Hi there,
I ran into an error I don''t fully understand, and some cursory Googling
didn''t yield any answers (at least none that I understood).
I''m creating
a page where users have to verify something by submitting a form. Doing
so inserts a value into their user record. Here''s what I have:
controller:
def profile_link
@current_fb = session[:fbsession].session_uid
@user = User.find(params[:id])
end
profile_link.rhtml:
<%= start_form_tag :controller => ''users'', :action =>
''update'', :id =>
@user %>
<%= hidden_field "user", "facebook_id", @current_fb
%>
<%= submit_tag "Link your profile!" %> <a href="#"
class="lbAction"
rel="deactivate"><button>Cancel</button></a>
<%= end_form_tag %>
When I go to profile_link, I get this error:
can''t convert Symbol into String
And it points to the hidden field line. What about this line doesn''t
work? The @current_fb variable?
Thanks in advance!
Dave

I found neither ''can''t convert'' nor ''can''t convert Symbol to String'' in the source of 1.2.3 rails or ruby 1.8.6. My best guess would be an empty string.

Thanks! I figured it out. There were like three different things wrong with what I posted. :) MichaelLatta wrote:> I found neither ''can''t convert'' nor ''can''t convert Symbol to String'' > in the source of 1.2.3 rails or ruby 1.8.6.

I have habtm relationships as follows... class Schoolclass < ActiveRecord::Base has_and_belongs_to_many :students, :join_table => :student_schoolclasses has_and_belongs_to_many :tests, :class_name => :teste, :join_table => :test_schoolclasses end when I access Schoolclass.find(1).students, its giving all the students of class, but when I access Schoolclass.find(1).tests, its throwing an error "can''t convert Symbol into String". Please help me. -- Posted via http://www.ruby-forum.com/.
From the code you''ve pasted, :class_name => :teste seems to be the problemFrom what I know it should be :class => :teste assuming you have all the spellings correct. Thanks & Regards, Dhruva Sagar.

:class => :teste is giving error Unknown key(s): class,
It should be :class_name => :teste only. I''m sure.
My Two models are teste.rb , schoolclass.rb
i) class Teste < ActiveRecord::Base
set_table_name "tests"
has_and_belongs_to_many :schoolclasses, :join_table =>
:test_schoolclasses, :order=>''schoolclasses.standard,
ASCII(division)
asc''
end
ii) class Schoolclass < ActiveRecord::Base
has_and_belongs_to_many :students, :join_table =>
:student_schoolclasses
has_and_belongs_to_many :tests, :class_name => :teste, :join_table
=>
:test_schoolclasses
end
What''s the problem here?
