  • Doctrine: Relating a model to itself using a link table, like "This event is related to to the following other events"

    - by mattalexx
    So in English, the relationship would sound like "This event is related to to the following other events". My first instinct is to create an EventEvent model, with a first_event_id field and a second_event_id field. Then I would define the following two relationships in the Event model: $this->hasMany('Event as FirstRelatedEvents', array('local' => 'first_event_id', 'foreign' => 'second_event_id', 'refClass' => 'EventEvent')); $this->hasMany('Event as SecondRelatedEvents', array('local' => 'second_event_id', 'foreign' => 'first_event_id', 'refClass' => 'EventEvent')); But I would rather not have to use two relationships on the Event model. Is there a better way to do this?

  • Issue when I'm trying to draw gradient in swift

    - by bagusflyer
    I got an error when I was trying to draw gradient in Swift code: GradientView.swift:31:40: Could not find an overload for '__conversion' that accepts the supplied arguments Here is my code: let context : CGContextRef = UIGraphicsGetCurrentContext() let locations :CGFloat[] = [ 0.0, 0.25, 0.5, 0.75 ] let colors = [UIColor.redColor().CGColor,UIColor.greenColor().CGColor,UIColor.blueColor().CGColor, UIColor.yellowColor().CGColor] let colorspace : CGColorSpaceRef = CGColorSpaceCreateDeviceRGB() let gradient : CGGradientRef = CGGradientCreateWithColors(colorspace, colors, locations) //CGGradientCreateWithColors(colorspace,colors,locations) let startPoint : CGPoint = CGPointMake(0, 0) let endPoint : CGPoint = CGPointMake(500,500) CGContextDrawLinearGradient(context, gradient,startPoint, endPoint, 0); The problem is the CGGradientCreateWithColors takes CFArray not a normal Swift Array. I have no idea how to convert CFArray to Array and can't find anything in Apple's document. Any idea? Thanks

  • problems with url and email regex when searching text

    - by Grant Collins
    Hi, I'm having problems with regular expressions that I got from regexlib. I am trying to do a preg_replace() on a some text and want to replace/remove email addresses and URLs (http/https/ftp). The code that I am have is: $sanitiseRegex = array( 'email' => /'^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/', 'http' => '/^(http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*$/', ); $replace = array( 'xxxxx', 'xxxxx' ); $sanitisedText = preg_replace($sanitiseRegex, $replace, $text); However I am getting the following error: Unknown modifier '/' and $sanitisedText is null. Can anyone see the problem with what I am doing or why the regex is failing? Thanks

  • Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML

    - by phpwns
    Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML tables) generated with Javascript? An embarrassingly simple, though workable solution using Crowbar: <?php function get_html($url) // $url must be urlencode(d) { $context = stream_context_create(array( 'http' => array('timeout' => 120) // HTTP timeout in seconds )); $html = substr(file_get_contents('http://127.0.0.1:10000/?url=' . $url . '&delay=3000&view=browser', 0, $context), 730, -32); // substr removes HTML from the Crowbar web service, returning only the $url HTML return $html; } ?> The advantage to using Crowbar is that the tables will be rendered (and accessible) thanks to the headless mozilla-based browser. The problem, of course, is being dependent on on an external web service, especially given that SIMILE seems to undergo regular server maintenance. :( A pure php solution would be nice, but any functional (and reliable) alternatives would be great.

  • Breakdown of this Ruby code?

    - by randombits
    Would anyone be kind enough to dissect the merge! method? Its usage of conditions and variable assignment looks rather terse, and I'm having a difficult time following it.

  • How can I access and change elements in this private readonly property?

    - by CrimsonX
    I'm trying to figure out how I am able to successfully change a "readonly" array. I have this: namespace ConsoleApplication1 { class Program { static void Main(string[] args) { MyClass myClass = new MyClass(); myClass.Time[5] = 5; // How is this legal? } } public class MyClass { private readonly uint[] time; public IList<uint> Time { get { return time; } } public MyClass() { time = new uint[7]; } } } As I Note above, I would expect that Time[5] would be illegal due to the fact that public IList Time does not have a setter. Additionally, how can I create an array in the constructor which is read-only and unchangeable outside of this class?

