build-a-saas-app-with-flask's Issues

System health monitoring

Everything will be ran in a container when it comes to deploying it. Implement a way to get various health checks on each container and the overall system.

They will be accessible through the admin dashboard.

how can i configure postgresql over here can you help me out

I've been playing around with the code and tried to remove the billing and streaming, this meant I also remove the click commands for the billing and streaming features. Though now when I try to run it I am getting this error,

Error importing module add:
add

Do you know what may be causing click to not be able to import the commands and do you have any ideas about how I might fix this bug. Thanks

Cannot access admin page

Hi Nick
I make some change and now can't access admin dashboard
[email protected]/password is incorrect
where is admin username/password defined?

Thank you

why not django?

I don't know,why you choose Flask rather than Django? and;
does my subscription and learning from your course can help me though, familiarize django tech stack

Add page to display real time tweets

The real time tweet page will:

Make a websocket connection to the websocket server
Listen for events and then publish them as they come up

ImportError: No module named abc

...

Add admin dashboard blueprint

The blueprint will include functionality such as:

Add an admin toolbar to the top of the page
Restricted to only admins
A dashboard page to show stats about:
- How many users and subscribers we have
- How many issues are open
Search, filter, bulk actions for users and issues

Task worker monitor

It would be nice to be able to check the status of your task worker(s). Implement a way to view metrics about your tasks and make it accessible through the admin dashboard.

    Is the server running on host "192.168.99.100" and accepting
    TCP/IP connections on port 5432?

The docker daemon is running (verified it by running hello-world again) and I have check the ip address using;

docker-machine ip default

Any suggestions on how I might fix this and what is causing it ?

EDIT - Following is the error that is arises when I try to process payment in the app;

celery-beat KeyError 'Scheduler'

I'm trying to test the periodic celery tasks. However, when I try to start the celery container I get the following error:

Removing corrupted schedule file 'celerybeat-schedule': error(22, 'Invalid argument')
Traceback (most recent call last):
    File "/usr/local/lib/python3.7/site-packages/kombu/utils/objects.py", line 42, in __get__
	return obj.__dict__[self.__name__]
    KeyError: 'scheduler'

As per the course notes, I have tried to amend the docker-compose.yml to run the celery and beat worker independently:

celery:
   build: .
   command: celery worker -l info -A snakeeyes.blueprints.contact.tasks 
   env_file:
     - '.env'
   volumes:
     - '.:/snakeeyes'

 celery_beat:
   build: .
   command: celery beat -l info -A snakeeyes.blueprints.contact.tasks
   env_file:
   - '.env'
   volumes:
   - '.:/snakeeyes'

However I still get the same issue. I have also tried to delete the celerybeat-schedule file which seems to be corrupted however upon running docker-compose up the file gets recreated which throws the same error.

Below is the full trace back:

Adding Custom CSS and JS

What's the best way on adding custom .css and .js files,
I added my files into assets, but they don't seem to be in effect.

Custom error pages

Custom error pages for 404, 500 and 502 status codes.

A more efficient and better webpack config

There are a number of things that can be done in the webpack config to further improve performance in development mode, such as:

If in development mode
- Skip minifying files (small but reasonable win)
- Skip re-parsing vendor JS files (this will be a big win in dev mode for JS heavy apps)

Additional loaders will also be added to do things such as:

Automatically add CSS vendor prefixes based on the "Can I use?" website

CSRF problem

hello nickjj

i am seeing csrf token missing or invalid error in production server

i thought maybe because of import error in all Forms.py:

import Form from wtforms << no csrf protection
import Form from flask.ext.wtf << usually do like this

see here last section Troubleshooting: http://flask-wtf.readthedocs.org/en/latest/csrf.html

But still not working! i am seeing csrf error when i try to login.
i have secret key in settings.py file

Exception handling

Full stack traces and all relevant details will get e-mailed to you when exceptions occur.

Allow users to save their locale and timezone

Locales and timezones should be not be 2nd class citizens in a SAAS app. Introduce settings to allow users to set both in their account settings.

Refactoring the code base

The entire app will be combed over, function by function with intentions to move code around into places that will allow for better maintainability and easier customization.

This will end up doing various things like moving logic out of the views and into either the model or libraries and so on.

Deleting users should cancel their membership

Currently bulk deleting users does not delete their membership on the payment gateway. The bulk delete routine should be overridden to also delete them on the payment gateway's end if they are a subscriber.

SMTPAuthenticationError 534

When trying to send an email through the smtp.gmail.com server I receive a notification saying that the app doesn't meet modern security standards.

What can I add the bring Catwatch up to these standards so I can safely use the Gmail SMTP server?

Admin functionality for managing billing components

The admin blueprint will be updated to include:

Admins can terminate any user's subscription
Admins can view subscription info for any user
Admins can create and manage coupons

TO THE MOON

A new theme based on Bootstrap

I've had a number of requests to move away from Google's starter kit, and instead use Bootstrap.

I didn't want to impose any design designs initially, and Google's starter kit is still written in SASS so it would be pretty easy to move to Bootstrap but that would still leave you guys having to rip it all out and change a ton of templates.

