Re: Error while running '$ python manage.py collectstatic --noinput'.

[ram.mu...@gmail.com]

Hi Ihor,

Thank you for your email. We do not have any reference to heroku but 
Digital Oceanś App platform is using heroku. We resolved  the above error 
by adding this environment variable:

DISABLE_COLLECTSTATIC = 1
But we are planning to enable this once the main deployment is done.

Best Regards,
~Ram

[Ihor Dmytrenko]

Why you have heroku in your log? Remove all old dependency configs in your 
settings first and then you need specify 

```python
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static'),
]

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'

HOME_DIRECTORY_SELF_STORAGE = os.path.expanduser('~')
MEDIA_ROOT = os.path.join(HOME_DIRECTORY_SELF_STORAGE, 'public_html/')
MEDIA_URL = '/media/'
DEFAULT_FILE_STORAGE = 'django.core.files.storage.FileSystemStorage'
```

Here is the static files setting that we have in our settings.py file:


*STATIC_URL = '/static/'STATIC_ROOT = os.path.join(BASE_DIR, 'static')*

How can I use for dental clinic, For example, do I need to include 32 
fields from the model to specify 32 teeth, or is there a way to do it in 
one?

 Hello,

 I'm brand new to Django taking an online course in Python.
 I created a project named 'django_test' and I'm in the process of 
 creating a very simple app named 'Hello_World'.

 I'm trying to modify the urls.py file in my 'django_test' project for 
 the app 'hello_world'.
 My code in urls.py follows:
 from django.contrib import admin
 from django.urls import path
 urlpatterns = [
 path('admin/', admin.site.urls),
 path('hello_world/', include('hello_world.urls'))
 ]

 The return error is name 'include' is not defined

 I tried to import include with the statement from django.conf.urls 
 import include
 which also failed.

 Thank you for reading my post.

Re: Error loading static file from a NAS (CIFS mounted) Not 404...

Okay I think I know the problem.

Apache2 has a bug with CIFS, set EnableMMAP Off in config will solve this.

You appear to half only half asked your question and have provided no
context.

Do you have a route named 'register'?  [ URL(, name="register") ] (I am
guessing no, else this specific error would not occur)

Guessing what you forgot to mention, check out some of the great tutorials
available via a google search on account registration and signup with
Django.

That you made a typo in your settings.

Using an editor that can highlight such mistakes can be quite 
convenient. Not only would it have saved you from having to post a 
question here, you wouldn't even have to (re)start your Django 
development server.

Re: Error: pg_config executable not found. (psycopg2 for postgres in docker not successfully installed)

[Adeyemi Deji]

Hi,

I believe the the binary package is suitable for development and I plan
integrating docker in my company's upcoming project, so I needed a package
best for production.

Thanks kasper

Great to hear you figured it out and thanks for sharing. Out of 
curiosity, any reason why you chose to build the psycopg2 package from

I would assume using the prebuilt binary would have been simpler and of 
course make it much faster to build your container than building your 
own package from source.

Seems like you need the postgresql development package or similar to 
build psycopg2 from source. Try using the binary package 
(psycopg2-binary) instead as suggested here:


#0 26.78       If you prefer to avoid building psycopg2 from source, 
please install the PyPI

#0 26.78       'psycopg2-binary' package instead.


Alternatively, ensure the postgresql development package is installed in 
your Docker container.

Make sure the template directory is located in the app directory or if it
is in a different directory, ensure the location is specified at the
template section  in the settings.py file

You should run `python manage.py makemigrations` and then `python manage.py
migrate`

Re: Error during template rendering

[Antonis Christofides]

Hi!

The error message 'relation "curriculum_standard" does not exist' has been 
produced by PostgreSQL, and Django merely repeats it. In other words, Django is 
telling you that while it was doing what it was doing, an error occurred in the 
RDBMS, and it is showing you the error message that the RDBMS returned.


People who, unlike me, have studied relational calculus often use the word 
"relation" for what I call a "table". I don't know why. I once picked up a 
relational calculus book to take a look, but it was too heavy for my taste :-) 
(If someone can explain in simple terms I'm eager to read.) So the system is 
telling you that table "curriculum_standard" does not exist.


This probably means that you need to run "python manage.py migrate".

Regards,

Antonis

I think you're a bit confused. I answered the original question with the

Not sure if GMail doesn't support threads or what else might be the

Simple.
A circular import happens when you have fileA that has something say a
class A, then another file B with also a class B
Then class A imports class B from file B which is also importing class A
from B.
So the program keeps importing and never completes the cycle.

Solution,
If you have to use the two like that, then put them in the same file. It is
always my shortcut.

Remember that Django is a Python framework, so circular imports are 
mostly a Python thing not specific to Django:

You need to replace "\path\to\your\local\clone\django\" with the actual 
path to your clone of Django.


I guess whoever wrote whatever documentation you are following assumed 
that would be obvious.


One might wonder why you are trying to install Django this way?

 Hi All,

 I have a customized/override "*changelist_view.html*" to display
 hierarchical data in Django admin panel.

 The problem is that the default form to add the Model data throws below
 error when clicked the button "add category". Please refer to the attached
 screenshot.

 [image: dj_1.jpg]

 *NoReverseMatch at /admin/category/category/add/*

 *Reverse for 'app_list' with keyword arguments '{'app_label': ''}' not
 found. 1 pattern(s) tried: ['admin/(?Pcategory|auth)/$']*

 [image: dj_2.jpg]

 If I remove the function
 "def changelist_view(self, request, extra_context={}):", the model starts
 appearing fine. Please refer to the screenshot below. But then I loose the
 functionality to display custom hierarchical data.

