Bit new at this so not sure if this is something that shouldn''t be done but I currently have a number of models which are attached to database tables and deal with all the backend actions like populating editing and updating of the tables. I now want to be able to create a user view to take care of the end user actions, searching etc , this is working fine and i have a model and controller sorted to do the searching, once i''ve found and displayed a list of the data though i want to be able to call the show view of the backend model is it possible to use a link_to or something else to make this call from one model to another when i try to do it at the moment the link to is just searching within the current view folder Any help on this would be great Cheers Matt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

- models don''t "deal with [...] like populating editing and updating of the tables." thats the controllers job. Controllers do actions with help of the model. - link_to dosn''t link to views, only to controllers and actions. - You don''t need different models for backend and frontend - you only (might) need different controllers. for those points i''m a bit confused about what your problem exactly is.

Hi Thorsten, Thanks for the reply, Its quite possible I have too many of everything! very new to this and more than a little confused! Basically I have a model covering a table holding degree programmes and a model covering a table holding careers information(habtm), at the moment they both have thier own controllers and views which are fairly similar to the original scaffold, is this wrong? what i''m trying to do now is put in place a single front end page for the user to access a search function for both tables, at the moment this also has its own model called main and controller because I couldn''t work out where to put its view otherwise? so where I am at is that once i have the search results for either careers or degrees I want to let the user click a link to go to the show view of the appropriate model, but I can''t work out how to do this from the results.rhtml page which is held in the view for main. Very convoluted I know, which does lead me to suspect i''m not doing it how its supposed to be done but any pointers or a solution would be grand cheers On Jul 27, 1:29 pm, Thorsten <duple...-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org> wrote:> - models don''t "deal with [...] like populating editing and updating > of the tables." thats the controllers job.

One model (approx) per table, because each table row is an instance of an object.> > I now want to be able to create a user view to take care of the end > user actions, searching etc , this is working fine and i have a model > and controller sorted to do the searching, once i''ve found andI don''t think you should need a model for the searching. Basically the actions provoked by the view invoke methods of the controller. I think it''s probably OK to have a model for the searching, if you prefer that, it''s just it isn''t strictly necessary to make that an object.> displayed a list of the data though i want to be able to call the show > view of the backend model is it possible to use a link_to or something > else to make this call from one model to another when i try to do it > at the moment the link to is just searching within the current view > folderI think you are a bit mixed up about the model, view, controller setup. This is about separation of concerns. The models are the data made into objects (reified, if you like) that the controllers manipulate. The controllers display this as views. Thus if the view changes, the controller is not concerned with presentation, so need not be changed at the same time. If the model changes, the view need not necessarily (the change may only affect business logic). There are times when all will be affected, but in general they won''t. I think the best description I''ve seen of this is in "Head First Design Patterns".

OK
you have 2 tables in db (3 including your join table, since its a
habtm relationship) their for you have 2 models 1 for each table.
next make sure that the relationships are correct in the models
class Career < ActiveRecord::Base
has_and_belongs_to_many :degrees
class Degree < ActiveRecord::Base
has_and_belongs_to_many :careers
Then in your controller call
@careers = Career.find(...)
in the appropriate view/method
because you have you table associations set up right you will be able
to call degrees results from from your careers variable
<% for career in @careers %>
<% for degree in career.degrees %>
<%= degree %>
<% end %>
<% end %>
I hope this helps but im not sure as I found your 1st and 2nd
description of the problem a little hard to follow.
Best advice i can give you is buy "agile web development with rails"
from pragmatic bookshelf

For anyone else trying to do this in the end the solution was to
specify a different controller in the link_to call
<%= link_to "Show",
{ :controller => "careers", :action =>
"show", :id => career
}%>
