    copied!<pre><code>undefined method `to_sym' for nil:NilClass </code></pre> <p>I have this error only in my edit page of my nifty_scaffold.</p> <p>This is _form.html.erb</p> <pre><code>&lt;% form_for @progress do |f| %&gt; &lt;%= f.error_messages %&gt; &lt;p&gt; &lt;%= f.label :date %&gt;&lt;br /&gt; &lt;%= f.date_select :date %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.label :description %&gt;&lt;br /&gt; &lt;%= f.text_area :description %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.label :weight %&gt;&lt;br /&gt; &lt;%= f.text_field :weight %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.label :fatpercentage %&gt;&lt;br /&gt; &lt;%= f.text_field :fatpercentage %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.label :height %&gt;&lt;br /&gt; &lt;%= f.text_field :height %&gt; &lt;/p&gt; &lt;p&gt;&lt;%= f.submit "Submit" %&gt;&lt;/p&gt; &lt;% end %&gt; </code></pre> <p>This is edit.html.erb</p> <pre><code> &lt;% title "Edit Progress" %&gt; &lt;%= render :partial =&gt; 'form' %&gt; </code></pre> <p>And this is my controller:</p> <pre><code>class ProgressesController &lt; ApplicationController def new @progress = Progress.new end def create @progress = Progress.new(params[:progress]) if @progress.save flash[:notice] = "Successfully created progress." redirect_to progresses_url else render :action =&gt; 'new' end end def edit @progress = Progress.find(params[:id]) end def update @progress = Progress.find(params[:id]) if @progress.update_attributes(params[:progress]) flash[:notice] = "Successfully updated progress." redirect_to progresses_url else render :action =&gt; 'edit' end end def index @progresses = Progress.all end end </code></pre> <p>What could be wrong? I can't seem to find my error :-S. It seems that it: - fetches the data correctly - can't insert the db-values into the "edit view" fields.</p> <p>I'm using :float, :string and :date as data types in the scaffold. </p> <p>Just for the completed post, this is my error: NoMethodError in Progresses#edit</p> <pre><code>Showing app/views/progresses/edit.html.erb where line #3 raised: undefined method `to_sym' for nil:NilClass Extracted source (around line #3): 1: &lt;% title "Edit Progress" %&gt; 2: 3: &lt;% form_for @progress do |f| %&gt; 4: &lt;%= f.error_messages %&gt; 5: &lt;p&gt; 6: &lt;%= f.label :date %&gt;&lt;br /&gt; </code></pre> <p>At line 6 the log of the code ends...</p> <p>Edit: It seems to be an error in my routes.rb. This is currently commented:</p> <pre><code> map.edit_progress "edit_progress", :controller =&gt; "progresses", :action =&gt; "edit" </code></pre> <p>when i uncomment it, it gives an error also in my index view.</p> <p>For some reason, this is called: '<a href="http://127.0.0.1:3001/progresses/1/edit" rel="nofollow noreferrer">http://127.0.0.1:3001/progresses/1/edit</a>', shouldn't it be: '<a href="http://127.0.0.1:3001/progresses/edit/1" rel="nofollow noreferrer">http://127.0.0.1:3001/progresses/edit/1</a>' ? Even though it seem's that the "edit view" is called... Perhaps this is the reason why the values aren't filled in, in my view...</p> <p>What could be my solution?</p>