  • Alter highchart output to display start - end date

    - by php_d
    I currently have the following highchart which display a start date and outputs the values for the next 31 days of data. Does anyone know how I may improve on this to include and end date so that I can filter the data by smaller specific amounts? On the x-axis I am also trying to only display labels that have data attached to them and hide any others. Any help is appreciated. My code is as follows: <script type="text/javascript"> var chart; $(document).ready(function() { chart = new Highcharts.Chart({ chart: { renderTo: 'container', type: 'line', marginRight: 130, marginBottom: 25 }, title: { text: '<?php echo $type ?>', x: -20 //center }, xAxis: { categories: [ <?php $start = $_POST["dateStart"]; $dates = array(); for ($i = 0, $days = date('t', strtotime($start)); $i < $days; ++$i) { $dates[] = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); } echo "'" . implode("', '", $dates) . "'"; ?> ] }, yAxis: { title: { text: 'Total Amount' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { formatter: function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; } }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -10, y: 100, borderWidth: 0 }, series: [ <?php foreach ($array as $legend => $data) { echo '{'; echo "name: '" . $legend . "',"; $values = array(); for ($i = 0; $i < $days; ++$i) { $date = date('Y-m-d', strtotime($start . ' + ' . $i . ' day')); $values[] = isset($data[$date]) ? $data[$date] : 0; } echo 'data: [' . implode(', ', $values) . '],'; echo '},'; } ?> ] }); }); Thanks

  • How to change Zend_Db_Table name within a Model to insert in multiple tables

    - by jwhat
    Using Zend Framework, I've created a Model to insert a record into a database. My question is, after $this->insert($data) how can I switch the active table so that I can insert a record into another table? Here's my code so far: class Model_DbTable_Foo extends Zend_Db_Table_Abstract { protected $_name = 'foo'; public function addFoo($params) { $data = array( 'foo' => $params['foo'], ); $this->insert($data); $foo_id = $this->getAdapter()->lastInsertId(); $data2 = array( 'bar' => $params['bar'] ); // I need to change the Db Table name here. $this->insert($data2); $bar_id = $this->getAdapter()->lastInsertId(); } }

  • How to delete refClass record in Doctrine?

    - by terrani
    Hi all! I have many-to-many relations with the following tables. post tag post_tag I created three classes with Doctrine, so I have the following classes as well. BasePost BaseTag BasePostTag in the setUp() method, I defined relations. I like to delete tag record when I delete post record. So I simply put cascade as descirbed on Doctrine document. $this->hasMany("Tag as Tags",array( 'refClass' => 'PostTag', 'local'=>'object_id', 'foreign'=>'tag_id', 'cascade'=> array('delete') )); it works without a problem. My questions is, how do I delete a record from post_tag table? Do I need to create a query myself?

  • Securing files on IPhone

    - by clearbrian
    Hi Is there a way to decompile the binary from an IPhone app. I jailbroke my IPhone and was surprised to find other app's dbs wide open to be copied. So I exported my most important table and hardcoded it into code. Instead of loading table into array from a db I just generated code to fill the array and kept only the most basic DB info so relationships still work. Took a while but now works fine. I was just wondering am I safe, could someone decompile the binary for the app easily and extract the data. In Java its easy to decompile *.class files though thats bytecode where I presume iphone apps are more low level. I know IPhone sdk 4 can mark files as secure. Anyone know can this be overridden by jailbreaks or is this an unix lock?

  • Testing for the existence of a field in a class

    - by Brett
    Hi, i have a quick question. I have a 2D array that stores an instance of a class. The elements of the array are assigned a particular class based on a text file that is read earlier in the program. Since i do not know without looking in the file what class is stored at a particular element i could refer to a field that doesn't exist at that index (referring to appearance when an instance of temp is stored in that index). i have come up with a method of testing this, but it is long winded and requires a second matrix. Is there a function to test for the existence of a field in a class? class temp(): name = "default" class temp1(): appearance = "@"

