  • Repeat use of Schema / Rich Snippets Markup i.e LocalBusiness Data

    - by bybe
    I am unable to find official wording and I'm hoping that some Rich Snippets/Schema Guru can give me some insight into proper usage of repeated content when it comes to using markup. I'm building a site that wants to use Schema as the markup type and the owner would like as much usage as possible. The business name, telephone and address will appear on every page now is it valid or even useful to use Rich Snippets on every page where this information is displayed. For example this information appears in the header, and footer of every page of the site and too give you an example of my current markup see below: <body itemscope itemtype="http://schema.org/LocalBusiness"> <header> <a itemprop="url" href="http://www.domain.co.uk/"> <img itemprop="logo" src="image.png" alt="Company Name Logo" /> </a> <span itemprop="telephone">01202 000 000</span> </header> <div> This is where the content will go</div> <footer> <span itemprop="name">Company Name</span> <span itemprop="description"> A small little bit about this company</span> <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <span itemprop="streetAddress">Address Goes here</span> <span itemprop="addressLocality">Area Here</span>, <span itemprop="addressRegion">Region Here</span> </div> </footer> </body> !-- Local Business Schema Now Closed --> So as you can see above this information will be displayed on every single page.... Is this valid or bad to repeat usage of this information in schema format...

  • What is logical cohesion, and why is it bad or undesirable?

    - by Matt Fenwick
    From the c2wiki page on coupling & cohesion: Cohesion (interdependency within module) strength/level names : (from worse to better, high cohesion is good) Coincidental Cohesion : (Worst) Module elements are unrelated Logical Cohesion : Elements perform similar activities as selected from outside module, i.e. by a flag that selects operation to perform (see also CommandObject). i.e. body of function is one huge if-else/switch on operation flag Temporal Cohesion : operations related only by general time performed (i.e. initialization() or FatalErrorShutdown?()) Procedural Cohesion : Elements involved in different but sequential activities, each on different data (usually could be trivially split into multiple modules along linear sequence boundaries) Communicational Cohesion : unrelated operations except need same data or input Sequential Cohesion : operations on same data in significant order; output from one function is input to next (pipeline) Informational Cohesion: a module performs a number of actions, each with its own entry point, with independent code for each action, all performed on the same data structure. Essentially an implementation of an abstract data type. i.e. define structure of sales_region_table and its operators: init_table(), update_table(), print_table() Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion. My questions are: what is logical cohesion? Why does it get such a bad rap (2nd worst kind of cohesion)?

  • running adb via wifi on ubuntu 13.04

    - by Blaze Tama
    First, im new on linux so please bear with me. I have a rooted android phone and i was able to run the adb via wifi network on windows, where i just need to go to the adb's directory and type adb connect. However, i can't just do that in my ubuntu. Everytime i enter adb connect, the terminal always said that i dont have the adb and i must install it. When i check the ADT Bundle (I downloaded the bundled one from here), i can see the adb is there inside the platform-tools folder. I already tried to change the directory to the platform-tools and run the adb connect from there, but its still not working. Do i need to install the adb again via terminal? Or did i miss something? You may be wondering why dont i just download the adb (again) via terminal and do trial and error? The answer is because i dont have a good internet connection, so i want to avoid unnecessary downloads. Thanks for your time :D

  • Static DataTable or DataSet in a class - bad idea?

    - by Superbest
    I have several instances of a class. Each instance stores data in a common database. So, I thought "I'll make the DataTable table field static, that way every instance can just add/modify rows to its own table field, but all the data will actually be in one place!" However, apparently it's a bad idea to do use static fields, especially if it's databases: Don't Use "Static" in C#? Is this a bad idea? Will I run into problems later on if I use it? This is a small project so I can accept no testing as a compromise if that is the only drawback. The benefit of using a static database is that there can be many objects of type MyClass, but only one table they all talk to, so a static field seems to be an implementation of exactly this, while keeping syntax concise. I don't see why I shouldn't use a static field (although I wouldn't really know) but if I had to, the best alternative I can think of is creating one DataTable, and passing a reference to it when creating each instance of MyClass, perhaps as a constructor parameter. But is this really an improvement? It seems less intuitive than a static field.

