Array attribute types incorrectly rendered with Jbuilder using key_format! option
When using gon with Jbuilder and the key_format! :camelize :lower option, array database attributes are incorrectly parsed to json. Visiting the .json route displays the correctly parsed JSON from Jbuilder, but the JSON from Gon inside the <head> tag on the page is incorrect.
Example:
Attribute is stored in a database array attribute:
schema.rb
create_table "conditions", id: :uuid, default: -> { "gen_random_uuid()" }, force: :cascade do |t|
t.string "determinant_name"
t.string "operator"
t.string "condition_value", default: [], array: true
end
Jbuilder template uses the key_format! option to convert snake_case to camelCase:
_form.json.jbuilder
json.key_format! camelize: :lower
json.rules @rules do |rule|
json.(rule, :id)
json.conditionsAttributes rule.conditions do |condition|
json.(condition, :determinant_name, :condition_value, :operator)
end
end
Expected result:
rules: [
{
id: "a915ba39-fa2e-4a47-ab04-20ecc330080e",
conditionsAttributes: [
{
determinantName: "States",
operator: "One of These",
conditionValue: ["Alaska","California"]
}
]
}
]
Actual result:
rules: [
{
id: "a915ba39-fa2e-4a47-ab04-20ecc330080e",
conditionsAttributes: [
{
determinantName: "States",
operator: "One of These",
conditionValue: ["0"]
}
]
}
]
