Double nested association w/ Cocoon and Polimorphism gets rejected
Clash Royale CLAN TAG#URR8PPPDouble nested association w/ Cocoon and Polimorphism gets rejected
So, I have a model Label which is polymorphic and another model Stuff which is not. A stuff can have many labels (may also called groups), and each and every one of them can also have a label. I am working with the Cocoon gem to try to add these resource on to a sigle edit/new form (the Stuff one). The problem is that when I try to update the stuff with a new group (with new labels in it), it says this Labels lables labelable must exist. I think that that's an error given becouse the first lable(group) is not yet saved to the database, so it can't give his nested lable an id. (not sure though)
Label
Stuff
Stuff
Labels lables labelable must exist
Also, is this the best way to do that? I mean, I made the label polymorphic only because I needed to save a only a string, and it would be unpractical and it would have taken database storage for nothing...
Enough talking, here's my code:
<div class="form-group">
<label>Groups:</label>
<div id="group" class="col-md-12 p-0 pl-md-3">
<%= form.fields_for :labels do |groupForm| %>
<%= render 'group_fields', f: groupForm %>
<% end %>
<div class="text-center">
<%= link_to_add_association 'Add Group', form, :labels, partial: 'group_fields', class: 'btn btn-success',
wrap_object: Proc.new { |group| group.labels.build; group } %>
</div>
</div>
</div>
that's in my _form.html.erb
<div class="nested-fields">
<div class="field form-group row">
<%= f.label :name, class: 'col-sm-1 col-form-label' %>
<div class="col-sm-10">
<%= f.text_field :name, class: 'form-control ml-2' %>
</div>
<div class="col-sm-1 p-0">
<%= link_to_remove_association "×".html_safe, f, class: 'badge badge-pill badge-danger mt-2' %>
</div>
<div class="col-12">
<div id="label" class="col-md-12 p-0 pl-md-5 pt-2">
<%= f.fields_for :labels do |labelForm| %>
<%= render 'label_fields', f: labelForm %>
<% end %>
<div class="text-center">
<%= link_to_add_association 'Add Label', f, :labels, class: 'btn btn-success' %>
</div>
</div>
</div>
</div>
</div>
that's in _group_fields.html.erb
<div class="nested-fields">
<div class="field form-group row mb-2">
<%= f.label :name, class: 'col-sm-1 col-form-label' %>
<div class="col-sm-10">
<%= f.text_field :name, class: 'form-control ml-2' %>
</div>
<div class="col-sm-1 p-0">
<%= link_to_remove_association "×".html_safe, f, class: 'badge badge-pill badge-danger mt-2' %>
</div>
</div>
</div>
and that's in my _label_fields.html.erb
class Label < ApplicationRecord
belongs_to :labelable, polymorphic: true
has_many :labels, as: :labelable, dependent: :destroy
accepts_nested_attributes_for :labels, allow_destroy: true, reject_if: proc { |att| att[:name].blank? }
end
this is my Label model
class Stuff< ApplicationRecord
has_many :labels, as: :labelable, dependent: :destroy
accepts_nested_attributes_for :labels, allow_destroy: true, reject_if: proc { |att| att[:name].blank? }
end
and this is my Stuff model
I forgot to mention that if i add only the first "layer" of label (group) without writing anithing on the labels (2nd "layer") and I submit the form (wich I can do and it updates the database as well) when i come back and edit i can actually modify the 2nd "layer" without any problems.
Anyway, thank you in advance.
