QUESTION
I am trying to merge a Qr Code onto a pdf. When I split the code into two separate scripts it works fine. I am new to phython any help is appreciated. I am running this on RHEL 7.4 in Phyton 2.7 Yes I know it's old but it is a 3rd party server and I cannot upgrade it.
...ANSWER
Answered 2021-Apr-26 at 14:26Your error is saying that your own pyqrcode instance has no create function, which it does not. Also, best not to name a class with the same name as a module
You can fix that by importing the create function

QUESTION
I am using pyqrcode. I want to save the generated QR code to s3 bucket.
...ANSWER
Answered 2020-Oct-15 at 21:09Put your image file creation in a try/except first to see if it can create the file successfully. I did similar type of thing in the past, I saved the file to /tmp and then upload it there after.
So first check to make sure that your file is created and can save out locally to the lambda, it may be due to the location. Isolate out to see if it's the file creation problem or uploading problem.
QUESTION
This python / flask script creates an svg QR code byte stream but when I try to render it using a Jinja2 template {{ qr[0] }}, it renders as text. How can I render it as an image? As you can see from the code below, I have successfully transferred the data to the client - I do not need help with that - the only issue is that the data is in the wrong format - an svg byte stream - whereas I want to display that data as an image.
For the benefit of clarification, I MUST export the qr code in the render_template because I have other variables that contribute to the qr code, which also need to be exported. Therefore, the method does not work.
Likewise, I do not want the data to be visible in the URL.
...ANSWER
Answered 2020-Aug-18 at 19:58You've to decode the byte stream before usage in the template. Further you've to use Jinja's | safe filter.

QUESTION
I am trying to generate a vCard QR code with the pyqrcode library but I cannot figure out the way to do it.
I have read their documentation 5 times and it doesn't say anything about vCard, only about URL and on the internet, I could found only about wifi. Does anybody know how can I do it?
I want to make a vCard QR code and afterward to display it on django web page.
...ANSWER
Answered 2019-Apr-28 at 03:00Let's say :
We've two libraries:
- pyqrcode : QR reader / writer
- vobject : vCard serializer / deserializer
Flow:
a. Generate a QR img from "some" web site :
web site send JSON info => get info from JSON and serialize using vobject to obtain a vcard string => pyqrcode.create(vcard string)
b. Show human redeable info from QR img :
pyqrcode read an QR img ( created from a. ) => deserialize using vobject to obtain a JSON => show info parsing JSON in the web site.
OR... after deserialize using vobject you can write a .vcard file
QUESTION
I can't wrap my head around how to dockerize existing Django app. I've read this official manual by Docker explaining how to create Django project during the creation of Docker image, but what I need is to dockerize existing project using the same method.
The main purpose of this approach is that I have no need to build docker images locally all the time, instead what I want to achieve is to push my code to a remote repository which has docker-hub watcher attached to it and as soon as the code base is updated it's being built automatically on the server.
For now my Dockerfile looks like:
...ANSWER
Answered 2017-Nov-13 at 18:14This question is too broad. What happens with the Dockerfile you've created?
You don't need docker compose unless you have multiple containers that need to interact.
Some general observations from your current Dockerfile:
- It would be better to collapse the pip install commands into a single statement. In docker, each statement creates a file system layer, and the layers in between the pip install commmands probably serve no useful purpose.
- It's better to declare dependencies in setup.py or a requirements.txt file (
pip install -r requirements.txt), with fixed version numbers (foopackage==0.0.1) to ensure a repeatable build. - I'd recommend packaging your Django app into a python package and installing it with pip (
cd /code/; pip install .) rather than directly adding the code directory. - You're missing a statement (CMD or ENTRYPOINT) to execute the app. See https://docs.docker.com/engine/reference/builder/#cmd
QUESTION
I am using pyqrcode module in python and generating QR code with it. How to put the logo in the center of that QR code.
The code looks like this
...ANSWER
Answered 2019-Oct-25 at 12:32If you use a high-redundancy algorithm (eg H), you can damage the generated QRCode up to a certain percentage. H means you can cover 30% of the data and it'll still work.
That means it's just a case of placing your image over the code. The format is up to you.
