  • Ember - ConnectOutlet - when does view change from preRender to inDom

    - by dagda1
    I am trying to get my head round the connectOutlet method and when a view that is returned from connectOutet is actually inserted into the DOM. The view that is created in connectOutlet leaves connectOutlet in the preRender state. connectOutlet: function(name, context) { // method body view = this.createOutletView(outletName, viewClass); if (controller) { set(view, 'controller', controller); } set(this, outletName, view); return view; } I've not tracked down where or when the view is inserted into the Dom and the view transitions to the inDom state. I suspect the runloop is at play and it transitions after the current runloop has finished. Can anyone shed any light on this?

  • What is the most efficient approach to fetch category tree, products, brands, counts by subcategory

    - by alex227
    Symfony 1.4 + Doctrine 1.2. What is the best way to minimize the number of queries to retrieve products, subcategories of current category, product counts by subcategory and brand for the result set of the query below? Categories are a nested set. Here is my query: $q = Doctrine_Query::create() ->select('c.*, p.product,p.price, b.brand') ->from('Category c') ->leftJoin('c.Product p') ->leftJoin('p.Brand b') ->where ('c.root_id = ?', $this->category->getRootId()) ->andWhere('c.lft >= ?', $this->category->getLft()) ->andWhere('c.rgt <= ?', $this->category->getRgt()) ->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $treeObject = Doctrine::getTable('Category')->getTree(); $treeObject->setBaseQuery($q); $this->treeObject = $treeObject; $treeObject->resetBaseQuery(); $this->products = $q->execute();

    - by Andrea
    Thanks for taking a look at this. I’ve been looking and looking for a solution to what seems like a simple thing to do but nothing yet. Here goes: When you click on "Specialty" in the main menu it goes here: Home /Specialty When you click one of the product images on the home page it goes here: Home /Specialty /Holiday Satin Stocking (Full product description page) I need all products with full product information to end up at Home /Specialty Page set-up would be: Click on Menu item or an image to show like this: |||Product1||| Product Description Add to cart |||Product2||| Product Description Add to cart |||Product3||| Product Description Add to cart I would like to override going "Home /Specialty /Holiday Satin Stocking" all together with listing all the information here: Home /Specialty "Specialty" is set up as an anchor and all products types are simple. Thanks so much!

  • Does '[ab]+' equal '(a|b)+' in python re module?

    - by user1477871
    I think pat1 = '[ab]' and pat2 = 'a|b' have the same function in Python(python2.7, windows) 're' module as a regular expression pattern. But I am confused with '[ab]+' and '(a|b)+', do they have the same function, if not plz explain details. ''' Created on 2012-9-4 @author: melo ''' import re pat1 = '(a|b)+' pat2 = '[ab]+' text = '22ababbbaa33aaa44b55bb66abaa77babab88' m1 = re.search(pat1, text) m2 = re.search(pat2, text) print 'search with pat1:', m1.group() print 'search with pat2:', m2.group() m11 = re.split(pat1, text) m22 = re.split(pat2, text) print 'split with pat1:', m11 print 'split with pat2:', m22 m111 = re.findall(pat1, text) m222 = re.findall(pat2, text) print 'findall with pat1:', m111 print 'findall with pat2:', m222 output as below: search with pat1: ababbbaa search with pat2: ababbbaa split with pat1: ['22', 'a', '33', 'a', '44', 'b', '55', 'b', '66', 'a', '77', 'b', '88'] split with pat2: ['22', '33', '44', '55', '66', '77', '88'] findall with pat1: ['a', 'a', 'b', 'b', 'a', 'b'] findall with pat2: ['ababbbaa', 'aaa', 'b', 'bb', 'abaa', 'babab'] why are 'pat1' and 'pat2' different and what's their difference? what kind of strings can 'pat1' actually match?

  • CSS: Fixed background images taller than the browser viewport

    - by jj_aa
    I've got a large photo (940x1210) as the background image for a #page div which wraps around all the content on a site. Since the photo is a headshot, it looks pretty silly tiled, so I've set it not to repeat, and positioned it at 0,0. When the content enclosed by #page is taller than 1210px and the background image is set to scroll, the photo scrolls out of view, but if it's fixed, only the part of the image displayed initially in the browser viewport shows up- either the top half (fixed top left) or bottom half (fixed bottom left). Here's the question: how can I fix the background image to the bottom of #page (or the body) while scrolling through the full height of the image until I get to the bottom?

  • Updating multiple rows with an array

    - by Copephobia
    I have a table that holds user information. One of the columns holds the position of the user in the game they are in. When a game is being created, I need to update the positions of the users of each team. Here is an example: Game id : 7 Team 1 users : 1,2 Team 2 users : 3,4 team1_position : array(1,2) team2_position : array(13,14) What I want to do is update the user table using the array of positions in the SET area. My goal is to be able to update the users without the need for their id (I have different size game boards, so I have multiple position arrays for each board size) How can I do something like this: UPDATE user SET position='(team1_position)' WHERE game = '7' AND team = '1' I feel like it would be a waste of resources to select all the id's of each team and update them separately.

  • Lambda "if" statement?

