Django Rest Framework Token authentication with Social auth login
In my Django Rest Framework application, a Token is generated for every user that logs in for the first time into the application using signals. Now I can use this token (By manually going to database and grabbing the token) to make API calls to the view that have authentication_classes = (TokenAuthentication,). Can someone explain me how can I provide this token to the user securely when the (OpenID) login was successful. Django Rest Framework supports something like: from rest_framework.authtoken import views urlpatterns += [ url(r'^api-token-auth/', views.obtain_auth_token) ] But, this obtain_auth_token view only supports post request which takes username and password, which is not the case with my application. Please correct me if there are any flaws in my workflow. -
Can't find any modules in Django project
I've been following a Django tutorial and initially had created virtualenv and a requirements file in it. Project was halfway and in working state. Today I activated virtualenv successfully and tried python manage.py runserver to get error ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? I realized it's not finding Django and just to be sure checked my requirements.txt file (which confirmed right Django version). Tried to reinstall it from the file using pip3 install -r requirements.txt (tried using just pip too) to get another error -- ModuleNotFoundError: No module named 'pip' It seems the environment is unable to find any of the modules. I tried to reinstall pip also just to be sure, but then it couldn't find apt-get command. OS: Mac OSX El Capitan 10.11.6 Python: 3.6.2 Django: 1.10.3 (in requirements file) -

Send template form data to view via URL
I'm trying to build a wiki search app in django and am having trouble creating a MVC link with a template that has a form with POST method. Essentially, my search form, search_form.html looks like this: {% extends 'layout.html' %} {% block title %}Wiki Search | Search {% endblock title %} {% block content %} <form action = "{% url 'search_results' search_term %}" method="post"> Search for:<br> <input type="text" name="search_term" value=""> <br> <input type="checkbox" name="is_date" value="date">I'm searching for a date (e.g. 02/10) <br><br> <input type="submit" value="Search"> </form> {% endblock content %} The end view needs to evaluate the checkbox value (name=is_date) and the text input (name=search_term). I am passing it to URL named 'search_results' which is defined in my urls.py: from django.conf.urls import url from . import views urlpatterns = [ url(r'search/(?P<search_term>[.\-\_\w\d\s]+)/$', views.search_results, name='search_results'), url(r'search/$', views.search_form, name='search_form'), url(r'^$', views.index, name='index'), ] my search_results url has a regex with a named capture of search_term. I am assuming that this is filled by me referencing the template's form's text input (named search_term). Finally, this URL references views.py's search_results function which is: from django.shortcuts import render from django.http import HttpResponse, HttpRequest from .models import Search # Create your views here. def index(request): #return render(request, … -

how to use ajax with graphql using get method?
I am trying to follow this documentation about django and graphql https://www.techiediaries.com/django-graphql-tutorial/graphene/ I am only half way to where we can do testing with the graphql view and make our queries. Then I stopped and trying to do some front end work to make query with ajax been reading https://blog.graph.cool/how-to-use-graphql-with-jquery-51786f0a59cb Even though in that blog, it's using post. I believe using get shouldn't be too much different. So I tried making query into a string then JSON.stringify them to pass it over to the backend django but I keep on getting error this is the error I have XMLHttpRequest cannot load localhost:8000/graphql/?{"query":"query { allProducts {id sku title description } }"}.

How to define a subclass of ListBlock with fixed contents?
Is there a better way than this to make a subclass of ListBlock with fixed contents? class MixedMediaCarouselBlock(blocks.ListBlock): """ A hghly streamlined CarouselBlock which displays only Images and/or Videos. """ def __init__(self, child_block=None, **kwargs): child_block = blocks.StructBlock([ ('image', ImageChooserBlock(required=False)), ('video', EmbedBlock( label="Video URL", help_text="Paste the video URL from YouTube or Vimeo." " e.g. https://www.youtube.com/watch?v=l3Pz_xQZVDg" " or https://vimeo.com/207076450.", required=False ) ), ]) super(MixedMediaCarouselBlock, self).__init__(child_block, **kwargs) class Meta: template = 'core/blocks/mixed_media_carousel_block.html' label = 'Mixed Media Carousel' icon = 'media' It feels really hacky to do it this way, but I can't find any other obvious method, because ListBlock requires that child_block argument to its constructor, while other block types do not. The reason I want a ListBlock subclass is to use it as the single block type in a StreamField in one of my Pages: class News(Page) assets = StreamField( MixedMediaCarouselBlock(), help_text='Pick one or more images/videos to place in the sidebar of this article.' ) Maybe I'm just doing this wrong? -
Access related ManyToManyField data pre-save in the Django Model.save method
We would like to access related ManyToManyField data pre-save within the Model.save method, however the data isn't available yet via the Django ORM because it's related ManyToManyField data and doesn't get set until post-save of the primary record. Here's some example code of the relationship and where the related ManyToMany records are accessed in Model.save class Friend(models.Model): name = models.CharField(max_length=50) class Person(models.Model): name = models.CharField(max_length=50) friends = models.ManyToManyField(Friend) def save(self, *args, **kwargs): friends = self.friends.all() # 'friends' is an empty QuerySet at this point # I'd like to do something with friends here, # but it gets set after save super(Friend, self).save(*args, **kwargs) Example use case where friends are passed in on save: friend = Friend.objects.all()[0] friend2 = Friend.objects.all()[1] friends = [friend, friend2] Person.objects.create(friends=friends)
