Issue with trying to upload single images across multiple different HTML form inputs in Django without Django Forms
I am trying to create digital business cards creating a custom visual editor with different html form inputs to upload different images like profile, background, logo etc., without Django Forms. I am able to get one working with the Django backend that uses to fields one for the image name and the other is image url. I was hoping to replicate this process for each image until I get to the slider section. I am still working on it so the design is not complete and using test data. I have included an image for reference of what I am trying to accomplish as silly as the test data is on there. urls.py from django.conf.urls import url from django.urls import path from . import views urlpatterns = [ url(r'^icards/icard/list/$', views.icard_list, name='icard_list'), url(r'^icards/icard/add/', views.icard_add, name='icard_add'), url(r'^icards/icard/edit/(?P<pk>\d+)/$', views.icard_edit, name='icard_edit'), # url(r'^icards/icard_details/(?P<pk>\d+)/$', views.icard_details, name='icard_details'), url(r'^icards/icard/delete/(?P<pk>\d+)/$', views.icard_delete, name='icard_delete'), # url(r'^icards/editor_base/', views.editor_base, name='editor_base'), url(r'icards/', views.icards, name='icards'), views.py def icard_edit(request, pk): print("Icard Edit Loaded") if len(Icard.objects.filter(pk=pk)) == 0: error = "Icard Not Found" return render(request, 'back/error.html', {'error': error}) icard = Icard.objects.get(pk=pk) print("Icard get function works") if request.method == 'POST': print("func: Get Data Works") name = request.POST.get('name') category = request.POST.get('category') style = request.POST.get('style') title = request.POST.get('title') logo … -
How to change the default labels of a ForeignKey field whose form's widget is a RadioSelect
In my Django app, I have this form: from django import forms from main.models import Profile class ProfileForm(forms.ModelForm): class Meta: model = Profile fields = ['picture'] widgets = { 'picture': forms.RadioSelect(), } By default, the labels of the picture field within the template are generated according to the __str__() method of the Picture model. That's because the picture field on my Profile model is actually a ForeignKey field to a Picture model. However, the value returned by that __str__() method doesn't make much sense in this particular template, and changing it is not possible because it's being used elsewhere. Therefore, is there a way I might change the default labels for the picture field of my ProfileForm? For instance, changing from the __str__()'s default picture.src + ' (' + picture.description + ')' to something like picture.description only? I have checked what the docs had to say regarding the label_from_instance, but I didn't understand how to apply it. In fact, I couldn't even understand if that would be a solution for this case. Some similiar questions here on Stack Overflow also mentioned that link of the docs, but the questions's forms were slightly different than mine, and I ended up not … -

Django-allauth Password Reset Email not sending
I have a weird problem where my allauth email will send to verify new user email address but no email will send for resetting the password. I have checked the gmail account from which the email should be sent but it only shows the verification emails as sent, its as though nothing is being done when the user clicks the reset password button on the template side. I'm not sure what I am missing..

