do lots of projects and refer to the documentation when you need to
understand concepts in detail. Here is my private channel where I upload
django premium resources with ton of projects. here is the invite link if
you want to avoid the frustration of finding organized tutorials and hands
on to try. https://t.me/+VXTu7RXQ47VlM2Q0

Hello,

At the beginning i read much tutorials about function based django. It 
is on beginning a little bit easier because you understand how a 
list-, create-/update- and deleteview works. For little project this 
approach is fine. I waste with function based aproach too much time 
because i extend my own project after and after and then when for 
example i find a mistake in one listview most other listviewa from 
another models i must fix. So it is hugh amount of bugfixes.


Then i learn class based approach this i a little bit harder because 
you don't know which classes exists and what of this classes what 
makes. It exists in Internet one website where you find perfectly what 
classes exists and much classes have comments what class does. Since i 
use class based views i am very happy.


For a newbie, the learning curve should be as shallow as possible - "a 
little bit harder" might be too much.


BTW ... https://spookylukey.github.io/django-views-the-right-way/



On beginning i have for every listview and for every form a own 
template. Also i find same problem like in function based approach... 
Often i want to extend all of listview Templates with same feature and 
then i fix muuuch templates. Then i build me self for list-, create-, 
updateview one template where i can insert every model. Since that i

I learn how i can make own widgets.

I learn how i can makes my own filter/tags for templates.

I disagree mike with his tip to take django documentation because this 
manual is very nice when you search for a specific thing. But for 
learning as beginner this is not right approach.


I give you know my tip: learn short how you writes function based 
listview/deleteview/createview and updateview then when you know how 
it works don't waste time to go deeper in function based. Learn 
instant usage of classes based which class, method exists and what it 
makes and how you override this methods... there exists in internet 
much tutorials also in class based views


When you know this writes me then i give you more tipps

Last thing there exists a Webpage for django simple is better then

Welcome!

There would be no better way to start than working through the
tutorial in the docs, step by step ...

https://docs.djangoproject.com/en/4.2/

Afterwards, you should decide/specify your own project and when
the spec is more or less settled you should set it up as a fresh
project and make it happen.

The critical part of learning Django is the specification of what
you want. Personally, I keep the (excellent) docs permanently open
in my browser so I can research how to achieve what I want to happen.

You will discover that Django takes a couple of different paths
and you need to choose. Both are valid but I chose functional
views rather than class-based views.

My reasons were that functional views seem simpler and allowed me
absolute flexibility. I felt that class-based views while
brilliant were more difficult for me. YMMV.

Also, Django now allows async programming. That's a bit too
advanced for me - at least until it becomes necessary.

Good luck

Hello,

At the beginning i read much tutorials about function based django. It is
on beginning a little bit easier because you understand how a list-,
create-/update- and deleteview works. For little project this approach is
fine. I waste with function based aproach too much time because i extend my
own project after and after and then when for example i find a mistake in
one listview most other listviewa from another models i must fix. So it is
hugh amount of bugfixes.

Then i learn class based approach this i a little bit harder because you

Road Map for a newbie

[Tesfaye Yimam]

Hello all,

This is my second day of learning Django. I am comfortable with python (the 
basics and the OOP).
I wanted to have some guidance from this community to learn Djanog by 
taking small steps in a consistent way. 
Any one who has a road-map, especially if you tried it and worked for you,  
that will greatly help me in the learning process of Django. So, please 
drop me a message here. 
I'm happy to be here.

Hmm, when I remove the raise CommandError statement and replace it with

This helps me to point further studies. Thx!

Re: testing newbie - help requested: app works, tests give errors

['Bob Aalsma' via Django users]

Ah, yes, thanks.

I hesitate to comment on "If I understood the error right." ;)

Umm, my problem here is that I think I'm using the exact same *code* 
"manually" without errors. 
I think I'm also using the same *values* for the manual and test runs.
So I don't understand the reason for the differences in output.

testing newbie - help requested: app works, tests give errors

['Bob Aalsma' via Django users]

I'm trying to test a django-admin command and don't understand why the 
tests give errors on the code while the code works as expected.

