Hi,
I have a simple program that tries to do something really basic.
First, I have a company Model :
-------------------------------------
class Company < ActiveRecord::Base
has_one :billingAddress, :foreign_key=>"id",
:class_name=>"Address"
end
Then I have the address Model :
--------------------------------------
class Address< ActiveRecord::Base
belongs_to :company
end
I''ve created manually an entry in the DB for Address and Company and
I''ve linked them (Company table has a "billingAddress_id"
row)
In my views "company/_form"(scaffold generated), I want to display the
address form. So I added (following Rails Guides) the following line to
my view :
<%= render :partial => "addresses/edit", :locals => {
:shippingAddress
=> @address} %>
It keeps saying : "undefined method `model_name'' for
NilClass:Class "
tried this :
<%= render :partial => "addresses/edit", :locals => {
@company.shippingAddress => @address} %>
with the same result
I''ve tried with :
<%= render :partial => "addresses/form", :object =>
@billingAddress%>
and I got the same result (this is normal I think since I don''t have a
billingAddress object but a Company object.
Finally, I''ve tried :
<%= :partial => "addresses/form", :object =>
@company.shippingAddress %>
and the error I got was :
syntax error, unexpected tASSOC, expecting '')
When I load the Company with rails console, it loads perfectly. However
I cannot manage to call the aggregated object view since the name of the
variable is not the same name as the class name... at least, that what I
think it is :-)
Can someone help me to figure this out ? I thought that this will be a
simple task but it figures that it is not...
Thank you very much for your time !

I have no experience of Rails 3, which is still under development. You did not answer the question as to whether you are accessing something.model_name, nor whether the trace shows the failing line. You do not specify your knowledge level, if you are just starting I would not recommend rails 3. You will never know whether a problem is down to your experience or a problem with rails itself.

This means that foreign key to address is named ''id'' which is actually id column for Company model. Remove this part if your foreign key column is ''address_id'' or use real column name, i.e. ''billing_address_id'' otherwise Regards, Bosko -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

My knowledge level is ... well, begginer since I''m not able to make this thing works :-) My years of experience are with PHP and .Net. I''m trying Rails because it looks interesting and promising (once I''ll get a solid grip on basic things like this!) Here is my partial view for the Address class. 1<%= form_for(@address) do |f| %> 2 <div class="field"> 3 <%= f.label :city %><br /> 4 <%= f.text_field :city %> 5 </div> 6 7<% end %> The failling line is #3. I''m able to load the partial if I put in it a string and no code (like "<h1> TEST </h1>"). I''m not sure that I understand what you meant by "something.model_name" ... As for Rails 3, they said on guides.rails.info : "But if you’re starting development on a new application and you don’t mind getting wind in your hair, please do jump on board!" I''m starting a new app and I''m eager to learn so that''s what I''ve done.... is it a choice that bad ? Thank you for you replies !

I''m not sure that I > understand what you meant by "something.model_name"I think Bosko may well have the answer. I was assuming that one of your models had a file model_name but I see now that this is the rails model it is talking about. ...

You will not find many tutorials and guides for rails 3 yet. I would consider going back to 2.3.x and starting with the guides at http://guides.rubyonrails.org/ Colin> > Thank you for you replies ! > Greg > > > -- > Posted via http://www.ruby-forum.com/. > > -- > You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to rubyonrails-talk+unsubscribe@googlegroups.com. > For more options, visit this group at http://groups.google.com/group/rubyonrails-talk?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

@Bosko : I''ll try your suggestion tonight and keeps you posted. @Collin : Thanks for your time... I''ll check for rails 2.3.x and if I''m not able to make this work, I may roll back Thank you guys for your help ! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
