    <p>I'm getting the error</p> <pre><code>ArgumentError in PagesController#home, wrong number of arguments (0 for 1) </code></pre> <p>but I don't know why. I have a <code>Users</code> model from Devise, and a <code>Dplan</code> model, where dplan <code>belongs_to :user</code> and a user <code>has_many :dplans</code>. I'm trying to set up my site so that you can create a new dplan on the home page. My home page view is this: </p> <pre><code>&lt;% if user_signed_in? %&gt; &lt;h1&gt;Hello &lt;%= current_user.name %&gt;! &lt;h1&gt; &lt;%= form_for @dplan do |f|%&gt; &lt;div class="field"&gt; &lt;%= f.text_area :name %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= f.submit "Submit" %&gt; &lt;/div&gt; &lt;% end %&gt; &lt;% else %&gt; &lt;h1&gt;DPlanner&lt;/h1&gt; &lt;p&gt; This is the home page for DPlanner. &lt;/p&gt; &lt;%= link_to "Sign up now!", new_user_registration_path, :class =&gt; "signup_button round" %&gt; &lt;% end %&gt; </code></pre> <p>This is dplans_controller.rb: </p> <pre><code>class DplansController &lt; ApplicationController def create @dplan = current_user.dplans.build(params[:dplan]) if @dplan.save flash[:success]="Dplan created!" redirect_to root_path else render 'pages/home' end end def destroy end end </code></pre> <p>And here is pages_controller.rb: </p> <pre><code>class PagesController &lt; ApplicationController def home @title = "Home" @dplan = Dplan.new if user_signed_in? end end </code></pre> <p>I don't understand why I'm getting this error message - the only argument needed on the page is dplan, which I define in the pages controller. Help!</p> <p>Here is dplan.rb:</p> <pre><code>class Dplan &lt; ActiveRecord::Base attr_accessible :name belongs_to :user validates :name, :presence=&gt;true, :length =&gt; { maximum =&gt; 30 } validates :user_id, :presence =&gt;true end </code></pre>

    1. COIt looks like the constructor for Dplan takes an argument. Can you include the Dplan class.

    3. COIf I comment out the 2 validates line, I get an error that says `NoMethodError in Pages#home, undefined method `dplans_path' for #<#<Class:0x00000101c45f20>:0x00000101c42320>` It looks like it has a problem with the `@dplan` in the line `form_for @dplan do...` in the home view. Is there something wrong with the line `@dplan=Dplan.new` in the `pages_controller`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
