  • Django Form Preview

    - by Mark Kecko
    I'm trying to use django's FormPreview and I can't get it to work properly. Here's my code: forms.py class MyForm(forms.ModelForm): status = forms.TypedChoiceField( coerce=int, choices=LIST_STATUS, label="type", widget=forms.RadioSelect ) description = forms.CharField(widget = forms.Textarea) stage = forms.CharField() def __init__(self, useradd=None, *args, **kwargs): super(MyForm, self).__init__(*args, **kwargs) self.fields['firm'].label = "Firm" class Meta: model = MyModel fields = ['status', 'description', 'stage'] class MyFormPreview(FormPreview): form_template = 'templates/post.html' preview_template = 'templates/review.html' def process_preview(self, request, cleaned_data): print "processed" def done(self, request, cleaned_data): print "done" # Do something with the cleaned_data, then redirect # to a "success" page. return HttpResponseRedirect('/') urls.py (r'^post/$', MyFormPreview(MyForm)), post.html <form id = "post_ad" action = "" method = "POST" enctype="multipart/form-data"> <table> {{form.as_table}} </table> <input type="submit" name="save" value="Post" /> </form> When I go to /post/ I get the correct form and I fill it out. When I submit the form it goes right back to /post/ but but there are no errors (I've tried displaying {{errors}}) and the form is empty. None of my print statements execute. I'm not sure what I'm missing. Can anyone help me out? I can't find any documentation besides what's on the django site. Also, what's the "preview" variable called that I should use in my preview.html template? {{preview}} or do I just do {{form}} again? -- Answered below. I tried adding 'django.contrib.formtools' to my installed_apps in settings and I tried using the code from the default form templates from django.contrib as suggested below. Still, when I submit the form I go right back to the post template, none of my print statements execute :(

  • AVAudioPlayer via Speakers

    - by Mark
    I got the following code: - (id)init { if (self = [super init]) { UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback; AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory); UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride); [[AVAudioSession sharedInstance] setDelegate:self]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; [[AVAudioSession sharedInstance] setActive:YES error:nil]; } return self; } But somehow the sound does not want to come out of the speakers, can someone see what I am doing wrong? The code I use for playing is: AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFilePathURL error:nil]; [player prepareToPlay]; [player setVolume:1.0]; [player play];

  • Dynamically Added CheckBox Column is Disabled in GridView

    - by Mark Maslar
    I'm dynamically adding a Boolean column to a DataSet. The DataSet's table is the DataSource for a GridView, which AutoGenerates the columns. Issue: The checkboxes for this dynamically generated column are all disabled. How can I enable them? ds.Tables["Transactions"].Columns.Add("Retry", typeof(System.Boolean)); ds.Tables["Transactions"].Columns["Retry"].ReadOnly = false; In other words, how can I control how GridView generates the CheckBoxes for a Boolean field? (And why does setting ReadOnly to False have no effect?) Thanks!

  • [ASP.NET ERROR] The request was aborted: Could not create SSL/TLS secure channel.

    - by Mark Cidade
    I'm posting this on behalf of a co-worker. He gets a "The request was aborted: Could not create SSL/TLS secure channel" error while using a WebRequest object to make an HTTPS request. Th funny thing is that this only happens after a while, and is temporarily fixed when the application is restarted, which suggests that something is being filled to capacity or something. Has anyone seen this kind of thing before?

  • Using GKPeerPickerController within a selector from a Cocos2D CCMenuItem

    - by Mark Hazlett
    Hey everyone, So i'm trying to use GameKit along with Cocos2D so that when a user clicks on the multiplayer menu item it will display the GKPeerPickerController. I'm however, running into some snags. It doesn't seem to want to compile. However, it doesn't give me an error inside of the code that's in my selector. Anyways here's the code... @implementation GameOverLayer - (id) init { self = [super init]; if (self != nil) { [CCMenuItemFont setFontSize:20]; [CCMenuItemFont setFontName:@"Helvetica"]; CCMenuItem *start = [CCMenuItemFont itemFromString:@"Play Again!" target:self selector:@selector(startGame:)]; CCMenuItem *connect = [CCMenuItemFont itemFromString:@"Multiplayer" target:self selector:@selector(connect:)]; CCMenu *menu = [CCMenu menuWithItems:start,connect, nil]; [menu alignItemsVertically]; [self addChild:menu]; } return self; } -(void)startGame: (id)sender { [[CCDirector sharedDirector] replaceScene: [HelloWorld scene]]; } -(void)connect: (id)sender { GKPeerPickerController *peerPicker; peerPicker = [[GKPeerPickerController alloc] init]; peerPicker.delegate = self; peerPicker.connectionTypesMask = GKPeerPickerConnectionTypeOnline | GKPeerPickerConnectionTypeNearby; [peerPicker show]; } @end The error message i'm getting is... ".obj_class_name_GKPeerPickerController", referenced from: Literal-Pointer@_OBJC@_cls_refs@GKPeerPickerController in GameOverScene.o Symbol(s) not found Collect2: id returned 1 exit status Any ideas?

