  • JavaScript data formatting/pretty printer

    - by Dan
    I'm trying to find a way to 'pretty print' a JavaScript data structure in a human-readable form for debugging. I have a rather big and complicated data structure being stored in JS and I need to write some code to manipulate it. In order to work out what I'm doing and where I'm going wrong, what I really need is to be able to see the data structure in its entirety, and update it whenever I make changes through the UI. All of this stuff I can handle myself, apart from finding a nice way to dump a JavaScript data structure to a human-readable string. JSON would do, but it really needs to be nicely formatted and indented. I'd usually use Firebug's excellent DOM dumping stuff for this, but I really need to be able to see the entire structure at once, which doesn't seem to be possible in Firebug. Any suggestions welcome, thanks in advance.

  • how to send JSON data with server error response code 500

    - by kapil.israni
    I wanted to know if theres a way to send a JSON data along with HTTP response code 500. Basically I want my rest client to know that there is some error on the backend and along with it send a JSON error data structure like this. {"error" : [ {"code": "1001", "desc": "Some error description"}, {"code": "1002", "desc": "Some other error description"} ] } This is using the following java stack = Java 6/JAX-RS/Jersey/Tomcat If not, then is there a way to send a custom response code along with JSON data. Basically looking from JAX-RS API it looks that you can only send JSON data along with 200 OK?? Any thoughts?? I am guessing RESTEasy would be the same, right??

  • Sending and Receiving data through SOAP web service in .Net

    - by Nikhil Thaker
    I am working on a client - server application and in which I used to send and receive data through SOAP web service. Now after sometimes I have heard from someone that I might lost some data while this process on soap service created in ASP.net. So now I have decided to send and receive data through batches like first I will send List of 50 objects and then next 50 and so on... Now I am new to web services and all. So my question is "Is it true that we can lost some data sometimes while transferring it through SOAP web service?"

  • Help needed with MySQL query to join data spanning multiple tables with data used as column names

    - by gurun8
    I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

  • Data Modeling of Entity with Attributes

    - by StackOverflowNewbie
    I'm storing some very basic information "data sources" coming into my application. These data sources can be in the form of a document (e.g. PDF, etc.), audio (e.g. MP3, etc.) or video (e.g. AVI, etc.). Say, for example, I am only interested in the filename of the data source. Thus, I have the following table: DataSource Id (PK) Filename For each data source, I also need to store some of its attributes. Example for a PDF would be "numbe of pages." Example for audio would be "bit rate." Example for video would be "duration." Each DataSource will have different requirements for the attributes that need to be stored. So, I have modeled "data source attribute" this way: DataSourceAttribute Id (PK) DataSourceId (FK) Name Value Thus, I would have records like these: DataSource->Id = 1 DataSource->Filename = 'mydoc.pdf' DataSource->Id = 2 DataSource->Filename = 'mysong.mp3' DataSource->Id = 3 DataSource->Filename = 'myvideo.avi' DataSourceAttribute->Id = 1 DataSourceAttribute->DataSourceId = 1 DataSourceAttribute->Name = 'TotalPages' DataSourceAttribute->Value = '10' DataSourceAttribute->Id = 2 DataSourceAttribute->DataSourceId = 2 DataSourceAttribute->Name = 'BitRate' DataSourceAttribute->Value '16' DataSourceAttribute->Id = 3 DataSourceAttribute->DataSourceId = 3 DataSourceAttribute->Name = 'Duration' DataSourceAttribute->Value = '1:32' My problem is that this doesn't seem to scale. For example, say I need to query for all the PDF documents along with thier total number of pages: Filename, TotalPages 'mydoc.pdf', '10' 'myotherdoc.pdf', '23' ... The JOINs needed to produce the above result is just too costly. How should I address this problem?

  • Database solutions for storing/searching EXIF data

    - by webdestroya
    I have thousands of photos on my site (each with a numeric PhotoID) and I have EXIF data (photos can have different EXIF tags as well). I want to be able to store the data effectively and search it. Some photos have more EXIF data than others, some have the same, so on.. Basically, I want to be able to query say 'Select all photos that have a GPS location' or 'All photos with a specific camera' I can't use MySQL (tried it, it doesn't work). I thought about Cassandra, but I don't think it lets me query on fields. I looked at SimpleDB, but I would rather: not pay for the system, and I want to be able to run more advanced queries on the data. Also, I use PHP and Linux, so it would be awesome if it could interface nicely to PHP. Any ideas?

  • Replacing ORM schema without dropping the entire data

    - by Udi
    Hey, I'm using OpenJPA as a JPA provider. Is there a way in which I can recreate the database tables (When an entity changes) without dropping the entire data? When an entity changes, I drop and create every table in the store, and obviously lose the data within. Is there a tool or product to keep the data somehow? Thanks, Udi

  • Unable to access LinkedIn conections using python rauth library

    - by srinath sastry
    I was trying out this example at https://github.com/litl/rauth/blob/master/examples/linkedin-web.py I get a 403, Access to connections denied error and it returns KeyError: '_total'. r_network option is present. Has anyone faced this issue? Also if you look at http://docs.python-requests.org/en/latest/user/quickstart/#oauth-authentication, the 'requests' library is initializing resource_owner_key, resource_owner_secret apart from the application keys. Not sure how these are getting passed from the 'rauth' library, Was wondering if that was causing this 403 error.

  • Network access when the Android phone is asleep

    - by Immortal
    I'm using a combination of alarm (set with AlarmManager) and background service to periodically synchronize data in my application. The only problem I have is that when sleep policy terminates Wi-Fi connection the synchronization no longer works. Is there a way to "wake up" the Wi-Fi connection that has been put to sleep? GMail somehow manages to do that because it notifies me about new e-mail even if the phone entered sleep mode.

  • How to save bytes to an image and access it from Bottle

    - by Graham Smith
    I'm working on an API wrapper for Snapchat using Python and Bottle, but in order to return the file (retrieved by the Python script) I have to save the bytes (returned by Snapchat) to a .jpg file. I'm not quite sure how I will do this and still be able to access the file so that it can be returned. Here's what I have so far, but it returns a 404. @route('/image') def image(): username = request.query.username token = request.query.auth_token img_id = request.query.id return get_blob(username, token, img_id) def get_blob(usr, token, img_id): # Form URL and download encrypted "blob" blob_url = "https://feelinsonice.appspot.com/ph/blob?id={}".format(img_id) blob_url += "&username=" + usr + "&timestamp=" + str(timestamp()) + "&req_token=" + req_token(token) enc_blob = requests.get(blob_url).content # Save decrypted image FileUpload.save('/images/' + img_id + '.jpg') img = open('images/' + img_id + '.jpg', 'wb') img.write(decrypt(enc_blob)) img.close() return static_file(img_id + '.jpg', root='/images/')

  • String Manipulation: Splitting Delimitted Data

    - by Milli Szabo
    I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?

  • Java Socket fails to transmit data over the network

    - by Mark Griffin
    I'm experiencing a bizarre problem with sockets between a Java Knopflerfish client bundle and a PHP (CLI, not web) server. The client/server pair work fine when both are located on the localhost, and all data is transmitted successfully. However, when the Java client exists on a different machine, connections to the server are successful, but no data is received by the PHP script. Packet analysis confirms that the data sent by the Java client is received on by the server - PHP just seems to have problems getting its hands on it. As a further note, I've done some tests with telnet as the client. The PHP server script receives all data fine from any host. This leads me to believe that the problem has something to do with the way java is setting up the socket or that there is some networking issue that I'm not familiar with. Any thoughts would be appreciated. Can post code samples if desired.

    Apologies if this is the wrong place to ask this. I have an Android app on the market that has a reported problem on Droid and Nexus One (both with Android 2.1). I don't have access to the handset and cannot find anyone with one where I live. The problem I'm experiencing is partially explained at: http://stackoverflow.com/questions/2700983/problem-saving-file-on-motorola-droid-android-2-1. If you are an Android developer with either of those handsets, I'm happy to pay a reasonable fee if you'll debug the app for me. I'll send you the source. Please email me at [email protected]

  • Can't add object to Array in jQuery's getJSON data function (scope issue)

    - by seo20
    I have a person object and wants to store it into a global ArrayCollection I have made. Works great in normal scope: var s = new ArrayCollection(); s.add(new person("Knud", "Mikkelsen", 35)); The problem is when I want to add people inside my jQuery function "mainFunction". I can't seem to get it right. I know it's something to do with scope and I have to wrap something in functions like in my ArrayCollection. Please help me - thanks a lot. function ArrayCollection() { var myArray = new Array; return { empty: function () { myArray.splice(0, myArray.length); }, add: function (myElement) { myArray.push(myElement); }, getAll: function () { return myArray; } } } function person(firstName, lastName, age) { this.firstName = firstName; this.lastName = lastName; this.age = parseInt(parseFloat(age)); } function mainFunction() { //.... var s = new ArrayCollection(); s.add(new person("Knud", "Mikkelsen", 35)); $.getJSON(url, function (data) { for (var x = 0; x < data.length; x++) { var myPerson = new person(data[x].FirstName.toString(), data[x].LastName.toString(), data[x].Age.toString()); s.add(myPerson); } }); alert(drawArray(s.getAll())); } function drawArray(myArray) { var v = ""; for (var i = 0; i < myArray.length; i++) { v += myArray[i].firstName + " " + myArray[i].lastName + " (" + myArray[i].age + ")\n"; } return v; }

  • How to access stdClass variables stdClass Object([max(id)])=>64)

    - by Theopile
    I need the very last valid entry in a database table which would be the row with the greatest primary key. So using mysqli, my query is "SELECT MAX(id) FROM table LIMIT 1". This query returns the correct number(using print_r()) but I cannot figure out how to access it. Here is the main code. Note that the $this-link refers to class with a mysqli connection. $q="select max(id) from stones limit 1"; $qed=$this->link->query($q) or die(mysqli_error()); if($qed){ $row=$qed->fetch_object(); print_r($row); echo $lastid=$row;//here is the problem } The valid line print_r($row) echos out "stdClass Object ( [max(id)] = 68 )"
