Search functionality

Hello,

​

I am seeking an advice, ideas and best practices regarding to a search function implementation. I have a database of items that have names and descriptions and I also have a bar on the website that requests a search through the items.

​

Currently, I have it made with nltk currently, it simply tokenizes and matches against the contents of db entry (its not super accurate). I was wondering how you guys have implemented it, if you did.

​

Thanks

Edges of 3D surfaces produced using Mayavi seem "rough" or "jagged"

Hello, I'm currently trying to imitate the code done in Matlab which were used to produce these 3D surfaces (see here http://davidbrander.org/Images/index.html) on Python. I've decided to use Mayavi.

Before diving into the project, I've decided to learn Mayavi using the standard examples. Here's a well-known example of Boy's surface, which is also Mayavi's logo -- https://docs.enthought.com/mayavi/mayavi/auto/example_boy.html#example-boy.

Here's a screenshot of the surface generated by the code:

Notice that the edges aren't smooth, unlike the really nice pictures by Brander. What should I do to fix this on Mayavi?

Admin list view: a FileField is displayed as a link going nowhere

I ran into this implementing my own app but I managed to reproduce it in the official Django tutorial's project (the Polls app). If I add a FileField to a model and add the field to `list_display` on the ModelAdmin implementation, the resulting list view will display a link for the FileField's value: [screenshot](https://i.postimg.cc/tRM3PXTY/image.png) as if were an object's change link. The link obviously doesn't work and returns a

> Question with ID "sample.srt" doesn't exist. Perhaps it was deleted?

error. Using `list_display_links = None` or `list_display_links = ['question_text']` didn't change this (in the latter case, it did provide a functional link on that column). I know I can work around it using

def file_name(self, obj):
return obj.file_obj.name
file_name.short_description = 'File'

list_display = ('question_text', 'pub_date', 'was_published_recently', 'file_name')

But what am I missing here? So far the implementation of the admin has been pretty straight-forward if you understand the various points to make the changes, but this puzzles me why this would even happen out-of-the-box if it's broken out-of-the-box...

I’m trying to create a real estate app and I’m stuck between having one app for buyer and seller or creating two separate apps.

Hello, I’m new to django. I’m trying to create a real estate application where a seller can post properties and a buyer can enquire about them. A seller will also have a separate dashboard where all his listings will be and enquiries on his listings.

Both buyer and selller have a lot of common fields, right now I have a separate seller app with seller model created. I’m working on the user app with django’S built in user module so I’m not making a user model.

Should I keep it this way or combine them into one app?

Session list only holds first two items?

Hello,

​

Currently I am working on a shopping cart for my eCommerce store.

To handle my "shopping cart" I decided to use sessions.

​

I have added simple code to do this.

On a post request where "add to cart" is clicked

​

if 'cart' in session:

session\['cart'\].append("a")

else:

session\['cart'\] = \["a"\]

​

is my code.

​

Unfortunately this only works for the first two iterations. That is, when I click add to cart, once it stores session\['cart'\] = "a"

then I click it again it results in session\['cart'\] = \["a", "a"\]

​

but when I do it a third or more times, I get

session\['cart'\] = \["a", "a"\]

​

Does anybody know why my session list can only hold two items in the list?

​

Thank you.

Can someone explain why people use Anaconda for Python?

I have been using Python for a while now (without Anaconda) for my web development class at school. I noticed that a lot of people use Anaconda for Python, so I decided to see what it was. After trying it out myself it seems like a Python environment with pre-installed libraries. Why don't people just install Python and add libraries when they need them? I'm sorry if this is a silly question, but, what is the purpose of Anaconda?

Sample medium sized code bases in Python, with bugs and/or failing tests?

So, the title is pretty much what I'm looking for. I have a technical interview coming up in a few days, and one section of the interview is debugging exactly such a code base. Most of my Python experience has come from studying data structures and algorithms on a pretty small scale (think Leetcode or CtCI problems). Would anyone know if such a thing exists somewhere that I can access? It would be a Godsend for my interview prep.

[AF] I am trying to make a button that updates a variable server side.

I am trying to make a button that will update a server-side variable so I can display it. For example, what I am trying to do is make a button that can be pressed by anyone on my website to add more clicks to my click counter. Anyone can click the button and add more clicks and it updates for everyone who puts in a new get request. Anyone have ideas on how to go about this? Thanks!

Session data lost after redirect but only with iPad

My Django app integrates with GoCardless, a UK payment provider through their API. When a user sets up a new GoCardless account the process works as follows:

* My app generates a token and saves it in a session variable
* It redirects to GoCardless which captures the user's account data via 2 screens.
* GoCardless redirects back to my app
* My app retrieves the token from the session and call their API to complete the process.

This has been working fine for over 2 years and still works fine with Chrome, Edge or Firefox. But recently I started getting error reports from users. Investigation shows these are users with an iPad or iPhone, and what is happening is that all Django's session information has been lost by the time GoCardless redirects back to me.

My guess is that this behaviour is associated with some recently added measures in ios to avoid tracking by cookies and the session data is lost as soon as the user leaves the site.

Does anyone know exactly why this is happening? Can anything be done in the Django settings to avoid it?

I have sidestepped the issue for now by saving the token in a database table instead of in

Beginner question

FYI I have no previous experience in coding. Here goes my question:

My mac has both pythons installed. I want to code in sublime text. Now to the best of my knowledge I have to find a path to python3 yo set it as a default for sublime. When I run $ test -a python3 it gives me 2 paths. One is simple another one is little larger. Both of them say python3 at the end. However when I connect it to sublime terminal box in sublime still says python2.

I'm not sure if I explained it well. Hope it's clear. Has anyone experienced the same problem?
