How does Django handle file upload

If a client uploads a file to my Django server and subsequently in the view I upload that file to some other server, does Django handle this asynchronously? Suppose I’m using Gunicorn. What I’m asking is, while I’m uploading the file to the other server, is my gunicorn worker free to handle a different request while the file is being uploaded?

The reason I’m asking is if this is the case, then I’m going to find an alternate solution as I don’t want my server to become unresponsive if all the workers are busy uploading a file.

As an extension question, is the behaviour Django exhibits common? I.e. if I was using Node can I expect the same behaviour?

Can someone better explain flask blueprints to me?

I am curious about the use case for blueprints, I am semi familiar with flask basics but I need to learn about blue prints and all the documentation/tutorials I've viewed still seem cryptic about the fundamental issue blueprints resolve.

I feel like I'm understanding limit_choices_to wrong

Hello. I've read the documentation page on it and searched Google/SO for answers but I just can't seem to wrap my head around it.

I've got the following schema:

class MainModel(models.Model):
pass

class Criteria(models.Model):
parent = models.ForeignKey(MainModel, on_delete=models.CASCADE)

class ChildModel(models.Model):
parent = models.ForeignKey(MainModel, on_delete=models.CASCADE)



What I want to do is have a many-to-many relationship between ChildModel and Criteria, and limit the options of the Criteria to the MainModel's criteria set.

So basically the following:

class ChildModel(models.Model):
parent = models.ForeignKey(MainModel, on_delete=models.CASCADE)
criterias = models.ManyToManyField('Criteria', limit_choices_to=parent.criteria_set.all())
// I want to do this ^^^ (criterias isnt the plural form but bear with me)

But I keep getting errors about the parent not having an attribute "criteria_set" (which I assume would be the way to get the parent's list of criteria)

Am I going about this the wrong way? How would I make it work?

If something's unclear in my question please

Hitting back button on Django form wizard causes page expired error(and nukes all data), particularly on Internet Explorer?

Hey all, creating multi-step forms using django form-wizard and on firefox and chrome it seems to work fine hitting the back and forwards buttons(both using provided buttons and with browser). But using IE, when hitting the browser back button, it said 'Page Expired' and all the data previously entered in the forms was lost.

Any idea how to prevent this or what is going wrong? Thanks guys.

Customizing the user registration flow using django rest-auth for social authentication

I am stuck with a situation and can't seem to find a good solution on how to proceed further. Currently, I am able to authenticate a user using google. So the person is able to create an account and logs in. However, in doing so, the user already has a randomly generated username and all. I want to create a situation where when a user is authenticated via google, they are redirected to a registration form where they can provide a username of their own choice. What is the most efficient way of going about this? My main goal is to ensure that the blacklisted usernames which we can provide in the allauth settings is also utilized when a user provides their own username.

“NameError: global name” Question

Im new to python and flask, however I am not new to programming languages by any means.

I am building a simple web app and something caught my attention that I found kinda strange. (From my point of view)

I added url_for in an html template and it works, however I forgot to import it into my .py script and got an error(as I should)

From my understanding Jinja2 is responsible for the HTML part. Is it safe to say that Jinja2 has all modules imported as part of it base and always readily accessible, therefore never needing “import”?

Need help with AJAX calls, and redirect

Hey everyone,

This is my first time using flask and I am looking for some help. The goal of the application is to display most frequent words in lyrics. I have written a class that cleans the data, and pushes dictionary into json file. I currently have the main page (base.html) which accepts artist name, song name, and onclick it generates data into json file. I use chartJS which generates a pie chart for me on a chart.html page, using the data from the json file. I am forced to render\_template to see the chart. My question is, how can I make an ajax request so that on click I can generate the graph in my base.html page after the click?

Thank you.

Need help with Flask API regarding security and JWT

Hello fellows,

&#x200B;

Long story short, I am developing my API using Flask and I want to secure it against replay attacks and other MITM things, as well as random people querying the address.

&#x200B;

So I have seen that JWT could be the answer (using secure HTTP of course to prevent those nice MITM) but there is something I definitely can't understand.

&#x200B;

Once we auth ourself, the server gives us a token, that we are supposed to **store** and send at every request to prove the server we are the real auth person.

But by doing so, considering we send the token using HTTPs so saying like 'okay it's supposed to be enough secure (https) and anyway we won't be querying the api in vulnerable environnement such as public wifi etc..' and considering the token will be linked to a socket right ? Like we link the TOKEN to A USER, for A SESSION therefor the TOKEN is only good for our actual socket (IP/PORT couple), correct me if i'm wrong.

&#x200B;

So this ensure only *US* at this exact moment can use this token, and not some guy from idk where since that, even if he gets it, he will not have the
