Environment Variables

Submitted on ‎07-26-2018 11:55 AM Submitted by Advocate I on ‎07-26-2018 11:55 AM
An Environment should be able to have some base variables so apps can reference variables that might be different based off the environment that they are deployed in.  Or at least be able to tell what environemtn they are being run from so that those configuration varibles can be referenced from some table somewhere else.    We use a 4 teir deployment structure for all all our software and as such we have 4 different lanes for all our data sources.  When we develop the app it is done pointing to the dev lanes and everything is nice but the second we try to puch the app to test things get messy.  Any static hyperlinks or data sources need to be pointed to the test lanes.  It would be nice to have environment variables that don't require me to replicate everything to the CDS (more money and more brittle).  An app should be able to reference the base variables for the environment that they are deployed in.  This would make deploying through the 4 tier structure seemless. ...

Define original variable

Submitted on ‎07-30-2017 05:38 PM Submitted by Community Champion on ‎07-30-2017 05:38 PM
Link 1: https://powerusers.microsoft.com/t5/PowerApps-Forum/Sudden-err-but-no-dev-changes-made-Types-of-the-specified/m-p/47352#M19808   Link 2: https://powerusers.microsoft.com/t5/PowerApps-Ideas/Disable-check-for-errors/idi-p/45075   PowerApps seems to be confused with variable definitions. In Link 1, users of PA are noting that their navigation formulas are not working because the variable passed is encountering errors even though they had not edited the app. In Link 2, I reported that PA slows down when you are in the middle of typing a formula for an existing variable. Both problems have to do with the definition of a variable. It is not clear to us how PowerApps prioritizes definitions of variables--is there a hierarchy we can view?   I am suggesting that there be a location in PA where you could define a variable and the kind of data it is validated for. When typing formulas, PA would check against that original definition as a priority. Uses of the variable that match that original definition will be okay while anything that does not match the original definition would appear with the yellow sign.    So if you are in the middle of typing a formula: Set(variable, tr...) and the variable already exists elsewhere for taking boolean values, you would normally break every control that references the variable since they no longer think it takes boolean values. If you have an original definition that takes precedence, everything that relies on the variable would not have yellow error signs; only the most recent formula that doesn't match the original definition would have the error.   I predict that this would resolve performance issues described in Link 2 since the original definition would remain strong. I think it would also avoid issues with passing variables between screens as described in Link 1 (though I still recommend Set() instead of passing variables).   Is this doable? What is the existing hierarchy for which definition of a variable is prioritized? ... View more
