Re: Question about form_valid: how to automatically set multiple fields when users input data via CreateView supported form?

[Atsunori Kaneshige]

Hi, Britto,

Sorry for my late reply.
Thank you so much!
I learnt a lot.

Looks like you created a function called get_context_data and put all 
comment data from Comment database into context with key 'comments'.
You then called 'comments' in the template. Now I don't need 
reated_name='comment' in models.py

To upload images, MEDIA_URL and MEDIA_ROOT are configured in settings.py 
and urls.py
image field is added accordingly in models.py

Thank you very much!
I will keep adding features to make my first blog app!

Best regards,

Nori

 Hi, Britto,

 Wow, it's working as expected!
 Thank you so much. (*So sorry, one more question below, please find 
 it!*)

 Basically, you added blank=True for author field and article field in 
 Comment model.
 In this way, I don't need to set author/article field in 
 CommentCreateView.

 Instead, we have post function to pass around args and kwargs such as 
 pk.
 You created form.py and author and article fields will be automatically 
 selected via post function.
 I checked admin site and comments I made were successfully saved in 
 database now!

 New views.py
 
 class ArticleCommentCreateView(LoginRequiredMixin, CreateView):
 model = Comment
 template_name = 'article_comment_new.html'
 fields = ('comment',)
 # I don't need 'article' field here, because I set blank=True in 
 Comment model
 login_url = 'login'
 success_url = "/"

 def post(self, request, *args, **kwargs):
 pk = kwargs['pk']
 form = CommentForm(request.POST, pk)
 if form.is_valid():
 new_comment = form.save(commit=False)
 new_comment.author = request.user
 new_comment.article = Article.objects.get(id=pk)
 new_comment.save()
 return HttpResponseRedirect('/')

 **
 By the way, one last thing I wanted to do on top of what we did here is 
 that I wanted to display all comments associated with each article.
 I have been trying to take data from Comment database, but I am not 
 successful about it.

 I am able to take out article data by using *object_list.*
 *But I cannot do the same thing for comments.*

 I still set related_name='comment' in Comment model.
 With this related_name, *{% for comment in article.comments %} *worked 
 in previous program.
 But now, I cannot take out comment data from database.

 Sorry many questions and stealing your time.
 I really appreciate your advice.

 P.S.
 I run shell in my terminal by typing python manage.py shell.
 I did from article.models import Comment
 and I did Comment.objects.all(), then I got all comments printed in my 
 terminal.
 I read somewhere in Django docs, saying that I can implement this kind 
 of query in django program.
 But I also read that this is not best practice in Django if I remember 
 correctly.

 Sorry, I am looking forward to any advice to take out Comment data and 
 display them in the template.

 Best regards,

 Nori

 Here is article_list.html
 {% extends 'base.html' %}

 {% block title %}Articles{% endblock title %}

 {% block content %}
  * {% for article in object_list %}*
 
   
 {{ article.title }} 
 
 by {{ article.author }} |
 {{ article.date }}
   
   
 {{ article.body }}
 Edit
 Delete
   

   
* {% for comment in article.comments %} # this one doesn't work 
 now.*
   
 {{ comment.author }} 
 
 {{ comment }}

Can you try the stable/2.2.x git branch? it contains a couple of post-2.1
fixes to the reloading code which will get released as 2.2.1 in a few days
AFAIK..

Also, is the folder  where urls-py is located shared between the host and
the VM in some way? What file system type is the host using?

Re: Help, I need to convert my python code into Secure API using Django

[Chetan Ganji]

Linux is very easy to get started, as a web developer, all the code that
you write will end up on a linux server eventually.
It would be very good idea to start learning linux immediately. You will
require that skill in the near future.
None would want to pay the price of windows server when Linux is FREE ;-)

However, for the time being, please dabble with apache + modwsgi for
windows. I dont remember exact resources I used to deploy on window.
Simplest alternative is given below.
https://bitnami.com/stack/django/installer

One thing I remember is modwsgi is dependant on the python version i.e.
different python versions require modwsgi to be built for that specific
version.
Try some the ones listed in below link, if they don't work, you have to
search online for that.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#mod_wsgi

Some tuts from youtube. I havent checked them yet so do your R Follow
the steps that they have shown i the video to see if it works.

