Use @user_account_name in Roam

[JAsPCn]

Hi.

I´m trying to use the standard QGIS function @user_account_name in Roam 2.7.1. But the syntax [% @user_account_name %] in the Expression or Expression String Builder in the Form Design is not working for me.

In QGIS 2.18, I can see the function is available, you can use it for example in a label. And the same label is visible in Roam.

Is there an alternate syntax for this? If it's not implemented in Roam, can it be accessed with the functions eval or val? How? If it is not possible either, can I expose the value in a plugin, and access the value from inside Roam? What syntax should I need to use?

Probably not the best way to do it but I got this code from some where years ago. It grabs the Windows username. I put this at the end of the load function in form.py:

        if self.boundwidgets.get('created_user')!=None:
            import getpass
            self.boundwidgets['created_user'].setvalue(getpass.getuser())
        pass

Hey @bluedogit, thats just an indenting issue. If you haven’t used python before (the language the form is written in) you might want to read this https://docs.python.org/2.0/ref/indentation.html https://docs.python.org/2.0/ref/indentation.html . Basically python code needs to be consistently indented.

Once you get the indents correct it should work. Attached is a screen show how mine looks.

Thanks @bwragg, I knew about the indenting but it was throwing an exception. Turned out the indenting needed to be whitespaces not tabs. I changed them over and off it went.

Top three line don't work but the bottom three do. Once I changed it off it went. Thanks for pointing my in the right direction about doing things on load. [image: image.png]
