    - by Amr ElGarhy

  • How should I use try...except while defining a function?

    - by SpawnCxy
    Hi all, I find I've been confused by the problem that when I needn't to use try..except.For last few days it was used in almost every function I defined which I think maybe a bad practice.For example: class mongodb(object): def getRecords(self,tname,conditions=''): try: col = eval("self.db.%s" %tname) recs = col.find(condition) return recs except Exception,e: #here make some error log with e.message What I thought is ,exceptions may be raised everywhere and I have to use try to get them. And my question is,is it a good practice to use it everywhere when defining functions?If not are there any principles for it?Help would be appreciated! Regards

  • detect a string contained by another discontinuously

    - by SpawnCxy
    Recently I'm working on bad content(such as advertise post) filter of a BBS.And I write a function to detect a string is in another string not continuously.Code as below: $str = 'helloguys'; $substr1 = 'hlu'; $substr2 = 'elf'; function detect($a,$b) //function that detect a in b { $c = ''; for($i=0;$i<=strlen($a);$i++) { for($j=0;$j<=strlen($b);$j++) { if($a[$i] == $b[$j]) { $b=substr($b,$j+1); $c .=$a[$i]; break; } } } if($c == $a) return true; else return false; } var_dump(detect($substr1,$str)); //true var_dump(detect($substr2,$str)); //false Since the filter works before the users do their posts so I think the efficiency here is important.And I wonder if there's any better solution? Thanks!

  • Correct approach to validate attributes of an instance of class

    - by systempuntoout
    Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters declaration ? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

  • Preferred way of filling up a C++ vector of structs

    - by henle
    Alternative 1, reusing a temporary variable: Sticker sticker; sticker.x = x + foreground.x; sticker.y = foreground.y; sticker.width = foreground.width; sticker.height = foreground.height; board.push_back(sticker); sticker.x = x + outline.x; sticker.y = outline.y; sticker.width = outline.width; sticker.height = outline.height; board.push_back(sticker); Alternative 2, scoping the temporary variable: { Sticker sticker; sticker.x = x + foreground.x; sticker.y = foreground.y; sticker.width = foreground.width; sticker.height = foreground.height; board.push_back(sticker); } { Sticker sticker; sticker.x = x + outline.x; sticker.y = outline.y; sticker.width = outline.width; sticker.height = outline.height; board.push_back(sticker); } Alternative 3, writing straight to the vector memory: { board.push_back(Sticker()); Sticker &sticker = board.back(); sticker.x = x + foreground.x; sticker.y = foreground.y; sticker.width = foreground.width; sticker.height = foreground.height; } { board.push_back(Sticker()); Sticker &sticker = board.back(); sticker.x = x + outline.x; sticker.y = outline.y; sticker.width = outline.width; sticker.height = outline.height; } Which approach do you prefer?

  • I'm still learning OOP. Any tips on staying unbiased and pragmatic?

    - by marcdev
    I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

  • BlackBerry - Multiple Screens or Single Screen with Content Manager?

    - by Max Gontar
    Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

  • What are the standard practices for throwing JavasScript Exceptions?

    - by T.R.
    w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)

  • where to place browser event (resize/scroll) detection call

    - by karl
    I'm trying to alert a message when the browser is resized or scrolled. I'm detecting the 2 events in the body <body onResize="doDisp();" onScroll="doDisp();" > where doDisp is this inside the <script> tag <script type="text/javascript"> function doDisp(){ alert("browser changing state"); } </script> but isn't it bad practice to have javascript in the body tag? Is there a cross-browser way to keep all the javascript inside the <script> tags?

  • Best way to integrate searching with pagination

    - by Vijay Choudhary
    I have a web application build on cakephp 2.x. I have integrated pagination on my data. Now i want to implement searching on that data also, and pagination should work according to search result. Now my question is: Should i use a form to post my search string. If so, then which method should i use, GET or POST. OR, should i use javascript window.location method, and append the search string to it. If we use this method then search string can append more than once to url. Or any other best way to implement this. Can anybody give the best solution for this as it is a common task for each application to have.

    - by sc_ray
    I need to work on C++ project on my windows machine. My project will consist of various classes(.h and .cpp) as well as the startup file to start the application.

  • What goes into the "Controller" in "MVC"?

    - by P72endragon
    I think I understand the basic concepts of MVC - the Model contains the data and behaviour of the application, the View is responsible for displaying it to the user and the Controller deals with user input. What I'm uncertain about is exactly what goes in the Controller. Lets say for example I have a fairly simple application (I'm specifically thinking Java, but I suppose the same principles apply elsewhere). I organise my code into 3 packages called app.model, app.view and app.controller. Within the app.model package, I have a few classes that reflect the actual behaviour of the application. These extends Observable and use setChanged() and notifyObservers() to trigger the views to update when appropriate. The app.view package has a class (or several classes for different types of display) that uses javax.swing components to handle the display. Some of these components need to feed back into the Model. If I understand correctly, the View shouldn't have anything to do with the feedback - that should be dealt with by the Controller. So what do I actually put in the Controller? Do I put the public void actionPerformed(ActionEvent e) in the View with just a call to a method in the Controller? If so, should any validation etc be done in the Controller? If so, how do I feedback error messages back to the View - should that go through the Model again, or should the Controller just send it straight back to View? If the validation is done in the View, what do I put in the Controller? Sorry for the long question, I just wanted to document my understanding of the process and hopefully someone can clarify this issue for me!

  • Parent-child table layout

    - by cyberzed
    I'm currently planning a piece of software for dogbreeders and I'm in doubt about my datadesign...whether I'm doing something smart or stupid :) The plan at the moment is one holistic "dog" table sorta like this... Id | Name | FatherId | MotherId ------------------------------- 1 | A | 0 | 0 2 | B | 1 | 0 3 | C | 0 | 0 4 | D | 0 | 3 5 | E | 1 | 3 6 | F | 5 | 2 7 | G | 4 | 3 My questions is, is it common to make it like this or is it really sloppy. I can see a quick lookup reason to have it but I'm really in doubt whether it's good or bad in the end. I thinking it would be better designed if I had a rel-table on the side with Id coupling, but I'm really in doubt how well any of the cases are. A side note is that it'll only be me personally looking at the data this way (or someone adopting the project from me)

  • Throwing special type of exception to terminate unit test

    - by trendl
    Assume I want to write a unit test to test a particular piece of functionality that is implemented within a method. If I wanted to execute the method completely, I would have to do some extra set up work (mock objects expectations etc.). Instead of doing that I use the following approach: - I set up the expectations I'm interested in verifying and then make the tested method throw a special type of exception (e.g. TerminateTestException). - Further down in the unit test I catch the exception and verify the mock object expectations. It works fine but I'm not sure it is good practice. I do not do this regularly, only in cases where it saves me time and effort. One thing that comes to mind as an argument against using this is that throwing exceptions takes long time so the tests execute slower than if I used a different approach.

  • How do you like to define your module-wide variables in drupal 6?

    - by sprugman
    I'm in my module file. I want to define some complex variables for use throughout the module. For simple things, I'm doing this: function mymodule_init() { define('SOME_CONSTANT', 'foo bar'); } But that won't work for more complex structures. Here are some ideas that I've thought of: global: function mymodule_init() { $GLOBALS['mymodule_var'] = array('foo' => 'bar'); } variable_set: function mymodule_init() { variable_set('mymodule_var', array('foo' => 'bar')); } property of a module class: class MyModule { static $var = array('foo' => 'bar'); } Variable_set/_get seems like the most "drupal" way, but I'm drawn toward the class setup. Are there any drawbacks to that? Any other approaches out there?
