Passing values from controller to partial

Rails
1

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][email protected]
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.

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

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

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)

No! Use associations for this.

for n in @currentfriends
@myfriend=n.friend_id
puts @myfriend
@myusers = User.find_by_id(@myfriend)
@myfriendlogin[i][email protected]
puts @myfriendlogin[i]
i=i+1

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

end

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

Please help. thank you.