  • How to create minidump of a .NET process when a certain first chance exception occurs.

    - by mark
    Dear ladies and sirs. My application throws InvalidCastException in the QA environment, something I cannot reproduce in development. I wish to obtain the minidump at the exception moment. I know about adplus, but I am not sure how to use it so that it creates the minidump when InvalidCastException is thrown. Apparently, it does not distinguish one .NET exception from another. May be I am wrong and there is a way. Or, there is another tool to do it. Preferably free one. Anyway, can anyone advice how to handle this issue? Thanks. UPDATE The build is a Debug build in both QA and dev. However, QA runs complex scenarios made possible in the lab, which devs cannot reproduce. Hence I need an ability to make dump when running in QA. I can modify the code and create minidump from code. However, I wish for a more flexible solution, the one not requiring to modify the code every time an issue like this occurs.

  • Django formsets: make first required?

    - by Mark
    These formsets are exhibiting exactly the opposite behavior that I want. My view is set up like this: def post(request): # TODO: handle vehicle formset VehicleFormSetFactory = formset_factory(VehicleForm, extra=1) if request.POST: vehicles_formset = VehicleFormSetFactory(request.POST) else: vehicles_formset = VehicleFormSetFactory() And my template looks like this: <div id="vehicle_forms"> {{ vehicles_formset.management_form }} {% for form in vehicles_formset.forms %} <h4>Vehicle {{forloop.counter}}</h4> <table> {% include "form.html" %} </table> {% endfor %} </div> That way it initially generates only 1 form, like I want. But I want that one form to be required! When I dynamically add blank forms with JavaScript and vehicles_formset.empty_form all those extra forms are required, which I don't want. From the docs: The formset is smart enough to ignore extra forms that were not changed. This is the behavior the first form is exhibiting (not what I want) but not the behavior that the extra forms are exhibiting (what I do want). Is there some attribute I can can change to at least make one form required?

  • Unexpected JAXB error

    - by Mark Lewis
    Hello, From the documentation it's clear I need to use the following to get a simple unmarshalling to occur from my XML file/schema: JAXBContext jc = JAXBContext.newInstance("PackageName"); where PackageName is my package name. I've looked on google for a bit to no avail, to find out why I'm then getting this runtime error: Line:Col[2:142]:cvc-elt.1: Cannot find the declaration of element 'myconfig'. Line:Col[2:142]:unexpected element (uri:"http://www.w3.org", local:"myconfig"). Expected elements are <{}myconfig> Caught UnmarshalException This occurs at the top of all my class files, including the ones the XJC plugin for eclipse created for me (which I then moved out of PackageName.PackageName which it automatically created): package PackageName; so why is this error occurring?

  • Operand size conflict in x86 Assembly??

    - by Mark V.
    I'm a novice programmer who is attempting assembly for the first time. Sorry in advance if this is an incredibly lame question. I have a character stored in the EAX register, but I need to move it to my DL register. When I try: mov dl, eax I get an error C2443: operand size conflict. I know that the eax register is 32 bit while the dl is 8 bit... am I on to something?? How do I go about solving this.

  • iPhone MKMapView force callout bubble

    - by Mark
    Is it possible to force the call out bubble to be open all the time? I tried putting the following code in didAddAnnotionViews: for (id<MKAnnotation> currentAnnotation in mapView.annotations) { [mapView selectAnnotation:currentAnnotation animated:NO]; } Which works, however, when I single tap the MKMapView the bubble disappear. I want to avoid this behavior.

  • What type of things can cause sgen msbuild task to fail intermittantly with Access Violation?

    - by Mark Allanson
    In our MSBuild file for our project we sgen an assembly containing classes used during xml serialization. The classes are generated via xsd.exe. We use the following SGen task configuration. <SGen ToolPath="$(SdkPath)" ShouldGenerateSerializer="true" UseProxyTypes="false" BuildAssemblyName="AssemblyName.dll" BuildAssemblyPath="Outputs" ContinueOnError="false" /> Intermittantly the following error is thrown when executing the msbuild script on our build server. Originally this error might have occurred once out of every 50 (CI) builds, recently the frequency has been increasing and it now occurs maybe 5-6 out of every 10 builds. The size of the assembly that is being Sgenned is about 410k (circa 35,000 lines of generated code), and when successfull the serialization assembly is about 1.7M in size. When it fails, the output is as follows: Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. E:\Path_ToBuild_Workspace\SolutionBuild.MSBuild(74,5): error MSB6006: "sgen.exe" exited with code -1073741819. We are using Hudson to manage our builds, so the msbuild and sgen processes are therefore spwaned by the Hudson.exe. There's not much out there on the interwebs regarding this type of error from SGen. Certainly nothing concrete.

