How to run asynchronous function synchronously in python
I am learning Django and I am stuck with this problem. So basically, I have written two run functions and the second run function uses the first's output as input. Now it seems that the run function runs asynchronously so before the first run function executes completely and produces its output the second run function starts executing and since it needs the first run function output as input it does not produce any output. So, I want the run function to run synchronously. Here is the code snippet run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {video_name}_audio_stripped.mp4 -i {audio_name} -c:v copy -c:a aac {final_tutorial}"], cwd="media/") for i in range(1000000000): continue run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {final_tutorial} -vcodec libx265 -crf 28 reduce_{final_tutorial}"], cwd="media/") In the above code I have used a for loop and it works but I don't think it's the correct way. Can someone please suggest me the correct way? Here is my views.py file. def video(request): if request.method == 'POST': uploaded_video_file = request.FILES["video"] video_file_name = uploaded_video_file.name fs = FileSystemStorage() video_name = fs.save(video_file_name, uploaded_video_file) run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {video_name} -c:v copy -an {video_name}_audio_stripped.mp4"], cwd="media/") final_tutorial=video_name+"_spoken_tutorial.mp4" run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {video_name}_audio_stripped.mp4 -i {audio_name} -c:v copy -c:a aac … -

Forbidden (CSRF cookie not set.) Django
I'm trying to do an endpoint API. And for that, i'm using django. My url in urls.py is : path('tutorials/', tutorial_list_test.as_view()), and my views.py is like class tutorial_list_test(GuestOnlyView, FormView): print("test"); @api_view(['GET', 'POST', 'DELETE']) def tutorial_list(self): request = self.request; if request.method == 'POST': alldata=request.POST username = alldata.get("username", "0") print("POST name: " + username) return Response('The tutorial does not exist', status=status.HTTP_404_NOT_FOUND) But when i'm doing a request, i have everytime the same error "Forbidden (CSRF cookie not set.): /accounts/tutorials/" So I did some research, and I could see several proposed solutions. The first was to use csrf_exempt but it's not working for me: path('tutorials/', csrf_exempt(tutorial_list_test.as_view())), And it's the same for all the methods I used. Even if I remove this line from my settings.py, nothing changes # django.middleware.csrf.CsrfViewMiddleware', To test, I use Postman, but even using my angular front end, it does the same. const formData = new FormData() formData.append('username', this.username_signup); this.http.post('http://127.0.0.1:8000/accounts/tutorials/', formData) .map((data: Response) => { if (data !== null) { console.log(JSON.stringify(data)); }; }).subscribe(response => console.log(response)) I would like to know if you have any idea how I can do this. Because I need to be able to access my Models, so not using a class and directly making a def … -
How to Update Django Model Relationship only with Foreign Key Value
I'm looking for a way to update a relationship on a model in Django by only passing the foreign key value and not the model being referenced in the relationship. I understand that Django wants me to do this publisher = Publisher.objects.get(id=2) book = Book.objects.get(id=1) book.update(publisher=publisher) But I'm looking to just update the publisher using the publishers PK so something more along the lines of this. book = Book.objects.get(id=1) book.update(publisher=2) I have a significant amount of data that needs to get updated and I don't necessarily have a reference to what the model is for each field that needs to get updated on the "Book". -

Junction table referencing non existent entity

Meaning that the invoices table, there's no row, but in the junction table, there's a row that references an invoice that doesn't exist yet. Is this normal ? Because this is causing an integrity error on fixture teardown since the invoice doesn't exist and yet, there's a refrence to an invoice id in the junction table -

How to dynamically submit form input values with OnChange event using JQuery in django
I'm currently developing a simple true odd finder calculator using python, django and jquery. I need to have form input submit actions executed by jQuery as the user types in the input values. The goal is to get rid of submit buttons in the frontend html. As of nowadays calculator based web applications don't require submit buttons. The functionality behavior should look like here. I did a research and found out that i need to use JQuery. After implementing the functionality in my app, am able to type the first form input element, however upon clicking the second form input so as to start typing, my application crashes with server error 500, if i go back then type the second form input, it updates output. How can i implement form input onChange using jquery to match the referenced functionality above. My template and JQuery code {% extends "base.html" %} {% block title %}Two Way True Odd Finder{% endblock %} {% block content %} <script type="text/javascript" src = "https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.js"></script> <script type="text/javascript"> $(document).ready(function () { $('.form-control').change(function () { $('#myform').submit(); }); }); </script> <div class="container m-5"> <a href="{% url 'dashboard' %}" class="btn btn-primary">Dashboard Home</a> <a href="{% url 'index' %}" class="btn btn-primary">3 Way True … -
How to add secondary y axe in a graph object with Plotly?
I'm new with Plotly and I would like to add a secondary y axis to a Line graph in my Django view, how can I do that ? class AccountDetailView(SingleTableMixin, generic.DetailView): data_assets_hist = [] data_assets_hist.append(go.Line(x=x, y=get_test(), name='Test')) data_assets_hist.append(go.Line(x=x, y=get_bench(), name='Benchmark')) layout_weights = { 'yaxis_title': 'Title y axis', 'height': 520, 'width': 1100 } plot_div_1 = plot({'data': data_assets_hist, 'layout': layout_weights}, output_type='div',) context['plot_div_1'] = plot_div_1 return context From what I understand of the documentation the recommended way to add a secondary y axis is to call update_yaxes() but in my case it's not possible because I don't create a figure with make_subplots. I tried to insert the secondary_y parameter in several places but it throws an error. Invalid property specified for object of type plotly.graph_objs.Layout: 'secondary'
