Setting up Mimetype when to show a mp4/webm in all browsers in Django
I'm trying to understand how I can have my website properly display - specifically a banner video. I think the issue relates to Mimetype - It works from my computer but not when server from a server.

AllAUTH Django not redirecting to Home Page
I am trying to make a Django 1.11.5 Application including the Facebook Login using AllAuth. Settings.py SITE_ID = 1 LOGIN_REDIRECT_URL = '/' SOCIALACCOUNT_QUERY_EMAIL = True SOCIALACCOUNT_PROVIDERS = { 'facebook': { 'SCOPE': ['email', 'user_posts'], 'AUTH_PARAMS': {'auth_type': 'reauthenticate'}, 'METHOD': 'js_sdk', 'FIELDS': [ 'id', 'email', 'name', 'first_name', 'last_name', ], 'EXCHANGE_TOKEN': True, 'VERIFIED_EMAIL': True } } ACCOUNT_LOGOUT_ON_GET = True The problem is: When I click on the login through link a box appear for password. If I cancel the box then the error or cancel template appears on the browser like the below: I want that this page should not appear. Instead, the URL must redirect to HomePage. Hence I tried the following in my URLS.py url(r'^accounts/social/login/cancelled/$', RedirectView.as_view(pattern_name='homeIndex', permanent=False)) But has no effect on the browser. Please let me know what I am missing in the implementation to improve my functionality. -

How to deploy website changes in Django
Recently, the web developer that created our website has gone a-wall. Our company is in the process of sourcing a new developer that knows Django and Python. I am a Microsoft developer with little to no Django experience. However, I do know a little unix and have worked with linux and apache before. We need to make a minor update to our contact details page as we have moved office. The developer originally hard coded this page so we can not update this page via the CMS. I have located the file on the server and made the address updates but I do not know how to deploy it so it reflects on the live site. Can anyone assist me in doing this? I'm ssh into the box and doing everything via the terminal. Cheers, Ben -
django-taggit issue with url for blog/tag page & display all tags

Tag an existing model and save it as a new model object in Django
I'm working on a django (1.10.5) project in which I need to build a logic as: We have a model as "Article" and upload articles by admin already.

Python Django equals in function arguments. Setting the variable dynamically
I think this is called "Positional arguments" or the opposite or keyword arguments. I have written a script in Python Django and rest framework that has to take in parameters from the user and feed it to the Amazon API. Here is the code; page = request.query_params.get('page'); search = request.query_params.get('search'); search_field = request.query_params.get('search_field'); search_index = request.query_params.get('search_index'); response = amazon.ItemSearch(Keywords=search, SearchIndex=search_index, ResponseGroup="ItemAttributes,Offers,Images,EditorialReview,Reviews") In this code the text Keywords=search varies. That is. It could be like this Actor=search, Title=search, or Publisher=search I am not sure how to make the Keywords part dynamic such that it changes to the user's input such as Actor, Title, or Publisher -

How can I re-label the "Password" field on the Django 1.11 login page?
I want to customise the appearance of the "Password" field on the Django 1.11 login page. Specifically, I want to change the label from "Password" to "Passphrase" while maximising re-use of default Django code. For other forms I have done this subclassing as follows: from django.utils.translation import ugettext_lazy as _ from x import BaseForm class CustomForm(BaseForm): def __init__(self, *args, **kwargs): super(CustomForm, self).__init__(*args, **kwargs) self.fields["fieldname"].label = _("Custom label") ...but simply subclassing AuthenticationForm has no effect, so I assume I have to hook it up somehow. And/or subclass LoginView? -
Inactive django account with djoser
Hi guys I am trying to log in with an inactive account, I used Djoser, Django Rest Framework but I need to show the correct message to the user. I was testing the API with an inactive account, but I always receive this message: Unable to login with provided credentials. I was studying the code of djoser, and I found that this line of code (https://github.com/sunscrapers/djoser/blob/master/djoser/serializers.py#L95) is never gets execute, because the authenticate method always return None when the user is not active. I can solve the problem with Django ORM, but I think that's is not a fancy solution. I hope can you help me. Thanks in advance. -

Django Rest Framework creating instance instead of updating

Are there conventions for naming Django project, setting and main app folders?
My Django site currently looks like this: my_store (project folder) docs app_1 admin.py apps.py ... app_2 store (main app folder) my_store (settings folder) settings.py urls.py ... Where: my_store is the name of my project app_1 and app_2 are potentially reusable apps store contains project-specific logic and configuration (likely not reusable) Are there established conventions for giving distinct names to each of: the project folder (my_store) the settings folder (my_store) the main app folder (store) -- I've seen a few examples of calling this "main" De facto / popular conventions welcome, but documented / authoritative conventions preferred. -
