Re: do i need a custom admin app or should i just use django admin?

[James Farris]

Think of the Django Admin as a tool for developers or Database Admins.  
IMO, it should never be used by an end user.  Create views as Andreas 
mentioned and give those views permissions.

When you run the server does it give you any errors?

Re: my file uploads missing/deleted

[James Farris]

This python package may be a better choice for you, since I assume you want
all user generated content (images) to be stored in Dropbox.

This has pretty good documentation.
https://pypi.org/project/django-dropbox-storage/

If you use this package, remove the sample code I sent

Re: my file uploads missing/deleted

[James Farris]

You would add this code to the views.py file, which is where the business
logic goes.

https://docs.djangoproject.com/en/2.2/topics/http/views/

Likely would add a class with properties and methods or a definition (a
function) like below:

For example in your apps views.py file:

def connect_to_dropbox():
dbx = dropbox.Dropbox(‘your access token)
dbx.users_get_current_account()

# this stuff likely would go in a separate function
for entry in dbx.files_list_folder(‘’).entries:
print(entry.name)


At some point in your code you would call the function:
connect_to_dropbox()

Re: my file uploads missing/deleted

[James Farris]

You might try the docs from Dropbox
https://www.dropbox.com/developers/documentation/python#overview

You can checkout this project for ideas
https://github.com/singingwolfboy/django-with-dropbox

and here is documentation for django-storages
https://django-storages.readthedocs.io/en/latest/backends/dropbox.html

Unknown column 'boericke_joints.id' in 'field list

[James Farris]

If the database was originally created by Django, it would have been built with 
an ID field. Django is confused because it can’t find that field in the 
database. If you added ID to the model, did you run python manage.py 
makemigrations and then python manage.py migrate

Re: my file uploads missing/deleted

[James Farris]

He is saying these aren’t static files. It sounds like he uploads them using 
the Django admin, which of course is like an end user on a client uploading 
files to the media directory. 

Since that is the case it sounds like the Dropbox option is the best. 
Documentation was provided earlier. So being that it seems like he read through 
the documentation, my question is where is he stuck in the Dropbox 
implementation?

Module lock error when starting development server

[James Farris]

Do you have a venv running in another venv? 

You could try installing and running gdb 
https://wiki.python.org/moin/DebuggingWithGdb

It may give you more insight. But Deadlocking is essentially one python process 
clobbering another causing the app to lock up.

Re: calculate the followers difference/grow by day

[James Farris]

I think you can do something like this

stats = Statistics.objects.all().order_by('-last_update')
latest_stat = 0
for stat in stats:
print(abs(latest_stat - stat.followers))
latest_stat = stat.followers

Re: error: can not import the name 'path'

[James Farris]

As the previous reply suggests, what Django version are you using?
Using django.conf.urls is a Django 1.11 and below utility function,

Django 2.x uses this
from django.urls import path

*If you are using Django 1.x* this is what your urls.py should look like:

from django.conf.urls import urlfrom django.contrib import admin
from . import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/', views.index, name="index"),]

*If you're using Django 2.x* this is what your urls.py should look like

from django.urls import pathfrom django.contrib import admin
from . import views
urlpatterns = [
path('admin/', admin.site.urls),
path('index/', views.index, name="index"),]

Re: Starting a poll

[James Farris]

If you open the app once the server is started by going to 127.0.0.1:8000
is it loading the website or are you getting a 404 error in the browser?

I see the favicon 404 error all the time, but it doesn’t halt my site.
It’s just django looking for a favicon. That shouldn’t break anything.

Another 404 you might see is django looking for a robots.txt file. This is
normal until you have these setup.

Re:

[James Farris]

I assume you mean TemplateDoesNotExist and I also assume you have created a
templates folder in your project and have details.html in it.

If that’s the case did you check your settings.py for your template
settings?

It should look something like this.

TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates'), ], 'APP_DIRS': True,
...More code here...

Re: need help

[James Farris]

If you set DEBUG = True 
Then restart your python server then reload the page, what is the output?

It’s best to leave debug on until you have all the bugs worked out since it 
provides a lot of information that will tell you what’s happening

Are you asking where DEBUG = False is?
If so, it would be in your project folder/project name/settings.py

Re: getting error while reloading the url"http://localhost:8000/polls/".The error is given below.Please tell my why i am seeing this error?

[James Farris]

What does your urls.py look like?

According to the error it doesn’t appear that polls/ is defined in your
urls.py file

Re: ImportError : cannot import name include

[James Farris]

If you are not using a virtual env, did you install pip3? If so, since you
are using puthon3 -V to get that python version, try running
$ pip3 install django
And see if you get a different result

I think what is happening is when you run pip install it’s referencing
another python version, not python 3.

At least that is what I experienced back before I used virtual envs

Re: New project in virtual env referencing another project's default/redirected path

[James Farris]

This is where an IDE like PyCharm comes in handy. It will tell you right
away that it doesn’t recognize something and will suggest importing that
package. It does a pretty good job with its suggestions.

