Hi @jeromedoyle,
If you want to use Ecto rather than Poison’s protocols, here is an example.
I’m just casting the API response but you could also add Changeset validations if you want and only returning if valid? == true. Hope this helps!
defmodule MyApp.SmartyUSStreet.Response do
use Ecto.Schema
alias MyApp.Addresses.Address
import Ecto.Changeset
@primary_key false
embedded_schema do
field :input_id
field :input_index, :integer
field :candidate_index, :integer
field :addressee
field :delivery_line_1
field :delivery_line_2
field :last_line
field :delivery_point_barcode
embeds_one :components, Components do
field :street_name
field :city_name
field :default_city_name
field :state_abbreviation
field :zipcode
field :plus4_code
# ...
end
embeds_one :metadata, Metadata do
field :record_type
field :zip_type
field :county_fips
field :county_name
# ...
end
embeds_one :analysis, Analysis do
field :dpv_match_code
field :dpv_footnotes
field :dpv_cmra
# ...
end
end
def list_from_json(data) when is_binary(data) do
Poison.decode!(data) |> list_from_json()
end
def list_from_json(data) when is_list(data) do
data
|> Enum.map(fn x -> list_from_json(x) end)
|> List.flatten()
end
def list_from_json(data) when is_map(data) do
%__MODULE__{}
|> cast(data, castable_fields(__MODULE__))
|> cast_embed(:components, with: &embedded_changeset/2)
|> cast_embed(:metadata, with: &embedded_changeset/2)
|> cast_embed(:analysis, with: &embedded_changeset/2)
|> apply_changes()
|> List.wrap()
end
def castable_fields(schema_module) do
schema_module.__schema__(:fields) -- (schema_module.__schema__(:embeds) ++ schema_module.__schema__(:associations))
end
def embedded_changeset(struct, data) do
struct |> Ecto.Changeset.cast(data, castable_fields(struct.__struct__))
end
end
