Nearest local group

[pedro-gutierrez]

Is your feature request related to a problem? Please describe.

If a user doesn't know the exact name of a group, it is not easy to find it.

As a user/prospective volunteer,
I want to be able to find the closest group to my location
So that I can contact them and begin volunteering

Describe the solution you'd like

• A GraphQL query that returns a list of Groups, given a starting set of coordinates.
• We will need to extend the existing Address type, eg:

type Address {
...
  location: Coordinates!
...
}

• The addresses database table will also need a migration, so that we can store coordinates (latitude and longitude) for each address. Existing queries and mutations and tests might also need to be reviewed, unless we decide to make this optional.

GraphQL contract:

type Coordinates {
  latitude: Float!
  longitude: Float!
}

type Query {
  findGroupsNearby(to: Coordinates!, limit: Int!): [Group!]!
}

• The GraphQL resolver should be thin and delegate to a Ferry.Locations.findGroupsNearby context function.
• Given that the database model allows for a single group to have multiple addresses, we need to account for potential duplicates in the returned list.
• We will need to rely on Postgres' geospatial extensions in order to implement this feature.

👋 I'm pondering trying this out, but no promises. One question:

Users must enter their country and postal code to search

Any objection to offering browser Geolocation as an option in addition?

Hello! thank you for getting in touch! It would be awesome to have this feature indeed. This ticket is a bit old, so I just reworked the description, please let me know if the new spec is more in line with what you were suggesting? Happy to assist if you need any help or further clarification.
