推荐答案

如果您尝试在您的 params 模型，你违反了MVC的原则。模型应该独立于争论。如果您尝试执行以下操作：

If you're trying to use the params hash in your model, you are violating principles of MVC. The model should stand alone with arguments. If you are trying to do the following:

# controller
Model.foo

# model
def foo
  params[:bar].reverse!
end

您应该做以下事情：

# controller
Model.foo(params[:bar])

# model
def foo(foobar)
  foobar.reverse!
end
