From the show.html.erb page I want to create a copy of the record on that page and be sent to the new.html.erb page. Rails dup method does that (and doesn't have and id or creation date), but I can't figure out how to get there.
The error I'm currently getting is this: Couldn't find Street with 'id'= pointing at the @street = Street.find(params[:id]).dup line in the streets_controller.rb. (This page has been updated with fixes to some of the problems I had. Thank you commenters.)
Part of my show.edit.erb page:
<p>
<strong>Previous Street Name:</strong>
<%= @street.previous_name %>
</p>
<p>
<strong>‘Current/Next’ Street Name:</strong>
<%= @street.current_name %>
</p>
<p>
<strong>Earliest Date for ‘Previous’ Name:</strong>
<%= @street.date_earliest %>
</p>
<p>
<strong>Latest Date for ‘Previous’ Name: </strong>
<%= @street.date_latest %>
</p>
<p>
<strong>Entry covers from cross street to cross street or similar:</strong>
<%= @street.cross_streets %>
</p>
<p>
<strong>Approximate Number of Blocks:</strong>
<%= @street.number_of_blocks %>
</p>
<p>
<strong>Length of segment:</strong>
<%= @street.extent_length.round(2) %> miles
</p>
And then some buttons on the same page:
<button type="button" class="btn btn-outline-primary" >
<%= link_to 'Edit', edit_street_path(@street) %>
</button>
<button type="button" class="btn btn-outline-primary" >
<%= link_to 'New Historic Street Entry', new_street_path %>
</button>
<%= link_to 'Duplicate This Entry', dup_street_path, :action => "dup", :id => @street.id, class: "btn btn-outline-primary" %>
The last button is my first stab at getting the dup done. The problem is now in passing the id.
And in the streets_controller.rb
def dup
@street = Street.find(params[:id]).dup
render :new
end
I finally got the route working: get 'dup_street', to: 'streets#dup'
And for completeness: new.html.erb
<p id="notice"><%= notice %></p>
<% provide(:title, 'New Historic Street Name') %>
<%= render 'form_edit', street: @street %>
<br/>
<div class="btn btn-primary active">
<%= link_to 'To List of Streets', streets_path %>
</div>
<%= link_to 'Duplicate This Entry', dup_street_path, :action => "dup", :id => @street.id, class: "btn btn-outline-primary" %>

Seems like this would be a common request, but searching here and elsewhere and looking in my several Rails books; I only find things about Rails 2 or 3, and they don't go quite for enough for me to understand how to make that work in Rails 5. To reiterate the current error is: Couldn't find Street with 'id'= and the following from better_errors:
