  • Django date filter: how come the format used is different from the one in datetime library?

    - by sebpiq
    For formatting a date using date filter you must use the following format : {{ my_date|date:"Y-m-d" }} If you use strftime from the standard datetime, you have to use the following : my_date.strftime("%Y-%m-%d") So my question is ... isn't it ugly (I guess it is because of the % that is used also for tags, and therefore is escaped or something) ? But that's not the main question ... I would like to use the same DATE_FORMAT parametrized in settings.py all over the project, but it therefore seems that I cannot ! Is there a work around (for example a filter that removes the % after the date has been formatted like {{ my_date|date|dream_filter }}, because if I just use DATE_FORMAT = "%Y-%m-%d" I got something like %2001-%6-%12)?

  • String Manipulation in Bash

    - by user348000
    Hello- I am a newbie in Bash and I am doing some string manipulation. I have the following file among other files in my directory: jdk-6u20-solaris-i586.sh I am doing the following to get jdk-6u20 in my script: myvar=`ls -la | awk '{print $9}' | egrep "i586" | cut -c1-8` echo $myvar but now I want to convert jdk-6u20 to jdk1.6.0_20. I can't seem to figure out how to do it. It must be as generic as possible. For example if I had jdk-6u25, I should be able to convert it at the same way to jdk1.6.0_25 so on and so forth Any suggestions?

  • Rails: Link changes one attribute and then goes back

    - by James
    Rails newbie here. I have a list of items which can have a status represented by an integer (right now its just 1=active 0=inactive). What I want is next to each item a link to change the status of that item. So it might look like this: A nice item - Enable Another pretty item - Disable I can't think of how to make the link work. I just want a user to click the link and then the page refreshes and the item get updated. This doesn't work: <%= link_to "Enable", :controller => "items", :action => "update", :status => 1 %>

  • How do I get broadcast to work with djcelery+ghettoq

    - by user560833
    I am using djcelery 2.1.4 with ghettoq 0.4.5 and django 1.2.3 and I am able to run tasks all day long, but when I try to use any broadcast functionality it fails without errors. Take the simplest case -- I run celeryd: python manage.py celeryd The daemon starts and I try to run a ping: >>> from celery.task.control import ping >>> ping() [] I can see the message that ping created appear in the database, but apparently none of the nodes are picking it up? Am I doing something wrong here? Does broadcast not work with carrot?

  • Could random.randint(1,10) ever return 11?

    - by Tim Pietzcker
    When researching for this question and reading the sourcecode in random.py, I started wondering whether randrange and randint really behave as "advertised". I am very much inclined to believe so, but the way I read it, randrange is essentially implemented as start + int(random.random()*(stop-start)) (assuming integer values for start and stop), so randrange(1, 10) should return a random number between 1 and 9. randint(start, stop) is calling randrange(start, stop+1), thereby returning a number between 1 and 10. My question is now: If random() were ever to return 1.0, then randint(1,10) would return 11, wouldn't it?

  • iPhone Tab Bar App With Registration View

    - by leeks
    Hi! I'm a relative newbie on iPhone app development but have successfully created a tab bar app with 4 tab bar items.

The registration page should load before the view with the selection of tab bar items loads. What is the best way to do this? Also, how do I load a UIView or UIWebView before the tab bar items load? Any suggestions and sample code would be very much appreciated - thanks!

  • pointers for getting elements of an array in C

    - by Manolo
    I am a newbie in C and I would like to get the elements of an array with a function, I have tried different options, but I still do not get the elements. My function is: void getelements(int *a, int cl) { int *p; for (p=&a[0];p<&a[cl];p++) { printf("%d\n",*p); } } I know that the solution should work like that, but it only prints the first element and then memory positions. I am calling my function with: int v={10,12,20,34,45}; getelements(&v,5); Any help? I need to use arithmetic of pointers. Thanks

  • How do I learn Scheme?

    - by Gautam
    Hey, I'm a relative newbie to programming. I've picked up some very basic Java (File I/O, GUIs, inheritance) and would like to take a look at functional programming - in particular, I would like to learn Scheme. I'm having some trouble finding a Scheme implementation I can understand. Interpreters are weird; I'm not sure how to save my programs and create executables. I've downloaded PLT Scheme, but I would prefer using something less condescending, something similar to NetBeans. Is there a plugin or tool that will allow me to quickly and easily create and manage Scheme programs? All help is appreciated!

