How to handle Profile Informations with :has_many_through ?

Hi,

i try to implement a Profile System for the users into my Rails App. i want to implement it with these models:

class Profile < ActiveRecord::Base   has_many :Profileships   has_many :users, :through => :Profileships   # Gehört zu einer Profil Gruppe   belongs_to :profile_group end

class Profileship < ActiveRecord::Base     belongs_to :user     belongs_to :Profile end

class ProfileGroup < ActiveRecord::Base   # Eine Profil Gruppe hat mehrere Profile   has_many :profiles end

So a user can edit his Profile informations of a Profile group, stored in the Profileship Database(there is a value fieldin the Profileship table). Do you think this is a good solution, or should i manage the Profile informations in one model and avoid the :has_many_through thing? How should i handle the views, because i think i have to setup a view for every Profilegroup, because i cant build them dynamical, because i can't figure out if a information needs a input or a textare or .... .

What you have setup there is a Many to Many association. Is that really what you want? Can one profile belong to multiple users?

If you give us a better understanding of your end goal we may be able to help more.

Thats right, because every User has the same profile fields , the possible Profile fields are saved in the Profile model. The value of a profile field of one user is saved in the Profileship model in the field "value". So how can i put that in a view based on the Profilegroup?

What on earth are you trying to achieve? What is a profile group for?

How do you want this to work from the user's perspective?

So, for example there are profile field for work, main profile fields, contact field (msn, email, adress....) and so. So i think there is usage for the user.

These could all be in the User model or, failing that, in a separate Profile model where User has_one :profile. Why do you need Profileship and ProfileGroup?

So i think there is usage for the user.

Not as far as you've explained. Please explain more clearly if I've missed something.

Let me explain Why i Write the Models: i'm Coming from Database Development, so normalization is very Important for me. If i create just a Profile Model and put all possible profile Fields into that, than there is no normalization Should i avoid the normalization in Case of RoR and keep the Models assimple As possible?

To me too.

Of course there is. Won't every user have the same set of profile fields?

If not, what is your use case? No theory for the moment, just an actual example.

No, you should normalize without overcomplicating.
