• NHibernate bag is always null

  - by Neville Chinan

  I have set up my mapping file and classes as suggested by many articles class A { ... IList BBag {get;set;} ... } class B { ... A aObject {get;set;} ... } <class name="A">...<bag name="BBag" table="B" inverse="true" lazy="false"><key column="A_ID" /><one-to-many class="B" /></bag>... <class name="B">...<many-to-one name="aObject" class="A" column="A_ID" />... I added a set of A's to the A table and a set of B's to the B table, all the data is stored as expected. However if I try and access aInstance.BBag.Count I get a null reference exception. I think I missing some key knowledge on how an bag gets instantiated. Thanks

• Ruby on Rails: Unit Testing non activerecord models and still load fixtures

  - by Vaibhav Gumashta

  I may be missing something but I am stuck in this scenario: I have a non activerecord model, which I want to test. I have derived its test case class from: Test::Unit::TestCase. However, the test case class for the model, uses within itself, other activerecord model classes and I want to load fixtures for them. My problem is that the fixtures class method is available only when I subclass the test case class from ActiveSupport::TestCase (it is defined within ActiveRecord::TestFixtures which gets included in ActiveSupport::TestCase). Any help, coz running the tests gives me the error: undefined method "fixtures" (which is understandable) and in case I derive my test case class from ActiveSupport::TestCase it complains that there is no corresponding DB table. Also, I don't want to create a dummy table for backing my model class. Thanks a ton!

• Many-To-Many Query with Linq-To-NHibernate

  - by rjygraham

  Ok guys (and gals), this one has been driving me nuts all night and I'm turning to your collective wisdom for help. I'm using Fluent Nhibernate and Linq-To-NHibernate as my data access story and I have the following simplified DB structure: CREATE TABLE [dbo].[Classes]( [Id] [bigint] IDENTITY(1,1) NOT NULL, [Name] [nvarchar](100) NOT NULL, [StartDate] [datetime2](7) NOT NULL, [EndDate] [datetime2](7) NOT NULL, CONSTRAINT [PK_Classes] PRIMARY KEY CLUSTERED ( [Id] ASC ) CREATE TABLE [dbo].[Sections]( [Id] [bigint] IDENTITY(1,1) NOT NULL, [ClassId] [bigint] NOT NULL, [InternalCode] [varchar](10) NOT NULL, CONSTRAINT [PK_Sections] PRIMARY KEY CLUSTERED ( [Id] ASC ) CREATE TABLE [dbo].[SectionStudents]( [SectionId] [bigint] NOT NULL, [UserId] [uniqueidentifier] NOT NULL, CONSTRAINT [PK_SectionStudents] PRIMARY KEY CLUSTERED ( [SectionId] ASC, [UserId] ASC ) CREATE TABLE [dbo].[aspnet_Users]( [ApplicationId] [uniqueidentifier] NOT NULL, [UserId] [uniqueidentifier] NOT NULL, [UserName] [nvarchar](256) NOT NULL, [LoweredUserName] [nvarchar](256) NOT NULL, [MobileAlias] [nvarchar](16) NULL, [IsAnonymous] [bit] NOT NULL, [LastActivityDate] [datetime] NOT NULL, PRIMARY KEY NONCLUSTERED ( [UserId] ASC ) I omitted the foreign keys for brevity, but essentially this boils down to: A Class can have many Sections. A Section can belong to only 1 Class but can have many Students. A Student (aspnet_Users) can belong to many Sections. I've setup the corresponding Model classes and Fluent NHibernate Mapping classes, all that is working fine. Here's where I'm getting stuck. I need to write a query which will return the sections a student is enrolled in based on the student's UserId and the dates of the class. Here's what I've tried so far: 1. var sections = (from s in this.Session.Linq<Sections>() where s.Class.StartDate <= DateTime.UtcNow && s.Class.EndDate > DateTime.UtcNow && s.Students.First(f => f.UserId == userId) != null select s); 2. var sections = (from s in this.Session.Linq<Sections>() where s.Class.StartDate <= DateTime.UtcNow && s.Class.EndDate > DateTime.UtcNow && s.Students.Where(w => w.UserId == userId).FirstOrDefault().Id == userId select s); Obviously, 2 above will fail miserably if there are no students matching userId for classes the current date between it's start and end dates...but I just wanted to try. The filters for the Class StartDate and EndDate work fine, but the many-to-many relation with Students is proving to be difficult. Everytime I try running the query I get an ArgumentNullException with the message: Value cannot be null. Parameter name: session I've considered going down the path of making the SectionStudents relation a Model class with a reference to Section and a reference to Student instead of a many-to-many. I'd like to avoid that if I can, and I'm not even sure it would work that way. Thanks in advance to anyone who can help. Ryan

