Global ID - Reference models by URI

A Global ID is an app wide URI that uniquely identifies a model instance:

gid://YourApp/Some::Model/id

This is helpful when you need a single identifier to reference different classes of objects.

One example is job scheduling. We need to reference a model object rather than serialize the object itself. We can pass a Global ID that can be used to locate the model when it's time to perform the job. The job scheduler doesn't need to know the details of model naming and IDs, just that it has a global identifier that references a model.

Another example is a drop-down list of options, consisting of both Users and Groups. Normally we'd need to come up with our own ad hoc scheme to reference them. With Global IDs, we have a universal identifier that works for objects of both classes.

Usage

Mix GlobalID::Identification into any model with a #find(id) class method. Support is automatically included in Active Record.

>> person_gid=Person.find(1).to_global_id=>#<GlobalID ...
>> person_gid.uri=>#<URI ...
>> person_gid.to_s=>"gid://app/Person/1"
>> GlobalID::Locator.locateperson_gid=>#<Person:0x007fae94bf6298 @id="1">

Signed Global IDs

For added security GlobalIDs can also be signed to ensure that the data hasn't been tampered with.

>> person_gid=Person.find(1).to_signed_global_id=>#<SignedGlobalID:0x007fea1944b410
>> person_sgid=Person.find(1).to_sgid=>#<SignedGlobalID:0x007fea1944b410
>> person_sgid.to_s=>"BAhJIh5naWQ6Ly9pZGluYWlkaS9Vc2VyLzM5NTk5BjoGRVQ=--81d7358dd5ee2ca33189bb404592df5e8d11420e"
>> GlobalID::Locator.locate_signedperson_sgid=>#<Person:0x007fae94bf6298 @id="1">

You can even bump the security up some more by explaining what purpose a Signed Global ID is for. In this way evildoers can't reuse a sign-up form's SGID on the login page. For example.

>> signup_person_sgid=Person.find(1).to_sgid(for: 'signup_form')=>#<SignedGlobalID:0x007fea1984b520
>> GlobalID::Locator.locate_signed(signup_person_sgid,for: 'signup_form')=>#<Person:0x007fae94bf6298 @id="1">

You can also have SGIDs that expire some time in the future. This is useful if there's a resource, people shouldn't have indefinite access to, like a share link.

>> expiring_sgid=Document.find(5).to_sgid(expires_in: 2.hours,for: 'sharing')=>#<SignedGlobalID:0x008fde45df8937# Within 2 hours...
>> GlobalID::Locator.locate_signed(expiring_sgid,for: 'sharing')=>#<Document:0x007fae94bf6298 @id="5"># More than 2 hours later...
>> GlobalID::Locator.locate_signed(expiring_sgid,for: 'sharing')=>nil
>> explicit_expiring_sgid=SecretAgentMessage.find(5).to_sgid(expires_at: Time.now.advance(hours: 1))=>#<SignedGlobalID:0x008fde45df8937# 1 hour later...
>> GlobalID::Locator.locate_signedexplicit_expiring_sgid=>nil

Custom App Locator

A custom locator can be set for an app by calling GlobalID::Locator.use and providing an app locator to use for that app. A custom app locator is useful when different apps collaborate and reference each others' Global IDs. When finding a Global ID's model, the locator to use is based on the app name provided in the Global ID url.

A custom locator can either be a block or a class.

Using a block:

GlobalID::Locator.use:foodo |gid|
FooRemote.const_get(gid.model_name).find(gid.model_id)end

Using a class:

GlobalID::Locator.use:bar,BarLocator.newclassBarLocatordeflocate(gid)@search_client.searchname: gid.model_name,id: gid.model_idendend

After defining locators as above, URIs like "gid://foo/Person/1" and "gid://bar/Person/1" will now use the foo block locator and BarLocator respectively. Other apps will still keep using the default locator.

You can also have SGIDs that expire some time in the future. This is useful if there's a resource,
people shouldn't have indefinite access to, like a share link.

Custom App Locator
A custom locator can be set for an app by calling GlobalID::Locator.use and providing an app locator to use for that app.
A custom app locator is useful when different apps collaborate and reference each others' Global IDs.
When finding a Global ID's model, the locator to use is based on the app name provided in the Global ID url.
A custom locator can either be a block or a class.
Using a block:
GlobalID::Locator.use:foodo |gid|
FooRemote.const_get(gid.model_name).find(gid.model_id)end
Using a class:
GlobalID::Locator.use:bar,BarLocator.newclassBarLocatordeflocate(gid)@search_client.searchname: gid.model_name,id: gid.model_idendend
After defining locators as above, URIs like "gid://foo/Person/1" and "gid://bar/Person/1" will now use the foo block locator and BarLocator respectively.
Other apps will still keep using the default locator.

Global ID - Reference models by URI
A Global ID is an app wide URI that uniquely identifies a model instance:
gid://YourApp/Some::Model/id
This is helpful when you need a single identifier to reference different
classes of objects.
One example is job scheduling. We need to reference a model object rather than
serialize the object itself. We can pass a Global ID that can be used to locate
the model when it's time to perform the job. The job scheduler doesn't need to know
the details of model naming and IDs, just that it has a global identifier that
references a model.
Another example is a drop-down list of options, consisting of both Users and Groups.
Normally we'd need to come up with our own ad hoc scheme to reference them. With Global
IDs, we have a universal identifier that works for objects of both classes.
Usage
Mix GlobalID::Identification into any model with a #find(id) class method.
Support is automatically included in Active Record.
>> person_gid=Person.find(1).to_global_id=>#<GlobalID ...
>> person_gid.uri=>#<URI ...
>> person_gid.to_s=>"gid://app/Person/1"
>> GlobalID::Locator.locateperson_gid=>#<Person:0x007fae94bf6298 @id="1">
Signed Global IDs
For added security GlobalIDs can also be signed to ensure that the data hasn't been tampered with.
>> person_gid=Person.find(1).to_signed_global_id=>#<SignedGlobalID:0x007fea1944b410
>> person_sgid=Person.find(1).to_sgid=>#<SignedGlobalID:0x007fea1944b410

>> GlobalID::Locator.locate_signedperson_sgid=>#<Person:0x007fae94bf6298 @id="1">
You can even bump the security up some more by explaining what purpose a Signed Global ID is for.
In this way evildoers can't reuse a sign-up form's SGID on the login page. For example.
>> signup_person_sgid=Person.find(1).to_sgid(for: 'signup_form')=>#<SignedGlobalID:0x007fea1984b520
>> GlobalID::Locator.locate_signed(signup_person_sgid,for: 'signup_form')=>#<Person:0x007fae94bf6298 @id="1">
You can also have SGIDs that expire some time in the future. This is useful if there's a resource,
people shouldn't have indefinite access to, like a share link.
>> expiring_sgid=Document.find(5).to_sgid(expires_in: 2.hours,for: 'sharing')=>#<SignedGlobalID:0x008fde45df8937# Within 2 hours...