  • C++ Windows Forms application unhandled exception error when textbox empty

    - by cmorris1441
    I'm building a temperature conversion application in Visual Studio for a C++ course. It's a Windows Forms application and the code that I've written is below. There's other code to of course, but I'm not sure you need it to help me. My problem is, when I run the application if I don't have anything entered into either the txtFahrenheit or txtCelsius2 textboxes I get the following error: "An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll" The application only works right now when a number is entered into both of the textboxes. I was told to try and use this: Double::TryParse() but I'm brand new to C++ and can't figure out how to use it, even after checking the MSDN library. Here's my code: private: System::Void btnFtoC_Click(System::Object^ sender, System::EventArgs^ e) { // Convert the input in the Fahrenheit textbox to a double datatype named fahrenheit for manipulation double fahrenheit = Convert::ToDouble(txtFahrenheit->Text); // Set the result string to F * (5/9) -32 double result = fahrenheit * .5556 - 32; // Set the Celsius text box to display the result string txtCelsius->Text = result.ToString(); } private: System::Void btnCtoF_Click(System::Object^ sender, System::EventArgs^ e) { // Convert the input in the Celsius textbox to a double datatype name celsius for manipulation double celsius = Convert::ToDouble(txtCelsius2->Text); // Set the result2 string to C * (9/5) + 32 double result2 = celsius * 1.8 + 32; // Set the Fahrenheit text box to display the result2 string txtFahrenheit2->Text = result2.ToString(); }

  • How to install Ubuntu 12.04.1 in EFI mode with Encrypted LVM?

    - by g0lem
    I'm trying to properly install Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with the alternate install CD ".iso" on a lenovo Thinkpad X220. Default Hard Disk (with a pre-installed version of Windows 7) has been replaced with a brand new SSD. The UEFI BIOS of the lenovo Thinkpad X220 is set to "UEFI Boot only" & "USB UEFI BIOS Support" is enabled (I'm using an external USB DVD reader to perform Ubuntu installation). The BIOS is a Phoenix SecureCore Tiano, BIOS version is 8DET56WW (1.26). The attempts below are made with the UEFI BIOS settings described above. Here's what I've tried so far: Boot on a live GParted CD Create a GPT partition table Create a FAT32 partition for UEFI System, set the partition to "EF00" type ("boot" flag) Leave remaining space unformated Boot on Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with alternate CD: Perform the install with network updates enabled Use manual partitioning FAT32 partition created with GParted is used as "EFI System partition" Remaining space is set to be used as "Physical volume for LVM" Then "Configure encrypted volumes" using the previous "Physical volume for LVM" as the encrypted container, passphrase is setup. "Configure the Logical Volume Manager" creating a volume Group using the encrypted container /dev/mapper/sda2_crypt Creation of the Logical Volumes "Create logical volume", choosing the previously created volume Group Assign a mount point and file system to the Logical volumes : LV-root for / LV-var for /var LV-usr for /usr LV-usr-local for /usr/local LV-swap for swap LV-home for /home NOTE: /tmp would be in RAM only using TMPFS Bootloader step: neither my ESP partition (/dev/sda1, /dev/sda or MBR) seems to be the right place for GRUB, I get the following message (X suffix is for demonstration only): unable to install grub in /dev/sdaX Executing 'grub-install /dev/sdaX' failed This is a fatal error. Finish installation without the Bootloader & Reboot The system doesn't start, there's no EFI/GRUB menu at startup. What are the steps to perform a clean and working installation of Ubuntu 12.04.1 Precise Pangolin, 64bit version in U(EFI) mode using the encrypted LUKS + LVM scheme described above?

  • How bad is it to have two methods with the same name but different signatures in two classes?

    - by Super User
    I have a design problem related to a public interface, the names of methods, and the understanding of my API and code. I have two classes like this: class A: ... function collision(self): .... ... class B: .... function _collision(self, another_object, l, r, t, b): .... The first class has one public method named collision, and the second has one private method called _collision. The two methods differs in argument type and number. As an example let's say that _collision checks if the object is colliding with another object with certain conditions l, r, t, b (collide on the left side, right side, etc) and returns true or false. The public collision method, on the other hand, resolves all the collisions of the object with other objects. The two methods have the same name because I think it's better to avoid overloading the design with different names for methods that do almost the same thing, but in distinct contexts and classes. Is this clear enough to the reader or I should change the method's name?

  • Object oriented wrapper around a dll

    - by Tom Davies
    So, I'm writing a C# managed wrapper around a native dll. The dll contains several hundred functions. In most cases, the first argument to each function is an opaque handle to a type internal to the dll. So, an obvious starting point for defining some classes in the wrapper would be to define classes corresponding to each of these opaque types, with each instance holding and managing the opaque handle (passed to its constructor) Things are a little awkward when dealing with callbacks from the dll. Naturally, the callback handlers in my wrapper have to be static, but the callbacks arguments invariable contain an opaque handle. In order to get from the static callback back to an object instance, I've created a static dictionary in each class, associating handles with class instances. In the constructor of each class, an entry is put into the dictionary, and this entry is then removed in the Destructors. When I receive a callback, I can then consult the dictionary to retrieve the class instance corresponding to the opaque reference. Are there any obvious flaws to this? Something that seems to be a problem is that the existence static dictionary means that the garbage collector will not act on my class instances that are otherwise unreachable. As they are never garbage collected, they never get removed from the dictionary, so the dictionary grows. It seems I might have to manually dispose of my objects, which is something absolutely would like to avoid. Can anyone suggest a good design that allows me to avoid having to do this?

