How to make common authentication between 2 server - Rails & Django
the service I'm developing consists of chrome extension & web application. For it I'm trying to create 2 server: web application server (build by Rails) API server(build by Django) to receive requests from chrome extension and process user data. Those application use same database, same user information. My question is how to authenticate users -- in Rails app, users can sign-up and sign-in via form. But in API server, how to authenticate users? One solution might be JWT authentication, user get JWT token from Rails server and send token to Django server, and Django server authenticate by JWT authorization. Is that best practice -- or simply sending username & password is better then this? Thanks -
How to JSON parse using form.errors.as_json() in Django return JsonResponse(data)
In Django, I tried using form.errors.as_json() to get all form errors and here is sample json data strings. {"password2":[{"message": "This password is too short. It must contain at least 8 characters.","code":"password_too_short"}]} I wanted to loop and get all under "message" key in json so I can use it to notify the user after ajax call. Thanks -
Why does the Django django.contrib.auth.authenticate need in-place arguments?
Why does the Django authenticate function work only with this? user=authenticate( username=request.POST['username'], password=request.POST['password'] ) And not with user=authenticate( request.POST['username'], request.POST['password'] ) -
Integrate PayPal in Django app using Paypal Python SDK
I'm working on a Project in which I'm using Python(3.6) & Django(1.10) and I need to implement Paypal payment method in this project.I have decided to use the official Python SDK from Paypal instead of other third-party packages. Here's what i have tried: According to the docs as Here: Here's my Template: <form class="form"> {% csrf_token %} <div id="paypal-button"></div> <script src="https://www.paypalobjects.com/api/checkout.js"></script> <script> var CREATE_PAYMENT_URL = '{% url 'users:payment' %}'; var EXECUTE_PAYMENT_URL = 'https://my-store.com/paypal/execute-payment'; paypal.Button.render({ env: 'sandbox', // Or 'production' commit: true, // Show a 'Pay Now' button payment: function () { return paypal.request.post(CREATE_PAYMENT_URL).then(function (data) { return data.paymentID; }); }, onAuthorize: function (data) { return paypal.request.post(EXECUTE_PAYMENT_URL, { paymentID: data.paymentID, payerID: data.payerID}).then(function () { // The payment is complete! // You can now show a confirmation message to the customer }); } }, '#paypal-button'); </script> </form> From urls.py: url('^payment/$', views.PaymentProcess.as_view(), name='payment'), From views.py: class PaymentProcess(LoginRequiredMixin, generic.DetailView): def post(self, request, *args, **kwargs): mydict = { 'paymentID': 'PAYMENTID', } print('Getting payment request') return json.dumps(mydict) When Paypal submits a post request to /payment it returns 403 Forbidden error due to csrf_token, how I can pass the csrf_token with this request. Any resource or tutorial will be really appreciated. Help me, please! Thanks in advance! -
Django forms error: Select a valid choice. That choice is not one of the available choices
I am trying to create a website with two dropdown menus: Department and Course Number. The data for the dropdown menus comes from the "courses" table of my SQL database. Right now my website initializes properly and shows the correct options in the dropdown menu. However, when the user selects an option within the dropdown menu and submits their choice, Django throws a "Select a valid choice. That choice is not one of the available choices." error. I suspect that the output of my form isn't in the right format, so the selection can't be found in my database, but I've read many other SO questions with the same issue and still have gotten nowhere. Any help is appreciated. models.py from django.db import models class Dept(models.Model): dept = models.CharField(max_length=255, db_column = 'dept') class Meta: managed = False db_table = 'courses' def __str__(self): return self.dept class Course_num(models.Model): course_num = models.CharField(max_length=255, db_column = 'course_number') class Meta: managed = False db_table = 'courses' def __str__(self): return self.course_num forms.py from django import forms from .models import * class CourseForm(forms.Form): dept = forms.ModelChoiceField( queryset=Dept.objects.values_list('dept', flat = True).distinct().\ order_by('dept').exclude(dept__isnull=True), required=False, empty_label="No preference", label=u"Department") course_num = forms.ModelChoiceField( queryset=Course_num.objects.all().\ order_by('course_num').values_list('course_num', flat = True).\ distinct().exclude(course_num__isnull=True), required=False, empty_label="No preference", label=u"Course … -

Q: Django Channels on Elastic Beanstalk (aws)
I have a Django(2.0.2) app I deployed successfully to ebs. I implemented websockets with Channels(2.0.2) + Redis(4) and swapped to an Application Load Balancer following this guide: https://medium.com/@abhishek.mv1995/setting-up-django-channels-on-aws-elastic-beanstalk-716fd5a49c4a.

