Question

I have this error:

undefined method `[]' for nil:NilClass

Extracted source (around line #16):

13:   <% end %>
14: 
15: <% create_url = {:url=>{:action=>"create"}} if @post.new_record? %>
16:         <% form_for @post, create_url do |t| %>
17:           <%= t.label :title, 'Virsraksts:' %><br />
18:           <%= t.text_field :title %><br />
19:           <%= t.label :content, 'Teksts:' %><br />

I am new at Ruby on Rails, so, please, help me.

This error happens when I push the edit button for post.

Answer 1

try something like this:

<% form_for([:post, @post], :url => create_url) do |t| %>
