In this video: https://training.talkpython.fm/player/course/python-for-entrepreneurs-build-and-launch-your-online-business/lecture/50807 at 3:10 or so, the edit cut out the part where PyCharm imports the needed method.

I'm going to try to go back and annotate the video to avoid this confusion. Sorry everyone!

This time I paid extremely careful attention to the content of the videos while following along.

In this video:
https://training.talkpython.fm/player/course/python-for-entrepreneurs-build-and-launch-your-online-business/lecture/51012

I was able to follow along and run the app, and watch the logging from sqlalchemy.

But in the next video, there is a huge leap and gap in continuity.
https://training.talkpython.fm/player/course/python-for-entrepreneurs-build-and-launch-your-online-business/lecture/51012

It was impossible to get the app to run if you followed the videos exactly in sequence. There are a bunch of missing files and code that are not mentioned up to this point.

Sure, I could jump ahead to the end and just run the code from the repo for the chapter, but that omits steps that are necessary to reach the destination.

when I try to run the following cookiecutter command:
cookiecutter https://github.com/Pylons/pyramid-cookiecutter-starter

I get the following error:

I'm using Python 3.6.3 and Mac OS High Sierra version 10.13.2. Any idea what the problem could be?

It looks like the Bower team is recommending npm or yarn for new UI projects. It would be helpful to add yarn/npm as an alternative or in place of Bower in the videos/repository.

Hi Michael,

I'm on a windows machine, running PyCharm Pro (free trial), and I created a venv that did not offer 'None' as a Template Language setting, the only options are Django and Jinja2.

I mention that in case it has to do with the error message I got when I tried to run the app.

Can you interpret the cause of the error? I'm not understanding what it wants. I was able to get the app to run using the cmd line, but love how much faster Pycharm is, just need to get it running! Thank you for your help!

Hi, getting this error below. I downloaded the repo and opened it in pycharm. Pycharm prompted me to run the setup which I did, but get this error below:

File "/home/jia/.virtualenvs/final_2_blue_yellow_app/lib/python3.5/site-packages/setuptools-39.1.0-py3.5.egg/pkg_resources/init.py", line 892, in require

pkg_resources.DistributionNotFound: The 'blue_yellow_app' distribution was not found and is required by the application

This is taken from example "04-applied-web/final_4_blue_yellow_app" and shows up in the console after attempting a valid "Register" of a new user.

This seems to be related to recent bugs reported at:

• Pylons/pyramid_debugtoolbar#319
• Pylons/pyramid_debugtoolbar#320
  The former seems similar to the problem here. The latter seems to be the root cause and a merged fix. One of the comments on the former is: "We don't recommend raising HTTPFound unless it truly is an exception..." Oh? It seems like this was fixed in pyramid-debugtoolbar 4.3? I have that version, but the problem persists.

Below is the trace I see on the console (with my home directory slightly doctored):

Hi Michael,

I'm just starting your Python for Entrepreneurs course and am enjoying it so far.

I just finished the Python language refresher game and although my code runs, it contains this message about the word 'clear'. (see below)

I tried copying your code from github into my file and the message still displays, so I don't think it's a bug in my code, but perhaps some system setting that needs changing. I'm on Windows 7 and using PyCharm.

Couldn't find the exact fix on Stackoverflow so I thought I'd ask you how to get rid of it, it's more annoying than anything. Thank you. -Ian

Hi Mike,

I'm having an issue with this video. All others are working fine except the one:
"Build web apps with Pyramid: Part 1: Template variations / inconsistencies"

Regards,

I am having a problem with PyCharm using relative imports in my template files. I have found resources that provide solutions for a Django project. I have not been able to find anything specific about Pyramid projects. It would be helpful if I could see affected css tags when highlighting in the template as I see in your videos.

Hi Michael,

I'm following along in the Cache busting lesson and I'm getting some unexpected behavior from PyCharm when I run index.pt.

In the video, you run index.pt in PyCharm and a link appears in a terminal, and when you click the link, a browser opens, displaying the minimally-styled webpage.

When I try running the file (on Windows with the free version of PyCharm), index.pt pops up as a 'Save As' download in my default browser (Chrome). (see img below)

I tried opening it after I downloaded it but Windows was confused as to which application to use. I saw your tip in the video to hit Shift + F10, but no action happens when I do that.

Any help is appreciated, thanks!

The course uses a custom @suppress decorator. Now I've learned about __autoexpose__ that is a better solution and will likely be moved into the course.

When attempting to run the project in the video, an error is reported.

I was pretty careful to make sure I have all the same files and their content to align with what's in the video, but I must have missed a critical piece.

I am working through the email module and when I subscribe to my list I see a pyramid debug toolbar message that it is squashing an exception HTTP.Found when I send POST request to /newsletter/add_subscriber from the little subscribe form.

Is this an exception we should be concerned about or is it just part of running the app in develop mode?

It seems redirect feature will always raise an exception.

base_controller.py line 23

Hi,

I had to modify the code in the static_cache.py file because the variable __full_path was giving the directory as blue_yellow_app/infrastructure. When it goes to build the cache ID here below, it looks for the relative url given in the templates as /static/**** and joins it, giving a fullname = /blue_yellow_app/infrastructure/static/*** - and the .css files are not there.

fullname = os.path.abspath(os.path.join(
__full_path, relative_file_url.lstrip('/')))

i modified the code to look for the files one more directory up where /static is by calling os.path.dirname on the __full_path variable like so:

__full_path = os.path.dirname(os.path.abspath(file))
__base_path = os.path.dirname(__full_path)

Hi,
Just thought that you may want to add the instructions how to run a CLI pyramid project in pycharm community addition. (after running the CLI commands)

In windows it was something of this sort

1. Add local virtual environment to project settings / interpreter Drive:\Full_path_to_folder\virtualenv\blueyellow\Scripts\python.exe
2. edit configuration for running project:
   2.1. Script: Drive:\Full_path_to_folder\virtualenv\blueyellow\Scripts\pserve-script.py
   2.2. Script parameters Drive:\Full_path_to_folder\blue_yellow_app\development.ini

bare domain names example.com are not supported in deployment. pull request with a fix is proposed separately.

Hi @mattmakai , have a look at

https://www.pythondeploymentexample.com/

What do you think is up with the ssl cert?

As a new python user I wouldn't know to install zsh and I'm currently not using it but even once I do install cookie cutter the 'cookiecutter https://github.com/Pylons/pyramid-cookiecutter-starter' command isn't working.

-bash: cookiecutter: command not found
If zsh is required then the course needs to be amended or notes for bash users.

When you use bower install bootstrap-css, it gives you bootstrap-css version 3.3.6. However when I tried downloading and using the startbootstrap template, the navbar collapsing wasn't working; I checked and noticed the download zipfile from bootstrap includes bootstrap-css version 3.3.7. When I dropped in 3.3.7 instead of 3.3.6 into pycharm, the nav bar started working properly. I'm not sure if there's another way to use Bower to get the latest bootstrap-css version, but thought this was an issue worth sharing. I opened an issue on the bower-bootstrap-css github on this, so hopefully they'll just fix it there.

When cloning the forked git repo to the deployment server I receive the following error:

I have been following the deployment chapter from the course and everything up to this point is working fine.

I have double checked the deployment files and they appear to be correct; and the repo has been setup with the deploy key.

In the video Mapping routes to controller actions demo, there is a file present, but it is missing in the repository. As a result it is hard to follow along. I understand it is deleted toward the end, but it would be nice to follow along.