 Hi Doug,

 I am new to Django and i also started with MDN Locallibrary project.
 Everything went fine until Django admin site but I stuck at "Creating
 our home page
 "
 I have written the code in the suggested way only but get below error when
 try to run the project. I tried taking the urls.py code from github also
 but it gives same issue.

 Could you please help me here.

 Regards,
 Ankit


 Page not found (404)
 Request Method: GET
 Request URL: http://127.0.0.1:8000/catalog/

 Using the URLconf defined in locallibrary.urls, Django tried these URL
 patterns, in this order:

1. admin/
2. ^static\/(?P.*)$
3.

 The current path, catalog/, 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.

Re: def get_queryset(self): ^ IndentationError: unindent does not match any outer indentation level

[James Farris]

The Indentation error is related to the spaces you have when you write your
code.

Based on looking at what you copy/pasted
The indentation of your def get_queryset is different from your other
def’s.

Python is very picky of how much or how little you indent your code for
good reason.

Everything that is nested inside something else should be 4 spaces or a tab
in. For example a def should be 4 spaces in from its class, a variable
should be 4 spaces in from its def.

IndentationError: unindent does not match any outer indentation level

Re: Message from a django beginner user

[James Farris]

In addition to the Django docs, I recommend https://djangobook.com/ although 
it’s written for Django 1.11, a lot of concepts still apply. 

Another good website is https://tutorial.djangogirls.org/en/

Just to note: Django doesn’t change the settings.py file, it only
references it so it knows what configurations to load.

Re: Display Users Posts also whether it is logged in or logged out

[James Farris]

If you want to show posts, which I assume is blog posts or something (not seen 
in your code) 
You would add an additional queryset that is passed to your template

Something like

Re: Problem with debug = True/False

[James Farris]

I also recommend going through the deploy checklist. I ran into the same 
problem and then other problems after that because I didn’t follow this.

Re: integrating themes in django

[James Farris]

Unless someone knows of an easier way, you will have to do some work to get
html/css/js themes integrated as you will have to create templates for html
and a static directory for css and js.  Then hook the css and js into the
template files you create.  It's not like a Drupal or Wordpress site where
you download a theme and install it.  It will take some finessing for a
ready made website theme to be integrated into a Django project.

It sounds complex, but it really isn't that hard.

Re: Getting error in migrate

To be absolutely clear, you need to make sure if you made changes to models.py 
you need to run 
$ python manage.py makemigrations 
Then
$ python manage.py migrate

Instead of giving the answer, I suggest looking at the Traceback section you 
posted below because the answer is there. Giving you the answer will not help

Re: How can I use a variable from the instance of my data in the upload path for a FileField in my model?

[James Farris]

I did something very similar in my models.py. I think for the date you have
to get the year, month with datetime.

def get_upload_path(self, filename): return
'pictures/{0}/{1}'.format(self.user.username,
filename) pet_image = models.ImageField(upload_to=get_upload_path, blank=
True)

This add all css, js, and images to the static root folder you specified in

Re: i'm having issues displaying parent.model.childmodel_set.all on my template

[James Farris]

If you add {{ my_users }} to your template do you get any output? If not,
you’re query set has no results.

If you run these two commands from your command line, what is the output?

python -V

 My gut feeling is that this is a diskdrive/OS type issue - rather than 
 Django specific 
 
 You may have a corrupted directory - or a bad section of disk; try the 
 troubleshooting steps above first.

In Django admin I would create a group and give it permissions and add

Re: Django--Making query use part of the matching name

Try using filter(id__regex=r'\w’)

I’m not sure if this will give you the exact results your looking for, but

Re: Django--Making query use part of the matching name

I believe you want to use icontains rather than contains. It’s case 
insensitive. 

I’m not sure without using regex it’s possible to return the results based on 
any character in any order in the search string.

Re: What were your best resources in learning programming, python, ultimately django?

[James Farris]

Early on Lynda.com was my best friend for learning basics like HTML and CSS. 
Then a lot of practice. 

Later on I took a coding boot camp in my area that really accelerated my 
learning and filled in a lot of the missing pieces. It covered HTML, CSS, PHP, 
Ruby on Rails and SQL to name a few. 

The Django docs and “The Django Book” https://djangobook.com/ we’re both great 
to get me started on Django. Also Lynda.com again for python and Django.

Re: no styling

[James Farris]

Hi Paul,

Have you read this part of the docs? 
https://docs.djangoproject.com/en/2.0/howto/static-files/

You will need a static files directory and will need to tell Django where it is 
In settings.py

Re: A first time programmer

[James Farris]

No one can walk you through how to use Django in this group. That is too much 
to explain. 

I recommend choosing a plain text editor like Sublime Text or many others that 
are free in order to start working on any coding project. 

