  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

  • Multi choice form field in Django

    - by Dingo
    Hi! I'am developing application on app-engine-path. I would like to make form with multichoice (acceptably languages for user). Code look like this: Language settings: settings.LANGUAGES = ((u"cs", u"Ceština"), (u"en", u"English")) Form model: class UserForm(forms.ModelForm): first_name = forms.CharField(max_length=100) last_name = forms.CharField(max_length=100) languages = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=settings.LANGUAGES) The form is rendered o.k. (all languages have checkbox. IDs, NAMEs is ok.) But if I save some languages for user, those languages don't check checkboxes. User model look like this class User(User): #... languages = db.StringListProperty() #... and view: def edit_profile(request): user = request.user if request.method == 'POST': form = UserForm(request.POST) if form.is_valid(): # ... else: form = UserForm(instance=user) data = {"user":user, "form": form} return render_to_response(request, 'user_profile/user_profile.html', data)

    - by Lemo
    I want to know the best solution for this my case here is that i am taking values from Excel sheet and pushing them to database field, sometimes that field might contain some strings (thats why I cant make my object members int / double) In my class below size is the variable responsible for showing size of files in bytes public class dataNameValue { public string Name { get; set; } public string Count { get; set; } public string Size { get; set; } } I wanted to sort the list by file Size something like List mylist = new List(); mylist = mylist.OrderByDescending(i = i.Size).ToList(); The problem is that if i sorted it without converting it to "int/double" first -- its not giving right results

  • github url style

    - by Alex Le
    Hi all, I wanted to have users within my website to have their own URL like http://mysite.com/username (similar to GitHub, e.g. my account is http:// github. com/sr3d). This would help with SEO since every profile is under the same domain, as apposed to the sub-domain approach. My site is running on Rails and Nginx/Passenger. Currently I have a solution using a bunch of rewrite in the nginx.conf file, and hard-coded controller names (with namespace support as well). I can share include the nginx.conf here if you guys want to take a look. I wanted to know if there's a better way of making the URL pretty like that. (If you suggest a better place to post this question then please let me know) Cheers, Alex

  • Three20 - add items to launcherView after viewDidLoad

    - by lostInTransit
    Hi I am getting a list of image URLs and corresponding names at run time in my app. I would like to add these images to a TTLauncherView object that I have. Cannot add these in loadView. I am making a call to the method for getting my data in a separate thread. Once the thread completes, I add the TTLauncherItem objects to an array and set the "pages" variable of the LauncherView. But for some reason, the view is not updated and I don't see anything on it. Can someone please let me know how to refresh the launcherview after adding items to it in methods other than loadView? Thanks.

  • Maven: How to create assembly with snapshot artifacts without timestamps file name?

    - by marabol
    I've a repository containing snapshot artifacts with timestamps. I want to create an assembly, that contains the dependencies. This works fine. But the artifact names contains the timestamp. So i wonder how to remove the timestamp from filename for the assembly only. I've used this dependencySet: <outputFileNameMapping>${artifact.artifactId}-${artifact.version}.${artifact.extension}</outputFileNameMapping> But version seams to contain already the timestamp. So is there any chance to get a 1.1.1-SNAPSHOT instead of 1.1.1-20100323.071348-182?

  • How to demonstrate java multithreading visibility problems?

    - by Joe23
    If variables in Java are accessed from multiple threads, one must ensure that they are safely published. This usually means using synchronizedor volatile. I have got the impression, that some of my colleagues do not take this issue seriously, since they "never heard of volatile before and their programs have worked for years". So my question is: Can someone provide an example Java program/snippet, that reliably shows data visibility problems. I think running a program and seeing the unexpected NPE or stale variable value would help more, than just theoretic explanations, that cannot be demonstrated. Thanks a lot for your help!

  • Unit test with Authlogic on Rails 3

    - by Puru puru rin..
    Hello, I would like to write some unit test with a logged user using Authlogic. To start right, I used some code hosted in http://github.com/binarylogic/authlogic_example. But I get an error after rake test, because of "test_helper.rb" and the following class: class ActionController::TestCase setup :activate_authlogic end Here is my error: NameError: undefined local variable or method `activate_authlogic' for I think this Authlogic example is mapped over Rails 2; maybe it's a little bit different on Rails 3. Is there an other example where I can take example about unit test? Many thanks.

