  • Is Django's manage.py syncdb or South used to create the test database?

    - by Thierry Lam
    With Django 1.1.1 and South 0.62, running a test from the CLI usually have the following output: Creating table some_model Installing index for my_app.SomeModel model . ----- Ran 1 test in 1s OK After upgrading to South 0.7, the output is invoking South's migration: Creating table some_model Installing index for my_app.SomeModel model Migrating... Running migrations for my_app: - Migrating forwards to 0001_initial > my_app:0001_initial - Loading initial data for my_app Migrated: - my_app . ----- Ran 1 test in 1s OK To create the test DB, has the test always used South migration in the past(before South 0.7) even if the output is not explicitly being shown?

  • Box Shadow on only 3 sides

    - by Connor
    I have two overlapping divs that have css3 box shadows. The trouble is that even when I set the z-index I will still need to eliminate one of the div's box-shadow. I have seen cases where negative spreads and zero values are used but I don't think that would work here. The code I have now is: #bulb-top { position: relative; width: 280px; height: 280px; background-color: #E5F7A3; -webkit-border-radius: 280px; -moz-border-radius: 280px; border-radius: 280px; border: 8px solid #FFF40C; top: -430px; margin-left: auto; margin-right: auto; -webkit-box-shadow: 0px 0px 15px 1px #FFF40C; -moz-box-shadow: 0px 0px 15px 1px #FFF40C; box-shadow: 0px 0px 15px 1px #FFF40C; z-index: 4; } #bulb-bottom { position: relative; width: 140px; height: 120px; background-color: #E5F7A3; -moz-border-radius-topleft: 0px; -moz-border-radius-topright: 0px; -moz-border-radius-bottomright: 30px; -moz-border-radius-bottomleft: 30px; -webkit-border-radius: 0px 0px 30px 30px; border-radius: 0px 0px 30px 30px; border-left: 8px solid #FFF40C; border-right: 8px solid #FFF40C; border-bottom: 8px solid #FFF40C; top: -455px; margin-left: auto; margin-right: auto; -webkit-box-shadow: 0px 0px 15px 1px #FFF40C; -moz-box-shadow: 0px 0px 15px 1px #FFF40C; box-shadow: 0px 0px 15px 1px #FFF40C; z-index: 5; } http://jsfiddle.net/minitech/g42vq/3/

  • How to make a CodeIgniter project portable with redirects

    - by Jono
    I would like to set up my codeigniter projects so I can use it in any folder on my webserver. Unfortunately codeigniter requires me to specify the location in several variables of the config. This is a problem for portability. There are 3 places where I see this: 1) $config['base_url'] 2) $config['base_path'] 3) .htaccess RewriteRule So far, I have found the solution to (1) here: http://codeigniter.com/wiki/Automatic_base_url/ I am looking for solutions to (2) and (3), but most importantly (3). Here is an example situation: I set .htaccess to have the RewriteRule as follows: RewriteRule ^(.*)$ /folderA/index.php/$1 [L] Then I go into my repo and check out the project to another folder to make some separate changes. Now I have to update .htaccess to show the following: RewriteRule ^(.*)$ /folderB/index.php/$1 [L] I would like to set it so I dont have to make any config changes when I check out another copy.

  • WSSQL query for multiple computers at once

    - by Josh
    I can run normal searches just fine. Windows 7 won't let me add a network share to my local index, but I can query the remote index just fine. The problem is that I can't find a way to query two indexes at once. I was hoping that something like this would work: SELECT System.ItemName FROM compA.SystemIndex, compB.SystemIndex WHERE SCOPE='file://compA/pathA' OR SCOPE='file://compB/pathB' but it doesn't. For simple queries, I can query compA and compB separately and then merge the results myself, but I'm hoping for a better way. Anybody here have some experience with this?

  • CodeIgniter's Scaffolding not working

    - by 01010011
    Hi, I keep getting a 404 Page Not Found whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?