I'm under the impression that the *raise CommandError* is ignored by the 
test, but don't understand why this would be.

Please help.

Running the code shows:

(.venv) werker@Werkers-Mac-mini domain_reader % python3 manage.py 
populate_source 0

*CommandError: Alleen hele getallen > 0 toegestaan*

(.venv) werker@Werkers-Mac-mini domain_reader % python3 manage.py 
populate_source 1

*Teksten zijn gegenereerd voor tekstlengte 1*

(.venv) werker@Werkers-Mac-mini domain_reader % python3 manage.py 
populate_source 1

*CommandError: Teksten voor nummer 1 zijn al eerder gegenereerd*

(.venv) werker@Werkers-Mac-mini domain_reader % python3 manage.py 
populate_source 7

*CommandError: Opgegeven sleutel 7 niet gevonden*

Running the tests shows

(.venv) werker@Werkers-Mac-mini domain_reader % python3 manage.py test 
tests.test_sources_app_command_populate

Found 3 test(s).

Creating test database for alias 'default'...

It's easy if you get the Python basics first. 
Suggest having a good grasp of Python basic concepts then you jump to 
learning Django. 
There's a lot of things Django can offer, you just need to understand them

Pycharm is a good option if you want to login to your VPS by ssh, but still 
it is in beta mode.
When it comes to deploy the django site, it's little bit tricky.

You can use external proxy parser like gunicorn or uWSGI and use them with 
Apache or nginx.

I want to start a project by using Django. I originally make use of hosting 
service for my project. When I setup the django, it seems some installation 
errors.

Are there any simple setup procedures for hosting services? I can use SSH 
to login the hosting server. Also, are there any good python editor which 
can remotely connect the hosting server? Please give me advice. Thank you.

Newbie question

[Moose Smith]

I have a table which holds simple data like addresses. Created a form which 
displays the records in the form and allows the user to select a record 
"address" to edit. 

I want this edit function to be generic so it will work on any table 
without me having to define fields etc... and using  ModelForm I 
accomplished by goal. 

Django creates a form and using instance='myrecord' it even populated the 
fields in the form with the record I want to edit. I can edit my fields  
and now it is time to save the changes back to the database.

I found a .save() method for 
# Create a form to edit an existing Article, but use
# POST data to populate the form.
>>> a = Article.objects.get(pk=1)
>>> f = ArticleForm(request.POST, instance=a) >>> f.save()

My question is this:
The .save method discuss in the Django Documentation above is a method of 
ModelForm but I have rendered my form and when I hit the SUBMIT button the 
edited fields are returned in a WSGI type object which does not have a save 
method.

I can use the POST data and pass the PK and so on, and update the record 
manually with some code. BUT WHAT is the use of a .SAVE method on a 
ModelForm. In order to edit the form I need to RENDER it right?

Is there a way to return the ModelForm object with the edited fields and 
then save back to the database?

Thanks 

Moose

It shouldn't. Note that env='DATABASE_URL' is entirely redundant and can be 
omitted.

In any case, check the source code for dj_database_url.config to troubleshoot 
this, but ENGINE definitely isn't needed here. As you'll see from the source, 
the url scheme determines the engine used.

Did you validate that DATABASE_URL is set correctly in the container 
environment?
I suspect this may be the issue here, although the docker-compose.yml looks 
fine.

Looks good, but to be certain jump into your container (exec or run) and verify 
that the DATABASE_URL is set correctly. It should be.


2. Does the below formatting look correct to you from my settings.py? I am 
running into issues with the env var DATABASE_URL and getting this error:  
Environment variable "{}" not set'

DATABASES = {

default="postgres://postgres@db/postgres", conn_max_age=1800),
'ENGINE': 'django.db.backends.postgresql',
}

There was a mistake in my previous response, so looks like that led you astray.

