How to create multiple instance for one-to-one field in django from base model inheritance?
I have two type user model inherit from User model: class User(AbstractBaseUser): user_uuid = models.UUIDField(primary_key=True) @property def is_manager(self): return hasattr(self, 'manager') @property def is_salesman(self): return hasattr(self, 'salesman') class Manager(User): user = models.OneToOneField(User, parent_link=True) class Salesman(User): user = models.OneToOneField(User, parent_link=True) Now, the Manager could be a Salesman too.

( Django RESTful ) How to send http request without login in "api-auth/login/" in browser
Since django restful can generate apis automatically,I just have a try. In the Quickstart, it use the command line tool: bash: http -a admin:password123 http://127.0.0.1:8000/users/ I just want to send an ajax request to the api by a javascript function,but just get an error: {"readyState":4, "responseText":"{"detail":"Authenticationcredentials were not provided."}", "responseJSON":{"detail":"Authentication credentials were not provided."}, "status":403, "statusText":"Forbidden"} If I log in the "api-auth/login/" page before sending the request ,it works successful. So my question is how to include the login information in the http request. Thanks in advance. -
Django - ModelForms rendered indexed by foreignKey and that value POSTed
A simple and logical extension of the tutorial polls app would be showing several questions per page with a single 'submit' button. I've got a hybrid design that uses ModelForms for multi-field questions but individually rendered fields for single-field questions. So the standard question_set page is rendered by: {% load custom_tags %} {% block question_set %} <form action="{% url 'polls:answer' user.username %}" method="POST"> {% csrf_token %} {% for question in page_question_list %} <hr/> {% if question.answer_type == "CH" %} {% include "polls/Choice_Answer_form.html" %} {%endif%} {% if question.answer_type == "SA" %} {% include "polls/Short_Answer_form.html" %} {%endif%} {% if question.answer_type == "LA" %} {% include "polls/Long_Answer_form.html" %} {%endif%} {% if question.answer_type == "E3" %} {% include "polls/EJ_Answer_form.html" with form=forms|get_item:question%} {%endif%} {% if question.answer_type == "E4" %} {% include "polls/EJ_Answer_form.html" with form=forms|get_item:question%} {%endif%} {% if question.answer_type == "BS" %} {% include "polls/brainstorm_form.html" %} {% endif %} {% endfor %} <br/> <hr/> <input type="submit" value="Submit" /> </form> {% endblock %} I have a sense that I have missed something fundamental about how forms are supposed to work. When you create a ModelForm object and send it out to be rendered, it knows what instance (in my case, question number and user_id) it corresponds to … -
foreignkey backwards manager not working django
This seems simple.. I have a Restaurant model and Recipe model, all I want is to be able to look up all the Recipes by a certain Restaurant. I am using the backwards manager FOO_set and cant seem to make it work: models.py class Restaurant(models.Model): restaurant_user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='restaurant') class Recipe(models.Model): restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE, related_name='recipe') views.py def dashboard(request): user = request.user try: user.restaurant recipe_list = user.restaurant.recipe_set return render(request, 'usermanage/dashboard_restaurant.html',{'recipe_list':recipe_list}) When i run this i get an exception in the dashboard view. Looking at my database the user.restaurant object has recipes associated with it. If i just do recipe_list = user.restaurant it returns the restaurant object. Just when I add recipe_set it fails. Also tried recipe_set.all and all(). I have migrated everything. Django 1.11 -
PYTHON - looping the argument that have multiple information with same starts and ends
I've tried to find this solution but unable to get the correct answer. I want it to display all the id inside the text file.

Calling external HTTP api from HTTPS django+angular server on AWS
Is this possible? I am building a ecommerce site that requires calling external api service built on HTTP. My site is built on AWS EBS, with django(backend) and angular2(frontend). If I try to call the HTTP api from angular side, mixed-contents errors pops up, which is apparently the chrome browser blocking the call. Is there a way to do this? I found this answer regarding proxy, but because I'm a newbie, I don't really get how to I can proxy the call with django or angular. Thanks. -

django-allauth email verification: works for @gmail test account but not @yahoo?
This is pretty weird to me. For a while I thought the account verification was not working. I was testing it with an @yahoo.com email address. Then I decided to test it with an @gmail.com email address. I have tested both accounts multiple times and am certain I do not have a typo in the @yahoo.com email. How is this even possible? It doesn't make sense to me but if someone can shed some light on the issue I would really appreciate it. Obviously this will not fly. Thanks.

Flask debug screen not properly formatted as expected
I am following the Quickstart tutorial for Flask.

Django: AttributeError: module 'User.views' has no attribute 'User'
I have a few apps within my Django project and all of them seem to be working, except for the User app. All the apps are installed in the settings. Whenever I type "python manage.py runserver", I see a long line of code that ends with this: File "/Users/Name/Desktop/Project_Name/MyProject/User/urls.py", line 5, in <module> url(r'Home/', views.User, name='Home'), AttributeError: module 'User.views' has no attribute 'User' MyProject/urls.py from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^$', include('Home.urls')), url(r'^Application', include('Application.urls')), url(r'^Login', include('Login.urls')), url(r'^User', include('User.urls')), ] User/urls.py from django.conf.urls import url, include from User import views urlpatterns = [ url(r'Home/', views.User, name='Home'), url(r'Matrices/', views.User, name='Matrices'), ] User/views.py from django.shortcuts import render def Home(request): return render(request, 'Home.html') def Matrices(request): return render(request, 'Matrices.html') If I remove "url(r'^User', include('User.urls'))" from MyProjects/urls.py, everything is working fine (but of course I cannot access the urls from User app). All the other apps have only one "url" and only User app has multiple urls. Is that where the issue lies? Would greatly appreciate any help. Thanks!
