POActiveScaffold::ReverseAssociationRequired error for new record creation
text
Body
copied!<p>I have three models :</p> <pre><code>class LevelTwoArea < ActiveRecord::Base has_many :places, dependent: :restrict end class Place < ActiveRecord::Base belongs_to :level_two_area has_many :producers, dependent: :restrict validates_presence_of :level_two_area_id end class Producer < ActiveRecord::Base belongs_to :place validates_presence_of :place_id end </code></pre> <p>I also have a controller with an ActiveScaffold per model. </p> <p><strong>Problem is, when i want to create a new <code>Place</code>, the scaffold spits an error to the log :</strong> </p> <pre><code>ActiveScaffold::ReverseAssociationRequired (Association producers: In order to support :has_one and :has_many where the parent record is new and the child record(s) validate the presence of the parent, ActiveScaffold requires the reverse association (the belongs_to).) </code></pre> <p>I don't understand why...</p> <p>Notice that : </p> <ul> <li>Other similar scaffolds do work</li> <li><p>i can create records and use associations in the console :</p> <pre><code>>> Place.new name: 'PONVOGO', level_two_area_id: 10144 => #<Place id: nil, name: "PONVOGO", latitude: nil, longitude: nil, producers_count: nil, level_two_area_id: 10144, created_at: nil, updated_at: nil, marker: nil> >> _.save => true >> Producer.first.place.producers => [#<Producer id: 1, name: "KOFFI YAO GREGOIRE", place_id: 43, created_at: nil, updated_at: nil>] </code></pre></li> <li><p>The problem disappears when i remove the <code>has_many :producers</code>, though the association macros look perfectly normal</p></li> <li>The problem won't disappear if i remove the <code>dependent: :restrict</code> option</li> <li>i have a <code>producers_census</code> column on my <code>Place</code> model, i suspect this to mess things up but would like to have confirmation before doing heavy refactoring.
