  • jcarousel, I need :active state on external controls

    - by TJ Sherrill
    I am running a Jcarousel and I want to add a.active to the current pagination option. I have seen other posts around about this same thing. /** * We use the initCallback callback * to assign functionality to the controls */ function mycarousel_initCallback(carousel) { jQuery('.jcarousel-control a').bind('click', function() { carousel.scroll(jQuery.jcarousel.intval(jQuery(this).text())); return false; }); jQuery('#mycarousel-next').bind('click', function() { carousel.next(); return false; }); jQuery('#mycarousel-prev').bind('click', function() { carousel.prev(); return false; }); }; // Ride the carousel... jQuery(document).ready(function() { jQuery("#mycarousel").jcarousel({ scroll: 1, initCallback: mycarousel_initCallback, // This tells jCarousel NOT to autobuild prev/next buttons buttonNextHTML: null, buttonPrevHTML: null }); }); </script> Thats the initialize code and the pagination lives inside: <ul class="jcarousel-control"> <% ([email protected]).each do |n| %> <li><a href="#"> <%= n %></a></li> <% end %> </ul> Its a rails app, so rails is creating the list based on the number of projects in the group. Any ideas? Seems like it should be pretty simple.. But I don't know js at all.

  • javax.naming.NameAlreadyBoundException: in glassfish server v2

    Hi! I'm implementing stateless session bean ejb3 in glassfish server using netbeans. First time, it is working properly.

  • Help with MySQL query - Product orders report without duplicate shipping charges

    - by Paul
    Hello, I have an issue creating a custom report for an e-commerce store running on osCommerce. The client wants the report to have the following columns: Date, Order ID, Product Class, Product Price, Product Tax, Shipping, Order Total The criteria for generating the report are Date Range and Product Class (Textbooks for example) The client wants the report to list each Textbook purchased on its own line. Orders with multiple textbooks would display a separate line for each Textbook in the order. I have it all working except for one part: the shipping amount is order-specific (based on the order total), not product-specific, and is displaying for each product. I need it to display only for the first product of each order, so it is not counted more than once. My current query is: SELECT op.date_funds_captured as 'Date', op.orders_id as 'Order ID', pc.class as 'Product Class', round(op.products_price,2) as 'Product Price', round(op.products_tax*op.products_price/100,2) as 'Product Tax', round(otship.value,2) as 'Shipping', round(ot.value,2) as 'Order Total' from orders_products op, orders_total ot, orders_total otship, productclasses pc, products p where ot.orders_id = op.orders_id and ot.class='ot_total' and op.orders_id = otship.orders_id and otship.class = 'ot_shipping' and p.products_class_id = pc.id and op.products_id = p.products_id and pc.id = 1 pc.id = 1 -- Product class = Textbook Here is an example of the current report output. You can see the problem with order 2256 showing the shipping value three times instead of once: Date Order Product Class Price Tax Shipping Total 2010-01-04 2253 Textbook 24.95 2.43 10.03 37.41 2010-01-04 2256 Textbook 34.95 0.00 18.09 240.37 2010-01-04 2256 Textbook 55.50 0.00 18.09 240.37 2010-01-04 2256 Textbook 36.95 0.00 18.09 240.37 2010-01-04 2258 Textbook 55.50 5.41 12.17 124.24 Please help!!!

  • Flexible Decorator Pattern?

    - by Omar Kooheji
    I was looking for a pattern to model something I'm thinking of doing in a personal project and I was wondering if a modified version of the decorator patter would work. Basicly I'm thinking of creating a game where the characters attributes are modified by what items they have equiped. The way that the decorator stacks it's modifications is perfect for this, however I've never seen a decorator that allows you to drop intermediate decorators, which is what would happen when items are unequiped. Does anyone have experience using the decorator pattern in this way? Or am I barking up the wrong tree? Clarification To explain "Intermediate decorators" if for example my base class is coffe which is decorated with milk which is decorated with sugar (using the example in Head first design patterns) milk would be an intermediate decorator as it decorates the base coffee, and is decorated by the sugar. Yet More Clarification :) The idea is that items change stats, I'd agree that I am shoehorning the decorator into this. I'll look into the state bag. essentially I want a single point of call for the statistics and for them to go up/down when items are equiped/unequiped. I could just apply the modifiers to the characters stats on equiping and roll them back when unequiping. Or whenever a stat is asked for iterate through all the items and calculate the stat. I'm just looking for feedback here, I'm aware that I might be using a chainsaw where scissors would be more appropriate...

