Why does the Django FileInput widget never render a value? Is it a security risk?
In the source code (link) for Django Widgets it's clear that FileInput does not render a value: # django.forms.fields class FileInput(Input): input_type = 'file' needs_multipart_form = True template_name = 'django/forms/widgets/file.html' def format_value(self, value): """File input never renders a value.""" return This is different to other fields such as CharField which returns an initial string: # django.forms.fields def format_value(self, value): """ Return a value as it should appear when rendered in a template. """ if value == '' or value is None: return None if self.is_localized: return formats.localize_input(value) return str(value) Why is this? It means that if you set a default value in a FileField it is not rendered, which can be confusing for the user. Is it a security concern? The value is stil rendered if the user has previously uploaded a file (I assume via the ModelField not the FormField?), so I don't see the difference? -
Django Form.Errors message is not showing and not printing in console
I am learning django forms right now. I can not see the output of the error in the website as a text message, it only shows as a pop-up message with the default error message even though I set my own error message. Also, my console is not printing anything after if form.is_valid(): This is my views.py file: def forms(request): if request.method == 'POST': form = Forms(request.POST) if form.is_valid(): print("hello") form.save() print(form.cleaned_data) return HttpResponseRedirect('/thank_you') else: form = Forms() return render(request, "form/index.html", { 'form': form }) def thank_you(request): return render(request, 'form/thankyou.html') And here's the html file <html lang='en'> <head> <meta charset="UTF-8"> </head> <body> <form action="/thank-you" method="POST"> {% csrf_token %} {{ form.name.label_tag}} <br> {{form.name}} <br> {{form.name.errors}} <button type="submit">Send</button> </form> -
How to update data in html view in Django?
I am building a photo editor in Django. I have attached the main page code that I have so far: https://jsfiddle.net/xfnLc5to/ I want at updating the brightness scale, the effect to be visible on the photo on the left, even before pressing the submit button. How can I achieve this? So far, I managed to get the brightness value after pressing the submit button, in the views script: brightness_value = request.POST.get('brightness') original_photo = request.POST.get('originalPic') The original_photo variable is still None. How to update the brightness on the photo with the selected brightness value from the slider, before pressing the submit button? -

Can't call .delete() on a user account instance in Django

django admin renders links on readonly foreign key to which I don't have permission
I am using the latest django version (3.2.8) and I have the following problem: My user can see model "inspection" via permisson "view_inspection" My user cannot (!) see any foreign keys due to missing permissions The readonly-foreign key is still rendered as a link which leads to a 403 page What I need: Showing just the name of the object and not linking to it. Any ideas how I can fix this? Looks like a bug somehow... Googleing and browsing stack overflow didn't return any solutions. Thx in advance! -

CSRF verification failed with 403 error when deployed to AWS elastic beanstalk
After creating a Django project in local, where we tested that all the functionality was working as expected, we finally deployed it in Amazon Web Services Beanstalk. But to our dismay, the production app was showing CSRF error which was never seen during the development phase. Here is a sample of the code: models.py class CustomerAccount(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) phone_number = models.CharField(max_length=50,blank=True) first_name = models.CharField(max_length=200, null=True,blank=True) last_name = models.CharField(max_length=200, null=True,blank=True) urls.py urlpatterns = [ path('', views.index, name='customer-index'), ] views.py @login_required(login_url="/login/") def index(request): if request.method == 'POST': form = CustomerForm(request.POST) if form.is_valid(): form.save() return redirect('customers:customer-index') else: form = CustomerForm() context= { 'form': form, } return render(request, 'customers/index.html', context) index.html <div class="col-md-4"> <div class="card p-3 mb-4 mx-2"> <h3 class="text-center">New Customer</h3> <hr> <form method="POST" action="{% url 'customers:customer-index' %}"> {% csrf_token %} {{ form|crispy }} <input class="btn btn-success btn-block" type="submit" value="Add Customer"> </form> </div> </div> Additional details about our configuration: Inside the settings.py, the middleware for CSRF has been added MIDDLEWARE = [ ...

Map Flask API and Django app to same database but different tables
I have a database model which is written in Django ORM and the same database is used by Flask using SQLAlchemy for another microservice (where I need only 2/3 new and 1 exiting table) to store and query some data. So when from my Flask API, I run this command- $ flask db migrate $ flask db upgrade I can see that from migrations/versions, it is trying to delete existing tables of my Django app which I don't want to do. So my question is how to run/use Flask SQLAlchemy ORM without touching existing tables of Django app? Also From my Flask app, I want to refer to some of the existing tables of the Django app but am not sure how to do those without creating models on the Flask app because those models are already created by Django APP. N.B For a particular reason I don't want to separate the Flask API to another database -
How to display default value for models.FileField() in template CreateView?
How do I display the default value for models.FileField()? (ref) class MyModel(models.Model): myfile = models.FileField(upload_to='mydocs', default='myfile.txt') FieldField has an undocumented feature that allows a default value to be set using default=. This is a reference to an existing file, usually in the static root. The default form widget for this field is a ClearableFieldInput (ref), which uses django/forms/widgets/clearable_file_input.html as a template: {% if widget.is_initial %}{{ widget.initial_text }}: <a href="{{ widget.value.url }}">{{ widget.value }}</a> {% if not widget.required %} <input type="checkbox" name="{{ widget.checkbox_name }}" id="{{ widget.checkbox_id }}"> <label for="{{ widget.checkbox_id }}">{{ widget.clear_checkbox_label }}</label> {% endif %}<br> {{ widget.input_text }}:{% endif %} <input type="{{ widget.type }}" name="{{ widget.name }}"{% include "django/forms/widgets/attrs.html" %}> However, if default is set (initial being blank), the default value is not shown in the template, which can be confusing to the viewer. They think the field is empty, then on create() the default value is set. I am assuming that the default value is not passed to the template? If so, how can I modify the FileField to pass it? If not, how can I reference it? -
