I have a csv file with the following columns:
table geometry field type typeName len precision
and my goal is to create a number of shp files programatically with PyQGIS.
My script stops after creating the first shp file.
Here's my code. Thanks in advance guys!
import sys
import re
import csv
from PyQt4.QtCore import *
from PyQt4.QtGui import *
reload(sys)
sys.setdefaultencoding('utf8')
final_list = []
with open(r"D:\Users\Ravi_narayanan\Documents\shpgen.csv", "rU") as s:
reader_tables = csv.DictReader(s,delimiter=';')
liste_tables = list(reader_tables)
l_tables = [i['table'] for i in liste_tables]
l_tables = set(l_tables)
for table in l_tables:
l1 = [line for line in liste_tables if line['table'] == table]
geometry = l1[1]['geometry']
layer_mem = QgsVectorLayer(geometry+"?crs=epsg:2154",table,"memory")
QgsVectorFileWriter.writeAsVectorFormat(layer_mem,r"D:\setupCAPFT2.00\{}.shp".format(table),"utf-8",None,"ESRI Shapefile",False)
layer_path = "D:\{}.shp".format(table)
shp = QgsVectorLayer(layer_path,table,'ogr')
pr = shp.dataProvider()
shp.startEditing()
for field in l1:
if field['type'] != 'Double':
pr.addAttributes([QgsField(field['field'],getattr(QVariant,field['type']),field['typeName'],int(field['len']))])
else:
pr.addAttributes([QgsField(field['field'],getattr(QVariant,field['type']),field['typeName'],int(field['len']),int(field['precision']))])
shp.updateFields()
shp.commitChanges()
shp.stopEditing()
del layer_mem,shp,pr
