> </td> </tr> <tr id="trActivity1_2" class="trChildItem" ondblclick="ActivityPopUp(3,1)" onmouseleave="HideActEditDiv('1_2')" onmouseover="ShowActEditDiv('1_2',7,1)"> <td> <div id="divActEdit1_2"> </div> </td> <td> <input id="hdnDefActivityId1_2" runat="server" type="hidden" value="4" /> <div id="divActivityName1_2"> Act2</div> </td> <td> <div id="divActivityDesc1_2"> Act2Desc</div> </td> <td> <div id="divActivityDuration1_2"> 1&nbsp;Day</div> </td> </tr> </tbody> </table> </div> </div> </td> </tr> </tbody> </table>

  • form layout in drupal from a module

    - by EricP
    I created my own module called "cssswitch". I'm trying to create my own html layout to display the admin form portion of the module. I understand how to use the hook_form_alter() to modify form elements, but I need to create the entire form layout to make some fields appear next to each other. It seems I need something like the way I have the frontend view of the node displayed with theme_cssswitch_display(), but for the admin part of the node. function cssswitch_form_alter(&$form, $form_state, $form_id) { switch($form_id) { case 'cssswitch_node_form': $form['hour_start']['#prefix'] = '<div class="start-box">'; $form['ampm_start']['#suffix'] = '</div>'; $form['ampm_start']['#attributes'] = array("style" => "border-width:2px;"); break; } } function cssswitch_theme() { return array( 'cssswitch_display' => array( 'arguments' => array('node'), ), ); } // to display the view of the node function theme_cssswitch_display($node) { $output = '<div class="cssswitch-cssfilename">Filename: '. check_plain($node->cssfilename). '</div>'; $output .= '<div class="cssswitch-time_start">Start: '. check_plain($node->hour_start). ':'.check_plain($node->minute_start).' '.check_plain($node->ampm_start).'</div>'; $output .= '<div class="cssswitch-time_end">End: '. check_plain($node->hour_end). ':'.check_plain($node->minute_end).' '.check_plain($node->ampm_end).'</div>'; return $output; } thanks for any help

  • Using Sub-Types And Return Types in Scala to Process a Generic Object Into a Specific One

    - by pr1001
    I think this is about covariance but I'm weak on the topic... I have a generic Event class used for things like database persistance, let's say like this: class Event( subject: Long, verb: String, directobject: Option[Long], indirectobject: Option[Long], timestamp: Long) { def getSubject = subject def getVerb = verb def getDirectObject = directobject def getIndirectObject = indirectobject def getTimestamp = timestamp } However, I have lots of different event verbs and I want to use pattern matching and such with these different event types, so I will create some corresponding case classes: trait EventCC case class Login(user: Long, timestamp: Long) extends EventCC case class Follow( follower: Long, followee: Long, timestamp: Long ) extends EventCC Now, the question is, how can I easily convert generic Events to the specific case classes. This is my first stab at it: def event2CC[T <: EventCC](event: Event): T = event.getVerb match { case "login" => Login(event.getSubject, event.getTimestamp) case "follow" => Follow( event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp ) // ... } Unfortunately, this is wrong. <console>:11: error: type mismatch; found : Login required: T case "login" => Login(event.getSubject, event.getTimestamp) ^ <console>:12: error: type mismatch; found : Follow required: T case "follow" => Follow(event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp) Could someone with greater type-fu than me explain if, 1) if what I want to do is possible (or reasonable, for that matter), and 2) if so, how to fix event2CC. Thanks!
