I would start by upgrading pip (https://pypi.org/project/pip/).  Version
9.x was quite some time ago.  Also, pipenv's current version is 2020.11.15 (
https://pypi.org/project/pipenv/).

[Jorge Gimeno]

Without any more context, a Google search brought up this:

Hopefully that is helpful.

We would need the full trackback and the file where the error occurred to
be able to offer any more specific help.

Re: Was I supposed to be able to create a question on the website using 'runserver'?

[Jorge Gimeno]

That's a helper function to get the Question instances you need for
testing.  It's a way to query for those questions without repeating the
same code over and over in tests.

Re: Error on unauthorized access problem in django

[Jorge Gimeno]

django.contrib.staticfiles by design will serve static files only when
debug is set to False.  It's not designed to serve static files in a
production environment.  See here:
https://docs.djangoproject.com/en/3.0/howto/static-files/deployment/

Re: TypeError: __init__() got an unexpected keyword argument 'Null'

[Jorge Gimeno]

Similar to keys in a dictionary, keyword argument names are case
sensitive.  Try to pass in the lowercase version 'null':

Raison_Non_Delivery_cd = models.ForeignKey(Raison,
on_delete=models.CASCADE, related_name='raisonNonDelivery', null=True)

NoReverseFound is one of those exceptions that I need a mental mapping
for.  It's not necessarily easy to intuit the meaning from the name
itself.  What works for me is that Django is saying "You've given me a
named URL, and I can't find it."

In your template, there's a url tag. The first argument of a url tag is the
named url it should insert there.  You give the tag 'display_data', but
there is no urlpattern in either of your urls with the name set to
'display_data'.

In your fusioncharts/urls.py, I would add this (completely untested):

from django.urls import path
from fusioncharts import views

urlpatterns = [
> path('home/', views.home, name=''),
>
   *path('display_data//', views.display_data,
name='display_data'), # <- Added here!*

> ]


Now we have a path with the same name that your template is looking for,
you have a view it sends the data to, and you capture the variable that
will be sent to the view.

Hope this helps!

Re: PROBLEM WITH Multiple SETTINGS.PY FILE

[Jorge Gimeno]

I'm not sure why you're getting an exception.  I know the import mechanism
in Python 2 was a bit different, so I'm not sure if that's the issue or if
Django's import mechanism isn't finding your settings file.

I don't know if you have tried this, but I saw a blog post on using
multiple settings files.  Maybe it will help:
https://simpleisbetterthancomplex.com/tips/2017/07/03/django-tip-20-working-with-multiple-settings-modules.html

I hope this helps!

Re: PROBLEM WITH Multiple SETTINGS.PY FILE

[Jorge Gimeno]

It's coming from your settings file.  I would try this:

In this line here:
elif HOST == "Sai" :
from settings_dev_sai import *

I would try to make the second line:
from .settings_dev_sai import *

See if Python can find the module that way.  If Python does, then all of
the imports in that file need to be changed.

If that's not the case, then we need to see what the directory structure
looks like to figure this out.

It means there is nothing named gisproperty at django.contrib.  If you want
an intro to GIS in Django, see here:

ROOT_URLCONF is meant to tell Django where the root urls.py is.  It is
generated by manage.py startproject to point to the urls.py it creates in
settings.py.  In your case, it should point to '.urls', where
 is your main project folder.

Then, I would use an include in the root urls.py to add the pie-chart
route, similar to what you did for fusioncharts.

There's good options out there.  As with everything, there's a tradeoff to
consider.

1.  How much work do I want to put into DevOps?

2.  How much am I willing to pay to have someone else do it?

If you're willing to do the work yourself, then a self-hosted option would
be best.  DigitalOcean and Linode are two services I have used in the
past.  For enterprise level stuff, Amazon Web Services is the option I hear
most (I don't have anything with needs at this level).

