I want to do exactly what you are saying Leonardo.
Here is my code for
education_plans_controller.rb
----------------------------
def create
@education_plan = EducationPlan.new(params[:education_plan])
# this is my sneaky way around, which I don't want to use....You'll see
what i'm doing when you see the view
# @student = Student.find(params[:student_id])
# @tutor = Tutor.find(params[:tutor_id])
# @education_plan.student = @student
# @education_plan.tutor = @tutor
respond_to do |format|
if @education_plan.save
flash[:notice] = 'EducationPlan was successfully created.'
format.html { redirect_to(@education_plan) }
format.xml { render :xml => @education_plan, :status =>
:created, :location => @education_plan }
else
format.html { render :action => "new" }
format.xml { render :xml => @education_plan.errors, :status =>
:unprocessable_entity }
end
end
end
def new
@education_plan = EducationPlan.new
@education_plan.plan_details.build
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @education_plan }
end
end
----------------------------
education_plan - new view
----------------------------
<h1>New Education Plan</h1>
<% form_for(@education_plan) do |f| %>
<%= f.error_messages %>
<div>
Enter Student OSIS: <%=text_field_tag :osis %><%= image_tag
'loading.gif', :id =>'loading', :style => 'display: none'%>
<div id="student_info"></div>
</div>
<table>
<tr>
<div>
<table>
<thead>
<tr>
<th></th><th>Code #</th><th>Start
date</th><th>Evaluation/Measurement/Assesment</th>
</tr>
</thead>
<tbody>
<% 6.times do |i| %>
<% f.fields_for :plan_details do |p| %>
<%= render :partial => 'new_detail', :object => p %>
<% end %>
<% end %>
</tbody>
</table>
</div>
<table>
<tr>
<td><%= f.label :comments %></td>
<td><%= f.text_area(:comments, :cols => 30, :rows => 4) %></td>
</tr>
</table>
<p>
<%= f.submit 'Create'%>
</p>
<% end %>
<%= link_to 'Back', education_plans_path %>
<%= observe_field(:osis, :frequency => 0.25, :update => :student_info,
:url =>{:controller => 'students', :action =>
:get_student_info},
:with => 'osis',
:before => "Element.show('loading')",
:complete => "Element.hide('loading')") %>
----------------------------
students_controller.rb
----------------------------
def get_student_info
@student = Student.find_by_osis(params[:osis])
if @student.nil?
render :text => 'Couldn\' find the student'
elsif !...@student.education_plan.nil?
render :text => 'Student already has an education plan.'
else
render :partial => true, :action => 'show'
end
end
----------------------------
students show view
----------------------------
<%=hidden_field_tag(:student_id, @student.id) %>
<%=h @student.first_name + ' ' + @student.last_name %>
----------------------------
So, with my workaround it does what I want, but then all kinds of other
problems are introduced i.e. error handling etc.
I hope this illustrates better what I'm trying to do.
Thanks!
