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:
Internal Server Error: /en/admin/cms/page/copy-plugins/

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?

I've investigated, it's because of the intermediate delete confirmation dialog. When invoking the "delete selected items" action it sends the request with all the entries in correct format (YYYY-MM-DD...), but then after confirmation dialog I see this in the delete_selected_confirmation.html:
<input type="hidden" name="{{ action_checkbox_name }}" value="{{ obj.pk|unlocalize }}">
After this timestamp is being sent in the format I see on page (June 12, ...) and the code hiccups.
It will require someone from django developers to understand how to fix it best, I'm afraid.
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'

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
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",
}
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.
