Django WordPress competitor?

What is the WordPress framework of the Django world? I want to throw up a site that's blog oriented and I'm contemplating brushing up on PHP 7 or just scrapping that and learning Python to throw up some kind of Django solution. Thanks for the direction.

How do you implement reset password functionality with Django Rest Framework?

Hi devs,

I'm having a bit of trouble to understand this, without DRF I did it successfully by using Django's default auth views and creating my templates but what about DRF?

Should I create a model that stores a token on the database and them verify if the token is valid for the user? If so, how to best generate this token, what to keep in mind to make the implementation as safe as possible?

Can I use Django's own mechanism which, by what I read, takes into account the last login, the current password (?), and adds some salt? This seems to be a very well thought implementation but can I borrow that mechanism into my RESTful views?

How are you (more experienced) guys doing this?

PS: I'm using only Simple JWT, not using other auth libraries like allauth or social login, don't know if this is relevant to the case.

Heroku Django application error!

Hey guys i have created my first django website! and i want to upload it through Heroku, So i followed everything they said to me and i am still getting application error wheni am trying to do
heruko open
I get an application error and as i am beginner to heruko i am frustrated to get errors! I found that i am getting error here while i do
git push heruko master
I get all things ready but a small error after deploying is done and the error is:

I also think the error is with the Procfile because i don't know what name we should type in the wsgi.py as given below:
web: guincorn whatnameshouldiwrite.wsgi

I found that we should write our app name but i have two apps in my project and i have different name for my heroku website and a different name for my project on my PC so which name should i write there?

The heroku logs looks like:

What are some simple django-based blog projects which developers starting in webdev can use?

I am looking to start a django-based blog and would like to see if people have any recommendations for "ready-made" projects. Something like this as an example: https://github.com/miguelgfierro/sciblog.

My objective is to get the blog up and running as soon as possible and customize it with time. My theoretical webdev knowledge is good although I have zero practical experience and I want to take this opportunity to learn.

What are some simple django-based blog projects which developers new to webdev can start with?

Anyone use Okta? Is it as easy as Flask-Login?

I'm just starting out with Flask, have found using Flask-Login really easy and pretty cool. But I'm worried about data protection, and thought using Okta might reduce liability. Anyone doing the same? Can it integrate with Flask-Login? The workflow for Okta looks pretty heavy - any opinions?

Best library for creating charts

Hi, I'm doing the final touches of a website (a 3-buildings warehouse) and I tought it would be cool to generate charts for a quick visualization of some of the information. I did a bit of googling to search what's the best library for Django and I found a lot of them, mainly Highcharts, Dash/Plotly, D3JS, Charts.js and many more.

What's the best (and easy to implement) library to create charts in a Django website you've ever used?

How do I configure Jupyter Notebooks to open in a browser?

When I open a Jupyter Notebook, I want it to open in a new tab of an existing Firefox window. In my ~/.jupyter/jupyter_notebook_config.py file, I try

c.NotebookApp.browser = '/usr/bin/firefox'

With this, I get a popup error from Firefox to the effect that "Firefox is already running", which isn't unexpected. You need to use command line flags to affect an already existing instance of Firefox, so I try

c.NotebookApp.browser = '/usr/bin/firefox -P default -new-tab'

When I do this, the terminal output from Jupyter gives the error

FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/firefox -P default -new-tab': '/usr/bin/firefox -P default -new-tab'

How do I tell Jupyter to open Firefox with command-line options?

Best way to handle file uploads?

Im trying to setup image uploads in a local Flask app with Flask-uploads. I think Im almost there but not able to finish it.

This is my form (using flask_wtf):

class AddBookForm(FlaskForm):
title = StringField('Title', validators=[DataRequired()])
author = StringField('Author', validators=[DataRequired()])
category = StringField('Category', validators=[DataRequired()])
image = FileField('Image', validators=[FileRequired()])

this is my template:

<form action="/upload" method="post" enctype="multipart/form-data" >
<span class="btn btn-default btn-file">
Browse <input type="file" name="image">
</span>

<input type="submit" value="Upload your image" class="btn btn-primary">
</form>

and then finally these are the important bits from views.py:

from flask.ext.uploads import UploadSet, configure_uploads, IMAGES, UploadNotAllowed

photos = UploadSet('photos', IMAGES, default_dest=lambda app: os.path.basename('uploads'))
configure_uploads(app, (photos,))

@app.route('/upload', methods=['GET', 'POST'])
def upload():
if request.method == 'POST' and 'image' in request.files:
filename = photos.save(request.files['image'])
rec = Photo(filename=filename, user=g.user.id)
rec.store()
flash("Photo saved.")
return redirect(url_for('show', id=rec.id))
return render_template('upload.html')

@app.route('/photo/<id>')
def show(id):
photo = Photo.load(id)
if photo is None:
abort(404)
url = photos.url(photo.filename)
return render_template('show.html', url=url, photo=photo)

As it stands right now when I go to /upload and fill in the form with an image the file does actually get uploaded to my 'uploads' directory in my app but this error is shown in the console:

File "/Users/david/Documents/projects/flask_store/storeapp/views.py", line 236, in upload
rec = Photo(filename=filename, user=g.user.id)
NameError: name 'Photo' is not defined

there is no object named 'Photo' but if I changed the fields in my from from 'image' to 'photo' then try and upload an image again I get no errors that time but the image doesn't get uploaded to the local 'uploads' directory.

What am I missing here?

thanks