Then once you have that, read the documentation and follow this tutorial 
written by the Django developers. 

https://docs.djangoproject.com/en/2.0/intro/tutorial01/

Re: Storing lists from api into database

[James Farris]

I would use the Requests module.  It's much nicer and comes loaded with 
stuff.  It's a module used to connect to API's.  Here's the docs: 
http://docs.python-requests.org/en/master/

As far as using what you have, to save it to the database is just another 
few lines of code.
You have to import the database model

from YOUR_APP.models import tesla

Then in loop in your view just add the following to save the data to the 
database:

tesla = tesla()
tesla.webUrl = data['response']['results'][i]['webUrl]
tesla.webPublicationDat = 
data['response']['results'][i]['webPublicationDate]
tesla.save()

A few things.  It's best practice to Capitalize your models( i.e. class 
Tesla, not tesla) 
If your intention is to generate an id in the id1 field, there is no need 
to have it because Django gives you an id field automatically.

Re: A first time programmer

[James Farris]

Hi,

If you type this in your terminal, you should see Django==2.0.4 (or some 
other version)

$ pip freeze

If not, Django is not installed.

Also, what is the syntax error you are receiving?

Re: Pythonanywhere Hosting issue

[James Farris]

Where is your DNS records stored? Godaddy or pythonanywhere. It sounds like the 
dns records are coming from godaddy since that’s the page you see when you load 
the site. 

The way I was taught is you point your cname to an A record which points to the 
server where your doc root is. It sounds like the A record and/or namespace is 
pointing to godaddy. The namespace identifies where the dns records live. 

A - points to server I.e. pythonanywhere.com
CNAME - points to an alias i.e. webapp- on pythonanywhere.com

Hope that helps.

Populate a select dropdown based on queryset

[James Farris]

Hi,

I'm trying to populate a 'vaccine' dropdown based on a 'species' of a pet.  
For example, if a pet is a 'dog' I want to display vaccines for a dog 
only.  If a pet is a cat, I want to display a list of vaccines for cats 
only.

How do I do this?  I googled, but didn't come up with anything solid.

*Here is my models.py*

class Pet(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True)
name = models.CharField(max_length=100, null=True, db_index=True)
species = models.CharField(choices=SPECIES_CHOICES, null=True, 
max_length=20)

def __str__(self):
return self.name


class Vaccine(models.Model):
vacc_name = models.CharField(max_length=100)
species = models.CharField(choices=SPECIES_CHOICES, null=True, 
max_length=20)
pet = models.ManyToManyField(Pet, through='PetHasVaccine')

def __str__(self):
return self.vacc_name


class PetHasVaccine(models.Model):
pet = models.ForeignKey(Pet, on_delete=models.DO_NOTHING)
vaccine = models.ForeignKey(Vaccine, on_delete=models.DO_NOTHING)

def __str__(self):
return str(self.pet.name) + ' - ' + str(self.vaccine.vacc_name)



*Here is my views.py*


def add_vaccine(request, pet_pk):
pet = Pet.objects.get(pk=pet_pk)
if pet.user == request.user:
form = VaccineForm(request.POST or None)
if request.POST:
if form.is_valid():
return HttpResponse(form)
else:
return render(request, 'pet/vaccine_add.html', {'vacc_form': 
VaccineForm(request.POST), 'pet': pet})
else:
return render(request, 'pet/vaccine_add.html', {'vacc_form': form, 
'pet': pet})



*Here is my forms.py*


class VaccineForm(ModelForm):

class Meta:
model = PetHasVaccine
fields = '__all__'
exclude = ('pet',)
widgets = {
'date_given': DateInput(),
'date_due': DateInput(),
}

Getting complex query set with a many to many relationship in django

[James Farris]

I am trying to *get all article objects that are part of a section* in an 
edition that is in an issue. I am stumped, even after looking at the 
documentation 

 
for django 2.x

I can get all editions with all of their sections that are part of an 
issue, but I cannot figure out how to get articles that are related to a 
section per edition.

Sample code is here:
https://codeshare.io/5vXbAD

Please note I have a many to many pass through table that has extra fields 
I am trying to get.  Specifically the "order" field.
Here is a screenshot for proof of concept
https://pasteboard.co/H8N2zTt.png

If you are able to get all articles returned from the loop in the code 
linked above, I will be eternally grateful :)

results would be passed to a template.

How to install and use Django

[James Farris]

I highly recommend installing virtualenv and virtualenvwrapper. This will 
reduce the stress of creating a bunch of unnecessary modules on your computer 
and contain each project you create in a separate environment. For example you 
wouldn’t necessarily want to install Django globally but rather for a specific 
project your working on. That’s where virtualenv comes in. 

I also recommend going through the Django Book. It walks you through an app 
that uses a lot of what Django has to offer: https://djangobook.com

Also go through the Writing your first Django app in the Django docs: 
https://docs.djangoproject.com/en/2.0/intro/tutorial01/

I use PyCharm, because it has great auto complete and debugging. 

Other references mentioned above are below. 

Django apps: https://docs.djangoproject.com/en/2.0/ref/applications/
Homebrew: https://brew.sh/
Virtualenv: https://virtualenv.pypa.io/en/stable/
Virtualenvwrapper:
