I want to do the following.
If the fields are empty store the fields. If it is not empty update them. All this from one button

How my app works:
User login - show list of categories(each category is a collection in the database) - user fill in data and store the data - user comeback and want to update the data by pressing on the same button as the store button.

Hi Johnny,

It depends on your Database structure. Is there one, several or no records for each user in each collection?

No a row belong to a user. So each user have his own row.

Sorry i dont what i was reading when awnsering every user use every collection. And 1 row in every collection. A user start with no data.

So first time user create his row in a collection and after that he must just update the info.

Johnny,

You would need to create three services:

1. Reads data from collection and saves result true/false, depending on whether there is a record for the user or not.

2. Saves data from input fields to Database.

3. Updates the data.

   On Button click add the action - Invoke Service 1, then read the variable and run Service 2 or Service 3 depending on a variable value.

Ok I think I have it. Thank you!

Katya,

Just want to know something about the update.
I create a local variable "objectid" I then open "list_service" and in the response tab I connect the "_id" to that "objectid" variable.

Am I connecting the wrong id? My project is still shared.

Hi,

If you want update the records you should use update service. Could you clarify what exactly do you want to do?

Sorry for the late reply.

Ok so my app can Store and List the data. Now I do the update and I thought I did it correctly but there is 1 problem.

I do not know how to explain this but I try.

After I added the update service and link the fields I noticed that when I login with different users the same data display. It was working perfectly before I added the update service.
