Re: Password reset to Gmail addresses fails

[Julio Biason]

Hi Alastair,

Just one question: are you using Gmail SMTP to send those messages or are you 
using your own/a third party?

Because Google could’ve marked your domain/server as spam and it is simply 
deleting all messages incoming from it (we had a similar problem a few days 
ago). If that’s the case, you need to contact the GMail team to ask what 
happened (I don’t have their contact ‘cause it was someone else here that 
solved that problem).

Re: Django 2.0 and MySql

[Julio Biason]

Are you sure the socket is being created on /tmp? Because that's what the
error is pointing our: You said Django should communicate with MySQL though
a socket file in /tmp called "mysql.sock", but there was some problem with
it. You should probably check your MySQL config file (/etc/my.cnf) to
assure the socket is being created there.

(On my local install, the socket is in /var/lib/mysql, so you probably just
update your settings).

Re: why is a text not displayed?

[Julio Biason]

Hello,

Did you remembered to include this urls.py in the project urls.py? This
looks like your app internal URLs, but you still need to tell the whole
project that it should include these URLs into it (with, maybe, a prefix).

Re: 'module' object has no attribute 'lru_cache'

Hi Etienne,

Python 2.x will not receive any updates (security or otherwise) starting in 
2020. Many projects are dropping python 2 support right now to allow people to 
have enough time to port their codebases to python 3.

OK, I've read the INSTALL file and noticed that Django dropped support
for Python 2.7.

Any reasons for dropping support for Python 2.7 in the first place ?

Re: how to install django on cpanel

[Julio Biason]

Hi Sakkhar,

Django can "run" in any directory. You need to install it somewhere on your
system (we use /usr/local/ here) and then wrap the code around a
WSGI exposer (like uwsgi or gunicorn). Then you "plug" your webserver to
the wsgi exposer via socket or http port.

It's not like any PHP-like frameworks, which you give the files directly to
the webserver and it does whatever it is needed (unless you're using
mod_wsgi, which was deprecated years ago towards the use of uwsgi/gunicorn.

Re: 'str' object has no attribute 'tzinfo'

[Julio Biason]

It looks like you're trying to localize a string, which is not a datetime
object and, thus, doesn't have a tzinfo property.

You'll have to convert your string to a datetime before trying to localize
it.

Re: Django Admin Form clean method override only working for one exception

Hi Dean,

You forgot to call the form clean method (the first line after your `def
clean` should be `super().clean()` as shown in the documentation:
https://docs.djangoproject.com/en/2.0/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other

Re: Scope of Django

[Julio Biason]

Hi Sidharth,

What do you mean by "scope"? Django is the backend and templating engine
(in the backend, not frontend like React/Vue/Preact). You can basically
write the whole "store data" part in Django, with the presentation on top
of it and add some interaction with the user with JavaScript (manually).

About documentation, if you never used Django before, I'd suggestion going
through the project tutorials (https://docs.djangoproject.com/en/2.0/intro/)
before anything.

Re: How do you check if a template is included into another?

[Julio Biason]

Hi Luna,

Why not do something like:

Have a base template that you will use for the basic editing, let's call it
`base_content_edit.html`:

{% extends whatever-you-use-as-base-template %}

{% block editor %}

{% endblock %}


and then, when you need a rich editor, you have a new template, say
`rich_content_edit.html`:

{% extend "base_content_edit" %}

{% block editor %}

{% endblock %}


Django templates are more based on the building on top of previous content
than including bits and pieces (although you can do that with no issues).

Re: urlopen error [Errno 110] Connection timed out

Hello,

Where does this happen? Do you do urlopen somewhere? (IIRC, changing Django
settings doesn't affect internal Python objects).

urllib.request has a timeout, it's the second parameter after the data:
https://docs.python.org/3/library/urllib.request.html?highlight=urllib#urllib.request.urlopen

But you shouldn't do anything long while answering a request. You should
probalby use something like Celery to retrieve information in the
background, freeing the request (and later show the proper response).

Re: HTML video seek problem in django

[Julio Biason]

Hi Manjunatha,

Django just serves the content, it doesn't handle how it will be played. It
could be a problem with your player, or some JS error -- in other words,
nothing to do with Django itself.

Re: How do I exactly change from SQLite to MySQL ?

[Julio Biason]

Hi Daniel,

Well, in simple terms, all you need to do is change the DATABASE setting in
your settings (here
https://www.coderedcorp.com/blog/django-settings-for-multiple-environments/
is an example of way to keep two different configurations, so you can have
a production setting pointing to MySQL while keeping your dev setting using
SQLite). You may need to create the user and a database for it, but that's
more of a MySQL-specific question than Django.