  • How can I get nvidia-96 installed?

    - by Bob
    I'm at my wits end here. This is my last effort before I go back to Windows. I need to get nvidia-96 proprietary driver installed. Synaptic won't install it because it says it has dependencies. I installed every single dependency it listed except for "xorg-video-abi-10" which does not show up as an item that can be installed. I have no idea what to do. Using 11.10 with a NVIDIA Geforce 3 GPU. Anyone know how to get this dang driver installed? @fossfreedom: the opensource driver is extremely slow. So slow that the OS is unusable—words appear seconds after I type them—programs take forever to perform actions. Also it is causing my monitor to turn on and off for no reason. @yossile: synaptic shows that I have xserver-xorg-core installed. And xserver-xorg-core-udeb does not show up as something that can be installed. @papseddy: when I try to install the downloaded nvidia driver it says it won't work until I disable Nouveau kernel driver. I have tried everything to get this dang Nouveau kernel driver disabled. Nothing has been successful.

  • Saving Dragged Dropped items position on postback in asp.net [closed]

    - by Deeptechtons
    Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

  • Stacks in C++

    - by MarkPearl
    So some more basics… One of the things you will be taught at any college after conquering arrays is different derivatives of collections. Stack is one of the simplest of those and very useful… A stack is a LIFO (last in first out) data structure and has at least two basic method calls – push & pop. Push, “pushes” an item on the top of the stack. Pop, removes the top most item off the stack. Because all elements on a stack are of the same type, one can use an array to implement a stack or a linked list. With the array based approach, the first element in a stack would be the first element in the array, the second on the stack would be the second on the array, etc. One limitation with an array implementation of a stack is that unless the array is dynamic, one would have to have a preset max stack size (based on the bounds of the array). Linked lists is another approach that gets past this boundary by allowing you to dynamically grow or shrink a collection of data. Stacks have many applications… a typical computer science example would be Postfix Expression Calculator, where the LIFO principle is maintained.

  • Why can't I compare two Texture2D's?

    - by Fiona
    I am trying to use an accessor, as it seems to me that that is the only way to accomplish what I want to do. Here is my code: Game1.cs public class GroundTexture { private Texture2D dirt; public Texture2D Dirt { get { return dirt; } set { dirt = value; } } } public class Main : Game { public static Texture2D texture = tile.Texture; GroundTexture groundTexture = new GroundTexture(); public static Texture2D dirt; protected override void LoadContent() { Tile tile = (Tile)currentLevel.GetTile(20, 20); dirt = Content.Load<Texture2D>("Dirt"); groundTexture.Dirt = dirt; Texture2D texture = tile.Texture; } protected override void Update(GameTime gameTime) { if (texture == groundTexture.Dirt) { player.TileCollision(groundBounds); } base.Update(gameTime); } } I removed irrelevant information from the LoadContent and Update functions. On the following line: if (texture == groundTexture.Dirt) I am getting the error Operator '==' cannot be applied to operands of type 'Microsoft.Xna.Framework.Graphics.Texture2D' and 'Game1.GroundTexture' Am I using the accessor correctly? And why do I get this error? "Dirt" is Texture2D, so they should be comparable. This using a few functions from a program called Realm Factory, which is a tile editor. The numbers "20, 20" are just a sample of the level I made below: tile.Texture returns the sprite, which here is the content item Dirt.png Thank you very much! (I posted this on the main Stackoverflow site, but after several days didn't get a response. Since it has to do mainly with Texture2D, I figured I'd ask here.)

    Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page. Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11. The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type. You can migrate guest domain from a system with UltraSPARC  T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system. For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and  Cross CPU Migration refer to the following white paper

  • CUDA & MSI GT60 with Optimus enabled GTX670M?

