Noob question: Is the User model compatible with subscription-style website?

[Tom Tanner]

I'm working on a Django-powered subscription website with a Django-powered 
CMS backend. Can the User model, or a derived class, be made to be 
compatible with this idea? In my case, I want to store a user's username, 
password, and subscription ID.

Re: Syntax Error when trying to migrate to Postgresql

The problem was with the quotes being weird format, had to copy and paste 
the correct quotes in for it.  Thanks for the help!!

Re: AttributeError: 'module' object has no attribute 'lru_cache' with python 3.6.4 and Django 2.0.2

[PASCUAL Eric]

Maybe it works like this in Windows (I don't know since having left this world 
since long now), but Greng mentioned a Debian environment inside his Docker 
container. Hence my remark.


By the way you mentioned "DLLs". Geng's trouble seems to be related to Python 
packages finding, not binary libs. In Linux, they are governed by different 
search paths.

Hi,



Normally you shouldn't have to add site-packages in the PYTHONPATH since it is 
supposed to be already. If not, packages installed via "sudo pip install" would 
not be found.



I've packaged a lot of applications in Docker containers, and never had to 
modify PYTHONPATH.



Your problem is maybe be lurking elsewhere than PYTHONPATH, and this change has 
just created a new one which is hiding the original one, but not solving it at 
all.



Best

Hi,



I'm trying to set up the following configuration in Docker

python: 3.6.4

Django: 2.0.2

Apache/2.4.10 (Debian)



First, I was getting the error



ImportError: No module named django.core.wsgi



Then I added Django to PYTHONPATH



export PYTHONPATH="/usr/local/lib/python3.6/site-packages"



the previous problem has gone away but now there is another one



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

Apache configs contains the following line



WSGIScriptAlias / /www/settings/wsgi.py

where /www/settings/wsgi.py is  actual path to wsgi.py file.



What could be wrong?



Thanks,

Re: Basic note/trello app - how to link model object IDs

[Lylio]

Thanks for the reply Melvyn - I'm slowly getting there!

So, I now understand how to insert the unique object reference. After 
creating card.html, and defining card in views, my list element URL is:

{% for card in cards.all %}
{{ card.title 
}} 
{% endfor %}

And if I click on the second card object in the list, it opens 
up http://127.0.0.1:8000/scrumbuddy/card/2 - hooray, progress!

Ok, so now I understand what *card.id* is and I use this to references the 
model object instances. So, I presume I need to use that ID to render the 
details of each card into the body block of card.html.

Would that require editing the card view? All I have at the moment is:

def card(request):
return render(request, 'scrumbuddy/card.html')


So somewhere in here I'd create a reference to *card.id, *and perhaps pass 
the id within a context variable?

Thanks again guys, it feels good to be making some progress! Really 
appreciate your help.

Your reasoning is flawed. The model that is inlined never has a foreign key to 
the model that it is inlined with. It is the reverse of the foreign key. 
Foreign keys are not inlined, they are rendered via select widgets.

Something else is preventing this from working and without code and 
corresponding backtrace we cannot diagnose what.

You did not follow this advice, or you would already know how to tie the url

RE: Basic note/trello app - how to link model object IDs

[Matthew Pava]

You’ll want to use card.get_absolute_url.
See https://docs.djangoproject.com/en/2.0/ref/models/instances/#get-absolute-url
In your get_absolute_url, you should probably use the reverse method to use the 
name of a URL rather than hard-coding it in the method.  That’s the second 
example in that section.

Thanks for the reply Gonzalo, I really appreciate the feedback.

So, conceptually I understand how the remaining pieces of this app fit together 
- but could I ask for just a little more of your help as I'm struggling with 
coding the details of what's needed.

Let's start basic - I've got some 'cards' in my database and on one of the web 
pages the title of the card is presented in a list (with some CSS styling to 
present the list item as a rectangle):


   {% for card in cards.all %}
   {{ card.title }}  
   {% endfor %}


I'd like to click on one of the items in the list and open up a new page 
showing all the database details for that particular list item (title, 
description, time of creation, etc). Roughly, would I change the list items 
into links:


   {% for card in cards.all %}

It isn't necessary, but it is a good idea
What you need is to create a view that renders such template.
I suggest you write your own view function that does that, but what
you'd usually do is just use a generic view and either pass it the
template you want to use, or name the template in a way the generic view
will find it on its own.
See:
https://docs.djangoproject.com/en/2.0/topics/class-based-views/generic-display/

Yes, in general, every Django model instance has an id (unless you
specifically tell it not to), and you can use it to create urls for the
detail view I mentioned earlier. This is a good start, but you'll later
want to add a SlugField to your Card model, and use that instead of the
id so urls look nicer.

I can assure you using Django for a project like yours is *very*
straightforward.
When in doubt, revisit the Django tutorial. This part is a good one for
where you're at: https://docs.djangoproject.com/en/2.0/intro/tutorial03/

RE: AttributeError: 'module' object has no attribute 'lru_cache' with python 3.6.4 and Django 2.0.2

[Matthew Pava]

I’m not familiar with Docker, but I did have to add the path to Python 3.6 DLLs 
in my WSGI configuration in my Apache configuration file.
WSGIPythonPath ${project_path};${virtualenv};C:/Python36/DLLs;

Hi,



Normally you shouldn't have to add site-packages in the PYTHONPATH since it is 
supposed to be already. If not, packages installed via "sudo pip install" would 
not be found.



I've packaged a lot of applications in Docker containers, and never had to 
modify PYTHONPATH.