The entire app will get switched to the latest version of Bootstrap.

OSX related issues

I had many issues getting the Docker containers going on my Mac, so I thought I'd share some workarounds here. I'm fairly new to Docker, so there may be mistakes! There are a couple of project-related issues at the end too :-)

First, install Docker, boot2docker and Docker-compose.

There are problems with the permissions on vboxsf mounts, preventing postgres from writing to /var/lib/postgresql/data. You need to either change the access permissions, or mount to your home folder using nfs instead. The latter is described here: http://syskall.com/using-boot2docker-using-nfs-instead-of-vboxsf/

You should also add "$(boot2docker shellinit 2> /dev/null)" to the bottom of your ~/.bash_profile.

Next, you may need to fix the ip/certification bug. To edit the profile, run:

$ boot2docker ssh -t sudo vi /var/lib/boot2docker/profile)

Now when you reach the initialization stage, you need to issue:

$ run assets build

to create the manifest.json first, before issuing run to see a list of what's available.

You then may need to replace all instances of "website_postgres_1" in cli/commands/cmd_db.py with the correct name of the postgresql host (eg. "buildasaasappwithflask_postgres_1").

The last issue is unresolved. When I try to initialize the database, I get the following error:

So now I'm stuck!

Thanks for the great project, Nick. I look forward to the finished product!

Issue form does not actually mail anything

Implement the support form mailer. This was a place holder in the earliest releases.

Add twitter module

The twitter module will be accountable for:

Use Twitter's streaming API to get cat tweets
Send the data obtained by the API to the broadcast module

Enhanced app level request logging

More useful information will be logged for each request, such as request duration, endpoint hit, etc..

Create a Dockerfile

Previously there was no Dockerfile because the app was running inside of virtualenv. This is ok for development because you'll likely want your app code to be on your workstation directly so you can use debuggers and other useful tools.

However in production your app along with celery will be in their own container. Implement a Dockerfile that allows you to build both an app and celery docker image.

Activity tracking for users

The user model should be adjusted so we can keep track of:

How many times the user signed in
Current sign in date / Current sign in IP address
Previous sign in date / Previous sign in IP address

Illegal instruction: 4

Trying to install the project, I get:

# docker-compose up
Illegal instruction: 4

For sure is only that I'm a complete Docker newbie. Probably I didn't "Edit docker-compose.yml and setup a local volume for Postgres/Redis" properly, as I just installed Docker from the Docker site installer for Mac OSX and executed the "Docker Quickstart Terminal" binary.

Getting a ImportError when running with docker compose

Getting a ImportError: No module named snakeeyes.blueprints.contact when trying to use it with docker. I have not changed any code. Just pulled the code and ran it as in the document.

Let me know if you have any idea how to solve this.

Several questions for solution evaluation

Hello,

We've just started looking for ways to provide our solution (Orienteer) as a service.
Your project looks great and seems to be exactly what we needed in!
But there are several questions:

What is the status of this project? Is it recommended for production or not yet?
Are there any projects which use this solution? Could you please share some links?
Does solution support plans which based on different Docker images?
Does solution support plans which based on different limitations (RAM, SSD)?
Can solution automatically buy additional hosts in digital ocean if required?
Does solution provide API for automatic provisioning and activation of a service?
Does solution support smooth switch of a plan?
Does solution support automatic assignment of DNS per deployed app?

Thanks for your great project!

Add loadbalancers in front of docker images to support scaling of different tiers

It would be great to add an LB infront of web & db services in order to use docker scaling functionality docker-compose scale web=2 , docker-compose scale db=3

Error importing module db:

Hi Nick,
I'm trying to run the app on OSX.
When I try to initialise the database I keep getting:

elieh$ run db reset catwatch catwatch_test
Error importing module db:
db

I ran docker-compose up beforehand.
Any ideas?

gunicorn does not run on windows

gunicorn does not run on Windows 10 and I can't install docker because I only have Windows 10 Home Edition and docker requires Windows 10 Pro. So I'm trying to use waitress instead of gunicorn. Do you know what the equivalent command would be to:

gunicorn -b 0.0.0.0:8000 --access-logfile - "snakeeyes.app:create_app()"

for waitress?

I'm also not sure from which directory I am supposed to be running this command from.

Add your contact info - maybe in Wiki?

I am really looking forward to the official launch. In the meantime, perhaps you could put links to:

The project page.
Your home page.
Your blog.
This repo.

Revisiting OS X Postgres permissions issue

Has anyone found a quick fix for the vboxsf mounts on OS X that stuckeyr pointed out in #18 ?

The script he linked to uses the now deprecated boot2docker to mount the share as nfs within the host vm.

Is that still the only route to go?

In the interim, just to get it running, I was just commenting out the volumes settings. Correct me if I'm wrong, but that should just disable data persistence, right?

After doing that, I'm getting the following output when trying to run db reset:

dropdb: database removal failed: ERROR:  database "exampleproject" does not exist
CREATE ROLE
Traceback (most recent call last):

...

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not translate host name "postgres" to address: nodename nor servname provided, or not known

The postgres container output is:
