[UPDATE] FlaskCon is coming!

# Update: FlaskCon has been postponed until early July, and the deadline for papers has been adjusted to June 7th accordingly.

The chosen dates right now are **July 4th - 5th**. However, since this conflicts with a certain popular holiday \[bald eagle screams distantly\], I'm going to make sure that this date is firm. I'll update this post when I receive word.

I know you'll all use the extra time to make your wonderful presentations even more perfect! :\^)

*Original post:*

Hi everyone!

Some awesome folks from the Python/Flask community have been putting a *ton* of work into organizing the inaugural **FlaskCon.** FlaskCon is an online conference which is:

* **100% remote,**
* **100% free,**
* **and 100% community-driven.**

FlaskCon will go live on ~~June 26th, 2020~~ **July 4th, 2020**. It will focus on technical discussions and Flask evangelism. Best of all, **everyone is invited to participate!**

If you have an interesting idea for a Flask-related talk, want to show off something unique you've made, or anything else that you think people will want to hear about, [**sign up to participate here**](https://sessionize.com/flaskcon). A lot of great people have signed on to review talk proposals, including Pallets members and the author of the Flask Mega-Tutorial.

Ploomber CI - A Github action to run your Data Science pipeline on each push

Hi,

We just released Ploomber CI, a Github action that runs Data Science pipelines on each push to ensure reproducibility. It is powered by our library [Ploomber](https://github.com/ploomber/ploomber), hence it can handle arbitrarily complex pipeline structures with multiple tasks and dependencies.

How do I avoid hardcoding a django form?

```
class UserAnswerChoiceForm(forms.Form):
CHOICES = (
(None ,None),
(1, 'Disagree strongly'),
(2, 'Disagree a little'),
(3, 'Neither agree nor disagree'),
(4, 'Agree a little'),
(5, 'Agree strongly'),
)
answer_for_question_1 = forms.CharField(
widget=forms.Select(choices=CHOICES))
answer_for_question_2 = forms.CharField(
widget=forms.Select(choices=CHOICES))
and 43 more...

```

The logic is handled like so


```
if form.is_valid():
new_answer_group = SelfAnswerGroup.objects. create(user=request.user, user_profile=request.user.profile,)
for x in range(1, 45):
answer = UserAnswerChoice.objects.create(
user=request.user,

How much to rely on extensions?

As with my recent troubles with Flask-User, I'm trying to under how to balance the dependency on Flask Extensions, with not having to reinvent the wheel.

I first picked up Flask through a Udemy course, from which the instructor seemed to build most of the functionality from scratch, e.g. creating methods for the Database model to query from MongoDB, creating users and inserting their information.

But after the course, I've chanced upon the world of extensions, but I guess not all of them are actively maintained & may not exactly fit the requirements. Feeling slightly exasperated spending half a day trying to get Flask-User to register users into my MongoDB Atlas, but to no avail. Googling also didn't seem to yield much results...

How much do you guys utilize extensions?

Running a jupyter notebook on a server.

Hi, hello everyone,

I'm a physics teacher from Brazil and because of the quarantine i'm trying to make the lab classes on a virtual environment . I coded a physics simulation on python in a jupyter notebook file and i'm trying to make it accessible on a web page, like google **Colaboratory** (I tried to use google **Colaboratory, but some functions just wont work)**. Does someone know a guide/tutorial to make a running jupyter notebook file on a webpage ?

rq worker and redis

Hi,

i just startet to work with redis and rq worker. my test script is running and rq worker and the redis server are processing my tasks. everything runs perfectly fine. but the tasks I want to create for my project can take up to 12 minutes. they wait for a status on a different server.

let's say, i have 4 tasks.

task #1 takes 8 minutes

task #2 takes 12 minutes

task #3 takes 4 minutes

and finally task #4 takes 7 minutes.

is there a way to check if task #1 is done and if not put task #1 at the end of the queue and check task #2 and so on and so forth. Or do I have to wait until task #1 is done to continue with task #2.

In my perfect world I would get my feedback in the following order:

task #3, task #4, task #1 and finally task #2

thanks in advance

Missing ipynb files

Hi!

Im somewhat new to Python and Jupyter Notebook. I had some ipynb files created around 5 months ago. Few days ago I changed the location of the folder holding those files and now I can't find most of those ipynb files! Only 6 out of 20 files are somehow still there while the others are completely gone :| Can someone please explain why this happened and how to resolve it?

I obviously tried googling this, but couldn't find anything helpful.

Thank you :)
