Issues with value duplication in queryset filters
I am working on a web-application using django, and I would like to be able to return a queryset filter for a model that has no duplication. I know that distinct() exists but I do not know how to apply it on my code. I would like to return a list of cities from this queryset but not show duplicates. I have already tried using if statements where the for loop is for the returned queryset with no success. class StoreFilter(django_filters.FilterSet): class Meta: model = Store fields = { 'city': ['icontains'], } def my_store_filter(self, queryset, city, value): return queryset.filter(**{ city: value, }) -
How to fix "Not Found" problem for displaying images?
I'm preparing a blog component of a site, it is created inside an app of a project. It seems that there is no problem except the images are not displayed. while running, all things are OK, but just the image "alt" is displayed instead of the image. I have images without problem in other pages of this project. There is a report on Terminal: "Not Found: /article/static/images/growth_EWAl68g.png [14/Apr/2019 17:44:38] "GET /article/static/images/growth_EWAl68g.png HTTP/1.1" 404 6164" As you can see, Django uses a false address (static folder is located in root of projects) to access the images. class BlogArticle(models.Model): title = models.CharField(max_length=150) headline = models.CharField(max_length=300) body = models.TextField() post_image = models.ImageField(upload_to ="static/images") date = models.DateTimeField(auto_now_add=True) author = models.CharField(max_length=100) def __str__(self): return self.title class ArticleListView(ListView): model = BlogArticle template_name = 'article_list.html' urlpatterns = [ path('', views.HomeView, name= 'home'), path('article/', views.ArticleListView.as_view(), name='article_list'), path('article/<int:pk>/', views.ArticleDetailView.as_view(), name='article_detail'), . . .] from django.contrib import admin from django.urls import path, include from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include('allauth.urls')), path('contactus', include('sendemail.urls')), path('', include('myapp.urls')), ] if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) {% block content %} <div <div class="container mt-5 bg-light"> {% for article in object_list %} <div class="form-row"> <div class="form-group col-sm-9 "> … -

Testing Celery Beat
i work on a celery beat task within a django project which creates Database entries periodically. I know so beacuse when i set the task up like this : celery.py: from __future__ import absolute_import, unicode_literals import os from celery import Celery from celery.schedules import crontab app = Celery("clock-backend", broker=os.environ.get("RABBITMQ_URL")) app.config_from_object("django.conf:settings", namespace="CELERY") app.conf.beat_schedule = { 'create_reports_monthly': { 'task': 'project_celery.tasks.create_reports_monthly', 'schedule': 10.0, }, } app.autodiscover_tasks() And start my project it really creates an object every 10 seconds. But what i really want to do is to set it up to run every first day of a month. To do so i would change "schedule": crontab(0, 0, day_of_month="1"). Here comes my actual problem : How do i test that this really works ? And by testing i mean actual (unit)tests. What I've tried is to work with a package called freezegun. A test with this looks like this : def test_start_of_month_report_creation(self, user_object, contract_object, report_object): # set time to the last day of January with freeze_time("2019-01-31 23:59:59") as frozen_time: # let one second pass frozen_time.tick() # give the celery task some time time.sleep(20) # Test Logic to check whether the object was created # Example: assert MyModel.objects.count() > 0 But this did not work. … -

How to save the textbox fields which are dynamically created in the UI using Django?
