  • Changing models in django results in broken database?

    - by Rhubarb
    I have added and removed fields in my models.py file and then run manage.py syncdb. Usually I have to quit out of the shell and restart it before syncdb does anything. And then even after that, I am getting errors when trying to access the admin pages, it seems that certain new fields that I've added still don't show up in the model: Caught an exception while rendering: no such column: mySite_book.Title

  • Uploading a picture to facebook

    - by kielie
    Hi guys, I am trying to upload a image to a gallery on a facebook fan page, here is my code thus far, $ch = curl_init(); $data = array('type' => 'client_cred', 'client_id' => 'app_id','client_secret'=>'secret_key',' redirect_uri'=>'http://apps.facebook.com/my-application/'); // your connect url here curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/oauth/access_token'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $rs = curl_exec($ch); curl_close($ch); $ch = curl_init(); $data = explode("=",$rs); $token = $data[1]; $album_id = '1234'; $file= 'http://my.website.com/my-application/sketch.jpg'; $data = array(basename($file) => "@".realpath($file), //filename, where $row['file_location'] is a file hosted on my server "caption" => "test", "aid" => $album_id, //valid aid, as demonstrated above "access_token" => $token ); $ch2 = curl_init(); $url = "https://graph.facebook.com/".$album_id."/photos"; curl_setopt($ch2, CURLOPT_URL, $url); curl_setopt($ch2, CURLOPT_HEADER, false); curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch2, CURLOPT_RETURNTRANSFER, false); curl_setopt($ch2, CURLOPT_POST, true); curl_setopt($ch2, CURLOPT_POSTFIELDS, $data); $op = curl_exec($ch2); When I echo $token, I seem to be getting the token, but when I run the script, I get this error, {"error":{"type":"OAuthAccessTokenException","message":"An access token is required to request this resource."} , I have NO idea why it is doing this! Basically what I am doing in that code is getting the access token with curl, and then, uploading the photo to my album also via curl, but I keep getting that error! Any help would be appreciated, thank you!

  • "Fix" String encoding in Java

    - by Nico
    I have a String created from a byte[] array, using UTF8 encoding. However, it should have been created using another encoding (windows-1252). Is there a way to convert this string back to the right encoding? I know it's easy to do if you have access to the original byte array, but it my case it's too late because it's given by a closed source library. Thanks, Nico

  • IntelliJ IDEA "Tomcat manager" application

    - by Jon
    Hello, I'm using IntelliJ IDEA 9.0.2 but I assume this question applies to previous versions as well. In the Run/Debug Configurations dialog there is an option called "Deploy 'Tomcat Manager' application", but I haven't been able to find any documentation for how to use it in the IntelliJ help or online. Has anyone had experience using this, and know what URL I could use to access it once Tomcat is running? Thanks!

    - by Nirmal
    Say if I register a domain and have developed it into a complete website. From where and how Googlebot knows that the new domain is up? Does it always start with the domain registry? If it starts with the registry, does that mean that anyone can have complete access to the registry's database? Thanks for any insight.

  • libpcap packet size

    - by silverbandit91
    I'm working with libpcap in C on linux (centos) and I'm following this guide I want to simply print out the entire packet in ascii and i'v managed to get it working by casting it a u_char* in the "my_callback" function. But I can't figure out how to get the length of the data. strstr didn't work. the header has a len member that you can access to get the size but I can't find anything similar for the *packet being passed. Any help is appreciated.

  • What'd be a good pattern on Doctrine to have multiple languages

    - by PERR0_HUNTER
    Hi! I have this challenge which consist in having a system that offers it's content in multiple languages, however a part of the data contained in the system is not translatable such as dates, ints and such. I mean if I have a content on the following YAML Corporativos: columns: nombre: type: string(254) notnull: true telefonos: type: string(500) email: type: string(254) webpage: type: string(254) CorporativosLang: columns: corporativo_id: type: integer(8) notnull: true lang: type: string(16) fixed: false ubicacion: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false contacto: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false tipo_de_hoteles: type: string(254) fixed: false unsigned: false primary: false notnull: true autoincrement: false paises: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false relations: Corporativo: class: Corporativos local: corporativo_id foreign: id type: one foreignAlias: Data This would allow me to have different corporative offices, however the place of the corp, the contact and other things can be translate into a different language (lang) Now this code here would create me a brand new corporative office with 2 translations $corporativo = new Corporativos(); $corporativo->nombre = 'Duck Corp'; $corporativo->telefonos = '66303713333'; $corporativo->email = '[email protected]'; $corporativo->webpage = 'http://quack.com'; $corporativo->Data[0]->lang = 'en'; $corporativo->Data[0]->ubicacion = 'zomg'; $corporativo->Data[1]->lang = 'es'; $corporativo->Data[1]->ubicacion = 'zomg amigou'; the thing now is I don't know how to retrieve this data in a more friendly way, because if I'd like to access my Corporative info in english I'd had to run DQL for the corp and then another DQL for the specific translation in english, What I'd love to do is have my translatable fields available in the root so I could simply access them $corporativo = new Corporativos(); $corporativo->nombre = 'Duck Corp'; $corporativo->telefonos = '66303713333'; $corporativo->email = '[email protected]'; $corporativo->webpage = 'http://quack.com'; $corporativo->lang = 'en'; $corporativo->ubicacion = 'zomg'; this way the translatable fields would be mapped to the second table automatically. I hope I can explain my self clear :( any suggestions ?

  • [java] Keystore change passwords

    Hi, I currently have a keystore, with a particular password that only I should know. I now need to give access to that keystore to someone else, so I would like to either: 1) Change the password, so I can share it with others and let them sign 2) Create a different password and allow them to sign with it. Is this possible? and - if yes - how?

    i've defined 'using' keyword as following: def using[A, B <: {def close(): Unit}] (closeable: B) (f: B => A): A = try { f(closeable) } finally { closeable.close() } i can use it like that: using(new PrintWriter("sample.txt")){ out => out.println("hellow world!") } now i'm curious how to define 'using' keyword to take any number of parameters, and be able to access them separately: using(new BufferedReader(new FileReader("in.txt")), new PrintWriter("out.txt")){ (in, out) => out.println(in.readLIne) }

  • Map /dev/bus/usb node to /sys node on Linux

    - by Cody Brocious
    I'm using libusb to find and access a USB device, but once I get the information I need from there, I need to map it to a /sys node. This could be to the actual USB bus it's on, the /sys/bus/usb-serial node (which is where I'm going to get eventually), or effectively anywhere else since I can walk the tree from there. I can get to a /dev/bus/usb node easily enough, but I'm a bit lost from there. What would be the best route to perform this mapping?
