添加外键异常使用imdbpy
问题描述:
我试图IMDB数据加载到使用IMDBPY 5.1 mysql数据库IMDB的数据加载到MySQL时抓住。 但是我最终总是遇到以下问题。我需要在模式中拥有完整的主键+外键约束。任何人都可以给我一些提示,说明可能的原因是什么?是添加外键异常使用imdbpy

我使用的命令如下
1)安装所有所需的软件包。
sudo apt-get install -y gcc python python-dev libssl-dev libxml2-dev libxslt1-dev zlib1g-dev python-setuptools python-pip
easy_install -U SQLObject
pip install MySQL-python
2)安装IMDBPY。
cd [IMDBPY_parent_directory]
wget http://prdownloads.sourceforge.net/imdbpy/IMDbPY-5.1.tar.gz
tar -xzf IMDbPY-5.1.tar.gz
cd IMDbPY-5.1
python setup.py install
3)在MySQL中,创建一个数据库 “IMDB”,并授予所有的权限为 “用户”,密码为 “密码”。
CREATE DATABASE imdb;
GRANT ALL PRIVILEGES ON imdb.* TO 'user'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
4)下载所有IMDB数据。
mkdir [imdb_data_directory]
cd [imdb_data_directory]
wget -r --accept="*.gz" --no-directories --no-host-directories --level 1 ftp://ftp.fu-berlin.de/pub/misc/movies/database/
5)将IMDB数据加载到mysql。
cd [IMDBPY_parent_directory]/IMDbPY-5.1/bin
python imdbpy2sql.py -d [imdb_data_directory] -u
'mysql://user:[email protected]/imdb'
我的设置是:
- 蟒蛇:2.7
- MySQL的:5.7
- 的Ubuntu 16.04
我也试过在MacOS 10.12 + MYSQL 5.7 + Python 2.7版和有同样的问题。
要达维德的建议使用的SQLAlchemy代替的SQLObject的:
我试图SQLAlchemy的使用下面的命令:
python imdbpy2sql.py -d [imdb_file_directory] -o sqlalchemy -u 'mysql://user:[email protected]/imdb?charset=utf8&local_infile=1'
我得到了下面的错误。
Traceback (most recent call last):
File "imdbpy2sql.py", line 538, in <module>
conn = setConnection(URI, DB_TABLES)
File "/Library/Python/2.7/site-packages/IMDbPY-5.1-py2.7-macosx-10.12-intel.egg/imdb/parser/sql/alchemyadapter.py", line 489, in setConnection
engine = create_engine(uri, **params)

engineclass.__name__))
TypeError: Invalid argument(s) 'local_infile' sent to create_engine(), using configuration MySQLDialect_mysqldb/QueuePool/Engine. Please check that the keyword arguments are appropriate for this combination of components.
我使用的是sqlalchemy 1.1.8版本。当我切换到sqlalchemy版本0.5时,我收到了同样的错误。当我切换到SQLAlchemy的0.4,我收到此错误:
Traceback (most recent call last):
File "imdbpy2sql.py", line 323, in <module>
from imdb.parser.sql.alchemyadapter import getDBTables, setConnection
File "/Library/Python/2.7/site-packages/IMDbPY-5.1-py2.7-macosx-10.12-intel.egg/imdb/parser/sql/alchemyadapter.py", line 54, in <module>
UNICODECOL: UnicodeText,
NameError: name 'UnicodeText' is not defined
我有没有指定“local_infile”错了吗?
答
这是最有可能在代码中的错误。
作为一种变通方法,请尝试使用替代的SQLObject SQLAlchemy的。 尝试安装它,使用它加入“-o SQLAlchemy的”(不含引号),以imdbpy2sql.py的命令行选项。
