Open raster referenced in attribute column of vector layer

Question

I have a polygon layer. One of the columns holds an absolute path to a (georeferenced) raster. Is there a way to (programmatically) open this raster in QGIS and add it to the map canvas?

This will add the first raster (in my example the only one) from the vector layers attribute table:
import os 
vector_layer = QgsProject.instance().mapLayersByName('vl')[0] #Change
field_with_path = 'abspath' #Change

rasterpath = [f[field_with_path] for f in vector_layer.getFeatures()][0] #[0] for the first feature
rlayer = iface.addRasterLayer(rasterpath,os.path.basename(rasterpath)[:-4],"gdal")
