Hi,

You can create a website form which takes all the product information which is to be created through website as inputs.All input values of the form will be available in the controller of the form action route.Then you can create a new record in the product model using create method by passing all the input values of the form

Eg:

< form action="/create_product" method="post">

   < input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>

   < div class="clearfix">

       < button type="submit" class="btn btn-primary float-right mb32 ">

           Confirm

           < span class="fa fa-long-arrow-right"/>

       < /button>

   < /div>

   < div class="row o_portal_details">

       < div class="col-lg-8">

           < div class="row">

               < div t-attf-class="form-group col-xl-6">

                   < label class="col-form-label" for="name">Name

                   < input type="text" name="name" t-attf-class="form-control"/>

               < /div>

           < /div>

       < /div>

   < /div>

< /form> 

Controller method :

@route(['/create_product], type='http', auth='user', website=True)

def form_submit(self, **post):

   product = request.env[product.template].sudo().create({

       name: post['name'],

       'field_2': post['field2'],

       ………….

   })

Hope it helps