If you want to migrate your data from SQLite to MySQL, you can use
`dumpdata` to "export" the data from your dev enviroment and `loaddata` to
load it back to the production data. Both are part of the default
manage.py: https://docs.djangoproject.com/en/2.0/ref/django-admin/#dumpdata

Re: Django escapes a string partially

[Julio Biason]

Hi,

You should wrap your  `data-content={{ v.error_msg }}` in quotes, like
this: `data-content="{{ v.error_msg }}"`.

Otherwise you'll generate the template as `data-content='NoneType' object
has not attribute "rfind"`, which is a valid HTML (data-content will have
the string 'NoneType' and the node will have a bunch of tags that it
doesn't know what to do with it, so they just sit there: "object", "has",
"not", "attribute" and ""rfind"".)

Re: chemistry character set

[Julio Biason]

Hi Mike,

One thing that occurs me is that you can override the model save() to
update another field -- one that the user doesn't have access. On that
function, you will write a new field, say `sortable_name` in which you'll
transfor the chemical name into something that will appear in the proper
order, like converting alphas to A, betas to B, etc.

When you request the list of chemicals by name order, you actually use the
`sortable_name` field, which will have all the conversions in place.

Re: When do I need a new app within the site?

[Julio Biason]

Hi Andreas,

My rule of thumb is "does this works without the other?" Do your customer
app works without the booking app? Then they are two different apps, with
the second using the first as dependency.

But, then again, I had some people suggesting this wasn't good enough (for
deployment reasons, IIRC). I still use on my personal projects, though.

Re: Fetching next and/or prior objects given an arbitrary ordering

[Julio Biason]

Hi Bernd,

Well, the thing with `get()` is that it will return only one object. What
you're looking for is `filter()`.

Say, you want all the things that have an ID after a certain value. So you
get `list_of_things = Things.objects.filter(pk__gte=...)`. Now it'll return
the list, with all elements after the one you asked.

If you want the previous and next, you can do `list_of_previous =
Things.objects.filter(pk__lt=...).limit(1)` and `list_of_next =
Things.objects.filter(pk__gt).limit(1)`.

Or something like that ;P

Re: Why doesn't Django support managing Raw SQL changes using migration system like models

[Julio Biason]

Hi Cmp,

Well, Django has to be database agnostic for things to work with any
database. If raw sql is allowed, how do you can be sure it will work with
any database?

So far, you mentioned a bunch of PostreSQL things. But what if, tomorrow,
some higher ups decided that support is required and buy Oracle (because
higher ups usually aren't that smart). How things will work? How do you
make sure your raw SQL commands will work? (IIRC, there are differences in
SQL/DML between Oracle and MySQL).

The biggest problem I see is that you're using triggers. Django knows
nothing about them and since you're giving the database control to Django
(via its migrations and querysets), you should relegate all the things to
Django. And yes, there are drawbacks on that too, but still, everything
should be one single place -- and if you need other systems to add data to
your database, you should provide them with an API instead of letting them
add directly to the database.

The biggest problem I see on your solution, is that your giving powers over
your data to two different things -- Django and the database via triggers
-- and that's the first step into mess.

PS: 76 migrations is still nothing. I worked with databases with 150+
migrations, and nobody cared about what the migrations did, because the
models -- in their current, up-to-date form -- is the canonical
representation of the data. All those 150+ migrations were just the way to
reach the current state.

Re: How to access the key attributes of a model

[Julio Biason]

Hi Alberto,

I'm guessing `def blog(request):` is actually `blog_category_posts`, right?
Because you have `` on your URL, our view will receive it as another
parameter, after request. So it should be `def
blog_category_posts(requests, slug):` and then you can get the slug, filter
the posts and return them to the template.

Re: How can i use google finance client in django?

[Julio Biason]

Sorry, Rakibul, but your question is too broad — there is no way to tell you 
something because we don’t know what you’re trying to achieve.

For example:

Are you looking for a Python client for Google Finance? Did you found a library 
for that already? Do you know how to use it? What exactly it will do along with 
your Django project? How do you plan to integrate with Django? Will the user 
fill a form and then you’ll retrieve the information?

There are too many questions about your question to actually give you a proper 
answer.

Re: Finding a decent ordering widget ...

