How to "visit" a page without "visiting" it in Flask?

Okay, so I might just be confused as fuck or something.

When I 'visit' a page that triggers a route on my app, say like '/install', that route executes and redirects to another route, eventually generating an auth code.

Now, I want to run this route, without having to visit the page - so basically, I am trying to run this route so that I can get the auth code in the end.

Now I am calling this route from an external website. I am simply sending a GET request to a function 'load' and in that function there is another function called: get_install(), which contains the below code.

call = requests.get(url_for('install', _external = True, _scheme = "https"))

Now this code works but when I type print (request.args) nothing comes up.

So I am wondering, how do I execute the install route without visiting the {my_app_url}/install route?

Custom module not running in Notebook

Hi all,

Say I have the following in my notebook:

// some code
// bunch of other code

It runs perfectly, but if I try to create a bunchofothercode.py file and put // bunch of other code in it, and then:

// some code
import bunchofothercode

This doesn't give any errors, but it doesn't run the code.

I'm sure I am missing something, but I don't know what :)

How to combine docker instances and Apache web server for django scaling ?

I am having a doubt about scalabilty. Does configuring an Apache web server and running ,multiple instances docker multiply scalabilty ,does it increase max no requests ? What advantage do we get having cluster of computers along with web server ? What is differnce between having a load- balancer and also configuring Apache web server for having max concurrent request ?

Edit: I re frame my question,how to scale django for large web apps like 1 million users,how many simultaneous requests can a django app handle ?,how to configure my django application in such a way.

How to manually use bcrypt?

I followed the [Password management documentation](https://docs.djangoproject.com/en/2.0/topics/auth/passwords/) and managed to download the bcrypt library and use bcrypt as my password hasher. But now additionally to hashing passwords I want to use bcrypt for some other uses and create a few hashes in a python file. How can I import it and use the commands such as bcrypt.gensalt etc?

display certain number of digits

I'm using jupyter and although the following piece of code produce the proper output:

np.set_printoptions(precision=3)
print(np.array([1.123456789]))
>>> 1.123

When I use the following, as it is not a np object, it doesn't take into account the restrictions:

np.set_printoptions(precision=3)
print(1.123456789)
>>> 1.1233456789

I would like to have the same output as for np object.

Thanks in advance

Advice o two-step user registration process with SMS verification

My Django app uses a subclass of Usercreationform, with a char field for an SMS code requested via ajax. I'm using the mobile # as the username.

When submitted, if form.is\_valid and the sms code submitted is the one sent \(saved in db\), form is saved and the newly created user is logged in.

I am breaking this up into 2 steps to prevent getting flooded with malicious/frivolous sms requests. The sms field is replaced with a django\-simple\-captcha field. If form.is\_valid, a user is created with is\_active=False. The request is then redirected to a page with a one\-time url to request and submit an sms code to verify account, which flips user.is\_active to True if successful.

I'm just realizing that a vulnerability is created if someone maliciously "registers" a whole bunch of real mobile numbers without verifying, and when the real owner of one of the numbers tries to register, my form subclassed from Usercreationform would complain that an account already exists with that username.

I guess I can do something on the frontend with JS to still make it 2\-step but submit the form in one go, and if everything is valid an active user gets created, otherwise nothing happens. But does Django have anything quick and simple that solves my problem?

Also, any general advice? I thought about rate limiting with Nginx my current structure instead. But what would be a sensible rate for user sign\-up? Something like 1r/s per IP seems way too high. But if I set a rate too restrictive, I run the risk of blocking potential customers behind a NAT with a mysterious error code.

Thanks!

How to combat blog spam?

This is a bit of a meta post about r/python, rather than python itself. However, it seems to me that there is a very noticeable amount of blog spam, which I'll loosely define as having the following features:

* Poorly-written
* Unhelpful - sometimes just plain incorrect and misleading
* Heavily focused just on SEO

Have others noticed the same thing?

Can anything be done to limit the amount of blog spam? Require posts to be authorised by mods before going live? Other measures to be taken?

I just wanted to attempt to open it up for debate, so please discuss below, if this is appropriate.
