  • NSArrays in NSArrays. A pointer problem?

    - by RyJ
    I believe my problem involves pointers, a concept I often struggle with, but here's what I'm trying to do. I have six NSArrays. I want an additional NSArray comprised of these six arrays, so: self.arr1 = [NSArray array]; self.arr2 = [NSArray array]; self.arr3 = [NSArray array]; self.arr4 = [NSArray array]; self.arr5 = [NSArray array]; self.arr6 = [NSArray array]; NSArray *containerArray = [[NSArray alloc] initWithObjects:self.arr1, ... etc, nil]; Whenever I update one of the first 6 NSArrays, I want the object updated in containerArray. (I know I'm using an NSArray and not an NSMutableArray, when I update the arrays I create a new one and assign it to the instance variable). Currently, any manipulation of arr1 is not reflected in [containerArray objectAtIndex:0].

  • Calling a method from within a django model save() override

    - by Jonathan
    I'm overriding a django model save() method. Within the override I'm calling another method of the same class and instance which calculates one of the instance's fields based on other fields of the same instance. class MyClass(models.Model): field1 = models.FloatField() field2 = models.FloatField() field3 = models.FloatField() def calculateField1(self) self.field1 = self.field2 + self.field3 def save(self, *args, **kwargs): self.calculateField1() super(MyClass, self).save(*args, **kwargs) The override method is called when I change the model in admin. Alas I've discovered that within calculateField1() field2 and field3 have the values of the instance from before I edited them in admin. If I enter the instance again in admin and save again, only then field1 receives the correct value as field2 and field3 are already updated. Is this the correct behavior on django's side? If yes, then how can I use the new values within calculateField1? I cannot implement the calculation within the save() as calculateField1() actually quite long and I need it to be called from elsewhere.

  • Setting checkstate on a ListWidgetItem

    - by viraptor
    Hi, I'm trying to create a list of checkbox items that change the status on activation. I can connect the activate signal and everything seems to work, but changes on the screen. Am I missing some steps here? Here's the list creation: self.listField = QtGui.QListWidget(self) muted_categories = qb.settingsCollection['mutedCategories'].split('|') main_categories = sorted(set(qb.categoryTopNames.values())) for category in main_categories: item = QtGui.QListWidgetItem(category, self.listField) item.setFlags(QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsEnabled) if category in muted_categories: item.setCheckState(QtCore.Qt.Checked) else: item.setCheckState(QtCore.Qt.Unchecked) self.listField.connect(self.listField, QtCore.SIGNAL('itemActivated(QListWidgetItem*)'), self.doItemChangeState) and here's the handler: def doItemChangeState(self, item): """ invert the state of the activated item """ if item.checkState() == QtCore.Qt.Checked: item.setCheckState(QtCore.Qt.Unchecked) else: item.setCheckState(QtCore.Qt.Checked) I verified that the handler is fired after clicking - if I put prints there, it will alternate "checked" / "unchecked". What can I do to refresh the checkboxes themselves?

  • Animating removeFromSuperview

    - by brettr
    I'd like to animate the transition from a subview back to the super view. I display the subview using: [UIView beginAnimations:@"curlup" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [self.view addSubview:self.mysubview.view]; [UIView commitAnimations]; The above works fine. It's going back to the super view that I don't get any animation: [UIView beginAnimations:@"curldown" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [self.view removeFromSuperview]; [UIView commitAnimations]; Is there something different I should be doing to get the subview to animate when removed?

  • Types in Python - Google Appengine

    - by Chris M
    Getting a bit peeved now; I have a model and a class thats just storing a get request in the database; basic tracking. class SearchRec(db.Model): WebSite = db.StringProperty()#required=True WebPage = db.StringProperty() CountryNM = db.StringProperty() PrefMailing = db.BooleanProperty() DateStamp = db.DateTimeProperty(auto_now_add=True) IP = db.StringProperty() class AddSearch(webapp.RequestHandler): def get(self): searchRec = SearchRec() searchRec.WebSite = self.request.get('WEBSITE') searchRec.WebPage = self.request.get('WEBPAGE') searchRec.CountryNM = self.request.get('COUNTRY') searchRec.PrefMailing = bool(self.request.get('MAIL')) searchRec.IP = self.request.get('IP') Bool has my biscuit; I thought that setting bool(self.reque....) would set the type of the string but no matter what I pass it it still stores it as TRUE in the database. I had the same issue with using required=True on strings for the model; the damn thing kept saying that nothing was being passed... but it had. Ta

