5 min readTo pass the db:session object to a Celery task in FastAPI, you can achieve this by first creating a dependency which provides the database session to your Celery task.Within your FastAPI application, you can create a dependency function that creates a new session and yields it to your Celery task. In your Celery task function, you can then accept the session as an argument and perform database operations within the task.

6 min readTo convert spool contents with PowerShell, you can use the Get-Content cmdlet to read the content of a file, which can then be manipulated using various PowerShell commands. You can use regular expressions or string manipulation functions to extract specific data from the spool contents, and then use Set-Content cmdlet to write the modified content to a new file.
-
7 min readTo restrict the content-type in FastAPI request header, you can use the Depends function from the fastapi.security module along with the Security object. By defining a function that checks and enforces the desired content-type and using it as a dependency in your endpoint, you can restrict the content-type that the endpoint will accept.For example, you can create a function that checks the content-type in the request header and raises an error if it does not match the expected type.

3 min readTo run a command line argument using a PowerShell script, you can use the syntax: param( [string]$argument ) Write-Host "Argument passed: $argument" In this script, the param keyword is used to define a parameter named $argument which will hold the value of the command line argument. The Write-Host cmdlet is used to display the value of the argument passed to the script.

8 min readTo run FastAPI on Apache2, you can use a reverse proxy setup. This means that Apache2 will act as a gateway to forward requests to your FastAPI application. You can do this by configuring the Apache Virtual Host file to pass requests to your FastAPI application using a ProxyPass directive. Make sure to have mod_proxy enabled in your Apache server. Additionally, you may need to set up a custom port for your FastAPI application and configure Apache to listen on that port.
-
2 min readTo check if a string exists in a file using PowerShell, you can use the Select-String cmdlet. You can specify the file path and the string you are looking for as parameters. If the string is found in the file, the cmdlet will return the line where the string is located. You can also use the -Quiet parameter to return a Boolean value indicating whether the string was found or not. You can save the result in a variable and then check its value to determine if the string exists in the file.
-
5 min readIn FastAPI, you can perform partial updates by making a PATCH request to the desired endpoint with the specific fields that you want to update in the request body. This allows you to update only certain fields of a resource without having to send the entire object.To implement partial updates in FastAPI, you can use the Pydantic library to define your data models and schemas, which will automatically validate and parse the incoming request data.

4 min readYou can name Python sessions from a PowerShell script by using the "Start-Process" cmdlet to launch the Python interpreter. You can specify a name for the process using the "-Name" parameter. For example, you can run the following command in a PowerShell script: Start-Process python -ArgumentList "your_script.py" -Name "MyPythonSession" This will launch a Python session with the name "MyPythonSession" and run the specified Python script.
-
4 min readIn FastAPI, you can cancel a previous request by using the standard Python asyncio module to create a task and then cancelling that task before it completes.Here is an example of how you can cancel a previous request in FastAPI: from fastapi import FastAPI import asyncio app = FastAPI() # Store the task object in a global variable current_task = None @app.

8 min readTo change a foreach loop to a for loop in PowerShell, you can use the for keyword followed by the initialization, condition, and iteration statements within parentheses. For example, if you have a foreach loop that iterates over an array: $fruits = @("apple", "banana", "orange") foreach ($fruit in $fruits) { Write-Output $fruit } You can change it to a for loop like this: $fruits = @("apple", "banana", "orange") for ($i = 0; $i -lt $fruits.
-
5 min readTo redirect with an OAuth token return in FastAPI, you can use the RequestRedirect class from the fastapi.responses module. After receiving the OAuth token in your FastAPI route handler, you can create a new Response object with the token as a parameter and then return a RequestRedirect response with the desired redirect URL and the newly created response object.Here's an example: from fastapi import FastAPI from fastapi.responses import RequestRedirect app = FastAPI() @app.
