Description
I've been testing the export model to script functionality. One models contains an Advanced Python Field Calculator.
The linebreaks in the Advanced Python Field Calculator python code cause the algorithm to fail.
2015-11-15T11:26:20 2 Uncaught error while executing algorithm Traceback (most recent call last): File "C:/OSGEO4~1/apps/qgis-dev/./python/plugins\\processing\\core\\GeoAlgorithm.py", line 230, in execute self.processAlgorithm(progress) File "C:/OSGEO4~1/apps/qgis-dev/./python/plugins\\processing\\script\\ScriptAlgorithm.py", line 298, in processAlgorithm exec((script), ns) File "<string>", line 8 outputs_QGISADVANCEDPYTHONFIELDCALCULATOR_1=processing.runalg('qgis:advancedpythonfieldcalculator', outputs_GRASSV.SPLIT.VERT_1['output'],'azimuth',0,3.0,0.0,None,'p1 = $geom.asPolyline()[0] ^ SyntaxError: EOL while scanning string literal
Here's the script that is generated:
##Tanaka Contours=name ##RASTERLAYER_DEM=raster ##NUMBER_ELEVATIONINTERVALS=number 10 ##tanakacontours=output vector outputs_GDALOGRCONTOUR_1=processing.runalg('gdalogr:contour', RASTERLAYER_DEM,NUMBER_ELEVATIONINTERVALS,'ELEV',None,None) outputs_GRASSV.SPLIT.VERT_1=processing.runalg('grass:v.split.vert', outputs_GDALOGRCONTOUR_1['OUTPUT_VECTOR'],2.0,None,-1.0,0.0001,0,None) outputs_QGISADVANCEDPYTHONFIELDCALCULATOR_1=processing.runalg('qgis:advancedpythonfieldcalculator', outputs_GRASSV.SPLIT.VERT_1['output'],'azimuth',0,3.0,0.0,None,'p1 = $geom.asPolyline()[0] p2 = $geom.asPolyline()[-1] a = p1.azimuth(p2) if a < 0: a += 360 value = a',tanakacontours)
