What does binascii.hexlify(os.urandom(32)).decode() mean?
I'm trying to develop a function which would refresh token model in django rest framework.They seem to use binascii.hexlify(os.urandom(32)).decode() for generating unique tokens for every user.How does this line ensures that token generated by it will always be unique.Suppose if i want to refresh content of token after every 10 months ,then, will binascii.hexlify(os.urandom(32)).decode() will generate unique key that has not been used by any current user or i need to check whether it is being used or not? -

Django: How to download all files as zip when button is clicked?
I've seen so many answers on how to serve zip files for download in Django but no one is explicitly telling how to call it in the client side. Maybe the answer is too obvious but I really don't get it. I have a datatable and I've included a download button in each row. When the user clicks it, all associated files will be downloaded as zip. Here's my code: In my views.py: def download_zipfile(self, request): filelist = [MyModel.path_to_file1, MyModel.path_to_file2, MyModel.path_to_file3] byte_data = BytesIO() zip_name = "%s.zip" % MyModel.id_no zip_file = zipfile.ZipFile(byte_data, 'w') for file in filelist: filename = os.path.basename(os.path.normpath(file)) zip_file.write(file, filename) zip_file.close() response = HttpResponse(byte_data.getvalue(), content_type='application/zip') response['Content-Disposition'] = 'attachment; filename=%s' %zip_name zip_file.printdir() return response In my urls.py I have: urlpatterns = [ path('download/<int:pk>', download_zipfile, name='download_zipfile'), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In my html template I have: <tr id="datarows"> <td>{{ mymodel.data1 }}</td> <td>{{ mymodel.data2 }}</td> <td>{{ mymodel.data3 }}</td> <td> <a href="{% url 'download_zipfile' mymodel.pk %}" target="_blank"> <i class="fas fa-download"></i> </a> </td> </tr> And I keep getting this error: django.urls.exceptions.NoReverseMatch: Reverse for 'download_zipfile' with arguments '('',)' not found. 1 pattern(s) tried: ['download/(?P<pk>[0-9]+)$'] I would really appreciate it if anyone would be able to help.

Retrieve query from django ORM with related fields
I created a Company in my django app, two or more person can login with the same company. I want to show the data of one user of the company to the other user of the company.

To put or not to put slash ("/") at the end of each url path
I know that using formerly url() there is a difference whether or not I put slash ("/") at the end of a sentence i.e. url(r'^fees_pricer/(?P<product>[\w-]+)/$', views.fees_pricer, name='fees_pricer'), I realized that I got the same result if I write: path('fees_pricer/<slug:prod>', views.fees_pricer, name='fees_pricer'), or path('fees_pricer/<slug:prod>/', views.fees_pricer, name='fees_pricer'), I am wondering if there is a difference or any best practice about putting shlash at the end of each path. Many thanks in advance for your answer. -
Django: How to set choices in a form to a Select widget
I am wondering if someone could help to figure out how to set initial choices to a CharField which has Select widget applied on a form level without overwriting the Meta class data(such as verbose_name coming from model level)? My form looks like that: from django.forms.widgets import Select class AssessmentFormModelForm): def __init__(self, *args, **kwargs): super(AssessmentForm, self).__init__(*args, **kwargs) # Intial choices set here (DOESN'T work) self.fields['test_taker_report_uid'].choices = [('', 'Placeholder')] class Meta: model = Assessment fields = ( 'test_taker_report_uid', ) widgets = { 'test_taker_report_uid': Select2, } I in fact know that I can make it work by removing widgets from Meta and adding it as a: class AssessmentFormModelForm): test_taker_report_uid = ChoiceField( widget=Select, choices=[('', 'Placeholder')] ) def __init__(self, *args, **kwargs): but it is annoying cause it overwrites verbose_name which i have specified on a model level, which i want to keep intact. -
django-paypal showing page not found when trying to checkout
I was able to install django-paypal and also created a sandox account, but the problem is when i try to checkout the process-payment display no page found.

Django anonymous session issue
I have this anonymous session middleware: from __future__ import unicode_literals from importlib import import_module from django.conf import settings class AnonymousSessionMiddleware(): """This middleware is used for anonymous testing, creates an anonymous session.

How to change two models using a single foreign key?
So I have a model Part which contains ConnectedTo, which is a models.ForeignKey('self'). This is supposed to function in the same way the naming suggests. If a part is connected to another part, it is listed. My problem comes when dealing with the first object created, and linking objects to parts not yet created. If I have a Part A, then it is connected to nothing because no other objects exist yet. Even though I know it is connected to B which doesn't exist yet. I can create B and refer it to the other part when I create it, but this does nothing to change the ConnectedTo value in A. I could easily write something to change both whenever something is added, but this system is designed to become quite large scale and I feel like I need a more automatic solution before it gets out of hand. -

Python - Multiple user types implementation in Dajngo 2.2
I'm working on a project using Python(3.7) and Django(2.2) in which I have to implement four types of users as (1): Personal - Below 18 (2): Personal 18 or Above (3): Coach (4): Parent, each user will share some basic fields like First & Lat name, Email, Gender, Account type but also will have different permissions, dashboards and functions and need to provide different signup forms but one login form. Along with that I also need to use the Email as the username for this project. what is a good and scalable approach? any resource or tutorial links will be appreciated. and how can I utilize django-allauth in this scenario? and here's how I was thinking to implement this: class BaseUser(AbstractBaseUser): email = models.EmailField(max_length=255, unique=True) is_personal_above_18 = models.BooleanField(default=False) is_personal_below_18 = models.BooleanField(default=False) is_parent = models.BooleanField(default=False) USERNAME_FIELD = 'email' def __str__(self): return self.email + '/s account' class PersonalAccountAbove18(BaseUser): user = models.OneToOneField(BaseUser, on_delete=models.CASCADE, primary_key=True) customer_id = models.BigIntegerField(default=generate_cid()) class PersonalAccountBelow18(BaseUser): user = models.OneToOneField(BaseUser, on_delete=models.CASCADE, primary_key=True) customer_id = models.BigIntegerField(blank=False) class ParentAccount(BaseUser): user = models.OneToOneField(BaseUser, on_delete=models.CASCADE, primary_key=True) customer_id = models.BigIntegerField(default=generate_cid()) The reason to use customer_id in each model is because later we need to connect different accounts, for example if someone wants to create an as … -

Ping from server (Ubuntu,Nginx,Gunicorn,Django)
I'm developing an app for local use and it needs to communicate with PLC and other devices in local network. Before sending data to PLC I need to know whether it is present in the network, so i tried to use ping. It all worked fine, while developing the app on Windows. Now when the app is on server I'm getting: "[Errno 1] Operation not permitted, /usr/lib/python3.6/socket.py in init, line 144", when trying to use pythonping library from my Django app. Is there some way to change permissions for the app, to make it ping.

Log into Chrome Extension without OAuth2
I'm wondering if it's possible to set up secure login authentication in a Chrome extension without OAuth2. I'm considering setting it up as follows: On opening the extension, send a POST to server which returns the CSRF token JavaScript inserts the token into the usual login form (as in Django template) [steps 1 and 2 replace the usual Django template rendering] User provides username and password and submits the form Success/Fail JSON response is returned and handled appropriately CSRF token is stored as a cookie (or in browser storage that Chrome extensions use) to enable automated login until it expires Would be great to hear possible problems/corrections to this approach as well as pointers to relevant resources! -
