2020-07-30 Thread Mira

Hi All,

I am using Python 3.6 and My Application was working fine with Django 2.2
but now i am getting below error.

Any help related with this topic would be greatly appreciated.

$>python3 manage.py runserver

Watching for file changes with StatReloader

Performing system checks...

Attribute 'field_classes' is ignored when using with Admin GenericInlineForms

2020-07-30 Thread Yuriy Tupychak

When I'm trying to change image field class withfield_classesand use it 
in GenericTabularInline- nothing happens and Django's default 
ImageFieldis used.


/admin.py/

classImageAttachmentForm(ModelForm):
classMeta:
model = ImageAttachment
fields = ['image']
*field_classes *= {
'image': *CustomImageFormField*,
}
classImageAttachmentInline(GenericTabularInline):
form = ImageAttachmentForm
model = ImageAttachment
@admin.register(Pet)
classPetAdmin(ModelAdmin):
inlines = [ImageAttachmentInline]


I've submitted a *probable fix* here: 
https://github.com/Tuoris/django/commit/b7151a0860363487d120e168866c9b95e715b526


Thanks, tuoris

IntegrityError: null value in column "user_id" violates not-null constraint

2020-07-30 Thread Dinolin yp job

I'm trying to save image in postgres database. I have upload model which 
has a foreign key reference to the extended custom user model. But it shows 
the following error


uploads/model.py
from django.db import models
from django.contrib.auth import get_user_model

User = get_user_model()

class Upload(models.Model):
upload_file = models.ImageField(upload_to='uploads/')
upload_date = models.DateTimeField(auto_now_add =True)
user = models.ForeignKey(User, on_delete=models.CASCADE)


What am I missing? Thanks in advance

Re: IntegrityError: null value in column "user_id" violates not-null constraint

2020-07-30 Thread oba stephen

>From the error, it states that you are trying to add an upload object to
the database without a user. And from your model.py, the User foreign key
does not have a null=True, and blank=True. So you can't save a null value
for that user field.

Re: Django3 runserver error

2020-07-30 Thread 'Amitesh Sahay' via Django users

It seems to me as if there is a mismatch of some in-built functionality. Can't 
say for exact though. Did you follow the migration rules from one version to 
another ?

Re: Django modelformset is_valid method retrieves entire model from database

2020-07-30 Thread Shaheed Haque

If you use the "empty_form
"
functionality, you may also wish to check that. In my case, I had added
queryset filtering for the normal form case, but recently noticed to my
horror that constructing the empty_form caused my filtering to be skipped.
The effect was similar to yours, returning every possible object for each
field in the form not only hammering the database, but the browser/renderer
too.

I *think* that if I had been able to use limit_choices_to

then the (undocumented?) get_limit_choices_to functionality on form fields
might have solved both problem cases. However, that was not an option for
me.

Re: IntegrityError: null value in column "user_id" violates not-null constraint

2020-07-30 Thread oba stephen

You can create an upload form with an Image field, then when saving the for
set the User field to request.user.

Do you have an UploadForm already in your forms.py? if yes, show me with
the view that handles.

Need Urgent Solution File explorer in django web app

2020-07-30 Thread Vishnu Bhandari

Need to create a functionality(Preferred lang- python with Django) in web
application to access file system of any server(that might be any of this-
AWS, GCP, Azure)
Keypoints:-
- Whenever user logged in, there will be multiple group of servers shown on
UI section
- In group of server, there will be multiple servers(can be linux, windows,
fidora, etc.)
- when user clicks on any of the server(No need to put username, password
of that server as it will be handled in backend),all the componants of
server will be fetched
- one of them is File System(Button click)
- On the click of File System Button(In backend, it should execute the
commands on the server and returns the result), it will browse the
directory structure, sub-directories, files present on that particular
server depending upon the permissions given to user
- User should able to perform the file transfer(from remote server to local
server and vice-versa), delete the directory/sub-directory/files, open the
file, edit, and save it again.
- All these operations need to perform in web application, just like any
SFTP Clients e.g., sFTP Client, FileZilla,  User should have the file
explorer on UI(not desktop file explorer, totally on webapplication)


- We have tried to achieve this using network library PARAMIKO which can be
used to run the custom commands on any remote server.
- In this we accessed the directories, sub-directories, files present on
remote server
- But for building directory structure with filesystem functionality as
described above could not find

Re: IntegrityError: null value in column "user_id" violates not-null constraint

2020-07-30 Thread oba stephen

first in your UploadSerializer fields use fields = "__all__"

Then you can use this in your views:

*def post(self, **request, format=None**):*
*upload_file = request.data.get("upload_file"**)*
*upload_date = **request.data.get("upload_date"**)*






*user = request.userdata = {'upload_file': upload_file,
'upload_date': upload_date, 'user': user}serializer =
VoteSerializer(data=data)if serializer.is_valid():
serializer.save()return Response(serializer.data,
status=status.HTTP_201_CREATED)return Response(serializer.errors,
status=status.HTTP_400_BAD_REQUEST)*


This should do it for you.

 From the error, it states that you are trying to add an upload object
 to the database without a user. And from your model.py, the User foreign
 key does not have a null=True, and blank=True. So you can't save a null
 value for that user field.

 From the error, it states that you are trying to add an upload object
 to the database without a user. And from your model.py, the User foreign
 key does not have a null=True, and blank=True. So you can't save a null
 value for that user field.

Re: Can't get rid of "CSRF verification failed. Request aborted.: when submit form with nothing selected

2020-07-30 Thread Isha Thakur

Hi,

I think, it can help you.


You should never compare the complete HTML content. Just check the 
functionalities. In case you need disabling the csrf at any cost, following 
logic should help I guess.

In your views.py file, add the following package

from django.views.decorators.csrf import csrf_exempt

Then just before the function definintion, in which you are performing your 
checks, add this snippet:

@csrf_exempt

This will disable the default verification of csrf. Even if your incoming 
request has a hidden csrf token, your server function will completely ignore 
it. This should do the trick of disabling the csrf.

By default, Django checks for the CSRF token in all POST requests. Remember to 
include the csrf_token tag in all forms that are submitted via POST.

Please place csrf_token in  tag. You have placed it outside of form tag.

Django Mod WSGI Key missing in header

2020-07-30 Thread deepak gupta

Hi All,

We are trying to send the Client_id, Session_id key from other system to
our Django Application. But the same is not received in header.
Is there anyway Django can allow the keys with _.
We are using Apache web server & Mod wsgi.

Regards,
Deepak Gupta

Re: Admin list sorting problem

2020-07-30 Thread Derek

I've had to do something similar to handle species.

I'd suggest breaking "pure" database design and creating a new field - say, 
"sort_name".  This is created "on save" (obviously you can run a script to 
quickly generate this field's values for all existing records).  You don't 
show "sort_name" on the admin interface; what you then do is create a new 
attribute on the chemical model - call it "_name"; this displays the actual 
chemical name, but the sort is set to your new field.  Something like:

def _name(self):
return '%s' % self.name
_name.admin_order_field = 'display_name'

In the Admin, only show "_name" and not "sort_name" or "name".

Apologies for lack of proof reading; the example code should be:


def _name(self):
return '%s' % self.name
_name.admin_order_field = 'sort_name'

 Do you have an UploadForm already in your forms.py? if yes, show me
 with the view that handles.
