Hi,

I wonder how I can insert “OR” in has\_and\_belongs\_to\_many conditions?

Code:  
has\_and\_belongs\_to\_many :projects, :conditions =\>  
[“projects\_users.user\_id = 0”]

Console:  
user.projects

SQL:  
Project Load (0.3ms) … WHERE (“projects\_users”.user\_id = 1 AND  
(projects\_users.user\_id = 0))

I wonder if I can change AND to OR

Thanks for help 😃
