Access Mongo documents in a FUSE filesystem

This filesystem exposes mongo's structure, features and constrainst.

This is meant to ease the administration of a mongo database, it is NOT a general-purpose filesystem that uses Mongo for storage (look for GridFS if you want this)

# pip install mongofs

If you run into any problems, you may need to install fuse-python from your distributions repositories:

# apt-get install python-fuse

# mount mongodb://localhost ~/mongo -t mongofs

The filesystem is structured as /database/collection/field_name/field_value.json

If the field value is not unique, multiple field names/values pairs are stacked together: /database/collection/field1/value1/field2/value2/.../fieldN/valueN.json. This is equivalente to the mongo query {"field1":value1, "field2":value2, ..., "fieldN":valueN}.

Note values are JSON strings. Therefore, if your field type is a string, you will need to quote it. E.g., /db/collection/name/"John Smith".json. (Yes, it is a bit cumbersome)

$ mkdir ~/mongo/new_db                        #Create a database
$ rmdir ~/mongo/old_db                        #Remove a database
$ mv ~/mongo/old_db_name ~/mongo/new_db_name  #Rename a database

$ mkdir ~/mongo/db/new_collection                                   #Create a database
$ rmdir ~/mongo/db/old_collection                                   #Remove a database
$ mv ~/mongo/db/old_collection_name ~/mongo/db/new_collection_name  #Rename a database

$ cat ~/mongo/example_db/example_collection/foo/\"bar\".json
{
    "_id": {
        "$oid": "56297a874971f41c1b6e151b"
    }, 
    "foo": "bar", 
    "baz": 56, 
    "abc": {
        "a": "A", 
        "b": "B", 
        "c": "C"
    }
}

$ echo '{"a":"b"}' > ~/mongo/example_db/example_collection/_id/56.json 
$ cat ~/mongo/example_db/example_collection/_id/56.json
{
    "_id": 56, 
    "a": "b"
}

$ rm ~/mongo/example_db/example_collection/_id/56.json

Sometimes a human needs to be view or edit a Mongo document. And when humans are involved, a good UI helps a lot!

I have been using Robomongo for that. It is a fine UI, but it doesn't compare with being able to use my favorite $EDITOR.

When I realized I was copy-pasting between robomongo and my text editor all the time, I decided It was time to fix that!

• Read/Write documents using Mongo's Query Syntax
• Support for renaming filters and files
