Pass variable Layer in function parameters in PyQGIS

Question

I want to pass this layer = self.iface.activeLayer() into a function import_meta(self, layer) to be used like a layer object dpr = layer.dataProvider()

But when I run the script I get error AttributeError: 'xdr_ImportMeta' object has no attribute 'dataProvider' dpr = layer.dataProvider()

I guess the variable's type layer doesn't pass as I want. This is the code:

def import_meta(self, layer):
 dpr = layer.dataProvider()
def run(self):
 layer = self.iface.activeLayer()
 self.import_meta(self, layer)

Answer 1

Simply put, when you call a function (defined in a class) in own class, you don't need to use self argument. Python implicitly passes self as first argument to the function.

So, try to change self.import_meta(self, layer) into self.import_meta(layer).
