Installing

You must have the Mongo C drivers installed, see https://github.com/mongodb/mongo-c-driver.

Getting Started

require("Mongo.jl")

using Mongo

client = MongoClient()   # Defaults to MongoClient("localhost", 27017)

# Insert a few documents
insert(client, "test.people", { "name" => "Brian", "age" => 30, "hobbies" => {"surfing", "coding", "video games"}})
insert(client, "test.people", { "name" => "Lizzie", "age" => 30, "hobbies" => {"traveling", "crafts", "movies"}})
insert(client, "test.people", { "name" => "Adam", "age" => 31, "hobbies" => {"climbing", "cycling"}})

# Find Brian
obj = find_one(client, "test.people", { "name" => "Brian" })

# Change his age to 31
update(client, "test.people", { "_id" => obj["_id"] }, { "\$set" => { "age" => 31 }})

# Change everyone's age to 30
update(client, "test.people", Dict(), { "\$set" => { "age" => 30 }}, MULTI)

# Change Adam back to 31
update(client, "test.people", { "name" => "Adam" }, { "\$set" => { "age" => 31 }})

# Find everyone's name and age and display
fields = { "name" => 1, "age" => 1 }

cursor = find(client, "test.people", Dict(), fields)

for o in cursor
    println("Name: " * o["name"] * " / Age: " * string(o["age"]))  # Or simply, println(o)
end

# Remove Lizze
remove(client, "test.people", { "name" => "Lizzie" })

# Actually, let's just remove everyone
remove(client, "test.people", Dict())
