Thank you for your great Flask Tutorial.

Hi Corey, not sure if you're still reading these comments. Loving the tutorials. Am up to the end of the video (7) for changing the user's profile image. All works until this part.

Pillow is installed for PIP. Run the code and I get the following error.

website_1 | File "/logrr/logrr/blueprints/login/views.py", line 74, in accountPage
website_1 | picture_file = save_picture(form.picture.data)
website_1 | File "/logrr/logrr/blueprints/login/views.py", line 57, in save_picture
website_1 | i.save(picture_path)
website_1 | File "/usr/local/lib/python3.7/site-packages/PIL/Image.py", line 2004, in save
website_1 | fp = builtins.open(filename, "w+b")
website_1 | FileNotFoundError: [Errno 2] No such file or directory: '/logrr/static/images/profile_pics/757b0bf5ed6b98cb.jpg'

I check and sure enough, in the profile_pics folder there is no file. I changed permissions so that all users can access the folder with full access so it can't be that.

Line 74 is calling the save function:
picture_file = save_picture(form.picture.data)

Line 57 is the actual save line in the function:
i.save(picture_path)

What could be wrong? I'm a little stumped. Thank you

Hello!
In your Django code snippets for "06-User-Registration-Form", I'm getting this error when I try to create new user with existing username.

ValueError: The view user_auth.views.register didn't return an HttpResponse object. It returned None instead.

This is my forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User

class UserRegisterForm(UserCreationForm):
    email = forms.EmailField() 
    class Meta:
        model = User
        fields = ('first_name', 'last_name', 'username', 'email', 'password1', 'password2',)

This is my views.py

from django.shortcuts import render, redirect
from django.contrib import messages
from user_auth.forms import UserRegisterForm

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f'Account created for {username}!')
            return redirect('index')

    else:
        form = UserRegisterForm()
        return render(request, 'register.html', {'form':form})

Can you please help me to figure out this problem?
Thanks in advance.

Am attempting to follow along, however I did skip videos 6-11? on the django series. I feel kind of foolish, however I am experiencing this 500 error on the homepage, however, the other pages work as expected. (This is a live version on heroku, but I have my site disabled, as I need to actually add content, and get the homepage to work first :D)

I took a look at the final deployed django website on heroku to see how the images were displayed in the HTML. I saw that the src parameter of the img tags look something like

<img class="rounded-circle article-img" src="https://django-blog-bucket-experiement.s3.amazonaws.com/profile_pics/logo.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&amp;X-Amz-Credential=AKIAI5JMO5BA2FV5LMWA%2F20190816%2Fus-east-2%2Fs3%2Faws4_request&amp;X-Amz-Date=20190816T212801Z&amp;X-Amz-Expires=3600&amp;X-Amz-SignedHeaders=host&amp;X-Amz-Signature=4319df2a3691fd7641725df9efc918a7458afe7d55370f1c06cb0fd6bd0252b6">

This displays both the

• bucket name (django-blog-bucket-experiement)
• AWS Access Key ID (X-Amz-Credential=AKIAI5JMO5BA2FV5LMWA)

On AWS it says that it is important to not give out the Access Key ID.

Is this a security issue? If so, how can it be changed?

Hey,

I am currently working on your tutorial titled: "Python Django Tutorial: Full-Featured Web App Part 12 - Email and Password Reset"

I downloaded the code_snippets for Part 12 and I can't seem to receive any emails for password reset.

What have i tried:
I have already set "Allow less secure apps: ON" in my google account. I tried looking everywhere on Google and the answers provided are mostly asking me to try to Allow less secure apps on Google. It's been 24H I can't seem to find what have I done wrong..

I also tried using the EmailMessage class at my views.py. I am able to send email to myself. I don't think there is any issue with the authentication of my email.

all the https and www's have been removed already.

I do not have a sign up for https://images.unsplash.com. So I change the url to github and wound up with one file.

from:

def download_image(img_url):
    img_bytes = requests.get(img_url).content
    img_name = img_url.split('/')[3] #<-------------------
    img_name = f'{img_name}.jpg' #<-------------------
    with open(img_name, 'wb') as img_file:
        img_file.write(img_bytes)
        print(f'{img_name} was downloaded...')

To:

def download_image(img_url):
    img_bytes = requests.get(img_url).content
    img_name = img_url.split('/')[-1] #<------------------
    #img_name = f'{img_name}.jpg' #<------------------
    with open(img_name, 'wb') as img_file:
        img_file.write(img_bytes)
        print(f'{img_name} was downloaded...')

I am just curious about the repo, no readme and no description. But so many stars.

Corey,
thanks for your imazing playlist at youtube, but this is something i did not quite understood ! why var update (first) did not pass to the email!
it does passed to full name function! but it does not to email!!

HI Corey,

Thanks for posting this django tutorial. I have finished the tutorial and am now working through making my own project with a similar structure and noticed a few issues that may or may not be relevant.

line 23 in base.html - should it be navbar-fixed-top instead of fixed-top. I don't think it will create issues for the tutorial but incase you want to add it for completeness.

