  • Iterating through facebook comments JSON object failing

    - by user1594304
    I tried the option of students.item["http://www.myurl.com"].comments.data.length. However, the item["http://www.myurl.com"] call is not working. If I take out the URL from JSON object and write the iterator with students.comments.data, it works. Here is my code, any help highly appreciated. var students = { "http://www.myurl.com":{ "comments":{ "data" : [ { "id": "123456778", "from": { "name": "XYZ", "id": "1000005" }, "message": "Hey", "can_remove": false, "created_time": "2012-09-03T03:16:01+0000", "like_count": 0, "user_likes": false } ] } } } var i=0 var arrayObject = new Array(); alert("Parsing 2: "+students.item["http://www.myurl.com"].comments.data.length); for(i=0;i<students.item["http://www.myurl.com"].comments.data.length;i++) { alert("Parsing 1: "+i); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].id); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].message); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].created_time); }

    Hey guys quick question, I am kind of a noob at administering my server right now. I was just wondering if anyone could let me know what I was doing wrong in trying to enable mod_deflate.

  • sql - duplicates

    - by Sebastjan
    Hey guys I'm putting data from website (json) to sql base. In db i have these rows. ID | PostId | Name | Message Id is auto-increment primary key. PostId also has a unique values. Name and Message are nothing special. When I run my script / click on the button in form / ... , the program saves all the values into database (lets say there are 25). Next time I'm going to press the button there will be added 25 more records (all duplicates), and so on... Is there a way that the program can check through 'PostIds' if the value already exists before adding it to the db? Thanks

  • Magento get loaded collection

    - by Zertalx
    Hey guys I got an issue in magento when listing products. $_productCollection = array(); $key = 'product_collection_'.Mage::app()->getRequest()->getRequestUri(); $_productCollection = Mage::helper('cache')->getDataInCache($key); if (empty($_productCollection)) { $_productCollection=$this->getLoadedProductCollection(); Mage::helper('cache')->setDataInCache($key,$_productCollection,'front_end_collection'); } That's my code, i'm loading the collection and saved in cache, the problem is that I added new products from the admin panel but they are not showing up in the listing. I have refreshed cache, reindex all the data and checke that the products were in stock. Also check the visibility because i understand that the collection gets just the visible products, am i correct? I'm using magento enterprise 1.9 I'm new in magento and i'm having troubles understanding how the Collections works, i hope somebody can help me. Thanks

  • Reading in MIPS external file so another file can use it?

    - by SkyWookie
    Hey all, I'm working on this final thing for my MIPS project and it's deceptively easy. I need to get a procedure (called feed) and let its main driver program use it by reading it in. I know that I'm supposed to use the call code 14 and .globl sym (I think) in order to feed it into the file and have it read it. I just need a basic tutorial or something, as I CANNOT find it on the Internet or in my book (just lists the call code, real helpful). Here's what I know: I need to use read, but I also need a file descriptor (don't know where to get it). I need to put the buffer in $a1 and the length in $a2. Well, that's about it. If there's any decent tutorial you could whip up or if there is one online that I don't see let me know please :). I just need a push in the right direction, I'm sure it can't be too difficult, just can't find any info on it!

  • 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 eval code

    - by xpepermint
    Hey. I have to do a coll inside my model like this: import = Import.find(id) status = User.find(import.user_id).{XXX}.import(import.file.path) Notice a {XXX} which should be replaced by a dinamic variable of a submodel. Model User has_many groups, clients and products. In translation this would be status = User.find(import.user_id).groups.import(import.file.path) status = User.find(import.user_id).clients.import(import.file.path) status = User.find(import.user_id).products.import(import.file.path) I was thinking of import = Import.find(id) status = eval("User.find(#{import.user_id}).#{import.model}").import(import.file.path) but this gives me an error 'TypeError: can't convert nil into String'. Please tell me how would you fix that. Thx!

  • Obj-C: Creating an object with a String name

    - by FnGreg7
    Hey all. I know this sounds simple, but I can't find a way to do it. I have a method in Obj-C that takes in a NSString and then should create a new class with the String as its title. -(DataModel *)createDataModel:(NSString *)dataModel_name { DataModel *[initWithString:dataModel_name] = [[DataModel alloc] init]; } I know I have some problems in this. For starters, I don't know how to define a return on an object whose name could change. Second, I know this doesn't compile considering the initWithString method is wrong. I just don't know what to do or what method to use so that I can create this DataModel object with the specified name...

  • update dialog title for each click

    - by Scarface
    Hey guys I have a quick question, I have a dialog box that has multiple links with different attributes. Each time a link is clicked, the attribute src is printed inside of the dialog box so that each link has a unique output in the dialog. My problem is simply that only the first src title is in every box and I would like to change that as well with each click. I separated the line containing title to show the problem. If anyone has any ideas I would appreciate it. <a class="open" src="something" title="Click to play">link</a> <a class="open" src="something else" title="Click to play">link2</a> $('.open').click(function() { src=$(this).attr('src'); $('#show').html(''+src+''); $(\"#show\").dialog({hide: 'clip', width: 400,height: 150,position: 'center', show: 'clip',stack: true,title: ''+src+'', minHeight: 25, minWidth: 100, autoOpen: false,resizable:false}); $('#show').dialog('open'); })

    Hey everyone, I'm having trouble with this algorithm to extract the get variables from a url and print them each on a new line like: x=y z=hello etc. but instead it prints a seemingly random section of the url with no newlines to the file.

  • Need help with a sub query/group/order (get latest comment for each ordered topic)

    - by Scarface
    Hey guys I have a query that currently finds the latest comment for each of a user's topics and then orders topics by that comment's timestamp. What I want to do is expand on this query's use and print the latest comment for each topic. The problem with this query is that while it orders the topics correctly, it prints seemingly random comments for each topic. I am trying to implement a sub query but I am not quite sure how to approach it. I was thinking that I just had to somehow use this query to get the comments. If anyone has any ideas I would really appreciate it. Here is what I think I need to add SELECT * FROM comments where topic_id='$topic_id' ORDER BY timestamp DESC LIMIT 1 Here is the query I need to modify SELECT topic.topic_title, topic.content_type, topic.subject_id, topic.creator, topic.description, topic.topic_id,comments.message,comments.user FROM comments JOIN topic ON topic.topic_id = comments.topic_id WHERE topic.creator = '$user' AND comments.timestamp > $week GROUP BY topic_id ORDER BY MAX(comments.timestamp) DESC

  • C# Events between threads executed in their own thread (How to) ?

    - by Guillaume
    Hello, I'd like to have two Threads. Let's call them : Thread A Thread B Thread A fires an event and thread B listen to this event. When the Thread B Event Listener is executed, it's executed with the Thread A's thread ID, so i guess it is executed within the Thread A. What I'd like to do is be able to fire event to Thread B saying something like: "hey, a data is ready for you, you can deal with it now". This event must be executed in its own Thread because it uses things that only him can access (like UI controls). How can I do that ? Thank you for you help.
