How to add other url paths to django_channels app
I'm currently trying to create chat app using django channels but adding path to the urls.py is working like it does on all other apps. What i mean is when a user clicks on the link that directs them to the chat app, it doesn't send them to where i want it to, funny thing is it was working for about 2 minutes then everything changed It tried making some changes in the javascript, routing.py, consumers.py but nothing worked views.py @login_required def load_chat(request, receivers_id): requesting_users_id = request.user.id request_user = request.user receivers_user = User.objects.get(id=receivers_id) if requesting_users_id > receivers_id: chat_room_id = str(requesting_users_id) + str(receivers_id) else: chat_room_id = str(receivers_id) + str(requesting_users_id) try: Chat.objects.get(chat_id=chat_room_id) return HttpResponseRedirect(reverse('rooms', kwargs={'room_name':chat_room_id})) except Chat.DoesNotExist: combined_users = [] combined_users.append(request_user) combined_users.append(receivers_user) Chat.objects.create(chat_id=chat_room_id) get_chat = Chat.objects.get(chat_id=chat_room_id) get_chat.participants.set(combined_users) get_chat.save() print(get_chat.participants) return HttpResponseRedirect(reverse('rooms', kwargs={'room_name':chat_room_id})) @login_required def dm(request, room_name): return render(request, 'chat/room.html', { 'room_name_json': mark_safe(json.dumps(room_name)), 'username': mark_safe(json.dumps(request.user.username)) }) @login_required def room(request, room_name): return render(request, 'chat/room.html', { 'room_name_json': mark_safe(json.dumps(room_name)), 'username': mark_safe(json.dumps(request.user.username)) }) urls.py urlpatterns = [ path('', index, name='index'), path('directmessage/<int:receivers_id>/', load_chat, name='message'), path('room/<int:room_name>/', dm, name='dm'), path('<str:room_name>/', room, name='room'), ] I expect the request to go through the load_chat function first before it goes to the room directly -
How to access a model's parent fields through a foreign key
Two things that are stumping me in Django: 1. How to access parent fields within a child model that has a one-to-many parent/child relationship and 2. How do I set the default value in a CreateView form to be equal to the url parameter. For the first question, I have made child fields into foreign keys to access a parent field, but I'm assuming there is a cleaner way to do this. Code for part 2 of Question models.py class Parent(models.Model): parent_name = models.CharField(unique=True, max_length=40) parent_slug = models.SlugField(unique=True) class Child(models.Model): child_name = models.CharField(unique=True, max_length=40) child_slug models.SlugField(unique=True) parent_name = models.ForeignKey(Parent, on_delete=models.CASCADE) urls.py urlpatterns = [ ... path('<parent_slug>/children/', ChildListView.as_view(), name='child_list'), ... ] views.py class ChildCreateView(CreateView): model = Child form_class = NewBranchForm template_name = 'child_new.html' def form_valid(self, form): form.instance.parent_slug = self.kwargs['parent_slug'] return super(ChildCreateView, self).form_valid(form) forms.py class NewChildForm(forms.ModelForm): class Meta: model = Child fields = ['child_name'] -
Django: Store functions in DB
I'm developing a math app. I want to know how to implement the Problem class. I want to do something like the following: Store problems in DB: problem=Problem.objects.get(id=1) problem has two functions: problem.text and problem.answer problem.text generates the text of the problem. For example, problem.text(x,y)=str(x)+"+"+str(y)+"=?".This generates texts such as "1+2=?", "5+2=?", ... problem.answer calculates the answer of these problems. For example, problem.answer(x, y)=x+y. This is the answer to problem.text(x, y). However, models.FunctionField() does not exist in Django. Should I store problem.text and problem.answer as python codes in models.TextField and use eval()? -
Adding/changing logic in send_email method within django-registration-redux
My site runs multiple domains. Users can register on each of these domains. As a result, I need to make django-registration-redux: use the correct email address for sending registration/password reset emails use the correct email password for sending registration/password reset emails use the correct domain within registration/password reset emails I've been digging into the source code for django-registration-redux and believe that I need to update the send_email method within registration/models.py (https://github.com/macropin/django-registration/blob/master/registration/models.py) with my required changes. I'm assuming the best way to add this cusomtization is as follows: run 'pip uninstall django-registration-redux==2.2' from the source code, pull the 'registration' folder into my project go into myproject/registration/models.py and manually update the send_email method so that it includes my changes. Is there an easier or more correct way to build my custom logic into def send_email without making the changes noted above? Thanks! -
Abstract urls that are not part of your website in Django
