We are using the software of Odoo 12 for enterprises.
We want to duplicate the behaviour of the add to cart button on the product pages. So we want to add a button on a different page and when you click the button you add a product to your cart and get redirected to your cart. The product is hardcoded to that button.
This is the form used on the product page template:
<form t-if="product._is_add_to_cart_possible()" action="/shop/cart/update" method="POST">
<input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>
<div class="js_product js_main_product">
<t t-placeholder="select">
<input type="hidden" class="product_id" name="product_id" t-att-value="product_variant.id"/>
<input type="hidden" class="product_template_id" name="product_template_id" t-att-value="product.id"/>
<t t-if="first_possible_combination" t-call="sale.variants">
<t t-set="ul_class" t-value="'flex-column'"/>
<t t-set="parent_combination" t-value="None"/>
</t>
<t t-else="">
<ul class="d-none js_add_cart_variants" t-att-data-attribute_exclusions="{'exclusions: []'}"/>
</t>
</t>
<t t-call="website_sale.product_price"/>
<p t-if="True" class="css_not_available_msg alert alert-warning">This combination does not exist.</p>
<a role="button" id="add_to_cart" class="btn btn-primary btn-lg mt8 js_check_product a-submit" href="#">Add to Cart</a>
</div>
</form>
The info of our product: product.id = 135 and product_template.id = 83.
I've found that the javascript responsible for the adding to the cart is called using: /web/content/.../.../web.assets_frontend.js. This is a very large file but you can check an example here: file.
Which qweb/form/js/... should I add on my custom page to add a product to my cart?
Thanks for any help, I've been stuck on this for a long time!
Edit: As @Philippe Pageau pointed out I can use some code to get the correct product already. I've tried implementing it with the form using this code (the simplest version of the form I can think of):
<t t-set="products" t-value="request.env['product.product'].search([['id', '=', 135]])"/>
<t t-foreach="products" t-as="product">
<form action="/shop/cart/update" method="POST">
<input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>
<input type="hidden" class="product_id" name="product_id" value="135"/>
<input type="hidden" class="product_template_id" name="product_template_id" value="83"/>
<a role="button" id="add_to_cart" class="btn btn-primary btn-lg mt8 js_check_product a-submit" href="#">Add to Cart</a>
</form>
</t>
But this does nothing, what am I missing?
Edit2:
Thanks to @Adan Cortes we are further now but there is still 1 problem.
Now when the user clicks on a button the products gets added to the cart with a specific quantity.
This is my code now:
<t t-set="products" t-value="request.env['product.product'].search([['id', '=', 135]])"/>
<t t-foreach="products" t-as="product">
<div id="product_detail" class="oe_website_sale">
<form action="/shop/cart/update" method="POST">
<h4 t-esc="product.name"/>
<h6 t-esc="product.price"/>
<input class="form-control" data-min="1" name="add_qty" value="1"/>
<input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>
<input type="hidden" class="product_id" name="product_id" value="135"/>
<a role="button" id="add_to_cart" class="btn btn-primary btn-lg mt8 js_check_product a-submit" href="#">Add to Cart</a>
</form>
</div>
</t>
But these are my final problems:
This code doesn't show the product price. <h6 t-esc="product.price"/> displays 0.00. So how can I display the price?
Finally is it possible to add multiple products at once using only 1 button and form?
The following code works:
<div id="product_detail" class="oe_website_sale">
<form action="/shop/cart/update" method="POST">
<input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>
<input type="hidden" class="product_id" name="product_id" value="135"/>
<a role="button" id="add_to_cart" class="btn btn-primary btn-lg mt8 js_check_product a-submit" href="#">Add to Cart</a>
</form>
</div>
But beware that using the database id makes your module unusable elsewhere. You better use xmlids.
The relevant JavaScript you were missing is at:
<path_to_v12>/addons/website_sale/static/src/js/website_sale.js
135 sAnimations.registry.WebsiteSale = sAnimations.Class.extend(ProductConfiguratorMixin, {

Edited to add
The form data is processed and dispatched by the following controller:
