python - How to import model in Django -


i want execute python file want check if there new rows in csv file. if there new rows, want add them database.

the project tree follows:

enter image description here

thus, file want execute check_relations.py inside relations folder.

check_relations.py follows:

from master.models import traxiorelations  open('autoi_relaties.csv', 'rb') tr:     traxio_relations = tr.readlines()  line in traxio_relations:     number = line.split(';')[0]     number_exists = traxiorelations.objects.filter(number=number)     print(number_exists)

the model traxiorelations inside models.py in master folder.

when run python check_relations.py error 

traceback (most recent call last):   file "check_relations.py", line 3, in <module>     master.models import traxiorelations importerror: no module named master.models

what doing wrong? how can import model inside check_relations.py file?

i think usable way create commands

for example in master catalog:

master /     management /         __init__.py         commands /             __init__.py             check_relations.py

in check_relations.py

from django.core.management.base import basecommand master.models import traxiorelations  class command(basecommand):     = 'check_relations file data'      def handle(self, *args, **options):          open('autoi_relaties.csv', 'rb') tr:             traxio_relations = tr.readlines()          line in traxio_relations:             number = line.split(';')[0]             number_exists = traxiorelations.objects.filter(number=number)             print(number_exists)

! don't forget change path file autoi_relaties.csv or put new dir

and can run in shell:

./manage.py check_relations

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
