  • How to cutomize a modelform widget in django 1.1?

    - by muudscope
    I'm trying to modify a django form to use a textarea instead of a normal input for the "address" field in my house form. The docs seem to imply this changed from django 1.1 (which I'm using) to 1.2. But neither approach is working for me. Here's what I've tried: class HouseForm(forms.ModelForm): address = forms.Textarea() # Should work with django 1.1, but doesn't class Meta: model = House #widgets = { 'address': forms.Textarea() } # 1.2 style - doesn't work either.

  • OpenGL: Implementing transformation matrix stack

    - by Jakub M.
    In a newer OpenGL there is no matrix stack. I am working on a simple display engine, and I am going to implement the transformation stack. What is a common strategy here? Should I build a push/pop stack, and use it with a tree representing my model? I suppose this is the "old" approach, that was deprecated in the newer OpenGL versions. Maybe then it is not the best solution (it was removed for some reason)

  • IBOutlet on properties and exposition of the class

    - by Espuz
    Apple, for memory management issues, recommend defining outlets on properties, not in the attribute declaration. But, as far as I know, declaring properties exposes the class to external classes, so this could be dangerous. On UIViewController we have the main view definition and the logic, so MVC is slightly cheated in this cases. What is the beteer approach, Apples's recommendation for memory-management or armored classes?

  • Linq to SQL - Returning two values with one query

    - by Sir Psycho
    Hi, Is it possible to return a single value and an enumerable collection using LINQ to SQL? The problem is, I'm trying to do paging across a large recordset. I only want to return 10 rows at a time so I'm using .Skip(20).Take(10) approach. However I need to know the total number of records so I can show an appropriate page x of y. Trying to avoid two separate queries. Thanks

  • How does your team handle support requests

    - by Skeep
    Hi All, I have just taken over as manager at a company and at the moment they are very rigid in how they approach development. Everyone gets a list of what they are doing each week. My question is how does your company balance support with development and if an important support request comes in how is this processed without disturbing the flow of the developers? Lastly, do you use an software log support requests and development tasks. Thanks

  • How to create a horizontal scrollable list?

    - by Thomas Joos
    hi all, I am wondering what the best approach is for creating a horizontal list with custom buttons. I read there is no native control for that: I am considering a UIView with a scroll view inside. On this scrollview I visualize my array of button objects. Any thoughts?

  • How to get width of button in DateTimePicker-Control/Controls in general?

    - by Inno
    Hello everybody, I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

  • Entity Framework 4 POCO with Dictionary

  • Creating content input form with custom theme (Drupal)

    - by AndrewSmith
    I'm creating a site which I want to place content input form in custom themed template. I opted to do this because I wanted the whole site to be looked uniform. That said, I'm not sure as to what is the best approach to do this. Is it proper to invoke hook_insert/delete/update and hook_perm/hook_access by myself or is there anyway I can still use my custom theme and write a code in a way that drupal would take care of invoking appropriate hooks accordingly? Thanks in advance PS : I'm on drupal 6.x

  • How to improve variable overriding/overwriting in XSL?

    - by ChrisBenyamin
    I want to do the following: Declare a variable Go into a if-statement Overwrite the variable XSL says I can't declare a variable twice, so what can I do to improve this step? Another approach was to check if a variable is set at all. I did this, because i skipped the first step and declared the variable in the if-statement. In another if-statement I wanted to check if the variable exists at all.

  • How to pass operators as parameters

    - by Rodion Ingles
    I have to load an array of doubles from a file, multiply each element by a value in a table (different values for different elements), do some work on it, invert the multiplication (that is, divide) and then save the data back to file. Currently I implement the multiplication and division process in two separate methods. Now there is some extra work behind the scenes but apart from the specific statements where the multiplication/division occurs, the rest of the code is identical. As you can imagine, with this approach you have to be very careful making any changes. The surrounding code is not trivial, so its either a case of manually editing each method or copying changes from one method to the other and remembering to change the * and / operators. After too many close calls I am fed up of this and would like to make a common function which implements the common logic and two wrapper functions which pass which operator to use as a parameter. My initial approach was to use function pointers: MultiplyData(double data) { TransformData(data, &(operator *)); } DivideData(double data) { TransformData(data, &(operator /)); } TransformData(double data, double (*func)(double op1, double op2)) { /* Do stuff here... */ } However, I can't pass the operators as pointers (is this because it is an operator on a native type?), so I tried to use function objects. Initially I thought that multiplies and divides functors in <functional> would be ideal: MultiplyData(double data) { std::multiplies<double> multFunct; TransformData(data, &multFunct); } DivideData(double data) { std::divides<double> divFunct; TransformData(data, &divFunct); } TransformData(double data, std::binary_function<double, double, double> *funct) { /* Do stuff here... */ } As you can see I was trying to use a base class pointer to pass the functor polymorphically. The problem is that std::binary_function does not declare an operator() member for the child classes to implement. Is there something I am missing, or is the solution to implement my own functor heirarchy (which really seems more trouble than it is worth)?

