Connecting Django Application in One Docker Container to MySQL in Another Container
Title: "Connecting Django Application in One Docker Container to MySQL in Another Container" I have a setup with two Docker containers: mysql-container: This container runs a MySQL image. my-django-container: It hosts a functional Django application. My objective is to establish a connection between the Django application running in my-django-container and the MySQL server in mysql-container. However, I'm encountering a database connection error: django.db.utils.OperationalError: (2002, "Can't connect to server on '36.253.8.13' (115)") Here are my Django settings for the database: "default": { "ENGINE": "django.db.backends.mysql", "NAME": "name", "USER": "username", "PASSWORD": "password", "HOST": "172.18.0.2", # What should I put here? The actual IP of the server `36.253.8.13` or the IP of the SQL container `172.18.0.2`? "PORT": "3306", # Is this the default port for SQL? } I've also placed both containers in the same Docker network, and I can confirm that both containers are visible when I inspect the network using the docker network inspect command. As a Docker novice, I would greatly appreciate any assistance in resolving this issue. -
How to use or work with fileshare.aio library?
I have been trying to implement the azure.storage.fileshare.aio Python SDK to upload files to my Azure File Share. I tried using the asyncio class and its functions to implement the directory_client.upload_file() function, that seems to be not working as expected and the control directly jumps to the return statement. I have provided the code snippet below. Please excuse any of the knowledge gap regarding async implementation, I have just started off with it. def some_other_func(): ..... directory_client = get_directory_client_aio(base_url=file_dir_url) response = asyncio.run(save(directory_client, new_file_with_changes, tasks=tasks)) ..... return response async def save(directory_client, new_file_with_changes, tasks : list): async with directory_client: tasks.append(asyncio.create_task(directory_client.upload_file(file_nam=new_file_with_changes.name, data=new_file_with_changes, length=new_file_with_changes.size))) asyncio.gather(*tasks) return Response.send_response(code=55) It will be appreciated if I get some assistance, Do's and Don'ts on the same. Thank you. -
Django and React authentication with Axios failing
I am building a web app with React and Django (frontend and backend resp.) and I am struggling to do user authentication. The urls in Django in my setup are basic, I will commit them for now. The views should be straightforward (feel free to suggest a more idiomatic approach as I am struggling with getting the right request response flow) basically, you can get a user with /users/int:id/ which returns either a private or public user object depending on whether the id is also the id of the authenticated user, login sends the id of the current user when successful. The issue I have is that login on it's own works just fine, though, when I refresh the page, react seems to have forgotten that the user was logged, it would be really annoying to ask the user to log in every time the page reloads. Therefor I made the authenticate view (and url users/authenticate/) which is supposed to return the private user object based on the session id. It is at this stage that things go wrong, the view does not recognise the user as authenticated (i.e., is_authenticated would fail). Some of the react: Home.js export const Home … -

How can I connect the mayanedms api to my django project?
I would like to connect MayanEdms api to my Django project. Note that mayan is running on different port from my Django container (both are running Docker). The problem I'm having is because, if I navigate to the api link, it works for me, but if I do it through code it doesn't. I don't know why that is? I attach below the error that I get both in the browser and in the command console. I also attach the function that should connect to the API. What I want this function to do is to list all the documents that arrive to my email (it is read with MayanEdms). Once the documents are saved in Mayan, I want to show the information of the emails, including the attached files, in the independent interface that I have made with django. views.py: @login_required def f_facturaspendientes(request): # URL de tu API externa que proporciona las facturas pendientes api_url = 'http://127.0.0.1/api/v4/documents/' # Datos de autenticación auth = ('admin', 'jehK4XvBGp') # Realiza una solicitud GET a la API con autenticación response = requests.get(api_url, auth=auth) # Verifica si la solicitud fue exitosa if response.status_code == 200: data = response.json() # Convierte la respuesta JSON en … -

Django: convert dropdowns created with Html pages in Django forms (project already working)
I have a small fully functional project where there are 3 dropdowns, however created with manual Html pages.

Creating a Custom Choices Field in Django Model
I'm working on a Django project and need to implement a charfield field "Custom" in the dropdown menu in the UserProfile model. The requirements are as follows: Users should be able to select their gender from predefined options (Male or Female). Additionally, there should be an option to select "Custom" if the user's gender is not represented by the predefined options. If a user selects "Custom," a text field should appear, allowing them to enter their gender description. I've already created the UserProfile model with predefined gender choices, but I'm not sure how to dynamically show or hide the text field based on the user's selection of "Custom." Note: I want this to be done in both Django Admin and DRF API. Feature should look like this: a screenshot of a custom field taken from Instagram Here's my UserProfile model: class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) FEMALE = 'FEMALE' MALE = 'MALE' CUSTOM = 'CUSTOM' NONE = 'NONE' GENDER = [ (FEMALE, "Female"), (MALE, "Male"), (CUSTOM, "Custom"), (NONE, "Prefer not to say"), ] gender = models.CharField( max_length=20, choices=GENDER, default=NONE, ) custom_gender = models.CharField( max_length=255, blank=True, # Allow it to be optional null=True, # Allow it to be null ) …