 [image: dj_3.jpg]

 How can I still show the default form to add data to the model and
 override the  *changelist_view.html*" .

 Appreciate any help in advance.

 Thanks
 Rahul

Re: Error - module 'django.db.models' has no attribute 'FieldDoesNotExist' when adding FK relationship object

[Lloyd Dube]

Addendum: the Release model is declared as follows:

from django.db import models
from tinymce import models as tinymce_models

from artists.models import Artist
from bands.models import Band
from labels.models import Label


class Release(models.Model):
artist = models.ForeignKey(Artist, on_delete=models.CASCADE)
band = models.ForeignKey(
Band,
on_delete=models.CASCADE,
blank=True, null=True
)
title = models.CharField(max_length=200)
label = models.ForeignKey(Label, on_delete=models.CASCADE)
cat_no = models.CharField(
max_length=200,
blank=True,
null=True,
default='UNKNOWN'
)
country = models.CharField(
max_length=200,
blank=True,
null=True,
default=None
)
RELEASE_FORMAT_CHOICES = [
('LP', 'LP'),
('10INCHALBUM', '10" ALBUM'),
('7INCHEP', '7" EP'),
('12INCHEP', '12" EP'),
('12INCHSINGLE', '12" SINGLE'),
('10INCHSINGLE', '10" SINGLE'),
('7INCHSINGLE', '7" SINGLE'),
]
release_format = models.CharField(
max_length=200,
choices=RELEASE_FORMAT_CHOICES,
blank=True,
null=True,
default=None
)
year = models.PositiveSmallIntegerField()
genre = models.CharField(
max_length=200,
blank=True,
null=True,
default=None
)
bio = tinymce_models.HTMLField(blank=True, null=True)
date_created = models.DateTimeField(auto_now_add=True)
date_modified = models.DateTimeField(auto_now=True)

class Meta:
verbose_name = "release"
verbose_name_plural = "releases"

def __str__(self):
return self.title




I suspect that something is going on with migrations. All migrations have
been run and a user is already capturing data on a staging server, so I do
not want to recreate the database.

~ Lloyd

Re: error save to model on a onto many relationship

[Abdul Qoyyuum]

What happens if you try and save choice#3 in question 1 only? Can you try 
in the Python shell?

Re: Error finding Upload-Folder. Maybe it does not exist?

[Mic]

I tried to create the missing `blast/db` folder in the following way but it 
still does not work:

```
*$ docker-compose exec web /bin/bash*
*# pwd*
*/code*
*# mkdir -p blast/db*
*# mkdir -p i5k/blast/db *
```
Where do I have to create *blast/db* folder?

Thank you in advance,

Michal

Re: error

[RANGA BHARATH JINKA]

Hi,
I think you have to generate an app password from Gmail and use it instead
of your password.
Refer to this link. https://support.google.com/mail/answer/185833?hl=en

Re: Error at the return of an AJAX POST in DJANGO

[Malcolm MacKinnon]

In your success function, you are assigning the variable e = 'OK', so in
your if statement, it appears to throw an error. If you change it to
if(e=="OK"), does it work? Note the two equal signs, == .

RE: Error at the return of an AJAX POST in DJANGO

['Trevor Woolley' via Django users]

Walter,

If your copy and paste is accurate you have too many closing brackets in the 
ajax section.

Try removing one of these from the end of the ajax section:
});

Re: Error at the return of an AJAX POST in DJANGO

[Malcolm MacKinnon]

I'm not a JS expert, but is your success function defined properly?
if(e="OK") vs. if(e=="OK")

Not sure, but looks like an extra closing bracket in line 9 of the ajax code

Re: Error configuring URLs for a beginner

[Arpana Mehta]

Do you have a *urls.py* in your 'app' folder? (And app is a reserved
keyword, it would be better if you use some other name to avoid confusion
even later )

Re: error at deployment

[Kasper Laudrup]

Hi Sayur,

On 22/08/2020 22.53, Sayur Patel wrote:

hello i am beginner and this is my first project.



Welcome to developing websites using Django. Hope you'll enjoy it.



anything am i missing?



You should probably let us know a bit about what Phusion Passenger is 
and how you have deployed it there. I have no experience with that, but 
someone else might and there's a greater chance they could help if you 
tell us how you have deployed it.


Do you get an error if you use the Django builtin development server?

Also, as someone else have already mentioned, you should check the logs. 
There's probably some way to do that with Phusion Passenger, if you 
don't know how, try to figure that out. You'll need that sooner or later 
anyway.


Finally, what happens when you click the "Technical information for 
administrator of this website" link? Remember, you're the administrator 
of this website ;-)


Good luck and kind regards,

Kasper Laudrup

Also that error comes about if you didn't  create well the python
application like maybe you missed the application root, or you didn't
replace the code in  your wsgi.py with this line. from myproject import
application

You are missing python manage.py collectstatic, this is used to copy your

Re: ERROR

[Kovy Jacob]

Are you switching into your projects directory and then using 'python
manage.py runserver' from command prompt/terminal to run your website?

Re: Error in sending mail

[MUGOYA DIHFAHSIH]

i think it is repeating it cos the email you put in the settings.py is the
same email you used for clients to send to contact you through.
What i mean is a person contacting you sends the email to
rubymoti...@gmail.com and it is the same email you used i the settings.py
to permit django app send email.