• Intermittent NoClassDefFoundError error running Selenium JUnit tests

  - by Matt Sheppard

  For some time, I've been running a substantial set of JUnit / Selenium tests against a number of platforms on a nightly basis. Intermittently (about once in every 40 runs), all the tests for a given platform fail with a NoClassDefFoundError on the common superclass of all my tests as follows. java.lang.NoClassDefFoundError: [common super class of all my selenium tests] at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) at java.lang.Class.getConstructors(Class.java:1459) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) Re-invoking the tests will generally get the tests running normally, so it's clearly something dependent on some condition I am not considering. What might be causing this error to occur seemingly randomly?

• jQuery sortable drop within itself.

  - by Janis Peisenieks

  So my question here is: Can I place a sortable element within another sortable element of the same level. Example: <ul class="sortable"> <li class="subsortable">Some text</li> <li class="subsortable">Some text</li> </ul> into: <ul class="sortable"> <li class="subsortable">Some text<li class="subsortable">Some text</li></li> </ul> I've been trying to do this for a day now, and I can't seem to find a way to do this.

• JPA entity design / cannot delete entity

  - by timaschew

  I though its simple what I want, but I cannot find any solution for my problem. I'm using playframework 1.2.3 and it's using Hibernate as JPA. So I think playframework has nothing to do with the problem. I have some classes (I omit the nonrelevant fields) public class User { ... } public class Task { public DataContainer dataContainer; } public class DataContainer { public Session session; public User user; } public class Session { ... } So I have association from Task to DataContainer and from DataContainer to Sesssion and the DataContainer belongs to a User. The DataContainers can have always the same User, but the Session have to be different for each instance. And the DataContainer of a Task have also to be different in each instance. A DataContainer can have a Sesesion or not (it's optinal). I use only unidirectional assoc. It should be sufficient. In other words: Every Task must has one DataContainer. Every DataContainer must has one/the same User and can have one Session. To create a DB schema I use JPA annotations: @Entity public class User extends Model { ... } @Entity public class Task extends Model { @OneToOne(optional = false, cascade = CascadeType.ALL) public DataContainer dataContainer; } @Entity public class DataContainer extends Model { @OneToOne(optional = true, cascade = CascadeType.ALL) public Session session; @ManyToOne(optional = false, cascade = CascadeType.ALL) public User user; } @Entity public class Session extends Model { ... } BTW: Model is a play class and provides the primary id as long type. When I create some for each entity a object and 'connect them', I mean the associations, it works fine. But when I try to delete a Session, I get a constraint violation exception, because a DataContainer still refers to the Session I want to delete. I want that the Session (field) of the DataContainer will be set to null respectively the foreign key (session_id) should be unset in the database. This will be okay, because its optional. I don't know, I think I have multiple problems. Am I using the right annotation @OneToOne ? I found on the internet some additional annotation and attributes: @JoinColumn and a mappedBy attribute for the inverse relationship. But I don't have it, because its not bidirectional. Or is a bidirectional assoc. essentially? Another try was to use @OnDelete(action = OnDeleteAction.CASCADE) the the contraint changed from NO ACTIONs when update or delete to: ADD CONSTRAINT fk4745c17e6a46a56 FOREIGN KEY (session_id) REFERENCES annotation_session (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE; But in this case, when I delete a session, the DataContainer and User is deleted. That's wrong for me. EDIT: I'm using postgresql 9, the jdbc stuff is included in play, my only db config is db=postgres://app:app@localhost:5432/app

• The "correct" way to define an exception in Python without PyLint complaining

  - by Evgeny

  I'm trying to define my own (very simple) exception class in Python 2.6, but no matter how I do it I get some warning. First, the simplest way: class MyException(Exception): pass This works, but prints out a warning at runtime: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6 OK, so that's not the way. I then tried: class MyException(Exception): def __init__(self, message): self.message = message This also works, but PyLint reports a warning: W0231: MyException.__init__: __init__ method from base class 'Exception' is not called. So I tried calling it: class MyException(Exception): def __init__(self, message): super(Exception, self).__init__(message) self.message = message This works, too! But now PyLint reports an error: E1003: MyException.__init__: Bad first argument 'Exception' given to super class How the hell do I do such a simple thing without any warnings?