    - by user1076693
    I have a MSI GT60 Laptop with an Optimus enabled GTX 670M GPU, and I have been trying to get CUDA going in Ubuntu 12.04 environment. I realize that Optimus is not supported in Linux, but I have read the following post suggesting that CUDA works for hybrid GPUs. How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? I installed the NVIDIA driver via sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current The resulting driver version is 302.17, and supposedly GTX 670M is supported since 295.59. I also downloaded CUDA 4.2 from the NVIDIA site, and compiled it against nvidia-current libraries. Unfortunately, when I run deviceQuery in the CUDA SDK, I get the following output cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected Checking /proc/driver/nvidia/gpus/0/information gives the following Model: GeForce GTX 670M IRQ: 16 GPU UUID: GPU-????????-????-????-????-???????????? Video BIOS: ??.??.??.??.?? Bus Type: PCI-E DMA Size: 32 bits DMA Mask: 0xffffffffff Bus Location: 0000:01.00.0 Here is the output of "lspci | grep VGA" 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1213 (rev ff) So... what am I doing wrong? Thanks!

  • Data base structure of a subscriber list

    - by foodil
    I am building a application that allow different user to store the subscriber information To store the subscriber information , the user first create a list For each list, there is a ListID. Subscriber may have different attribute : email phone fax .... For each list, their setting is different , so a require_attribute table is introduced. It is a bridge between subscriber and List That store Listid ,subid , attribute, datatype That means the system have a lot of list, each user have their own list, and the list have different attribute, some list have email , phone , some may have phone, address, name mail.. And the datatype is different, some may use 'name' as integer , some may use 'name' as varchar attribute means email phone, it is to define for which list have which subscriber attribute datatype means for each attribute, what is its datatype Table :subscriber : Field :subid , name,email Table :Require Attribute: Field : Listid ,subid , attribute, datatype The attribute here is {name, email} So a simple data is Subscriber: 1 , MYname, Myemail Require Attribute : Listid , 1 , 'email', 'intger' Listid , 1 , 'name', 'varchar' I found that this kind of storage is too complex too handle with, Since the subscriber is share to every body, so if a person want to change the datatype of name, it will also affect the data of the other user. Simple error situation: Subscriber: list1, Subscriber 1 , name1, email1 list2, Subscriber 2 , name2 , email2 Require Attribute : List1 , Subscriber 1 , 'email', 'varchar', List1 , Subscriber 1 , 'name', 'varchar', Listid , Subscriber 2 , 'email', 'varchar', Listid , Subscriber 2, 'name', 'integer', if user B change the data type of name in require attribute from varchar to integer, it cause a problem. becasue list 1 is own by user A , he want the datatype is varchar, but list 2 is won by user B , he want the datatype to be integer So how can i redesign the structure?

  • Collision checking problem on a Tiled map

    - by nosferat
    I'm working on a pacman styled dungeon crawler, using the free oryx sprites. I've created the map using Tiled, separating the floor, walls and treasure in three different layers. After importing the map in libGDX, it renders fine. I also added the player character, for now it just moves into one direction, the player cannot control it yet. I wanted to add collision and I was planning to do this by checking if the player's new position is on a wall tile. Therefore as you can see in the following code snippet, I get the tile type of the appropriate tile and if it is not zero (since on that layer there is nothing except the wall tile) it is a collision and the player cannot move further: final Vector2 newPos = charController.move(warrior.getX(), warrior.getY()); if(!collided(newPos)) { warrior.setPosition(newPos.x, newPos.y); warrior.flip(charController.flipX(), charController.flipY()); } [..] private boolean collided(Vector2 newPos) { int row = (int) Math.floor((newPos.x / 32)); int col = (int) Math.floor((newPos.y / 32)); int tileType = tiledMap.layers.get(1).tiles[row][col]; if (tileType == 0) { return false; } return true; } The character only moves one tile with this code: If I reduce the col value by two it two more tiles. I think the problem will be around indexing, but I'm totally confused because the zero in the coordinate system of libGDX is in the bottom left corner of the screen, and I don't know the tiles array's indexing is similair or not. The size of the map is 19x21 tiles and looks like the following (the starting position of the player is marked with blue:

  • Service layer coupling

    - by Justin
    I am working on writing a service layer for an order system in php. It's the typical scenario, you have an Order that can have multiple Line Items. So lets say a request is received to store a line item with pictures and comments. I might receive a json request such as { 'type': 'Bike', 'color': 'Red', 'commentIds': [3193,3194] 'attachmentIds': [123,413] } My idea was to have a Service_LineItem_Bike class that knows how to take the json data and store an entity for a bike. My question is, the Service_LineItem class now needs to fetch comments and file attachments, and store the relationships. Service_LineItem seems like it should interact with a Service_Comment and a Service_FileUpload. Should instances of these two other services be instantiated and passed to the Service_LineItem constructor,or set by getters and setters? Dependency injection seems like the right solution, allowing a service access to a 'service fetching helper' seems wrong, and this should stay at the application level. I am using Doctrine 2 as a ORM, and I can technically write a dql query inside Service_LineItem to fetch the comments and file uploads necessary for the association, but this seems like it would have a tighter coupling, rather then leaving this up to the right service object.