How to maintain form parameters when new url is called
I have a form shown in the first picture below and a set of navpills shown in the second picture. When I click the navpill it calls a url that either ends with 'charts' or 'tables'. Whenever I press the navpill though all the values in the form are cleared to the original template. I need them to stay so when I switch from charts to tables I get the same information. i.e. if there is a fund type selected I want it to still be their if I click on tables when I was previously on charts. I tried using "GET" as such: min_year = request.GET.get('year_min', None) if not min_year: min_year = '2013' But that only works if I submit the form. As soon as I click on one of the values it resets. Here is the html for the "Start Year" box: <h6>Start Year</h6> <div class="form-group"> {{form.year_min|attr:"class:form-control"}} </div> And here is the form: CHOICES = ( ('1998', '1998'), ('1999', '1999'), ('2001', '2001'), ('2002', '2002'), ('2003', '2003'), ('2004', '2004'), ('2005', '2005'), ('2006', '2006'), ('2007', '2007'), ('2008', '2008'), ('2009', '2009'), ('2010', '2010'), ('2011', '2011'), ('2012', '2012'), ('2013', '2013'), ('2014', '2014'), ('2015', '2015'), ('2016', '2016'), ('2017', '2017'), ('2018', '2018'), ) year_min … -

Django chain multiple queries in view
I have three models: Course Assignment Term A course has a ManyToManyField which accesses Django's default User in a field called student, and a ForeignKey with term An assignment has a ForeignKey with course When a user logs in to the page, I would like to show them something like this bootstrap collapse card where I can display each term and the corresponding classes with which the student is enrolled. I am able to access all of the courses in which the student is enrolled, I'm just having difficulty with figuring out the query to select the terms. I've tried using 'select_related' with no luck although I may be using it incorrectly. So far I've got course_list = Course.objects.filter(students = request.user).select_related('term'). Is there a way to acquire all of the terms and their corresponding courses so that I can display them in the way I'd like? If not, should I be modeling my database in a different way? -

HTML in django widgets?
I'm creating a project in Django. I use ModelForms quite a bit to get user data. I'd like to add help text to each of my fields. How I'd like those to appear is like this: A tiny "?" image to the right of the input, then a popup that appears when the "?" is hovered over. I have this working in CSS and HTML. What I need to do is put in an tag before every instance of help_text being displayed, along with some other HTML. From my understanding I can do this by subclassing widgets, but I've seen in several places that I shouldn't add HTML to widgets? It seems much less elegant to stop using the ModelForm auto-rendering in all my templates and instead re-write it using loops and then put the HTML in there. The help_text is never going to be controlled by anyone except me, so I don't believe XSS is a concern. Am I missing something? Is there an easier/better way to do this? Also, if someone could point me to a guide on this with an explanation, it would be much appreciated. -
Why do I get an operational error, saying a database is read-only?
I'm using SQLite with Django, have been for a few months. Today I was about to do replace a table with an updated version, which I regarded as tricky so I took a full backup of my entire project. At a certain point, I started getting this error -- with subtext "attempt to write a readonly database." This made no sense to me, but after trying and failing to fix it, I renamed the entire directory and restored the morning backup. No help. I tried a different browser. No help. I logged in with an incognito session. No help. I logged in with an incognito session and a different Django user account. No help. In all cases, it's the login that fails. And it fails just after I enter the password. The site is still in debug mode, and I've pasted the error info to http://dpaste.com/2NS9ZMJ.txt I have no idea how to get my site working again, if a complete restore of the project directory won't do it. -
Modifying a field in serializers.ModelSerializer Class imported from an external library
I'm trying to override/modify a class XXXSerializer(serializers.ModelSerializer) object defined in an external library that I am including in the installed_apps configuration of my settings.py. class XXXSerializer(serializers.ModelSerializer): username = serializers.CharField(validators=[UniqueValidator(queryset=User.objects.all())]) email = serializers.CharField(validators=[UniqueValidator(queryset=User.objects.all())],default='') class Meta: model = User exclude = [ 'is_superuser', 'is_staff', 'is_active', 'content_type', 'groups', 'user_permissions', 'account_id', ] As shown above, the email is required to be unique in their definition. However, I do not want to require it to be unique. My question is therefore, what is the best way to override this field? Some thoughts/attempts: Copy the entire library directly into my project, and take out the validator there. I think this would definitely work but may not be an optimal solution? Somehow override it by defining another YYYSerializer with my desired property, and use import external_library sys.module['external_library.XXXSerializer'] = YYYSerializer. However, I'm not exactly sure about 1. where to put this piece of code, 2. the proper syntax, 3. whether this would even work in an ideal situation. When I put it in settings.py or some __init__ files, it returns Apps aren't loaded yet error - probably because the external_library hasn't been loaded yet. Any suggestions would be appreciated! -

django import csv in several related models
For a web application of naturalistic data for the study of bats (http://www.dbchiro.org), I need to be able to propose a view allowing to import files from spreadsheets (csv, ods files , xls) into database. To import this data into a single table, no problem, several extensions exist (django-import-export or django-csvimport in particular). On the other hand, my need is more particular because my naturalistic data is distributed in several distinct tables (not counting the tables of dictionaries). Here is the schematic diagram: Model Place Place (a locality is a site with unique x / y coordinates as a building). 1-n Model Session (one data = one date and one inventory method by locality) 1-n Model Sighting (one data = one species per session) 1-n Model CountDetail (one data = 1 detail for a species: eg number of males, number of females, etc.) What I would like to get is the ability to import the data of a session with a single csv file that would populate the last two models: Observations (Sighting) and for each observation (each species observed), its detailed data (CountDetail).
