Dose Django hava a function like `abort` in Flask? I want to break a request in deal with request params
I want to dealwith request parameters in Django more elegant and here is my code： With that I can use in my view function like this: def testparam(request): name = request_get(request, 'name', required=True) age = request_get(request, 'age', ptype=int, required=True) print('name: ', name) print('age: ', age) return HttpResponse('test param run') Then I ran my Django applicaiton and typed url(http://127.0.0.1:8000/test/param) in chrome but I still got the response with "test param run". I want my django to make a response when request_get function called just like abort function in flask framework. Someone can help me? -
Using Celery with a cookiecutter-django project
I'm currently building a small django project and I decided to use cookiecutter-django for a base as everything I need was included. When setting up the project I asked cookiecutter-django to include the settings for Celery and I can find everything in the project, so far so good. However I do have some issues with getting Celery to run as it should. When I start a task from from an app nothing happens. The docker containers are all started properly. Django and Postgres work, Redis is up and I was able to bash into the container and query it. From the console output I see that the celeryworker container is up and running. I also see that my tasks are being recognized by Celery: celeryworker_1 | [tasks] celeryworker_1 | . metagrabber.taskapp.celery.debug_task celeryworker_1 | . scan_and_extract_meta celeryworker_1 | . start_job After puzzling a lot about this I decided to create a new Docker container for Flower to see what's happening under the hood. Interestingly enough I can see that there is a worker and its name is correct (I compared the worker ID in the Celery container). However if I start a task from one of my views like this: celery_task_id … -
Djano /w gunicorn bottlencking with tiny cpu and memory usage
I have a django/gunicorn/nginx app on D.O. which starts throwing this error once I get up to 50 req/s. [error] 1608#1608: *584100 connect() to unix:/my/app/gunicorn.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 162.158.222.46, server: hbs.hubro.education, request: "GET /notification/count/ HTTP/1.1", upstream: "http://unix:/my/app/gunicorn.sock:/notification/count/", host: "mydomain.com" The cpu usage is really low, in the 10% area, same with memory. I've tried with gunicorn workers equaling the number of cores, twice the cores, and four times the cores, but it seems the bottleneck is somewhere else. I would be grateful for suggestions on figuring out where the bottleneck is, and if there are any recommended monitoring tools that can give me more data on the issue than the D.O dashboard, like response times, open file count, workers utilized and whatnot. -
Dynamic Model Form Fields
I have a model formset. One of the fields in the base model is a charfield. I need this field to carry different choices depending on the form. i.e. Within the formset, some forms will have choices a,b & c and others will have choice e,f and g. Despite reading Django documentation and several Q&A's in stack overflow, I'm still at a loss. The Django documentation says: Note that choices can be any iterable object – not necessarily a list or tuple. This lets you construct choices dynamically. However, it does not give an example how to do this. Would be grateful if someone could give me an example. My model: class Item(models.Model): budgetcatagory=models.ForeignKey(BudgetCatagory, on_delete=models.CASCADE) name=models.CharField(max_length=50) enName=models.CharField(max_length=30, default ="") detail=models.CharField(max_length=30) layout=models.CharField(max_length=30, default="normal") unit=models.CharField(max_length=30) unit_description=models.CharField(max_length=30, default="") unit_price=models.IntegerField(default=0) QTY=models.IntegerField(default=0) param1=models.CharField(max_length=30, blank=True) param2=models.CharField(max_length=30, blank=True) param3=models.CharField(max_length=30, blank=True) param4=models.IntegerField(default=0) parent=models.CharField(max_length=50, default = "0") cost_ave=models.IntegerField(default=0, blank=True) cost_min=models.IntegerField(default=0, blank=True) cost_max=models.IntegerField(default=0, blank=True) total_cost=models.IntegerField(default=0) objects=ItemManager() def __str__(self): return self.name Instances get constructed via the following code in an object manager: def normalCreate(self, cat, parent, name, description, unit, U, enName, Param1, Param2, Layout, min_val, max_val, ave_val): #import pdb #pdb.set_trace() if parent=="פיתוח": q=House.objects.get(user_id=U.id).plot_size else: q=House.objects.get(user_id=U.id).area I=self.create(budgetcatagory_id=cat.id, name=name, unit=unit, detail='Low', unit_description=description , parent=parent, QTY=q, unit_price=ave_val, total_cost=ave_val*q, enName=enName, cost_min=min_val, cost_max=max_val, cost_ave=ave_val ) I.save() … -

