django rest framework an always sorting field
I want to have a fixed sorting field applied to all custom sortings. To be more specific imagine we have a list of employees, if user choose this form be sorted by hire_date, I want the result be sorted by hire_date and employee_id together. I mean each ordering should be ordered by employee_id inside! For example if we have 5 employees hired today, if hire_date is the sorting field, these 5 be sorted by employee_id and for the other days the same story. using the following is not the cure. It only sorts them on employee_id when no ordering is set: queryset = models.Employee.objects.order_by('id') And this one's result is same as previous: filter_backends = (CustomFilterSetBackend, filters.OrderingFilter) custom_filters = ( ........ ) ordering_fields = (............) ordering = ('id',) tnx a million -
Django 2: TemplateDoesNotExist even if files placed properly
I have encountered interesting problem on Django 2. In my settings.py I have written this: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] After that I have created folder templates in my projects root folder. Then I have created app with name front and added it into my settings.py INSTALLED_APPS: Inside my views.py I have added this view: def index(request): return render(request, 'front/index') I have assigned its url like this: url(r'^$', views.index, name='index'), When I'm trying to access to this view I get this error: TemplateDoesNotExist at / front/index Why this happening? Did I miss something? -

Django 1.11 - xadmin app, charts widget parameters
I'm using the xadmin app, specifically trying to work with the included charts plugin. How do I start adding data from my database / models into the chart? The official xadmin documentation is incomplete. I have looked through the Django docs regarding widgets and plugins, but they weren't useful for determining how this specific implementation works. Can someone help point me in the right direction - I want to start adding parameters, so is there an explanation somewhere covering how this might be done? These are the default parameters - so it's picking up the response model belonging to my survey app, and I'd like to start populating it with data from my model / database. Example of model fields in my Survey app: class Response(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) survey = models.ForeignKey(Survey, related_name="responses") user = models.ForeignKey(User, null=True, blank=True) interview_uuid = models.CharField(_(u"Interview unique identifier"), max_length=36) class Answer(models.Model): question = models.ForeignKey(Question, related_name="answers") response = models.ForeignKey(Response, related_name="answers") created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) body = models.TextField(blank=True, null=True) @property def values(self): if len(self.body) < 3 or self.body[0:3] != "[u'": return [self.body] values = [] raw_values = self.body.split("', u'") nb_values = len(raw_values) for i, value in enumerate(raw_values): if i == 0: value … -
How to print a HttpResponse in a while loop and then append onto it for each loop?
Okay so I have this view: def fight(request): monster = Monster.objects.get(pk=request.POST['monster']) user = Profile.objects.get(pk=2) while monster.health > 0 and user.health > 0: monsterattack = random.randint(monster.minattack, monster.maxattack) userattack = random.randint(user.attack*.75, user.attack*1.5) user.health = user.health - monsterattack monster.health = monster.health - userattack HttpResponse('Player attacked for: %s\n Monster attacked for: %s\n' % (userattack, monsterattack)) return HttpResponse('You are fighting %s\n Player Health: %s \n Monsters Health: %s' % (monster.name, user.health, monster.health)) I was wondering if there was a way that i could have the first HttpResponse print to the template every time it looped and then have the second while loop print after the while loop has finished. -
Django API : Create Serializer Issue

Django Delete CBV with confirmation pop-up and multiple success url
In my case, an instance Model can be delete from: a ListView inherited View a DetailView inherited View By default, when a delete view is called: the get function calls 'confirm_delete' template. Instead I want a pop-up/modal to appear, and if delete is clicked in the modal will delete the object if the delete operation is on a ListView, after delete the user will remain on ListView and the ListView content will be updated if the delete operation is on a DetailView, after delete the user will be redirected to the ListView or another page(depending on other rules) -- So I want to know how to do Ajax calls on delete, how to have conditional success urls in delete, based of where I am before the action. -

Django Python - adding value to TimeField
I'm creating a basic model through the Django framework in Python, which demonstrates an offer on a product which will expire after 3 hours. This is my current model: class Offers(models.Model): product_id = models.CharField(max_length=10) original_price = models.CharField(max_length=5) discounted_price = models.CharField(max_length=5) offer_started = models.TimeField(auto_now_add=True, blank=True) offer_expires = ????????? (NB: The date is not important, which is why I have used a TimeField). Is there a simple way to automatically set the "offer_expires" field to 3 hours after the time in the "offer_started" field? Or if not linked to this field directly, the time that the entry is added? Many thanks! -