  • Beginner having a problem with classes

    - by David
    I'm working through O'Reilly's "Learning Python" and having a problem with classes. I think I understand the concept, but in practice have stumbled upon this problem. Fron page 88-89: >>> class Worker: def __innit__(self, name, pay): self.name=name self.pay=pay def lastName(self): return self.name.split()[-1] def giveRaise(self, percent): self.pay*=(1.0+percent) Then the book says "Calling the class like a function generates instances of a new type ...etc" and gives this example. bob = Worker('Bob Smith', 50000) This gives me this error: TypeError: this constructor takes no arguments. And then I start muttering profanities. So what am I doing wrong here? Thanks for the help.

  • Saving in mongoDb with Mongoose, unexpected elements saved

    - by guiomie
    When I write in my mongoDB with mongoose the operation is treated with success, my document is saved, but there is also all kind of weird other sutff written down. It seems to be mongoose code. What could cause this? I add stuff in a specific array with: resultReference.ref[arrayLocation].allEvents.push(theEvent); {id: 11, allEvents: [] } is the structure of a ref element, and I push theEvent in the allEvents array. I then resultReference.save() I use express, mongoose and mongoHQ for database. I tried on a local mongo server, and this annoyance is still there. I've print in my console the document to write before save() and non of this weird code is there. { id 11 allEvents [ 0 { _events { maxListeners 0 } _doc { _id {"$oid": "4eb87834f54944e263000003"} title "Test" allDay false start 2011-11-10 13:00:00 UTC end 2011-11-10 15:00:00 UTC url "/test/4eb87834f54944e263000002" color "#99CCFF" ref "4eb87834f54944e263000002" } _activePaths { paths { title "modify" allDay "modify" start "modify" end "modify" url "modify" color "modify" ref "modify" } states { init { } modify { title true allDay true start true end true url true color true ref true } require { } } stateNames [ 0 "require" 1 "modify" 2 "init" ] } _saveError null _validationError null isNew true _pres { save [ 0 function (next) { // we keep the error semaphore to make sure we don't // call `save` unnecessarily (we only need 1 error) var subdocs = 0 , error = false , self = this; var arrays = this._activePaths .map('init', 'modify', function (i) { return self.getValue(i); }) .filter(function (val) { return (val && val instanceof DocumentArray && val.length); }); if (!arrays.length) return next(); arrays.forEach(function (array) { subdocs += array.length; array.forEach(function (value) { if (!error) value.save(function (err) { if (!error) { if (err) { error = true; next(err); } else --subdocs || next(); } }); }); }); } 1 "function checkForExistingErrors(next) { if (self._saveError){ next(self._saveError); self._saveError = null; } else { next(); } }" 2 "function validation(next) { return self.validate.call(self, next); }" ] } _posts { save [ ] } save function () { var self = this , hookArgs // arguments eventually passed to the hook - are mutable , lastArg = arguments[arguments.length-1] , pres = this._pres[name] , posts = this._posts[name] , _total = pres.length , _current = -1 , _asyncsLeft = proto[name].numAsyncPres , _next = function () { if (arguments[0] instanceof Error) { return handleError(arguments[0]); } var _args = Array.prototype.slice.call(arguments) , currPre , preArgs; if (_args.length && !(arguments[0] === null && typeof lastArg === 'function')) hookArgs = _args; if (++_current < _total) { currPre = pres[_current] if (currPre.isAsync && currPre.length < 2) throw new Error("Your pre must have next and done arguments -- e.g., function (next, done, ...)"); if (currPre.length < 1) throw new Error("Your pre must have a next argument -- e.g., function (next, ...)"); preArgs = (currPre.isAsync ?