First, omit "ENGINE" here - unnecessary as postgres (or postgresql) scheme in 
the URL will drive that.

Second, you don't need to specify "DATABASE_URL" directly, that is the default 
variable used if you don't override it, or you can specify 'DATABASE_URL' 
there, or use env='DATABASE_URL'. Your choice.

If you do extract the url prior calling .config(), then use the  default= 
keyword, even though DATABASE_URL will override it. If you pass a positional 
argument to .config it will be used as the environment variable, not the value. 
If you have an already extracted value, then alternatively you can use .parse() 
instead of .config() which takes the url as the first positional arg.

dj_database_url is a pretty simple single module package. Check out the source 
code, it isn't too hard to comprehend.

DATABASES = {
'default': dj_database_url.config(conn_max_age=1800)
}

should do the trick on heroku.

3. I am also getting this error when running locally. Do you have any advice 
for troubleshooting?

I think this is the fallout from above, passing the url as the first positional

Hi David,

Thanks for the feedback!

I'm checking out dj_database_url and have a few follow up questions I was
hoping you (or someone) could help me with.

1. Since this app is dockerized, I have my existing env vars in my
docker-compose-prod.yml file. Is that where I should list DATABASE_URL?
Like:






*db:image: postgres:11volumes:  -
postgres_data:/var/lib/postgresql/data/environment:-
DATABASE_URL=postgresql://:@:/
- *2. Does the below formatting look correct to you from my settings.py? I
am running into issues with the env var DATABASE_URL and getting this
error:  Environment variable "{}" not set'





*DATABASES = {'default': dj_database_url.config(env("DATABASE_URL"),
default="postgres://postgres@db/postgres", conn_max_age=1800),'ENGINE':
'django.db.backends.postgresql',}*
3. I am also getting this error when running locally. Do you have any
advice for troubleshooting?

Re: Newbie looking for some help with Postgres <> Django connection

[David Nugent]

It's been a while since I used heroku, but iirc it just uses a formatted pg url.

Install the module dj-database-url and use this in settings instead of the 
default DATABASES layout, something like:

DATABASES = {
'default': dj_database_url.config(os.environ['DATABASE_URL'], 
conn_max_age=1800)
}

Then set DATABASE_URL in the heroku (and your development) environment. This 
setting will be of the form:


DATABASE_URL=postgresql://:@:/

Again, its been a while but I also seem to recall that the DATABASE_URL is 
provided to your app automagically(?) a part of the provisioning so does not 
need to be explicitly set there.  Using the dj_database_url module in your 
settings above is the key.

Newbie looking for some help with Postgres <> Django connection

[Marc Johnson]

Hi All,

I'm looking for tips/resources for a problem I'm facing with my Django app: 
https://ndcportal.herokuapp.com/ 

I'm attempting to connect my Dockerized Django app with a PostgreSQL db. 
The postgres db is already populated, and I can access the data via 
pgadmin, but I cannot figure out the appropriate settings in my 
docker-compose.yml & settings.py files to make the postgres db populate my 
django app. 

I've reviewed multiple tutorials/blog posts, including Will Vincents Docker 
& PostgreSQL tutorial 
, 
but I feel like I'm missing one or two final & crucial steps. 

When I change my DB settings for Postgres, & I bring up the app via Docker, 
I continue running into this OperationalError: 



*message:django.db.utils.OperationalError: could not connect to server: 
Connection refused Is the server running on host "db" (172.29.0.2) and 
accepting TCP/IP connections on port 5433?*

Any tips/resources/feedback would be greatly appreciated. Thanks in advance.

Best,
Marc

Re: NEWBIE

[vineet daniel]

First of all its Django and not Gjango and rather than getting mastery over
a framework in two months Id suggest that you start with python or any
programming language which has OOPs. If you are not sure what that is then
start from very basic of programming. There is no shortcut to success. Have
patience and prepare for a lot of efforts and time. Once you are
comfortable with basics of programming then bump this question again. Best
of luck.