[Julio Biason]

Hi Bernd,

A bit of this "k anbd drag lines up and down to reposition them" is done by
jQuery UI, in its "Draggable" functionality:
https://jqueryui.com/draggable/#sortable

Not sure if that helps, though, 'cause you could provide functionality to
reorder using plain JS, just reordering divs around moving the DOM around.

Kinda hard to help you here, because there is a lot of information lacking.
Like, do you see any errors on your logs? Are you running in dev

a webserver (nginx) in front of it? Are you using
wsgi/gunicorn/any-other-wsgi-server? Do you see anything weird in their

Re: Infinite scrolling, Ajax, Phone or PC?

[Julio Biason]

Hi Jamaldin,

Yeah, there is nothing to do with Django, except for a part in the infinite
scrolling.

For infinite scrolling, you'll keep loading more data from the server and
adding it to the DOM when the page position reaches a certain point. Both
of those can be done with jQuery, for example, but you'll need to write
both the checker for position, loading more data and appending to the DOM
using JavaScript. The only difference is that instead of loading all the
page, you'll return only your list, either as a JSON to be "templated" by
JavaScript or returning the piece of HTML you want to add (basically, your
template won't need to `{% extend "base.html" %}`, so to say.)

Going through pages without reloading is, again, a job for JavaScript. You
basically do the same thing you did above, but instead of appending more
stuff to the DOM, you replace it.

For buttons, you can check the user agent (which you can get from
`request.meta['USER-AGENT']` on your views). But you'll need a bunch of
list of browsers and it's not really reliable (people can replace the user
agent at free will, with extensions). One solution would use the viewport
size (the area available for the browser to render) and do that directly in
JS or event CSS -- check Bootstrap "hide-xs" and the likes.

But, again, your questions are more towards JavaScript than Django.

Re: Display Many to Many Field in Django admin site

[Julio Biason]

It seems your `get_ingredients()` is expecting the Product itself and
another object (for some reason).

Have you tried to remove `obj` from the parameters and use `self` in that
function?

Re: new Feature: yay or neigh?

[Julio Biason]

My 2 cents:

1.  Django )and it's template system) runs on server. When I'll the serve not 
have a connection? If the sever doesn't have a connection, it will not sis 
anyway.

2.  What you want is probably develop a PWA with offline support. This is kinda 
built in in most browse using webworkers.

Neigh. Think about what you're proposing here:

> {% if request.connection:"http://www.somesite/service"; %}

So on the incoming browser request object you instantiate a connection from
your server to some site. This by no means ensures that the browser can
connect to that service.
There's also no way to "tell the browser to check availability to that site",
because once the request object is created in Django the browser has already
sent the request - it's not two-way communication.

This should be handled in javascript and Django cannot do anything for you
here as it's not part of the problem.

Re: Help: 'django.utils.six.moves' is not a package

[Julio Biason]

Six is self-contained it does look anywhere, it has its own list of "how it was 
before and how it is now".

In the case of moves, it has conditions of "module urlparse is urlparse in 
python 2 and urllib.parse in python 3" and then sets its own move module to 
point to one of those, based on python version.

It's weird that it can find six, but not the "moves" module. Have you tried 
deleting your virtual end and creating it again, with the new versions?

Hi Prakash,

Do you need to answer the PDF directly? I mean, can't you just use the API
to async-ly create the PDFs (using Celery, for example) and just return a
jobId of sorts? The use will, then, make calls to check the jobid status;
when the PDF is done, the job is changed to complete and you let the user
use another URL to download said PDF.

Hey Aayush,

Can you past the full error? It's kinda hard to see what's wrong with just
that description.

Aside from that, you can:

- Make sure you have your virtualenv up.
- Check the library is really installed (you can run `pip freeze` to see
which libraries you have installed in the virtualenv)
- Check the name; sometimes, the library name does not reflect the import
names.

option on the nginx document configuration that you an point to drop a
prefix -- in this case, the "mysite/" prefix. If you don't use it, Django
will receive the whole path, "/mysite/admin/login" and won't find it in its
routes.

I'm 60% sure it is something like this :p

Re: Django

[Julio Biason]

Hey Uobodomavin,

You could, in theory, use one Python, but with pure Django, you'll, at some
point, use HTML. MDN has a series of articles about HTML, which you'll see
is not that hard: https://developer.mozilla.org/en-US/docs/Web/HTML

When I mentioned pure Django, I meant that you could build a pure API,
returning JSON instead of HTML and avoiding the whole thing. It would
require someone else to write some application (or HTML page with
JavaScript) to make use of this API. If you plan to go this way, I'd
suggest getting a look at DjangoRestFramework, which is a framework on top
of Django to help build APIs: http://www.django-rest-framework.org/

Re: main page have stopped work after creating poll app

[Julio Biason]

Hi Dmitry,

Define "the main address stop working"? Do you mean it won't accept any
other requests?

