# Use callbacks to share common setup or constraints between actions.
def set_vente
@vente = Vente.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def vente_params
  params.require(:vente).permit(
      :custom_id,
      :remise,
      :date_vente,
      :etat_vente,
      ventelignes_attributes: [

I can not seem to add to the database.

I watched the episodes, but for me it's a bit special.

Hello I am working on a project that is to develop a platform. The platform will aim to monitor and records the payment transaction operations on the mobile network. I remind you that the mobile payment platform in itself already exists and is integrated to the network of a mobile operator via the USSD protocol. Do you have an idea of I should go about it

And what language used to develop.

Hi evry bady.
I have three models.
I want a form that gives the product list, just added the amount for inclusion in ventelinges.

class Produit < ActiveRecord::Base
  has_many :ventelignes
end```

```vente.rb
class Vente < ActiveRecord::Base
  has_many :ventelignes, dependent: :destroy
  has_many :produits, through: :ventelignes
  accepts_nested_attributes_for :ventelignes, allow_destroy: true
end```

```venteligne.rb
class Venteligne < ActiveRecord::Base
  belongs_to :vente
  belongs_to :produit
end```
