How to make composition query based on POST data
I'm stuck, can't find a way to solve this task. I have a simple search form with 4 fields, and can't do composite query based on it. form.py class ViewerForm(forms.Form): text_search = forms.CharField(required=False) birthday_search = forms.DateField(required=False) study_from_search = forms.DateField(required=False) study_to_search = forms.DateField(required=False) I tried to do things like that, but it doesn't work properly. view.py def viewer(request): if request.method == 'POST': form = ViewerForm(request.POST) if form.is_valid: persons_list = Person.objects.all() query = [] if len(request.POST['text_search']): text = request.POST['text_search'] query.append(persons_list.filter(Q(fio__contains=text) | Q(sex__contains=text) | Q(mobile_number__contains=text) | Q(group__contains=text) | Q(edu_organization__contains=text))) if len(request.POST['text_search']): birthday = request.POST['birthday_search'] query.append(persons_list.filter(Q(birthday_date__exact=birthday))) if len(request.POST['study_from_search']): study_from_search = request.POST['study_from_search'] query.append(persons_list.filter(Q(birthday_date__exact=study_from_search))) if len(request.POST['study_to_search']): study_to_search = request.POST['study_to_search'] query.append(persons_list.filter(Q(period_of_study_to__exact=study_to_search))) persons_list.filter(query) How to make query based on POST data, if data in a filed is exist then do some filter. -
How to preserve the order in serializing JSON via MultipleChoiceField
I have a pre-defined list of valid choice: allowed_choices = ['yes', 'no', 'I don't know'] I'm working on an API using the Django rest framework. To validate and serialize the inputs I'm using the Django Fields. For this purpose I have a chosen a MulitpleChoiceField. dataColumns = serializers.MultipleChoiceField( choices=allowed_choices, allow_blank=False, source="data_columns", ) I built afterwards a pandas data frame with the inputs as columns. It is important that they are preserved in the same order. How can I validate using the MulitpleChoiceField and get returned a set with the same order as the input? -
Django celery task that will execute every day from 00:00 to 02:00
I need to set up django celery task my_task that will execute every day from 00:00 to 02:00 with 5 minutes interval in this period. It seems it is unable to set up this task in admin via django-celery-beat. How to set it properly? I need something like celery_app.conf.beat_schedule = { 'my_task_1': { 'task': 'tasks.my_task', 'schedule': crontab(minute=5), 'start': crontab(hour=0, minute=0), 'expires': crontab(hour=2, minute=0), 'args': ("94"), }, } Thank you for your time. -

Not able to verify SendGrid verification with Django
I'm currently reading a book on Django (for beginners) and I reached the point where I need to implement a password reset feature to the test website using SendGrid SMTP Relay. After creating an account and starting to create the SMTP relay I greeted with the following screen: Based on this page I added the following lines of code to my setting.py file: EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' EMAIL_HOST = 'smtp.sendgrid.net' EMAIL_HOST_USER = 'apikey' EMAIL_HOST_PASSWORD = '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' EMAIL_PORT = 587 EMAIL_USE_TLS = True After running the website and trying to reset my password (the password of the superuser) I get the desired message with the reset link in my console but sadly nothing comes to my email. Thus I get the following error message when trying to verify integration. What I tried so far: I tried creating multiple different API keys to make sure nothing was wrong with the API key I created a new SendGrid account I tried removing EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' from the settings.py file (this only made things worst) I've been trying to solve this issue for over a day now, any help would be greatly appreciated! -
How do I write this piece of code in a clean way?
I am just starting out with Django right now and I am trying to display certain div's based on a field that is picked by a user. However this code looks really sloppy and I am repeating myself.

Django template showing data of all users instead of one user
I am trying to retrieve information regarding a user's profile to display on a page. The issue is it retrieves the relevant information from every user instead of just the one logged in. I have tried requesting for only the user logged in at the time, but I unfortunately could not get it to work.

