• Selecting a portion of a JSON array and applying variables in javascript or jquery

  - by user1644609

  I am retrieving a JSON file that returns its results like what you see below. The JSON has 365 days worth of data. I would like to create "views" of this JSON using javascript, one which pulls the last 10 days, then 1 month, 6 months, etc. After the getJSON function I am doing this to get a string as JSON, then turn it into an object and will then graph it. So I would like each "view" to be an object for the specified timeframe (using the one JSON). The obj_10days, obj_1month, etc variables would then be plotted. var $ graph = data ; var obj = $ . parseJSON ( $ graph ) ; JSON: [ { "Low": 8.63, "Volume": 14211900, "Date": "2012-10-26", "High": 8.79, "Close": 8.65, "Adj Close": 8.65, "Open": 8.7 }, { "Low": 8.65, "Volume": 12167500, "Date": "2012-10-25", "High": 8.81, "Close": 8.73, "Adj Close": 8.73, "Open": 8.76 }, { "Low": 8.68, "Volume": 20239700, "Date": "2012-10-24", "High": 8.92, "Close": 8.7, "Adj Close": 8.7, "Open": 8.85 }, Any help is appreciated, thank you!

• Find node level in a tree

  - by Álvaro G. Vicario

  I have a tree (nested categories) stored as follows: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci I need to feed my client-side language (PHP) with node information (child+parent) so it can build the tree in memory. I can tweak my PHP code but I think the operation would be way simpler if I could just retrieve the rows in such an order that all parents come before their children. I could do that if I knew the level for each node: SELECT category_id, category_name, parent_id FROM category ORDER BY level -- No `level` column so far :( Can you think of a way (view, stored routine or whatever...) to calculate the node level? I guess it's okay if it's not real-time and I need to recalculate it on node modification.

• Debugging (displaying) SQL command sent to the db by SQLAlchemy

  - by morpheous

  I have an ORM class called Person, which wraps around a person table: After setting up the connection to the db etc, I run the ff statement. people = session.query(Person).all() The person table does not contain any data (as yet), so when I print the variable people, I get an empty list. I renamed the table referred to in my ORM class People, to people_foo (which does not exist). I then run the script again. I was surprised that no exception was thrown when attempting to access a table that does not exist. I therefore have the following 2 questions: How may I setup SQLAlchemy so that it propagates db errors back to the script? How may I view (i.e. print) the SQL that is being sent to the db engine If it helps, I am using PostgreSQL as the db

• Why I cant be able to change the UITableViewCell detailTextLabel's frame (just the label's position)?

  - by Simon

  Hi.. I am having a table view with default UITableViewCell of style UITableViewCellStyleValue2. I just want to move detailTextLabel few pixels to the right. I know it makes no sense to adjust its width and height :). I am trying to set detailTextLabel's frame with my x and y value. But its not affecting the its frame. I prefer to use default UITableViewCell, in this case, over a customized cell because the default UITableViewCell automatically manages the text alignment and centering of the labels.. How to change UITableViewCell detailTextLabel's frame? Am I allowed to change its frame? Thanks everyone..

• Cascading MVC controllers with CatchAll Routes

  - by Richard

  Hi, I have an MVC app which has its routes defined with the final route being a catch all route to a "PageController" for a database driven collection of pages. What I want to achieve is to be able to plugin to the app a second controller to the catch all route which the first controller passes on to if it does not find the url recieved in the database. Effectively I want to queue up controllers with catch all actions: public ActionResult PageCatchall(string url) { var page = repository.Get<Page>(string url); if (page != null) { // Handle the request return View(page) } // Otherwise pass to a new controller ???? } Anyone have any good ideas as to how to solve this? I have tried RedirectToAction but that requires that the next controller has a different route to the action. I have tried ActionInvoker but this failed to work the way I did it.

• MediaWiki: workaround for watchlist restricted to 7 days?

  - by Mark Robinson

  I'm running MediaWiki 1.13.2. When I go to my watchlist, I'm limited to only viewing the last 7 days (though MediaWiki should permit me to view the last 30 days). I've tried: Clicking the all button Changing the URL Changing the settings under MY PREFERENCES-WATCHLIST. When I save (e.g. 30 days) it resets back to 7 days! Googling for an answer... Anyone heard of this bug before? Is there a workaround? I can't see a setting anywhere for this to be a maximum.

• iPad: How can I implement a scrolling timeline using a static image?