__get__() method without owner, instance parameters DJANGO
Quick question about something I am struggling with. Reading the Python-documentation, __get__ is defined with the necessary parameters: object.__get__(self, instance, owner) I am currently learning about writing custom middleware within Django. In the official Django documentation, an example of a middleware-class has a method: def __call__(self, request): How is this possible? How can the middleware- __call__ take request and skip instance and owner? Thank you! -
Django strange SlugField validation, error not raised before clean()
django 2.0 I have a django model, with a slug as primary key from django.core.validators import validate_slug class MyModel(models.Model): # with slug field alias = models.SlugField(max_length=200, primary_key=True, unique=True) # or charfield with slug validator (should be exactly the same) alias = models.CharField(max_length=200, primary_key=True, unique=True, validators=[validate_slug]) The problem i have, in my form i have a clean method, to validate the values of multiple fields, not individually. This method should theoretically be called after the clean_fields method, but with the SlugField, it seems the field validation is not raised before the form's clean() method. My forms.py: class MyForm(forms.ModelForm): class Meta: model = MyModel fields = '__all__' def clean(): cleaned_data = super().clean() cleaned_data['alias'] # key error with SlugField return cleaned_data To resume, with the CharField with validate_slug, everything works as intented, validation error is raised in my form, before the clean() method But with SlugField, the validation error is not raised and i got a key error because the field is missing, because not valid, even if the exception was not raised. To trigger the validation error i use accented characters, 'ééé', but allow_unicode is set to False by default. -

Advanced Django: validators within the model? UUID Field?
I'm tasked to develop a system that tracks how many times a certain task has been completed and which it was. The user who gives the tasks should be able to choose dynamically how many times that task should be completed. I think if you read the 'pseudo'-models you will understand: class Taskoverview(models.model): user = models.Foreignkey(User, related_name = 'taskoverviews') company = models.Foreignkey(Company, related_name = 'taskoverviews') limit = models.PositiveSmallIntegerField(default=5) done = models.PositiveSmallIntegerField(default=0) uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) class Task(models.model): taskoverview = models.Foreignkey(Taskoverview, related_name = 'tasks') category = models.CharField(max_length = 120) worth = models.PositiveSmallIntegerField(default=1) uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) In this example the limit declares how many tasks should be done and the done counter counts how many tasks have been done. I want to know: How can I do it, so that each 'worth' of task is allways one? Meaning that a task can't be made where worth is two? How can I ensure that a task can't be assigned to a taskoverview, if it would increase it's 'done'-counter to more that the 'limit'? How can I ensure the UUID is allways 32 digits long? Is there any method to set the first two digits of the UUID manually? Meaning can … -

call_command makemigrations does not work on EBS
I have a scenario, where I need to create a table dynamically, To create the table dynamically I have written code to create a model.py file with the table content that I want to create.

One Other thing is that as I'm creating new dynamic models So how can I push that code to the git, as on new deployment EBS will replace the existing code to new code, so in this way I will lose the files that I created in EBS using these commands Thanks -

How to perform .delete() queryset in Django in a ListView?
Here is what I've done so far: 1.) I've made a javascript function that gets all the id's of the items (using checkbox select) in the database like so (this is DataTables): function () { // count check used for checking selected items. var count = table.rows( { selected: true } ).count(); // Count check. // Count must be greater than 0 to delete an item. // if count <= 0, delete functionality won't continue. if (count > 0) { var data = table.rows( { selected: true } ).data(); var list = []; for (var i=0; i < data.length ;i++){ // alert(data[i][2]); list.push(data[i][2]); } var sData = list.join(); // alert(sData) document.getElementById('delete_items_list').value = sData; } } It outputs something like 1,2,5,7 depending on what rows I have selected. 2.) Passed the values inside a <input type="hidden">. Now, I've read a post that says you can delete data in Django database using a checkbox, but I'm not sure how exactly can I use this. I'm guessing I should put it in the ListView that I made, but how can I do that when I click the "Delete selected items" button, I can follow this answer? I'm trying to achieve what Django Admin … -

So i have following Page models and their relationships: class TeamRooster(Page): team_logo = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) @register_snippet class GroupstageTournamentModel(ClusterableModel): team_1 = models.ForeignKey( TeamRooster, null=True, verbose_name='Erste Team', on_delete=models.SET_NULL, related_name="+", ) class GroupstageScreencastRelationship(Orderable, models.Model): page = ParentalKey('ScreencastPage', related_name='groupstage_screencast_relationship') match = models.ForeignKey('GroupstageTournamentModel', related_name='match_screen_relationship') panels = [ SnippetChooserPanel('match') ] class ScreencastPage(Page): content_panels = Page.content_panels + [ InlinePanel( 'groupstage_screencast_relationship', label="Choose Teams" ] def matches(self): matches = [ n.match for n in self.groupstage_screencast_relationship.all() ] return matches def serve(self, request): if request.is_ajax(): result = [ { 'team_2_logo': match.team_2.team_logo } for match in self.matches() ] json_output = json.dumps(result) return HttpResponse(json_output) else: return super(ScreencastPage, self).serve(request) Is it possible to get a picture from the TeamRooster model with an ajax request? If I try to do this as shown in the code above, then I get an error: TypeError: Object of type 'Image' is not JSON serializable
