forms - Rails: Unable to route to edit page when a new nested item fails validation -


i have nested item creation form lies in show view of parent. in case single achievement (achievement_item) on achievements list (achievement).

everything seems work except new items fail validation. error thrown up:

routing error

no route matches {:action=>"show", :controller=>"achievements"}

try running rake routes more information on available routes.

when run rake routes forest of information. aside, should looking for? compared "show" actions of achievements , achievement_items counterparts in photo_galleries , gallery_photos (a structure got working - redirects invalid new gallery_photos edit page - i've been comparing of files side side, haven't found logical differences, isn't there aren't any), looks has same format.

i don't know begin. i'm going in controller of nested item:

def create     @achievement = achievement.find(params[:achievement_id])     @achievement_item = @achievement.achievement_items.create(params[:achievement_item])     if @achievement_item.save         redirect_to achievement_path(@achievement)     else         render "edit"     end end

commenting out render "edit" causes missing template error, @ least know i'm hitting line.

here edit page:

<h1>editing achievement item</h1>  <%= render 'form', achievement_item: @achievement_item %>  <%= link_to 'show', @achievement %> | <%= link_to 'back', achievement_path %>

it nice if such error message point toward problem is. , somebody should problems. :-)

banging out question made me find answer. in hopes saves somebody few hours of frustration, here is:

in edit page of nested item:

<%= link_to 'back', achievements_path %>

that's it. a missing plural on link wasn't using led hours of frustration.
