I have the following structure: <pre><code>class User include Mongoid::Document end class Resource include Mongoid::Document embeds_many :permissions end class Permission include Mongoid::Document embedded_in :resource field :read, type: Boolean field :write, type: Boolean field :user_id, type: BSON::ObjectId end </code></pre> Now let's suppose I have the following data: <pre><code>1.9.3p194 :001 > a = User.create => #<User _id: 4ff46818f83222daf9000001, _type: nil> 1.9.3p194 :002 > b = User.create => #<User _id: 4ff4681bf83222daf9000002, _type: nil> 1.9.3p194 :003 > r = Resource.create => #<Resource _id: 4ff46822f83222daf9000003, _type: nil> 1.9.3p194 :004 > r.permissions.create(read: true, user_id: a.id) => #<Permission _id: 4ff46835f83222daf9000004, _type: nil, read: true, write: nil, user_id: 4ff46818f83222daf9000001> 1.9.3p194 :005 > r.permissions.create(read: true, write: true, user_id: b.id) => #<Permission _id: 4ff4684af83222daf9000005, _type: nil, read: true, write: true, user_id: 4ff4681bf83222daf9000002> </code></pre> Now I want to find all Resources for which User A has write access (which should be none) <pre><code>1.9.3p194 :007 > Resource.where('permissions.write' => true).where('permissions.user_id' => a.id).all.entries => [#<Resource _id: 4ff46822f83222daf9000003, _type: nil>] </code></pre> This obviously fails because for each <code>where</code> clause there is a match. What would be the correct solution for this? Is there a way to do an <code>and</code> for embedded document queries?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
