1,093,319 | 0 | <p>Adding a ParentNode property to each node is "not really that bad". In fact, it's rather common. Apparently you didn't add that property because you didn't need it originally. Now you need it, so you have good reason to add it.</p> <p>Alternates include: </p> <ul> <li>Writing a function to find the parent of a child, which is processor intensive.</li> <li>Adding a separate class of some sort which will cache parent-child relationships, which is a total waste of effort and memory.</li> </ul> <p>Essentially, adding that one pointer into an existing class is a choice to use memory to cache the parent value instead of using processor time to find it. That appears to be a good choice in this situation.</p> |

924,834 | 0 | <p>You can use <code>Configure::read('Config.language')</code>. A part of the CakePHP cookbook states:</p> <blockquote> <p>The current locale is the current value of Configure::read('Config.language'). The value of Config.language is assigned in the L10n Class - unless it is already set.</p> </blockquote> <p>I18n, the class responsible for translation using <code>__()</code>, uses <code>Config.language</code> so, unless you override it in <code>bootstrap.php</code>, that variable contains the selected language. Actually, even if you override it, it will still contain the used language (there might be inconsistencies because I10n is not really aware of the change but I never ran into any).</p> <p>To get a list of languages, you can use <code>L10n::catalog()</code>. I'm not sure it's what you're after, however, since it lists all languages CakePHP knows about, not only the languages that actually have a translation in <code>app/locale</code>.</p> |
40,194,256 | 0 | <p>Your immediate problem is that you need parentheses around <code>(List.length xs)</code>. The code also treats an empty input list as an error in all cases, which is not correct. An empty list is a legitimate input if the desired length <code>k</code> is 0.</p> <p><strong>Update</strong></p> <p>You also have one extra parameter in your definition. If you say this:</p> <pre><code>let myfun k xs = function ... </code></pre> <p>the function <code>myfun</code> has 3 parameters. The first two are named <code>k</code> and <code>xs</code> and the third is implicitly part of the <code>function</code> expression.</p> <p>The quick fix is just to remove <code>xs</code>.</p> <p>I think you might be asking for the wrong number of elements in your recursive call to <code>take</code>. Something to look at anyway.</p> |

The post() method of a request handler is called on the event of a POST request. There can be several other methods in this class as well to handle different kinds of requests. Now notice what the post method does: It instantiates the Greeting class- we now have an instance, greeting object. Next, the "author" and "content" of the greeting object are set from the request information. Finally, greeting.put() writes to the database. Additionally, note that "date" is also set automatically to the date/time of writing the object to the database.</p> |

8,266,818 | 0 | <p>In iOS 5 you can use the UIAppearance protocol to set the appearance of all UINavigationBars in your app. Reference: <a href="http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UIAppearance_Protocol/Reference/Reference.html#//apple_ref/occ/intf/UIAppearance">link</a>.</p> <p>The way I got a solid color was to create a custom image for the navigation bar, and set it as UINavigationBars background. You might have to create the image with the same size as the UINavigationBar, at least that's what I did.</p> <p>In your app delegate, do something like this:</p> <pre><code>UIImage *image = [UIImage imageNamed:@"navbarbg.png"]; [[UINavigationBar appearance] setBackgroundImage:image forBarMetrics:UIBarMetricsDefault]; </code></pre> <p>You also have to add the <code>UIAppearanceContainer</code> protocol to the header file:</p> <pre><code>@interface AppDelegate : UIResponder <UIApplicationDelegate, UIAppearanceContainer> @end </code></pre> <p>You can probably achieve the same thing by setting some color or something, instead of an image.

1,491,029 | 0 | <p><strong>First:</strong> I would really re-check your original code for the conditions, while its possible there is a bug in the query optimizer its more likely there was a bug on the expression used and it really didn't represent the below:</p> <blockquote> <p>var DesiredList = db.Things.Where(t=> condition1 || (!condition1 && condition2));</p> <p>the problem is query optimizer seems to trim the expression to condition2 only.</p> </blockquote> <p>That should really give you the ones that match condition1 regardless of condition2 ... and ones that don't match condition1 and match condition2. Instead condition2 alone is not equivalent because that leaves out records that only match condition1. </p> <p>JS version of just (condition1 || condition2) is equivalent to the quoted expression above, as when u are matching condition1 you are already matching both condition2 and !condition2 so you are already including condition2 for both condition1 and !condition1 cases. If this doesn't match what you intended with the queries, is then clearer that's not an issue with the optimizer but with the original expressions.</p> <p>You would only need the full expressions if you were joining 2 results with a Concat instead of Union, as that would mean you would end up with results matching in both expressions ... and then you would have repeated results. But in contrast, the Where is evaluated per row, so you don't have those concerns in there.</p> <hr> <p><strong>Second:</strong> From the code sample, I think what you are facing is less direct of what you are going after in your question. You mentioned you are getting the first tag, but what you are really doing can be seen in this re-written version:</p> <pre><code>public static IQueryable<BookTag> UniqueByTags(this IQueryable<BookTag> bookTags, User user) { return bookTags.GroupBy(BT => BT.TagId) .Select(g => new BookTag() { User = g.Any(bt => bt.UserId == user.Id) ? user : g.First().User, Tag = g.First().Tag, Book = bookTags.First().Book }); } </code></pre> <p>What's mentioned in the comment seems more like:</p> <pre><code>public static IQueryable<BookTag> UniqueByTags(this IQueryable<BookTag> bookTags, User user) { return bookTags.GroupBy(BT => BT.TagId) .Select(g => g.Any(bt => bt.UserId == user.Id) ? g.First(bt=>bt.UserId == user.Id) : g.First() ); } </code></pre> |

15,164,620 | 0 | <p>Instead of trying to parse the output of <code>ls</code>, <a href="http://mywiki.wooledge.org/ParsingLs" rel="nofollow">which is bad</a>, you should simply use file system operation provided by node.js. Using file system operations you can be sure your program will work in (almost) any edge case as the output is well defined. It will even work in case the folder will contain more or less files than three in the future!</p> <p>As you stated in the comments that you want the names and date / time of the files from a folder. So let us have a look at:</p> <p><a href="http://nodejs.org/api/fs.html#fs_fs_readdir_path_callback" rel="nofollow"><code>fs.readdir(path, callback)</code></a>: <code>fs.readdir</code> will give you an array of filenames in the folder specified in path. You can pass them to <code>fs.stat</code> to find out the mtime:</p> <p><a href="http://nodejs.org/api/fs.html#fs_fs_fstat_fd_callback" rel="nofollow"><code>fs.stat(path, callback)</code></a>: <code>fs.stat()</code> will give you an object of <a href="http://nodejs.org/api/fs.html#fs_class_fs_stats" rel="nofollow"><code>fs.Stats</code></a> which contains the mtime in the <code>mtime</code> property.</p> <p>So your code will look something like this afterwards:</p> <pre><code>fs.readdir('dir', function (err, files) { for (var i = 0; i < files.length; i++) { (function () { var filename = files[i] fs.stat('dir/' + filename, function (err, stats) { console.log(filename + " was last changed on " + stats.mtime); }); })(); } }); </code></pre> <p>The output is:</p> <pre><code>[timwolla@~/test]node test.js 5 was last changed on Fri Mar 01 2013 20:24:35 GMT+0100 (CET) 4 was last changed on Fri Mar 01 2013 20:24:34 GMT+0100 (CET) 2 was last changed on Fri Mar 01 2013 20:24:33 GMT+0100 (CET) </code></pre> <p>In case you need a return value use the respective <code>Sync</code>-versions of these methods. These, however, will block your node.js eventing loop.</p> |
