Failed to load resources in ajax
I'm trying to access some string from django models using ajax. I'm new to ajax and i don't know where I'm going wrong. Here is Jquery code :- $(document).ready(function () { $("input.ssd").click(function () { var lsid = $(this).attr("id"); lsid = Number(lsid); $.ajax({ type: "POST", url: "/a_solution/", data: { l_sid: lsid, }, success: console.log("success") datatype: 'html', error : console.log("oops! something went wrong"), }); }); }); Here is url mapping in urls.py : url(r'^a_solution/$', views.ajax_detail, name = 'ajax_detail'), Here is views code :- def ajax_detail(request): context = {} if request.method == "POST" : l_sid = request.POST["l_sid"] else: ans = 'Oops! something went wrong' context['ans'] = ans l_sid = int(l_sid) sid = l_sid % 10 lid = l_sid // 10 solution = Solution.objects.get(id = sid) for code in solution.code_set.all : if code.language.id == lid: ans = code.source_code context['ans'] = ans break return render(request,'program/solution_detail.html',context) -
Django-q with Amazon SQS configuration
I've been trying to configure Django-q for the first time, with Amazon SQS as a broker. I'm using Python 2.7.11, Django 1.11.5, Django-q 0.9.2, boto3 1.5.28 and django-storages 1.4.1. I've been already using AWS S3 and cloudfront in my Django app for a few years, so they are configured properly. I'm using S3 and cloudfront for serving media files, while django-whitenoise for serving django static files. I've created new IAM user just for SQS and gave it AmazonSQSFullAccess. List of apps im using in my project (settings.py): INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'whitenoise.runserver_nostatic', 'django.contrib.staticfiles', 'django.contrib.sites', 'django.contrib.humanize', 'django.contrib.sitemaps', 'utils', 'storages', 'my_app', 'debug_toolbar', 'widget_tweaks', 'django_q', ) Following the Django-q documentation, i've come up to the step where i should execute this command python manage.py qcluster which gives me these errors: pickle.PicklingError: Can't pickle <class 'boto3.resources.factory.sqs.ServiceResource'> it's not found as boto3.resources.factory.sqs.ServiceResource and Django error as well: raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. which leaves me confused, i really have no idea what could be the problem.. -
Run simultaneously UWSGI and ASGI with Django
I'm currently running a Django (2.0.2) server with uWSGI having 10 workers I'm trying to implement a real time chat and I took a look at Channel. The documentation mentions that the server needs to be run with Daphne, and Daphne needs an asynchronous version of UWSGI named ASGI. I manged to install and setup ASGI and then run the server with daphne but with only one worker (a limitation of ASGI as I understood) but the load it too high for the worker. Is it possible to run the server with uWSGI with 10 workers to reply to HTTP/HTTPS requests and use ASGI/Daphne for WS/WSS (WebSocket) requests ? Or maybe it's possible to run multiples instances of ASGI ? -
How to access cleaned data in a Django form's clean() method?
I'd like to implement an input field in a Django form, phone_type, which is only required when another field, phone_number, is filled in. I'm reading the example at https://www.fusionbox.com/blog/detail/creating-conditionally-required-fields-in-django-forms/577/ on how to do this: def clean(self): shipping = self.cleaned_data.get('shipping') if shipping: msg = forms.ValidationError("This field is required.") self.add_error('shipping_destination', msg) else: # Keep the database consistent. The user may have # submitted a shipping_destination even if shipping # was not selected self.cleaned_data['shipping_destination'] = '' return self.cleaned_data where the models are defined as from django.db import models class ShippingInfo(models.Model): SHIPPING_DESTINATION_CHOICES = ( ('residential', "Residential"), ('commercial', "Commercial"), ) shipping = models.BooleanField() shipping_destination = models.CharField( max_length=15, choices=SHIPPING_DESTINATION_CHOICES, blank=True ) When comparing this code to the documentation at https://docs.djangoproject.com/en/2.0/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other, however, I notice that there is no call to super().clean(). Instead of accessing self.cleaned_data directly, should I do cleaned_data = super().clean() shipping = cleaned_data.get('shipping') in the first lines of the custom clean() method? (I would also be interested in ways to make the field conditionally visible without requiring additional jQuery/JavaScript code, e.g. using Django Crispy Forms and/or the HiddenInput widget). -
How do you get the JSON payload from django request object?
I'm making a post request that looks like so: $.post('/api/somepath/' {'containers': [{'container_type':'alert', 'id':1}....]}) And in my django views, self.request.POST shows the following: <QueryDict: {u'containers[1][container_type]': [u'alert'], u'containers[1][id]': [u'12159'], u'containers[0][id]': [u'9703'], u'containers[0][container_type]': [u'alert']}> How do I retrieve it back as a list?

