How to pass an array to js button click in phalcon volt template engine

Question

I am passing an associative array from my controller to my view and then iterating it on the template engine

 <tbody class="text-center">
                        {% for inv in inv_list %}
                            <tr>
                                <td><input type="checkbox" id="vehicle1" name="vehicle1" value="{{ inv['supplier_invoice_number'] }}"></td>
                                <td>{{ inv['contract_id'] }}</td>
                                <td>{{ inv['supplier_invoice_number'] }}</td>
                                <td>{{ inv['final_payable_amount'] }}</td>
                                <td>{{ inv['markup_value'] }}</td>
                                <td>{{ inv['markup_type'] }}</td>
                                <td>{{ inv['buyer_price'] }}</td>
                                <td><button class="btn btn-success" onclick="generateInvoice('{{ inv }}')">Invoice</button></td>
                                
                                <td><button class="btn btn-success">Invoice Email</button></td>

                            </tr>
                        {% endfor %}
                    </tbody>

Like above.I want to pass the value of the object in the onclick method,but its giving an error

Array to string conversion

.How to solve this.Please help me out

Answer 1

This Error Array to string conversion means tat you try to print an array. In your case inv is an array. I think that you need only to pass the id like onclick="generateInvoice('{{ inv['contract_id'] }}')" or a other unique value from your inc array.
