Expand on yesterday's project to support Birds and Users.
- Practice embedded relationships.
- Practice reference relationships.
We will:
- Add a User model.
- Add a Bird schema.
- Refactor our Sighting model to support User via reference, and Bird via an embedded document.
- Add a POST endpoint for User.
- Adjust our GET endpoint for the Sighting model.
To avoid data collisions, let's change the db name to birds-mongoose-2
.
Identify the type of relationships we will be creating.
[{
"user": "aUserID",
"birds": [{
"name": "red breasted merganser",
"order": "Anseriformes",
"status": "least concern"
},
{
"name": "cedar waxwing",
"order": "Passeriformes",
"status": "least concern"
}],
"confirmed": true,
"numberSeen": 2
},
{
"user": "aUserID",
"birds": [{
"name": "osprey",
"order": "Accipitriformes",
"status": "least concern"
}],
"confirmed": false,
"numberSeen": 1
}]
[{
"email": "doh@msn.com",
"username": "homersimpson2000",
"level": 98,
"location": "Springfield",
"member": true
},
{
"email": "da.swamp@crocs.com",
"username": "ridnick1",
"level": 2,
"location": "Louisiana",
"member": false
}]
In a new file, Bird.js
, create a Bird schema using properties from the existing Sighting model. Name, order, and status will be the properties moved to our Bird object.
In a new file, User.js
, create a User model with the schema properties email, username, level, location, and member.
Declare a var referencing your User model in server.js
.
Add a property to the Sighting schema called user
that will create a relationship between a User and and Sighting. Each Sighting should be required to be related to only one User. A user may have multiple sightings.
Add another property called bird
that will store embedded data related to a specific bird when a new sighting is created.
Add a POST endpoint for creating new users: /api/users
. Test it with real data.
- POST a new
/api/sighting
, this time using the new Sighting data and a User id. - When GET
/api/sighting
is requested make sure to populate it with User data before returning it to the client. - Make it possible for the client to request sightings for a specific user by through sending the user id as a part of the request query in addition to
status
.