• My form submit button is not showing correctly

  - by JackR

  I have created an form that submits the contents to email. I have used the exact same coding in many other websites, but for my new website http://www.peterevansfuneraldirectors.co.uk/contact-us.html the submit button is just a grey square with text, rather than the usual button. Also the hand doesn't come up on hover. My form code is... <form action="php/FormToEmail.php" method="post" name="ContactForm" id="ContactForm" onsubmit="MM_validateForm('name','','R','email','','RisEmail','message subject','','R','message','','R');return document.MM_returnValue" > <div class="form-text"> <b>Name<span class="purple">*</span></b><br /> <input name="name" type="text" id="name" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Email<span class="purple">*</span></b><br /> <input name="email" type="text" id="email" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Message Subject<span class="purple">*</span></b><br /> <input name="message subject" type="text" id="message subject" size="35" style="height:23px; background-color:#FFF; color:#000; border: 1px solid #CCC;" /> </div><br /> <div class="form-text"> <b>Message<span class="purple">*</span></b><br /> <textarea name="message" type="text" id="message" rows="8" cols="55" style="background-color:#FFF; color:#000; border: 1px solid #CCC;" ></textarea> </div><br /> <div class="submit-button"> <input type="submit" name="submit" value="Submit" /> </div> </form> Thanks in advance!

• ASP.NET Application Level vs. Session Level and Global.asax...confused

  - by contactmatt

  The following text is from the book I'm reading, 'MCTS Self-Paced Training Kit (Exam 70-515) Web Applications Development with ASP.NET 4". It gives the rundown of the Application Life Cycle. A user first makes a request for a page in your site. The request is routed to the processing pipeline, which forwards it to the ASP.NET runtime. The ASP.NET runtime creates an instance of the ApplicationManager class; this class instance represents the .NET framework domain that will be used to execute requests for your application. An application domain isolates global variables from other applications and allows each application to load and unload separately, as required. After the application domain has been created, an instance of the HostingEnvironment class is created. This class provides access to items inside the hosting environment, such as directory folders. ASP.NET creates instances of the core objects that will be used to process the request. This includes HttpContext, HttpRequest, and HttpResponse objects. ASP.NET creates an instance of the HttpApplication class (or an instance is reused). This class is also the base class for a site’s Global.asax file. You can use this class to trap events that happen when your application starts or stops. When ASP.NET creates an instance of HttpApplication, it also creates the modules configured for the application, such as the SessionStateModule. Finally, ASP.NET processes request through the HttpApplication pipleline. This pipeline also includes a set of events for validating requests, mapping URLs, accessing the cache, and more. The book then demonstrated an example of using the Global.asax file: <script runat="server"> void Application_Start(object sender, EventArgs e) { Application["UsersOnline"] = 0; } void Session_Start(object sender, EventArgs e) { Application.Lock(); Application["UsersOnline"] = (int)Application["UsersOnline"] + 1; Application.UnLock(); } void Session_End(object sender, EventArgs e) { Application.Lock(); Application["UsersOnline"] = (int)Application["UsersOnline"] - 1; Application.UnLock(); } </script> When does an application start? Whats the difference between session and application level? I'm rather confused on how this is managed. I thought that Application level classes "sat on top of" an AppDomain object, and the AppDomain contained information specific to that Session for that user. Could someone please explain how IIS manages Applicaiton level classes, and how an HttpApplication class sits under an AppDomain? Anything is appreciated.

• Can not access response.body inside after filter block in Sinatra 1.0

  - by Petr Vostrel

  I'm struggling with a strange issue. According to http://github.com/sinatra/sinatra (secion Filters) a response object is available in after filter blocks in Sinatra 1.0. However the response.status is correctly accessible, I can not see non-empty response.body from my routes inside after filter. I have this rackup file: config.ru require 'app' run TestApp Then Sinatra 1.0.b gem installed using: gem install --pre sinatra And this is my tiny app with a single route: app.rb require 'rubygems' require 'sinatra/base' class TestApp < Sinatra::Base set :root, File.dirname(__FILE__) get '/test' do 'Some response' end after do halt 500 if response.empty? # used 500 just for illustation end end And now, I would like to access the response inside the after filter. When I run this app and access /test URL, I got a 500 response as if the response is empty, but the response clearly is 'Some response'. Along with my request to /test, a separate request to /favicon.ico is issued by the browser and that returns 404 as there is no route nor a static file. But I would expect the 500 status to be returned as the response should be empty. In console, I can see that within the after filter, the response to /favicon.ico is something like 'Not found' and response to /test really is empty even though there is response returned by the route. What do I miss?