  • PHP: session isnt saving before header redirect

    - by Matt
    Hi guys, I have read through the php manual for this problem and it seems quite a common issue but i have yet to find a solution. I am saving sessions in a database. My code is as follows: // session $_SESSION['userID'] = $user->id; header('Location: /subdirectory/index.php'); Then at the top of index.php after the session_start(), i have var_dumped the $_SESSION global and the userID is not in there. As i said ive looked through the PHP manual (http://php.net/manual/en/function.session-write-close.php) and neither session_write_close or session_regenerate_id(true) worked for me. Does anybody know a solution? Edit: I have session_start() at the top of my file. When i var_dump the session global before the header redirect, i see the userID in there, but not in the other file, which is in a subdirectory of this script Thanks, Matt

  • How to check for palindrome using Python logic

    - by DrOnline
    My background is only a 6 month college class in basic C/C++, and I'm trying to convert to Python. I may be talking nonsense, but it seems to me C, at least at my level, is very for-loop intensive. I solve most problems with these loops. And it seems to me the biggest mistake people do when going from C to Python is trying to implement C logic using Python, which makes things run slowly, and it's just not making the most of the language. I see on this website: http://hyperpolyglot.org/scripting (serach for "c-style for", that Python doesn't have C-style for loops. Might be outdated, but I interpret it to mean Python has its own methods for this. I've tried looking around, I can't find much up to date (Python 3) advice for this. How can I solve a palindrome challenge in Python, without using the for loop? I've done this in C in class, but I want to do it in Python, on a personal basis. The problem is from the Euler Project, great site btw. def isPalindrome(n): lst = [int(n) for n in str(n)] l=len(lst) if l==0 || l==1: return True elif len(lst)%2==0: for k in range (l) ##### else: while (k<=((l-1)/2)): if (list[]): ##### for i in range (999, 100, -1): for j in range (999,100, -1): if isPalindrome(i*j): print(i*j) break I'm missing a lot of code here. The five hashes are just reminders for myself. Concrete questions: 1) In C, I would make a for loop comparing index 0 to index max, and then index 0+1 with max-1, until something something. How to best do this in Python? 2) My for loop (in in range (999, 100, -1), is this a bad way to do it in Python? 3) Does anybody have any good advice, or good websites or resources for people in my position? I'm not a programmer, I don't aspire to be one, I just want to learn enough so that when I write my bachelor's degree thesis (electrical engineering), I don't have to simultaneously LEARN an applicable programming language while trying to obtain good results in the project. "How to go from basic C to great application of Python", that sort of thing. 4) Any specific bits of code to make a great solution to this problem would also be appreciated, I need to learn good algorithms.. I am envisioning 3 situations. If the value is zero or single digit, if it is of odd length, and if it is of even length. I was planning to write for loops... PS: The problem is: Find the highest value product of two 3 digit integers that is also a palindrome.

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.

  • Redirect in combination with a rewrite condition in htaccess

    - by Robbert van den Bogerd
    Hi all! I've got a cms-driven website, with no option to change the code. What I want to accomplish is creating friendly url's, using only apaches mod-rewrite engine. The problem is I'm creating an infinite loop, because I first redirect the original url (index.php?id=21) to a friendly one (/friendly/) and then rewrite the '/friendly' part back to 'id=21' I know there should be an extra condition or parameter to avoid looping in this case, but I can´t get one of the possible solutions to work. Here´s the code: RewriteCond %{query_string} ^id=21$ [NC] RewriteRule /* /peuterspeelzaal? [R=301,L] RewriteRule ^peuterspeelzaal$ index.php?id=21 [L]

  • Sanitize a string from ascii art

    - by Toto
    I need to sanitize article titles when (creative) users try to "attract attention" with some bad "ascii art". Exemples: Buy my product !!!!!!!!!!!!!!!!!!!!!!!! Buy my product !? !? !? !? !? !? Buy my product !!!!!!!!!.......!!!!!!!! Buy my product <----------- Some acceptable solution would be to reduce the repetition of non-alphanum to 2. So I would get: Buy my product !! Buy my product !? !? Buy my product !!..!! Buy my product <-- This solution did not work that well: preg_replace('/(\W{2,})(?=\1+)/', '', $title) Any idea how to do it in PHP with regex? Other better solution is also welcomed (I cannot strip all the non-alphanum characters as they can make sense).

  • What's the proper technical term for "high ascii" characters?

    - by moodforaday
    What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope. Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters. What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?

