当我致电ContactUser.new时,我收到以下错误:
contact_user.rb:13: syntax error, unexpected ')', expecting '='
contact_user.rb:19: syntax error, unexpected kEND, expecting $end
通常这样的错误很明显,但我似乎无法确定原因。任何帮助将不胜感激。
class ContactUser < ActiveRecord::Base
include Tableless
column :name, :string
column :email, :string
column :category, :string
column :message, :text
column :recipient, :string
validates_presence_of :name, :email, :category, :message, :recipient
def self.create_from_params(params={}, recipient)
params[:message].encode!('US-ASCII', :undef => :replace) # re-encode message in US ASCII to ensure mailer works with it
ContactUser.create(:name => params[:name], :email => params[:email], :category => params[:category], :message => params[:message], :recipient => recipient)
end
end
module Tableless
def self.included(base)
base.extend(ClassMethods)
end
module ClassMethods
def columns() @columns ||= []; end
def column(name, sql_type=nil, default=nil, null=true)
columns << ActiveRecord::ConnectionAdapters::Column.new(name.to_s, default, sql_type.to_s, null)
end
end
def save(validate=true)
validate ? valid? : true
end
end
答案 0 :(得分:4)
这是你的问题:
def self.create_from_params(params={}, recipient)
#---------------------------------^^^
您要将params
参数的默认值声明为create_from_params
,但您没有为recipient
提供默认值。默认值的参数必须出现在参数列表的末尾,并且没有默认值的参数不能跟随它们。
此错误消息:
contact_user.rb:13: syntax error, unexpected ')', expecting '='
告诉我们Ruby在命中参数列表的右括号时期望看到recipient
默认值的等号。
