This is just a very basic tool for creating mongo migration scripts.
Usage is fairly simple, just:
python migrate.py create Brief Description Here
This will generate a script with the description in the name, as well as a timestamp when it was created (to mitigate name collisions, and help order running of the scripts)
The generated file is Javascript, with a small amount of boiler plate code included.
Running all scripts that have not yet been run is easy
python migrate.py update
If you want to run the scripts on a a specific host, use the -h flag when running update like so
python migrate.py update -h example.com
Similarly if you wish to change the port use -p
python migrate.py update -p 30001
By default these values will be 'localhost' and 27017 respectively.
There is also an included include.js file which by default is included in all the scripts.
You can put whatever utility functions you wish in here. I've included a function i(variable), which converts a number to be an integer for Mongo (because Javascript doesn't have integers by default)
The tool keeps track of which migrations have been ran using a special database 'dev_db'.
If you want to change this, just edit the code, perhaps in future i'll add a flag for update to change this.
Also, this assumes all files are in the same directory, so if you want to add other non-related files, they'll need to be added to the list of ignored files. See the get_files function in migrate.py.
Up to date version is in requirements.txt
In short the only external dependency you'll need is PyMongo.
