Great Video. Azure Function Python V2 Programming model has very limited videos other than just basic. I will greatly appreciate more videos' for advanced use cases.
if the function doesnt work and it keeps getting nothing, the solution might be going to your funtionApp on Azure, and go to environment variables , and then try to add the connection name as a key and the connection string of your storage account as a value , and it will work.
Thanks for the video, very nicely done! It did not work at first for me because I had to specify in my local.settings.json the connection string to AzureWebJobsStorage. Also, the path in function_app did not require the storage account name but only the blob container name. Which ended up to be "blob_container_name/{name}" (I wanted my function to get triggered no matter if I would receive a csv or not; otherwise it would have been "blob_container_name/{name}.csv"
Hi Pedro, I have a question, are you a Data Engineer? Also, thank you so much for the video. There isn't alot of Azure videos out there, but Azure for a Data Engineer perspective can be one of the best cloud platforms to use. Keep it up!
@@pytalista same here! I'm building a data pipeline that scraps pdf files from an email using logic app and function app. I am using HTTP trigger for function app, but its not the best one for it. The blob trigger is best so that when the pdf file lands in the container, it gets triggered
A blob trigger is an event driven action. So whenever a blob arrive at a particular location a function will be triggered. Service principle are to grant access to resources. So a blob trigger is independent of service principle. Seu you have a service principal that you want access to your storage account you can do that for sure. 👍🏻

this video is great. Can you also do a video talk about the output? I am using a blob trigger templet and process the blob in openai , but I have a problem to store the openai response into blob storage. I am appreciated if you do a video about handling the output. The Azure documentation is unclear.
Hi, if you want explicitly is easy. Just put the full blob name. I uploaded the code in the repository github.com/pedrojunqueira/PytalistaYT/blob/master/Python/storage_trigger/function_app.py
Could you please show in detail how you were able to create those records as new file in the blob storage and share your code, so I could try to imitate the process and take it from there. Thanks
@@pytalistaThank you. I'd really appreciate that. In my use case, I need Azure Function to fetch a file from blob storage, perform operations, save pdf pages as jpg, and then either rename the original file or save the renamed file in another folder on blob storage. I'm struggling with connecting to and writing back onto the blob storage, and the documentation hasn't been helpful.
Is there any specific reason why the blob size comes out as None everytime? I have a use case which extends blob trigger to call a search service on newly added/modified files, and I'm getting blob not found 404 error 😑 despite the blob being there in my container. Thank you for the video though, it confirmed I'm not doing something astronomically wrong 😂!
@@pytalista Oh yes, I had to implement custom logic for my use case, so the code was quite different. The storage account I was trying to access did not allow anonymous access and an incorrect request URL was being generated. All in all, Blob was not found. I was able to debug it. Your video set a great precedent, thank you for replying.
It is a very greate video. I was looking for very long time for a video like that. Thank you! My code works perfectly when i run it on Visual Studio. But it is not triggered on Azure. Is there any special thing I need to do more? Code is deployed on Azure. I can see the updated code on Azure. Connection strings in Environment Variables are correct. When I run code in Azure I get 202 response. But I get no logs. There are no invocations on Azure.
There is no question :). I have figured it out. My connection was connection="BlobStorageConnectionString" and i did not add it to Environments variables. Stupid error.
Hi @rosscortb you just need to change you small thing if the code instead of df.to_csv(f, index=False) you do a df.to_excel(f, index=False) Here is the code github.com/pedrojunqueira/load_table_data_lake/blob/master/load_data_to_folder.py look at line 89. Cheers
@@pytalista I've managed to get a function app that works for me. I have deployed and added it to a pipeline. It starts by copying an oracle query to csv and then the function app coverts it. When adding the function app to the pipeline, it asks for a method - Select API Method. I assume its Post but then it requires a body? Any ideas what to put here? thanks
@@rosscortb I need a bit more context. A POST request is usually when you want to change an object in your API. in the body you pass a "payload" in JSON format. I need to see the code to understand better. If you are using a blog trigger you do not need to put in a pipeline (you mean data factory?) it triggers when a new blob arrives in the folder you specify.
Hi, the video was very helpful for my POC. Thanks for that. can I know how to give multiple file patterns for example pdf and csv for the blob trigger to happend. I am trying this one but its not working. Moreover are there any restrictions on the file name patters as one of my blob name contains a space between the words and a curl brackets. I would really appreciate if you can provide the solution. Thanks in advance
Hi check the blob name patterns documentation. learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=python-v2%2Cisolated-process%2Cnodejs-v4&pivots=programming-language-python#blob-name-patterns
What you can do is get the file name and then apply different actions depending on the extension. like if it is .csv do this if it is such and such do that... cheers
@@SAHITHTHATIPALLI You can give one name that is going to get the blob name or a pattern. As I said. If you want to manage multiple use cases. Get the name of the incoming blob and handle it separately in a function.
When pressing F5 button it is giving error in launch json with exit code 1" The terminal process "/bin/bash '-c', '. . venv/bin/activate && func host start' " terminated with exit code 1

Well done Roxane. Great it worked in the end. Life of a programmer 🧑💻😀
You saved my life! thank you

Very informative video can you also make a same Blob trigger video using Azurite. It will be very helpful.
Sure. If you watch the durable function one it uses azurite
Actually it does not. Ok I will do a video.

@@antonietapintorebelo5020 Good job !
Great video, the only problem I have, after I have deployed my app it doesn't respond to new file uploaded to the blob
Have tested locally ? Did it work?