  • Export SWC from Flash and Access Child from Flex

    - by php html
    I'm creating an actionscript project in Flex Builder. I succeed to export from Flash a SWC file, and to use it succesfully in Flex. I have a good programming background and Flex looks very simple for me, but I have difficult times in flash. I'm trying to achieve something that might be very simple(not for me of course): I create a simple shape in Flash, convert it to symbol. Then I create a TextField. The I select both the elements and convert them to another symbol, and Export it as a movieclip in swc. In flex I want to change the value from the textfield. How should I do? I'm trying to do: var t:ExportedMC = new ExportedMC(); t....(what should I write here) As I mentioned when I open flash I feel like an elephant in a porcelain store. I have 2 questions here: - how to assign a name to the textfield in flash? I'm using CS4. - how to access it as a child in flex?

  • Connect two client sockets

    - by Hernán Eche
    Good morning, let's say Java has two kind of sockets... server sockets "ServerSocket" client sockets or just "Socket" ////so Simple ! Imagine the situation of two processes: X Client <-- Y Server The server process Y : has a "ServerSocket", that is listening to a TCP port The client process X : send a connection request through a -client type- "Socket" X ////so Simple ! then the accept() method (in server Y) returns a new client type "Socket", when it occurs, great the two Sockets get "interconected", so the -client socket- in client process, is connected with the -client socket- in the server process then (reading/writing in socket X is like reading/writing in socket Y, and viceversa. ) TWO CLIENT SOCKETS GET INTERCONECTED!! ////so Simple ! BUT... (there is always a But..) What if I create the two CLIENT sockets in same process, and I want to get them "interconected" ? ////mmm Complex =(... even posible? Let's say how to have TWO CLIENT SOCKETS GET INTERCONECTED WITHOUT using an intermediate ServerSocket ? I 've solved it.. by creating two threads for continuously reading A and writing B, and other for reading B and writng A... but I think could be a better way..(or should!) (Those world-energy-consuming threads are not necessary with the client-server aproach) Any help or advice would be appreciated!! Thanks

  • How to access a method on a generic datacontext which is only created at runtime

    - by Jeremy Holt
    I'm creating my generic DataContext using only the connectionString in the ctor. I have no issues in retrieving the table using DataContext.GetTable(). However, I need to also be able to retrieve entities of inline table functions. The dbml designer generates public IQueryable<testFunctionResult> testFunction() { return this.CreateMethodCallQuery<testFunctionResult>(this, ((MethodInfo)(MethodInfo.GetCurrentMethod()))); } The question is how do I get the MethodInfo.GetCurrentMethod() when the DataContext has no method called "testFunction", i.e.typeof(DataContext).GetMethod("testFunction") returns null? What I'm trying to achieve is something like: public class UnitofWork<T> { public UnitofWork(string connectionString) { this.DataContext = new DataContext(connectionString); } public UnitofWork(IQueryable<T> tableEntity) { _tableEntity = tableEntity; } public IQueryable<T> TableEntity { get { if (DataContext == null) return _tableEntity; var metaType = DataContext.Mapping.GetMetaType(typeof (T)); if (metaType.IsEntity) _tableEntity = DataContext.GetTable<T>(); else { var s = typeof(T).Name; string methodName = s.Substring(0, s.IndexOf("Result")) + "()"; // the designer automatically affixes "Result" to the type name // Make a method from methodName // _tableEntity = DataContext.CreateMethodCallQuery(DataContext, method, new object[]{}); } return _tableEntity; } set { _tableEntity = value; } } ) Thanks in advance for any insight Jeremy

  • JQuery datepicker not working

    - by IniTech
    I'm completely new to JQuery and MVC. I'm working on a pet project that uses both to learn them and I've hit my first snag. I have a date field and I want to add the JQuery datepicker to the UI. Here is what I have done: Added <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> to the site.master Inside my Create.aspx (View), I have <asp:Content ID="Create" ContentPlaceHolderID="MainContent" runat="server"> <h2> Create a Task</h2> <% Html.RenderPartial("TaskForm"); %> </asp:Content> and inside "TaskForm" (a user control) I have: <label for="dDueDate"> Due Date</label> <%= Html.TextBox("dDueDate",(Model.Task.TaskID > 0 ? string.Format("{0:g}",Model.Task.DueDate) : DateTime.Today.ToString("MM/dd/yyyy"))) %> <script type="text/javascript"> $(document).ready(function() { $("#dDueDate").datepicker(); }); </script> As you can see, the above checks to see if a task has an id 0 (we're not creating a new one) if it does, it uses the date on the task, if not it defaults to today. I would expect the datepicker UI element to show up, but instead I get: "Microsoft JScript runtime error: Object doesn't support this property or method" on the $("#dDueDate").datepicker(); Ideas? It is probably a very simple mistake, so don't over-analyze. As I said, this is the first time I've dealt with MVC or JQuery so I'm lost as to where to start.

