Problem Description:
The DRF UniqueTogetherValidator is displaying some odd behaviour.
For example:
models.py
class MyModel1(models.Model):
field1 = models.IntegerField()
field2 = models.ForeignKey('MyModel2', on_delete...)
class MyModel2(models.Model):
field3 = models.IntegerField()
serializer.py
from rest_framework.validators import UniqueTogetherValidator
class MyModel1Seriealizer(serializers.ModelSerializer):
class Meta:
model = MyModel1
validators = [
UniqueTogetherValidator(
queryset=MyModel1.objects.all(),
fields=('field1', 'field2_id')
)
]
When the condition is violated by field1 only, it reports back a good 400 response with a message in non_field_errors, but when the violated field is field2 (or its _id), the server gives back a response code 500 (meaning Django caught it at the database/ORM level).
The actual use-case is here on my GitHub.

if field2_id is foreign key, you don't need to put field like that.
just put field2
from rest_framework.validators import UniqueTogetherValidator
class MyModel1Seriealizer(serializers.ModelSerializer):
class Meta:
model = MyModel1
validators = [
UniqueTogetherValidator(
queryset=MyModel1.objects.all(),
fields=('field1', 'field2')
)
]
and you can try post json data like this:
{
"field2": 1,
"field1": "test",
}

I am new to Django. I think it's really easy one for Django expert, so I wish I could get help from you.
I have two tables in SQLite DB-namely Process and ScrapedData. While migrating models I have had several error so I just created these two tables manually by Navicat.
Following shows models.
class Process(models.Model):
PLATFORM=(
('Instagram','Instagram'),
('Facebook','Facebook'),
('LinkedIn','LinkedIn'),
('TikTok','TikTok'),
('Youtube','Youtube'),
('Twitter','Twitter')
)
hashtag=models.CharField(max_length=300)
platform=models.CharField(choices=PLATFORM,max_length=9)
date=models.DateField(auto_now_add=True)
class ScrapedData(models.Model):
homepage=models.CharField(max_length=500)
email=models.CharField(max_length=100)
process_id=models.ForeignKey(
Process,
on_delete=models.CASCADE,
verbose_name="the related Process")
Then I tried to insert data into these two tables then I got following error.

After I execute app I got a row newly inserted in Process but ScrapedData always shows me empty rows..
This is process table
This is ScrapedData table
What I want is 1 process row with several ScrapedData rows with one to many relationships.
I have no column named process_id_id in ScrapedData table but log always say this error.
Please help me. Thanks in advance.

group = Groups.create(name="test")
User_group.create(uesr_id=user,group_id=group)
I created a user table and a group table through peewee, and then there is a many-to-many association table user_group, I created a user test and a group test through the function create_user. I want to add a field to the user_group table. I followed the official website method. Why would I get an error?

I suspect that there is any problem with my mysql, so I execute the insert command under the command line. But found that it can be inserted successfully
Can you give me some help, thanks in advance
You have a typo:
User_group.create(uesr_id=user,group_id=group)
It should be:
User_group.create(user_id=user, group_id=group)
It's also not comme-il-faut to add the "_id" suffix to your foreign-key fields. Better to:
class User_group(BaseModel):
# Peewee will use "user_id" and "group_id" for the column by default
user = ForeignKeyField(Users,backref='user_groups')
group = ForeignKeyField(Groups,backref='user_groups')
I am trying to filter my product list with price less than filter but getting error. I guess the error is I am unable to pass parameters correctly.
any help would be appreciated.
if you require anymore details, please ask.
Note: it does not works even if I pass the query on filter body static.
thanks in advance.
my method:
def getfilter(request, format=None):
kwargs = {
'{0}__{1}'.format('price', 'lt'): Decimal('1000.00'),
# '{0}__{1}'.format('name', 'endswith'): 'Z'
}
products = Product.objects.all().filter(**kwargs)
serializer = ProductSerializer1(products, many=True)

It seems like the conversion from Decimal to string failed:
'{0}__{1}'.format('price', 'lt'): Decimal('1000.00'),
and corresponding SQL:
< %(0)s
I guess one of this possible troubles:
your model field price type is incorrect for this conversion
your decimal value have two zero numbers after decimal point - try to
remove the last one
Have a csv file with data. do parse that.
file_reader = csv.reader(f, delimiter=';')
for row in file_reader:
data = UserDataCsv()
data.user = files.user
data.file_hash = request.FILES['file']
data.file = UserFiles.objects.get(id=file_id)
print(row[0])
data.material = row[0]
But when i try add new row got error.

How i can fix that?
I'm using Django-CMS and I created some custom plugins that I use in several pages but in one of the pages I can't publish nor I can't copy plugins that are nested and gives me the same error in both situations:

I've checked in my database and in the cms_cmsplugintable exists a column named position but there's no entry with position null. Do you have any idea what's going on?
