submission_id实际上是emailinterest对象的成员。 submission_id假设包含提交对象的ID值。
def create
@emailinterest = Emailinterest.new(params[:emailinterest])
@submission = Submission.find(params[:submission_id])
respond_to do |format|
if @emailinterest.save
Notifier.emailinterest_notification(@emailinterest, @submission).deliver
format.html { redirect_to(@emailinterest, :notice => 'Email was successfully sent!') }
format.xml { render :xml => @emailinterest, :status => :created, :location => @emailinterest }
else
format.html { render :action => "new" }
format.xml { render :xml => @emailinterest.errors, :status => :unprocessable_entity }
end
end
end
我一直被困在这条线上
@submission = Submission.find(params[:submission_id])
出现此错误。
Couldn't find Submission without an ID
提交和Emailinterest都是对象。
Emailinterest需要一些有关要创建的Submission对象成员的信息。
submission_id实际上是Emailinterest对象的成员。 submission_id假设包含Submission对象的ID值。
现在我将submission_id作为字符串值。它必须是整数值吗?

答案 0 :(得分:2)
此错误:
无法找到没有ID的提交
可能是由
引起的@submission = Submission.find(nil)
和nil
是Hash在你要求它没有的密钥时会给出的(除非有人提供了不同的默认值,但是params
并且它包含的Hashes应该给你nil
)。因此,您:submission_id
内没有params[:emailinterest]
。根据您的评论,我猜你确实有params[:submission_id]
所以试试这个:
@submission = Submission.find(params[:submission_id])
如果这不起作用,请执行logger.debug params.inspect
并查看日志以查看:submission_id
的位置(如果有的话)。
答案 1 :(得分:1)
它可以是字符串或任何东西,只要它可以转换为整数。
您可以使用rails控制台验证这一点:
ruby-1.9.2-p0 > Product.find("1")
Product Load (0.2ms) SELECT "products".* FROM "products" WHERE "products"."id" = ? LIMIT 1 [["id", "1"]]
=> #<Product id: 1, collection_id: nil, name: "test", description: nil, price: 1000, picture_file_name: nil, picture_content_type: nil, picture_file_size: nil, picture_updated_at: nil, created_at: "2011-07-14 10:10:45", updated_at: "2011-07-14 10:10:45">
如果您想知道submission_id
中的内容,可以通过将其放在方法的开头来记录该值:
logger.debug params[:emailinterest][:submission_id]
