Re: Local variable dump on exception in production environment (DEBUG=False)

[Web Architect]

Hi Simon,

Thanks for your response. 

include_html was what I needed and the stack trace in mail contained the 
variable dump.

Thanks a lot.

Hi Carsten,

Thank you!
I finally understood what's happening.
I should have added choices into each question.
Now, choice_set.all thing is working!

Thank you for your advice!

Re: PLEASE HELP! Django documentation, Writing Your First App, Part 4

[Carsten Fuchs]

Well, you're adding choices to q = Question.objects.get(pk=1).
But is this also the question you call the view with?

I suggest you add a few more print statements below your existing

print(question)

For example:

print(question.pk)
print(question.choice_set.all())

# Or, a bit more verbose, for example:
for c in question.choice_set.all():
print(c.pk, c)

# Is the following a valid PK among the choices printed above?
print(request.POST['choice'])

Best regards,
Carsten

Django timezone problem

[Mikko Meronen]

Hi,

Is there any easy way in Django to catch end user's local time when end
user access the webpage?

I have read django documentation and tried to google solutions, but I get
quite confused. Below you will find my code. In short the code should show
a story on my webpage what happened in the past on the current day. However
it doesn't take into account the endusers local time, and thus doesn't work
properly.


*Views.py*
from django.utils import timezone

t = timezone.now() *[This should somehow react to endusers local time]*
dm = t.strftime('%m-%d')
history = history.objects.filter(monthday__exact=dm)
historystory = random.sample(list(history), 1)
args = {'historystory':historystory}
return render(request, "news/home.html", args)

*home.html*
[in html I have just the basic things to show the content]



{% for x in historystory %}
 {{ x.title }} 
 {{ x.subtitle }} 
 {{ x.content }} 
{% endfor %}




*Settings.py*
LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True

You can check my webpage (http://www.topithenewsdoggy.com/) to get better
understanding what I'm doing. The part is under Additional info.

You have to add Choices for each questions you have created in database
like the process is same as you used for the questions.

 Hi Django users,

 But I have a problem in vote.
 I inserted print(question) and this is printed in detail.html
 also, question.id is also printed.

 BUT, choice part doesn't seem working.

Re: Where is the data set of the Django documents demo models

[Jason]

I'm not sure what you mean?  if you're referring to the way querysets and 
the ORM operate, there's a thorough section in the docs.  but if you're 
asking how to model data and use a db, that's out of the scope of django as 
a whole.

Hi Nitin,

Thank you for your comment.

I did  

jango-admin startproject mysite

and cd mysite, then

python manage.py runserver

and server is working, so I did

opython manage.py startapp polls

polls app was successfully created, and stopped the server because I wanted 
to user postgresql instead of the default SQLite3(?).
I did below

pg_ctl -D /user/local/var/posgres start

postgres successfully started running, then stopped

*By the way, I registered polls app in settings.py (I just copied and 
pasted part of codes from the file below)*
INSTALLED_APPS = [
'polls.apps.PollsConfig',

*Also, I followed the way to add postgres as database, I looked as Django 
docs*
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Koitaro',
'USER': '',
'PASSWORD': '',
'HOST': '',
'PORT': '',
}
}

*I did migration too, like migrate, makemigration etc, just copied and 
pasted from Django Docs*
*This is my models.py*

import datetime
from django.db import models
from django.utils import timezone

# Create your models here.


class Question(models.Model):
question_text = models.CharField(max_length=200)

field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE,

]

*When I go to admin, I added 5 or 6 questions, and successfully added in 
database.*
*the database name I made is 'Koitaro'.*
*I registered in settings.py and I have this database named as Koitaro in 
my posgresql*


question has data, but choice thing doesn't seem having any data...

I really appreciate your thoughts.

Re: Where is the data set of the Django documents demo models

Yes, it is not supposed to be a copy paste demo. You're supposed to work
along the tutorial, use the shell, and not throw in a bunch of files and
opening the browser to see if it works

Re: PLEASE HELP! Django documentation, Writing Your First App, Part 4

[Malick Cisse]

Hi, copy and paste wouldn't actually make you understand Django. Try to 
write the code yourself and you see how quickly your understanding grow.

Re: Where is the data set of the Django documents demo models

[Jason]

I feel I have to disagree, and the reason is the point of the tutorial is 
to show you the basics with the various parts of django, and you're 
creating a data set as you go along.

https://docs.djangoproject.com/en/2.1/intro/tutorial02/#playing-with-the-api  
shows you how to use the ORM to create a new question
https://docs.djangoproject.com/en/2.1/intro/tutorial02/#explore-the-free-admin-functionality
 shows 
you how to use the admin to create and edit questions
https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-your-first-django-app-part-3
 shows 
you how to make templates to list questions and show a specific question

That's all from data you're creating in the second step.

What do you feel you would get from having a data set provided as an 
example over the process above?

Re: Where is the data set of the Django documents demo models

[Fogmoon]

Thanks for your answer and advice. 

BTW, I think the data set should be somewhere because the demo is based on 
the data set. Maybe on the document author's computer. I just think 
provided the data set with the document will be more helpful for Django new 
users.  So hope the author or others can attach the data set with the demo.
