Hii  
How can i pass array of values from the controller to partial.

def dispfriends  
@myfriend=[]  
@myfriendlogin = []  
@myusers=[]

i=0  
@currentgroup = Group.find\_by\_id(params[:groupid])

puts @currentgroup.id

@currentfriends=  
GroupFriend.find\_all\_by\_user\_id\_and\_group\_id(current\_user.id,  
@currentgroup.id)

for n in @currentfriends  
@myfriend=n.friend\_id  
puts @myfriend  
@myusers = User.find\_by\_id(@myfriend)  
@myfriendlogin[i]=@myusers.id  
puts @myfriendlogin[i]  
i=i+1

end

I can print @myfriendlogin (id, name, address) individually and show the  
value in the view. But,

My requirement is I need to pass complete @myusers array to my view.

Please help like how can i pass all the fields in @myusers.

Please help. thank you.

Just like you’d pass any other variable to any other view. No  
difference.

This is terrible controller code. To start with, the name of the method  
is bad.

No! Use associations for this.

That’s not how you do it in Ruby. Learn about Array methods such as  
each and collect.

It’s just a variable. Pass it like any other variable.
