2 用一个变量查找条件
现在我的 Projects.paginate 中只有一个条件 代码如下，
def list
@projects = Project.paginate(:page => params[:page], :per_page => 100, :order => (sort_column + ' ' + arrow), :conditions => ["description LIKE ?", "%#{query}%"])
我想在这里添加另一个条件，但事实证明它很困难。我尝试过
@projects = Project.paginate(:page => params[:page], :per_page => 100, :order => (sort_column + ' ' + arrow), :conditions => ["description OR name LIKE ?", "%#{query}%"])
，但我从 SQL 控制器收到绑定错误。有什么想法吗？我也不能使用 = 符号。
Right now I have only one condition in my Projects.paginate
Code is below
def list
@projects = Project.paginate(:page => params[:page], :per_page => 100, :order => (sort_column + ' ' + arrow), :conditions => ["description LIKE ?", "%#{query}%"])
I want to put another condition here but its is proving to be difficult. I'v tried
@projects = Project.paginate(:page => params[:page], :per_page => 100, :order => (sort_column + ' ' + arrow), :conditions => ["description OR name LIKE ?", "%#{query}%"])
but im getting a bind error from the SQL controller. Any ideas? I cant use the = sign either.

您的条件数组中需要有两个绑定变量：