How to show PasswordResetForm errors in Django messages
I have the following view for my page to reset your password: from django.contrib.auth.forms import PasswordChangeForm def password_change(request): if request.method == 'POST': password_form = PasswordChangeForm(data=request.POST, user=request.user) if password_form.is_valid(): password_form.save() update_session_auth_hash(request, password_form.user) messages.add_message(request, messages.SUCCESS, "Password reset.") return redirect(reverse('elections:home')) else: messages.add_message(request, messages.ERROR, "Error with password reset.") return redirect('/password/new/') else: password_form = PasswordChangeForm(user=request.user) return render(request, 'registration/password_change.html', { 'form': password_form }) Some of my users are reporting that they are unable to change their password, but it is working for me. As I can't ask them what their password is for obvious reasons, I need a more informative error feedback to the user. It is my understanding that PasswordChangeForm generates errors that I can access. Is this true, and if so how do I access these errors in the view to add them to the Django message? If not, how do I create my own form that will return these errors? -

Django ORM - N rows per column. Convert SQL query to ORM query
Please convert this query - select l.id, l.product_category_id from clientapi_product l join clientapi_product r on l.product_category_id = r.product_category_id and r.id >= l.id where r.product_category_id in (1,3) group by l.id having count(*) < 5; As you can see, this query is a solution to "N rows per column value" problem, where, in this case, n = 5. So, in case you have another solution to this problem in Django ORM, that solution is also welcome. -
Django rest framework many=True serializer return unexpected result on overriding to_representation
class MyModelSerializer(serializers.Serializer): def to_representation(self, data): print(data) print(self.instance) # here data will be an object from the queryset. so this method(to_representation) will # be called as many times as number of objects in queryset (default = 10 objects) # we can get whole queryset from `self.instance` variable data_list = [{'a': 1}, {'b': 2}] # dummy data_list to check respone structure return data_list queryset = self.model.objects.all() serializer = MyModelSerializer(queryset, many=True) return Response(serializer.data) Now the problem is, serializer.data will have a a list of list and each sub list will have same data returned by to_representation method. i.e [ [{'a': 1}, {'b': 2}], [{'a': 1}, {'b': 2}], [{'a': 1}, {'b': 2}], [{'a': 1}, {'b': 2}], ... # This will be repeated number of times queryset has objects ] What is wrong with this approach. -

Django - attributes and redefined fields with a ModelForm?
I have been learning about how forms, and now ModelForms, work. In a video by Max Goodridge, he redefines a field for one of his ModelFields in his ModelForm class. That is, he manually adds a field to his ModelForm class that could have been auto-generated by the ModelForm framework. From what I have read and understood thus far, that may be something to avoid. Though, that is not where my question lies. I am wondering how redefining fields within a ModelForm class works. In the Django Docs, it is stated (with an example) that a ModelForm instance will have a form field for every model field specified. What happens then, when a form field is explicitly defined in a ModelForm instance? Are two fields generated or does ModelForm recognise that a field is already defined, thus not generating another one? Furthermore, what exactly does adding an attribute to a ModelForm instance in the views do? For example, I have seen this: form = ExampleForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.user = request.user # herein lies my confusion What exactly is happening here? I have seen people do this and adding a timestamp as well, but I fail to understand … -

