Django unable to show webpage - python

1Trying to use Django 1.10 to create a file upload system (similar to this example here. My main problem is, no matter how hard I try, Django is unable to show my webpage (404 error). I have no idea why. I'm following the 1.9 example and it should be working, as far as I can tell. I've attached the error and my data tree

You need to remove the .html in your URL conf so that it becomes url(r'^upload/$', upload, name='upload'). So if your browser url is http://127.0.0.1:8000/upload/upload/ it should go to the upload view.
To display content in upload.html replace render(request, 'Final.html') with render(request, 'upload.html') in your upload view

Is there a way to remove the side navigation bar containing file names in the latest version of streamlit?

I recently upgraded streamlit to version 1.10.0. After upgradation I ran streamlit only to find that there is a side navigation bar displaying python file names present in my directory. I have attached images for the same.
import streamlit as st
import pandas as pd
from services.multiapp import MultiApp
from functools import partial
from pages import show, analysis, help, custom, download, three_d
def refresh():
pass
file = st.file_uploader('Upload CSV file',
type='csv', help="Format")
if file is not None:
# verification
# Prediction
st.button("Refresh", on_click=refresh)
data = pd.read_csv(file)
app = MultiApp()
app.add_app('Show data', partial(show.app, data))
app.add_app('Analysis', analysis.app)
app.add_app('Custom Plots', custom.app)
app.add_app('3-D Plots', partial(three_d.app, data))
app.add_app('Download', partial(download.app, data, file.name))
app.add_app('Help', help.app)
app.run()
Please help me to remove the side navigation bar.

Streamlit sidebar picks everything up that is located in the "pages" folder (see here: Blog Streamlit)
You could either rename your pages folder to something else or if you like the side bar, you can just collapse it initially:
import streamlit as st
st.set_page_config(initial_sidebar_state="collapsed")
That way the sidebar will be closed on start but can still be opened if needed.

A little late to this question, but I added the following snippet to the pages that I wanted to hide the lists on.
no_sidebar_style = """
<style>
div[data-testid="stSidebarNav"] {display: none;}
</style>
"""
st.markdown(no_sidebar_style, unsafe_allow_html=True)
This got rid of the Streamlit generated page components on the sidebar and let me keep all my other components.

Add this to all the pages you want to hide the page list from, but there should not be any ‘ul’ in your page except for the page list.
st.markdown("<style> ul {display: none;} </style>", unsafe_allow_html=True)

I'm still trying to deploy this web app and after fixing the wsgi.py not found error by putting it in the same dir as manage.py, now I have another problem where the 'api' folder is not being found, any help is appreciated!

Importing from different directories in Python

I'm trying to build a very simple Web Scraper that scrapes from popular Job Boards and posts the jobs in a simple Django website.
In my Scrapy spider, I am trying to create a Django model object for every job scraped. But I'm having trouble importing the model in my Scrapy spider file.
This is my folder structure:

What I want to do is, if I run the spider "indeed.py", I want it to be able to import the main/models.py file. How would I achieve this?
Thank you for your help! :)

]
i already create hashers.py and also the honeyword generation in honeywordgen.py . i still get this error . can someone help me ?

You have missed out the comma after your custom hasher. It should be:
'honeywordHasher.hashers.MyHoneywordHasher',
Without the comma, Python concatenates the string with the one on the next line to form 'honeywordHasher.hashers.MyHoneywordHasherdjango.contrib.auth.hashers.PBKDF2PasswordHasher', which causes the import error.
