  • Rails Plugin - Install as Plugin or Install As Gem

    - by Joseph Misiti
    Hey guys, I am new to rails and have a question regarding the plugins. It seems there are two approaches you can take when using a third party plugin in a ROR App: 1) install a gem using sudo gem install GEM, and then "require" it in your rails project 2) install the plugin using script/generate plugin install PLUGIN. The plugin in code appears in your vendor directory and then you are good to go (sometimes, i could not get Devise working via this method). Since it appears both of these methods accomplish them same thing, why should I choose one method over the other. Thanks,

  • Linq PredicateBuilder with conditional AND, OR and NOT filters.

    - by richeym
    We have a project using LINQ to SQL, for which I need to rewrite a couple of search pages to allow the client to select whether they wish to perform an and or an or search. I though about redoing the LINQ queries using PredicateBuilder and have got this working pretty well I think. I effectively have a class containing my predicates, e.g.: internal static Expression<Func<Job, bool>> Description(string term) { return p => p.Description.Contains(term); } To perform the search i'm doing this (some code omitted for brevity): public Expression<Func<Job, bool>> ToLinqExpression() { var predicates = new List<Expression<Func<Job, bool>>>(); // build up predicates here if (SearchType == SearchType.And) { query = PredicateBuilder.True<Job>(); } else { query = PredicateBuilder.False<Job>(); } foreach (var predicate in predicates) { if (SearchType == SearchType.And) { query = query.And(predicate); } else { query = query.Or(predicate); } } return query; } While i'm reasonably happy with this, I have two concerns: The if/else blocks that evaluate a SearchType property feel like they could be a potential code smell. The client is now insisting on being able to perform 'and not' / 'or not' searches. To address point 2, I think I could do this by simply rewriting my expressions, e.g.: internal static Expression<Func<Job, bool>> Description(string term, bool invert) { if (invert) { return p => !p.Description.Contains(term); } else { return p => p.Description.Contains(term); } } However this feels like a bit of a kludge, which usually means there's a better solution out there. Can anyone recommend how this could be improved? I'm aware of dynamic LINQ, but I don't really want to lose LINQ's strong typing.

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • Navigation bar's buttons tint color sometimes not set

    - by Felipe
    Refer to the following, short video: http://screencast.com/t/cmnsqVTh The problem is with the color of a navigation bar's back button. The first time I load the app, the navigation bar + its buttons have the default color. I then push a view controller on the stack, and when the new view loads (in the viewDidLoad method), it sets the navigation bar's tint color to pink. The nav bar's buttons are also pink as expected. I then press the back button, and the view is popped from the stack. On the root view controller's viewWillAppear method I set the tint color back to nil so that it's the default color again. The navigation bar looks as expected. However if I push the view controller on the stack yet again, the navigation bar's tint color is pink, but the back button's color is the default light blue. Hope that was understandable. So what's the cause of the problem?

  • How to change to a grouped table view in xcode without using Interface Builder

    - by Dave
    I have a table that I created within xcode so there is no nib file in this case. I want to make my table into the 'Grouped' style but im not sure how. I think it has somthing to do with the method below, the problem is Im not really sure how to call it, I do understand how methods work I'm just not too sure on where to start with this one: - (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)UITableViewStyleGrouped So could someone tell me how to call it? The problem is that its not a method I wrote its a built in one so I could put that line into my header file but how would I use it in my implementation file? Thanks guys,

  • Eye Detection Problem In Opencv

    - by iva123
    Hi, I'm trying to convert this c code(http://nashruddin.com/OpenCV_Eye_Detection) to the python code, but in c style, he used cvROI thing, since ROI functions are not supported by python-opencv, I tried cvGetSubRect so Here is the eye detection part of the code : eye_region = cvGetSubRect(image,cvRect(face.x,int(face.y + (face.height/4)),face.width,int(face.height/2))) eyes = cvHaarDetectObjects(eye_region,eyeCascade,memo,1.15,3,0,cvSize(25,15)) for e in eyes: cvRectangle(image, cvPoint( int(e.x), int(e.y)), cvPoint(int(e.x + e.width), int(e.y + e.height)), CV_RGB(0, 255, 0), 1, 8, 0) return image; When I run this code, It draws rectangles irrelevant places. I thought, eye_region coordinates are wrong, and tried some coordinates, but it didn't work. Any idea ? Note :Face detection method works very well, and it's code is same with the eye detection method.