Say for example on your django site, you have many buttons/links that redirect someone to http://stackoverflow.com. Instead of having to hardcode that in every time like <a href="http://stackoverflow.com" target="_blank" rel="noopener"> Is there a way abstract it so that you have one big list of urls, and you can just refer to with in your template with django tags? stackoverflow = "http://stackoverflow.com" <a href="{{ stackoverflow }}" target="_blank" rel="noopener"> -
MultiValueDictKeyError when attempting to retrieve ImageField
I'm trying to retrieve an ImageField from a form in a view so I can attach it to an email, however no matter which way I try to assign it, I get the following error: MultiValueDictKeyError at /url/ 'imgfile1' Request Method: GET Request URL: https://example.com/url/ Django Version: 2.2.1 Exception Type: MultiValueDictKeyError Exception Value: 'imgfile1' My view is simple enough: def form_view(request): last_name = request.POST.get('last_name', False) phone = request.POST.get('phone', False) email = request.POST.get('email', False) description = request.POST.get('description', False) form = TestForm(request.POST, request.FILES or None) imgfile1 = request.FILES['imgfile1'] if request.method == 'POST': if form.is_valid(): try: mail = EmailMessage('Test', '', ['noreply@example.com'], ['bob@example.com']) # mail.attach(imgfile1.name, imgfile1.read(), imgfile1.content_type) mail.send() template = 'email_templates/mail.html' except: return "Attachment error" form.save() template = loader.get_template('/myapps/mq_site/mq_django/main_page/templates/main_page/sent.html') return HttpResponse(template.render({}, request)) template = loader.get_template('/myapps/mq_site/mq_django/main_page/templates/main_page/form.html') return HttpResponse(template.render({'form': form}, request)) I can comment out imgfile1 = request.FILES['imgfile1'] and it will load, but this leaves me at a loss how ti access imgfile1 and attach it to my email, or at least to get it's url so I can provide a link to it. What am I doing wrong? -
Printing results of a QuerySet in template grouped by a Number
I have a model in my django app which is a list of contacts to be showed as bootstrap4 tabs as 12 results per tab in a single request without using pagination. So far I have decided to give it a try by looping through query by a division of 12 and manipulate code by using a hack from great thread here Is there a filter for divide for Django Template? and try to divide query by compute A/B: {% widthratio queryset 12 1 %} method. and printing out tab numbers by checking {{ queryset|divisibleby:"12" }} but it turns to be it only print one item from query set for each 12 pieces group. ## Tabs Header <ul id="tabs" class="nav nav-tabs" role="tablist"> <li class="nav-item"> <a id="ref-tab-1" href="#ref-pane-1" class="nav-link active" data-toggle="tab" role="tab"> 1 # Counter for 12 pieces </a> </li> </ul> ## Tabs Content <div id="content" class="tab-content" role="tablist"> <!-- Tab Page 1 --> <div id="ref-pane-1" class="card tab-pane fade show active" role="tabpanel" aria-labelledby="ref-tab-1"> <div class="card-header" role="tab" id="heading-1"> <h5> <a data-toggle="collapse" href="#collapse-1" aria-expanded="true" aria-controls="collapse-1"> # Counter for 12 pieces </a> </h5> </div> <div id="collapse-1" class="collapse show" role="tabpanel" data-parent="#content" aria-labelledby="heading-1"> <div class="card-body"> ## This is item to be looped through queryset <div class="partner"> <div … -
Django - Grouping by one column (using count)

Django - most pythonic way to add HTML to template from AJAX call
I have a web app where a user can search for a list of cameras and the search will return the cameras in an HTML table. This is the functionality I am trying to add: 1) User is brought to a barebones homepage with nothing but a search bar (think google) 2) On every keystroke the user makes in the search bar, JQuery should send an AJAX GET request to the server with the search term, and the results of the search should be shown in a table beneath the search bar. 3) If the search returns a list of cameras where they all share the same value for an attribute, a button should appear. Here is my current code. <!-- siren_search.html --> <div class="row"> <div class="col-sm-8 col-md-7 col-xl-5 mx-auto"> <form id="searchform" action="{% url 'siren_search' %}" method="GET"> <input id="searchbar" name="query" autocomplete="off" onkeyup=getCameras(this.value) placeholder="Search for the name of a jobsite." class="form-control" type="search" /> </form> </div> </div> <div class="row"> <div id="results-section" class="col-sm-8 col-md-7 col-xl-5 mx-auto"> {% if cameras.count > 0 %} <button id="trigger-all-btn" type="button" class="btn btn-lg btn-block btn-outline-danger btn-space js-trigger-all-sirens-btn">Trigger all sirens</button> <table id="camera-table" class="table table-hover"> <thead> <tr class="header"> <th scope="col" style="width:33%;">Asset Name</th> <th scope="col" style="width:33%;">Job Site</th> <th scope="col" style="width:33%;"></th> </tr> </thead> … -

Django Wagtail: Is it bad practise access data using own object.method instead of rewriting object.get_context method?