    - by AndyC
    I have 2 objects, both of which I want to convert to dictionarys. I use toDictionary<(). The lambda expression for one object to get the key is (i = i.name). For the other, it's (i = i.inner.name). In the second one, i.name doesn't exist. i.inner.name ALWAYS exists if i.name doesn't. Is there a lambda expression I can use to combine these two? Basically to read as: "if i.name exists then set id to i.name, else set id to i.inner.name". Many thanks.

  • What is the best instance type to use for hosting a website on ec2?

    - by Josh
    Amazon offers two instance types on EC2: 1) On-Demand and 2) Reserved. After reading the docs on these, I don't really understand the difference from an end-user perspective. More specifically, I'd like to know the answer to this question: is one or the other better for web applications? Based on their names and descriptions, it seems as though on-demand instances may get wiped away from the server altogether if they're not in use which means that they need to be restarted when a request finally does come in. That seems like a pretty bad thing for a website. Am I just misinterpreting the docs? Thanks!

  • why can't you use the debug/release version of a lib interchangeably

    - by user205834
    In C++, most of the libs come in Debug/Release versions. Question 1. What are the big difference between Debug and Release versions (e.g. what advantages do you have using one versus the other). Question 2. A lib is just has an implementation of the functions, how does a function implementation change if you are using debug/release versions? Question 3. Can you ever build your app in debug mode and use a release version of a lib? Thanks.

  • timing response speed of serial device

    - by dario frongi
    I comunicate with a serial device via bluetooth. i send it pid and it responds to me with a data response. i comunicate with him with serial comunicatione one request-response. i want to measure how many response i receive in one second. i think that i have to know the moment when i do the request and the moment whene i receive the response and do the difference. The result(called delta) is the time-to response of device. in the end i have to do 1000ms/delta. how can calculate it ?

  • Problems with the Enterframe Event

    - by user434565
    Hey guys, I have been developing a game using Flex, and used the Timer class to keep the main loop going. However, when I tried using the enterFrame event to do the main loop, there were a few problems. First of all, physics simulation seemed way too fast. Is the enterFrame event called more than once per frame? I set the application's global frame rate to 24, so shouldn't the application set off the event every 1/24 of a second? And the second problem is that when the game runs like this, some MXML components that are added are not shown. I have absolutely no idea why this happens. Help me please?!? Thanks.

  • What do you wish you could've learned sooner?

    - by Industrial
    What things, methods, workflows, etc. can you not live without today and wish you had learned of a long time ago? For example, learning some basic Ubuntu and using my debugger properly in the IDE have made a huge difference to me and are together probably the two things that I most wish I had done a long time ago. Using a debugger just seems like common sense now to many of us, but to those that are in a early stage of their career it might not. (I'm a good example of that.)

  • capture the last WM_SIZE

    - by Michael
    When I resize my window I want to tell another part of my program that my window has changed size. I read on MSDN that: WM SIZE Message The WM SIZE message is sent to a window after its size has changed. However, I receive the WM_SIZE even when dragging. I noticed that there is also a WM_SIZING message that is sent when my window is resizing. At the moment I do not see the difference between WM_SIZE and WM_SIZING. Is there some way I can capture the very last WM_SIZE message, as to not "spam" my program with resize messages?

  • Why delegate types are derived from MulticastDelegate class why not it directly derive from Delegate class?

    - by Vijay
    I have a very basic question regarding delegate types. I compared the memebers of Delegate and MulticastDelegate classes in object browser and I couldn't find any new additional member present in MulticastDelegate. I also noticed that the Delegate class has GetInvocationList virtual method. So I assume that the Delegate class should have the capability to hold references to multiple methods. If my assumption is correct I wonder why not custom delegate types directly derive from the Delegate class instead of MulticastDelegate class. Not sure what I am missing here. Please help me understand the difference.

  • Is new int[10]() valid c++?

    - by Naveen
    While trying to answer this question I found that the code int* p = new int[10](); compiles fine with VC9 compiler and initializes the integers to 0. So my questions are: First of all is this valid C++ or is it a microsoft extension? Is it guaranteed to initialize all the elements of the array? Also, is there any difference if I do new int; or new int();? Does the latter guarantee to initialize the variable?

