Can you configure when the server is not running?

yes

that's the sudo password for your system, not sudo for postgres

service postgresql start ┌─[amani@parrot]─[~] └──╼ $service postgresql status ● postgresql.service - PostgreSQL RDBMS Loaded: loaded (/lib/systemd/system/postgresql.service; disabled; vendor preset: enabled) Active: active (exited) since Mon 2019-05-13 23:58:54 EAT; 4s ago Process: 25265 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 25265 (code=exited, status=0/SUCCESS)

Please format the code you posted, by wrapping it in triple backticks. -> `

I think its running now. Though the output is not the same as the one am watching from the tutorial..

whats wrong with the code

from django.shortcuts import render from django.http import HttpResponse # Create your views here. def home(request): return HttpResponse('<h1>Blog Home<h1>') def about(request): return HttpResponse('<h1>Blog About<h1>')

it give an error like this Page not found (404) Request Method: GET Request URL: http://localhost:8000/blog/about Using the URLconf defined in django_project.urls, Django tried these URL patterns, in this order: admin/ blog [name='blog-home'] blog about/ [name='blog-about'] The current path, blog/about, didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

show your urls.py

from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('blog', include('blog.urls')), ]

your blog.urls

from django.urls import path from . import views urlpatterns = [ path('', views.home, name='blog-home'), path('about/', views.about, name='blog-about'), ]

from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('blog', include('blog.urls')), ]

replace path('blog' with path('blog/'

replace path('blog' with path('blog/'

Hello guys, I want to make a hotels dictionary so users can browse the hotels and see a list of hotels depending on the city that they chose and see the hotel details such as location and contact information. I need your suggestions in this app. Do I need create an app for hotels, app for the users, app for accounts? Like how many apps I need here ? I mean Django apps under my project. Hotels owners will be able to sign up and put their hotel information. Users need to sign up too. Thank you

Any suggestions?

i can tell you just 1 app. when you will be developing and you see the app is going big then just isolate some models and logic and put them in another app. it is difficult to say (else you are an expert) that my project needs how much app

Thank you very much. I just wanted suggestions because I don’t want to work on something and then realize that I’m doing it wrong. 😁

think about if u can re-use what you are trying to build for examples accounts could be an app because you could re-use it into another project with login/logout/registration etc.

yes. but sometimes you might not re-use. but the code and logic become big and complex.

guys i have made a blog with which users can create a post only if they are logged in and also added edit button for those post. But the issue is all the logged in users can edit any post.

can anyone share some bits of code to display edit button only if the author of the post is logged in ?

You should share models and views

just a min

all users can view the post , but only logged in users can edit it

all users can view the post , but only logged in users can edit it

and where's the login required in your post_edit view ?

even the template does not have any check about authenticated users , so anyone can edit posts

and where's the login required in your post_edit view ?

base.html

even the template does not have any check about authenticated users , so anyone can edit posts

can is send some screenshots ?

yup, but logout and put the url of post_edit view in your browser 😊

can is send some screenshots ?

nope, use imgur for sharing pics

go to localhost:<your-port>/post/post_edit/ after logging out or post_new

nope, use imgur for sharing pics

not post detail post edit and post add urls

not post detail post edit and post add urls

okay

not post detail post edit and post add urls

you are just showing a button in the template for add a post or edit if the user is authenticated but if u try to open those urls , you can still edit/add even if u are not authenticated

you are just showing a button in the template for add a post or edit if the user is authenticated but if u try to open those urls , you can still edit/add even if u are not authenticated

yes

yes

so use login_required decorator on top of your post_edit and post_new views

after doing that you can restrict the view to logged users

👍thanks a lot

👍thanks a lot

the second step is to make a view where author can view just his posts , so you need to filter by author

by filtering by author , you show only posts related to one author and so edit the right ones

I ll try it for sure Thanks for the help

Inside your edit button in HTML file you can use {% if post.author == request user %} <button>Edit<\button> {% endif %}

request.user

This can be used for showing or not the button, but the view keeps accessible by anyone