  • Zend Framework command line see errors

    - by sims
    I'm using a method outline by gregor (http://stackoverflow.com/questions/143320/create-cronjob-with-zend-framework) to create command line execution for parts of my application such as cron jobs, admin tasks, and the like. It works, however, no errors get reported when I create a new object that has not been defined (misspelling) and other such mistakes. I would have thought that php would report an error, but it fails silently. What is the reason for this? Is there a better way to achieve my goal? Or how can I implement this so that I can see errors? Many thanks! Here is the code: in public/index.php if(!defined('RUN_APP') || RUN_APP == true) { $application->bootstrap()->run(); } application/cron.php define("RUN_APP",false); require(realpath('/var/www/domain/public/index.php')); $application->bootstrap(); //the rest

  • Ajax Fancy Capture in CakPHP

    - by Constantin.FF
    I have found a nice ajax capture which i would like to use in a CakePHP framework website. The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

  • WordPress: don't show 404 when no posts exist

    - by philfreo
    Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.

  • Suppressing the language select button iPhone

    - by AWinter
    I'm working on an application now that contains an account register section. One field with secureTextEntry = NO (for registering only). The idea is this make registration faster and hopefully increases the number of signups. It's simple enough for me to just place a regular UITextField but if the user has any additional language keyboards then it's possible for the user to enter non-password friendly characters. Unlike in when secureTextEntry = YES. I know I can do textField.keyboardType = UIKeyboardTypeASCIICapable to get the text field to display the ASCII keyboard first, but the user will still have the keyboard switch button which will allow them to get to undesirable characters. Is there a simple method for suppressing the international button or forcing ASCII only keyboard with no international button? [EDIT] Another perhaps better option might be to suppress multi byte keyboards or even to display the text in the case that secureTextEntry = YES any ideas here? [EDIT AGAIN] I've decided it's a really bad idea to suppress the international button as non-multibyte characters should all be allowed.

  • Handling OPTIONS request in nginx

    - by ctmiller
    We're using HAProxy as a load balancer at the moment, and it regularly makes requests to the downstream boxes to make sure they're alive using an OPTIONS request: OPTIONS /index.html HTTP/1.0 I'm working with getting nginx set up as a reverse proxy with caching (using ncache). For some reason, nginx is returning a 405 when an OPTIONS request comes in: 192.168.1.10 - - [22/Oct/2008:16:36:21 -0700] "OPTIONS /index.html HTTP/1.0" 405 325 "-" "-" 192.168.1.10 When hitting the downstream webserver directly, I get a proper 200 response. My question is: how to you make nginx pass that response along to HAProxy, or, how can I set the response in the nginx.conf? Thanks!

  • Unsigned versus signed numbers as indexes

    - by simendsjo
    Whats the rationale for using signed numbers as indexes in .Net? In Python, you can index from the end of an array by sending negative numbers, but this is not the case in .Net. It's not easy for .Net to add such a feature later as it could break other code perhaps using special rules (yeah, a bad idea, but I guess it happens) on indexing. Not that I have ever have needed to index arrays over 2,147,483,647 in size, but I really cannot understand why they choose signed numbers. Can it be because it's more normal to use signed numbers in code?

  • encoding of =1 in emails

    - by Maenny
    Hi folks, I have probably a stupid problem. In a script I generate a URL with GET parameters, something like 'www.mydomain.com/index.php?item=1234'. This URL will be sent by PHP through mail() in an UTF-8 encoding (the scriptfile itself also is utf-8). Now each time I have the GET-Parameter with two numbers after the '=' the URL in the email looks like 'www.mydomain.com/index.php?item?34' with a rectangle instead of '=12'. I am sure there is an easy way to fix this? Thanks in advance, Maenny

  • minimum enclosing rectangle of fixed aspect ratio

    - by Ramya Narasimha
    I have an Image with many rectangles at different positions in the image and of different sizes (both overlapping and non-overlapping). I also have a non-negative scores associated with each of these rectangles. My problem now is to find one larger rectangle *of a fixed (given) aspect ratio* that encloses as many of these rectangles as possible. I am looking for an algorithm to do this, if anyone has a solution, even a partial one it would be helpful. Please note that the positions of the rectangles in the image is fixed and cannot be moved around and there is no orientation issue as all of them are upright.

  • Weird Rails URL issue when rendering a new action

    - by Tony
    I am rendering a new action but somehow getting the "index" URL. To be more specific, my create action looks like this: class ListingsController < ApplicationController def create @listing = Listing.new(params[:listing]) @listing.user = @current_user if @listing.save redirect_to @listing else flash[:error] = "There were errors" render :action => "new" end end end When there are errors, I get the "new" action but my URL is the index URL - http://domain.com/listings Anyone know why this would happen? My routes file is fairly standard: map.connect 'listings/send_message', :controller => 'listings', :action => 'send_message' map.resources :listings map.root :controller => "listings" map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format'