  • Install a vimball from the command line.

    - by Robert Massaioli
    As this post points out you can install Vimballs using the normal: vim somevimball.vba :so % :q But if you want to install a from the command line how do you do it? I ran a 'man vim' and it seems like the best "from source install" option was the '-S' option so I tried to install haskellmode with it: wget 'http://projects.haskell.org/haskellmode-vim/vimfiles/haskellmode-20090430.vba' vim -S haskellmode-20090430.vba and that failed to work. It gave me the following error: Error detected while processing function vimball#Vimball: line 10: (Vimball) The current file does not appear to be a Vimball! press ENTER or type command to continue It should be noted that using the first method I was able to successfully install the vimball. I have tried the second method on a few other vimballs and it has failed every time. Is there a way to install a vimball from the command line? It seems like a useful sort of task. Oh, and I am running the following version of vim: Version: 2:7.2.330-1ubuntu3 Thanks.

  • Capturing WPF Listbox checkbox selection

    - by wonea
    Been trying to figure out, how do I capture the events from a listbox. In the template, I've added the parameter IsChecked="" which starts my method. However, the problem is trying to capture what has been checked in the method. SelectedItem only returns what is currently selected, not the checkbox. object selected = thelistbox.SelectedItem; DataRow row = ((DataRowView)selected).Row; string teststring = row.ItemArray[0].ToString(); // Doesn't return the checkbox! <ListBox IsSynchronizedWithCurrentItem="True" Name="thelistbox" ItemsSource="{Binding mybinding}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <CheckBox Content="{Binding personname}" Checked="CheckBox_Checked" Name="thecheckbox"/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

  • How to map hash keys to methods for an encapsulated Ruby class (tableless model)?

    - by user502052
    I am using Ruby on Rails 3 and I am tryng to map a hash (key, value pairs) to an encapsulated Ruby class (tableless model) making the hash key as a class method that returns the value. In the model file I have class Users::Account #< ActiveRecord::Base def initialize(attributes = {}) @id = attributes[:id] @firstname = attributes[:firstname] @lastname = attributes[:lastname] end end def self.to_model(account) JSON.parse(account) end My hash is hash = {\"id\":2,\"firstname\":\"Name_test\",\"lastname\":\"Surname_test\"} I can make account = Users::Account.to_model(hash) that returns (debugging) --- id: 2 firstname: Name_test lastname: Surname_test That works, but if I do account.id I get this error NoMethodError in Users/accountsController#new undefined method `id' for #<Hash:0x00000104cda410> I think because <Hash:0x00000104cda410> is an hash (!) and not the class itself. Also I think that doing account = Users::Account.to_model(hash) is not the right approach. What is wrong? How can I "map" those hash keys to class methods?

  • C Programming: malloc and free within a loop

    - by kouei
    Hi all, I just started out with C and have very little knowledge about performance issues with malloc() and free(). My question is as such: if I were to call malloc() followed by free() in a while-loop that loops for, say, 20 times, would it run slower compared to if I were to call free() outside the loop? I am actually using the first method to allocate memory to a buffer, read a string of variable length in a file, perform some string operation, and then clear the buffer after every iteration. If my method results in a lot of overhead then I'd like to ask for a better way for me to achieve the same results. Sorry for my bad English. Thanks and regards, K

  • NSOperation and UIKit problem

    - by Infinity
    Hello guys! I am doing my download with an object which was inherited from NSOperation. I have read the documentation and when my operation finished I must call the [self.delegate performSelectorOnMainThread:@selector(operationDidFinish:) withObject:self waitUntilDone:YES]; method. It needs to be called on the main thread, because the UIKit is not thread safe and the documentation says this in these non thread safe frameworks cases. In the delegate method I am drawing a pdf or an image, but because it is drawn on the main thread the User Interface is very laggy until the drawing is finished. Maybe can you suggest me a good way to avoid this problem?

  • How do I give each test its own TestResults folder?