If you want to pass the hard work to someone else, then a Platform as a
Service may be the way to go.  Heroku you've mentioned, PythonAnywhere has
been suggested, Divio is a new one I have heard about.

Hope this helps!

Re: Page 404 error after running Django server

[Jorge Gimeno]

I just realized that the view is returning an HttpRequest.  It should be an
HttpResponse object (and the import should be changed to bring that object
in as well).

This is related to your previous post.  The fields aren't showing up, and
they won't until they are properly defined and the database migration is
done.

To create the fields in Python models, we have to set the name of the
attributes equal to the class of the field type.  In simpler terms, using
your model class and just the name attribute:

from django.db import models


class Destination(models.Model):
name = models.CharField(max_length=100)

Try setting the rest of the attributes using the assignment operator ('='),
then run migrations again.  You should see the fields in the admin.

Re: OperationalError at /admin/login/attempt to write a readonly database

I'm not a linux expert, so other folks can feel free to correct me.

In linux, the user that creates the file in a directory they have access to
has "ownership" of the file.  With that, the user can both read and write
to the file.  All other users (except for sudo users, I believe) have
read-only access by default.

That's what's happening here.  When you ran migrations as the currently
logged in user, your user has read and write permissions.  Apache, however,
runs as a different user, so it cannot write to the database.

That answer I linked did have some things to try, in addition to a link to
more general question about permissions.  The file you would need to change
permissioins on (since you're using sqlite3, which is file based) is named
(without quotes) "db.sqlite3'.

Hope this helps!

If you're looking to use the template to generate line numbers, I would
start with the linenumbers template tag:

In Django 2.0+, path objects were introduced.  They do not use eegular
expressions like url objects did.  They use strings.  You can see examples
in the docs here:

https://docs.djangoproject.com/en/3.0/topics/http/urls/

If you want to use regular expressions still, I believe they are re-path
objects.  See the link above.

Hope this helps!

I would remove all the default=False options from your model fields in
Owner. Re-run migrations, and try to submit the form again.

For my projects, I am going to keep CSRF tokens. The time taken to put one
in a template is minimal, and I don't run the risk of turning off CSRF
somewhere and having that be the reason for an incident.

Re: Tutorial "Writing your first Django App": NoReverseMatch at /polls/ - down at the end of part 3

[Jorge Gimeno]

If settings.DEBUG == False, then you have to put the allowed addresses
in settings.ALLOWED_HOSTS.  If Debug is True, then I'm not sure what's
going on.

Re: Django Project Created in Pycharm using App Engine Does not include Django boiler files

[Jorge Gimeno]

I believe you can still install Django the old fashioned way into your
virtual environment, i.e. (with your environment active, and from the

pip install django
django-admin startproject test_project

Concuerdo con lo que indica Cosmos.  Con eso dicho, el problema, aun que
aparece en la linea 12, es en importar la clase de contexto.  En Django se
llama Context, que es una definicion de clase, y no context, que es un
modulo.  La linea 3 deberia ser:

from django.template import Template, Context

La linea 12 enconces seria ctx = Context()

Suerte!

I don't have Windows currently installed, but I have used Django on Windows
before.  What are you trying to do, and what happens?  If there's a
traceback please copy and paste into your reply, as this mailing list

To be pedantic, the object is None.  It's a known issue with Powershell on

Re: I AM getting this error plss help me

[Jorge Gimeno]

Can you try closing the powershell, running the Powershell as an admin,
then trying again?

Another option would be to try from the command terminal instead of
Powershell.

Let us know how it goes.

Re: Error while hosting on heroku

[Jorge Gimeno]

if you used --app appname, then migrations didn't run.  You can use 'heroku
run python manage.py migrate blog' (without the single quotes) to migrate
the blog app models, or 'heroku run python manage.py migrate' (again
without single quotes) to migrate all the models in the project.

Re: Beginner needs help getting templates to work - is this the right group?

