  • Question about the code of the backend of symfony

    - by user248959
    Hi, this is the index action and template generated at the backend for the model "coche". public function executeIndex(sfWebRequest $request) { // sorting if ($request->getParameter('sort') && $this->isValidSortColumn($request->getParameter('sort'))) { $this->setSort(array($request->getParameter('sort'), $request->getParameter('sort_type'))); } // pager if ($request->getParameter('page')) { $this->setPage($request->getParameter('page')); } $this->pager = $this->getPager(); $this->sort = $this->getSort(); } This is the index template: <?php use_helper('I18N', 'Date') ?> <?php include_partial('coche/assets') ?> <div id="sf_admin_container"> <h1><?php echo __('Coche List', array(), 'messages') ?></h1> <?php include_partial('coche/flashes') ?> <div id="sf_admin_header"> <?php include_partial('coche/list_header', array('pager' => $pager)) ?> </div> <div id="sf_admin_bar"> <?php include_partial('coche/filters', array('form' => $filters, 'configuration' => $configuration)) ?> </div> <div id="sf_admin_content"> <form action="<?php echo url_for('coche_coche_collection', array('action' => 'batch')) ?>" method="post"> <?php include_partial('coche/list', array('pager' => $pager, 'sort' => $sort, 'helper' => $helper)) ?> <ul class="sf_admin_actions"> <?php include_partial('coche/list_batch_actions', array('helper' => $helper)) ?> <?php include_partial('coche/list_actions', array('helper' => $helper)) ?> </ul> </form> </div> <div id="sf_admin_footer"> <?php include_partial('coche/list_footer', array('pager' => $pager)) ?> </div> </div> In the template there is this line: include_partial('coche/filters', array('form' => $filters, 'configuration' => $configuration)) ?> but i can not find the variables $this-filters and $this-configuration in the index action. How is that possible? Javi

  • question about InnoDB deadlock in MySQL?

    - by WilliamLou
    I found this kind of interesting problem in MySQL InnoDB engine, could anyone explain why the engine always claim it's a deadlock. First, I created a table with a single row, single column: CREATE TABLE `SeqNum` (`current_seq_num` bigint(30) NOT NULL default '0', PRIMARY KEY (`current_seq_num`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 | Now, I have two MySQL connector threads, In thread1: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; Query OK, 1 row affected (0.00 sec) Now, in thread2, I did the exactly same: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; before the default innodb_lock_wait_timeout, the thread2 just wait for thread1 to release its exclusive lock on the table, and it's normal. However, in thread1, if I input the following update query: mysql> update SeqNum set `current_seq_num` = 8; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction Now, thread2 get the select query finished because thread1 quits. In addition, in thread1, if I input the update query with a where clause, it can be executed very well: mysql> update SeqNum set `current_seq_num` = 8 where `current_seq_num` =5 Query OK, 1 row affected (0.00 sec) Could anyone explain this?

  • Android NDK Question

    - by Kyle
    The NDK does not contain very many shared libraries for you to access. As a result, I must build many sources myself and link them into my shared library via static/shared libraries. I want to compile libpng as a Static Library. Trouble is, I have absolutely no idea how, nor does google instruct you how to do so in their NDK. I'm no expert on the NDK even after reading everything I can find, so I would really appreciate someone who actually knows how this is done. I do have the Android.mk file for libpng, as google's Android OS source contains it. Infact, I got the entire directory on the android OS source for libpng and it's dependent libraries. It was somewhat of a shortcut instead of making one myself. I don't know how to make a particular directory which contains this file, though. Thanks for reading!

  • Math algorithm question

    - by Senica Gonzalez
    I'm not sure if this can be done without some determining factor....but wanted to see if someone knew of a way to do this. I want to create a shifting scale for numbers. Let's say I have the number 26000. I want the outcome of this algorithm to be 6500; or 25% of the original number. But if I have the number 5000, I want the outcome to be 2500; or 50% of the original number. The percentages don't have to be exact, this is just an example. I just want to have like a sine wave sort of thing. As the input number gets higher, the output number is a lower percentage of the input. Does that make sense?

  • css div positioning question

    - by SoulieBaby
    Hi all, I have three divs with the following css: div#container { width: 780px; } div#photos { width: 780px; height: 300px; } div#content { position: relative; top: -106px; width: 780px; } <div id="container"> <div id="photos">photos are here</div> <div id="content">content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer content goes here, but sits slightly on top of the photos layer</div> </div> My problem is that because I've set the content layer to be top:-106px there's a big gap underneith, when I wanted the "container" div to end immediately after the "content" div. I tried setting margin-bottom: -106px on the "container" div but that didn't change the height of the "container" div.. The "content" div will have varied height as it's obviously for text, etc. Is there any way of making this work? Thanks in advance :)

  • MSDN Subscription Question for the lone developer

    - by BrianLy
    I'm looking to get an MSDN Subscription and I see a number of sites offering 2 year subscriptions versions. Are these sites offering a regular version that I can buy or are they for Software Assurance customers only? I don't want to buy one and find out I cannot activate it because I'm not associated with a company that has SA.

