m2m django implementation after following a tutorial
Scenario: I have some boxes (containers) I have some objects (samples) a sample can be split over many boxes, a box can contain many samples. I want to be able to assign a sample to a box and remove a sample from a box. I followed these tutorials 57-59, assigning friends to users, and got it working. So I now try to adapt the code, so I need to change users to boxes/containers and friends to samples. Sounds simple enough. But I'm inexperienced with the quirks of Django and where the request.user is I can't seem to get the correct syntax. So here comes the code, first the code working from the tutorial, then my attempt at refactoring it. I have 2 other tables/models Containers and Sample which the ContainerContent model fits inbetween. # models.py (tutorial) class Friend(models.Model): users = models.ManyToManyField(User) current_user = models.ForeignKey(User, related_name='owner', null=True, on_delete = models.PROTECT) # container_id = models.ForeignKey(Container, null=True, on_delete = models.PROTECT) @classmethod def make_friend(cls, current_user, new_friend): friend, created = cls.objects.get_or_create( current_user=current_user ) friend.users.add(new_friend) @classmethod def lose_friend(cls, current_user, new_friend): friend, created = cls.objects.get_or_create( current_user=current_user ) friend.users.remove(new_friend) # views.py def change_friends(request, operation, pk): friend = User.objects.get(pk=pk) if operation == 'add': Friend.make_friend(request.user, friend) elif operation == 'remove': … -
How to submit Django form using Javascript?
I have the following Django form: class EmailForm(forms.Form): name = forms.CharField(...) email = forms.CharField(...) message = forms.CharField(...) Which I then render in my HTML like so: <div class="controls"> {% csrf_token %} <div class="form-group"> {{ form.name }} </div> <div class="form-group"> {{ form.email }} </div> <div class="form-group"> {{ form.message }} </div> <input type="submit" value="Say hello" onclick="sendEmail(this);"> </div> I'm trying to disable the submit button after it's pressed. Here's my javascript function: <script> function sendEmail(this1) { var name = document.getElementById("form_name").value; var email = document.getElementById("form_email").value; var message = document.getElementById("form_message").value; var re = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/; var result = re.test(String(email).toLowerCase()); if (name != "" && result && message != "") { this1.disabled=true; } } </script> When I override the onclick field in the <input> tag, the button becomes disabled as a result of the Javascript function, but the form does not submit (the page is not reloaded, Django doesn't process the POST). How do I continue the default action for the submit button after disabling it? -

How to use jQuery .load() to get {% block content %} in django?
I'm learning web development with django. Currently I'm trying to realize a function that when I click "login" button the website will show a modal which contains the <div id="log-in">. this div is from login.html I firstly tried $('#test_modal').load('/accounts/login/ #log-in').modal('show') but it didn't work. I tried similar function to get div from pages where I didn't use {% block content %} and it works. So I'm quite confused right now.

Getting 400's from aws ELB hostcheck to work with django ALLOWED_HOSTS in aws ECS under awsvpc networking mode?
When moving over to ECS with awsvpc networking mode, my ALB says all my hosts are unhealthy because checking /status/ yields 400s. I've narrowed it down to the issue being something wrong with ALLOWED_HOSTS. How do I get my web app to give 200's to the ELB Healthchecker? -

How to Create a Webscrapper using Django and Scrapy?

Django Celery Max DB connections reached
I am running tasks on my celery worker in a django application where each task takes about 1-2 seconds to execute. Usually these executions are fine but from time to time, especially if the Django application has been deployed for a while, I start seeing errors like this: File "/usr/lib64/python3.6/site-packages/sqlalchemy/pool/base.py", line 428, in __init__ self.__connect(first_connect_check=True) File "/usr/lib64/python3.6/site-packages/sqlalchemy/pool/base.py", line 630, in __connect connection = pool._invoke_creator(self) File "/usr/lib64/python3.6/site-packages/sqlalchemy/engine/strategies.py", line 114, in connect return dialect.connect(*cargs, **cparams) File "/usr/lib64/python3.6/site-packages/sqlalchemy/engine/default.py", line 453, in connect return self.dbapi.connect(*cargs, **cparams) File "/usr/lib64/python3.6/site-packages/psycopg2/__init__.py", line 130, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) FATAL: remaining connection slots are reserved for non-replication superuser connections Which indicates to me that the Celery worker is not closing connections properly.

