Pycairo error while deploying django app on AWS
My app is deployed on AWS ElasticBeanStalk was working fine up until one hour ago and now it is giving 502 Bad gateway error.

Elasticsearch refuses connection to python Django
I have a Django project with a model: class ParentFoodDirectory(TimeStampedModel): uuid = models.UUIDField(default=uuid.uuid4, editable=False) name = models.CharField(max_length=1000, null=False, blank=False) active = models.BooleanField(null=False, blank=False, default=True) p_id = models.IntegerField(null=False, blank=False) class Meta: verbose_name_plural = "Parent Food Items" def __str__(self): return self.name This model has more than 10 million objects. The searching on this gets really slow that's why I decided to use elastic search. I set up Elasticsearch on a different instance and used ngnix on the machine. Now the elastic search was available through the ext IP. Then in order to map this mode on elastic search I made a dcouments.py file: from django_elasticsearch_dsl import Document, fields from django_elasticsearch_dsl.registries import registry from .models import ParentFoodDirectory @registry.register_document class ParentFoodDirectoryDocument(Document): name = fields.TextField() active = fields.BooleanField() p_id = fields.IntegerField() class Index: name = 'parentfooddirectory' class Django: model = ParentFoodDirectory I mentioned the host in my settings: ELASTICSEARCH_HOST = 'http://35.141.96.246/' ELASTICSEARCH_DSL = { 'default': { 'hosts': '35.141.96.246', }, } But while rebuilding index, I get the following error: elasticsearch.exceptions.ConnectionError: ConnectionError(<urllib3.connection.HTTPConnection object at 0x7f49febf8d90>: Failed to establish a new connection: [Errno 111] Connection refused) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x7f49febf8d90>: Failed to establish a new connection: [Errno 111] Connection refused) Any clue on what might … -

Sendgrid smtp cannot verify sender identity
I have a Django application that uses sendgrid’s smtp relay for sending emails. However I am receiving a 550 error. I authenticated my domain in sendgrid and I added a send user with the “from” email no-reply@mydomain.com. This email however doesn’t actually exist, is this the cause of my error? If so wouldn’t this mean I have to setup an email server to use no-reply@mydomain.com, and isn’t the whole point of sendgrid to not have to create a email server? This is a point of confusion for me because I thought sendgrid authenticates your domain to act as a email server for it I Set the following env variables: EMAIL_HOST=smtp.sendgrid.net EMAIL_PORT=587 EMAIL_USE_TLS=True EMAIL_HOST_USER=“apikey”EMAIL_HOST_PASSWORD=SG.********* DEFAULT_FROM_EMAIL=no- reply@mydomain.com My error log is: “smtplib.SMTPDataError: (550, b'The from address does not match a verified Sender Identity. Mail cannot be sent until this error is resolved. Visit https://sendgrid.com/docs/for-developers/sending- email/sender-identity/ to see the Sender Identity requirements')” -
class Meta Django
Good evening, In fact I would have liked to have explanations in relation to the Meta class. In my case, if I don't code it, it doesn't change anything. I imagine it's because in the settings I filled in the user model used for the project. But beyond filling in the class linked to the form, I have trouble understanding the fields attribute. Because I can interchange, remove items from the list, it doesn't change anything. Thanks in advance class UserPasswordChangeForm(PasswordChangeForm): old_password = forms.CharField(widget=forms.PasswordInput) new_password1 = forms.CharField(widget=forms.PasswordInput) new_password2 = forms.CharField(widget=forms.PasswordInput) class Meta: model = Shopper fields = ["old_password", "new_password", "new_password2"] Apart from the model, what is the class meta for? -
django serializer dictfield vs jsonfield
I have a column custom_property of type jsonb in postgres. I need to validate a payload for this column. payload: { "description": "test description3", "custom_property": { "access": "Yes" } } I have a serializer: class MySerializer(serializers.Serializer): description = serializers.CharField(required=False, max_length=500) custom_property = serializers.DictField(required=False) Should I use DictField or JSONField for this column? It seems that in both case, it needs to be formatted to json string first with json.dumps(). -
How to get the access_token in Django-all auth with GitHub social account?
I am working on a project and successfully set up the django-allauth using GitHub social account in an app named 'auth'. Now, I need profile details and access to a particular repository of authenticated users in another app, and for that, I need an access token but I am facing errors with that. How to do it?

Running django web app over a web path in a sandbox
At the place where I work we have the option to deploy applications through a sandbox. With that a problem arises and that is that for each application running we have a web path, for example: domain.com/path/of/app_django/. With that base path I can access the main view of my application (0.0.0.0:8080/ >> domain.com/path/of/app_django/) however when trying to access other views django uses the main domain, for example domain.com/my_url instead of being domain.com/path/of/app_django/my_url.

How to read byte strings generated by marshall on the jquery side?

removing added django application from a database
I just posted another question: Django error on deleting a user in the admin interface But realized in that question the project /models it is complaining about I am going a different direction with.

Is it just a matter of removing all the data in models.py and then doing a new migration? -