  • How can I serialize and communicate ActiveRecord instances across identical Rails apps?

    - by Blaine LaFreniere
    The main idea is that I have several worker instances of a Rails app, and then a main aggregate I want to do something like this with the following pseudo pseudo-code posts = Post.all.to_json( :include => { :comments => { :include => :blah } }) # send data to another, identical, exactly the same Rails app # ... # Fast forward to the separate but identical Rails app: # ... # remote_posts is the posts results from the first Rails app posts = JSON.parse(remote_posts) posts.each do |post| p = Post.new p = post p.save end I'm shying away from Active Resource because I have thousands of records to create, which would mean thousands of requests for each record. Unless there is a way to do it all in one request with Active Resource that is simple, I'd like to avoid it. Format doesn't matter. Whatever makes it convenient. The IDs don't need to be sent, because the other app will just be creating records and assigning new IDs in the "aggregate" system. The hierarchy would need to be preserved (E.g. "Hey other Rails app, I have genres, and each genre has an artist, and each artist has an album, and each album has songs" etc.)

  • Adobe AIR non-Administrator application installation/upgrade on Windows

    - by bzlm
    Is there any way to allow non-Administrator users to install, upgrade or uninstall an Adobe AIR application on Windows? I've made an Adobe AIR application and packaged it as a .air package using the standard AIR mechanism for creating deployment packages. If a normal or Power user tries to install this AIR application, the Application Event Log shows an error saying administrative rights are required. And even if the user elevates during installation, administrative rights are still required for an upgrade using the automated AIR upgrade system (since an upgrade is essentially, behind the scenes, an uninstallation of a .msi package followed by an installation of another .msi package). Is there any way around this? What I've tried so far is: Using the Group Policy editor, setting Windows Installer to elevate during installations. Doesn't work, since AIR attempts a "for all users" installation. Specifying My Documents as the installation directory. Doesn't work, since AIR attempts a "for all users" installation. Giving the user Modify access to the Program Files folder where the application would usually reside. Doesn't work, since this isn't a file permissions issue. Making the user a Power User. Doesn't work, since AIR attempts a "for all users" installation. I'm guessing that both installing and upgrading would work fine for a user if the AIR installer would attempt to make an "only for me" application installation instead of a "for all users" installation, and the user was a Power User, and possibly the application was installed to My Documents I'm also guessing that this problem doesn't exist on OSX and Linux, since they have more intuitive concepts for per-user application installations.

  • How to access empty ASP.NET ListView.ListViewItem to apply a style after all databinding is done?

    - by Caroline S.
    We're using a ListView with a GroupTemplate to create a three-column navigation menu with six items in each column, filling in two non-data-bound rows in the last column with an EmptyItemTemplate that contains an empty HTML list item. That part works fine, but I also need to programmatically add a CSS class to the sixth (last) item in each column. That part is also working fine for the first two columns because I'm assigning the CSS class in the DataBound event, where I can iterate through the ListView.Items collection and access the sixth item in the first two columns by using a modulus operator and counter. The problem comes in the last column, where the EmptyItemTemplate has correctly filled in two empty list items, to the last of which I also need to add this CSS class. The empty items are not included in the ListView.Items collection (that's just ListViewDataItems, and the empty items are ListViewItems). I cannot find a way to access the entire collection of ListViewItems after binding. Am I missing something? I know I can access the empty items during ItemCreated, but I can't figure out how to determine where the item I'm creating falls in the flow, and whether it's the last one. Any help would be appreciated, if this can even be done -- I'm a bit stuck.

