Reverse for 'new_entry' with arguments '(1,)' not found. 1 pattern(s) tried: ['new_entry/<int:post_id/$']
I am currently working on a tutorial in the "Python Crash course" Book. The tutorial is about creating a "blog" Webapp with Django. The idea is create an app called blogs in the project and a model called BlogPost. The model should have fields like post, text and date_added. Create a superuser for the project, and use the admin site to make a couple of short posts. Make a home page that shows all posts in chronological order. Create a form for making new posts and another for editing existing posts. Fill in your forms to make sure they work. I am currently stuck at editing an existing Entry form and receive an Error, when I run http://127.0.0.1:8000/posts/1/ I have read the answers for questions similar to mine, but the solutions they propose have already been reviewed and it still gives me an error. I do not understand why. If anyone can help me I would really appreciate it. views.py from django.shortcuts import render, redirect from .models import BlogPost, Entry from .forms import BlogPostForm, EntryForm def index(request): """The home page for blog.""" return render(request, 'blogs/index.html') def posts(request): """Show all posts.""" posts = BlogPost.objects.order_by('date_added') context = {'posts': posts} return render(request, 'blogs/posts.html', … -

Possible design schema to avoid concatenating joined query results
I have a permission model in which I have Users, Groups, Resources and Entities. Each user belongs to one or many groups, and each group can access a specific set of resources and entities. To simplify, I chose to deal with resources and actions as a single string, like resourceA.create and resourceB.delete. So I came up with: class User: id = db.Column(db.Integer) name = db.Column(db.String) class Groups: id = db.Column(db.Integer) name = db.Column(db.String) class UserGroups: id = db.Column(db.Integer) group_id = db.Column(db.Integer) user_id = db.Column(db.Integer) class Permissions: id = db.Column(db.Integer) group_id = db.Column(db.Integer) resources = db.Column(JSONB) # List of strings in the format of "resource.action" entities = db.Column(JSONB) # List of strings in the format of "entity" # The permission table would be something like: "master" | ["*"] | ["*"] "admin" | ["resourceA.create", "resourceA.read", "resourceA.delete", "resourceA.update"] | ["entityC", "entityD"] "member" | ["resourceB.create", "resourceB.read", "resourceB.delete"] | ["entityA", "entityB"] This would be pretty straighforward if I had a simple relationship between users and groups, but gets messy if users <> groups is a many-to-many relationships (one user can be a part of many groups). I guess could solve this with a fairly complex query, joins users, roles, permissions, but than I would have … -
Django - Not sure why my form isn't working
I have multiple forms with large numbers of inputs. I'm not seeing any errors but nothing is showing up in my database either. I also don't really understand the whole URL path thing.
