ActionView::Template::Error (undefined method `strftime' for nil:NilClass)

[yatta20]

Hello, I'm a newbie. I need help resolving this issue. I recently added a pdf to the newsletter admin section of the website and now I can no longer view page 2 of the list of pdf's. Nor can I login to see the newsletters as a student. I'm using Ruby 1.9.3, Rails 3.2.1.

Here's the information from the log file.

ActionView::Template::Error (undefined method `strftime' for nil:NilClass):

    28:         <%- locals = {:enewsletter => enewsletter} %>

    29:         <td nowrap="nowrap" class='enewsletter_name'><%= enewsletter.subscription.title %></td>

    30:                                       <td nowrap="nowrap"><%=enewsletter.title%></td>

    31:                                       <td nowrap="nowrap"><%=enewsletter.publication_date.strftime("%m/%Y")%></td>

    32:                                       <td nowrap="nowrap"> <%=enewsletter.require_ama_disclaimer%></td>

    33:                                       <td>

    34:                   <%#= link_to("Edit Release", edit_admin_release_path(release), edit_admin_release_path(release)) %> &nbsp;

Hi, you can see the error in this log:

ActionView::Template::Error (undefined method `strftime' for nil:NilClass):

nil.strftime("%m/%Y") doesn't exists

    31:                                       <td nowrap="nowrap"><%=enewsletter.publication_date.strftime("%m/%Y")%></td>

enewsletter.publication_date is nil

The message says that enewsletter.publication_date is nil. Check the database to make sure that all instances have a valid date for this field.  you should add a validation to the model to prevent creating a row with a nil value.

I replaced line 31 with the following text: <td nowrap="nowrap"><%unless enewsletter.publication_date.nil?%><%=enewsletter.publication_date.strftime("%m/%Y")%></td>

I still get the page We're sorry but something went wrong.