I am playing with Django Wagtail. Concerning rendering data in templates, I know that official way is rewrite get_context method in my page object. But I can just write my own method, I find it better and more clear for me. Just want to ask if this is possible way how to do that or is there any problem, catch, performance issues? Thank you very much. standard way: class Blog(Page): template = "blog/blog.html" def get_context(self, request): context = super().get_context(request) get_posts = self.get_children().live().order_by('-first_published_at').all() context['list_all'] = get_posts return context using own method: class Blog(Page): template = "blog/blog.html" def list_all(self): get_posts = self.get_children().live().order_by('-first_published_at').all() return (get_posts) Render in template - standard way: {% for post in list_all %} {{post.title}} {% endfor %} Render in template - own method: {% for post in self.list_all %} {{post.title}} {% endfor %} -
How to save fields only of the child model, and not to affect the fields of the parent model Django?
I have app 'profile' and two models: 'Human' and 'Client'. The 'Human' model extends the built-in 'User' model. And the 'Client' model expands the 'Human' model. from django.contrib.auth.models import User class Human(User): city = models.CharField(max_length=100, blank=True) address = models.CharField(max_length=150, blank=True) phone = models.CharField(max_length=30, blank=True) def __str__(self): return "{0} ({1})".format(self.username, self.get_full_name()) class Client(Human): company = models.CharField(max_length=100, blank=True) discount = models.DecimalField(max_digits=4, decimal_places=2, default=15) def __str__(self): return "#{} : {} | {} ({})".format(self.id, self.username, self.get_full_name(), self.company) In the shell, I create a new entry through the Human model: from profile.models import Human hu = Human(username='first', email='first@test.test', first_name='Mr.First', city='First City', phone="+9876543210") hu.set_password('12345678') hu.save() In the database, I see that records appear in the auth_user and profile_human tables Suppose my user has become my client. And now I need to add additional data to the Client model. This is not a new user! A record of it already exists (for example, id = 3). If I do this: from profile.models import Client cli = Client(id=3, company='FST', discount=10.00) cli.save() That, in the profile_client table an entry appears with information in the specified fields. But also, in the auth_user and profile_human tables, all information from all fields disappears. Question: How to save fields only of the child … -

Celery and Rabbit works well on Local but tasks are not received on production server
Sending email as background tasks works well on local rabbit Url, but it seems tasks are not relayed to Celery on Heroku using Rabbit:cloudAMQP Python3.6, Django2.2, Celery 4.3, Django-celery-mail 2.

Django Test Case writing for Two models relation with foreign key
I am new in Django TestCase Writing and not getting how to write TestCase for Two models. This is my Models.py from django.db import models class UserId(models.Model): userId = models.IntegerField(unique=True) class Contact(models.Model): userId = models.ForeignKey('UserId', on_delete=models.CASCADE) name = models.CharField(max_length=50) email = models.EmailField(unique=True) phone = models.IntegerField(unique=True) def __str__(self): return self.name and this is my tests.py from django.test import TestCase from ng.models import Contact class TestContactModel(TestCase): def setUp(self): self.contact = Contact(userId=25, name='jhon doe', email='testt@fk.com', phone=215448) self.contact.save() def test_contact_creation(self): self.assertEqual(Contact.objects.count(), 1) def test_contact_representation(self): self.assertEqual(self.contact.name, str(self.contact)) My Test was worked nice once there was only one models and no foreign key. Now i created two models and connect them with foreign key, that is why my TestCase not working now. Can anyone tell me how to write test for two models? or if anyone help me to write this testcase, it whould be very much appreciated -
using blocks within a loop in a Django template
use_case is a list of dictionaries that I'm passing to the template you see below. So entry is going to hold each dictionary. The values in the dictionary such as entry.picture_tagline are the correct data to put into the blocks that appear below. But apparently this is not allowed. Is there any way to use blocks like this within a loop? {% for entry in use_case %} {% block picture_tagline %} {{ entry.picture_tagline }} {% endblock %} {% block picture %} {{ entry.picture }} {% endblock %} {{ entry.picture_description }} {% block picture_description %} {% endblock %} {% endfor %} -