Can't respond to AJAX call on context processor
I'm developing a website on DJANGO and I'm facing a problem: I have a button in my website that, when triggered, sends an AJAX POST request. Since this button is in multiple places of my website, i've decided to receive the AJAX request on the context processor file of my backend. This is what the request in the frontend looks like: $.ajax({ method: 'POST', headers: {'X-CSRFToken': csrftoken}, data: { "requested_item": requested_item }, dataType: "json", success: function() { // Handle success } }); And this is what the request handling looks like in the backend: requested_item = request.POST.get('requested_item') if requested_item != None: # Handle valid request return JsonResponse({'success': True}) The thing is, the return JsonResponse({'success': True}) isn't working, it throws this error: File "*path*\virtual-env\lib\site-packages\django\template\context.py", line 244, in bind_template updates.update(processor(self.request)) ValueError: dictionary update sequence element #0 has length 17; 2 is required The data arrives without any trouble from the frontend to the backend, but I can't seem to respond. I'm handling multiple AJAX requests the same way in my backend and responsing without problems, but this is the only one I handle in the context processor, so I'm sure there's something I'm missing. Thanks! -
different permissions in viewset, is it possbile?
If we have ModelViewSet, can we set different permissions per action? List for all, Create only for authenticated users, Update for Owners and Delete only for Admin? Or it's better to have some separated generics views? -
Django Unsubscribe with EmailMultiAlternatives
I'm trying to create an unsubscribe link for a newsletter and I have an email address and a unique uuid to use to identify each subscriber. My question is how can I pass the unsubscribe link to the template to be rendered without rendering the template over and over again for each subscriber. I'd like to render the template once and then send the same rendering to each subscriber, but still include the unique unsubscribe link (unsub_link below) in the template. What's the best way to do that? What I have so far is: def send_email(request): email_subs_query = Subscriptions.current.filter(sub_type="thisnewsletter").values('sub_email', 'sub_uuid') if request.method == "POST": message_html = get_template('newsletter/email-template.html') message = message_html.render( { 'email_content': email_content, 'more_content': more_content } ) for d in daily_subs_query: subscriber_email = [d.get('sub_email')] sub_id = [d.get('sub_uuid')] unsub_link = 'https://www.website.com/unsub_email/{}/{}/'.format(subscriber_email, sub_id) email = EmailMultiAlternatives( 'Today's Newsletter', 'template text', 'Newsletter Sender <admin@website.com subscriber_email, ) email.attach_alternative(message, "text/html") email.send() -
Uncaught TypeError: Cannot read properties of undefined (reading 'forEach')
I want to use Youtube API on my project where user can search for videos and it displays search results as the user is typing. I am only familiar with python and django. So, I am using a tutorial to do the JS part to add ajax. Everything in my code is exactly as shown in the tutorial but mine is not working. So my javascript for ajax is: <!-- javascript for ajax--> <script> var delayTimer; $("#div_id_search_form").keyup(function() { clearTimeout(delayTimer); $('#search_results').text('Loading...'); delayTimer = setTimeout(function() { var text = $("#div_id_search_form").val(); $.ajax({ url: '/video/search', data: { 'search_term': text }, dataType: 'json', success: function(data) { var results = ''; $('#search_results').text(''); data['items'].forEach(function(video){results += video['snippet']['title']}); $('#search_results').append(results); } }); }, 1000); }); </script> and this is my views.py file where I use my API: def video_search(request): search_form = SearchForm(request.GET) if search_form.is_valid(): encoded_search_term = urllib.parse.quote(search_form.cleaned_data['search_term']) response = requests.get(f'https://youtube.googleapis.com/youtube/v3/search?part=snippet&maxResults=6&q={ encoded_search_term }&key={ YOUTUBE_API_KEY }') return JsonResponse(response.json()) return JsonResponse({'error': 'Not able to validate form'}) My goal here is not to display youtube videos rightnow. My goal is to simply display 'Loading...' when the user is typing and if the user stops typing for one second it displays whatever the user has typed in the searchbar. So, i guess the problem is … -
Create django user with firebase User UID as id
I use django as a custom backend for firebase project. I want to create users in my django database from firebase credentials and have firebase UUID as my primary key for user in django db. So I have a model for my custom user in django: class CustomUser(AbstractUser): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) UUID from firebase seems to be a random string composed of letters and numbers, while python UUID has so many different formats, that I am confused what format should I use in my case. My goal is to create a user in django with something like that: CustomUser.objects.create( id=uuid.UUID('<<uuid from firebase>>'), username="mikhail", email="email@example.com",...) How do I do that? -

Django beginning project admin login error 2021
I have just created my first django project. I was successfully able to make templates and run the server so that I can go on my localhost and view my hello world project! However when going to localhost:8000/admin and logging in (yes I created a super user, also I am using windows 10) it brings me to a page with an error: 'RuntimeError: Model class django.contrib.sessions.models.Session doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.' It also says the same thing in my visual studio debug console. The error only comes up after running the admin page and trying to login which makes sense. I AM AWARE this question is on here from a while go and the solution of adding INSTALLED_APPS = [ ... 'django.contrib.sites', ] SITE_ID = 1 Did not work. Not sure if this is an issue with newer versions of django, but nothing online that I have checked currently has helped resolve this issue. My goal is to use the SQLite database to start actually getting my basic project going, but for the sake of consistency with other users and tutorials I would prefer if this part of the beginner programmed worked.

Django order by vote percentage

Date math with Django SQL Explorer
I have implemented Django SQL Explorer on a project and am attempting to build a query that will pull entries between today's date and 12 months prior to today's date, but I'm having a difficult time figuring out how SQL Explorer does date math. So far, about the only thing I've been able to discover is that SQL Explorer uses current_date for today's date. So: SELECT current_date; returns: 2021-10-02 I've tried using the MySQL implementation (since that's the database my project is using): SELECT current_date - INTERVAL 12 MONTH; returns: near "12": syntax error About the closest I've been able to come is some very simple math that just work on the year and strips all the rest of the date information away: SELECT current_date - 1; returns: 2020 Can anyone please help me figure out how to return the date 12 months prior to today's date in Django SQL Explorer? SELECT current_date SELECT current_date - [12 MONTH]; should return: 2021-10-02 2020-10-02 Thanks in advance! -

Best Practice to run Django/Vue application on Production
