How to store data on database after user login using social API, like facebook
I'm working on a react-native app using django as backend. The backend has a User table that extends AbstractBaseUser, and I want to store the data of social logged users inside this table. Now let's say I'm using facebook and google as social-auth API, when I get the data on the fronted, profile_id and email (for instance in the facebook case), what field do I have to use as password? I mean you'll say it's not necessary because the authentication occurs through the facebook server, but the "social_login/" endpoint is accessible without any permissions so anyone can make a request using facebook user email and its profile_id, as I saw it's possible to get it thought html inspector. So what do I have to use as unique and secure identifier when the user login-in using social API for the second time? Do I have to create a token/hash based on profile_id and email? Please don't suggest me django-social-auth or something similar, they don't fit my needs because of the high levels of customization I need. Thank you -

Broken pipe while parsing CSV file multiple times using pandas
I have a search bar which takes city name as input. A GET API is build on django, which takes the user input and search for the input in the CSV file. For example: If user types "mum". The API takes this "mum" as input and searches for all city names starting with "mum" in the available CSV file. The search is performed everytime user enters a character. But after some time I get an error, as the API is called on every character input by the user: Broken pipe from ('127.0.0.1', 63842) I am using pandas for performing city search ### check for cities list from csv file def checkForCities(request): cities_list = [] cnt = 0 for index, row in city_dataFrame.iterrows(): if cnt >= 6: break if row["cityName"].startswith(request): print(row["cityName"]) cities_list.append({"city_name":row["cityName"], "city_code":row["id"]}) cnt += 1 return cities_list -

Django: How to extract text from doc and docx files and then pass it to template to display it in a separate div that can be later on styled?
I am working on a Final Project for CS50W and I want a small app that allows users to upload their 'scripts' - files that are either .doc or .docx. These files are then saved in a separate folder and its url is saved in a models field. I want to create a separate view for displaying the contents of these files, that I can then later on style separately (changing background and text colors, size, etc.), so I want to extract the text from these files and pass it on to my template. But when I do that with open file function, I get FileNotFoundError - which I presume is because this file is not .txt file. What would be the best way to achieve this? Here's the relevant part of my code: class Script(models.Model): ... upload = models.FileField("Select your script", upload_to="scripts/%Y/%m/%D/", validators=[FileExtensionValidator(allowed_extensions=['doc', 'docx'])]) ... def read(request, script_id): script = Script.objects.get(pk=script_id) file = open(script.upload.url, 'r') content = file.read() file.close() return render(request, 'astator/read.html', { 'script':script, 'content':content, }) Maybe there's also a better way to achieve this with JS? Anyhow, thanks in advance for your help! -
Django Test key association

How to solve list complex issue in python?
Have the function testfunction(num) take the num parameter being passed and perform the following steps. First take all the single digits of the input number (which will always be a positive integer greater than 1) and add each of them into a list. Then take the input number and multiply it by any one of its own integers, then take this new number and append each of the digits onto the original list. Continue this process until an adjacent pair of the same number appears in the list. Your program should return the least number of multiplications it took to find an adjacent pair of duplicate numbers. For example: if num is 134 then first append each of the integers into a list: [1, 3, 4]. Now if we take 134 and multiply it by 3 (which is one of its own integers), we get 402. Now if we append each of these new integers to the list, we get: [1, 3, 4, 4, 0, 2]. We found an adjacent pair of duplicate numbers, namely 4 and 4. So for this input your program should return 1 because it only took 1 multiplication to find this pair. Another example: if … -

how do I consume django api from react frontend
I'm new to React, I've written a Django API endpoint to perform some kind of sync. I want this API to be called from a React page, on clicking a TextLink - say Sync Now, how I should go about doing it? Based on the response from the API(200 or 400/500), I want to display Sync failed, on successful sync, I want to show Sync Now again, but with another text Last Sync Time: DateTime(for this I've added a key in my Django model), how can I use this as well. Also, I've a followup, say instead of Sync Now and Synced we have another state Syncing, which is there until a success or failure is returned, Is polling from the server is a good option, or is there any other way. I know of websockets but not sure which can be used efficiently. I've been stuck here from 3 days with no real progress. Anything will help. Thanks in advance. -
