SSL on Django, Nginx, and Gunicorn
I am using Nginx and gunicorn to serve my Django project. I currently have it working for ssl (https), but do not quite understand the correct settings for the settings file and nginx. Could someone have a look at my setup and tell me if anything blatantly looks wrong, or horribly executed? My Nginx File, Please Note that some lines are commented out. When I uncomment them, the site stops working. Edit: When I uncomment them all at the same time/ server { server_name example.com; listen 443 ssl; ssl on; ssl_certificate /etc/ssl/mycrt.crt; ssl_certificate_key /etc/ssl/mykey.key; location = /favicon.ico {access_log off; log_not_found off;} location /static/ { gzip on; gzip_types text/css; alias /home/project/static/; } location / { include proxy_params; # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; # proxy_set_header Host $http_host; # proxy_redirect off; proxy_pass http://unix:/home/project/myproject/project.sock; } } server { listen 80; server_name example.com www.example.com; return 301 https://example.com$request_uri; } My Gunicorn File [Unit] Description=gunicorn daemon After= network.target [Service] User=tyler Group=www-data Environment="Production=production" WorkingDirectory=/home/project/myproject ExecStart=/home/project/projectenv/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/projecty/myproject_a$ [Install] WantedBy=multi-user.target And lastly, the dajngo settings SECURE_SSL_REDIRECT = True SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True Are there any issues with this setup?

Passing Dict of Arrays using Ajax and Django
I have a dictionary of arrays that I would like to pass to my Django view. $.ajax({ url: '/fund_monitor/fund_directory', type: 'GET', data:{ filter_dict: filter_dict, }, success: function (data) { console.log(filter_dict); } }); And in my view I would like to receive this dict: if request.is_ajax(): filter_dict = request.GET.getlist('filter_dict') print("Is Ajax", filter_dict) But "Is Ajax []" gets printed out and just as an example, my filter_dict: Designated Broker:["BMO"] Fund Class:["OM"] Any ideas why a blank array gets passed? -
Django Rest Framework not hashing my password
I am trying to register a user in my Blog-API that I build using Django Rest Framework. Here is my code (serializers.py): from django.contrib.auth import get_user_model from django.contrib.auth.hashers import make_password from rest_framework.serializers import (ModelSerializer, HyperlinkedIdentityField, SerializerMethodField) User = get_user_model() class UserCreateSerializer(ModelSerializer): class Meta: model = User fields = [ 'username', 'email', 'password', ] extra_kwargs = { 'password': {'write_only': True} } def create(self, validated_data): username = validated_data['username'] email = validated_data['email'] password = validated_data['password'] user_obj = User(username=username, email=email) user_obj.set_password(password) user_obj.save() return validated_data In the Django admin the user will appear as expected. However, the password is said to be of invalid format. Can somebody point me toward a solution ? -
Temasys WebRTC for Django
Has anybody done a full fledged Django project using the WebRTC libraries of Temasys? If yes please provide a link to your GitHub Repo. I want to refer to how the JS is included in the HTML page. That is if you're okay with the sharing of the Repo. Thanks a ton. Note: Starting to scratch the surface of Django, so forgive the naivete. -

Adding HTML elements in a Django ModelForm
One of the fields in my form should display a static currency symbol as the first character in the field. This character should not be able to be deleted from the field. I understand that I can use <span> elements to insert the symbol into the field. The Problem I don't know how to put <span> tags around my form fields. Currently, this part of the site looks like the following: forms.py class JobForm(forms.ModelForm): class Meta: model = Job fields = [ 'Date', 'Time_Start', 'Time_End', 'Employee', 'Client', 'Service', 'Price', ] views.py def jobs_add(request): if request.method == "POST": form = JobForm(request.POST) if form.is_valid(): form = JobForm(request.POST) form.save() return HttpResponseRedirect(reverse('jobs')) else: form = JobForm() return render(request, 'home/jobs_edit.html', {'form': form, 'new_job': True}) page.html {% block content %} <form method="POST"> {% if new_job %} <h1>You are adding a new job</h1> {% else %} <h1>You are editing the details for job # {{ Job.Job_ID }}</h1> {% endif %} {% csrf_token %} {% form.as_ul %} <input type="submit" value="Save" /> {% if new_job %} {% else %} <input type="submit" name="delete" value="Delete" /> {% endif %} </form> {% endblock %} -

Django TestCase: recreate database in self.subTest(...)
I need to test a function with different parameters, and the most proper way for this seems to be using the with self.subTest(...) context manager. However, the function writes something to the db, and it ends up in an inconsistent state. I can delete the things I write, but it would be cleaner if I could recreate the whole db completely. Is there a way to do that? -
Django Inlineformset Only Saving the Last Row Added
I am using inlineformset to create extra rows when needed in a form. Both tables render on the same HTML page but are called from two separate html templates. The first table called new performs as I would expect it would -i.e. adds new rows, collects the data, counts the number of TOTAL_FORMS correctly in Form Data, and saves to the database. The second table renew adds new rows and collects the data but does not increment the count in TOTAL_FORMS and only saves the last row to the database. I believe I have debugged this problem to the html template files but can provide views.py and forms.py if I am wrong and is needed. I need help figuring how to get the second table renew to count the number of TOTAL_FORMS correctly and thus allowing it to be saved in the database. formset_new.html (this one works) {% for form in formset.forms %} {% if forloop.first %} <thead> <tr> {% for field in form.visible_fields %} <th>{{ field.label|capfirst }}</th> {% endfor %} </tr> </thead> {% endif %} <tr class="{% cycle 'row1' 'row2' %} formset_row {{formset_class_name}}"> {% for field in form.visible_fields %} <td> {# Include the hidden fields in the form #} … -
Django Rename dictionary value

