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.

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.

4 min readTo return a list using router in FastAPI, you can create a new route in your FastAPI application and use the Response class from the fastapi.responses module to return a list as the response. You can use the json method of the Response class to serialize the list into a JSON format and return it to the client.Here's an example of how you can return a list using a router in FastAPI: from fastapi import FastAPI, Response app = FastAPI() @app.

3 min readTo write processes to an XML file using PowerShell, you can use the Export-Clixml command. This command allows you to serialize objects to an XML file. You can first create an object representing the processes you want to write to the XML file, then use the Export-Clixml command to write that object to a specified XML file. This can be useful for saving information about processes running on a system for later analysis or reporting.

5 min readIn FastAPI, you can validate the request body using Pydantic models. Pydantic is a data validation library that can be used with FastAPI to define the shape of request data and automatically validate it.To validate the request body in FastAPI, you need to create a Pydantic model that represents the structure of the request data. You can then use this model as a parameter type in your FastAPI route function.

6 min readIn PowerShell, you can loop through two arrays simultaneously using a for loop. You can iterate through both arrays by their index positions and perform operations based on the elements of each array at the corresponding index. Here's an example of how you can loop through two arrays in PowerShell: $firstArray = @("apple", "banana", "cherry") $secondArray = @(1, 2, 3) for ($i = 0; $i -lt $firstArray.

4 min readTo run a FastAPI app on multiple ports, you can use the uvicorn server with the --port flag followed by the desired port number. You can specify multiple ports by running multiple instances of the uvicorn server with different port numbers. This allows you to have your FastAPI app running on multiple ports simultaneously, serving different clients or managing different functionalities.
