Rails cocoon f.fields_for not working -

-

i'm working project requires nested forms add multiple valves single order (order called rfq in case).

i error:

actionview::template::error (uninitialized constant rfq::valf):     48:   </div>     49:     50:   <div id="valves">     51:     <%= f.fields_for :valves |valve| %>     52:       <%= render 'valve_fields', f: valve %>     53:     <% end %>     54:       <%= link_to_add_association 'add valve', f, :valves %>

here's relevant part of form partial,

<%= form_for @rfq |f| %> ...   <div class="field">     <%= f.label :application %><br>     <%= f.text_field :application %>   </div>    <div id="valves">     <%= f.fields_for :valves |valve| %>       <%= render 'valve_fields', f: valve %>     <% end %>       <%= link_to_add_association 'add valve', f, :valves %>   </div>    <div class="actions">     <%= f.submit %>   </div> <% end %>

valve fields partial:

<div class="nested-fields">     <div class="field">         <%= f.label :line %>         <%= f.text_field :productline %>     </div>     <%= link_to_remove_association "remove valve", f %> </div>

rfq model:

class rfq < activerecord::base     has_many :valves     accepts_nested_attributes_for :valves, :allow_destroy => true     belongs_to :customer     has_paper_trail end

valve model:

class valve < activerecord::base     belongs_to :rfq     has_paper_trail end

thanks in advance

try specifying "valve" class name illustrated below.

class rfq < activerecord::base   has_many :valves, :class_name => "valve"   accepts_nested_attributes_for :valves, :allow_destroy => true   belongs_to :customer   has_paper_trail end

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens ...