• Floated DIVs not flowing properly

  - by NightMICU

  Hi everyone, I am working on a photo gallery, each thumbnail is in its own DIV and floated to the left in a containing DIV. It has been displaying properly up until vertical thumbnails entered the equation. Now, when the next row should start, the first item of the following row is to the left of the last vertical DIV (thumbnail), rather than flush to the left of the containing DIV. Here is the CSS: #galleryBox { width: 650px; background: #fff; margin: auto; padding: 10px; text-align: center; overflow: auto; } .item { display: block; margin: 10px; padding: 20px 5px 5px 5px; float: left; background: url('/images/content_bottom.png') repeat-x scroll bottom #828282; } and the HTML: <div id="galleryBox" class="ui-corner-all"> <div id="file" class="ui-corner-all"> <form name="uploadPhoto" id="uploadPhoto" method="post" action="" enctype="multipart/form-data"> <p><label for="photo">Photo:</label><input type="file" name="photo" id="photo"/></p> <p><label for="caption">Caption: <small>Optional</small></label><input type="text" id="caption" name="caption"/></p> <p align="center"><input type="submit" value="Upload" name="send" id="send" class="addButton ui-state-default ui-corner-all"/></p> </form> <a name="thumbs"></a> </div> <div class="item ui-corner-all"> <a href="http://tapp-essexvfd.org/gallery/photos/201004211802.jpg" class="lightbox" title="test1"> <img src="http://tapp-essexvfd.org/gallery/photos/thumbs/201004211802_thumb.jpg" alt="test1"/></a><br/> <p><span class="label">test1</span></p> </div> <div class="item ui-corner-all"> <a href="http://tapp-essexvfd.org/gallery/photos/201004211803.jpg" class="lightbox" title="test3"> <img src="http://tapp-essexvfd.org/gallery/photos/thumbs/201004211803_thumb.jpg" alt="test3"/></a><br/> <p><span class="label">test3</span></p> </div> </div>

• jQuery: modify href attribute for first level list only

  - by bloggerious

  I'm a noob in jQuery and have stuck at this. I have the following HTML code output from a PHP page: <ul class="cats"> <li><span><a href="cant_post_link_yet1">Lifestyle</a></span></li> <li><span><a href="cant_post_link_yet2">Entertainment</a></span></li> <li class="has_child"> <span><a href="cant_post_link_yet3">Technology</a></span> <ul class="subcats"> <li><span><a href="cant_post_link_yet4">Gadgets</a></span></li> <li><span><a href="cant_post_link_yet5">Hardware</a></span></li> </ul> </li> <li><span><a href="cant_post_link_yetsports">Sports</a></span></li> <li class="has_child"> <span><a href="cant_post_link_yet6">Design</a></span> <ul class="subcats"> <li class="has_child"> <span><a href="cant_post_link_yet7">Web Design</a></span> <ul class="subcat"> <li><span><a href="cant_post_link_yet8">Adobe Photoshop</a></span></li> </ul> </li> <li><span><a href="cant_post_link_yet9">Graphics and Print</a></span></li> </ul> </li> What's the correct jQuery code so that I can modify the href attribute for the first-level list only? Basically, I want to change the href of Technology and Design to be "#" but will not change the href of Web Design which is already on second-level list. More Info: In the code above, if list has subcategories, then it has the class has_child, whether it's on first-level or not. So I want only the first-level list which has class has_child to be modified the href to "#" I can't alter output anymore because it's in the PHP code. Any help is greatly appreciated.

• C# Combobox and TabControl woes

  - by Jake

  enter code hereI have a TabControl on a Form and in the TabPages there are ComboBoxes. When the form OnLoad, I populate the ListItems in the ComboBoxes and the attempt to set default values to string.Empty. However, the ComboBox.SelectedText = string.Empty only works for the first TabPage. The other ComboBoxes ignore the command and take the default value as the first item in the list. Why is this so? How can I overcome it? The ComboBoxes are all set up by this function public static void PrepareComboBox(ComboBox combobox, FieldValueList list) { combobox.DropDownStyle = ComboBoxStyle.DropDown; combobox.AutoCompleteSource = AutoCompleteSource.ListItems; combobox.AutoCompleteMode = AutoCompleteMode.Suggest; combobox.DataSource = list.DataSource; combobox.DisplayMember = list.DisplayMember; combobox.ValueMember = list.ValueMember; combobox.Text = string.Empty; combobox.SelectedText = string.Empty; }

• How to prevent google chrome from caching my inputs, esp hidden ones when user click back?

