如何创建另一个控制器操作来在 Rails 中创建对象？
我有一个名为 Contact_Email 的模型。当电子邮件模板通过 ActionMailer 发送到特定联系人时，作为创建操作的一部分，它会在 .save 时发送该模板。
但是，我想创建一个“跳过”操作，它也会创建 Contact_Email，但不发送 ActionMailer 并允许我以不同的方式设置状态。
我想创建一个单独的操作，因为我想让它响应一个remote_for_tag，这样我就可以有一个ajax按钮指示它已被“跳过”：
这是我尝试过的，但是当它创建一个Contact_Email时，我最终得到当我想返回并再次查看所有联系人时出现错误。
def skip
@contact_email = ContactEmail.new
@contact_email.contact_id = params[:contact_id]
@contact_email.email_id = params[:email_id]
@contact_email.status = "skipped"
if @contact_email.save
flash[:notice] = "skipped email"
redirect_to contact_emails_url
end
end
I have a model called Contact_Email. When an Email template is sent through ActionMailer to a specific Contact, as part of the Create action it sends it through upon .save.
However, I want to create a "skip" action which also creates a Contact_Email, but does NOT send an ActionMailer and allows me to set the status differently.
I want to create a separate action because I want to make this respond to a remote_for_tag so that I can just have an ajax button indicate it has been "skipped":
Here's what I tried, but while it creates a Contact_Email, I end up getting an error when I want to go back and view all the Contacts again.
def skip
@contact_email = ContactEmail.new
@contact_email.contact_id = params[:contact_id]
@contact_email.email_id = params[:email_id]
@contact_email.status = "skipped"
if @contact_email.save
flash[:notice] = "skipped email"
redirect_to contact_emails_url
end
end

嗯，你的代码看起来没问题，只是有一些事情。
你没有 else 语句，如果你的
@contact_email 没有保存？
您绝对不应该单独分配所有参数。在 contact_email 视图中使用表单并
控制器中的
@contact_email = ContactEmail.new(params[:contact_email])。尽管单独“跳过”分配是可以的，但
map.resources :contact_emails, :member => {：跳过=> ：帖子}一切都应该很好
Well, your code seems ok, just a few things.
You have no else statement, what if your
@contact_email is not saved?
You should definately NOT assign all of the params separately. Use a form in the view for contact_email and
@contact_email = ContactEmail.new(params[:contact_email])in controller. Though having "skipped" assigned separately is okmap.resources :contact_emails, :member => {:skip => :post}And everything should be just fine
