Ruby on rails 如何使用我拥有的数据库表从rabl gem和money gem生成json响应?
这是我想从rablgem构建的jsonRuby on rails 如何使用我拥有的数据库表从rabl gem和money gem生成json响应?,ruby-on-rails,ruby,json,currency,rabl,Ruby On Rails,Ruby,Json,Currency,Rabl,这是我想从rablgem构建的json [ "M-0": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"}, "M-1": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"}, "M-2": {"revenue":"v
[
"M-0": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"},
"M-1": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"},
"M-2": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"},

"M-5": {"revenue":"value", "fee":"value", "created":"count", "paid":"count", "partially_paid":"count"}
]
这是我的数据库表
create_table "merchant_monthly_stats", force: true do |t|
t.integer "created_count", default: 0
t.integer "ready_count", default: 0
t.integer "paid_count", default: 0
t.integer "partially_paid_count", default: 0
t.integer "cancelled_count", default: 0
t.integer "failed_count", default: 0
t.integer "processed_count", default: 0
t.integer "expired_count", default: 0
t.integer "merchant_id", null: false
t.integer "year", null: false
t.integer "month", null: false
t.datetime "created_at"
t.datetime "updated_at"
t.integer "overdue_count", default: 0
t.integer "fee_centimes", default: 0, null: false
t.string "fee_currency", default: "XAF", null: false
t.integer "revenue_centimes", default: 0, null: false
t.string "revenue_currency", default: "XAF", null: false
end
这是我的控制器方法
def history
current_month = Time.now.month
current_year = Time.now.year
list_of_last_six_months = [current_month]
5.times do |i|
list_of_last_six_months << (current_month - i )
end
month_array =[]
list_of_last_six_months.each { |month|
record = MerchantMonthlyStat.find_by merchant_id: current_api_user.id, year: current_year, month: month
m = {
:revenue => Money.new(record.revenue_centimes , record.revenue_currency).format,
:fees => Money.new(record.fee_centimes,record.fee_currency).format,
:created => record.created_count ,
:paid => record.paid_count ,
:partially_paid => record.partially_paid_count }
month_array.push(m)
}
respond_with(month_array, status: :ok, template: 'api/merchant/mobiles/history')
end
Rabl文档为此编写了以下Rabl(这对我来说毫无意义):
但是我不知道如何应用它以rabl和我想要的格式获取我的month_数组?有人想解决这个问题吗?我被卡住了 只需使用
render:json
render json: month_array
无需修改模板,您已经在controller中构建了阵列
从评论更新:使month_数组实例变为VARABLE–将my_数组更改为@my_数组。然后在您的rabl模板中,只需编写collection@my_array,object_root:false,但您提供的看起来不像JSON。这些
M-0
,M-1
等标签是什么?我看不出有什么效果。你们的问题是为我写代码。那个么你们认为上面剩下的东西是谁写的呢?他们不是努力吗?我只是不太了解rails。我从一个星期开始学习,这就是我所能取得的进步。就这些。@EugZol我已经在中更正了jsonquestion@samo有大量的文档、精彩的维基页面和许多web示例。如果你尝试的话,这是可以做到的。事实上,我已经向我的前辈提出了这个建议,因为我很容易做到。但他说我们正在使用rabl,我需要学习它。否则我会把你标记为答案(好吧,你可以让month_array实例变为VARABLE–将my_array
更改为@my_array
。然后在你的rabl模板中只需编写collection@my_array,object_root:false
。欢迎你。如果你的上级要求你重构代码,将更多的东西从你的控制器移动到rabl,请随意询问其他问题。)我们也会想出一些办法:)如果你喜欢的话,考虑一下我的回答。但是我已经把它标记为答案。因为那是最有帮助的。你能更新你的答案吗?谢谢Eugzol。这也帮助我学习了rabl语法,以防有人想更好地理解
