我正在创建一个习惯跟踪应用。
当用户养成习惯时,他会将:date_started
放入其中:committed
以及:committed
做习惯。
然后从习惯:date_started
开始:level
天的X :committed
天后移动到后续:level
(每个级别的天数在模型中细分>下面)。
换句话说,我们如何使用:level
天而不是任何一天来计算习惯:date_started
是什么?
据我所知,我当前的代码应该有效,但由于某些原因,无论用户为:committed
或class CreateHabits < ActiveRecord::Migration
def change
create_table :habits do |t|
t.integer :missed
t.datetime :left
t.integer :level
t.text :committed
t.datetime :date_started
t.string :trigger
t.string :action
t.string :target
t.string :positive
t.string :negative
t.references :user, index: true
t.timestamps null: false
end
add_foreign_key :habits, :users
add_index :habits, [:user_id, :created_at]
end
end
添加什么,class Habit < ActiveRecord::Base
belongs_to :user
before_save :set_level
validates :action, presence: true
serialize :committed, Array
scope :missed, -> { where(missed: 1) }
scope :nonmissed, -> { where(missed: 0) }
def levels
committed_wdays = committed.map { |day| Date::DAYNAMES.index(day) }
n_days = (date_started..Date.today).count { |date| committed_wdays.include? date.wday }
case n_days
when 0..9
1
when 10..24
2
when 25..44
3
when 45..69
4
when 70..99
5
else
"Mastery"
end
end
private
def set_level
self.level = levels
end
end
都不会改变。

我认为您唯一的问题是,您在committed
字段中以小写形式存储了日期名称,然后尝试将它们与Date::DAYNAMES
匹配,而committed_wdays = committed.map { |day| Date::DAYNAMES.index(day.titleize) }
n_days = ((date_started.to_date)..Date.today).count { |date| committed_wdays.include? date.wday }
在标题中包含它们。否则,逻辑看似合理。
这应该有效:

根据您的业务逻辑,有很多方法可以做到这一点。例如,如果您要解锁每个级别的某些权限,那么您希望以不同于级别仅显示UI功能的方式处理它。无论哪种方式,您都可以在:name属性中添加一个级别表,该级别表将保存您的级别名称。然后你会有一个habit_level表,它将与习惯的外键和级别的外键联接。当您更新日期时,您会检查天数是否为某个数字,如果是,则在连接表中创建相应级别和习惯的记录。

究竟是什么committed
?我明白了:
t.text :committed
和
committed.map { |day| Date::DAYNAMES.index(day) }
这不是很有意义,我不确定这对你有什么用。看起来您正在存储多天名称,如果是这种情况,您应该使用某种类型的数组(字符串或整数)。然后,您可以将n_days
设置为committed.length
。
我会将该列更改为t.string :committed, array: true, default: []
或t.integer :committed, array: true, default: []
。