  • OpenGL/Carbon/Cocoa Memory Management Autorelease issue

    - by Stephen Furlani
    Hoooboy, I've got another doozy of a memory problem. I'm creating a Carbon (AGL) Window, in C++ and it's telling me that I'm autorelease-ing it without a pool in place. uh... what? I thought Carbon existed outside of the NSAutoreleasePool... When I call glEnable(GL_TEXTURE_2D) to do some stuff, it gives me a EXC_BAD_ACCESS warning - but if the AGL Window is never getting release'd, then shouldn't it exist? Setting set objc-non-blocking-mode at (gdb) doesn't make the problem go away. So I guess my question is WHAT IS UP WITH CARBON/COCOA/NSAutoreleasePool? And... are there any resources for Objective-C++? Because crap like this keeps happening to me. Thanks, -Stephen --- CODE --- Test Draw Function void Channel::frameDraw( const uint32_t frameID) { eq::Channel::frameDraw( frameID ); getWindow()->makeCurrent(false); glEnable(GL_TEXTURE_2D); // Throws Error Here } Make Current (Equalizer API from Eyescale) void Window::makeCurrent( const bool useCache ) const { if( useCache && getPipe()->isCurrent( this )) return; _osWindow->makeCurrent(); } void AGLWindow::makeCurrent() const { aglSetCurrentContext( _aglContext ); AGLWindowIF::makeCurrent(); if( _aglContext ) { EQ_GL_ERROR( "After aglSetCurrentContext" ); } } _aglContext is a valid memory location (i.e. not NULL) when I step through. -S!

  • Add data to Django form class using modelformset_factory

    - by dean
    I have a problem where I need to display a lot of forms for detail data for a hierarchical data set. I want to display some relational fields as labels for the forms and I'm struggling with a way to do this in a more robust way. Here is the code... class Category(models.Model): name = models.CharField(max_length=160) class Item(models.Model): category = models.ForeignKey('Category') name = models.CharField(max_length=160) weight = models.IntegerField(default=0) class Meta: ordering = ('category','weight','name') class BudgetValue(models.Model): value = models.IntegerField() plan = models.ForeignKey('Plan') item = models.ForeignKey('Item') I use the modelformset_factory to create a formset of budgetvalue forms for a particular plan. What I'd like is item name and category name for each BudgetValue. When I iterate through the forms each one will be labeled properly. class BudgetValueForm(forms.ModelForm): item = forms.ModelChoiceField(queryset=Item.objects.all(),widget=forms.HiddenInput()) plan = forms.ModelChoiceField(queryset=Plan.objects.all(),widget=forms.HiddenInput()) category = "" < assign dynamically on form creation > item = "" < assign dynamically on form creation > class Meta: model = BudgetValue fields = ('item','plan','value') What I started out with is just creating a dictionary of budgetvalue.item.category.name, budgetvalue.item.name, and the form for each budget value. This gets passed to the template and I render it as I intended. I'm assuming that the ordering of the forms in the formset and the querset used to genererate the formset keep the budgetvalues in the same order and the dictionary is created correctly. That is the budgetvalue.item.name is associated with the correct form. This scares me and I'm thinking there has to be a better way. Any help would be greatly appreciated.

  • JAVA vs .NET - Choice for way to go further [closed]

    - by Sarang
    I have my subject .Net acedemically. I also learned core Java and did a project as well. I took training from a Java firm. Now, as a skill I do have knowledge as both language. But, it is creating a large problem to me that, which field I should chhose? Even if having better OOP fundamentals, will it be easier for me to transfer from one to another in the future ? Please suggest me a way. Also, we do have may technologies available at both side, like JSP, JSF, J2ME, Share Point, SilverLight etc. Which is better as per their reliabity point of view? Which are fast growing and useful technologies used mostly in current IT corporate world ? Are they easier to learn at fresher's point of view? Please answer. Perhaps, this answer may help me mostly to create my way to learn them and go further. Every IT developer, please help to find me my way.

  • Set initial view with SkpWriter in Google Sketchup C++ SDK

    - by Peter Olsson
    How do you set the initial view for the model in an SKP file created with the SkpWriter in Google Sketchup C++ SDK? There has been an example in an older version of the SDK. Part of the source is posted here. I'm trying to use: m_pDoc->GetModel()->SetCamera(cameraDefn); The problem is that I'm not able to create a valid atlast::sketchup::CCameraDefinition. Non of the examples in the above post works: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); and: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); In the end I want the initial view to be the view you get from pressing the icon for Zoom extents followed by the Iso icon (the other way around is also ok). Right now I would settle for creating a valid atlast::sketchup::CCameraDefinition. Any better way to achieve this in the SKP-file?