Django template fails to evaluate only when looking up a certain field
I am working through Section 3 of the official Django tutorial and having trouble with template variable evaluation. After adding app_name = polls to my urls.py and updating {% url 'detail' question.id %} to {% url 'polls:detail' question.id %} in my template, my template is no longer successfully evaluating one of the fields in each instance of Question. With the below code, question.question_text in polls/index.html is not being evaluated. Instead, literally {{ question.question_text }} is being displayed for each list item. However, when I change question.question_text to question.pub_date (pub_date is another field on the object), it is properly evaluated and the date is displayed. Additionally, question is evaluated to the question.question_text value I am looking for because of the Question class' __str__ method. polls/urls.py from django.urls import path from . import views app_name = 'polls' urlpatterns = [ path('', views.index, name='index'), path('<int:question_id>/', views.detail, name='detail'), path('<int:question_id>/results/', views.results, name='results'), path('<int:question_id>/vote/', views.vote, name='vote'), ] polls/views.py import datetime from django.db import models from django.utils import timezone class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) polls/index.html {% if latest_question_list %} <ul> {% for question in latest_question_list %} <li> <a href="{% url 'polls:detail' … -
Django REST Framework & Lifecycle of a Django Model instance
I have a django-rest-framework app that currently makes heavy use of computed properties in my models and my serializers. For (overly-simplified) example: models.py class Person(models.Model): first_name = models.CharField() last_name = models.CharField() @property full_name(self): return first_name + last_name serializers.py class PersonSerializer(serializers.ModelSerializer): class Meta: model = Person fields = ("first_name", "last_name", "full_name") I am interested in using Django's @cached_property instead of @property, in hopes of speeding things up, since the values being computed here shouldn't really change more than once a day. I am unsure, though, if @cached_property will actually effect how quickly DRF returns it's JSON response. The Django docs say: The @cached_property decorator caches the result of a method with a single self argument as a property. The cached result will persist as long as the instance does, so if the instance is passed around and the function subsequently invoked, the cached result will be returned. So I'm wondering what is the lifecycle of a Django model instance? Will it be created every time a call is made to a DRF view? And if so, are there alternative approaches to achieving my goal? -

Django - How to query the most recent distinct rows before an effective date?
I have a model full of effective dated rates. The notable fields on these rates are name, type, effective_date, and rate. I need to be able to filter the modifier rates to get only rates of a certain type and before a certain date. ModifierRate.objects.filter( type=settings.MODIFIER_RATE_TYPES_TAX, effective_date__lte=date) That query may return rates with the same name and type so I need them to be distinct on those two fields. .distinct('name', 'type')` However, if there is a duplicate name and type I need the most recent one. .order_by('-effective_date') After all that I need to aggregate Sum the rates on those objects. .aggregate(rate__sum=Coalesce(Sum('rate'), 0))['rate_sum'] If I try and smash all these things together I get raise NotImplementedError("aggregate() + distinct(fields) not implemented.") NotImplementedError: aggregate() + distinct(fields) not implemented. I've been googling for awhile and there are many similar questions that make use of values_list and annotate but I don't think that's what I want. How do I get the sum of the rates before a certain date that are distinct on fields name and type where the most recent distinct rate is used? Thanks. -

Merge 2 cache entries into one
There are invoices that I am caching but with 2 cache entry. First cache entry holds if caching of the invoices are existing or not. Why I am doing it? Because there is a business logic (get_cache_timeout method) that tells me when to update 2nd cache entry which is holding the actual invoice details. So, first one is a flag for me to understand if 2nd cache entry is there or not. If not, I call the backend system and update 1st and 2nd cache entry. The reason behind of having 2nd cache key with 60 days is that, for the worst case if 1st entry doesn't exist and then call to the backend system fails, I want to still return 2nd cache entry as a response instead of showing error. cache.set(f'{invoices}_cache_exists', True, get_cache_timeout()) cache.set(f'{invoices}_cache', some_cache, 60*60*24*60) Sorry for confusing explanation but I hope you get the idea behind of this solution. So, in the end my question is that for this problem how can I get rid of 1st cache entry and only having 2nd cache entry with 2 timeouts? 1st one is giving me telling when to update, and 2nd one is to remove the cache. -
