This tool is used to create sample documents based upon a reference JSON document passed as a string on the command line or within a JSON file. For example, if we want to create 100 fictucious documents based upon this document schema:
{ 'Name' : 'some random string', 'Age' : some random integer 'Salary' : some random float }
python3 doc-gen.py -s '{"Name":"string","Age":123,"Salary":0.0}'
This will output 100 documents with the schema above to the console.
You can write the sample data to MongoDB by using the -c parameter to define the connection string, the -db parameter for database name and -col for collection as follows:
python3 doc-gen.py -s '{"Name":"string","Age":123,"Salary":0.0}' -c "mongodb+srv://YOUR CONNECTION STRING GOES HERE" -db "Sample" -col "SampleCollection"
You can omit the -s flag to write the default json sample schema.
| Flag | Description |
|---|---|
| -h | show help |
| -t | Total number of samples to create, default=100 |
| -c | MongoDB Connection string, omit to write samples to console |
| -db | Database to write samples |
| -col | Collection to write samples |
| -f | JSON file to load the example schema |
| -s | JSON sample provided as a string |