And to give some perspective I have been working with Django @work last 10
years and I'm still far from mastering it. I'm pretty good with Django
though.

In other words it really takes a lot. Interns at work do get hang of basics
in about two months but really them to get up to speed takes somewhere
around half a year. And this is for people who do work about 8 hrs day, 5
days a week.

If you have no previous programing experience, a miracle. If you are 
already proficient with Python two months are enough to get comfortable 
with Django, but you will likely still be far from mastery.

Hi,
can you provide the folder structure of your app, and apps.py file
ensure that the name of the app is 'munichlivin_app' and name of the class 
in apps.py is 'MunichLivingConfig'

Re: Newbie question : running the makemigrations command in the terminal

[jgibson]

>From your settings file:

That makes me think that the structure of your project looks something like 
this:

\munichliving_app\manage.py
\munichliving_app\apps\MunichLivingConfig\
\munichliving_app\apps\MunichLivingConfig\models.py
\munichliving_app\apps\MunichLivingConfig\views.py
\munichliving_app\apps\MunichLivingConfig\admin.py





And `OffererProfile` is defined inside models. Is that correct?

That advice is for normal python classes. Django models have some restrictions, 
one 
being that fields are special attributes. Messing with a model's __init__() is 
not something 
you normally do as a model's class creation is highly customized.

If you're really using 2 different databases, a model's save() operation 
supports a `using` 
keyword that allows you to select the database connection[1]. Archiving becomes 
really 
easy that way.

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?

Newbie : Object copy - weird error :-)

[mickael . barbo]

Hi all :-)

I'd like to archive some data.

I did that :

class AbstractDataModel(models.Model):

xxx


class Meta:
abstract = True


def __iter__(self):

return iter([self.xxx, self.yyy, self.zzz, self.aaa,
self.qqq, self.mode_bbb])


class DataModel(AbstractDataModel):


pass


class DataModelArchive(AbstractDataModel):
# 
https://stackoverflow.com/questions/21699707/python-how-to-copy-all-attibutes-from-base-class-to-derived-one
def __init__(self, source=None):
if source is not None:
self.__dict__.update(source.__dict__)



But when I want to access data in DataModelArchive, like 
DataModelArchive.objects.all() for example,
I get 


Traceback (most recent call last):

new = cls(*values)
TypeError: __init__() takes from 1 to 2 positional arguments but 11 were

What am I doing wrong ?

The following class is kinda weird:
class DataModel(DataModel):

A class which inherits itself???

Newbie : Implementation possible ?

[mickael . barbo]

Hi community :)

I'd like to implement something like "joined image".

In Database, I'd like CoreObject to have the key of "Object1" OR "Object2" 
OR "Object3" (like foreignKey).

How can I do that ?

The context is that CoreObject is a central DataBaseFile and will receive 
information from one of ObjectX + ObjectX.pk to access ObjectX.

Thanks for your help

Micka

Re: A newbie server error occured

[Artur Gontijo]

Hi,

Did you check if you have the admin app listed in the setings.py?
INSTALLED_APPS = [
'django.contrib.admin',
'more_apps',
]

And what about your url.py? Does it have the /admin routing?
path('admin/', admin.site.urls),

So everything should work propperly, but when I open the

I have tried migrating again, I have tried using different port. The

Re: Newbie : Best data archive strategy

[Mickael Barbo]

Ok, so "audit log" is like a "snapshot". I think it's too much for what I
need.

To clarify my needs, I have a data that once "used/read", it's no more
needed.
I just want to keep it "archived", in an other place to get access to it if
I want to add some function (statistics, etc...).

So, Gerardo, it seems to be like " I want to "move" data to an archive
system (data is still relevant and useful)."

Hope this clarify my needs...

Thx Matthew and Gerardo for your help.

Re: Newbie : Best data archive strategy

[Gerardo Palazuelos Guerrero]

Hi Mickael,
When I read Archive, in my mind is a different thing, not the same as
audit. So, for one moment, think about situation/scenario you are working
on.