[Jorge Gimeno]

I think Alvaro is on to something.  I just noticed that there ins't a
virtual enviroment active, and the traceback shows that pipenv run wasn't
used either. Can we try pipenv shell and then running python manage.py
runserver again? If you didn't install Django using pipenv install, do that
first.

Django is a framework that supports a lot of features, and that means
there's a lot of moving parts.  However, similar to driving a car, you need
to know a few things to get things working, rather than knowing the
niceties of how everything works.

To address your point about project structure, there's a lot of opinions on
this (most of them are subjective). I have a structure I use and I'm
comfortable with, but Django will support some variety in this.

Without seeing what code you have and what happens that is not expected, we
don't know where we can help.  So, to help us understand, we need to know a
few things.

1.  What steps did you take to get here?

2..  What goes wrong?  If there's a traceback, copying and pasting it is
invaluable.

3.  We may ask to see code.  Again, copying and pasting that will help us
understand what is going on.

You said that your project isn't working once you get to templates.  Is
there a book or tutorial you are following?  That might help us know where
to start.

In addition to this list, there is a forum at forum.djangoproject.com (I
follow posts in there as well).  That might be another resource for you, as
sometimes the question you have has already been answered.

There's a package you can check out called tqdm.  It's on PyPI here:
https://pypi.org/project/tqdm/. 

There's good docs there.  Integrating it I leave as an exercise to you.

 This is fixed and will be released with 3.8.2, per what I've read.  If
running 3.8.2 release candidate 2 isn't an option, is downgrading to Python
3.7 an option?

I did some experimenting in the Python shell.   What I found is this:

 jlgimeno@jlgimeno-Lenovo-G50-45  ~  python3.8
Python 3.8.1 (default, Dec 31 2019, 11:21:33)
[GCC 9.2.1 20191008] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> a = [1]
>>> b = [1,]
>>> c = [1,],
>>> a
[1]
>>> b
[1]
>>> c
([1],)

The variables a and b are both lists with a single object, but c is
different.  It is a tuple, with the first (and only) element is a list.  c
is similar to your authentication_classes variable in your view because of
that trailing comma which makes it a tuple.  As you can see in the last two
lines of your traceback, django rest framework is trying to get a list of
authenticators using a list comprehension, by calling each class that is an
element of self.authentication_classes.  It's not getting a callable back,
it's getting back a list.  Lists are not callables, and so Python raises an
exception.

To fix this, remove the trailing comma in your authentication_classes
variable like so:
authentication_classes = [TokenAuthentication,]

That should work. Hope this helped!

Errors are frustrating!  As much as we may want to, we can't help without
some further information.  Since a 404 indicates that the page cannot be
found, we need at minimum the urls.py files involved.  Also, the traceback
in the terminal would be useful.  Cut and paste, please.  This list strips
attachments.

I vaguely remember having this problem on Windows. Are you able to try to
run your project under Python 3.8 and see if that helps?

Re: Big Problem After Going Live: NoReverseMatch at /login/ Reverse for 'password_reset' not found. 'password_reset' is not a valid view function or pattern name

[Jorge Gimeno]

What I believe is going on is that Django is looking for the password reset
view at password_reset, and that url path doesn't exist anywhere in
urls.py.  I see a path named "password-reset", which won't match.

Let's try to rename that url conf to password_reset, and leave the rest
unchanged.  Does anything change?

This exception gives us information in the traceback about how to find what

Re: Django tutorial part 2: "It’s important to add __str__() methods to your models"

[Jorge Gimeno]

Hmm.  Not doing that on mine.  It is correct that __str__() is defined in
models.Model, which your models inherit from.  I don't know why it would be
considered an error.

Mark,

Try py -m pip install .  Pip isn't always on the

your system?

The exception is pretty clear here:  The string '1' is not a valid UUID
value.  Without seeing the rest of your code, it's impossible to know where
that value came from.

