  • [rails] user's account backup and restore

    - by Cédric
    Hi everyone, I am currently working on a project and i would like my users to be able to backup/restore theirs accounts. I am looking for a rails plugin/gem that would easily do that, ie : current_user.backup() = backup_file current_user.restore(backup_file) = database import/replace I don't know if my question is very clear, but i would like to backup every user's related object (posts, comments, etc) and to be able to restore them from a backup file. Thanks per advance, Cédric.

  • How do I create a random method name

    - by Russ Bradberry
    I plan on using JSONP to call an external webservice to get around the fact that I dont want to create a global function that could potentially conflict with the calling page. I thought that creating a random function name and passing it up would work. Something like this: <script src="www.foo.com/b?cb=d357534"> where cb is the callback function name, the server would return d357534({my json data}); what i want to know is how to create the random function name, im sure i could use eval but is this the best way to go about it? essentially, what i am trying to do is this: var d + Math.floor(Math.random()*1000001) = function(){...

  • sanitation script in php for login credentials...

    - by Matt
    What I am looking for currently is a simple, basic, login credentials sanitation script. I understand that I make a function to do so and I have one...but all it does right now is strip tags... am I doomed to use replace? or is there a way i can just remove all special characters and spaces and limit it to only letters and numbers...then as for the password limit it to only letters and numbers exclimation points, periods, and other special chars that cannot affect my SQL query. Please help :/ Thanks, Matt

  • Duplicating an array of strings.

    - by Jon
    arr = ["red","green","yellow"] arr2 = arr.clone arr2[0].replace("blue") puts arr.inspect puts arr2.inspect produces: ["blue", "green", "yellow"] ["blue", "green", "yellow"] Is there anyway to do a deep copy of an array of strings, other than using Marshal as i understand that is a hack. I could do: arr2 = [] arr.each do |e| arr2 << e.clone end but it doesn't seem very elegant, or efficient. Thanks

  • Gears or HTML5 Location API on Android 1.5

    - by Dmitry
    Hi there, I am trying to use gwt-mobile-webkit, particularly its location api. It works well with iPhone (both device and simulator) and Firefox and on G1 with 1.6 Android, however, it does not work on G2 with Android 1.5 on it. In result I am getting onFailure callback with Permission Denied error. So it seems, that there is some geolocation API (gears or HTML5) in the browser available, but it just does not want to ask user for granting permissions. Do you know if there is any workaround or just enable it somewhere in settings?

  • Dealing with wacky encodings in Python

    - by Tyson
    I have a Python script that pulls in data from many sources (databases, files, etc.). Supposedly, all the strings are unicode, but what I end up getting is any variation on the following theme (as returned by repr()): u'D\\xc3\\xa9cor' u'D\xc3\xa9cor' 'D\\xc3\\xa9cor' 'D\xc3\xa9cor' Is there a reliable way to take any four of the above strings and return the proper unicode string? u'D\xe9cor' # --> Décor The only way I can think of right now uses eval(), replace(), and a deep, burning shame that will never wash away.

  • Can't resolve CalledFromWrongThreadException with Handler

    - by michel
    I will try to keep it simple: In my main activity I make a handler: public class ARViewer extends ARDisplayActivity { public final MHandler mHandler = new MHandler(this); public void onCreate(Bundle savedInstanceState) { ... The class MHandler: public final class MHandler extends Handler{ //main activity private ARViewer arnv; public MHandler(ARViewer arnv){ this.arnv = arnv; } @Override public void handleMessage(Message msg) { ... case H_RR : arnv.setContentView(R.layout.routeplanner); break; ... super.handleMessage(msg); } } But if I call the handleMessage method from a callback function in a other Class, definitely from a other thread, I still get the exception message: CalledFromWrongThreadException (Only the original thread that created a view hierarchy can touch its views) : public void rFound(Route route) { Message msg = new Message(); msg.what = MHandler.H_RR; ARViewer.arnv.mHandler.handleMessage(msg); }

  • Sending BLOBs in a JSON service,... how?

    - by Marten Sytema
    Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

  • Return back to the parent activity from subactivity

    - by ZelluX
    My application supports twitter and needs to open browser for OAuth. When the user clicks the Share on Twitter button, the main activity will create another subactivity (TwitterActivity) to handle twitter authentication issues. Here is a flow graph showing how activities are invoked currently. Main is short for MainActivity and Twit for TwitterActivity. startActivity() OAuth intent OAuth callback finish() Main ---------------> Twit ------------> Browser --------------> Twit --------> Browser As you may notice, after the TwitterActivity calls finish() to stop, it will now return back to MainActivity, but Browser instead. How can I make it return back to MainActivity? Many thanks
