I\'m successfully using MongoMapper\'s built-in support for atomic \"$push\" and \"$set\", but can\'t figure out \"$pull\"
I am getting multiple similar JSON object from a remote site and looking to store them in a local MongoDB.
If I have: class Post include MongoMapper::Document has_many :comments end If I do: class Comment include MongoMapper::EmbeddedDocument
I have an index like this in my database (for my table entries): {\"created_at\": -1, \"search_id\": 1, \"services\":1}
What is the best way to set up an index or configure a capped collections in a Rails project开发者_开发百科?
I would like to know how I can reproduce开发者_Python百科 the following query as map reduce or any juice function from MongoMapper or MongoID:
class Comment include MongoMapper::Document scope :by_rating, lambda { |minimum| where(:rating.gte => minimum) }
Lets say we have a simple model that stores two integers, the min and the max. We would like to force min <= max.
This is just for my weekend project/study, I am very new to Sinatra and MongoDB. I\'ve installed the gems for mongoDB, such as: mongo, mongo_mapper and mongoid.
I\'m looking to Eager Load Associated Documents using MongoMapper. Say I have an author with a :has_one condition to a Post, I should be able to load the author using a single query
