Django Rest Framework. How can I serialize model name and instance values instead of content_type and object_id?
I believe there should be a straightforward way to do this, but I can't figure it out. Appreciate some help. In a model like this: class Item(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') def __str__(self): return str(self.content_type) + str(self.content_object) I serialized it like that: class CaseDetailSerializer(serializers.ModelSerializer): class Meta: model = Item fields = '__all__' Which returns me: [ { "id": 1, "object_id": 35, "content_type": 29 }, { "id": 2, "object_id": 36, "content_type": 31 } ] And I would like to have something like that: [ { "id": 1, "object_id": "A value from the instance such as name, instead of the ID", "content_type": "The name of the model, or even better, the verbose name" }, { "id": 2, "object_id": "A value from the instance such as name, instead of the ID", "content_type": "The name of the model, or even better, the verbose name" } ] SlugRelatedField seems to be the way forward, but I can make it work. Adding this to the serializer is a good stepforward. content_type = serializers.SlugRelatedField( queryset=ContentType.objects.all(), slug_field='model') However, for the object_id is not so clear to me how to query since the model is not always the same. Thanks in advance, … -
Too many connections to the DB in Heroku-postgress
In my code I can't find an error, but something wrong. Every few seconds in the heroku-postgresql there is +1 connection. The one place, where it can happens is: def dis_online_users(): date_time_now = datetime.datetime.utcnow() users = Users.objects.filter(when_online__lt=date_time_now, is_online=True) for user in users: user.is_online = False user.save() return True def start_background(): scheduler = BackgroundScheduler() scheduler.add_job(dis_online_users, 'interval', seconds=60) scheduler.add_job(remove_deleted_messages, 'interval', hours=48) scheduler.add_job(delete_null_chats, 'interval', hours=48) scheduler.start() start_background() But I can't understand what's wrong there. Can you? -
Make second request after first is done, csrf Django issue
I have a Redux app, and there is a component SalaryComponent where in its constructor I call an action creator that makes a request to the server and then dispatches an action, so the state is updated. I need to make the second request to the server after the first one is finished since I need to get some data from the first one to do the second. How would you approach the problem? Update I was able to get the second ajax called in the constructor like this: props.loadSalary(salary_id).then(() => { props.loadData(salary_id) }) I verified that loadData gets its argument salary_id correctly. But then I am getting the error Forbidden (CSRF token missing or incorrect.). The first request does not cause CSRF error, but the second somehow does. The first request is GET, but second is POST. Ultimately I solved it by using @csrf_exempt on the Django side as a decorator to the method I was using to process the second request. Another way is to get CSRF token in the browser and use it on the backend. -
Best way to have a server that only receives data?
I have a local database that I want users to be able to add to. I don't want my database to be on the server. I would want users to send data to my server which I could then look at and add accordingly to my local database. The user does not need to be notified. What would be the best way to implement this server that users can send information to? I'm basically trying to think of a way to have a secure server that only receives information. How do I create a receive-only data server? I'm not really sure how to go about implementing this. -

Is there a Python Database Framework? (Like a web framework without the web)
Is there such a thing as a Python Database Framework? I want all the things a web framework has (pluggable objection creation and management, authentication, authorization, robust error handling, etc.), just without the web. My previous experience is creating Django REST Frameworks that communicate via REST (i.e. microservices), but I'm on a project where the lead is against that, and wants each service to live and in the same Django application and call each other directly, and I'm at a loss. Is there a framework for interacting with databases in a similar way as DRF, but oriented around returning database objects instead of web responses? Just using Django's ORM doesn't like that, because a lot of the nice checks and common actions are baked into the views. Thanks for your thought! -
What's the best way to perform actions before a Model.save() using Django?
I'm using Django-Rest-Framework(ViewSet approach) on my project interacting with a React app. So, I'm not using Django admin nor Django forms. My project's structure is: 1. View 2. Serializer 3. Model What I need to do is to perform actions before models method calls: 1. Insert the request.user on a Model field. 2. Start a printer process after a Model.save() 3.... I have read a lot about django-way to do on Django.docs and there, the things seems to be showed for a Django-Admin like project, wich is not my case. By other hand, by reading the Stack's answers about in other topics, the way to do seems to be like: "It will work, but, It's not the right way to do that". According to Django's documentation, the best way to perform that supposed to be by using a new file, called admin.py, where I would to register actions binding to a Model wich could support save, delete, etc, but, it's not clear if this approach is to do that or only for provide a Django-Admin way to perform an action. # app/models.py from django.db import models from django.contrib.auth.models import User class Post(models.Model): user = models.ForeignKey(User) content = models.TextField() class Comment(models.Model): … -

Django: Encoding problem on production environment
The data is stored in a dataframe as "S\u00c3o Miguel", but the data is returned from template as "S%C3o Miguel", and Python can't find it on the dictionary. How can I solve this? Hi guys, I developed an application that gets data (as well as the labels) from the database and plots them on charts using the Highcharts library. When the user clicks on one of the bars of the charts, the label of it is sent back to the server, which returns some values. The problem is: when the data is first loaded from the database, it is stored in memory in a dataframe, where "S\u00c3o Miguel" is one of the values, but when the user clicks on a chart and the JQuery request is made to the server, it is sent back as "S%C3o Miguel". Due to this, the code can't find this key on the dataframe in the memory. I've tried to encode the string as UTF-8 with encodeuricomponent on JavaScript prior to sending it back to the server, but no sucess. The template already has the tag. def getFromDatabase(): [...] wfarm_names = pd.read_sql(query, engine) #Gets the data from the database return (list(wfarm_names['CL_NAME'].unique())) #Returns a list with … -
Unexplained python "function-redefined" error vscode on empty line
I cannot get rid of a function redefined error on the first line of a specific module, unless I uninstall the python extension from vscode.

How to serve static folder which is located in network drive using nginx
I have a network drive mounted on my redhat server 7 using /etc/fstab. We have a folder called "FolderA" under this folder we have subfolders. We need to serve this folder as static folder location using nginx. It seems not working. We have another folder called static which is present on the same filesystem. It is working properly when served with nginx. The requirement is to serve both folders if not found in one folder find it in other folder. # location /static/ { # autoindex on; # root /www/AutomationServices/static; # try_files $uri $uri/ @secondStatic; # } # location /storage/ { # root /storage/Investigator_Validator; # } # location @secondStatic{ # root /storage/Investigator_Validator; # } location ~ ^/static/(.*)$ { root /; autoindex on; try_files /www/AutomationServices/static/$1 /storage/Investigato r_Validator/$1 =404; } The final result is like to serve two folders as static locations using nginx webserver. One folder is located in network drive and one is located in the filesystem -

Internal Server Error 500 when deploying Django Application to Elastic Beanstalk
I followed meticulously the official AWS guide to deploy a Django App to Elastic Beanstalk (https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html) for a school project. It is working locally, but when I try to deploy it shows a 500 Error message. I went through many adjustments in my code but they don't seem effective. The AWS dashboard shows one warning that says: Environment health has transitioned from OK to Warning. 100% of the requests are failing with HTTP 5xx. Could it be a timezone problem as I am currently in Europe? I tried to change debug mode from true to false, but I don't think that's the problem. the I truly do not understand why it's not working, I never got an error in the execution in the terminal and it always deployed everything correctly.