  • Rails: What's the suggested approach to retrieve xml from an outside source

    - by Syrahn
    Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

  • TCP Scanner Python MultiThreaded

    - by user1473508
    I'm trying to build a small tcp scanner for a netmask. The code is as follow: import socket,sys,re,struct from socket import * host = sys.argv[1] def RunScanner(host): s = socket(AF_INET, SOCK_STREAM) s.connect((host,80)) s.settimeout(0.1) String = "GET / HTTP/1.0" s.send(String) data = s.recv(1024) if data: print "host: %s have port 80 open"%(host) Slash = re.search("/", str(host)) if Slash : netR,_,Wholemask = host.partition('/') Wholemask = int(Wholemask) netR = struct.unpack("!L",inet_aton(netR))[0] for host in (inet_ntoa(struct.pack("!L", netR+n)) for n in range(0, 1<<32-Wholemask)): try: print "Doing host",host RunScanner(host) except: pass else: RunScanner(host) To launch : python script.py 10.50.23.0/24 The problem I'm having is that even with a ridiculous low settimeout value set, it takes ages to cover the 255 ip addresses since most of them are not assigned to a machine. How can i make a way faster scanner that wont get stuck if the port is close.MultiThreading ? Thanks !

  • What do I put in my Ruby (JRuby) code to break into the debugger?

    - by Daryl Spitzer
    I'm familiarizing myself with some JRuby code, and I'd like to be able to place a breakpoint in the code and run (as usual) from the command-line, having it break into the debugger when it gets to that point. Is there something I can put in my code to force JRuby to break into the debugger? I've tried running jruby -r debug foo.rb (instead of the usual jruby foo.rb), and then setting a breakpoint with b bar.py:98, and then continuing. But the debugger stops every time there's an exception, and there seem to be a lot of them before it gets to the line of code I'm interested in. I'd like to be able to put the "break-into-debugger" line(s) in my code and run jruby foo.rb and have the first place the debugger stops be at that line. (i.e. I'm looking for the Ruby/JRuby equivalent of import pdb;pdb.set_trace() in Python.)

  • How do I point a domain name to a Django url?

    - by username2
    I have a subdomain m.example.com that I want to point to the same location as example.com/mobile running on an apache2/django1.3 installation. example.com is the landing page, and I have the urls.py configured such that urls that match /^mobile$/ will be served the mobile version of the page. I looked into <VirtualHost>, but I think it requires a physical location for me to point m.example.com at and with the django urls there is no physical location except for the root of the project directory. I am unsure if the configuration change is made on the apache side or the django side. I've also looked into the mod_rewrite module for Apache, but I would prefer if I didnt have to redirect m.example.com to example.com/mobile

    I have /path/to/my/theme/static/css/frontend.css which is called by base.html <link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/frontend.css" media="all" /> In which I've got a background for the header: #header-wrapper min-width: 960px; height: 150px; background: transparent url(img/header-bg.png) repeat-x center bottom; } The file is /path/to/my/theme/static/img I've run manage.py collectstatic to gather the files and almost everything looks correct except the link generated looks like: http://example.com/static/css/img/header-bg.png In which the image does not show, because the correct URL is: http://example.com/static/img/header-bg.png Where am I going wrong??

  • Explode URL Query String Issue

    PHP newbie here.. I am trying to create a function where the user is redirected back to the previous page after adding an item to their cart. However, when they are redirected back with the code below it leaves a duplicate of the directory (ie. example.com/catalog/garden-tools/garden-tools function custom_add_to_cart_redirect() { $_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); $url = explode('/', rtrim($_SERVER['REQUEST_URI_PATH'], '/')); return $url[3]; } A print_r reveals the following: Array ( [0] => [1] => thefarmshop [2] => catalog [3] => garden-tools [4] => gardening-glove ) What could the issue be?

  • Rails Routes Mappings

    - by rdasxy
    I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?

    Hello, I have a newbie question about the following: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { NSArray *anArray; anArray = [dictionary objectForKey: [NSString stringWithFormat:@"%d", section]]; //here dictionary is of type NSDictionary, initialized in another place. AnObject *obj = [[AnObject alloc] init]; obj = [anArray objectAtIndex:0]; [anArray release]; return obj.title; } If I run it as it is I will get an error. If I don't put [anArray release] it works just fine. I don't quite understand why is this happening? Thanks.
