所以,我有一个名为“状态更新助手”的助手和一个名为“餐助手”。需要访问帮助变量
我需要从膳食助手内访问状态更新辅助变量...
我已经尝试使用“包括StatusUpdatesHelper”我吃饭助手里面,虽然这似乎并没有工作。
这里是我的客人助手文件:
module MealsHelper
def total_of(macro)
current_user.meal_foods.map(¯o).inject(:+)
end
def pct_fat_satisfied
#how much of a macro is needed?
# fat_needed = fat factor * current lbm
fat_factor = current_user.fat_factor
current_lbm = current_user.status_update.first.current_lbm
fat_needed = fat_factor * current_lbm
#how much is in the meal?
fat_provided = total_of(:fat)
#percent needed
pct_fulfilled = fat_provided.to_f/fat_needed.to_f
return BigDecimal(pct_fulfilled, 2)*100
end
def pct_carbs_satisfied(tdee, deficit_pct)
#how many carbs are needed?
cals_needed = tdee.to_f * (1 - deficit_pct.to_f)
carbs_needed = cals_needed * 4
#how many carbs are provided?
carbs_provided = total_of(:carbs)
#what is the pct satisfied?
pct_fulfilled = carbs_provided.to_f/carbs_needed.to_f
return tdee
end
def pct_protein_satisfied
#how much protien is needed?
protein_factor = current_user.protein_factor
current_lbm = current_user.status_update.first.current_lbm
protein_needed = protein_factor * current_lbm
#how much protien is provided?
protein_provided = total_of(:protien)
#pct of protien satisfied?
pct_fulfilled = protein_provided.to_f/protein_needed.to_f
return BigDecimal(pct_fulfilled, 2)*100
end
end
,这里是状态更新帮助文件:

从膳食中显示来看,当我索要pct_carbs_fulfilled,它返回“无穷”。
如果我把“100”int返回部分它将返回“100”。
状态更新助手很好地工作。
我知道这不是一个宁静的策略,所以关于如何使它更加安宁的任何建议将非常感激。
所以我的问题是,为什么我在做什么不工作,我怎样才能得到这些变量传递到膳食显示视图?
这里的饭菜的一部分展示图,其中的变量被渲染
<td> <%= pct_fat_satisfied %>% </td>
<td> <%= @tdee %>% </td>
<td> <%= pct_protein_satisfied %>% </td>
谢谢!
我该怎么做才能改善这个问题?从我这里得到21个观点,没有答案。 – 2013-05-13 01:53:25
您以错误的方式使用助手。我意识到这并不能帮助你。我最好的建议:尝试在模型的方法中解决更多的逻辑。使用助手只用于显示的东西。 假装帮助者不存在。 – wintermeyer 2013-05-13 09:09:52
Grr lol我有一种直觉,我必须将这些方法转化为模型。这将会破坏我的代码的一大部分。好吧。我最好比拖延更快地做到这一点。 – 2013-05-14 03:20:34
