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

Rails
1

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 %>

30:                                       <td

nowrap=“nowrap”><%=enewsletter.title%>

31:                                       <td

32:                                       <td nowrap="nowrap">

33:                                       <td>

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")%>

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:

<%unless
enewsletter.publication_date.nil?%><%=enewsletter.publication_date.strftime("%m/%Y")%>
I still get the page We’re sorry but something went wrong.
