问题描述
我想弄清楚我的想法是
I'm losing my mind trying to figure this out:
有一个注册模块可以避开主要的devise注册控制器，我必须手动实例化使用User.new（...）创建由Devise生成的用户模型。我正在使用form_tag提交User.new（）所需的所有必要参数。这是我的代码的简化版本：
There's a registration module which side-steps the main devise registrations controller, and I have to manually instantiate the Devise-generated user model using User.new(...). I'm using a form_tag to submit all of the necessary parameters necessary for User.new(). Here's a truncated version of my code:
def registration_three
@user = User.new(:email => params[:email], :password => params[:password], :password_confirmation => params[:password_confirmation])
@user.save
@user = User.new(:email => '[email protected]', :password => 'qwertyui', :password_confirmation => 'qwertyui')
@user.save
end
第二个@ user.save有效，但第一个无效。根据stdout中的print语句，params [：email]，params [：password]和params [：password_confirmation]当然存在。
The second @user.save works, but the first one doesn't. params[:email], params[:password], and params[:password_confirmation] certainly exist, according to the print statements in stdout.
有人有什么想法吗？
编辑：
因此，我尝试将第二个User.new（...）中的所有单引号字符串更改为双引号字符串，例如那些存储在params哈希中的代码...第二个实例化也失败了。因此，我相当确定这个问题涉及双引号和单引号字符串。有人知道如何将双引号字符串转换为单引号字符串吗？提前致谢。
So I tried changing all of the single-quote strings in the second User.new(...) to double-quote strings like the ones stored in the params hash...and the second instantiation failed as well. So I'm fairly sure that the issue involves double- vs single-quote strings. Anyone know how to convert double-quote strings to single-quote ones? Thanks in advance.
推荐答案
首先将参数存储在变量中，然后在查询中使用它们以避免引用错误
Store your params in variable first then use them in query to avoid quote errors