  - by melaos

  hi there, i have an asp.net mvc app which have quite a few hidden inputs to keep values around and formatting their names so that i can use the Model binding later when i submit the form. i stumble into a weird bug with chrome which i don't have with IE or Firefox when the user submits the form and click on the back button, i find that chrome will keep my hidden input values as well. this whole chunk is generated via javascript hence i believe chrome is caching this. function addProductRow(productId, productName) { if (productName != "") { //use guid to ensure that the row never repeats var guid = $.Guid.New(); var temp = parseFloat($(".tboProductCount").val()); //need the span to workaround for chrome var szHTML = "<tr valign=\"top\" id=\"productRow\"><td class=\"productIdCol\"><input type=\"hidden\" id=productRegsID" + temp + "\" name=\"productRegs[" + temp + "].productId\" value=\"" + productId + "\"/>" + "<span id=\"spanProdID" + temp + "\" name=\"spanProdID" + temp + "\" >" + productId + "</span>" + "</td>" //+ "<td><input type=\"text\" id=\"productRegName\" name=\"productRegs[" + temp + "].productName\" value=\"" + productName + "\" class=\"productRegName\" size=\"50\" readonly=\"readonly\"/></td>" + "<td><span id=\"productRegName\" name=\"productRegs[" + temp + "].productName\" class=\"productRegName\">"+ productName + "<\span></td>" + "<td id=\"" + guid + "\" class=\"productrowguid\" \>" + "<input type=\"text\" size=\"20\" id=\"productSerialNo" + temp + "\" name=\"productRegs[" + temp + "].serialNo\" value=\"" + "\" class=\"productSerialNo\" maxlength=\"18\" />" + "<a class=\"fancybox\" id=\"btnImgSerialNo" + temp + "\" href=\"#divSerialNo" + temp + "\"><img class=\"btnImgSerialNo\" src=\"Images/landing_14.gif\" /></a>" + "<span id=\"snFlag" + temp + "\" class=\"redWarning\"></span></td>" + "<td><input type=\"text\" id=\"productRegDate" + temp + "\" name=\"productRegs[" + temp + "].PurchaseDate\" readonly=\"readonly\" />" + "<span id=\"snRegDate" + temp + "\" class=\"redWarning\"></span></td>" + "<td align=\"center\"><img style=\"cursor:pointer\" id=\"btnImgDelete\" src=\"Images/btn_remove.gif\" onclick=\"javascript:removeProductRow('" + guid + "')\" /><div style=\"display:none;\"><div id=\"divSerialNo" + temp + "\" style=\"font-family:verdana;font-size:11px;width:600px\">" + serialnumbergeneral + "<br /><br />" + getSNImageByCategory(productId) + "</div></div></td>" + "</tr>"; $(".ProductRegistrationTable").append(szHTML); $("a.fancybox").fancybox(); //initialization $("#productRegDate" + temp).datepicker({ minDate: new Date(1996, 1 - 1, 1), maxDate: 0 }); //sanity check //s7test alert('1 '+$("#spanProdID" + temp)); alert('2 '+$("#productRegsID" + temp)); } //end function addNewProductRow i need the id to be refreshed when the user select a new product, but putting another span tag beside it shows that the span will have the new id will the hidden input will still have the previous id. is there an elegant way to workaround this issue? thanks

• Hibernate configuration - session factory scanning?

  - by Marcus

  We have this hibernate.cfg.xml file. Is there a way to tell Hibernate to just scan a directory instead of having to add an entry here for each class? <hibernate-configuration> <session-factory> <mapping class="com.abc.domain.model.A" /> <mapping class="com.abc.domain.model.B" /> <mapping class="com.abc.domain.model.C" /> <mapping class="com.abc.domain.model.D" /> <mapping class="com.abc.domain.model.E" /> </session-factory> </hibernate-configuration>

• Forcing Flex to update the screen?