Django TabularInline and formfield_for_manytomany
I try to filter results showed in a ManyToManyField, in admin. I use Django 1.11.3. I have these two models: class Data(models.Model): data_id = models.AutoField(primary_key=True) fi_id = models.IntegerField() model_name = models.CharField(max_length=255) def __str__(self): return self.model_name class Car(models.Model): fi_id = models.IntegerField() data = models.ManyToManyField(Data) def __str__(self): return str(self.fi_id) and this code in my admin.py file: admin.site.register(Data) class DataInline(admin.TabularInline): model = Car.data.through extra = 1 class CarAdmin(admin.ModelAdmin): inlines = [DataInline,] def formfield_for_manytomany(self, db_field, request, **kwargs): if db_field.name == "data": kwargs["queryset"] = Data.objects.filter(fi_id=request.GET.get('fi_id')) return super(CarAdmin, self).formfield_for_manytomany(db_field, request, **kwargs) admin.site.register(Car, CarAdmin) I added this line return db_field.formfield(**kwargs) after kwargs["queryset"], but no luck. Code works, but not for the inline section. I attached a photo. -
ModelForm __init__ being called a ridiculous amount of times
Just going to put some code and explain at the bottom. # modelforms.py # class MyModelModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop('request', None) super(MyModelModelForm, self).__init__(*args, **kwargs) print '__init__' class Meta: model = MyModel exclude = ('my_fk', ) Here I am using django-vanilla-views # views.py # class MyCreateView(NoAdminNoStaffLoginRequiredMixin, HasPermissionsMixin, CreateView): template_name = 'modelform_create.html' form_class = MyOtherModelModelForm # this modelform isn't important required_permission = 'create_model' def get_success_url(self): return reverse_lazy('mymodel_detail', kwargs={'pk': self.object.pk}) def get_context_data(self, **kwargs): context = super(MyCreateView, self).get_context_data(**kwargs) # FIXME: form's __init__ being called a lot MyModelFormset = modelformset_factory( MyModel, form=MyModelModelForm, extra=4, max_num=10, validate_max=True) if self.request.POST: formset = MyModelFormset( self.request.POST, queryset=MyModel.objects.none(), form_kwargs={'request': self.request}) else: formset = MyModelFormset( queryset=MyModel.objects.none(), form_kwargs={'request': self.request}) print formset.total_form_count() # 4, which makes sense context['formset'] = formset return context MyModelModelForm __init__ gets called 18 times. Yeah, I was wondering if I could get that from not happening. Reason being I would like it to not be called multiple times is I query the DB for forms.ChoiceField(choices=...), which queries the DB that many times unnecessarily. Or if there is a better spot for populating choices (NOTE: I cannot just do it in the same space where the field is declared.) It is a mixin that populates this certain field. … -
How to substitute a query value into a command argument

How do I get data from my AJAX Post to my Django View?
This is what My ajax call looks like $.ajax({ url:"/utility_tool/decisions/solution_options/handsontable.html", data: {csrfmiddlewaretoken: document.getElementsByName('csrfmiddlewaretoken')[0].value, getdata: JSON.stringify(hot.getData())}, dataType: 'json', type: 'POST', success: function (res) { alert(data); alert(res.status); }, error: function (res) { alert(res.status); } }); The alert for data displays correctly but alert for res.status displays "undefined".