  • How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?

    - by Mark Lindell
    I'm using VS1010RC with the POCO self tracking T4 templates. In my WCF update service method I am using something similar to the following: using (var context = new MyContext()) { context.MyObjects.ApplyChanges(myObject); context.SaveChanges(); } This works fine until I set ConcurrencyMode=Fixed on the entity and then I get an exception. It appears as if the context does not know about the previous values as the SQL statement is using the changed entities value in the WHERE clause. What is the correct approach when using ConcurrencyMode=Fixed?

  • iPhone development: Best method to allow user to chose search scope

    - by Mark Pemburn
    Hi, I'm developing my first iPhone app and want to allow the user to select the scope of their search in a more complex way than the 'scope buttons' permit. The app is related to wines and I want to the user to be able to select the 'color' (Red, White, Blush, etc.) first, and then select the type/varietal within that category. Right now, I'm using the UISearchBar's scope buttons for the colors and tapping the button opens a view with the selection of colors. This is okay except that once the 'Red' button has been selected, I can't select it a second time to change my choice of type (e.g., change from 'Merlot' to 'Syrrah', etc.) If there's a better way to do this, I'm willing to scrap my method and start from scratch. Thanks!

  • MVVM Light toolkit - maintained? Here today - gone tomorrow? ...

    - by mark smith
    Hi there, I have been taking a look at mvvm light toolkit, i must admit i haven't got a lot of experience with it but i live what i see.. I did use the mvvm toolkit (microsoft) but currently use vs 2010 and no templates are available as yet. I was looking for some insight into mvvm light toolkit... Is it always maintained ? i..e its not going to be gone tomorrow... Or shoudl i be looking elsewhere?? I would really appreciate any feedback... I also saw some info on how it is blendable which the mvvm toolkit (microsoft) didn't seem to have.. Prism also seems to be also a likely candidate but from what i understand its not a MVVM framework / toolkit i would be using it with wpf Any help really appreciated Thank you

  • Modifying CollectionEditor in PropertyGrid

    - by Chris
    I currently have a list containing Call's, which is the base class. If I want to add derived classes of Call to the list, I know to do the following. public class CustomCollectionEditor : System.ComponentModel.Design.CollectionEditor { private Type[] types; public CustomCollectionEditor(Type type) : base(type) { types = new Type[] { typeof(Call), typeof(CappedCall) }; } protected override Type[] CreateNewItemTypes() { return types; } } public class DisplayList { public DisplayList() { } [Editor(typeof(CustomCollectionEditor), typeof(UITypeEditor))] [DataMember] public List<Call> ListCalls { get; set; } } My questions is there anyway of moving where you mark up the Type[] containing all possible types the list can contain? I thought of adding the following to my CustomCollectionEditor class, but this doesn't work. public CustomCollectionEditor(Type type, List<Type> types_) : base(type) { types = types_.ToArray(); } It would be ideal if I could mark up which classes the CustomCollectionEditor needed to be aware of in the DisplayList class somehow.

  • Intellij-Idea: Marking all files of unknown type as text (so that they are searchable)

    - by sixtyfootersdude
    Many of my scripts etc in intellij are marked with a question mark. Then when I click on them them it prompts me: The file "bla" cannot be associated with a registered file type. Please choose one: <insert table of file choices> This would not matter except the files are not searchable (with ctrl-shift-n) until they are marked as text. This is a major problem for me. I have an enormous code base and I don't want to mark all of the unknown files as text. Is there anyway that I can do that?

  • mvvm-light: Should we merge Cleanup methods in locator?

    - by mark smith
    Hi there, when creating a new ViewModel within the locator class using the snippet it creates a Cleanup Method but there is already one available from the Main so hence an error.... Should we merge them all?? Or should we be renaming the method to Cleanup[Name of viewmodel] for example. I am a little confused here Another question i would like to ask is regards to the naming conventions. I tried to follow the naming convention used with "MAIN"... hence i have CreateLogin, ClearLogin, Login (non static property for binding) etc etc.. Would it not be better to use CreateLoginViewModel, ClearLoginViewModel etc?? Just curious Thanks
