hi, i'm working on an idea of mine using ruby on rails but totally stumped
with the has_many :notes, belongs_to :users in ruby
could someone explain this to me?
basically every user will be able to create many notes (notes being a record
with a body text field), but those individual notes will only relate to the
user who created them.
so joe won't be able to see sally's note records
how do i do this?
can anyone point me to an easy example, done the authentication and
everything else, just can't get my head around this one.
Hi!
By what i can understand is “Creator alone see his/her own notes”. For this you need to store creator_id or user_id in the notes table ans wherever you are displaying the notes just check if the note if from the user who has logged in.
So, say session[:id] is having the id of the user who has logged in and in the rhtml somewhere you are having, @notes as collection of notes then while displaying you can write
<%for note in @notes
<%if note.user_id == session[:id]%>
Show notes data here
<%end%>
<%end%>
Hope this helps,
if you just want to display the notes specific to the currently logged
in user, you'd just use something like this (assuming current_user
returns the currently logged in user):
in your model:
user.rb
class User < ActiveRecord::Base
# each user will have many notes, each note will be associated with
# a user through a user_id column in the notes table
has_many :notes
end
note.rb
class Note < ActiveRecord::Base
# a note belongs to a single
belongs_to :user
end
in your controller:
def notes
#retrieve all the notes for the currently logged in user
@notes = current_user.notes
end
and in your view:
<% for note in @notes %>
<%= note.title %>
<%= note.body %>
....
<% end %>