  • iPhone OpenGL scrolling background jumps when texture is drawn for first time

    - by Magnum39
    I have been fighting a problem for a while now and would appreciate any help anybody could give. I have a sprite that moves within a landscape. The sprite remains in the center of the screen and the background moves to simulate that the sprite is moving within the landscape. I have split the landscape into sections so that I only draw the sections of the landscape that I need (are on screen). The Problem: As a new texture section of the screen appears on the screen (is drawn for the first time) the movement jumps. Almost like a frame is missed. I have done some timing experiments and I do not thinks a frame is missed. My processing is well below the 30fps that I have the animation set to. It only happens the first time the texture section is drawn. Is there something extra that is done the first time a texture is drawn? Here is the code: - (void) render{ // Sets up an array of values to use as the sprite vertices. const GLfloat sVerts[] = { -1.6f, -1.6f, 1.6f, -1.6f, -1.6f, 1.6f, 1.6f, 1.6f, }; static const GLfloat sTexCoords[] = { 0.0, 1.0, 1.0, 1.0, 0.0, 0.0, 1.0, 0.0 }; glDisableClientState(GL_COLOR_ARRAY); glEnableClientState(GL_VERTEX_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); // Setup opengl to draw the object in correct orientation, size, position, etc glLoadIdentity(); // Enable use of the texture glEnable(GL_TEXTURE_2D); glVertexPointer(2, GL_FLOAT, 0, sVerts); glTexCoordPointer(2, GL_FLOAT, 0, sTexCoords); // draw the texture // set the position of the first tile float xOffset = -4.8; float yOffset = 4.8; int i; int y; int currentTexture = textureA; for(i=0; i<2; i++) { for(y=0; y<2; y++) { // test for the texture tile on the screen if not on screen then do not draw float localX = xOffset+(3.21*y); float localY = yOffset-(3.21*i); float xDiff = monkeyX - localX; float yDiff = monkeyY - localY; if(((xDiff < 3.2) && (xDiff > -3.2)) && ((yDiff <2.7) && (yDiff > -2.7))) { // bind the texture and set the vertex data pointers glBindTexture(GL_TEXTURE_2D, spriteTexture[currentTexture]); // move to draw position for the texture glLoadIdentity(); glTranslatef((localX+self.positionX), (localY+self.positionY), 0.0); //draw the texture glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); } currentTexture++; } } }

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • MySQLI Prepared Statement Not Binding Properly

    - by Sev
    Any reason why the following code won't work? $dbconnection = db::getInstance(); //this is a singleton db class $stmt = $dbconnection->prepare("SELECT `id` from `table` where `username`=?"); $stmt->bind_param("s", $username); $stmt->execute(); $stmt->bind_result($uid); $stmt->fetch(); echo $uid; The same connection method is used elsewhere, and it works there. The only difference on that other page where it works, is that there are multiple rows fetched, not just one.

  • Eliminating inherited overlong MACRO

    - by ExpatEgghead
    I have inherited a very long set of macros from some C algorithm code.They basically call free on a number of structures as the function exits either abnormally or normally. I would like to replace these with something more debuggable and readable. A snippet is shown below #define FREE_ALL_VECS {FREE_VEC_COND(kernel);FREE_VEC_COND(cirradCS); FREE_VEC_COND(pixAccum)..... #define FREE_ALL_2D_MATS {FREE_2D_MAT_COND(circenCS); FREE_2D_MAT_COND(cirradCS_2); } #define FREE_ALL_IMAGES {immFreeImg(&imgC); immFreeImg(&smal..... #define COND_FREE_ALLOC_VARS {FREE_ALL_VECS FREE_ALL_2D_MATS FREE_ALL_IMAGES} What approach would be best? Should I just leave well alone if it works? This macro set is called twelve times in one function. I'm on Linux with gcc.

  • Loop through different sets of unique permutations

    - by user558610
    Hi I'm having a hard time getting started to layout code for this problem. I have a fixed amount of random numbers, in this case 8 numbers. R[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; That are going to be placed in 3 sets of numbers, with the only constraint that each set contain minimum one value, and each value can only be used once. For example: R1[] = { 1, 4 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } I need to loop through all possible combinations of a set R1, R2, R3. Order is not important, so if the above example happened, I don't need R1[] = { 4, 1 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } NOR R1[] = { 2, 8, 5, 6 } R2[] = { 7, 4 } R3[] = { 1, 4 } What is a good method?

  • What Math topics & resources to consider as beginner to indulge the book - Introduction to Algorithm

    - by sector7
    I'm a programmer who's beginning to appreciate the knowledge & usability of Algorithms in my work as I move forward with my skill-set. I don't want to take the short path by learning how to apply algorithms "as-is" but would rather like to know the foundation and fundamentals behind them. For that I need Math, at which I'm pretty "basic". I'm considering getting tuition's for that. What I would like is to have a concise syllabus/set of topics/book which I could hand over to my math tutor to get started. HIGHLY DESIRED: one book. the silver bullet. (fingers crossed!) PS: I've got some leads but want to hear you guys/gurus out: Discrete Math, Combinatorics, Graph theory, Calculus, Linear Algebra, and Number Theory. Looking forward to your answers. Thanks!

  • C++ Static Array Initialization - Memory Issue

    - by donalmg
    Hi, I have a header file which contains a member variable declaration of a static char array: class ABC { public: static char newArray[4]; // other variables / functions private: void setArray(int i, char * ptr); } In the CPP file, I have the array initialized to NULL: char ABC::newArray[4] = {0}; In the ABC constructor, I need to overwrite this value with a value constructed at runtime, such as the encoding of an integer: ABC::ABC() { int i; //some int value defined at runtime memset(newArray, 0, 4); // not sure if this is necessary setArray(i,newArray); } ... void setArray(int i, char * value) { // encoding i to set value[0] ... value [3] } When I return from this function, and print the modified newArray value, it prints out many more characters than the 4 specified in the array declaration. Any ideas why this is the case. I just want to set the char array to 4 characters and nothing further. Thanks...
