所以,我有一个叫做“状态更新助手”的助手和一个叫做“膳食助手”的助手。
我需要从 Meals Helper 中访问 Status Updates Helper 中的变量...
我尝试在 Meals Helper 中使用“include StatusUpdatesHelper”,尽管这似乎不起作用。
这是我的膳食助手文件:
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
这是状态更新帮助文件:

在餐点显示视图中,当我要求 pct_carbs_fulfilled 时,它返回“infinity”。
如果我将“100”放入他返回的部分,它将返回“100”。
状态更新助手工作得很好。
我知道这不是一个宁静的策略,所以任何关于如何让它更宁静的建议将不胜感激。
所以我的问题是,为什么我没有做的工作,我怎样才能将这些变量传递到餐显示视图中?
这是正在呈现变量的餐点显示视图的一部分
<td> <%= pct_fat_satisfied %>% </td>
<td> <%= @tdee %>% </td>
<td> <%= pct_protein_satisfied %>% </td>
谢谢!
