Why does my template takes forever to load when I change to the remote postgresql database?
This problem is pretty much only prevalent when I use a remote database, but select_related and prematch_related are used in query sets to fetch data, so foreign keys aren't doing it. It's faster when it's using a local sqlite database. Is there any way that i can optimize my template to load faster as there is a lot of data to be displayed there. As there are many separate pages performing the same action the backend just calls a queryset and the data is assigned to a dictionary. The template uses this to be completely dynamic. <!DOCTYPE html> {% load static %} {% load fontawesome %} {% load backend_extras %} {% load bootstrap4 %} <html> {% include "includes/header.html" %} <body style="margin: 0px; border: 0px; padding: 0px; background-color: White;"> {% include "includes/admin-nav.html" with active=name %} {% if name != 'index' %} <div id="modal-bar"> <input type="text" id="modal-search" onkeyup="searchFunc()" placeholder="Search.."> <div class="modal-btns"> <a class="modal-btn" data-modal="modal-window-add"><img src="{% static 'Cobras/imgs/add_button.png' %}"></a> </div> <div id="modal-window-add" class="modal-window modal"> <!-- Modal content --> <form action="" method="post" class="modal-content"> <div class="close">&times;</div> {% csrf_token %} {% bootstrap_form form_add %} <input type="hidden" name="method" value="add"> {% buttons %} <button type="submit" class="btn btn-primary">Submit</button> {% endbuttons %} </form> </div> </div> {% for info in data … -

Do we have a memory in Django application?
What if I want to store a short data set in the memory of my application? Do we have a memory in Django application or maybe it is better to ask if Django is alive? I know that I can save queries in Redis but I want to know if there is a better and faster way to save data in one view and retrieve those from another view using memory? Is it right or wrong at all?

How to configure the project and virtualenv paths in crontab to schedule jobs in Django?
I am using a library called django_cron to schedule tasks with Django.

Save list of records and fields into django model
I receive this list from my website admin: [['present', '2'], ['present', '3'], ['present', '4'], ['study', '1'], The first option is actually the field name that needs to be edit in Rollcall model and the second option is the user ID. Now I want to save this list to the Rollcall model: #models.py class Rollcall(models.Model): student = models.ForeignKey(User) present = models.BooleanField(default=False) study = models.BooleanField(default=False) So I first check and find the various fields that a particular user has in the list, and then I will save all those fields for one user in my model. How can I do this? -
Unable to connect two call back functions together in dash app
Hello I am working on a dash app for the first time and I am unable to fix an issue that I am facing. I have a front-end that takes the user input, does some calculation, stores the result in a hidden div and then updates the graph. The app loads fine however it runs into an error as soon as I hit the submit button. Below is the code I have written. It looks like both the callback functions triggers at the same time. app.layout = html.Div(style={'backgroundColor': colors['background']}, children=[ html.Div([ html.Div([ html.Img(src='data:image/png;base64,{}'.format(encoded_image.decode()), className="nine columns") ], className="three columns"), html.Div([ html.Div([ html.Div([ html.P("Select Month Range:"), ], className="two columns" ), html.Div([ dcc.RangeSlider( id='month_slider', # updatemode='drag', # count=1, min=1, max=maxmarks, step=1, value=[maxmarks - 1, maxmarks], marks=tags, pushable=1 ), ], className="six columns", style={}) ], className="twelve columns", style={ 'backgroundColor': '#EFEAEA', 'padding-top': '1.5em', 'padding-bottom': '1em' }), html.Div([ html.Div([ dcc.Dropdown( id='demographics', options=[ {'label': 'All 18-49', 'value': '18-49'}, {'label': 'Female 25-54', 'value': '25-54F'}, {'label': 'All 25-54', 'value': '25-54'}, ], placeholder="Select Demographics", ) ], className="two columns", style={}), html.Div([ dcc.Dropdown( id='ID', options=[ {'label': '200', 'value': 200, 'type': 'number'}, {'label': '250', 'value': 250, 'type': 'number'}, {'label': '300', 'value': 300, 'type': 'number'}, {'label': '350', 'value': 350, 'type': 'number'}, {'label': '400', 'value': 400, … -
Cors origin Policy blocked When ssl is enabled
I m trying to deploy Angular - Django project on an Azure VM it was working fine without HTTPS but I had to add FCM to the angular project which requires HTTPS since both angular and Django is running same server different ports like angular on *:80 and Django on *:8000 I had set up SSL for both separately I manage to docker it and get it up and running. But then I noticed a very strange bug on Django to enable cors headers I had to add few more options to Django Like SSL_SECURE_REDIRECT, CORS_ORIGIN_ALLOW_ALL, CORS_ORIGIN_WHITELIST. etc. And this is what happens now when I set SSL_SECURE_REDIRECT = True it works on Mozilla and safari NOT In chrome if I change that to False it works only in Chrome Mozilla and safari gives a cross-origin policy error. proxy_pass on nginx - no luck removing SSL_SECURE_REDIRECT - no luck Adding headers - no luck Added Trusted origins - no luck Re-installed CORSHEADERS plugin for Django On Local Its still working Its production so I can't force to users to use any browser Added different setting for production and local deployment - waste of time In postman It works cannot access … -
Django-vote implementation for comment up/down voting system
I am new to Django, and I am trying to implement up/downvotes in a comments app I am building, using django-vote: https://github.com/shanbay/django-vote for the implementation. However, either I am not understanding the django-vote documentation correctly or my implementation is faulty. I've looked through the source code for django-vote on its github but to no avail. I've tried tracing back the faults by having the code print to console at each step, and it seems like the django-vote app isnt actually logging the votes. If that is the case I may just try to build another one from scratch, but am not sure. HTML for the vote buttons: <i class=" vote upvote increment fas fa-chevron-circle-up" data-userid ="{{ request.user.id }}" data-commentid="{{ comment.id }}" data-action='UP' ></i> <i class="vote downvote increment fas fa-chevron-circle-down" data-userid ="{{ request.user.id }}" data-commentid="{{ comment.id }}" data-action='DOWN'></i> JS: $(".increment").click(function(event){ var v = $(this); var action = v.data('action'); var commentID = v.data('commentid'); var userID = v.data('userid'); console.log("vote submitted"); console.log(commentID); console.log(action); console.log(userID); $.ajax({ url: "/comments/vote/", data: { 'csrfmiddlewaretoken' : '{{ csrf_token }}', commentID: commentID, action: action, userID : userID, }, type: 'POST', success: function (data) { console.log(data); console.log("vote success")}, error: function() { console.log('vote failure') } }); }); Django view function: @login_required @require_POST … -