  - by ABBarton

  This may be a bit of a beginners question, but I can't for the life of me figure it out. I'm using flex to develop a GUI for a large project, specifically a status bar along the bottom. Within my StatusBar class is a ProgressBar, which other classes doing work can tell to update(change bar completion and label) as they progress. The problem I'm encountering is that flex won't update whats shown on the screen until it's too late, for example ProgressBar initialized, 0% done some class sets the ProgressBar to be 12% done some class does some work some class sets the ProgressBar to be 56% done Whats happening is the 12% done is never displaying, it just hangs at 0% during the work, then skips right to 56% done. I've tried to understand the lifecycle of a flex component (invalidation and validation), and I think I understand it and am applying it correctly, but it's not working at all. I need to tell flex to redraw my StatusBar (or at least the ProgressBar within) after some class sets it to be 12% done, but before some class starts doing its work. How do I do this?

• Jquery mobile page structure

  - by Die 20

  I built a jquery mobile site a while back and I have recently been expanding on it and noticing performance issues. I believe it is because I constructed the site using a multi-page set up where a single php file houses the following pages: **ALL_PAGES.PHP** <html> <head> /* external css and js files */ </head> <body> <div date-role="page" id="main"> <div class="page_link"> page 1 </div> <div class="page_link"> page 2 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 1"> <div class="page_link"> main </div> <div class="page_link"> page 2 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 2"> <div class="page_link"> main </div> <div class="page_link"> page 1 </div> <div class="page_link"> page 3 </div> </div> <div date-role="page" id="page 3"> <div class="page_link"> main </div> <div class="page_link"> page 1 </div> <div class="page_link"> page 2 </div> </div> </body> </html> **end ALL_PAGES.PHP ** I want to break away from this multi-page setup on one php file, and move to a setup where each page is a separate php file. To accomplish this I took the html from each page and moved it to its own php page. Then I added href links in replace of the mobile.change() functions I used for the "page_link" classes. **MAIN.PHP** <html> <head> external css and js files </head> <body> <div date-role="page" id="page 1"> <a href="/main.php"> main </a> <a href="/page_2.php"> page 2 </a> <a href="/page_3.php"> page 3 </a> </div> </body> </html> **end MAIN.PHP** **PAGE_1.PHP** <div date-role="page" id="page 1"> <a href="/main.php"> main </a> <a href="/page_2.php"> page 2 </a> <a href="/page_3.php"> page 3 </a> </div> **end PAGE_1.PHP** **PAGE_2.PHP** <div date-role="page" id="page 2"> <a href="/main.php"> main </a> <a href="/page_1.php"> page 1 </a> <a href="/page_3.php"> page 3 </a> </div> **end PAGE_2.PHP** **PAGE_3.PHP** <div date-role="page" id="page 3"> <a href="/main.php"> main </a> <a href="/page_1.php"> page 1 </a> <a href="/page_2.php"> page 2 </a> </div> **end PAGE_3.PHP** The site works fine except when the user hits the refresh button in the browser. When that happens each page loses access to any external css and js files located on the main page. I am fairly new to JQM so any advice would be helpful.

• Python: User-Defined Exception That Proves The Rule

  - by bandana

  Python documentations states: Exceptions should typically be derived from the Exception class, either directly or indirectly. the word 'typically' leaves me in an ambiguous state. consider the code: class good(Exception): pass class bad(object): pass Heaven = good() Hell = bad() >>> raise Heaven Traceback (most recent call last): File "<pyshell#163>", line 1, in <module> raise Heaven good >>> raise Hell Traceback (most recent call last): File "<pyshell#171>", line 1, in <module> raise Hell TypeError: exceptions must be classes or instances, not bad so when reading the python docs, should i change 'typically' with ''? what if i have a class hierarchy that has nothing to do with the Exception class, and i want to 'raise' objects belonging to the hierarchy? i can always raise an exception with an argument: raise Exception, Hell This seems slightly awkward to me What's so special about the Exception class, that only its family members can be raised?

• How can I Query only __key__ on a Google Appengine PolyModel child?

  - by Gabriel

  So the situation is: I want to optimize my code some for doing counting of records. So I have a parent Model class Base, a PolyModel class Entry, and a child class of Entry Article: How would I query Article.key so I can reduce the query load but only get the Article count. My first thought was to use: q = db.GqlQuery("SELECT __key__ from Article where base = :1", i_base) but it turns out GqlQuery doesn't like that because articles are actually stored in a table called Entry. Would it be possible to Query the class attribute? something like: q = db.GqlQuery("select __key__ from Entry where base = :1 and :2 in class", i_base, 'Article') neither of which work. Turns out the answer is even easier. But I am going to finish this question because I looked everywhere for this. q = db.GqlQuery("select __key__ from Entry where base = :1 and class = :2", i_base, 'Article')