I'm pretty new to Django. My page contains a text box named 'subtaskName'. onclicking add button, the similar textbox can be created n times with the same text filed name. On Clicking Submit button, I want to retrieve the list of textboxes values (subtaskName []) in Django from the post method. SO that I can iterate them and save them in to Database. After saving, On view page how to dynamically create n textboxes dynamically based on the total record from database. It seems like, this couldn't be done using crispy_forms. On form submit, the values for subTaskName[] are not coming Lets say three textbooks named 'subtaskName' are dynamically added. <input type="text" class="form-control" id="subtaskName"> <input type="text" class="form-control" id="subtaskName"> <input type="text" class="form-control" id="subtaskName"> ====================================================================== Actual code: HTML: <form action="SaveformsTest" method="post"> {% csrf_token %} <!--<div class="form-row"> <div class="form-group col-md-6"> <label style="font-size:40px;" for="projectTitle">Project Title</label> <input type="text" class="form-control" id="projectTitle" placeholder="Project Title"> </div> </div>--> <div class="form-group"> <div class="form-check "> <input class="form-check-input" type="checkbox" id="websiteBuild"> <label class="form-check-label" for="gridCheck"> Build </label> <div class="form-check form-check-inline"> <input class="form-check-input" type="checkbox" id="websiteUpdate"> <label class="form-check-label" for="gridCheck"> Update </label> </div> <div class="form-group"> <label style="font-size:20px;" for="task1">Website/Content</label> </div> <div class="form-row"> <div class="form-group col-md-2"> <label for="subtaskName">Name</label> <input type="text" class="form-control" id="subtaskName"> </div> <div class="form-group col-md-2"> <label for="subtaskOwner">Owner</label> <select … -
Pass query with url in Django REST Framework
I feel like this should be simple, but what I'm doing isn't paying off. In Django I have this urls.py in my app: from django.urls import path from .views import PostcodessAPIListView, PostcodesAPIID, PostcodesWithinRadius urlpatterns = [ path("<str:postcode>/<int:radius_km>", PostcodesWithinRadius.as_view(), name="results_api_radius"), path("", PostcodessAPIListView.as_view(), name="results_api_list"), path("<int:pk>", PostcodesAPIID.as_view(), name="results_api_detail"), ] And I have this view that should take a postcode and a radius in km, call an external api to convert the postcode to longitude and latitude, and then call the external api again to get postcodes within a certain radius. def get_postcodes_within_radius(self, postcode, radius_km): radius_km = 3 postcodes_within_radius = [] if radius_km <= 20: radius = radius_km * 1000 else: raise ValueError('Radius cannot be over 20km.') GET_LAT_LON_URL = f"{POSTCODE_URL}?" postcode_query = { "query": postcode } postcode_data = requests.get(GET_LAT_LON_URL, headers=None, params=postcode_query).json() print(postcode_data) querystring = { "longitude": postcode_data['result'][0]['longitude'], "latitude": postcode_data['result'][0]['latitude'], "wideSearch": radius, "limit": 100, } res = requests.get(POSTCODE_URL, headers=None, params=querystring).json() for postcode in res['result']: postcodes_within_radius.append(postcode['postcode']) return postcodes_within_radius However, the postcode and radius are not being passed through the url params - what gives? -
Django signal gets triggered before file is saved in server?
I am learning how to work with Django signals and celery tasks. So, I am uploading a bulk csv file to the server and my goal is to read the contents of the file once it is uploaded. Now, this is the approach I used, once the Fileupload object is saved, I am triggering the django post_save signal which basically does some validation and then triggers the celery task (which is where all the file read operations are done). Problem is that file is empty when it gets uploaded to the server. I noticed by commenting out the django signal bit and the file gets uploaded with the proper contents but once I activate the signal, it somehow interrupting with the file upload operation. How can i activate the django signal when the file is completely uploaded with the contents. class FileUpload(models.Model): file = models.FileField(blank=True) type = models.ForeignKey(FileType, on_delete=models.PROTECT, blank=True, null=True) category = models.ForeignKey(FileCategory, on_delete=models.PROTECT, blank=True, null=True) status = models.CharField(max_length=20, choices=STATUS_CHOICES, default=STATUS_NEW) --------- def upload_file(sender,instance,**kwargs): if kwargs['created']: process_upload_file.delay(instance.id) @app.task(ignore_result=True) def process_upload_file(file_id): try: logger.debug('Files:process_upload_file - called.') try: upload_file = FileUpload.objects.get(id=int(file_id)) except FileUpload.DoesNotExist: return None if not upload_file: logger.error('Files:process_upload_file - Could not locate upload file with ID={}'.format(file_id)) return elif not upload_file.type: logger.debug('Files:process_upload_file … -
my Form is passing a NoneType value to my model method calculation, Am I missing instancing something?
I'm trying to pass the input of a Form to my model method, to make some calculation based on my model field database values. I know I can do it with custom tag filters, but that's not effcient as I need to do complex calculation later. I've read somewhere that in Django you cannot pass paramaters to Models, but that sounds to stupid to be true... Am I missing instancing something somewhere ?? There error when I save the new value in the form is np = self.price * value unsupported operand type(s) for *: 'NoneType' and 'int'' so it is related It's also very confusing because if I set a default value inside my method, the calculation is rendering fine in the template. I would really appreciate some help Model class Product(models.Model): sku = models.CharField(max_length=30) price = models.FloatField() def __str__(self): return self.sku def multi(self, value = 2): #THIS DEFAULT '2' IS PROCESSED BY THE METHOD np = self.price * value #AND RENDERS A NP VALUE IN THE TEMPLATE return np View from .models import Product from .forms import Input def index(request): list = Product.objects.all() value = 0 #just to check if request.method == "POST": form = Input(request.POST or None) …