You should probably check the command line where you started "manage.py
runserver". It should display a backtrace pointing to anything that went
wrong.

Re: ValueError at /polls/1/vote/

[Julio Biason]

View require that you return an HttpResponse object. Your function does not
(it probably even lacks a "return").

You need to return the response back in the view.

Re: Good afternoon, I need help to generate a PDF of my models in DJANGO

[Julio Biason]

"pruebapdf() missing 1 required positional argument: 'DesdeJango'"

Your view have an additional parameter, which is not used by views; views
always receive the "request" and then the list of parameters in your URL
definition (which does not have any parameters). So you need to remove it
from the function and actually import the class from your models.

Re: Django Model

[Julio Biason]

Hi,

If I got this right, what you want to do is save the "domainwhois" with the
expiration date of the result of the whois.whois function.

Unfortunately, things don't work in class level like this, because things
are static here: whois.whois will be run one single time, not on every
object. For that, you'll need to change something in the instance.
Fortunately, Django allows access to things in the instance with ``save``:

def save(self, *args, **kwargs):
   details = whois.whois(self.domainname)
   self.domainwhois = details.expiration_date
   super().save(*args, **kwargs)

("details" and "w" can be removed from the model itself, as they are
variables used only for retriving this information). Have a look how models
work here: https://docs.djangoproject.com/en/2.0/topics/db/models/

Re: Call to method that takes in a request

[Julio Biason]

Hi Yufenyuy,

You just instantiate the object and call the function. Something like

created_object = MyModel(field='some_value')
view = MyView()
view.get(request, created_object.pk)

If you want to create a request object, you can use RequestFactory:

Re: Some problems with running django

[Julio Biason]

Hi,

UnicodeDecodeErrors are quite common in Python 2, when you add an UTF8
character and the system is not set up for it (usually, you need to start
your code with `# encoding: utf-8`).

But the fact that this seems to affect socket is weird as heck. I'd check
anything in mytestsite/settings.py to make sure there isn't an UTF8 string
in anything related to server name (things like DATABASE, in which you
define the host for your database and the like).

Re: Upload video with automatically created thumbnail in Django 2

[Julio Biason]

Hello,

Another solution is to use `ffmpeg`. There is an option to extract (even
multiple) screencaps from a video (sorry, can't remember the proper option
for this).

And, as Daniel pointed, this is very heavy operation, so either you'll need
a heck of a server (with plenty CPU and fast disks) OR use something to
process things asynchronously, like Celery.

Re: Some problems with running django

[Julio Biason]

Hi,

I took a longer look at the error and it seems the error raised when the
server was starting up. The code tries to figure out your machine name -- a
thing that's stored, on Linux systems, on /etc/hostname and on OS X on
Settings -> Sharing -- and *that* name has special characters (I'd guess it
could be something like "曹逍遙's computer").

I don't have enough knowledge about Windows to know where you could change
that.

Re: How to execute a python(selenium) script on clicking run button in the template view. Django

[Julio Biason]

Hi Dimple,

Your `url` is invalid. Views are exposed to the world via urls; in that,
you define which URL will call which view.

If you're running Django on your machine, your URL should probably start
with 'http://localhost:8000/the/url/for/your/view' -- although the `http`
can be omitted, in which case the browser will use the current schema and
`://localhost` can also be omitted, in which case the browser will request
from the current server.

Re: button not responding when click but when press return key than works

[Julio Biason]

Hi Asif,

Are you sure you don't have any JS capturing the submit press and doing
`preventDefault()`? That would prevent the button from sending the form.

On Firefox, if you inspect the button, if it shows an "EV" near it, it
means there is something capturing the button events -- and `click` could
be one of those events, with the preventDefault().

Re: Django 1.11 Serving Large files for download ??

[Julio Biason]

Hi Gokul,

Well, since this is for intranet, you may be lucky.

For large downloads, you can put your facing server (nginx, apache) to
point directly to the media directory. For example, if your media files are
being stored on `/srv/myserver/media`, and have an URL of `/media`, you
could add a location of `/media` pointing directly to the file system (your
`/srv/myserver/media`). This way, Django won't get in the way and the whole
process of sending a large file will be the facing server problem -- and
they are better optimized for this.