Using Django Window Functions on a Filtered QuerySet
I ran into a surprising conundrum with Window Functions no Filtered QuerySets. Consider with models: mymodel and relatedmodel where there is a one to many relationship (i.e. relatedmodel has a ForeignKey into mymodel). I was using something like this: window_lag = Window(expression=Lag("pk"), order_by=order_by) window_lead = Window(expression=Lead("pk"), order_by=order_by) window_rownnum = Window(expression=RowNumber(), order_by=order_by) qs1 = mymodel.objects.filter(relatedmodel__field=XXX) qs2 = qs1.annotate(row=window_rownnum, prior=window_lag, next=window_lead) qs3 = qs2.filter(pk=myid) which returns a lovely result in for the object pk=myid I now now it's position in the filtered list and its prior and next and I use this to great effect in browsing filtered lists. Significantly len(qs1) = len(qs2) is the size of the list and len(qs3)=1 Alas I just discovered this break badly when the filter is less specific: window_lag = Window(expression=Lag("pk"), order_by=order_by) window_lead = Window(expression=Lead("pk"), order_by=order_by) window_rownnum = Window(expression=RowNumber(), order_by=order_by) qs1 = mymodel.objects.filter(relatedmodel__field__contains=X) qs2 = qs1.annotate(row=window_rownnum, prior=window_lag, next=window_lead) qs3 = qs2.filter(pk=myid) In this instance, qs2 suddenly has more rows in it that qs1!And len(qs2)>len(qs1). Which totally breaks the browser in a sense (as prior and next are not reliable any more). The extra rows are duplicate mymodel objects, wherever more than one relatedmodel object matches the criterion. I've traced this to the generated SQL. This is … -
Is there a way to define a Django form field as integer in such way, so it takes the number from the slider in the template?

Django doesn't log to specified file from celery.py
I'm trying to figure out what to do when I want to log something outside project. I have a file celery.py in project/project/ directory. I'm trying to use logger automatic_actions which setting is specified in settings.py. Unfortunately, it doesn't log anything in it. logger = logging.getLogger('automatic_actions') @periodic_task(run_every=timedelta(seconds=5)) def export_properties(): logger.info('EXPORTING STARTED...') I suppose it is because when celery run this task, there is no Django environment setup. But when I try to setup Django: from project import settings BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.append(BASE_DIR) os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') django.setup() app = Celery('project',broker='redis://localhost') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() logger = logging.getLogger('automatic_actions') And run for example shell_plus: AttributeError: 'Settings' object has no attribute 'COMPRESS_ROOT' Do you know how to make it work? -
Use two querysets in one for loop in Django?
I'm building an inventory management app for an organisation in Django. This organisation has multiple rooms each with storage sections on shelves. I'm trying to display the number of storage spaces free in each room plus the number of occupied storage spaces using one for loop. So far, I have managed to display this data but I have to use two separate for loops and two querysets, 'Vacant_location_data' and 'Occupied_location_data'. I would like to be able to use a single for loop for this if possible as it will allow me to plot this data in a graph. Is this possible? Below is a simplified version of my code: My models.py: class Location(models.Model): loc_room = models.CharField(max_length=20, blank=True, null=True) loc_section = models.IntegerField(blank=True, null=True) loc_shelf = models.CharField(max_length=4, blank=True, null=True) My views.py: def dashboard(request): Vacant_location_data = Location.objects.values('loc_room').filter(box__isnull=True).annotate(nempty=Count('id')).order_by('loc_room') Occupied_location_data = Location.objects.values('loc_room').filter(box__isnull=False).annotate(nempty=Count('id')).order_by('loc_room') My HTML: <div class="container"> {% for each_room in Vacant_location_data %} { <p>"Room name": "Room {{each_space.loc_room}}"</p> <p>"Free Space": {{ each_room.nempty }}</p> }, {% endfor %} </div> <div class="container"> {% for each_room in Occupied_location_data %} { <p>"Room name": "Room {{each_room.loc_room}}"</p> <p>"Occupied Space": {{ each_room.nempty }}</p> }, {% endfor %} </div> -
How to fix urlpatternes does not match

Django ORM: construct query that would look for match on field in object at the last position of many to many field
I stumbled upon something I can't figure out by myself - while filtering (in Django ORM) query I would like to query for objects meeting condition, that some field of last object in the list of many to many objects is equal to some input. It may sound not so obvious, so below I provide an example: Animal model class Animal(models.Model): name = models.TextField(null=True, blank=False) awards = models.ManyToManyField(Award, related_name='awards') Award model class Award(models.Model): name = models.TextField(null=False, blank=False) place = models.TextField(null=True, blank=True) date = models.DateTimeField(null=True) Having these classes, I would like to construct query like this: Animal.objects.filter(awards__name__last='National Award') Because Animal.objects.filter(awards__name='National Award') normally returns (when using .values()) list looking like this: [{'name': u'National Award', 'place': u'capital', 'date': datetime.datetime(2018, 7, 13, 5, 2, 45, 23000), u'id': 1}, {'name': u'International Award', 'place': u'capital', 'date': datetime.datetime(2018, 10, 1, 1, 1, 55, 79000), u'id': 2}] and for such object, query would ommit it, because 'National Award' is not on the last position on the list, but if this object would have switched these entries, it would be returned by this query, since the last object name is equal to 'National Award'. I do not want to use date field for this query. -
