我在应用程序中添加了这一段编码,现在它不允许任何人注册。我收到以下错误:1个错误分配多参数属性。错误页面的标题是“UsersController #create中的ActiveRecord :: MultiparameterAssignmentErrors”。我不知道如何解决,因为其他帖子不幸没有帮助。有人有解决方案吗?
new.html.erb:
<div class="field">
<%= f.label :birthday %>
<%= f.date_select :birthday, :start_year => 1995, :end_year => 1930 %>
</div>
users_controller:
def create
@user = User.new(params[:user])
if @user.save
UserMailer.registration_confirmation(@user).deliver
session[:user_id] = @user.id
redirect_to root_url, notice: "Thank you for signing up!"
else
render "new"
end
end

实际问题是数据库中的值是在VARCHAR上,而应该是DATE。现在它工作正常。
答案 1 :(得分:1)
首先确保生日的类型应为Date
。
在参数中,生日的值如下所示。
"birthday(1i)"=>"1995", "birthday(2i)"=>"3", "birthday(3i)"=>"22"
但字段ID 日期的类型。我认为,在更新生日字段之前,我们需要生成相应的日期对象,然后需要更新对象。
@user.birthday = Date.strptime("#{params['birthday(3i)']}/#{params['birthday(2i)']}/#{params['birthday(1i)']}", "%d/%m/%y")
现在保存对象,希望这次不会引发任何错误。
如果仍然有错误,请告诉我。