  • NSArraycontroller selectionIndexes bindings

    - by Michael Scherbaum
    Hi all, I have the following set-up: A Window that has a splitView in which I display I NSCollectionView in the left view and a detailView in the right view. Both views are set-up in separate xibs. Furthermore I have a Datacontroller (of class NSArrayController) that manages a mutable Array of NSMutableDictionaries (moviesForChoice). The dataController is set-up as application delegate. The movie objects in the array have properties like (name, plot, genre etc.) so far so good... In the xib for the NScollectionview I bound a NSArraycontroller content property to my datacontroller via Application.delegate.moviesForChoice The collectionView accesses the arraycontroller.arrrangedObjects and arraycontroller.selectionIndexes. This works fine the contents are displayed and the selection works fine in the collectionview (my collectionviewItem renders a selection color) In the xib for the detailView I want to display information for the selected object in the collectionview. Therefore I also added an arraycontroller to the xib, bound the content aray to Application.delegate.moviesForChoice and bound the NSTextfields in the view to e.g. arraycontroller.selection.name Here comes my issue: everytime I open the window with the two xibs, my collectionview displays all movies that are for choice correctly, and the detailview displays the information for the 1st object in my collectionview. Whenever I click on a different movie in the collectionView the res. item renders a selection color, but the detailView doesn't update. My understanding of it would be that the DataController is not informed about updates in the selectionIndexes and can therefore not trigger an update in the detailView. Correct me if I'm wrong... To remedy this I tried to bind the selectionIndexes property of the arraycontroller in the collectionView xib to Application.delegate.moviesForChoice.selecionIndexes but this failed with: addObserver:forKeyPath:options:context:] is not supported. Key path: selectionIndexes I could imagine that this means that the datacontroller is not KVO compliant for my Array moviesForChoice, but I implemented the following methods for it: -(void)insertObject:(NSDictionary *)dict inMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice insertObject:dict atIndex:index]; } -(void)removeObjectFromMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice removeObjectAtIndex:index]; } -(void)setMoviesForChoice:(NSMutableArray *)a { moviesForChoice = a; } -(NSArray*)moviesForChoice { return moviesForChoice; } -(NSUInteger)countOfMoviesForChoice { return [moviesForChoice count]; } - (void)addMovieForChoiceObject:(Movie *)anObject { [moviesForChoice addObject:anObject]; } So where am I wrong? How do I correctly bind to the selectionIndexes? You help is much appreciated! M

  • PHP - Get dates of next 5 weekdays?

    - by Dan
    I'm trying to create an array of the next 5 working week days (Monday - Friday, excluding today). I know the working week varies around the world but this is not important for what I am trying to do. So, for example, if today is a Wednesday, I want the dates for Thursday and Friday of the current week and Monday, Tuesday and Wednesday of the following week. I thought this would work: $dates = array(); for ($i = 1; $ < 6; $i ++) { $dates[] = date('Y-m-d', strtotime('+ '.$i.' weekday')); } But for today, it is giving me: Monday 1st Tuesday 2nd Wednesday 3rd Thursday 4th Sunday 7th! Any advice appreciated. Thanks

  • How does PHP's list function work?

    - by Jacob Relkin
    After recently answering a couple of questions here on SO that involved utilizing PHP's list function, I wondered, "how in the world does that function actually work under the hood?". I was thinking about something like using func_get_args() and then iterating through the argument list, and that's all nice and peachy, but then how in the world does the assignment part work? list(...) = array($x, $y, $z); isn't this ^ evaluated first? So to be precise, my question is how is the list function able to create scoped variables which get assigned to the not-yet evaluated array?

  • Iterate set covered by cross-product of ranges in ruby

    - by wilsona
    I figured this answer had been asked before, so I searched, but I couldn't find anything. Granted, there are a ton of Ruby Array questions, so it might be there, just buried. In any case, I'm trying to reduce a cross-product of ranges, returning a sum of all elements of the cross-product that meet some set of conditions. To construct a trivial example, if I have an array like this: [0..1,0..1,0..1] I'd like to iterate over this set: [ [0,0,0], [0,0,1], [0,1,0], [0,1,1], [1,0,0], [1,0,1], [1,1,0], [1,1,1] ] and return a sum based the condition "return 1 if i[0] == 1 and i[2] == 0" (which would give 2). In my contrived example, I could do it like this: br = 0..1 br.reduce(0){|sumx, x| sumx + br.reduce(0){|sumy, y| sumy + br.reduce(0){|sumz, z| sumz + (x == 1 and z == 0 ? 1 : 0) } } } , but in the actual application, the set of ranges might be much larger, and nesting reduces that way would get quite ugly. Is there a better way?

