Updating single fields and other random Firebase REST API tips

Community guide
#1

Dear amazing people,

I have been using Appgyver for exactly a month today, and while it has been hard for me as a non-tech newbie, I learnt quite a ton. I have collated micro documentation of the major tips I learnt on the way and thought it might be helpful for other Firebase backend users.

Tips currently cut across Authentication, updating documents fields and many more. I highly encourage collaboration to add to this list of tips, and I hope you find these as useful as I did.

Ooh, and if you find another lost copy of this on the forum kindly alert me, I had tried to upload this earlier and had bad internet connection so I don’t know here that went.

Cheers.

I tried creating a documentId with post and it worked great, the only thing is I had to write the new document ID inside the URL. Is there a way that we can have an input value fromfrom an input field on the UI that could change the URL’s documentId?

#5

That should be possible via using a page variable :slight_smile: If you are unsure how to work with variables, check out these videos: Core Lesson 1 - Variables & Formulas - AppGyver

How do we form the update mask to edit a field in a nested array or map or to add a new item to a nested array? I have searched all the firebase docs and can find nothing about it.
