In a /school/1 of a restful application I would like to add a course how
is this possible?
<% form_for @course, :url => new_school_course_path(@school), :method
=>
:put do |f| %>
<p>
<b>Title</b><br />
<%= f.text_field :title %>
</p>
<p>
<b>Semester</b><br />
<%= f.text_field :semester %>
</p>
<p>
<b>Year</b><br />
<%= f.text_field :year %>
</p>
<p>
<%= f.submit "Create" %>
</p>
<% end %>
What should my school / course controller look like?

Make sure to pass in a school_id too: <%= f.hidden_field "school_id" %> Or if you don''t want to do that, you could always get the school object itself and just add a new course to it''s courses collection. @school = School.find(params[:school_id]) @school.courses.create!(params[:course]) I should warn that create! raises an ActiveRecord::RecordNotSaved exception, so unless you''re rescuing it you might want to use create instead. I don''t understand people''s obsession with initializing an object on one line, and then saving it on the next. There''s no point in doing this unless you''re changing something about the object in between!

So you can''t use it in an "if" test (whereas you can use "if @thing.save"). You can of course do "if @thing.valid?", but that''s still a slightly oblique way of determining whether or not it was saved. David -- Upcoming training by David A.

Ok I understand that you need to write @course = Course.new My question is I get an "only get, put, and delete requests are allowed error" when I try to add a course from a school show page. How do I put a form on the school show page to create a new course that links back to the school show page once the user submits the form? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

@Ellis:
In your form_for, try :html => { :method => "put" } instead of
just :method
=> :put.
@David:
I admire your book, *Ruby for Rails: Ruby techniques for Rails developers, *it
was the first and only Ruby/Rails book I have read cover to cover. Taught me
a lot of interesting things.
"
One reason, at least, is that #create always returns the instantiated
object, whether that object got saved or not. So you can''t use it in
an "if" test (whereas you can use "if @thing.save"). You can
of course
do "if @thing.valid?", but that''s still a slightly oblique
way of
determining whether or not it was saved."
But .create! raises an Exception. This exception could either be an
ActiveRecord::RecordNotSaved, or an ActiveRecord::RecordInvalid, depending
on if the model does not have or has a validate method defined on it,
respectively.
I use .create! in my code, but .save with an if works just as well :)
def create
@school = School.find(params[:school_id])
@course = @school.courses.create!(params[:course])
flash[:notice] = "Course was successfully created."
redirect_to school_course_path(@course)
rescue ActiveRecord::NotSaved, ActiveRecord::RecordInvalid => @e
flash[:notice] = "Course could not be created."
render :action => "new"
end
The @e instance variable will either be "ActiveRecord::NotSaved" or
whatever
errors are thrown from the validate method. I rescued both, just in case.

Does this code go in the School -> create action?? If so how do I create a new school in the same action!? Or is it that I should make a new action for creating a course. Then how should my <%= form_for :course ... look like in my view ? Thanks, I''m probably just over complicating the problem, but I really cannot figure this one out.

The code I gave you should go in your course new view.

Yeah it makes sense now. I dont think doing render :action => "school/show" would work in this case. Perhaps move the course new to its own page>?
