ruby-on-rails - 我收到错误 'Unknown key for a VALUE_STRING in [q]'

Question

搜索时，我将elasticsearch用于城市的下拉列表。

Error: Elasticsearch::Transport::Transport::Errors::BadRequest Unknown key for a VALUE_STRING in [q]

我检查了所有传递的参数，一切都应该正确

Answer 1

尽管如此，错误的参数还是传给我。

更正为:

位置 Controller :

def fetch_locations
    locations = []
    p params[:q]
    search = CountryCity.search(params[:q])

    search.each do |result|
      locations << result.city + ', ' + result.name
    end

    render json: {locations: locations}
end

城市模型:

def self.search params
    CountryCity.__elasticsearch__.search(params)
end
