Using flask-oauthlib in production or authlib

Hi all. I wanted to use flask-oauthlib in a website I'm building, and got it working last night. However, I noticed that the front page of the project has a warning to use authlib instead.

Are people using flask-oauthlib in production? Are you planning to migrate to authlib?

flask-oauthlib page, note the warning:

Is there a way to add "Save and Add Another" button in crispy forms?

In Django admin there is an option Save and Add Another. How can similar function be added into crispy forms, so that entry from the first submitted form is kept?

Questions about models

Hey there!

I started out with Django and followed some tutorials. I do know some things about databases but not too much.

My questions:
Let's say we have two models.
1. Bookstore
2.Book

Does bookstore refer to a lot of book ojects
Or
Does a book refer to a bookstore object?

Thanks in advance!

How to pass data from a button in the html page to a database?

I have to code a page that has a question, and 3 options to answer.
I have a page that display the questions and the 3 answers of every question, the questions are already stored in the database. Now my problem is how can I save the user choice for that specific question?
I have created a model to save the user choice, the user id, and the question id. But I'm having trouble to get witch button the user clicked for the answer.

#Here is the model
class UserVotes(models.Model):
id_user = models.CharField(max_length=10)
id_question = models.CharField(max_length=10)
choice_user = models.CharField(max_length=10)

#Here is the view
class QuestionListView(generic.ListView):
model = Question

def voteQuestion(request):
if 'Yes' in request.POST:
idQuestion = request.question.id
idUser = request.user.id
p = UserVotes(id_user=idUser, id_question=idQuestion, choice_user=1)
p.save()
elif 'No' in request.POST:
#same thing, the difference is the value of choice_user will be 2.

#the url.py
url(r'^question/$', views.QuestionListView.as_view(), name='question'),

#the html page
<button type="submit" name="Yes">Yes</button>
<button type="submit" name="No">No</button>

I've got several errors, the last one that came up is a http 405 error, method post not allowed.
If someone can help please, I've spend 2 nights and 1 day on this already haha. Thanks!!

RabbitMQ Disconnects

I'm using RabbitMQ(pika) and django on windows, and after the socket sits idle for some time, it disconnects. I allready tried : setting the connection parameter "blocked_connection_timeout" to none.

I also tried check if the connection was open and if not, reconnect, but this always leads to an ConnectionResetError.

Any ideas?

[AF] Which frontend framework works best with Flask?

/u/Cran3kill inspired me to ask [the same question](https://www.reddit.com/r/flask/comments/8ft6e9/which_front_end_with_flask/) he did yesterday with some additional information. All the answers like
> react!

or

> jinja with react was a pain

has no value without a context, so I give you one.


--------------------------------------------------------


So I'm building my data visualization/scrollytelling blog. It's a side project for myself, so I'm free to choose anything I want, but I have no idea what I want.

I know I will be experimenting with d3.js and many other libraries, but I have no idea where to begin with the *general* front-end. I know I can set up basic frontend with the Flask itself, but I want to learn how to separate backend from the frontend completely.

I've used JS and jQuery before in WordPress but that's that. I'm tired of watching all these comparisons of Angular vs React vs Vue. I don't really understand what's the difference and I just need to pick one, create a working environment and play around with d3.

This question may seem off-topic but it's really hard to decide **which framework works best with Flask** when you have no experience with a frontend at all. I've used the search tool, there are some questions about certain frontend frameworks but there's no general one and almost all of the github examples are dead.

How I see it:

On my VPS, EC2 etc. I run at least two servers:
Backend server: nginx -> uwsgi or gunicorn -> Flask (maybe with celery, also caching DB responses here).
Frontend server: ??, usually fetches data from Flask endpoint

Request - Respons cycle.
client -> domain -> dns -> frontend **??** -> server (Flask-RESTful etc.) -> frontend drawing library from db response or cached response -> client.

So I believe I need JS framework to do some routing and provide this 'look and feel' before d3js draws something on it.
I know I could've done that with Flask and Bootstrap, but once again, I want to separate frontend from backend in order to learn JS and how to structure an app like that.
I want it to be fast and light. I don't need *the newest* or *the best*. I probably don't want it to have all the tools in the world since that's why I dislike Django.

I really can't decide on my own. It requires way too much experience to know which one to pick and it seems like frontend battle never ends. Your advice and examples are greatly appreciated.

### Edit: I made a full circle a couple of times and I've decided to pick **vue**. I like its learning curve, components approach, origin and this [udemy course](https://www.udemy.com/vuejs-2-the-complete-guide) along with documentation should cover everything I need. Thanks y'all for help.

Is the official flask tutorial correct?

I'm reading:

http://flask.pocoo.org/docs/1.0/tutorial/factory/

Is this tutorial correct?

I copy the code verbatim to `vink/__init__.py`

I do the exports:

export FLASK_APP="vink"
export FLASK_ENV=development

I run:

flask run

I get:

Error: The file/path provided (./vink) does not appear to exist.
Please verify the path is correct.
If app is not on PYTHONPATH, ensure the extension is .py

I also tried:

export FLASK_APP="vink/__init__.py"
flask run

and I get:

Error: Failed to find application in module "vink". Are you sure it contains a Flask application? Maybe you wrapped it in a WSGI middleware or you are using a factory function.


my tree looks like so:


vink
├── instance
│ └── config.py
├── setup.py
├── tests
└── vink
├── __init__.py
├── __pycache__
└── config.py

Flask won't send emails

I'm getting this error:

ERROR:flask_appbuilder.security.registerviews:Send email exception: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:777)

When trying to register a user through [this otherwise excellent Flask boilerplate](https://github.com/dpgaspar/Flask-AppBuilder). The weird thing is, I got the same error when I was fiddling with a different boilerplate.

What try?