  • OpenGLES mix and match blending options complicated question

    - by DevDevDev
    So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

  • Better ways to implement a modulo operation (algorithm question)

    - by ryxxui
    I've been trying to implement a modular exponentiator recently. I'm writing the code in VHDL, but I'm looking for advice of a more algorithmic nature. The main component of the modular exponentiator is a modular multiplier which I also have to implement myself. I haven't had any problems with the multiplication algorithm- it's just adding and shifting and I've done a good job of figuring out what all of my variables mean so that I can multiply in a pretty reasonable amount of time. The problem that I'm having is with implementing the modulus operation in the multiplier. I know that performing repeated subtractions will work, but it will also be slow. I found out that I could shift the modulus to effectively subtract large multiples of the modulus but I think there might still be better ways to do this. The algorithm that I'm using works something like this (weird pseudocode follows): result,modulus : integer (n bits) (previously defined) shiftcount : integer (initialized to zero) while( (modulus<result) and (modulus(n-1) != 1) ){ modulus = modulus << 1 shiftcount++ } for(i=shiftcount;i>=0;i++){ if(modulus<result){result = result-modulus} if(i!=0){modulus = modulus << 1} } So...is this a good algorithm, or at least a good place to start? Wikipedia doesn't really discuss algorithms for implementing the modulo operation, and whenever I try to search elsewhere I find really interesting but incredibly complicated (and often unrelated) research papers and publications. If there's an obvious way to implement this that I'm not seeing, I'd really appreciate some feedback.

  • Question on SyndicationItem - ASP.NET

    - by bobsmith123
    I am trying to understand how to use SyndicationItem to display feed which is RSS 2.0 or Atom compliant. What property of SyndicationItem gives me the entire description of the post. It appears that there is a Summary property but per MSDN, it gives only the Summary. Also I have noticed that in my RSS feed reader, some RSS feeds show only a few lines of description and I have to click and go to the website for the full post. But in some feeds, I can see the full post within the Feed Reader. Can someone explain how all this comes together? PS: My web page lets user enter a RSS feed address and I need to validate if the feed exists. If it does, I need to grab the last x items and show the feed's title and full description

  • Grails/Compass question - How can I change the compqass Connection to point to a different directory

    - by ombud
    Hi, I use the Searchable plugin with Grails I have the need to change the directory to which Compass points to, depending upon a UI choice by the user. Normally, this value is set in the compassConnection variable of the searchable map in grails-app/conf/Searchable.groovy, like so, and gets called at app startup time: searchable { compassConnection = new File( "/path/to/index/file/directory" ).absolutePath ... } To do what I need to do, I think that I need to get a handle into the compass config variable and then call config.setConnection("/new/path/to/index/dir") I don't know how I can get a reference to the config compass variable Am I right in assuming that I need to call setConnection(String) only, or is(are) there any other step(s) I need to take? Really appreciate any help that I can get, Shailen

  • .animate question/help

    - by Josh
    So, I've built this navigation bar so far and I'm curious if it's even possible to achieve what I'm thinking. Currently, when you hover over each of the links they drop down (padding is increased). Now, what I'm curious in doing is if you hover over say "test1", test2-4 also drop with it but in the padding that has been created from the drop down, "test1" information shows up. Allowing the user to click or read whatever information is in there. Also, if the user would like to, they can move their mouse to test2 and everything would animate (opacity, this I can do I think) to whatever is in the test2 field, test3 doing the same and so on. I haven't had much success with this, I've created a completely separate panel before, but that didn't exactly work or I wasn't doing it correctly. Here is what I've been working on, ANY help would be appreciated!

  • JavaScript replace with callback - performance question

    - by Tomalak
    In JavaScript, you can define a callback handler in regex string replace operations: str.replace(/str[123]|etc/, replaceCallback); Imagine you have a lookup object of strings and replacements. var lookup = {"str1": "repl1", "str2": "repl2", "str3": "repl3", "etc": "etc" }; and this callback function: var replaceCallback = function(match) { if (lookup[match]) return lookup[match]; else return match; } How would you assess the performance of the above callback? Are there solid ways to improve it? Would if (match in lookup) //.... or even return lookup[match] | match; lead to opportunities for the JS compiler to optimize, or is it all the same thing?

  • XQuery method question, trying to sum values read from xml

    - by Buck
    I'm pretty new to XQuery and I'm trying to write an example function that I can't get to work. I want to read an xml file, parse out the "time" values, sum them as they're read and return the sum. This is trivial and I'm looking to build more functionality into it but I'd like to get this working first. Also, I know there's a "sum" directive in XQuery that would do just this but I want to add more to it so the built-in sum is insufficient for my needs. Here's my funtion: bool example(Zorba* aZorba) { XQuery_t lQuery = aZorba-compileQuery( "for $i in fn:doc('/tmp/products.xml')//time" "let $sum := xs:integer($i)" " return $sum" ); DynamicContext* lCtx = lQuery-getDynamicContext(); lCtx-setContextItemAsDocument("temp_measurements.xml", lDocStream); try { std::cout << lQuery << std::endl; } catch (DynamicException& e) { std::cerr << e.getDescription() << std::endl; return false; } catch (StaticException& f){ std::cerr << f.getDescription() << f.getErrorCodeAsString(f.getErrorCode()) << std::endl; return false; } } It's called with an appropriate main(). If I comment out the line that starts "let $sum..." then this works in that it returns the time values as a series of integers like this: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3.... Input file looks like this: <?xml version="1.0" encoding="UTF-8"? <temps <temp <time0</time <lat0</lat <long0</long <value0</value </temp <temp <time1</time <lat0</lat <long1</long <value0</value </temp ...