I believe DATABASE_URL is set on Heroku itself as a configuration
variable.  If you provision the database in Heroku, it will be set for
you.  See here:
https://devcenter.heroku.com/articles/heroku-postgresql#provisioning-heroku-postgres

Re: good day guys

[Jorge Gimeno]

By chance did you set AUTH_USER_MODEL in settings.py?  That's a requirement
if you're using a custom user model (I guessed that because your UserRole
inherits from AbstractUser). There's a good tutorial on writing a custom
user model here:  https://wsvincent.com/django-custom-user-model-tutorial/

Re: How can I host my application in web hosting?

[Jorge Gimeno]

Deb,

Digital Ocean will allow you to run what you can install.  If you can get
it on the server, you can use it.

Heroku and Python Anywhere do have specific services that are available.
You can check out their documentation to see what they are.

I don't know much about AWS, so that I will not be able to answer.

Hope it helps!

Re: TypeError: api_view() takes from 0 to 1 positional arguments but 2 were given

[Jorge Gimeno]

It looks like the call to @api_view should be like this:

@api_view(['GET', 'POST'])

In other words, pass in a single list of the permitted HTTP methods. Docs
here: https://www.django-rest-framework.org/api-guide/views/#api_view

Re: app urls

[Jorge Gimeno]

Hello,

With the information we have here it's very difficult to suggest anything.
I assume this is a web project. Are you using a framework? Which one? How
do you render the html pages? What have you tried so far?

All questions which will help us help you.

Re: AttributeError: cffi library '_constant_time' has no function, constant or global variable named '__spec__'

[Jorge Gimeno]

Searches to both of your error messages suggested a mismatch in .so
objects. I would uninstall and reinstall Django and see if that helps.

Re: a variable is not defined

[Jorge Gimeno]

wd,

The problem here is that when you're creating the context, the name
'result' is not defined. When the get_queryset() method returns, the result
name goes out of scope.  My guess that's why you're getting a NameError.

If that's not it, I would suggest cutting and pasting the traceback and
showing us the actual code (with line numbers if you have them). It will
help us diagnose the problem.

Can you please post the traceback?  Copy and paste, please. Without that we
won't know where the exception is raised.

Would you be able to copy and paste the stack trace here? Without that,
it's really hard to see where this exception is coming from.

Re: How to proceed with my Pull request?

[Jorge Gimeno]

Mahdi,

You may be waiting for a bit.  As a general statement, package and
framework maintainers are volunteers and tend to work on their projects
around the other priorities in their lives. It's normal for a bit of a
delay in getting something accepted.  You can certainly contact the
maintainer, but I wouldn't expect a response right away.

Re: problems with mysql client

Rob,

On the off chance you haven't seen it, I found a Stack Overflow question on
this:
https://stackoverflow.com/questions/25459386/mac-os-x-environmenterror-mysql-config-not-found.
Unfortunately, I don't know Mac OS all that well to offer more help than
that.

Re: django-admin ...command error

[Jorge Gimeno]

This is a good case to use manage.py instead, as manage.py sets
DJANGO_SETTINGS_MODULE.  See here:
https://docs.djangoproject.com/en/2.2/ref/django-admin/.

 I'm not aware of any way to disable this mechanism but testing against
 the
 exact HTML returned from a view seems fragile.

 I suggest you use assertContains[1] (with or without html=True) and
 assertTemplateUsed[2] instead.

Re: problem in activating virtual environment in Django with ". \Scripts\activate" command

[Jorge Gimeno]

I assume that's in Windows Powershell. I think it's .\Scripts\activate.bat

I would also check to ensure that the Scripts folder exists in your current
directory.

To edit files you need a text editor of some sort. Notepad or Word are not
very useful. A good one I have seen people use is Mu, located at
https://codewith.mu. Notepad++ is another good option for Windows.

Scott,

Once you cursor disappears, your server is running and listening for
requests. Open a browser and point it at http://127.0.0.1:8000 and see what