The same thing goes for simultaneous requests: usually, the facing server
will launch more than one socket to the underlying service to retrieve the
information, so you end up with more "Djangos" running. One example is
that, if you use uwsgi with nginx, you can set up the number of threads
directly on uwsgi and it and nginx will take care of answering multiple
requests.

Re: Regarding an issue

[Julio Biason]

Hi Mayank,

You tried to access "/"; there is no url associated with this path, so it's
a 404. The only valid URLs are `/admin` and `/music`.

If you want to see something when accessing `/`, you need to create a view
for it and associate it in your `urls.py`.

Re: How to fill latitude and longitude values from an existing location field in Django+Python?

[Julio Biason]

Hi Prateek.

You're using Google Maps for the lat/long, right?

In this case, I'd suggest that, on the function you receive the data and
update the field, you also make a request to some URL to update the
lat/long of the current displayed object.

Re: How to run python script by clicking a HTML button?

[Julio Biason]

Hi Subhendu,

To make this all work, you'll need to do this:

1. Create a Django app
2. Add some URL to a view (any view)
3. Inside the view, run your script.
4. Change the for on the "action" to point to the URL in point 2.

You may want to read the Django Tutorial[1] to grasp who those things are
implemented and connect to each other.

Re: Newbie : Object copy - weird error :-)

[Julio Biason]

Hi Mikael,

The problem is happening because of this: __init__() takes from 1 to 2
positional arguments but 11 were given

On your new __init__(), you added just 2 parameters: `self` and `source`.
But you overwrote the default `models.Model` init, which receives way more
parameters (the original signature for this function is `__init__(self,
*args, **kwargs)`).

What are you actually trying to achieve with this?

Re: django

[Julio Biason]

Hi Musonda,

Django, yes; React, not so much.

Your question was a bit too vague and seemed more focused on the second.
Surely, when you get a better grasp of what Django is and what React is and
how they work together and have a question about the first, you can feel
free to send the question here :)

Re: Django split screen

[Julio Biason]

Hi Gerald,

You can't "split" the screen because Django is simply a way to retrieve
data from a database and send HTML to the browser.

You can, however, load the history and create a form and send both to the
template, which will display both side by side (or one on to the top of the
other, or whatever).

All you have to do is create a view that loads the history and create a
form object and send both to a template that knows how to display both.

Re: custom command

[Julio Biason]

Hi Dp,

Basically, you'll have to:

1. Add the command; the documentation explains quite well how to make a new
command:
https://docs.djangoproject.com/en/2.0/howto/custom-management-commands/

2. In that command, you'll have to read a directory. That's pure python and
you could use something like walk
https://docs.python.org/3/library/os.html?highlight=os#os.walk, although
there are other commands. Check the `os` and `os.path` modules.

3. Reading a JSON is easy peasy with the JSON module:
https://docs.python.org/3/library/json.html?highlight=json#module-json

4. And to add the values in PostgreSQL, you'll need to have your model
defined (https://docs.djangoproject.com/en/2.0/topics/db/models/) and, with
that, you just create records and `.save()` them.

Re: Django with Celery

[Julio Biason]

Hi Satyam,

Well, Celery is used for background tasks, like running requests to other
services out of the response loop and such. Your question is confusing
'cause forms are used to validate user input and, well, there is no user in
a background task.

What you can do is have a normal form attached to a view and, if the form
`.is_valid()`, you call the celery function to do the whole processing of
the registration form. Just be sure that, if your registration takes less
than a second, it is not worth running in a background task.

Re: error in coding

[Julio Biason]

Hi Rohit,

The problem is that you have `urlpatterns = ` (an assignment without value)
which is invalid Python code. Either you need to finish the line (add the
value that should be assigned to urlpatterns) or add a "\" to mark that the
line continues in the line below. (As a last resort, you can remove the
file _if you're not using it_, so Django won't try to import it and
generate the error).

Re: Oracle Connection Problem

Hi Razibul,

Have you tried to add the host and port? IIRC, the default port is 1521 and
you need to fill the host value, otherwise the driver won't know where to

Also, are you getting any specific errors?

