I recently encountered a situation where I had an angular form with 9 fields and submitted it to the server using a post request. However, I realized that I had only filled in values for 8 fields while leaving one as null. Now, in a new component, I am working on a form with just 1 field and I need to send a put request to update this single field in the same 9-fields form. Can anyone offer guidance on how to approach this scenario? Any help is greatly appreciated. Thank you.