  - by BeachRunnerJoe

  I'm diving into iOS development and I'm building a simple timeline app using a static timeline image that I already have. The timeline image won't fit on the screen. The width of the image is about five times the width of the iPad screen, so I have to allow the user to scroll the image horizontally. Here's a mockup... For each item on the timeline, the user can tap it to receive a description at the bottom of the screen. My questions are... I was planning to use a UIScrollView with a PageControl at the bottom. Can a UIScrollView hold a single view that holds the entire timeline image or do I have to break the the timeline image up into multiple views? Are there any performance issues I need to consider when implementing this with a UIScrolLView, using a static image? Are there other approaches to implementing this scrollable timeline that I should consider other than using a UIScrollView? Thanks so much in advance for your wisdom!

• Wordpress & Vanity User URLs

  - by st4ck0v3rfl0w

  Hi All, Was wondering if anyone had any smart approaches to creating dynamic vanity user urls upon user registration. My site basically uses emails as usernames. I have the regex to strip the text before the "@" symbol (e.g. "[email protected]" becomes "name") I would then like to take the "name" and create a vanity url (e.g. domain.com/name or name.domain.com) Any thoughts on how to accomplish this with Wordpress? I'm a pretty advanced Wordpress user and my first thoughts were to do the following Verify user registration Upon successful user registration create page name with username as the title (this would help me achieve the www.domain.com/username) Apply preset template to that page with the desired view Any and all thoughts are welcome.

• Django forms: prepopulate form with request.user and url parameter

  - by Malyo

  I'm building simple Course Management App. I want Users to sign up for Course. Here's sign up model: class CourseMembers(models.Model): student = models.ForeignKey(Student) course = models.ForeignKey(Course) def __unicode__(self): return unicode(self.student) Student model is extended User model - I'd like to fill the form with request.user. In Course model most important is course_id, which i'm passing into view throught URL parameter (for example http://127.0.0.1:8000/courses/course/1/). What i want to achieve, is to generate 'invisible' (so user can't change the inserted data) form with just input, but containing request.user and course_id parameter.

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

• How to track conversion rate (clicks to sales) from an internal advertising system?

  - by Ed Woodcock

  I am currently writing an interal advertising system for a company client's website, where the adverts will only be seen by internal users, and all transactions take place internally to the site (i.e. the adverts are for member-only content available on the site). Does anyone have any recommendations as to the best way to track the conversion rate of these adverts (i.e. views:clicks:sales)? EDIT I'm not looking for a 'Why don't you use google analystics'-type answer, I'm looking into possible architecture outlines, i.e. a 'why don't use store a guid in a cache temporarily and see if it ties to the advert' kind of answer. /EDIT In a previous job I did something based on an internal cache, which simply did view:click tracking, however the addition of the sales rate makes this task more complex, especially if we take into account the idea that someone may click through to an advert and not purchase immediately. Cheers, Ed (N.B. I'm leaving this purposely vague in order to (hopefully) get some answers that provide ideas I've yet to have thought of by coming at the problem from a different angle)

• How to raise an event when another event is raised?

  - by WulfgarPro

  Hi, I have an application that handles the OnQuit event of another running application. I would like to raise an additional (custom) event when the OnQuit event is handled. How could I implement such an event? My OnQuit handler is like so: private void StkQuit() { _stkApplicationUi.OnQuit -= StkQuit; Marshal.FinalReleaseComObject(_stkApplicationUi); Application.Exit(); } The reason I require the additional event is so that I can tell my View layer that the application has exited. If this is not the correct way, what would be better? WulfgarPro

• Why isn't a JS file hosted on Amazon S3 getting cached by the browser?

  - by Paras Chopra

  I have a JS file hosted on Amazon S3 (http://s3.amazonaws.com/wingify/vis_opt.js). I want the file to be cached on users' browsers so that they don't have to download it with every page view. However, in spite of setting Cache Control header I don't think it is getting cached. Browser still contacts Amazon Server with every pageview. Here is the example of page where this script is embedded: http://myjugaad.in/ If you have Firebug, you will be able to see that browser requests it with every pageview. What can I do so that the file gets permanently cached? Thanks for help.

• What exactly is GRASP's Controller about?

  - by devoured elysium

  What is the idea behind Grasp's Controller pattern? My current interpretation is that sometimes you want to achieve something that needs to use a couple of classes but none of those classes could or has access to the information needed to do it, so you create a new class that does the job, having references to all the needed classes(this is, could be the information expert). Is this a correct view of what Grasp's Controller is about? Generally when googling or SO'ing controller, I just get results about MVC's (and whatnot) which are topics that I don't understand about, so I'd like answers that don't assume I know ASP.NET's MVC or something :( Thanks