Django, Redirect user to different page by user's type
I want to redirect user to different page by user's type when they login. I'm using django-allauth for login system and I created a profile table for user that has a OnetoOne field with the user table, like this.... #models.py class Profile(models.Model): TYPE_CHOICES = ( ('sup', 'supplier'), ('dis', 'distributor'), ) type = models.CharField(max_length=3, choices=TYPE_CHOICES, unique=True, null=True, blank=True, default=None) user = models.OneToOneField(User, on_delete=models.CASCADE) nationality = CountryField() company = models.CharField(max_length=50, unique=True, null=True, blank=True, default=None) phone = models.CharField(max_length=50, unique=True, null=True, blank=True, default=None) skype = models.CharField(max_length=50, unique=True, null=True, blank=True, default=None) address = models.CharField(max_length=50, unique=True, null=True, blank=True, default=None) After their login, they will access a view called "redirect". (exampale.com/app/rediect) for this view, I'm using this #views.py @login_required def redirect(request): if request.user.profile.filter(type='sup'): return redirect('/app/a') elif request.user.profile.filter(type='dis'): return redirect('app/b') However, when I access this page.

Why does Django raised IntegrityError :null value in column "user_id" violates not-null constraint when a form is committed?
I have a UserSession model that creates a session that uses the IPaddress, and city data to populate the model using Geip2.

Here is the configuration FURNITURE_SEARCH_FACETS = { 'fields': OrderedDict([ ('product_class', {'name': _('Type'), 'field': 'product_class'}), ('rating', {'name': _('Rating'), 'field': 'rating'}), ]), 'queries': OrderedDict([ ('price_range', { 'name': _('Price range'), 'field': 'price', 'queries': [ # This is a list of (name, query) tuples where the name will # be displayed on the front-end. (_('0 to 20000'), u'[0 TO 20000]'), (_('20000 to 40000'), u'[20000 TO 40000]'), (_('40000 to 60000'), u'[40000 TO 60000]'), (_('60000+'), u'[60000 TO *]'), ] }), ]), } class ProductIndex(indexes.SearchIndex, indexes.Indexable): # Search text text = indexes.CharField( document=True, use_template=True, template_name='search/indexes/product/item_text.txt') name = indexes.EdgeNgramField(model_attr='name', null=True) name_exact = indexes.CharField(model_attr='name', null=True, indexed=False) # Fields for faceting product_class = indexes.CharField(null=True, faceted=True) category = indexes.MultiValueField(null=True, faceted=True) price = indexes.FloatField(null=True, faceted=True) num_in_stock = indexes.IntegerField(null=True, faceted=True) rating = indexes.IntegerField(null=True, faceted=True) # Spelling suggestions suggestions = indexes.FacetCharField() date_created = indexes.DateTimeField(model_attr='created_at') date_updated = indexes.DateTimeField(model_attr='updated_at') _strategy = None def get_model(self): return get_model('catalogue', 'Product') def index_queryset(self, using=None): # Only index browsable products (not each individual child product) return … -
Django Sending Nav Pill Selection
I have two pills here: I just want to be able to click on them and have a variable be sent to my 'views' code to tell me which one is selected. Here is the html: <div class="col-md-2" id = "charts_tables"> <ul class="nav nav-pills nav-stacked" id = charts_tables> <li {% if type_display == 'charts' %} class="active"{% endif %}><a href="" name = "radio-option" class="text-primary" {{type_display}} == 'charts'><i class="fa fa-fw fa-bolt"></i> Charts</a></li> <li {% if type_display == 'tables' %} class="active"{% endif %}><a href="" name = "radio-option" class="text-primary" {{type_display}} == 'tables'><i class="fa fa-fw fa-calendar"></i> Tables</a></li> </ul> Ideally, when pushed I'd like to set the "type_display" variable to the name of the selected pill and pass that variable to my view file. I tried to make a similar post, but the only answer I receieved was to use radio buttons. For this project it has to be nav pills. Here's the top of my view: def analysis_view(request, action=None): print(request.GET.get("radio-option")) I've been trying to find documentation for the past two days and nothing. I don't even see a nav-pills widget type in any docs. Any help would be greatly appreciated.
