Display users bookings when they are logged in - python

I am hoping someone can help me with something, I am new to Django and am currently putting together a restaurant booking system application. I have a lot of what I want to do done already but what I now want is for all a users bookings to appear in a "My Bookings" page when they are logged into their accounts. I want to give people the option to edit or cancel bookings if needed.
Can anyone guide me in the right direction in terms of making just the users bookings appear when they log in?
Thanks

You can check if the user is authenticated in your view with if request.user.is_authenticated (docs here), then if so you retrieve all of their bookings and display the bookings page to them. If not, you can redirect to the login page for example, or just the home page or whathever.

How to redirect a user to a different page if he's logging in for the first time after registration in django?

I have created a Getting Started page to which I have to send the users if they are logging in for the first time after registration.
I also referred to this question but didn't understand anything
If not I have to redirect them to the Home page.
I have set the LOGIN_REDIRECT_URL to 'home' in settings.py
I have not tried anything yet because I have no idea about how I should do it. Please assume a simple html for both the pages with an <h1> tag containing their respective names
There are multiple ways to achieve this, and this are three that I usually do:
you can put additional field in user model, for example seen_getting_started that is boolean and during processing of home template in views.py you can check for this field and redirect accordingly to getting started page. I have an option that user needs to select his language and date formats, so if it not changed and stored in his profile than "select language and date format" page pops out
you could also check his creation time, if it is created in last 10 minutes it is safe to assume that the user is new, but there might be some issues with that if you use for example mail check during registration
if you are using mail check during registration, than you need to lend user on "email confirmed" page that could also lead to your getting started page.
Hope it helps. Sure that other options might work too.

Problems limiting editors to their own content in Wagtail admin

Users that have been assigned to a group with 'add' permissions are able to access, copy, move and add pages created by other users via the admin search or by directly entering the correct path in the browser.
The goal is to prevent users from seeing anything the other users are doing. I had thought it was pretty much implemented.
My page tree looks like this:
Home > Persons > Person Profile > Person Story
Users sign up for an account and are automatically assigned to a custom 'Authors' group. This group has 'add' and 'publish' permissions on the Persons page. The user is responsible for any number of people on their team. With this setup they are able to add a Profile page for each member of their team. Then multiple stories may be added for each person with a profile. Now each Person has subpages of Stories linked to their profile.
I have the page explorer set so users only see their pages:
#hooks.register('construct_explorer_page_queryset')
def show_authors_only_their_articles(parent_page, pages, request):
user_group = request.user.groups.filter(name='Authors').exists()
if user_group:
pages = pages.filter(owner=request.user)
return pages
The image chooser also only displays images uploaded by the user:
#hooks.register('construct_image_chooser_queryset')
def filter_images_by_user(images, request):
images = images.filter(uploaded_by_user=request.user)
return images
And page summary items show only what belongs to the user using similar code.
But during what I thought was going to be final testing, I discovered that a search done using the admin search leads to a list of all available Person Profile and Person Story pages with those search terms. For example if they search for 'John', all Profile and Story page are returned for John. Users may then click on John's Profile page. Once arriving on John's profile page in the explorer they are able to add Stories to John's profile, copy, move or unpublish it! They can do the same with John's stories, minus adding a subpage.
This is a game changer and won't work for us.
I've looked around and see what might be several solutions:
1) Create a similar setup using ModelAdmin but I think I'm going to have the same problem. When searching users will still be able to find and manipulate forbidden content.
2) Create a unique user group for each user as recommended in this post: Wagtail per page user permission
In the second method, after the user is created I would need to programmatically:
1) Create a new user group just for them, maybe using their username.
2) Assign them to the new user group
3) Create a new 'Person' page specific to them and grant them 'add' and 'publish' permissions to it.
The last step because it seems that if I assign them all to the same Person page, they will still be able to add pages to other users Profiles regardless of being in a different user group, since all those different user groups will still have add access to the same Person page.
Ultimately I need to block each user off from what the other users are doing. Your thoughts are much appreciated. It's been years since I've done any programming and I'm still catching up. In the meantime I'm going to start seeing I can come up with.
I think we are pretty close. The system works and flows so well!
I finally figure this one out by searching for instances of GroupPagePermission and GroupCollectionPermission in the Wagtail core package. Was able to piece it together looking at how they did it.
In the models.py of an app I have called 'users' I implemented the django-allauth user_sign_up #receiver. As soon as the user is successfully signed up it runs the below code:
from django.contrib.auth.models import Group, Permission
from django.dispatch import receiver
from allauth.account.signals import user_signed_up
from wagtail.core.models import Page, GroupPagePermission, GroupCollectionPermission, Collection
from article.models import PersonIndexPage
#receiver(user_signed_up)
def create_user_group_and_pages(sender, **kwargs):
"""
When a new user signs up create a unique group and page for them.
Assign it the appropriate permission for admin, page and collection access.
"""
# Grab the new user
user = kwargs['user']
# Create a group object that matches their username
new_group, created = Group.objects.get_or_create(name=user.username)
# Add the new group to the database
user.groups.add(new_group)
# Create new permission to access the wagtail admin
access_admin = Permission.objects.get(codename='access_admin')
# Add the permission to the group
new_group.permissions.add(access_admin)
# Now start creating page access
# First find the homepage
home = Page.objects.get(slug='home').specific
# Create unique PersonIndexPage for the user
person_index_page = PersonIndexPage(title=user.username)
# Add PersonIndexPage to homepage as a child
home.add_child(instance=person_index_page)
# Save new page as first revision
person_index_page.save_revision()
# Create new add GroupPagePermission
GroupPagePermission.objects.create(
group=new_group,
page=person_index_page,
permission_type='add'
)
# Create new GroupCollectionPermission for Profile Images collection
GroupCollectionPermission.objects.create(
group=new_group,
collection=Collection.objects.get(name='Images'),
permission=Permission.objects.get(codename='add_image')
)
Now when a creates a new account a new Index page is created for them that has a unique group created that gives them access to only that Index page and it's child pages. Effectively blocking them from access to any other content on the site. They can still see results to other pages in the admin search but don't have permission to do anything with those results.
Users can log in, create profiles for each person and then as many stories as they want for each person.

