Hi Guys,
I''m having a similar problem to someone earlier on the board, but the
solutions posted aren''t working for me, so I figured I
wouldn''t hijack
the thread and started a new one:
I have an application that allows users to post updates, when they go to
the homepage I want the users details and a list of their updates to
show, however I''m having trouble with the find parameters.
Currently the model states that:
user has_many: updates
update belongs_to:user
I think this is correct (and the right pluralisation)?
the controller for the index page looks like this:
def index
@user = User.find(params[:id])
@updates = Update.find(params[:id]).updates
end
as explained in a previous thread
(http://www.ruby-forum.com/topic/150785)
I''ve also tried the different permutations of
@updates = Update.find(:all, :conditions =>["user_id =
?",> params[:user_id]])

When visiting the page I get this messageL
undefined method `updates'' for #<Update:0xb7582750>
Have I missed something rediculously obvious? this seems like it should
be a fairly trivial thing to get working but I''m pretty new to the
whole
rails experience...
cheers,
lee

Thanks for the quick reply Fred!
the params [:id] is a users id yes, do you mean to change the controller
to this:
def index
@user = User.find(params[:id])
@updates = @user.updates
end
this gave me an error of:
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.date
with the lines:
Extracted source (around line #19):
16: <h2>Updates</h2><br/>
17: <% for column in Update.content_columns %>
18: <p>
19: <b><%= column.human_name %>:</b> <%=h
@update.send(column.name) %>
20: </p>
21: <% end %>
22:
(which is where it begins outputting update information)
could this point at an error somewhere else in my code (if its
important, the app is mostly standard scaffold code)

btw, I just realised I was calling it @updates in the controller and @update in the view, I fixed this and got a shiny new error: undefined method `date'' for Update:Class Extracted source (around line #19): 16: <h2>Updates</h2><br/> 17: <% for column in Update.content_columns %> 18: <p> 19: <b><%= column.human_name %>:</b> <%=h @updates.send(column.name) %> 20: </p> 21: <% end %> 22: date is a field name in the updates table. cheers, Lee -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

at the risk of this becoming a monologue.. I''ve fixed the problem 19: <b><%= column.human_name %>:</b> <%=h @updates.send(column.name) needed to be 19: <b><%= column.human_name %>:</b> <%=h update.send(column.name) cheers for the help explaining how to reference the tables Fred! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