Best way to iterate through which report groups a user belongs for security and speed
I have a model for User (Django Built-in), Reports, ReportGroups and ReportGroupMembers. A User can create a Report, that belongs to a single ReportGroup. The user can only write reports for ReportGroups they belong (hence ReportGroupMembers). In my view (below), I'd like to only show groups the user owns or is a member of and have a decorator or someway to easily prevent people from writing to groups they don't belong. ReportGroups can have a password associated (which is used to join a group). I'm not too sure the best way to design/accomplish this and have it scale well. If I didn't need it to scale I'd just for loop iterate through groups they belong. View: def dashboard(request): group_list = ReportGroup.objects.all() return render(request, 'dashboard/main.html', {'group_list': group_list}) Model: class ReportGroup(models.Model): group_name = models.CharField(max_length=64, blank=False, null=False) description = models.TextField(blank=True, null=True) avatar = models.ImageField(upload_to='profiles', null=True, blank=True) user = models.ForeignKey(User) class Meta: managed = True db_table = 'report_group' def __str__(self): return 'Group: %s - User: %s' % (self.group_name, self.user.username) class Report(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=264, unique=False) users = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) group = models.OneToOneField(ReportGroup, on_delete=models.CASCADE) class Meta: managed = True db_table = 'intelligence_report' def __str__(self): return '%s (%s)' % (self.name, self.users.username) … -
Getting django-ajax_selects to work in my search form in Django

django-leaflet installation exception
I'm new to Django and I would like to install leaflet to show the map. I've followed the installation instructions, and while the pip command seemed to work well, when I go to settings.py to add leaflet to my installed apps, when I save the file I get this error: Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x000002494D622730> At the end of the traceback there is this: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal201", "gdal20", "gdal111", "gdal110", "gdal19").

Initiate a Model based on another model's field in Django (Model inheritance)
I am trying to build an attendance management application.In this application, a user while creating an institute can choose from two attendance types : Daily or Subject wise. Based on the type chosen while creating a new institute instance I wish to initiate the corresponding Attendance model for the same. Here are the models I have planned so far: class Institute(models.Model): attendance_type = models.CharField(choices=ATTENDANCE_CHOICES) #other fields class AttedanceMixin(models.Model): institute = models.ForeignKey(Institute) #other fields class Meta: abstract = True class DailyAttendance(AttendanceMixin): #fields for dailyattendance class SubAttendance(AttendanceMixin): #fields for subject wise attendance So, for example when I choose attendance type to be Daily while creating an Institute object then all the attendance objects which are linked to that particular institute should be of DailyAttendance model and I can use the fields of DailyAttendance model. Any idea about how I can proceed further? -
hide site label from django admin
I am a beginner in django and i used sites framework to make multiple instances of a website use the same code and database but in my django admin page i noticed that it display a label site in each model to make the get or create queries based on the selected site but i want to make it use the current site to get or create objects and remove this selection from all models. how can i do this ? thanks.

Django forms.media pulling media from pip installed app
I have created a customized python app package which is a custom widget I can use in my Django Project. The custom widget is pip installed from my requirements.txt and can be found in my environment folder env/lib/python2.7/site-packages/custom_widget... Inside that there is a static folder with js and css files. The forms.Widget object itself is created with its own form assets.. see below: css = { 'all': ( 'css/datatables/dataTables.bootstrap.css', 'css/custom-widget.css', ), } js = ( 'js/plugins/datatables/jquery.dataTables.js', 'js/plugins/datatables/dataTables.bootstrap.js', 'js/custom-widget.js', ) The dataTables css and js are an older version than that of the ones in my Django Project staticfiles directory. Other locations in my Django project use newer versions of datatables. When I use the widget in an app under my project and try to include the form assets in the template with {{form.media}}, it pulls the dataTables css and js from my Django Project staticfiles directory rather than the static directory defined under my custom widget. This is a problem because they are different versions and my widget does not behave correctly. I am wondering if there is a way to pull my assets from the custom app that has been pip installed rather than from the static files defined … -
SSH and FTP showing different files
I am using a host to try and deploy my Django site but I am confused by the SSH vs. FTP. Background info: I got the IP address, name and password from my host for the VPS. I logged in using the same information via Putty and via WinSCP. Both show me as having accessed root@[VPS IP Address]. Running ls on Putty shows nothing (no files or folders). So I created a file hello.txt. WinSCP shows a lot of folders at the root, unlike Putty. I then searched all the folders for the hello.txt that I created and it's nowhere to be found. Why would accessing the same VPS via two different methods show completely different things? -
How can I get the number of content of output parsed excel?

Which field to use for storing a multiple dictionaries in Django models?
I was about to use buy_data=ArrayField(ArrayField(models.FloatField(default=0.0)),blank=False,default=[0.0,0.0]) for storing data like [123.0,321.0] for a stock where the first element in the data corresponds to the buying price and the second to the quantity of the stock bought, when I stumbled upon some articles which said that it is a bad practice. What I plan to store are multiple data entries with each one preferably like this {'buy_price': 123.0, 'quantity': 100}.Which field should be the most apt.
