Source code setup for Azure Functions and run

Question

Hi

I have a function app which has two functions and they both work with Http Triggers. This was developed by someone in the past. I am new to the Azure Function App Technology.

I am unable to change any code through the Azure portal as it says "This function has been edited through an external editor. Portal editing is disabled." Following is the screenshot.

Now I connected through Visual Studio Code and still I am unable to change anything and when I try to change it says "Cannot edit in read-only editor" . How do I edit this ?

I do not have a source control setting for this function app. How do I enable source control through Azure Devops. I have a repo in Devops specifically for these functions.

Please guide me on this.

I checked this in the Github project for the Azure functions extension for vscode. This issue indicates editing of published functions is not supported in visual studio code. So that is why it is only shown in read only mode.

You can enable editing of the function in the Azure Portal by going to the Configuration blade under the Settings menu in your function app and add or edit a variable named FUNCTION_APP_EDIT_MODE and give it a value of readwrite to enable editing from the portal.

If you want the published function app code it is available in the storage account tied to the App. TO find the name of the storage account, again on the Configuration blade, click the WEBSITE_CONTENTAZUREFILECONNECTIONSTRING to find the connection string. In that string the AccountName indicates the name of the storage account holding the files.

Hi @Krishnamohan Nadimpalli ,

Thanks for reaching out to Q&A forum.

When an azure function is deployed from Visual studio/Visual code or any other deployment pipeline, it becomes pre-compiled code and it cannot be edited in the portal. Please note that you can only edit the code in portal when it is developed in portal. It appears that your python function was deployed from VS code so you are not able to edit in the portal. Only way to edit is to make changes to the VS code functions project and deploy again.

Since you already have this repository in Azure devops, you can create a new build and release pipeline to deploy to Azure functions. Please follow any one of the below articles for deployment
