Django save() method not saving to DB

How to encrypt and store data into a database using django and pycrpytodome?
I created a database using django and created a html form to store the data into the database. Now, I want to encrypt using pycryptodome and store the ciphertext into the database.

Anyone is able to delete or update other's post through url
Hy, I am developing a Django Blog application. In this application, I have a PostEdit view to edit the post, Delete post view to delete the post. These operations can only be performed by the user who has created that post. I used Delete view as a functional view and edit view as CBV. Now what is happening is that any user is able to delete or edit the others post through URL. In my delete post view since it is a functional based view, I have used if condition to prevent another user to prevent deleting someone else post. But since for post edit, I am using CBV, I am not able to find a way to prevent a user from editing someone else's post. So how can I prevent doing another user to edit someone else post? class PostUpdateView(LoginRequiredMixin ,UpdateView): model = Post template_name = 'blog/post_form.html' form_class = PostForm def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['title'] = 'Update' return context def form_valid(self, form): form.instance.author = self.request.user form.save() return super().form_valid(form) @login_required def post_delete(request, slug): post = get_object_or_404(Post, slug=slug) if (request.user == post.author): post.delete() return redirect('blog:post_list') else: return redirect('blog:post_detail', slug=slug) -
ValueError: server must be a Flask app or a boolean
I'm trying to work through the simplest dashboard example in the django-plotly-dash documentation, but I'm consistently getting the ValueError above. For the code below, assume the django project name is django_project and the django app name is dashboard. My ROOT_URLCONF at django_project/urls.py has the following relevant code: import dashboard.dash_app from dashboard.views import test_view urlpatterns = [ ... path('dashboard/', test_view, name='test_view'), path('django_plotly_dash/', include('django_plotly_dash.urls')), ] My dashboard app view, located at dashboard/views.py is as follows: from django.shortcuts import render def test_view(request): return render(request, 'dashboard/main.html') The main.html template is as follows: from django.shortcuts import render def test_view(request): return render(request, 'dashboard/main.html') {% load plotly_dash %} {% plotly_app name="SimpleExample" %} Finally, the DjangoDash app instance is created in a file called dashboard/dash_app.py. As shown earlier, this module is imported in django_project/urls.py, as above. Code is as follows: import dash import dash_core_components as dcc import dash_html_components as html from django_plotly_dash import DjangoDash app = DjangoDash('SimpleExample') app.layout = ... @app.callback(...) def callback_color(...): ... During the debugging process, the only other seemingly relevant information that I have is that the base_pathname is '/django_plotly_dash/app/SimpleExample/' Any other ideas? -
Display a fixed-length subset of a list in a Django template
I'd like to display a fixed-length subset of a set of related objects in a Django template. For example, imagine that I have a Car, which has related object Owner. I would like to display the four most recent owners, but also always display three entries even if there are fewer. So Ford Fiesta AA11 1AA 1. John Smith 2. Jane Smith 3. Jenny Smith Aston Martin DB9 1. Richard Rich 2. 3. even if the Fiesta has had 10 owners (and the DB9 has had only one). The naive way to do this would be <h1>{{car.name}}</h1> <ol> {% for owner in car.owner_set|slice:":3" %} <li>{{owner.name</li> {% endfor %} </ol> but this will only display one list item if there has only been one owner. I could also add lines like {% if car.owner_set|length < 2 %}<li></li>{% endif %} {% if car.owner_set|length < 3 %}<li></li>{% endif %} but that's terrible. Is there a nicer way to do this? -

Unable to add new model to Django Postgres DB via migration
I want to add a new model in my Django project after building my PostgresQL database. I add the model, run makemigations and migrate which both run fine. The model appears in the migrations files, but when I run python manage.py inspectdb it is not there. My initial import line works. This runs: from project import model1 When I try to load data into this model, I get the following error when I try to add this data from a CSV via get_or_create model. django.db.utils.ProgrammingError: relation "project_model1" does not exist Not sure how to fix this. Do I need to delete the database and start again. -
How to Use a DB function in a Subquery

Django- Creating a log for any changes in any model data i.e creation, updation and deletion?
So i have been given a task to create a Activity Log page which shows the changes that have happened to any model data i.e either it is created or updated or deleted. My solution is to create a Activity model and store the changes following way- 1- override the save method and delete method and then save in Activity model or 2- use signals and then save it the Activity model. the Activity model right now contains only these fields- performed_on, performed_by, type_of_operation- Creation, Updation, Deletion Is there any other better way to achieve this?? -

Django testing - monkeypatching the same method on different objects
I have two objects which call the same method. However, I would like each of them to return different data. Assuming a view which could contain something like: def my_view(request): # Somehow fetching obj1 and obj2 using the ORM # ... data1 = obj1.get_data() data2 = obj2.get_data() return render(...) Here would be the outline of a test: @patch('model.get_data') def test_returns_some_data(self, mock_get_data): mock_get_data.return_value = {'foo': 'bar'} resp = self.client.get(...) In this example, both obj1 and obj2 would return the dictionary {'foo': 'bar'}. What can I do in my test to make one of them return something else? Thanks! -
Failing at sending mail from django
I'm trying to send an "email" from a website in django. I have completed the main code for doing so: -the view function -the URLs mapping to make the function reachable from code -the sending form at a template So my sending form would trigger the view function using the path specified in the URLS.

Cannot pass User to ProfileForm when testing
I'm testing a ProfileForm that depends on a SignUp form to capture User data ( I'm showing this 2 forms in a view and it works.

Transfer a url parameter to a class based view

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. -
Using "regular" Django with Wagtail. How to use the two together?
My problem is this: I want to build a SPA blog with React. For that, I need some Django features: Djoser (for auth with jwt), some endpoints for extra actions (for example, incrementing a view in a post), add comments, read list, and stuff. I may not have searched too much, but I did not think like: - Use regular DRF views with the wagtail API - Integrate auth with JWT (or some other example like auth token, or basic auth, but using DRF) - Or else, how to do everything with Django, but include the Wagtail only to generate Blog Posts. I have seen some examples but they are far from helping me with the problem, and my time is quite short, I need to learn some things as quickly as possible to get a job (learn redux-saga, nginx, supervisor, gunicorn and finalize a book of SQL), so I decided to ask questions here. Some of my "solutions" were: - Create a separate server for posts only (i.e., to use only the wagtail) - Create a server for everything else (i.e., using Django / DRF) So on the front end I can relate everything using the ids. -
Django registration form doesn't work with custom html
The django registration form no longer works when I included my own html template. It used to work with crispy forms, but I wanted to make it custom. The problem seems to be with the validation of the form, because it doesn't get into the "if form.is_valid():" condition anymore. My HTML code is simply input fields for username, email, password and password confirmation (I only gave the code for email as an example in the code below). template: <form method="POST"> {% csrf_token %} <fieldset class="form-group"> ... <div class="form-group"> <label for="email">Email*</label> <input required pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}$" type="text" name="email" class="form-control input-email" id="email"> </div> ... </fieldset> </form> forms: class UserRegisterForm(UserCreationForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] views: def register(request): if request.method == 'POST': form = UserRegisterForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.username = form.cleaned_data['username'] post.email = form.cleaned_data['email'] ... post.save() messages.success(request, 'Account created') return redirect('home') else: form = UserRegisterForm() return render(request, 'users/register.html', {'form' : form }) -
Throw Step Specific Server Error(s) Upon Saving
I am using django form wizard to save a long and complex form. Before moving to next step, I would process the step data - save the data to server using rest api.