  • python iterators and thread-safety

    - by Igor
    I have a class which is being operated on by two functions. One function creates a list of widgets and writes it into the class: def updateWidgets(self): widgets = self.generateWidgetList() self.widgets = widgets the other function deals with the widgets in some way: def workOnWidgets(self): for widget in self.widgets: self.workOnWidget(widget) each of these functions runs in it's own thread. the question is, what happens if the updateWidgets() thread executes while the workOnWidgets() thread is running? I am assuming that the iterator created as part of the for...in loop will keep some kind of reference to the old self.widgets object? So I will finish iterating over the old list... but I'd love to know for sure.

  • Why call autorelease for iVar definition in init method?

    - by iFloh
    Hi, I just familiarise myself with the CLLocationManager and found several sample class definitions that contain the following init method: - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; } return self; } - (void)dealloc { [self.locationManager release]; [super dealloc]; } I don't understand why the iVar would be autoreleased. Does this not mean it is deallocated at the end of the init method? I am also puzzled to see the same sample codes have the iVar release in the dealloc method. Any thoughts? '

  • I get a 400 Bad Request error while using django-piston

    Hello, I am trying to use Piston to provide REST support to Django. I have implemented my handlers as per the documentation provided . The problem is that i can "read" and "delete" my resource but i cannot "create" or "update". Each time i hit the relevant api i get a 400 Bad request Error. I have extended the Resource class for csrf by using this commonly available code snippet: class CsrfExemptResource(Resource): """A Custom Resource that is csrf exempt""" def init(self, handler, authentication=None): super(CsrfExemptResource, self).init(handler, authentication) self.csrf_exempt = getattr(self.handler, 'csrf_exempt', True) My class (code snippet) looks like this: user_resource = CsrfExemptResource(User) class User(BaseHandler): allowed_methods = ('GET', 'POST', 'PUT', 'DELETE') @require_extended def create(self, request): email = request.GET['email'] password = request.GET['password'] phoneNumber = request.GET['phoneNumber'] firstName = request.GET['firstName'] lastName = request.GET['lastName'] self.createNewUser(self, email,password,phoneNumber,firstName,lastName) return rc.CREATED Please let me know how can i get the create method to work using the POST operation?

  • How to add multiple files to py2app?

    - by Niek de Klein
    I have a python script which makes a GUI. When a button 'Run' is pressed in this GUI it runs a function from an imported package (which I made) like this from predictmiP import predictor class MiPFrame(wx.Frame): [...] def runmiP(self, event): predictor.runPrediction(self.uploadProtInterestField.GetValue(), self.uploadAllProteinsField.GetValue(), self.uploadPfamTextField.GetValue(), \ self.edit_eval_all.Value, self.edit_eval_small.Value, self.saveOutputField) When I run the GUI directly from python it all works well and the program writes an output file. However, when I make it into an app, the GUI starts but when I press the button nothing happens. predictmiP does get included in build/bdist.macosx-10.3-fat/python2.7-standalone/app/collect/, like all the other imports I'm using (although it is empty, but that's the same as all the other imports I have). How can I get multiple python files, or an imported package to work with py2app?

CODE: import datetime from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __unicode__(self): return self.question def was_published_today(self): return self.pub_date.date() == datetime.date.today() class Choice(models.Model): poll = models.ForeignKey(Poll) choice = models.CharField(max_length=200) votes = models.IntegerField() def __unicode__(self): return self.question

  • (Django) Trim whitespaces from charField

    - by zardon
    How do I strip whitespaces (trim) from the end of a charField in Django? Here is my Model, as you can see I've tried putting in clean methods but these never get run. I've also tried doing name.strip(), models.charField().strip() but these do not work either. Is there a way to force the charField to trim automatically for me? Thanks. class Employee(models.Model): """(Workers, Staff, etc)""" name = models.CharField(blank=True, null=True, max_length=100) # This never gets run def clean_variable(self): data = self.cleaned_data['variable'].strip() return data def __unicode__(self): return self.name class Meta: verbose_name_plural = 'Employees' # This never gets run either class EmployeesForm(forms.ModelForm): class Meta: model = Employee def clean_description(self): #if not self.cleaned_data['description'].strip(): # raise forms.ValidationError('Your error message here') self.cleaned_data['name'].strip()

And what can be done so that proc reports Developer when Developer.lab is invoked.