  • How do I get my programs to communicate with each other

    - by Benjamin Lindqvist
    I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

  • How do I modify these VPN connection settings for Xfce?

    - by Dave M G
    I have signed up for a VPN (Virtual Private Network) service, and I configured it for use on my computer that runs Gnome Classic with the following instructions: In Terminal, install openvpn packages with sudo apt-get install network-manager-openvpn. 1. Restart the network manager with sudo restart network-manager 2. Run sudo wget https://www.xxxxxxx.com/ovpnconfigure.zip 3. Extract the files from the zip with unzip ovpnconfigure.zip. 4. Move cert.crt to /etc/openvpn 5. Open the Network Manager on the menu bar. 6. Choose add and select the OpenVPN connection type, and click Create. 7. Enter Private Internet Access SSL for the Connection Name. 8. Enter xxxxxx.xxxxxxxx.com for the Gateway 9. Select Password and enter your login credentials. 10. Browse and select the CA Certificate we saved in Step 3. 11. Choose Advanced and enable LZO Compression. 12. Apply and exit. 13. Connect using the Network Manager. It worked, but now I want to set up access to the same VPN service on another machine that runs Mythbuntu, which uses Xfce as its desktop manager. So every point from 5 on doesn't apply. How can I modify the above instructions so that I can get my VPN service working with Xfce. As a further note, while I can access the Xfce desktop directly if I need to, it's more convenient for me to access it via the command line and SSH from on of my other computers. A command line process would be ideal. (I looked for this, and found instructions only for PPTP access, whereas I need OpenVPN.)

  • The Importance of Fully Specifying a Problem

    - by Alan
    I had a customer call this week where we were provided a forced crashdump and asked to determine why the system was hung. Normally when you are looking at a hung system, you will find a lot of threads blocked on various locks, and most likely very little actually running on the system (unless it's threads spinning on busy wait type locks). This vmcore showed none of that. In fact we were seeing hundreds of threads actively on cpu in the second before the dump was forced. This prompted the question back to the customer: What exactly were you seeing that made you believe that the system was hung? It took a few days to get a response, but the response that I got back was that they were not able to ssh into the system and when they tried to login to the console, they got the login prompt, but after typing "root" and hitting return, the console was no longer responsive. This description puts a whole new light on the "hang". You immediately start thinking "name services". Looking at the crashdump, yes the sshds are all in door calls to nscd, and nscd is idle waiting on responses from the network. Looking at the connections I see a lot of connections to the secure ldap port in CLOSE_WAIT, but more interestingly I am seeing a few connections over the non-secure ldap port to a different LDAP server just sitting open. My feeling at this point is that we have an either non-responding LDAP server, or one that is responding slowly, the resolution being to investigate that server. Moral When you log a service ticket for a "system hang", it's great to get the forced crashdump first up, but it's even better to get a description of what you observed to make to believe that the system was hung.

  • Parameterized Django models

    - by mgibsonbr
    In principle, a single Django application can be reused in two or more projects, providing functionality relevent to both. That implies that the same database structure (tables and relations) will be re-created identically in different databases, and most times this is not a problem (assuming the projects/databases are unrelated - for instance when someone downloads a complete app to use in their own projects). Sometimes, however, the models must be "tweaked" a little to better fit the problem needs. This can be accomplished by forking the app, but I wondered if there wouldn't be a better option in cases where the app designer can anticipate the most common customizations. For instance, if I have a model that could relate to another as one-to-one or one-to-many, I could specify the unique property as a parameter, that can be specified in the project's settings: class This(models.Model): other = models.ForeignKey(Other, unique=settings.OTHER_TO_THIS) Or if a model can relate to many others, I could create an intermediate table for each of them (thus enforcing referential integrity) instead of using generic fks: for related in settings.MODELS_RELATED_TO_OTHER: model_name = '%s_Other' % related globals()[model_name] = type(model_name, (models.Model,) { me:models.ForeignKey(find_model_class(related)), other:models.ForeignKey(Other), # Some other properties all intersection tables must have }) Etc. Let me stress out that I'm not proposing to change the models at runtime nor anything like that; once the parameters were defined and syncdb called for the first time, those parameters are not to be changed again (unless you're doing a schema migration). Is this a good design? Are there better ways to accomplish the same thing, or maybe drawbacks I coulnd't anticipate? This technique is meant to be used sparingly (only on apps meant to be reused in wildly different contexts, and only when a specific need of customization can be detected while the app model is being designed).
