我需要一个答案,现在我正在执行此命令:
python manage.py loaddata app/myapp/fixtures/* --settings=setting.develop
这工作正常,但现在我想做同样的命令,但忽略或滑动app / myapp / fixtures /中的一个简单文件,所以我不想为每个夹具里面写一个loaddata,我只想做一个命令和使用类似–exclude或–ignore或某种方式在一行中执行此操作并保持/ *再次使用其中的所有文件.
提前致谢!
最佳答案 写
your own management command in Django很简单;并继承自Django的loaddata命令使其变得微不足道:
excluding_loaddata.py
from optparse import make_option
from django.core.management.commands.loaddata import Command as LoadDataCommand
class Command(LoadDataCommand):
option_list = LoadDataCommand.option_list + (
make_option('-e', '--exclude', action='append',
help='Exclude given fixture/s from being loaded'),
)
def handle(self, *fixture_labels, **options):
self.exclude = options.get('exclude')
return super(Command, self).handle(*fixture_labels, **options)
def find_fixtures(self, *args, **kwargs):
updated_fixtures = []
fixture_files = super(Command, self).find_fixtures(*args, **kwargs)
for fixture_file in fixture_files:
file, directory, name = fixture_file
# exclude a matched file path, directory or name (filename without extension)
if file in self.exclude or directory in self.exclude or name in self.exclude:
if self.verbosity >= 1:
self.stdout.write('Fixture skipped (excluded: %s, matches %s)' %
(self.exclude, [file, directory, name]))
else:
updated_fixtures.append(fixture_file)
return updated_fixtures
用法:
$python manage.py excluding_loaddata app/fixtures/* -e not_this_fixture