Re: how to find activities dues for today and tommorow

[Julio Biason]

Hi Deepak,

You could set up another model to track when something should be done to
the tree; something like this:

class Tree(models.Model):
...
planted_date = models.DateField()

class Reminder(models.Model):
tree = models.ForeignKey(tree)
when = models.DateField()
what = models.CharField()
done = models.BooleanField()

So, when you create a tree, you get the current date and create the entries
on the Reminder model. Somewhere, you can get the list of reminders with
something like

to_do = Reminder.object.filter(Q(tree=tree_in_view) &
Q(when_lte=datetime.datetime.today()) & Q(done_ne=True))

And throw this in the view -- it basically says "give me all the reminders
for the tree I'm looking at in this point (say, you have a page for each
tree, so this is the tree id), in which the reminder is from a date equal
or before today (in case you don't want to show reminders for dates in the
future) and which are not done (which you should also provide a way so the
user can mark the reminder as "done" and not be bothered with it again).

You can find more information about the Q here:
https://docs.djangoproject.com/en/2.0/topics/db/queries/#complex-lookups-with-q-objects

Re: avoiding import-time queries

[Julio Biason]

Hi Clarvierplayer,

Dunno if that's a best practice, but I'd add a module in the same app with
functions to retrieve the information and use cache (
https://docs.djangoproject.com/en/2.0/topics/cache/#basic-usage) copiously.
So, instead of loading the values at start up time, the values would be
filled only after the first time it was requested.

Re: JSON serializable error

[Julio Biason]

Hi Anusha,

It seems you're trying to generate a JSON of some object/dictionary with a
Datetime in it. Datetimes are not serializable 'cause there is no date/time
representation in JSON (maybe epoch, but that's not the default).

Re: New member: Germano Carella. I need help with django, limit_choices_to and admin interface

[Julio Biason]

Hi Germano,

When you use "ManyToMany", you're saying "any book can have any chapter and
vice versa". That's obviously what you don't want. What you want is "A book
has a closed set of chapters". This is done by thinking a bit on the other
way with Django: Instead of saying "There is a list of chapters of this
book", you say "The chapter belongs to a single book" with a foreign key:

class Book(models.Model):
   title = models.CharField(max_length=250)

class Chapters(models.Model):
   title = models.CharField(max_length=250)
   text = models.TextField()
   book = models.ForeignKey(Book)

Now a chapter can belong only to a book.

Re: django

Hi Vasu,

manage.py should be created when you run "django-admin startproject

manage.py exists. That's where you should run the runserver command.

Re: Error binding parameter 0 - probably unsupported type

Hi Ruban,

Well, what's the type of `name`? That's what the error is saying: You're
passing a type that SQLite doesn't understand properly.

Also, why are you not using models to do that for you?

Re: Error binding parameter 0 - probably unsupported type

[Julio Biason]

Hey Ruban,

I'd suggest taking a look at the second part of the Django Tutorial:
https://docs.djangoproject.com/en/2.1/intro/tutorial02/

It explains how models work and how they interact with the database --
which is basically what you're trying to do.

Re: App Registeries not ready

[Julio Biason]

Hi Vikrant,

Is that the code of your models.py? 'Cause you have mixed the model
definition with model usage in the same file and that won't work -- you'll
get the message you're getting, about the models not being loaded yet,
'cause Django just read the model definition, but hasn't set up the
database yet.

If that's the case, you need to mode the `newartist` and everything else to
a view to actually do that or call it in the shell.

Re: DEBUG=False but still "Starting development server" ?!

Hi Richard,

No, that just suppresses the DEBUG messages, either in logs as in views.

To have a production server, you need to deploy with wsgi:

Re: Trouble installing Django

[Julio Biason]

Hi Phil,

This happens because you're trying to install Django system-wide and that
operation requires root (superuser) access.

The best way to install Django is to first create a virtualenv. That will
isolate the install directory from the system, so you can freely install
and uninstall any libraries without interfering with the system.

You can find more information here:
https://docs.python.org/3/library/venv.html

Re: saleor error NoReverseMatch at /en/

[Julio Biason]

Hey Tim,

Are you sure your view is defined with spaces in the urls.py? Shouldn't it
be {% url 'manifest' %} instead, with no spaces around the name?

Re: Trying to build a cart using django cart. "" error unhashable type dict ""

[Julio Biason]

Hi Carl,

The problem seems to be the use of `get_template`:
https://docs.djangoproject.com/en/2.1/topics/templates/#usage

The second parameter (the one you're using a dict) is not the values to
pass to the template, but the name of the template engine to be used.

I'd suggest using `render` (
https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/#render)
instead, which is more common than trying to get a template from a specific
loader.

Re: Django Admin Multiple Models and Dropdown list

[Julio Biason]

Hey Mab,

You probably need to replace you `__init__` to `__str__`. They are two
different things.
