@produits = Produit.order(id: :asc)

if params[:utf8]
  @ventes = Vente.date_between("#{params[:date1]}", "#{params[:date2]}")
else
  @ventes = Vente.recent
  @ventes = Vente.plivret if params[:plivret]
  @ventes = Vente.nlivret if params[:nlivret]
end
@crediteurs_customs = Vente.credit_customs_fideles if params[:credits]
#@crediteurs_clients_libre = Vente.credit_clients_libres if params[:credits]

end

# GET /ventes/1
# GET /ventes/1.json
def show

if @vente.custom_id != -1
  @cli = Custom.list.find(@vente.custom_id)
end

@ventelignes = @vente.ventelignes.select("categoriepro_id, produit_id,name,reference,qte,qtelivre,prix_u, remise,montant, ventelignes.id, ventelignes.etat").prod
@paiements_vente = @vente.paiements.list.jointure_vente.tout_paiement_pc.jointure_custom

@venteligne = Venteligne.new(:vente => @vente)

@paiement = Paiement.new(:vente => @vente, :custom => @cli)

end

def new
@vente = Vente.new
@produits = Produit.order(id: :asc)
# for p in @produits

@produits.each { |int| @vente.ventelignes.build({ :produit_id => int.id, :name => int.name }) }

end

@vente = Vente.new(vente_params)

respond_to do |format|
  if @vente.save
    format.html { redirect_to @vente, notice: 'Vente was successfully created.' }
    format.json { render :show, status: :created, location: @vente }

def destroy
@vente.destroy
respond_to do |format|
format.html { redirect_to ventes_url, notice: 'Vente was successfully destroyed.' }
format.json { head :no_content }
end
end

private
# 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: [
          :id,
          :produit_id,
          :qte,
          :remise,
          :_destroy
      ]
  )
end

end```

I can not seem to add to the database.

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

Posted in USSD APPLICATION

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```