Django CreateView With ManyToManyField
I am trying to use a Django CreateView and ultimately update a ManyToMany Field if the user selects a certain value. I can get the form to validate, but ultimately it isn't updating the manytomanyfield in the database. Not sure what I'm doing wrong. I have referenced this similar SO issue, Django ManyToMany CreateView Fields In Both Tables but it was of no help to me. Thanks in advance for any thoughts. My code: class AuthorView(LoginRequiredMixin,CreateView): model = NewAuthor form_class = NewAuthorForm template_name = 'create_author.html' def form_valid(self, form): instance = form.save() if instance.status == 'Submitted': if instance.choice == "Custom": instance.access.add(instance.created_by) instance = form.save() This passes form validation, but doesn't save the created_by value in the manytomany field. I have tried to incorporate form.save(commit=False) and a subsequent form.save(), but that doesn't seem to help either. I am ultimately trying to add the created_by user to the manytomany field, but no luck so far. -
Internal Django Server Error when submitting a new object in a patch request from React form
I am using a multiselect form from react-widgets to allow users to select multiple courses and trying to add the selected courses as a patch request to Django. My multiselect is creating an array called userCourses which seems to correctly be an array of course objects that the user selected. Would it make sense to have CustomUser.courses just be an array of the course IDs since that would be easier to send as a patch?

Specifying upload_to parameter in the model does not seem to do anything
My model looks like this: class MainSample(models.Model): audio = models.FileField(upload_to='audio') In the following view, I am creating this model's instance and saving it: from .models import MainSample def index(request): MainSample.objects.all().delete() main_sample = MainSample() main_sample.audio = 'audio/main_sample.mp4' # why do I need to prepend this with 'audio'? main_sample.save() context = { 'main_sample': main_sample, } return render(request, 'mediaapp/index.html', context) And next creating an audio element in the template: <!DOCTYPE HTML> <html> <body> <audio controls src="{{main_sample.audio.url}}"</div> </body> </html> The audio file is pre-downloaded and sits in MEDIA_ROOT/audio/. The code works, but I don't understand the purpose of upload_to parameter in the model definition, even after reading about it in the Django docs. It is supposed to append audio path to my MEDIA_ROOT, yet in the view I still need to prepend the value of main_sample.audio with audio/, otherwise the template will not load the audio file. Could someone explain in plain words what does the upload_to does in this context, and if I can possibly get rid of writing audio/ again in my view? -
Preventing dangerous user input from django tinymce
Say we want to use tinymce to allow users to enter HTML formatted input. The django-tinymce package is a handy solution. But to render this later as output, we have to use {{ userinput | safe }} to display it. But do we know for a fact the original user's input is ... safe? What in particular are the kinds of malicious HTML tags we need to be wary of and sanitize? What would be a sound strategy to not strip out the legitimate tags tinymce utilizes while protecting future website users who will be presented with 'safe' user input? -
