Knox is an experimental language meant to help me learn Go and explore compiler design. It acts as a systems language with high-level constructs for convenience. The compiler is written in Go and generates C. It is very early in development.

QUESTION
I have two large-ish data frames I am trying to append...
In df1, I have state codes, county codes, state names (Alabama, Alaska, etc.), county names, and years from 2010:2020.
In df2, I have county names, state abbreviations (AL, AK), and data for the year 2010 (which I am trying to merge into df1. The issue lies in that without specifying the state name and simply merging df1 and df2, some of the data which I am trying to get into df1 is duplicated due to there being some counties with the same name...hence, I am trying to also join by state to prevent this, but I have state abbreviations, and state names.
Is there any way in which I can make either the state names in df1 abbreviations, or the state names in df2 full names? Please let me know! Thank you for the help.
Edit: dput(df2)

I am creating a simple registration/login app in Django Rest Framework using Rest APIs with Django Rest Knox's authentication, in which, upon registration, user will also upload a CSV File (which is an optional field).
I have a Person
Model which is an extended (derived or OneToOne
) Model of User
Model and has FileField
for the file to be uploaded.
I have two ModelSerializer
s, one is based on User
Model named MainRegisterSerializer
and serializes username
, email
and password
fields, and the other is based on Person
Model named RegisterSerializer
, which serializes FileField
and register
field (that is initialized with MainRegisterSerializer
class's constructor.
Now, in views.py

, to get the data from front that which includes username

and password
fields from User
Model, and FileField
from Person
Model.

By default jest will find any test files in your entire project. If you are building or copying files to a build/release directory, you need to do one of the following:
- exclude test files from your build pipeline, OR
- exclude your build directories from jest

I'm learning web scraping and found a fun challenge scraping a Javascript handlebars table from this page: Samsung Knox Devices
I eventually got the output I wanted, but I think it feels "hacky", so I'd appreciate any refinements to make it more elegant.
Desired output is a dataframe/csv table with columns = Device, Model_Nums, OS/Platform, Knox Version. Don't need anything else on the page, and I will split/expand and melt the Model Nums separately.
...ANSWER
Answered 2022-Feb-28 at 20:22To scrape the texts from the DEVICE and MODEL CODE column you need to create a list of the desired texts using list comprehension inducing WebDriverWait for the visibility_of_all_elements_located() and then write it into a DataFrame using Pandas and you can use the following locator strategies:

QUESTION
I was trying set up google authentication with react frontend and django rest framework backend. I set up both the frontend and backend using this two part tutorial, PART1 & PART2. When I try to login with google in the frontend I get POST http://127.0.0.1:8000/google-login/ 400 (Bad Request)
I think it's because my google api needs an access token and an authorization code to be passed. After debugging the react js, I noticed the response I get from google doesn't have an authorization code. I suspect because responseType
is permission
(by default), Source:React login props , instead of code
. I was wondering how would you change the response type in react? (I'm not even sure if this alone is the issue)
Here's my backend code

Answered 2021-Nov-04 at 23:26After investigating a bit on my end, I think I might have a solution that works for you.
I've messed with OAuth before, and it's quite tricky sometimes because it has to be robust. So a bunch of security policies usually get in the way.
I'll provide my full step-by-step, since I was able to get it working, trying my best to match what you posted.
Firstly, to have a clean slate, I went off the example code linked in the tutorials. I cloned and built the project, and did the following:
- Creating a new project on GCP
- Configured the OAuth consent screen
- I set the User type to "internal". This options may not be available if you're not using an account under GSuite (which I am). "External" should be fine though, just that "internal" is the easiest to test.
- Created a OAuth 2.0 Client
- Added
http://localhost:3000
to the "Authorized JavaScript origins" and "Authorized redirect URIs" sections
- Added
- Configured the OAuth consent screen
- Register a Django superuser
- Registered a
Site
, with value oflocalhost:8000
for both fields. - Went into the admin panel, and added a
Social Application
withClient ID
andSecret Key
as the "Client ID" and "Client Secret" from GCP, respectively. I also picked the localhost site that we added earlier and added it to the right hand box. (I leftKey
blank)
- Registered a
Example of my Application Page
- Filled in the
clientId
field inApp.js
, in the params of theGoogleLogin
component.
Here's where I ran into a bit of trouble, but this is good news as I was able to reproduce your error! Looking at the request in the network inspector, I see that for me, no body was passed, which is clearly the direct cause of the error. But looking at App#responseGoogle(response)
, it clearly should pass a token of some sort, because we see the line googleLogin(response.accessToken)
.
So what is happening is that accounts.google.com is NOT returning a proper response, so something is happening on their end, and we get an invalid response, but we fail silently because javascript is javascript.
After examining the response that Google gave back, I found this related SO post that allowed me to fix the issue, and interestingly, the solution to it was quite simple: Clear your cache. I'll be honest, I'm not exactly sure why this works, but I suspect it has something to do with the fact that development is on your local machine (localhost
/127.0.0.1
difference, perhaps?).
You can also try to access your site via incognito mode, or another browser, which also worked for me.
I have knox token set up, can I use it instead of the JWT tokens?
I don't think I have enough knowledge to properly answer this, but my preliminary research suggests no. AFAIK, you should just store the token that Google gives you, as the token itself is what you'll use to authenticate. It seems that Knox replaces Django's TokenAuthentication
, which means that Knox is in charge of generating the token. If you're offloading the login work to Google, I don't see how you could leverage something like Knox. However, I could be very wrong.
Does the
class GoogleLogin(SocialLoginView)
, take care of the steps of validating the access token and code with google and creating the user with that email in database?
I believe so. After successfully authenticating with Google (and it calls the backend endpoint correctly), it seems to create a "Social Account" model. An example of what it created for me is below. It retrieved all this information (like my name) from Google.
Example of my "Social Accounts" page
As for how to retrieve the login from the browser's local storage, I have no idea. I see no evidence of a cookie, so it must be storing it somewhere else, or you might have to set that up yourself (with React Provider
s, Service
s, or even Redux
.

I am just getting started with regular expressions (working with the stringr
package), and I have written some code that does not do exactly what I want it to do. I am working with a dataset with some very messy string data and am trying to clean it up to be used with a google maps API.
I've attached a sample of the data below.

A numbered street, such as 10th Ave

QUESTION
I have Django server which uses WebSockets to send real time updates to web clients. This is all running perfectly fine locally (with manage.py runserver
), but in production I am running into the problem that most messages are simply not sent at all. I test this by opening two browsers, making a change in one, which should then be reflected in the other browser. Like I said, this all works locally, but not in production. In production some WebSocket messages are sent by the server and received by the web client, but maybe 20% or so? The rest is just not sent at all.
