update join table has_many through with additional checkboxes - mysql

Question

if i dont find solution here i have no idea where i should looking for...
I know there is right, easy solution for it...but something i just dont understand.
I have 3 models...
Scheme.rb
class Scheme < ActiveRecord::Base
has_many :projects
has_many :custom_issue_field_definitions, through: :scheme_custom_issue_field_definitions
has_many :scheme_custom_issue_field_definitions
end
CustomIssueFieldDefinition.rb
class CustomIssueFieldDefinition < ActiveRecord::Base
has_many :schemes, through: :scheme_custom_issue_field_definitions
has_many :scheme_custom_issue_field_definitions
belongs_to :custom_issue_field
end
SchemeCustomIssueFieldDefinition.rb
class SchemeCustomIssueFieldDefinition < ActiveRecord::Base
belongs_to :scheme
belongs_to :custom_issue_field_definition
end
Join Model have 3 additional fields...with type: boolean.
I'd like to update scheme_custom_issue_field_definitions table. How controller and form should looks like?
Additional image:
Update:
In console i can update it like this:
a = Scheme.first
b = CustomIssueFieldDefinition.first
c = a.scheme_custom_issue_field_defintitions.find_or_create_by(custom_issue_field_definition: b)
c.update_attributes(visible: 1, reportable: 0, required: 0)
Next Update:
Now form looks like this (what is completely wrong):
<%= simple_form_for #scheme_new_custom_issue_field, url: configurations_scheme_path(#scheme), method: :put do |f| %>
<% #available_custom_issue_field_definitions.each do |custom_issue_field| %>
<tr>
<td><%= custom_issue_field.label %></td>
<td><%= f.input :visible, as: :boolean %></td>
<td><%= f.input :reportable, as: :boolean %></td>
<td><%= f.input :required, as: :boolean %></td>
</tr>
<% end %>
<%= f.button :submit, class: "btn btn-primary" %>
<% end %>
and schemes_controller
def update
#scheme = Scheme.find(params[:id])
#scheme_new_custom_issue_field = #scheme.scheme_custom_issue_field_definitions.
find_or_create_by(scheme_id: #scheme, custom_issue_field_definition_id: params[:custom_issue_field_definition_id])
if #scheme_new_custom_issue_field.update_attributes(scheme_custom_issue_field_definition_params)
flash[:success] = "Scheme has been successfully updated"
redirect_to :back
else
render :edit
end
end

If you want to create new SchemCustomIssueFieldDefinition record in the console, I suggest this alternative:
a = Scheme.first
b = CustomIssueFieldDefinition.first
c = SchemeCustomIssueFieldDefinition.find_or_initialize_by(scheme: a, custom_issue_field_definition: b)
c.assign_attributes(visible: 1, reportable: 0, required: 0)
c.save
This will save you one less query than your current example code as this will not do have an UPDATE sql.
For your form:
<%= simple_form_for #scheme, method: :patch do |f| %>
<% #available_custom_issue_field_definitions.each do |custom_issue_field| %>
<tr>
<%= f.simple_fields_for :scheme_custom_issue_field_definitions, #scheme.scheme_custom_issue_field_definitions.find_or_initialize_by(custom_issue_field_definition: custom_issue_field) do |ff| %>
<%= ff.hidden_field :id %>
<%= ff.hidden_field :scheme_id, value: #scheme.id %>
<%= ff.hidden_field :custom_issue_field_definition_id, value: custom_issue_field.id %>
<td><%= custom_issue_field.label %></td>
<td><%= ff.input :visible, as: :boolean %></td>
<td><%= ff.input :reportable, as: :boolean %></td>
<td><%= ff.input :required, as: :boolean %></td>
<% end %>
</tr>
<% end %>
<%= f.button :submit, class: "btn btn-primary" %>
<% end %>
schemes_controller.rb:
class SchemesController < ApplicationController
# ...
def update
#scheme = Scheme.find(params[:id])
if #scheme.update(scheme_params)
flash[:success] = "Scheme has been successfully updated"
redirect_to :back
else
render :edit
end
end
# ...
private
def scheme_params
# update below if you need other scheme attributes to be updated
params.require(:scheme).permit(:id, scheme_custom_issue_field_definitions_attributes: [:id, :scheme_id, :custom_issue_field_definition_id, :visible, :reportable, :required])
end
end
scheme.rb
class Scheme < ActiveRecord::Base
# ...
accepts_nested_attributes_for :scheme_custom_issue_field_definitions_attributes
# ...