  • foreach: how to iterate this

  • Chart Filtering

    - by Tim Dexter
    Interesting question from a colleague this week. Can you add a filter to a chart to just show a specific set of data? In an RTF template, you need to do a little finagling in the chart definition. In an online template, a couple of clicks and you're done. RTF Build your chart as you would normally to include all the data to start with. Now flip to the Advanced tab to see the code behind the chart. Its not very pretty but with a little effort you can get it looking a little more friendly. Here's my chart showing employees and their salaries. <Graph depthAngle="50" depthRadius="8" seriesEffect="SE_AUTO_GRADIENT"> <LegendArea visible="true"/>  <Title text="Executive Department Only" visible="true" horizontalAlignment="CENTER"/>  <LocalGridData colCount="{count(.//G_2)}" rowCount="1">   <RowLabels>    <Label>SALARY</Label>   </RowLabels>   <ColLabels>    <xsl:for-each select=".//G_2">     <Label><xsl:value-of select="EMP_NAME"/></Label>    </xsl:for-each>   </ColLabels>   <DataValues>    <RowData>     <xsl:for-each select=".//G_2">      <Cell><xsl:value-of select="SALARY"/></Cell>     </xsl:for-each>    </RowData>   </DataValues>  </LocalGridData> </Graph> Note the emboldened text. Its currently grabbing all values in the G_2 level of the data. We can use an XPATH expression to filter the data to the set we want to see. In my case I want to only see the employees that are in the Executive department. My  data is structured thus:   <DATA_DS>     <G_1>         <DEPARTMENT_NAME>Accounting</DEPARTMENT_NAME>         <G_2>             <MANAGER>Higgins</MANAGER>             <EMPLOYEE_ID>206</EMPLOYEE_ID>             <HIRE_DATE>2002-06-07T00:00:00.000-04:00</HIRE_DATE>             <SALARY>8300</SALARY>             <JOB_TITLE>Public Accountant</JOB_TITLE>             <PARAS>11000</PARAS>             <EMP_NAME>William Gietz</EMP_NAME>         </G_2> So the XPATH expression Im going to use to limit the data to the Executive department would be .//G_2[../DEPARTMENT_NAME='Executive'] Note the ../ moves the parser up the XML tree to be able to test the DEPARTMENT_NAME value. I added this XPATH expression to the three instances that need it ColCount, ColLabels and RowData. Its simple enough to do. Testing your XPATH expression is easier to do using a table of data. Please note, as soon as you make changes to the chart code. Going back to the Builder tab, you'll find that everything is grayed out. I recommend you make all the changes you can via the chart dialog before updating the code. Online Template Implementing the filter is much simpler, there is a dialog box to help you out. Add you chart and fill out the various data points you want to show. then hit the Filter item in the ribbon above the chart. That will pop the filter dialog box where you can then add a filter to the chart.   You can add multiple filters if needed and of course you can use the Manage Filters button to re-open and edit the filters. Pretty straightforward stuff!

  • PHP echo query result in Class??

    - by Jerry
    Hi all I have a question about PHP Class. I am trying to get the result from Mysql via PHP. I would like to know if the best practice is to display the result inside the Class or store the result and handle it in html. For example, display result inside the Class class Schedule { public $currentWeek; function teamQuery($currentWeek){ $this->currentWeek=$currentWeek; } function getSchedule(){ $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } $scheduleQuery=mysql_query("SELECT guest, home, time, winner, pickEnable FROM $this->currentWeek ORDER BY time", $connection); if (!$scheduleQuery){ die("database has errors: ".mysql_error()); } while($row=mysql_fetch_array($scheduleQuery, MYSQL_NUMS)){ //display the result..ex: echo $row['winner']; } mysql_close($scheduleQuery); //no returns } } Or return the query result as a variable and handle in php class Schedule { public $currentWeek; function teamQuery($currentWeek){ $this->currentWeek=$currentWeek; } function getSchedule(){ $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } $scheduleQuery=mysql_query("SELECT guest, home, time, winner, pickEnable FROM $this->currentWeek ORDER BY time", $connection); if (!$scheduleQuery){ die("database has errors: ".mysql_error()); // create an array } $ret = array(); while($row=mysql_fetch_array($scheduleQuery, MYSQL_NUMS)){ $ret[]=$row; } mysql_close($scheduleQuery); return $ret; // and handle the return value in php } } Two things here: I found that returned variable in php is a little bit complex to play with since it is two dimension array. I am not sure what the best practice is and would like to ask you experts opinions. Every time I create a new method, I have to recreate the $connection variable: see below $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } It seems like redundant to me. Can I only do it once instead of calling it anytime I need a query? I am new to php class. hope you guys can help me. thanks.

  • Split a map using Groovy

    - by Tihom
    I want to split up a map into an array of maps. For example, if there is a map with 25 key/value pairs. I want an array of maps with no more than 10 elements in each map. How would I do this in groovy? I have a solution which I am not excited about, is there better groovy version: static def splitMap(m, count){ if (!m) return def keys = m.keySet().toList() def result = [] def num = Math.ceil(m?.size() / count) (1..num).each { def min = (it - 1) * count def max = it * count > keys.size() ? keys.size() - 1 : it * count - 1 result[it - 1] = [:] keys[min..max].each {k -> result[it - 1][k] = m[k] } } result } m is the map. Count is the max number of elements within the map.