    - by izb
    I have a set of unit tests, each with a bunch of methods, each of which produces output in the TestResults folder. At the moment, all the test files are jumbled up in this folder, but I'd like to bring some order to the chaos. Ideally, I'd like to have a folder for each test method. I know I can go round adding code to each test to make it produce output in a subfolder instead, but I was wondering if there was a way to control the output folder location with the Visual Studio unit test framework, perhaps using an initialization method on each test class so that any new tests added automatically get their own output folder without needing copy/pasted boilerplate code?

  • JMenuBar dropping down to a "custom" JPanel and "erased"

    - by Jani
    The JMenuItems of JMenuBar drops down to a JPanel added to the JFrame, but the JPanel erases the JMenuItems. Do I supposed to pause the re-drawing of the JPanel? I'm using getGraphics() on the JPanel for drawing an image, this method is called from a thread with (for example) 200 ms delay. edit: It's a (very simple) game inside the JPanel. (I've added a field "paused" to the JPanel and i've edited the paint method so it repaints the JPanel only if paused is false, however I don't know if this "solution" is good. (It's set to true when the user clicks on a menu and set to false when selects or cancels it.)

  • JDBC Realm: GlassFish v2.1 = OK; GlassFish v3 = fail with invaliduserreason

    - by Vik Gamov
    In my J2EE 5 application I have a JDBC Realm based security with Form method. Encrypt method is MD5 as default. The database is PostgreSQL 8.4 installed locally (or 8.3 available via lan). My app used to work finely on GlassFish v2.1 server with PostgreSQL 8.3, but now I need to deploy it on GlassFish v3. I am absolutely sure I have done all the same config on GFv3 like creating Connection Pool (which pings with no problem), JDBC Resource and JDBC Realm. But on GFv3 I get login exception with "invaliduserreason" while the database schema is just created from the working database script. I have checked the data and entered login/password thousand times and it seems that data is all right. So where can I find the reason of unworking security? Please, advice. NetBeans 6.8 Thanks.

  • ASP.NET MVC TDD with LINQ and SQL database

    - by dean nolan
    I am trying to start a new MVC project with tests and I thought the best way to go would have 2 databases. 1 for testing against and 1 for when I run the app and use it (also test really as it's not production yet). For the test database I was thinking of putting create table scripts and fill data scripts within the test setup method and then deleting all this in the tear down method. I am going to be using Linq to SQL though and I don't think that will allow me to do this? Will I have to just go the ADO route if I want to do it this way? Or should I just use a mock object and store data as an array or something?. Any tips on best practices? How did Jeff go about doing this for StackOveflow?

  • Convert XMLDocument to String

    - by mnh
    Here is how I'm currently converting XMLDocument to String StringWriter stringWriter = new StringWriter(); XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter); xmlDoc.WriteTo(xmlTextWriter); return stringWriter.ToString(); The problem with this method is that if I have " ((quotes) which I have in attributes) it escapes them. For Instance: <Campaign name="ABC"> </Campaign> Above is the expected XML. But it returns <Campaign name=\"ABC\"> </Campaign> I can do String.Replace "\" but is that method okay? Are there any side-effects? Will it work fine if the XML itself contains a "\"

  • How to use delegate to perform callback between caller and web service helper class?

    - by codemonkie
    I have 2 classes A and B, where they belongs to the same namespace but resides in seperate files namely a.cs and b.cs, where class B essentially is a helper wrapping a web service call as follow: public class A { public A() // constructor { protected static B b = new B(); } private void processResult1(string result) { // come here when result is successful } private void processResult2(string result) { // come here when result is failed } static void main() { b.DoJobHelper(...); } } public class B { private com.nowhere.somewebservice ws; public B() { this.ws = new com.nowhere.somewebservice(); ws.JobCompleted += new JobCompletedEventHandler(OnCompleted); } void OnCompleted(object sender, JobCompletedEventArgs e) { string s = e.Result; Guid taskID = (Guid)e.UserState; switch (s) { case "Success": // Call processResult1(); break; case "Failed": // Call processResult2(); break; default: break; } } public void DoJobHelper() { Object userState = Guid.NewGuid(); ws.DoJob(..., userState); } } (1) I have seen texts on the net on using delegates for callbacks but failed to apply that to my case. All I want to do is to call the appropriate processResult() method upon OnCompleted() event, but dunno how to and where to declare the delegate: public delegate void CallBack(string s); (2) There is a sender object passed in to OnCompleted() but never used, did I miss anything there? Or how can I make good use of sender? Any helps appreciated.