Archive is to manage data purge from my transactional tables; this means I
want to "delete" data (that has not more value) or I want to "move" data to
an archive system (data is still relevant and useful).

Audit is to create a perfect tracking of transitions on value overtime.
This is required due to special regulations you have.

So, it might be useful if you clarify what is the scenario you are trying
to solve.

Regards,
Gerardo.

Hi Mickael,
It saves a copy of each record every time a record is changed.  But it is saved 
in a separate table, so it doesn’t change your model’s table.

Hi,

I'd like to archive some data.

I came with this idea :


class DataModel(models.Model):
xxx

class DataModelArchive(DataModel):

The DataModelArchive database created has only "a pointer" to DataModel.

I saw a post indicating that I'll have to first create an AbstractDataModel and

Re: Newbie - Microservice in Django - Best place to start learning

[Paul Tiplady]

Assuming you're trying to build a REST API and not a HTML website, you 
should look at http://www.django-rest-framework.org/ as it provides a lot 
of djangonic convenience methods for building REST APIs with the Django ORM.

Newbie - Microservice in Django - Best place to start learning

[pratibha sharma]

Hi,

I have created 2 example websites in Django i.e. Voting and event booking 
systems. 
I want to learn to create microservice in Django. I took below example for 
it.

Service will 
1. take data from UI (it will send it in JSON format), 
2. store data in DB(MySQL)
3. Send Data to a device (in JSON format)

My mind is flooded with questions like 
how UI and service with communicate? 
how can service communicate to device? etc.

I am not sure where should I start and how to create the design for this 
work. I am new in microservice and some experience in django.

Please guide me.

Re: Newbie : Help for using RequestContext

[Andréas Kühne]

Hi Micka,

And welcome to django.

Regarding how to add things in middleware - you can add the information to
the session like this:

class SimpleBreadcrumbs(object):
def __init__(self, get_response):
self.get_response = get_response
# One-time configuration and initialization.


def __call__(self, request):
# Code to be executed for each request before
# the view (and later middleware) are called.

request.session['breadcrumbs'] = {"level0": "Adrian", "level1":
"Thomas"}

response = self.get_response(request)


# Code to be executed for each request/response after
# the view is called.

return response


Then in your templates you can do this:

{% extends 'pricing/body.html' %}

{% block content %}

{{ breadcrumbs.level0 }} / {{ breadcrumbs.level1 }}

{% endblock content %}

Regards,

Andréas

Newbie : Help for using RequestContext

[Mickael . barbo]

Hello to all Django users :-)

I'm new to Django and this is my first post.

I'd like to implement breadcrumbs on all my pages.

My strategy is to create a middleware and to use RequestContext to
add a dict to the context of each request then use the context in my html

My problem is that I don't understand how to link RequestContext to 
my request. Hereafter my code :

my_middleware.py
from django.template import RequestContext


class SimpleBreadcrumbs(object):
def __init__(self, get_response):
self.get_response = get_response
# One-time configuration and initialization.


def __call__(self, request):
# Code to be executed for each request before
# the view (and later middleware) are called.

request_context = RequestContext(request)
request_context.push({"level0": "Adrian", "level1": "Thomas"})

response = self.get_response(request)


# Code to be executed for each request/response after
# the view is called.

return response


my_template.html

{% extends 'pricing/body.html' %}

{% block content %}

{{ level0 }}

{% endblock content %}


What I'm doing wrong ?

Thx for your help

Micka

Re: Some newbie questions on CBVs and FBVs

['Simon Connah' via Django users]

 Hi,
First of all thank you very much for the reply. It was very useful. I'll 
re-read the documentation and see what I was missing out on.
The get_queryset() method was a very useful hint. That may well solve the issue 
I was having.

