我似乎无法将项目添加到散列。如何将散列元素添加到另一个散列?
我有以下方法,有一个散列传入和意图是传出一个新的哈希从原来的。我已经证实,关键是一个字符串,其他两个元素是浮动。当我请求时,b_name,lat和lng都会打印到日志中。
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
以下是错误我得到:
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'
到底什么我做错了吗?
我可以看到代码调用'construct_paint_hash(名单)'? –
'LAT = get_lat()' 'LNG = get_lng()' 'thing_search = HTTParty.get(construct_location_search(纬度,经度))[ “数据”]' 'thing_location_hash = construct_paint_hash(thing_search)' 'puts construct_paint_hash(thing_location_hash)' – notthehoff