Greetings, Corey! Colud you please help a newbie find an answer? Something has changed in BS, so that:

i just completed mr coreyMSchafer vedio tutorial Flask dev environment. but i get this error message.

on init.py already write the code :

app.config['MAIL_SERVER'] = 'smtp.googlemail.com'

app.config['MAIL_PORT'] = 587

app.config['MAIL_USE_TLS'] = True

app.config['MAIL_USERNAME'] = os.environ.get('EMAIL_USER')

app.config['MAIL_PASSWORD'] = os.environ.get('EMAIL_PASS')

I wrote the same exact issue, checked my environment settings, printed out everything, and they still give out the same OSError.

i do register, and click sign up then

the input is successful but does not go to the login form

How to add links( like google.com) to a post (content). I tried doing it but failed

suggested enhancement:

function conda_auto_env() {
  if [ -e "environment.yaml" ]; then
    ENV_NAME=$(head -n 1 environment.yaml | cut -f2 -d ' ')
    # Check if you are already in the environment
    if [[ $CONDA_PREFIX != *$ENV_NAME* ]]; then
      # Try to activate environment
      source activate $ENV_NAME &>/dev/null
    fi
  else
    source deactivate
  fi
}

hello my name is Amani , how can you connect flask app with existing database

I noticed there doesn't appear to be any tests in the Flask_Blogs project

Took codebase from : https://github.com/CoreyMSchafer/code_snippets/tree/master/Decorators
I added below snippet at the end of decorator.py and it should have created log file named as check_kw.log
However, it didn't do it. It just appended the logs created by this function to display_info.log file.
Is there anything else need to change in my_logger?

@my_logger
@my_timer
def check_kw(*args, **kwargs):
    time.sleep(1)
    print('check_kw ran with arguments ({}, {})'.format(args, kwargs))


keywordargs = {"arg3": 3, "arg2": "two", "arg1": 5}
check_kw(**keywordargs)

Hi Corey,

Your tutorial is excellent, helped me a lot, thank you so much.

I followed your steps in tutorial 2 for Flask Blog, when I used bootstrap the webpage styling did not change, all the navigation bars are stuck together. I am not sure why?

By the way I am using python 2, does bootstrap require python 3?

Thank you,
Ling

I am following your youtube python tutorials for Python/Flask_Blog/ and it is fascinating. Wondering if you are planning to put additional videos for unit testing.

Thank you!

@CoreyMSchafer Kinddly help me to solve this issue i am not finding where is the issue. I am learning Flask_Blog tutorial
Thank you

Hi @CoreyMSchafer is there a requirements.txt file that you can add to the flask_blog project? To help setup a venv with all the right packages installed from the get-go...

Not an issue but a question -- When I attempt to use models in forms, I get the error "No application found. Either work inside a view function or push" when running the application. Is there a way to use and query models within forms?

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField, TextAreaField
from wtforms.validators import DataRequired
from flaskblog.models import Post


def posttest():
    return Post.query.first().content


class PostForm(FlaskForm):
    title = StringField("Title", validators=[DataRequired()])
    content = TextAreaField("Content", validators=[DataRequired()], default=posttest())
    submit = SubmitField("Post")

Going through the Django blog project. I tried a few of the projects and all of the ones I tried (01, 03, 06, 12) and all of them fail when creating a super user from the command line using "python manage.py createsuperuser". It seems like the only time it works is just as you create the django project.

First off, thank you for doing these tutorials; it has really helped me with web development. However, I have had an issue in your Python Flask tutorials at tutorial #11. I always get the error:

AttributeError: 'Blueprint' object has no attribute 'json_encoder'

I am able to access the website, but it shows the above error.
The only solution I got was by removing the Secret_Key in CONFIG class. But when I access my account, it throws another error saying that it needs the secret key. I have all my dependencies imported prior to your requirements.txt; I'm not sure what's wrong.

In part 3 flaskblog.py I'm getting an error stating, "No module named 'forms.'" I resorted to copy/paste the code from here but still getting the error. I'm stumped. I copy/pasted the flaskblog.py, register.html, and login.html code, but to no avail.

What am I getting wrong?

Thanks

Thanks for bringing such great tutorial, I am really interested in how to change the Profile update function to classed based view.

I did some research, the things covered are mostly based on one form, not combo of two forms, does anyone know how to solve it? thanks

def profile(request):
    if request.method == "POST":

    u_form = UserUpdateForm(request.POST,instance=request.user)
    p_form = ProfileUpdateForm(request.POST,request.FILES,instance=request.user.profile)
    if u_form.is_valid() and p_form.is_valid():
        u_form.save()
        p_form.save()
        messages.success(request,"Your accunt has been updated, you are now be able to log in !")
        return redirect('profile')
    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)
    context = {
        'u_form':u_form,
        'p_form':p_form
    }
    return render(request,'users/profile.html',context)

I tried with updateview, detailview, but all fails

thanks

Hi there.

I was reading the code of flask blog app and in logout route definition isn't login_required should be used? Like:

@app.route("/logout")
def logout():
    logout_user()
    return redirect(url_for('home'))

to

@app.route("/logout")
@login_required
def logout():
    logout_user()
    return redirect(url_for('home'))

Thanks for all your amazing tutorials.

Hi Schafer,

It seems the Yahoo Finances API is not working anymore, but I believe this link will work to you at least for your demo :

https://api.worldtradingdata.com/api/v1/stock?symbol=AAPL&output=json&api_token="YOUR API TOKEN"

You only need to create an account in https://www.worldtradingdata.com. But at least it is free! Or use any other API json file.

Hi,
Thanks for the code and youtube tutorial. They are awesome.
I notice that the code of the video is different from the github one.

For instance the class methods are not there.
Would it be possible to share it?

Thanks again,