  • String replacement in PHP

    - by [email protected]
    This is my first question on this wonderful website. Lets say I have a string $a="some text..%PROD% more text" There will be just one %..% in the string. I need to replace PROD between the % with another variable content. So I used to do: $a = str_replace('%PROD%',$var,$a); but now the PROD between % started coming in different cases. So I could expect prod or Prod. So I made the entire string uppercase before doing replacement. But the side effect is that other letters in the original string also became uppercase. Someone suggested me to use regular expression. But how ? Thanks, Rohan

  • Vim: Call an ex command (set) from function?

    - by sixtyfootersdude
    Drawing a blank on this, and google was not helpful. Want to make a function like this: function JakPaste() let tmp = :set paste? if tmp == "paste" set nopaste else set paste endif endfunction map <F2> :call JakPaste()<CR> However this does not work. I have isolated the broken line: function JakPaste() let tmp = set paste? endfunction map <F2> :call JakPaste()<CR> Pressing F2 results in this error: Error detected while processing function JakPaste: line 1: E121: Undefined variable: set E15: Invalid expression: set paste? Hit ENTER or type command to continue How should I call an ex command (set) from a vim function? This seems somewhat relevant however I still don't get it.

  • ASP.net MVC - OneToOne relationship with pluralized nomenclature

    - by ludicco
    Hi, I have an OneToOne relationship between my models Account and Company the table names are Accounts and Companies respectively. Here is a brief screenshot of the structure: http://cl.ly/1AEU Everything works well, but mysteriously when I use the OneToOne associations I have accessors like: var db = new DB(); var account = db.Accounts.First(); var company = account.Companies; // note the plural not the singular accessor So, what's happing is that even if using OneToOne association, I still get the plural accessor with "companies" and not "company", if it this is a pure object representation and not an EntitySet generated in case when it s an oneToMany relationship. Is there a way to get this nomenclature to be applied properly? Thanks a lot

  • Using Parallel Extensions with ThreadStatic attribute. Could it leak memory?

    - by the-locster
    I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread locla storrage might be sensible to allow re-use of objects by worker threads. As such I was lookign at the ThreadStatic attribute which marks a static field/variable as having a unique value per thread. It seems to me that it would be unwise to use PE with the ThreadStatic attribute without any guarantee of thread re-use by PE. That is, if threads are created and destroyed to some degree would the variables (and thus objects they point to) remain in thread local storage for some indeterminate amount of time, thus causing a memory leak? Or perhaps the thread storage is tied to the threads and disposed of when the threads are disposed? But then you still potentially have threads in a pool that are longed lived and that accumulate thread local storage from various pieces of code the threads are used for. Is there a better approach to obtaining thread local storage with PE? Thankyou.

  • Why is my NSMutableArray returning nill?

    - by lampShade
    I have a very simple task: add the contents of a textField to an NSMutableArray.The Problem is the array is returning nill. I believe that it has something to do with the fact that the array I'm using is declared as an instance variable. /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { NSString *string = [textField stringValue]; NSLog(@"%@",string); [myArray addObject:string]; NSLog(@"%d",[myArray count]);//this outputs 0 why is that? }

  • R: ggplot2, how to add a number of layers to a plot at once to reduce code

    - by John
    library(ggplot2) This code produces a nice looking plot: qplot(cty, hwy, data = mpg, colour = displ) + scale_y_log2() + labs(x="x axis") + labs(y="y axis") + opts(title = "my title") But I want to setup variables to try and to reduce code repetition: log_scale <- scale_y_log2() xscale <- labs(x="x axis") yscale <- labs(y="y axis") title <- opts(title = "my title") my_scales <- c(log_scale, xscale, yscale, title) # make a variable to hold the scale info changes above So that I can do this and add a bunch of things at the same time: qplot(cty, hwy, data = mpg, colour = displ) + my_scales # add these to your plot. but I get this error: Error in object$class : $ operator is invalid for atomic vectors I realize that the things going into my_scales need to be layers / different types of objects, but I don't see what they should be.

  • Why is the form action attribute empty on production server?

    - by Ozzy
    After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action="" id="Form1"> However, on my developer machine I get the following: <form method="post" action="default.aspx" id="Form1"> So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly. Any suggestions or ideas would be helpful!

  • How do I check if a user is authenticated with NickServ using POE::Component::IRC::State in Perl?

