SQL generator to populate a test database based on your own schema.. and some decorators.
Note: This was tested against python 2.7 so YMMV. If you have an issue, submit it.
populace.py [-h] [-v] -i INPUT_FILE [-o OUTPUT_FILE] [-r RECORDS]
Note: The .sql file created will require that your database user have the following permissions:
If you already have a schema you'd like to use for your tables, you're golden. All you need to do next is add a few decorators. Easy-peasy!
Okay, let's say you have this schema(1):
CREATE TABLE Users ( id int auto_increment, email varchar(60) not null unique, password varchar(128) not null, firstname varchar(20) not null, joined_on datetime not null, primary key (id) );
Now that's a sexy schema, but you're looking for the meat and potatoes. Let's eat!
CREATE TABLE Users ( id int auto_increment, email varchar(60) not null unique @email, password varchar(128) not null @password, firstname varchar(20) not null @first_name, joined_on datetime not null @datetime, primary key (id) );
And just like that we've given the app enough to generate our SQL! Now you only need run the script:
populace.py -i schema.sql -o ready.sql -r 30
Bam! You have an SQL file that's ready to be imported into your database.
(1) The example uses MySQL, but you're free to use whatever relational database you want.
Now here's the nifty part. Those decorators that you used in your schema.. they're not builtin. "Wait. What?!" Yep, you heard me right. Those decorators are dynamically generated from the text files included in the
lists folder. When you see one that you want, simply add @filename (sans-extension) to your schema.
Are you wondering if it's possible to make your own decorators? If so, I have a short answer for you: YES! "Well, well. How do I go about that, good sir?" By following these simple guidelines:
- Each value must be on its own line
- Filenames cannot contain spaces
If you're still confused, look at the files in the
There is another caveat: if the number of records you want is greater than the number of values in that file you will get slapped with an exception. Since that's the case I would recommend adding at least 1000 values to your decorator file.
records > custom_values = exception
