I want to create an algorithm with the graphical modeler in QGIS 3.0.3 where i define one Vector Layer and a Vector Field from this Layer as my inputvariables. Then i want to access the field-values in the field calculator. For example: formula in fieldcalculator:
($area/1000000) * INPUT_FIELD
But this won't work. The fieldcalculator doesn't know or can't access the field values.
When i use an algorithm and define the INPUT_FIELD as an input-variable it works, but i can't access the field-values in the calculator.
How can i acess the field-values from my input Vector Field in the fieldcalculator?