Django pagination not working as intended, page numbers and links rendered wrong
I have four models: faculties, departments, studies and courses, all bound by a foreign key hierarchically. And I have a web page that is divided in two columns. First column contains a way to display the courses in my second column. By default, in the second column all courses are shown and by using first column filters, I can display those courses by faculty or by study programme. I set up pagination for all courses which works, but if I decide to sort courses by faculty for example, the number of the course object that gets shown, coincides with the default courses page number. And if I try to access another page number, it will redirect me to the specific page of the default courses. https://i.imgur.com/ucMgwlW.png <script> $(document).ready(function () { $('.btnClick').on('click', function () { $('.col-md-9').find('[id^="dep"]').hide(); var faculty_id = $(this).attr('id'); $('#' + faculty_id + '_tab').show().siblings('div').hide(); }); $('.btnClick2').on('click', function () { $('.col-md-9').find('[id^="std"]').hide(); var study_id = $(this).attr('id'); $('#' + study_id + '_tab').show().siblings('div').hide(); }); $('.btnClick3').on('click', function () { var a = $('.col-md-9'); a.find('[id^="fac"]').hide(); a.find('[id^="std"]').hide(); a.find('[id^="crs"]').show(); }); }); </script> <div class="row"> <div class="col-md-3"> <div class="jumbotron"> <h4>Search courses</h4> <hr> <br> <p onClick="window.location.reload()" class="btnClick3">Show all courses</p> <br> <ul> {% for faculty in faculties %} <li class="btnClick" id="fac_{{ … -
Django Filtering results inside ManyToManyField
I need to filter the results of a ManyToManyField before serializing it. Example: A user should see details on a record only if 'expiration_date' hasn't passed for 'Authorized Program' on file for the 'Individual' who is the subject of the record. My model and serializer currently show a list of ALL related Authorized Program records. Question: How can I filter that list to only non-expired records before returning as a list in the parent 'individual' record? Note: This is not a question about filtering the parent queryset based on the M2M field. It's about filtering the contents of the M2M field before returning the parent. Currently, the serializer simply skips the 'active_authorized_program_list' field. class Individual(models.Model): name = models.CharField(max_length=128, blank=True, default='') dob = models.DateField(null=True) authorized_program_list = models.ManyToManyField( 'Program', related_name='individual_authorized_program_list', through='ReleaseAuthorization', blank=True ) @property def current_age(self): if self.dob: today = datetime.date.today() return (today.year - self.dob.year) - int( (today.month, today.day) < (self.dob.month, self.dob.day)) else: return 'Unknown' @property def active_authorized_program_list(self): return ( self .authorized_program_list .get_queryset() .filter(expiration_date__lte=datetime.Date()) ) class Program(models.Model): name = models.CharField(max_length=128, blank=True, default='') individual_list = models.ManyToManyField( 'individual.Individual', related_name='program_individual_list', through='hub_program.ReleaseAuthorization', blank=True ) active = models.BooleanField(default=True) class ReleaseAuthorization(models.Model): individual = models.ForeignKey( Individual, related_name="release_authorization_individual", on_delete=models.CASCADE ) program = models.ForeignKey( Program, related_name="release_authorization_program", on_delete=models.CASCADE ) expiration_date = models.DateField() … -

Django Model Field Auto-Updates Depending on Related Instances
I am looking for a solution to being able to automatically update model instances depending on a related model instance. It seems simple and I've looked everywhere. I'm new to this so let me know I am asking the question incorrectly or thinking about it in the wrong way. I need Account.monthly_donations to automatically update to the total amount of all of it's related donations in the last 30 days. Similarly for yearly_donations and lifetime_donations. I also need Account.is_subscribed to toggle True if monthly_donations >= 20, or yearly_donations >= 200 or lifetime_donations >= 10000 and then back to False if requirements not met. class Account(models.Model): ... is_subscribed = models.BooleanField( default=False ) monthly_donations = models.PositiveIntegerField( default=0 ) yearly_donations = models.PositiveIntegerField( default=0 ) lifetime_donations = models.PositiveIntegerField( default=0 ) class Donation(models.Model): related_account = models.ForeignKey( Account, on_delete=models.CASCADE, related_name='donation' ) amount = models.IntegerField() date = models.DateField() Are signals the solution? However, I don't want the totals to update only when a new donation is saved. I need it updated daily based on the donations dates. -

Django tests - database constraint still exists even with a migration
I'm having difficulty with migrations/constraints in tests. I started with something like this: class MyModel(AbstractModelWithoutCSlug): id = models.IntegerField(primary_key=True, db_column='other_id') cslug = models.CharField(max_length=60, null=True, unique=True) This created the unique constraint on cslug without an issue. The unique=True was removed on the field (and made the migrations) to allow a command to run that would require the ability to temporarily have non-unique values. When I run the tests, I get an IntegrityError on the lack of uniqueness, even though a migration exists removing unique=True. Is it possible the migrations aren't always done in tests? I've never encountered an issue with migrations not being run before. Additionally: I'm using factory boy for the models. Could this also have an effect on it? -
Is it possible to add another class to a django-bootstrap-ui template tag
In my django project, I'm using django-bootstrap-ui 0.5.1. I have it in my settings.py INSTALLED_APPS variable, as well as installed in my virtual environment via my requirements.txt file. I've confirmed everything is working by using a basic {% container %} tag and its child tags {% row %} and {% column xs="8" sm="6" md="4" lg="3" %}, for example. My question is this: If {% container %} renders the following code: <div class='container'> </div> How can I add another class to that div, alongside 'container', so that the output looks like: <div class='container custom-class'> </div>