Hi everyone,
First of all sorry for the newbie questions it has been a long time since I 
used Django and I think I have forgotten just about everything I once knew.
I'm working on a user app for a website. I can't use the built in user model as 
I need a little more flexibility and the ability to grow in the future if 
required.
Basically I have three problems.
1) I need some views to be limited to the user who created the view.

Users do no create Views, what you are meaning is the objects "created" by the 
user (or objects attributed or associated to the user if you want to be even 
more precise)
 
 For instance I have an UpdateUser view and I only want the currently logged in 
user to be able to change their own user model data. So say I have the username 
"djangouser" and I go to UpdateView the only row in the database that I can 
change on the database server is the one with the username "djangouser". I'm 
not sure what the best way to handle this problem is?

Set the queryset attribute of the UpdateView to 
User.objects.filter(name=self.request.user) or override the get_queryset() 
method in the view:def get_queryset(self):
base_qs = super(YourUpdateView, self).get_queryset()
return 
base_qs.filter(user=self.request.user)https://stackoverflow.com/questions/8594759/django-updateview-restrict-per-user
https://docs.djangoproject.com/en/1.11/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_queryset


I could do it manually in a function based view without any problem but I find 
CBVs to be really hard to customise when you want to do something that they 
were not specifically designed to do.

Overriding the queryset is a common pattern in CBV :)
 
 At that point I just end up writing a FBV instead and doing it all myself as 
it is quicker than trying to figure out all the mixins and all the methods of 
the class.


I must be missing something simple with CBVs. Any help would be appreciated 
with this :).
 You should read the whole topic:
https://docs.djangoproject.com/en/1.11/topics/class-based-views/intro/ 
and then read the 
reference:https://docs.djangoproject.com/en/1.11/ref/class-based-views/mixins/


2) In FBVs you get passed a variable to the function with the URL conf 
variables, for instance: (path('/blah//', view, name='blah') would 
result in the FBV recieving a username parameter. Where are these variables 
stored when using a CBV?

You should read the topic :)
 

3) Is it considered bad practice to use FBVs in Django?

IMO, no :)
 
 I just find them so much easier and quicker to write. I know that CBVs result 
in less code duplication but I find I constantly need the Django docs open to 
see what each CBV supports and which methods it has available. Where as with 
FBVs I just write the code and everything works.


CBV is a pattern, if you don't embrace it, it may get in your way :)
 
Anyway, thank you for any help :).
Simon.

Of course he can. However a teacher is a huge boon, for various reasons, and if
you have a little more money than time it's really a good idea to get one.

If someone is experienced in C or Delphi, for example, their first Python code
looks like this:

for i in range(alist):

do_something(alist[i])


Unlearning the C idioms and learning the Python ones is much faster and much
easier with a teacher.

Re: Python / Django newbie looking for mentorship

[propellerhat]

If you have 20 Years of experience as a software developer you can easily 
learn python by yourself in one or two weeks. 

There is a nice tutorial on the official Python website:

> https://docs.python.org/3.6/tutorial/introduction.html

You can ask beginner questions on the Python Tutor mailing list:

> https://mail.python.org/mailman/listinfo/tutor

For learning the Django framework, I can't really comment on it, because 
I'm a newbie myself. However I'm not planning to hire anybody to each me.

Python / Django newbie looking for mentorship

[Jon Hickam]

I have 20 years experience in software but am new to OO python and django, 
 I have a project I am tackling and would be most grateful if there is 
someone I could hire to clone my repo and give me advice as I navigate my 
first project, maybe once or twice a week at the beginning?  Schedule can 
be flexible.  If you are interested send me a quick note with what your 
experience is and what sort of compensation rate you would be looking for 
and we can work out a time to chat. 
Cheers!
Jon

Re: Newbie question - data structure for game

You'll probably need jQuery. Bear in mind "size" is not absolute as it will 
depend on font family and font height.