Your problem is maybe be lurking elsewhere than PYTHONPATH, and this change has 
just created a new one which is hiding the original one, but not solving it at

Hi,

python: 3.6.4
Django: 2.0.2

First, I was getting the error

Well, i know this and the related entry is accessible even without 
explicitly defining the related_name. You can change defaults defining the 
related_name, tho. 
But still trying to add a UserInline to the ProfileAdmin wont work due to 
the missing FK on the user model.

Just for clarification, i dont do any mysterious magic: the property works 
like this:

@property
def username(self):
return self.user.username
username.fget.short_description = "Username"

@username.setter
def username(self, username):
self.user.username = username
self.user.save()


So with everything else failing .. although i only want to be able to edit 
this one field of the actual user, it looks like i have to show a useradmin 
with a profile inline admin?
AFAIK this can only be done with a separate admin site, because there can 
only be one Admin for any model thats why i wanted to have some other 
solution. 

Maybe someone knows a better solution?

Re: edit model properties in the admin

[Adler Neves]

You can have an OneToOneField in the profile referencing Django's User model 
with `related_name='profile'`, so you can access information from there as 
`user.profile.birthday`. An useful link: 
https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

About the admin interface changing the model, I guess you're somehow editing 
`models.py` files. Are you making the migrations, applying them to the database 
and reloading the server? If you're not persisting changes that way, how do you 
patch models in memory every startup and ensure database schema is compatible 
with your models?

Re: edit model properties in the admin

[Andy]

As an example i wanted to have the username editable inside the profile. 
Since the Django default user doesnt have a foreign key to profile i cant 
just use an inline admin for the user model, so my next idea was to solve 
it with properties just getting from and saving to the related user model.

What would mean to edit a property (assuming this means an attribute
that isn't a model field) in your app? Where would the data go?

The Django admin will look only for Django fields in the edit forms,
that's why you're getting the errors.
Since list_display is only for showing data, it will display any
attribute in your model.

> Can i actually do this? So far i didnt find any hint on editing properties 
> with the admin.

What you can do is use a custom model form and add fields to it for the
attributes you want to be able to "edit", but you'll also need to define
what happens with the data either in the custom form class itself, or in
the ModelAdmin class by extending the change_view method.

See the documentation for details:
https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.form

If you haven't already done this, try to restart from a fresh new virtualenv 
inside which you'll install Django and the additional packages you've added (if 
any). Then restore a copy of your project in this context (if by chance you 
work with git, a simple git clone will do the trick) and test your app again.


Hoping you haven't already messed your system Python by installing stuff in 
sudo mode. The situation could be a little more complicated then.

I want to seek some advice about the error. All of my pet projects in my

confirm that when I started playing around with the projects, I have installed 
Django inside virtualenv without using "sudo". Now, I can't run python

freeze are different from before which doesn't include Django in the list.


Any advice pls?

Hi,


The copy/paste of the project tree will work of course. Chances are that 
unwanted files can be brought too, but this should not be a problem in a first 
stage.


I have used rsync or tar archives to deploy Django projects in some cases, and 
it worked fine.

that's odd. Whenever I test a pacakge, it's always installed first in

not yet in github, can I just copy and paste them in a new folder with new 
virtualenv?

Can you provide the error messages trace ? It can greatly help understanding

If you haven't already done this, try to restart from a fresh new virtualenv 
inside which you'll install Django and the additional packages you've added (if 
any). Then restore a copy of your project in this context (if by chance you 
work with git, a simple git clone will do the trick) and test your app again.


Hoping you haven't already messed your system Python by installing stuff in

Subject: importError: Count Not import Django inside Virtualenv

Hi,

I want to seek some advice about the error. All of my pet projects in my 
desktop are getting the same error even though virtualenv is activated. I can 
confirm that when I started playing around with the projects, I have installed 
Django inside virtualenv without using "sudo". Now, I can't run python 
manage.py runserver and the packages that I am getting whenever I run pip 
freeze are different from before which doesn't include Django in the list.


Any advice pls?


Thanks,
Jarvis

[Andy]

Im trying to have a custom admin that is also able to edit some model 
properties, but putting those properties into my fieldsets its complaining

Unknown field(s) (foo, bar) specified for Profile. Check 
fields/fieldsets/exclude attributes of class ProfileAdmin.

The properties work in list_display, but im missing something for the edit page.
Can i actually do this? So far i didnt find any hint on editing properties with 
the admin.

I prefer messing with standard distutils/setuptools commands to avoid

@Jason,

It's weird because couple of days, I can still run these pet
projects without any error. If I go to venv folder
virtual/lib/python3.6/site-packages, I can see django there. It
seems that even though virtualenv is activated, the packages I
installed inside it are not recognized by the system.

Re: importError: Count Not import Django inside Virtualenv

[tango ward]

that's odd. Whenever I test a pacakge, it's always installed first in
virtualenv. Maybe when I updated my system? Btw, I have some projects which
are not yet in github, can I just copy and paste them in a new folder with
new virtualenv?

Re: Syntax Error when trying to migrate to Postgresql

[Andy]

Could you post a few more lines of this settings.py? Preferably the whole 
DATABASES definition.

Just in case there actually is a weird invisible character try retyping 
'postgresql', but more likely it looks as if you are using wrong quotation 
marks other than ' or ". I dont even have on my keyboard whats in your 
error message.

Hi,


Hard to say without knowing the exact context, but my gut feeling is that 
you've modified a system wide library at a moment (maybe inadvertently).


My own experience is that it's easy to mess with Python libraries when

Even if far less harmful, then --user option is to avoid for projects related 
libs, for the same reasons.
