Django admin site URL routing issues/inconsistencies
I am working on a website on Django 1.10, and I am trying to set up my admin site so the URL is at "/pcari/admin" instead of "/admin" Here is my root urls.py: from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ # Admin site url(r'^admin/', admin.site.urls), # Regular site url(r'^pcari/', include('pcari.urls')), ] Here is my app urls.py: from django.conf.urls import url from django.contrib import admin from . import views app_name = 'pcari' urlpatterns = [ # Admin site url(r'^admin/', admin.site.urls), # User-facing views url(r'^$', views.index, name='index'), ... ] This setup technically works in that if I visit "127.0.0.1:8000/pcari/admin" I get the admin site, but I also get the admin site if I visit "127.0.0.1:8000/admin", which is something I do not want. However, if I remove the "url(r'^admin/', admin.site.urls)," line from the root urls.py file, I get a weird error when I try to access "127.0.0.1:8000/pcari/admin": NoReverseMatch at /pcari/admin/ u'admin' is not a registered namespace Request Method: GET Request URL: http://127.0.0.1:8000/pcari/admin/ Django Version: 1.10.5 Exception Type: NoReverseMatch Exception Value: -

Django Model Password Field Security
I am creating a sports app which allows users to create their own leagues and invite their friends to play. Ideally I would like to password protect the league. This is the table as it currently stands: class StraightRedPersonalLeague(models.Model): seasonid = models.IntegerField(primary_key = True) personalleaguelongname = models.CharField(max_length=36) personalleagueshortname = models.CharField(max_length=24) leaguepassword = ???? leagueispublic = models.NullBooleanField(null=True) soccerseason = models.ForeignKey('straightred.StraightredSeason', db_column='soccerseasonid', related_name='personalleague_seasonUserSelection') class Meta: managed = True db_table = 'straightred_personalleague' I have had a search on stackoverflow and found the following: How to create Password Field in Model django The answer wasn't accepted but has had some upvotes. Is it safe to store the password as a charfield? If so I assume the forms.PasswordInput is the part that is doing all the "magic" regards security. Any advice on this security issue would be appreciated. -

Python; Django adding characters to path name causing OS error 22
I've been trying to get django to render a template I created. At first it said that the template does not exist, however once I fixed the error it is now adding characters to the path and not finding the template because of that. The path should be: C:\\Users\\ABC\\Desktop\\science_crowd\\Lightweight_Django\\placeholder\\home.html However the error says that it cannot find: C:\\Users\\Benjamin\\Desktop\\science_crowd\\Lightweight_Django\\placeholder\\:\\home.html It added a colon and another backslash for no reason.

Django: have admin take image file but store it as a base64 string
I was tasked with creating an admin view such that a user could input an image file, which however would be stored as a base64 string as a model field rather than exist in a static files dir on our server. I'm unclear on how exactly this process would be done, should I be intercepting the POST request from the admin view and pre-processing it to be stored in the field? Should I be overwriting the save method of the base form? I'm a little confused by the different methods and have been unable to produce a working result. Here's my setup: models.py from django.db import models class Product(models.Model): organization = models.ForeignKey(Organization) name = models.CharField(max_length=50) logo = models.TextField() admin.py from django.contrib import admin from .models import Product class ProductAdmin(admin.ModelAdmin): exclude = ('logo',) admin.site.register(Product, ProductAdmin) misc.py #how i'd process an image? from PIL import Image from base64 import b64encode def image_to_b64(image_file): imgdata = Image(image_file) encoded = b64encode(open(imgdata, 'rb')) return encoded -
