I dont follow the operation

# <% for @task in @project.tasks %>
#   <%= error_messages_for :task %>
#   <% fields_for "task[]" do |f| %>
#     <p><%= f.text_field :name %></p>
#   <% end %>
# <% end %>

when you create a @task. Does that mean we could create instance variables on templates as well cuz normally while iterating its just
<% for task in @project.tasks %>


and the second thing that I don't follow is the
<% fields_for "task[]" do |f| %>

what does that do. I do understand the concept of the fields_for but I dont get the "task[]" bit.

I would greatly appreciate any explanation on this. Excuse me if this seems suprisingly silly.

I changed my update function like this:

  def update
    @project = Project.find(params[:id])
    @project.attributes = params[:project]
    @project.agreementfile.attributes = params[:agreementfile]

    respond_to do |format|
      if @project.valid? && @project.agreementfile.valid
        @project.save!
        @project.agreementfile.save!
        flash[:notice] = 'Project was successfully updated.'
        format.html { redirect_to(@project) }
        format.xml  { head yikesk }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @project.errors, :status => :unprocessable_entity }
      end
    end
  end

but when I do update it says
Unknown action
No action responded to 1

Please let me know what I am doing wrong in update function

I am facing the following issue:

I have two models named: Project and AgreementFile
Every Project can have only one agreement file
So they share following relationships

class Project < ActiveRecord::Base
  belongs_to :agreementfile
end

class Agreementfile < ActiveRecord::Base
  has_one :project
 
  def sow_file=(input_data)
    self.name = input_data.original_filename
    self.content_type = input_data.content_type.chomp
    self.content = input_data.read
  end

end


I want to create agreementfile in the same view as project new
New is working for me but edit do not

In edit.html.erb file of project view I did following

<h1>Editing project</h1>

<%= error_messages_for :project, :agreementfile %>

<% form_for(:project, @project, :url => {:action => 'update'}, :html => { :multipart => true }) do |f| %>

    <p>
    <b>Name</b><br />
    <%= f.text_field :name %>
  </p>
   
  <p>
    <b>Budget</b><br />
    <%= f.text_field  :budget %>
  </p>

  <p>
    <b>Billable count</b><br />
    <%= f.text_field :billable_count %>
  </p>
   

<% fields_for(:agreementfile, @project.agreementfile) do |i| %>
    <p>
      <b>Upload file</b>
      <%= i.file_field :sow_file %>
     </p>
   <% end %>

  <p>
    <%= submit_tag "Update" %>
  </p>

<% end %>

<%= link_to 'Show', @project %> |
<%= link_to 'Back', projects_path %>


But still I found the view do not show me upload image file name in file_field of corresponding to "Upload file"

Requirement: During the edit of particular project all the fields corresponding to that project should be pre-filled. User can change the value of any field and click "Update" . The new values should then replace the old values.
So the first step itself populating the old values of project in edit form is not working. Please help me how to go about.

I am very new to Rails, and have following structure to take care of to update 2 models with one form.

:user and :user_profile.

User Model
class User < ActiveRecord::Base
has_one :user_profile
end

UserProfile Model
class UserProfile < ActiveRecord::Base
  belongs_to :user
  belongs_to :country
  belongs_to :community
  belongs_to :occupation
end


------------------------------The VIEW
          <div>
<% form_for :user do |form|%>
  <%= error_messages_for :user %>
  <table width="80%" border="0" align="center" cellpadding="3" cellspacing="0">
    <tr>
    <td width="25%" align="left"><strong>Maiden&nbsp;Last&nbsp;Name&nbsp;:</strong></td>
    <td><%= form.text_field :maiden_last_name %></td>
    </tr>
   
    <tr>
    <td width="25%" align="left"><strong>Birth Date :</strong></td>
    <td><%= form.date_select :birth_date, :start_year => 1940 %></td>
    </tr>

    <tr>
    <td width="25%" align="left"><strong>Maritial Status</strong></td>
    <td><%= form.check_box :married %></td>
    </tr>
   
    <tr>
    <td align="left"><strong>Occupation&nbsp:</strong></td>
    <td><label>
    <%=  collection_select :user, :occupation_id, Occupation.find(:all), :id, :occupation,    {:prompt => true} %>
      </label></td>
    </tr>

      <tr>
      <td align="left"><strong>Community&nbsp:</strong></td>
      <td><label>
       <%=  collection_select :user, :community_id, Community.find(:all), :id, :name, {:prompt => true} %>
            </label></td>
    </tr>

     <tr>
     <td width="25%" align="left"><strong>Marriage&nbsp;Anniversary&nbsp;Date&nbsp;:</strong></td>
     <td><%= form.date_select :marriage_anniversary_date, :start_year => 1940 %></td>
     </tr>
     
     
<tr>
<td><label>
<%= submit_tag "Join", :class => "button1" %>
</label></td>
</tr>
</table>
<% end%>
</div>


#user_controller, tellusmore action is called
#with provided :id=>@user.id, from previous page submit
...which saves few entries of both "users" and "user_profiles" tables.
#-----------------------And this is the Controller
def tellusmore
    if request.post? and params[:user]
     
      @user = User.find(params[:id], :include=>"user_profile")
      @user_profile=UserProfile.new
     
      @community = Community.find_by_id(params[:user_profile][:community_id])
      @user_profile.community_id = @community.id
      @occupation = Occupation.find_by_id(params[:user_profile][:occupation_id])
      @user_profile.occupation_id = @occupation.id
 
     
      @user.user_profile = @user_profile
     
       if @user.save
         flash[:notice]= "Step Over"
         redirect_to :action=>'login'
       else
         @user.reset_form_password
      end
    end
  end




    Please help me save these entries, into users and user_profiles using the single template.........tellusmore

Out of these -
married, maiden_last_name, birth_date belong to users table rest belongs to user_profiles table.

I know from database design point of view this isn't normalized but this is just a test case for me.

What should I do with the update method?

Thank you.

I have the following view:

  <% form_for :question, :url => { :action => 'create' } do |f| %>
  <% f.text_field :name %>
  <% f.text_area :description %>
<div id="options">
  <label>Options:</label>
  <!-- Needs to be ajaxified-->
  <% question.options.each_with_index do |option, index|%>
    <% fields_for "options[#{index}]", option do |f| %>
      <p><%= f.text_field :name, :size => 20 %></p>
    <% end %>
  <% end %>
</div>
<div id="factors">
  <label>Factors:</label>
  <!-- Needs to be ajaxified-->
  <% question.factors.each_with_index do |factor, index|%>
    <% fields_for "factors[#{index}]", factor do |f| %>
      <p><%= f.text_field :name, :size => 20 %></p>
    <% end %>
  <% end %>
</div>

Without factors it works fine, but putting factors into the form leads to rails putting both options and factors into the Option model, and neither into the Factor model.

Any thoughts?

Thanks

This will create a new comment. Try just removing that line and see if everything works.

This tutorial only supports editing multiple comments. Creating them in the same form is worthy of its own tutorial which someday I may get around to writing...

So the hash representing the group of comments would have to have a set of params for each of the entities' comments in the model.

I'm just not sure I'm doing it the right way.

@comment = @entity.comments.build(params[:comment])

Not sure what you're doing here, but params[:comment] is a hash of all the other submitted comments. Not just one.

"@entity.comments.each { |c| c.attributes = params[:comment][c.id.to_s]}"? This seems to be about where the "1=" is generated.