  • URL Controller Mapping Strategies (PHP)

    - by sunwukung
    This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one: http://stackoverflow.com/questions/125677/php-application-url-routing So far, I can ascertain two practices: 1: dynamic mapping through parsing the URL string (exploded on '/') 2: pattern matching matching url to config file containing available routes I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.

  • Dynamically Rendering in a Scrollable Area

    - by James
    What is the generic algorithm or process that is commonly used to dynamically render portions of a scrolling area? For example, in Google Maps, when the user scrolls past the bounds of the currently rendered area, a grey checkerboard pattern is displayed within the not-yet-rendered portions while the application loads and renders those areas. I'm looking specifically for the approach, or the mathematics, related to filling a graphics area in chunks based on what has just come into view. If possible, I'm looking for anything relevant to the GDI+ process of doing so.

  • sed - trying to replace first occurrence after a match

    - by wakkaluba
    I am facing a situation that drives me nuts. I am setting up an update server which uses a json file. Don't ask why or how, it sucks and is my only possibility to achieve it. I have been trying and researching for HOURS (many) because I went ballistic and wanted to crack this on my own. But I have to realize I got stuck and need help. So sorry for this chunk but I think it is somewhat important to see... The file is a one liner and repeating the following sequence with changing values (of course). "plugin_name_foo_bar": {"buildDate": "bla", "dependencies": [{"name": "bla", "optional": true, "version": "1.00"}], "developers": [{"developerId": "bla", "email": "[email protected]", "name": "Bla bla2nd"}], "excerpt": "some text {excerpt} !bla.png|thumbnail,border=1! ", "gav": "bla", "labels": ["report", "scm-related"], "name": "plugin_name_foo_bar", "previousTimestamp": "bla", "previousVersion": "1.0", "releaseTimestamp": "bla", "requiredCore": "1", "scm": "github.com", "sha1": "ynnBM2jWo25ZLDdP3ybBOnV/Pio=", "title": "bla", "url": "http://bla.org", "version": "1.0", "wiki": "https://bla.org"}, "Exclusion": {"buildDate": "bla", "dependencies": [], and the next plugin block is glued straight afterwards. What I now want to do is to search for "plugin_foo_bar": {" as this is the unique identifier for a new plugin description block. I want to replace the first sha1 value occuring afterwards. That's where I keep failing. I always grab the first,last or any occurrence in the entire file and not the block :( "title" is the unique identifier after the sha1 value. So I tried to make the .* less greedy but it ain't working out. last attempt was heading towards: sed -i 's/("name": "plugin_name_foo_bar.*sha1": ")([a-zA-Z0-9!@#\$%^&*()\[\]]*)(", "title"\)/\1blablabla\2/1' default.json to find the sha1 value of that plugin but still no joy. I hope someone knows - preferably a simpler approach - before I now continue with trial and error until I have to puke and freakout. I am working with SED on Windows, so Unix approach might help me to figure out how to achieve this in batch but please make it as one-liner if possible. Scripts are a real pain to convert. And I just need SED and no other solution with other tools like AWK. That is absolutely out of discussion. Any help is appreciated :) Cheers Jan

  • Django: What's the correct way to get the requesting IP address?

    - by swisstony
    I'm trying to develop an app using Django 1.1 on Webfaction. I'd like to get the IP address of the incoming request, but when I use request.META['REMOTE_ADDR'] it returns 127.0.0.1. There seems to be a number of different ways of getting the address, such as using HTTP_X_FORWARDED_FOR or plugging in some middleware called SetRemoteAddrFromForwardedFor. Just wondering what the best approach was?