  • Producing CCITT compressed TIFF from CGImage

    - by Brian Postow
    I have a CGImage (core graphics, C/C++). It's grayscale. Well, originally it was B/W, but the CGImage may be RGB. That shouldn't matter. I want to create a CCITT-Group 4 TIFF. I can create an LZW TIFF (grayscale or color) via creating a destination with the correct dictionary and adding the image in. No problem. However, there doesn't seem to be an equivalent kCGImagePropertyTIFFCompression value to represent CCITT-4. It should be 4, but that produces uncompressed. I have a manual CCITT compression routine, so if I can get the binary (1 bit per pixel) data, I'm set. But I can't seem to get 1 BPP data out of a CGImage. I have code that is supposed to put the CGImage into a CGBitmapContext and then give me the data, but it seems to be giving me all black. I've asked a couple of questions today trying to get at this, but I just figured, lets ask the question I REALLY want answered and see if someone can answer it. There's GOT to be a way to do this. I've got to be missing something dumb. What is it?

  • How can I stop an auto-generated Linq to SQL class from loading ALL data?

    - by Gary McGill
    DUPLICATE of http://stackoverflow.com/questions/2433422/how-can-i-stop-an-auto-generated-linq-to-sql-class-from-loading-all-data post answers there! I have an ASP.NET MVC project, much like the NerdDinner tutorial example. (I'm using MVC 2, but followed the NerdDinner tutorial in order to create it). As per the instructions in part 3 of the tutorial, I've created a Linq-to-SQL model of my database by creating a "Linq to SQL Classes" (.dbml) surface, and dropping my database tables onto it. The designer has automatically added relationships between the generated classes based on my database tables. Let's say that my classes are as per the NerdDinner example, so I have Dinner and RSVP tables, where each Dinner record is associated with many RSVP records - hence in the generated classes, the Dinner object has a RSVPs property which is a list of RSVP objects. My problem is this: it appears (and I'd be gladly proved wrong on this) that as soon as I access a Dinner object, it's loading all of the corresponding RSVP objects, even if I don't use the RSVPs member. First question: is this really the default behavior for the generated classes? In my particular situation, the object graph contains many more tables (which have an order of magnitude more records), and so this is disastrous behaviour - I'd be loading tons of data when all I want to do is show the details of a single parent record. Second question: are there any properties exposed through the designer UI that would let me modify this behavior? (I can't find any). Third question: I've seen a description of how to control the loading of related records in a DataContext by using a DataShape object associated with the DataContext. Is that what I'm meant to do, and if so are there any tutorials like the NerdDinner one that would show not only how to do it, but also suggest a 'pattern' for normal use?

First question: is this really the default behavior for the generated classes? In my particular situation, the object graph contains many more tables (which have an order of magnitude more records), and so this is disastrous behaviour - I'd be loading tons of data when all I want to do is show the details of a single parent record. Second question: are there any properties exposed through the designer UI that would let me modify this behavior? (I can't find any). Third question: I've seen a description of how to control the loading of related records in a DataContext by using a DataShape object associated with the DataContext. Is that what I'm meant to do, and if so are there any tutorials like the NerdDinner one that would show not only how to do it, but also suggest a 'pattern' for normal use?

  • Android SQLite database locale, locking, and version

    - by gdoten
    In some books and online I see these method calls being made after a database is created: db.setLocale(Locale.getDefault()); db.setLockingEnabled(true); db.setVersion(DB_VERSION); Why is this done? As far as I can tell, after creating a new database, the system adds a table named android_metadata with one field named locale and that table has one row with the locale field set to "en_US". Now I assume the column has that value because I am using a U.S. phone, and if I were using a phone from a different region then the locale field would be set appropriately. Can anyone confirm this? I'm guessing that the setLocale method would only be useful in the case that you install a pre-built database onto a phone and then want to change the locale to match the phone's locale. Sound right? The documentation for setLockingEnabled says it defaults to true so there's no need to make that call, right? Lastly, what's with the call to setVersion? I can't find a table that contains this information so I've been assuming that the database file itself stores the version number somewhere. So when I create a database, which requires you to have already specified the version number in the call to the SQLiteOpenHelper constructor, there's no point in calling setVersion. Again, perhaps this method exists for the case of installing a pre-built database to a device and you then wish to change the database's version (though I can't think of when doing this would make sense). Thanks for any insight!

  • Why is iPdb not displaying STOUT after my input?