Re: Newbie question - data structure for game

[Yaşar Arabacı]

I am also quite new to django, but I will go with something like this;

class Quote(models.Model):
quote= models.CharField(max_length=100)

class EncryptedQuote(models.Model)
quote = models.ForeignKey(Quote, on_delete=models.CASCADE)
encrypted_quote = models.CharField(max_length=100)


So, you can have multiple encryptions of any quote.

Python. I'd like to put it on a web page with Django. However, I'm not sure
of the best way to structure the data. The original quote and the encrypted
quote need to have a one-to-one relationship at the letter level. So it
could be two strings on the same row (same id)

That is the simplest, and I see no need for anything more complex.

What do you mean?

and models.py?

Re: Newbie to Novice – Using Admin DateTime Picker in your Form

[Mayank Rungta]

I am looking at making custom forms look like Django admin forms with the
widgets in place. Also, I like to do a similar thing for displaying tables.
I used a combination of plugins for sorting, filters and displaying tables
with pagination. The result was not as good. What I am hoping is to find an
easy way to reuse the features already available with django admin. But it
appears this approach is not recommended and I saw a post by a django
maintainer saying it is not likely to make this any easier in near future.
Would have been nice to have this in place, as there are a plethora of
plugins in Django & Java Script out there and sifting through them is
difficult for a newbie like me.

Looking for suitable inputs on this forum.

Thanks in advance,
mynk

Re: Newbie to Novice – Using Admin DateTime Picker in your Form

[Nate Granatir]

Just realized this thread was not necessarily about filters for the admin; 
in the case of using custom forms/views Django daterange filter may not be 
a good option.

Re: Newbie to Novice – Using Admin DateTime Picker in your Form

[Nate Granatir]

I just installed Django Daterange Filter 1.3.0 
(https://github.com/DXist/django-daterange-filter) on a Django 1.9 project. 
Took a little CSS fiddling to get it to display properly with Grappelli, 
but other than that it worked like a charm.

Re: Newbie to Novice – Using Admin DateTime Picker in your Form

[Mayank Rungta]

Most of the posts I see around this topic are dated. I was wondering if 
this works for Django 1.8 upwards. Kindly let know if anybody has 
tried/tested any of these approaches on a more recent version of Django. I 
would like to stick to this approach rather than figure a plugin/javascript 
for every widget. I already see the need for datepicker and display of 
tables, both of which are very well done in the admin interface.

sudo pip uninstall django

sudo apt-get remove django

The base install is unnecessary if Django is installed in the venv and 
it should not conflict.


It is best to avoid any base installs unless you *know* they will be 
used by all venvs






Your help is appreciated.

Newbie question regarding uninstalling Django system-wide.

I am learning how to use Django. With my first attempt I did not use a 
virtual environment instead installed Django system-wide. Now I have 
learned to utilize virtual environments. Can you help me learn how to 
uninstall the system-wide Django instance? Also, I can't recall if I used 
pip or apt-get. Or do I need to be concerned with this at all, meaning will 
the base install conflict with instances installed in the virtual 
environments?


Your help is appreciated.

Yup! Makes sense now. I hope it saves someone some trouble someday. :-)

Thanks a lot, Tim!

Re: (Newbie) Stuck with annotate() docs

[Ankush Thakur]

I'm not sure how Book.objects.first().chapters is different 
from Book.objects.first().chapters.count(), but the point is that 
"chapters" is not defined in the models at the top of that page! The 
snippet makes sense if I treat Book.chapters as another ManyToManyField 
(like authors), but it's really weird to see that error in the docs. So, 
does that mean I can report it? If yes, to who?

Re: (Newbie) Stuck with annotate() docs

Looks like a typo. Does the rest of the example make sense and work if that 
line is changed to "Book.objects.first().chapters"?

Re: Django Newbie - Tutorial Recommendations?

[Bill Freeman]

As far as learning python goes, especially if you already program in
another language, the tutorials at docs.python.org are quite good.  If you
are using python 2 instead of python 3, note the "Docs for other versions"
section in the top of the left hand column.  If you don't already program
in some other language, you might consider a book for python beginners.
