Django 1.6：如何忽略python manage.py loaddata中的一个fixture？

2024年1月17日 219次阅读

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
