Search for array in jsonb field (address components from Google maps) - sql

Question

I have a table events with a location_details jsonb field, sometimes empty, sometimes filled with records like this:
{
"icon": "https://maps.gstatic.com/mapfiles/place_api/icons/v1/png_71/geocode-71.png",
"name": "Boulevard Pershing",
"geometry": {
"location": {
"lat": 48.8805276,
"lng": 2.283755
},
"viewport": {
"east": 2.285103980291502,
"west": 2.282406019708498,
"north": 48.8818765802915,
"south": 48.8791786197085
}
},
"html_attributions": [
],
"address_components": [
{
"types": [
"route"
],
"long_name": "Boulevard Pershing",
"short_name": "Boulevard Pershing"
},
{
"types": [
"locality",
"political"
],
"long_name": "Paris",
"short_name": "Paris"
},
{
"types": [
"administrative_area_level_2",
"political"
],
"long_name": "Département de Paris",
"short_name": "Département de Paris"
},
{
"types": [
"administrative_area_level_1",
"political"
],
"long_name": "Île-de-France",
"short_name": "IDF"
},
{
"types": [
"country",
"political"
],
"long_name": "France",
"short_name": "FR"
},
{
"types": [
"postal_code"
],
"long_name": "75017",
"short_name": "75017"
}
]
}
I would like to let users search events by location, but not by precise location (e.g. "route" in this example).
any idea on how I can do that?

Answer 1

I parsed the address_components so that they can be easily accessed in SQL:
{
"icon": "https://maps.gstatic.com/mapfiles/place_api/icons/v1/png_71/geocode-71.png",
"name": "Boulevard Pershing",
"geometry": {
"location": {
"lat": 48.8805276,
"lng": 2.283755
},
"viewport": {
"east": 2.285103980291502,
"west": 2.282406019708498,
"north": 48.8818765802915,
"south": 48.8791786197085
}
},
"html_attributions": [
],
"address_components": [
{
"types": [
"route"
],
"long_name": "Boulevard Pershing",
"short_name": "Boulevard Pershing"
},
{
"types": [
"locality",
"political"
],
"long_name": "Paris",
"short_name": "Paris"
},
{
"types": [
"administrative_area_level_2",
"political"
],
"long_name": "Département de Paris",
"short_name": "Département de Paris"
},
{
"types": [
"administrative_area_level_1",
"political"
],
"long_name": "Île-de-France",
"short_name": "IDF"
},
{
"types": [
"country",
"political"
],
"long_name": "France",
"short_name": "FR"
},
{
"types": [
"postal_code"
],
"long_name": "75017",
"short_name": "75017"
}
],
"address_components_parsed": {
"route": {
"short_name": "Boulevard Pershing",
"long_name": "Boulevard Pershing"
},
"locality": {
"short_name": "Paris",
"long_name": "Paris"
},
"political": {
"short_name": "FR",
"long_name": "France"
},
"administrative_area_level_2": {
"short_name": "Département de Paris",
"long_name": "Département de Paris"
},
"administrative_area_level_1": {
"short_name": "IDF",
"long_name": "Île-de-France"
},
"country": {
"short_name": "FR",
"long_name": "France"
},
"postal_code": {
"short_name": "75017",
"long_name": "75017"
}
}
}
revelant ruby code:
def location_details=(value)
return if value.blank?
value =
value.is_a?(String) ? JSON.parse(value.presence || "{}") : (value || {})
value["address_components_parsed"] =
address_components_for(value["address_components"])
super(value)
rescue JSON::ParserError
errors.add(:location_details, I18n.t("events.errors.is_not_valid_json"))
super(value)
end
def address_components
(location_details || {}).fetch("address_components_parsed", {})
end
def address_components_for(address_components)
(location_details || {})
.fetch("address_components", {})
.each_with_object({}) do |el, acc|
el["types"].each do |type|
acc[type] ||= {}
acc[type]["short_name"] = el["short_name"]
acc[type]["long_name"] = el["long_name"]
end
end
end