    - by BryanWheelock
    I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program. Below is an example ipdb session, notice how I attempt to display the values of the attributes with: user.is_authenticated() user_profile.reputation user.is_superuser The results are not displayed until 'begin captured stdout ' In [13]: !python manage.py test Creating test database... < SNIP remove loading tables nosetests ...E.. /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or user.is_authenticated() user_profile.reputation user.is_superuser c F /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or c .....EE......

  • Programmatical Creation of NSMappingModel

    - by enchilada
    I want to programmatically (without Lightweight Migration) create a mapping model between two models that are exactly the same, except one of the entities (there are a bunch of entities) has different attributes. Let's call this entity "Person". And let's say the destination model has 1) added a new attribute called "address" 2) deleted an attribute called "eyeColor" 3) kept (i.e. not done anything with) an attribute called "name" How would you create an NSMappingModel between these models programmatically? I happen to have some explicit questions that might help me do this by myself: Q1) Do I have to create NSEntityMapping objects for all of the entities other than "Person", even if they remain unchanged? Q2) How do I deal with the "address" attribute in "Person", which is a new one being created? Should I create an NSPropertyMapping for that somehow, that turns nothing into something ("address")? Q3) How do I deal with the "name" attribute in "Person"? Do I have to create an NSPropertyMapping for that, even though it simply stays the same? Q4) For the NSEntityMapping corresponding to "Person", is not creating any NSPropertyMapping for "eyeColor" a proper way to get it deleted? Or should I create an NSPropertyMapping for "eyeColor"? If yes, how would this object be created, i.e. what would determine that its purpose is to get rid of "eyeColor"? Thank you in advance, and I apologize not being able to answer these questions myself, as the documenation really has no good example of how to create NSMappingModels programmatically. Note again that I'm not allowed to use Lightweight Migration. I must do this manually.

  • TSQL - How to join 1..* from multiple tables in one resultset?

    - by ElHaix
    A location table record has two address id's - mailing and business addressID that refer to an address table. Thus, the address table will contain up to two records for a given addressID. Given a location ID, I need an sproc to return all tbl_Location fields, and all tbl_Address fields in one resultset: LocationID INT, ClientID INT, LocationName NVARCHAR(50), LocationDescription NVARCHAR(50), MailingAddressID INT, BillingAddressID INT, MAddress1 NVARCHAR(255), MAddress2 NVARCHAR(255), MCity NVARCHAR(50), MState NVARCHAR(50), MZip NVARCHAR(10), MCountry CHAR(3), BAddress1 NVARCHAR(255), BAddress2 NVARCHAR(255), BCity NVARCHAR(50), BState NVARCHAR(50), BZip NVARCHAR(10), BCountry CHAR(3) I've started by creating a temp table with the required fields, but am a bit stuck on how to accomplish this. I could do sub-selects for each of the required address fields, but seems a bit messy. I've already got a table-valued-function that accepts an address ID, and returns all fields for that ID, but not sure how to integrate it into my required result. Off hand, it looks like 3 selects to create this table - 1: Location, 2: Mailing address, 3: Billing address. What I'd like to do is just create a view and use that. Any assistance would be helpful. Thanks.

  • Magento resource model for table with compound primary key

    - by sdek
    I am creating a custom module for a Magento ecommerce site, and the module will center around a new (ie, custom) table that has a compound/composite primary key, or rather the table has two columns that make up the primary key. Does anybody know how to create your models/resource models based on a table with a compound key? To give a few more details, I have looked up several tutorials and also used the excellent moduleCreator script. But it seems like all the tutorials revolve around the table having a PK with just one column in it. Something like this: class <Namespace>_<Module>_Model_Mysql4_<Module> extends Mage_Core_Model_Mysql4_Abstract { public function _construct(){ $this->_init('<module_alias>/<table_alias>', '<table_primary_key_id>'); } } Also, I just noticed that looking at the database model almost all tables have a single primary key. I understand this has much to do with the EAV-style db structure, but still is it possible to use a table with a compound PK? I want to stick with the Magento framework/conventions if possible. Is it discouraged? Should I just change the structure of my custom table to have some dummy id column? I do have the ability to do that, but geez! (Another side note that I thought I would mention is that it looks like the Zend Framework provides a way to base a class on a table with compound primary key (see Example #20 on this page - about half-way down), so it seems that the Magento framework should also provide for it... I just don't see how.)