Check whether user is in django_db or no

I have the django model called "create-chat" and there I write names of people I want to see in a group chat.
So. I created the model, but I don't know how to make a condition whether user is in django_db or no, if so then I want to show them the button "join chat"
And after clicking the button he will be transferred to the url sitename.com/lobby/1
Now I have the view that shows the page /lobby/any_number
First of all I'd to block these pages from users and only if the user is in django_db
He is able to visit the page Lobby/1
ONLY THE lobby/1 not lobby/2
I don't ask you to do it, I just want you to explain me how to do it, or maybe advice me some articles about my problem.

..1). How to block all users for visiting this url sitename.com/1234 <- here goes any number u d liked. ( 4 characters )
So now I blocked all the users for visiting this page, and how now make it visible for a certain users/user?
I am assuming you are storing the information in User object.
usr = User.objects.get(username = whateveristheusername)
if usr is not None:
#User Exist. Click to join chat
else:
#Create User or any other viable functionality

Django Block URL by Username

Excuse me if I'm not very direct about what I'm talking about or need, I'm fairly new to django/python and am still in the process of understanding things.
I am creating a webapp with Django where a user will sign up, log in, create a new entry, save it, and view/edit it. Think of it as a personal diary that should be only accessible to the user who wrote it.
I've gotten pretty far in this and am using filtering in the ListView, but someone could easily use url manipulation to find other users entries.
Such that User A posts entry 4 at site.com/entry/4 and then user B is able to type that in and see the entry.
How can I go about restricting the url to only the user who posted it?
Thanks for any help, and again sorry if I'm not giving enough information or I'm not clear on what I am talking about!

Custom user dashboard in django

I have a system that has two types of users with different privileges, the first user is the admin who can access all objects from the database, the second one is a dealer who can only view information pertaining to them alone.(There are many dealers)
This is how the system iworks: the admin creates a coupon code and issues it to a person (already done) then that person goes to a dealer who is supposed to check if that coupon code exists.
when a dealer logs in he is supposed to be redirected to a dashboard that has the number of items he has sold and to whom. To sell a new item he needs to check if that coupon code exists and if it does then access a form to fill in the item details(I have a model for issued_items)
How would I implement a custom admin page for the dealer without affecting the admin dashboard.
I created a dealer with super-admin and changed his permissions so that he is only able to change specific models, problem is, the models appear with all objects in that model even the ones by other dealers.
I have thought(not tried yet) of creating a view,and a template and redirect login but if i do this then i override the admin
(not so sure)Probably create a new app for the dealer???????
This sounds like a situation where you want the functionality to be loosely coupled to prevent headaches down the road, so I'd go with option 3. Leave the admin for the admins and create a new dealer app for the dealers to go to, with a regular view/model/template that they'll be required to login to see.
I wasn't able to elaborate my question coz am a django newbie, but after a week of trying a lot of different things I found a way out. For the dealers and other non staff users I created a dashboard and also overiding the registration to suit my project.
Its now working fine.
