我正在制作一个输入表单，其功能不太适合常规的form_for模板rails提供。我想我会编写自己的HTML来模仿form_for的html输出，但是嵌入了其他form_for元素。
对于我可以使用rails框架的字段。对于其他人，我创建了隐藏字段来存储Rails的内容，以及常规输入字段，其值使用JavaScript操作以放入隐藏字段。
这是一个这样的领域：
State:<br>
<input type="text" class = "state name_input administrative_area_level_1">
<div class="field">
<input type="hidden" name="address[state]" id="state">
</div>
当我将隐藏字段的值发送到控制台时，我得到了很好的回复：
state 37
这意味着州字段保存值37.完美。
除了当我试图制作我的模型时，参数是空的：
"state"=>"",
我确实有一个无法隐藏的字段：
Street:<br><input type="text" id="street" name="address[street]">
所以我将状态输入类型更改为数字，如果它没有被隐藏，那就是它的结果。为什么不能找到我的参数？

您可以显示更多详细信息。我不能理解你做的100％事情，因为你写的很简单。但我想你需要测试参数名称是地址[状态]，但它不仅仅是状态，因为如果只有状态当然是零。
如果你的html渲染相同，那么我建议你应该在控制器中放一个调试，以便在提交表单时看到params返回控制器。
例如：在控制器中添加行：
def main():
inputList = get_user_input()
average = get_scores(inputList)
weightedAvgs = get_weightedavg(average, inputList)
results = get_class_grade(weightedAvgs)
ans = "yes"
while(ans == "yes"):
def get_user_input():
inputList = [] # initializes a list
# Gets how many scores for each category the user would like to enter and adds value to a list
tests = int(input("How many tests scores would you like to enter? "))
inputList.append(tests)
assignments = int(input("How many assignment scores would you like to enter: "))
inputList.append(assignments)
quizzes = int(input("How many quiz scores would you like to enter? "))
inputList.append(quizzes)
labs = int(input("How many lab scores would you like to enter? "))
inputList.append(labs)
final = int(input("How many final scores would you like to enter? "))
inputList.append(final)
# Gets the weight of each category if there are any scores to enter and adds the value to a list
if tests > 0:
testWeight = float(input("Enter the weight of tests: "))
inputList.append(testWeight)
else:
testWeight = 0
if assignments > 0:
assignmentWeight = float(input("Enter the weight of assignments: "))
inputList.append(assignmentWeight)
else:
assignmentWeight = 0
if quizzes > 0:
quizWeight = float(input("Enter the weight of quizzes: "))
inputList.append(assignmentWeight)
else:
quizWeight = 0
if labs > 0:
labWeight = float(input("Enter the weight of labs: "))
inputList.append(labWeight)
else:
labWeight = 0
if final > 0:
finalWeight = float(input("Enter the weight of the final: "))
inputList.append(finalWeight)

finalWeight = 0

如果您的表单没有直接绑定到对象模型，则可能很难使用form_for帮助程序。在这些情况下，您应该使用form_tag helper。阅读有关form_tag helper here的更多信息。
请参阅此stackoverflow答案，了解form_for和form_tag帮助程序之间的区别。
希望这有帮助。
