FlexRest处理字符串数组

rest ruby ruby-on-rails

moondaisy · 技术社区 · 8 年前

我使用FlexRest向一个端点发出请求,该端点返回一个字符串数组 Content-Type: application\json .

这就是模型:

class Neighborhood < BaseModel
  get :by_location, "/neighborhoods/by_location"
end

我就是这样提出请求的:

def get_neighborhood_list
  city_to_use = ApplicationHelper.user_location[:city] || Rails.configuration.default_location[:city]
  @hoods = Neighborhood.by_location(city: city_to_use)
end

这被称为,但它只到达 super 因为它在里面断裂了:

def handle_response(response, cached = nil)
  result = super(response, cached)
  setup_paging_variables result, response
  setup_paging_variables result.data, response if result.respond_to? 'data'
  result
end

端点返回一个字符串数组:

[
    "Ahwatukee Foothills Village",
    "Alhambra",
    "Camelback East Village",
    "Central City",
]

用这个标题

我的问题是,FlexRest将字符串视为json对象,这是因为 Content-Type 头球。我得到了这个错误

TypeError:没有将符号隐式转换为整数

在这条线上 if attributes[:_links] . 它到达那里是因为 hal_response? 这是真的

为了让FlexRest停止这样的行为,我需要特别做些什么吗?

使现代化

我想我没解释清楚。错误发生在gem端。以下是全部错误:

TypeError - no implicit conversion of Symbol into Integer:
  flexirest (1.5.5) lib/flexirest/request.rb:612:in `handle_hal_links_embedded'

  flexirest (1.5.5) lib/flexirest/mapping.rb:28:in `block in _map_call'
  app/controllers/application_controller.rb:93:in `get_neighborhood_list

这个 如果属性[:_链接] 行是gem代码的一部分,它是 here on this line

当它到达这一行时 attributes 是响应中的字符串之一,例如: attributes = "Ahwatukee Foothills Village" .这就是它给出错误的原因。

我想弄清楚的是,是否有一种方法(可能是配置中的某种东西)可以使用FlexRest来处理此类响应。

这是个老问题,但我想我会回答的。你需要补充

朴素:没错

在你的模型中,如下所示。

class Neighborhood < BaseModel
  get :by_location, "/neighborhoods/by_location", plain: true
end

然后它将返回字符串数组
