我似乎無法將項目添加到散列。如何將散列元素添加到另一個散列?
我有以下方法,有一個散列傳入和意圖是傳出一個新的哈希從原來的。我已經證實,關鍵是一個字符串,其他兩個元素是浮動。當我請求時,b_name,lat和lng都會打印到日誌中。
def construct_paint_hash(list)
full_list = Hash.new
num = 100
list.each do |thing|
puts num
b_name = thing["name"]
puts b_name
lng = thing["longitude"]
lat = thing["latitude"]
full_list["#{b_name}"]=[lng, lat]
# full_list[:dsfsd] = "dsfdsfds"
num +=100
end
return full_list
end
以下是錯誤我得到:
Completed 500 Internal Server Error in 377ms (ActiveRecord: 0.0ms)
TypeError (no implicit conversion of String into Integer):
app/controllers/welcome_controller.rb:42:in `[]'
app/controllers/welcome_controller.rb:42:in `block in construct_paint_hash'
app/controllers/welcome_controller.rb:39:in `each'
app/controllers/welcome_controller.rb:39:in `construct_paint_hash'
app/controllers/welcome_controller.rb:11:in `index'
到底什麼我做錯了嗎?
我可以看到代碼調用'construct_paint_hash(名單)'? –
'LAT = get_lat()' 'LNG = get_lng()' 'thing_search = HTTParty.get(construct_location_search(緯度,經度))[ 「數據」]' 'thing_location_hash = construct_paint_hash(thing_search)' 'puts construct_paint_hash(thing_location_hash)' – notthehoff
