How should I store encrypted files in Django?
I have a program that encrypts user uploaded files and I want to know where is the most secure place to store the encrypted file. After the file has been uploaded I encrypt the bytes which means that I can't use the default File upload system Django uses. The options I have thought of are: As a .txt file in the server (connected to Django by using the default File upload system) Save as a text input in the database (this will be completely encrypted) Which one of these are more secure and best for use, I also would like to know if there are any more ways of storing this encrypted file. Thank you -

How can I place something at the top of a queryset in Django Rest Framework?
I have a model Post with field pinned_until = models.DateTimeField(blank=True, null=True). Let's say pinned_until has any value that is before the current time (timezone.now()), I want it to go at the top of the queryset, so it is first in the list of serialized response data. How can I accomplish that? I know it has something to do with annotate, but I haven't been able to figure it out so far. -

JavaScript setting multiple choice input field on Leaflet marker click
I have an embedded Leaflet map in a Django app with markers that are identifying different sampling locations for a study. These locations each have a unique location ID. When any of these markers are clicked, a popup appears with a form. The form has a few fields, one of them being that unique location ID for the user to select (in a multiple choice, drop-down style field). What I want to happen is when a user clicks on a marker, the location ID field in that multiple choice field in the popup is set to the unique ID of that marker. I have tried setting the field like this in a marker.on('click') function document.getElementById('location').value = marker.feature.properties.Location_Identifier ,but when you view the value after this it is still blank. I think part of the problem may be the feature.properties.Location_Identifier is the actual location ID whereas in the form Django makes the multiple choice fields be enumerated so the value there may just be an integer so there is a mismatch happening for setting the value. If anyone has any insight I would be grateful. -

Where do I store the encryption key when encrypting in Django?
I am creating a website using Django, my website will encrypt uploaded files and another user can then download the files unencrypted. It's pretty straightforward encrypting in python, but where do I store the encryption key? I encrypt the files in case the database or source code has been compromised. Then I can't store the encryption key as a file or in the database. Where can I store the encryption key? Thank you -

Django Forms translate standard error message
All my translations work except the error messages generated by forms. This is the start of my form: class MyForm(forms.Form): first_name = forms.CharField(label=_("First name"), min_length=3, required=True) Now the label "First name" translates fine to "Vorname" because I made a .po file and compiled etc.. However when entering only 2 characters the resulting error is in English and not in (this case) German, see screen print below. I have looked in Github Django repository django/conf/locale/de etc. but could not find the string "Please lengthen etc." there. So my question is: how do I get this error message to translate? I assume Django has a standard method and that this string is already in some .po file somewhere within the Django project? -
Why queryset returns value instead of instance in Django Views?

Git repository corrupted and changed files are empty after PC crash
I was working with git bash, rebasing and stashing my changes when suddenly my PC crashed. After the restart, the disk was repairing, but when it loaded the repository no longer worked, git commands returned: fatal: not a git repository (or any of the parent directories): .git All the files that I have not committed are now blank, the changes are gone. HEAD files and stash are also corrupted. I am in a panic mode. What can I do in this situation to recover lost files and restore the repository to the previous state? -
Having issues implementing Stripe in my Django Code
I am implementing a stripe charge in my django ecommerce project. So In my views, I am trying to get the data from an input element in a form, then pass into a variable in the views. Here is the Javascript that creates the input element var form = document.getElementById('stripe-form'); var hiddenInput = document.createElement('input'); hiddenInput.setAttribute('type', 'hidden'); hiddenInput.setAttribute('name', 'stripeToken'); hiddenInput.setAttribute('value', token.id); form.appendChild(hiddenInput); // Submit the form form.submit() So in the views.py, I have this: token = form.cleaned_data.get('stripeToken') save = form.cleaned_data.get('save') use_default = form.cleaned_data.get('use_default') print(form.cleaned_data) the print(form.cleaned_data) returned a dictionary {'stripetoken':'', 'save': False, 'as_default': False} stripetoken maps to the token variable, and as you can see its value is empty. The last two variables that maps to the last two keys in the dictionary returned values. The token = form.cleaned_data.get('stripeToken') is supposed to get this hiddenInput.setAttribute('value', token.id); right? When I tried getting the value of token.id, I got a response. I used Javascript alert(token.id) to do that, and I got a value displayed in my browser. So I don't know what exactly is wrong. Can someone help me out on this one? -
