Action Controller: Exception caught

rubyonrails-talk
1

Hello All,

I am taking a programming class and I am running into some problems with a Rail program I am working on from a book called "Beginning Rails 3, Updated." The book is having me create a blog application and I get to the point where I run the rails web server. When the page loads there is a link that suppose to go to another page where I can create a new blog, in this case a "new articile." When I click on the link it takes me to a page Called "Action Controller: Exception Caught and the title of the page is "NoMethodError in Articles#new". I am still pretty new at this, and I am not sure what this means. I will list the full part of the error screen. If you need the rest, please let me know. Thank you!

NoMethodError in Articles#new

Showing C:/IS410/Programs/blog/app/views/articles/_form.html.erb where line #16 raised:

undefined method `title' for #<Article id: nil, created_at: nil, updated_at: nil>

Extracted source (around line #16):

13: 14: <div class="field"> 15: <%= f.label :title %><br /> 16: <%= f.text_field :title %> 17: </div> 18: <div class="field"> 19: <%= f.label :body %><br />

Trace of template inclusion: app/views/articles/new.html.erb

Rails.root: C:/IS410/Programs/blog

You do not have title column in your database , try generate a migration to add the missing columns

3

go to your app root folder and try running

rake db:migrate