Re: More controls on createsuperuser

[nimbiotics]

Anyone capable of running the createsuperuser command on your project most 
probably has access to all and any of the project's files, specially your 
config file.

Actually this user is either a valid su or you are in serious trouble 
because the security of your server sucks or you gave access to your 
project to the wrong person.

So, no I don't think there is any point in doing so. Not because it can't 
be done but because it is both trivially useless.and uselessly trivial.

Re: Button Event

[Ahmed Ishtiaque]

Hi Mayur,

I'm not sure what you mean by "there is no javascript in django" because I
use it all the time. JS is not tied to Django in any way since its

Re: Help, I need to convert my python code into Secure API using Django

[Chetan Ganji]

Hi Vamsi,

For No 1 - You can create a REST API using django or (django + django rest
framework).
For No 2,3,4 - For production you have to user Apache + modwsgi or nginx +
gunicorn (or other wsgi compliant server for python).

I dont suggest windows for production. If you plan to use it on linux,
below is the tutorial. I have used it many times for deployments.

Help, I need to convert my python code into Secure API using Django

[Vamsi tangutoori]

Hi Everyone,
I am new to django and python programming. I developed a facial recognition 
module in python using boto3 library. Currently I sued flask to create an 
API and test in my development environment but to move it to production i 
need to use django. Can you please help or point me in the right direction 
as to how do i do the below.

1. Take my facialrecognition.py file and convert it into an API, preferably 
using django.
2. Make this API to be pointing to a specific URL(locally on a windows 
machine).
3. Deploy this code into a production machine(windows).
4. Make sure that the API starts every time the windows machine starts to 
avoid loosing service.

Things i researched so far are:
1. How to create a django project with its REST library.
2. From the articles and tutorials i found out that this is only 
development version, to deploy in production i need a production server 
like Apache etc. is this necessary?

Thanks in Advance for your help.
Vamsi.

Re: Unable to create the django_migrations table (ORA-00907: missing right parenthesis)

[tossouwisdom]

Bonjour tout le monde et merci pour vous différents retours. J'ai donc pris 
une la version 1.11 de django et 6.4.1 de cx_Oracle car ne pouvant pas 
utiliser la version 12 d'Oracle. Je travaille sur une base qui est utilisée 
en prod. Ensuite après avoir lancé la commande migrate je me suis confronté 
à un autre problème :

Hello all,

How are you deploying your Django applications with Docker?
1- Which packages, libraries are you writing into docker compose file?
2- Are you also using a virtual environment with docker?

Hi Tosin,

The assignment tag was deprecated in 1.9 and removed in 2.0.

The details for this are here:
https://docs.djangoproject.com/en/2.0/releases/1.9/#assignment-tag

Basically it has been replaced with simple_tag. You should read the docs
for that here:

Re: about abstract user

[Andréas Kühne]

Hi,

This is not a good way of building a Django user.

To your questions:
1. AbstractUser is a class that implements some of the methods / properties
that Django expects on a User model. See here :
https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#substituting-a-custom-user-model
The way this is implemented currently it is more like extending a user
model - which you can read about here:
https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#extending-the-existing-user-model
But if you want to use AbstractUser as a base class, you shouldn't extend
AbstractUser.
2. The AUTH_USER_MODEL is a setting in django that points to the current
user model. Because you can change this via the substituting link above,
you then need to set the correct user model in settings (which is set be
the setting AUTH_USER_MODEL).

I would recommend that you read about the django custom user model for
example here : https://wsvincent.com/django-custom-user-model-tutorial/
Extending the user model can be done for example here:
https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

However I would go with creating a custom user model (if this is a new
project).

Regards,

Andréas

Re: More controls on createsuperuser

[Sooraj Parakkattil]

Sometimes during development usually this particular suggestion might be
unnecessary. This might be useful in the case of production. As in if DEBUG
=True then the creation of the superuser should need approval from the
existing admins.