    - by Troy
    I'm trying to test whether a user is registered on FreeNode. nick_info() doesn't seem to return information about this, so I want to use $irc-yield(whois = $nick); and then grab the irc_whois event's reply. The problem is that I want to wait until this event is fired, so I created a global variable $whois_result and wrote a sub like this: sub whois { my $nick = $_[0]; $whois_result = 0; $irc->yield(whois => $nick); while($whois_result == 0) { } return $whois_result; } with the irc_whois handler looking like: sub on_whois { $whois_result = $_[ARG0]; print "DEBUG: irc_whois fired.\n"; } Unfortunately, the event can't fire while the loop is running so this hangs. I'm sure there's a better way to do this, but I'm not familiar enough with this kind of programming to know. Any help would be greatly appreciated.

  • wpf manually generate TreeViewItem container

    - by viky
    I am creating a TreeView at runtime. It has several nodes(TreeViewItem), each one having a name. Initially it is collapsed. A separate comboBox displays Names of all TreeViewItem. I have to highlight a TreeViewItem based on the Name selected. I am using a recursive function and gets the TreeViewItem container like this: if (parent.ItemContainerGenerator.Status != GeneratorStatus.ContainersGenerated) continue; TreeViewItem container = parent.ItemContainerGenerator.ContainerFromItem(child).As<TreeViewItem>(); but it is parent.ItemContainerGenerator.Status = GeneratorStatus.NotStarted for all the collapsed items. How can I generate containers for them manually(Without expanding them)?

  • How do I avoid an infinite loop when overriding a virtual property?

    - by cbsch
    Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: virtual public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

  • Looping through JSON arrays

    - by George
    I'm trying to pull the field names in the header of some JSON output. The following is a sample of the JSON header info: {"HEADER":{"company":{"label":"Company Name"},"streetaddress":{"label":"Street Address"},"ceo":{"label":"CEO Name","fields":{"firstname":{"label":"First Name"},"lastname":{"label":"Last Name"}}} I'm able to loop through the header and output the field and label (i.e. company and Company Name) using the following code: obj = JSON.parse(jsonResponse); for (var key in obj.HEADER) { response.write ( obj.HEADER[key].label ); response.write ( key ); } but can't figure out how to loop through and output the sub array of fields (i.e. firstname and First Name). Any ideas?

  • NHibernate Criteria - How to filter on combination of properties

    - by DavGarcia
    I needed to filter a list of results using the combination of two properties. A plain SQL statement would look like this: SELECT TOP 10 * FROM Person WHERE FirstName + ' ' + LastName LIKE '%' + @Term + '%' The ICriteria in NHibernate that I ended up using was: ICriteria criteria = Session.CreateCriteria(typeof(Person)); criteria.Add(Expression.Sql( "FirstName + ' ' + LastName LIKE ?", "%" + term + "%", NHibernateUtil.String)); criteria.SetMaxResults(10); It works perfectly, but I'm not sure if it is the ideal solution since I'm still learning about NHibernate's Criteria API. What are the recommended alternatives? Is there something besides Expression.Sql that would perform the same operation? I tried Expression.Like but couldn't figure out how to combine the first and last names. Should I map a FullName property to the formula "FirstName + ' ' + LastName" in the mapping class? Should I create a read only FullName property on the domain object then map it to a column?

  • Python file-io code listing current folder path instead of the specified

    - by Tom Brito
    I have the code: import os import sys fileList = os.listdir(sys.argv[1]) for file in fileList: if os.path.isfile(file): print "File >> " + os.path.abspath(file) else: print "Dir >> " + os.path.abspath(file) Located in my music folder ("/home/tom/Music") When I call it with: python test.py "/tmp" I expected it to list my "/tmp" files and folders with the full path. But it printed lines like: Dir >> /home/tom/Music/seahorse-gw2jNn Dir >> /home/tom/Music/FlashXX9kV847 Dir >> /home/tom/Music/pulse-DcIEoxW5h2gz This is, the correct file names, but the wrong path (and this files are not either in my Music folder).. What's wrong with this code?

  • Internationalize HelloWorld program .NET

    - by RockStarInTraining
    I have small test app which has 2 resource files (Resources.resx & Resources.de-DE.resx) with the same exact string names, but one has the strings converted to German. For my form I set the Localize property to ture. In my application I am getting the strings as such: this.Text = Properties.Resources.frmCaption; In my release folder I get a de-DE folder with a dll named International_test.resources.dll. I try to distribute this to a machine which is set to German and all of the strings pulled are still english. I tried keeping the International_test.resources.dll in the de-DE folder or just put in in my apps directory. What am I doing wrong or what do I need to do to get the German resource file to be used?
