Installation
============

It's advisable to install 'web_widget_numeric_step' to have a better usability on touch screens.

Configuration
=============

Create or edit a new view and use the new widget called 'one2many_product_picker'.
You need to define the view fields. The view must be of ``form`` type.


Widget options:
~~~~~~~~~~~~~~~

* groups > Array of dictionaries -> Declare the groups

    * name -> The group name
    * string -> The text displayed
    * domain -> Forced domain to use
    * order -> The order

        * name -> The field name to order
        * asc -> Flag to use 'asc' order

    * records_per_page > Integer -> Used to control the load more behaviour (16 by default)
    * active -> Boolean -> Select the default group to use ('false' by default = 'All' group)

* currency_field > Model field used to format monetary values ('currency_id' by default)
* field_map > Dictionary:

    * product -> The field that represent the product (`product_id` by default)
    * name -> The field that represent a name ('name' by default)
    * product_uom -> The field that represent a product_uom ('product_uom' by default)
    * product_uom_qty -> The field that represent a product_uom_qty ('product_uom_qty' by default)
    * price_unit -> The field that represent a price_unit ('price_unit' by default)
    * discount -> The field that represent a discount ('discount' by default)

* search > Array of dictionaries (defines to use name_search by default)

    * name -> The name to display
    * domain -> The domain to use

        * $search -> Replaces it with the current value of the searchbox
        * $number_search -> Replaces all the leaf with the current value of the searchbox as a number

    * name_search_value -> Enables the use of 'name_search' instead of 'search_read' and defines the value to search ('$search' by default)
    * operator -> Operator used in 'name_search' ('ilike' by default)

* edit_discount > Enable/Disable discount edits (False by default)
* edit_price > Enable/Disable price edits (True by default)
* show_discount > Enable/Disable display discount (False by default)
* show_subtotal > Enable/Disable show subtotal (True by default)
* auto_save > Enable/Disable auto save (False by default)
* auto_save_delay > The time (in milliseconds) to wait after the last interaction before launching the autosave (1500 by default)
* all_domain > The domain used in 'All' section ([] by default)

  If using auto save feature, you should keep in mind that the "Save" and "Discard" buttons
  will lose part of its functionality as the document will be saved every time you
  modify/create a record with the widget.

* ignore_warning > Enable/Disable display onchange warnings (False by default)
* instant_search > Enable/Disable instant search mode (False by default)
* trigger_refresh_fields > Fields in the main record that dispatch a widget refresh (["partner_id", "currency_id"] by default)
* auto_focus > Keep the focus on the search box after performing a search (True by default)

All widget options are optional.
Notice that you can call '_' method to use translations. This only can be used with this widget.

Example:

.. code::

    options="{'search': [{'name': _('Starts With'), 'domain': [('name', '=like', '$search%')]}], 'groups': [{'name': 'cheap', 'string': _('Cheap'), 'domain': [('list_price', '<', 10.0)], 'field_map': { 'product': 'my_product_id' }}]}"


Default context:
~~~~~~~~~~~~~~~~

The widget sends a defaults context with the 'search_read' request:

    * active_search_group_name > Contains the name of the active search group

        * 'all' > Is the hard-coded name for the 'All' group
        * 'main_lines' > Is the hard-coded name for the 'Lines' group

    * active_search_involved_fields > Contains an array of dictionaries with the fields used with the searchbox content

        * 'type' > Can be 'text' or 'number'
        * 'field' > The field name
        * 'oper' > The operator used


Examples:
~~~~~~~~~

This is an example that uses the 'sale.order.line' fields:

.. code:: xml

    <field
        name="order_line"
        attrs="{'readonly': [('state', 'in', ('done','cancel'))]}"
        nolabel="1"
        mode="form"
        widget="one2many_product_picker"
        options="{'search': [{'name': 'Test', 'domain': [['name', 'ilike', '$search']]}] ,'edit_discount': True, 'show_discount': True, 'groups': [{'name': 'desk', 'string': _('Desks'), 'domain': [('name', 'ilike', '%desk%')], 'order': [{'name': 'id', 'asc': true}]}, {'name': 'chair', 'string': _('Chairs'), 'domain': [('name', 'ilike', '%chair%')]}]}"
    >
        <form>
            <field name="state" invisible="1" />
            <field name="display_type" invisible="1" />
            <field name="currency_id" invisible="1" />
            <field name="discount" widget="numeric_step" options="{'max': 100}" invisible="1"/>
            <field name="price_unit" widget="numeric_step" invisible="1"/>
            <field name="name" invisible="1" />
            <field name="product_id" invisible="1" />
            <field name="order_id" invisible="1"/>
            <field name="product_uom_qty" class="mb-1" widget="numeric_step" context="{
                'partner_id': parent.partner_id,
                'quantity': product_uom_qty,
                'pricelist': parent.pricelist_id,
                'uom': product_uom,
                'company_id': parent.company_id
            }" />
            <field name="product_uom" force_save="1" attrs="{
                'readonly': [('state', 'in', ('sale','done', 'cancel'))],
                'required': [('display_type', '=', False)],
            }" context="{'company_id': parent.company_id}" class="mb-2" options="{'no_open': True, 'no_create': True, 'no_edit': True}" />
        </form>
    </field>

** In this example we don't use 'field_map' option because the default match with the sale.order.line field names.

Other example for 'purchase.order.line' fields:

.. code:: xml

    <field
        name="order_line"
        attrs="{'readonly': [('state', 'in', ('done','cancel'))]}"
        nolabel="1"
        widget="one2many_product_picker"
        mode="form"
        options="{'search': [{'name': _('Name'), 'domain': [['name', 'ilike', '$search']]}, {'name': _('Price'), 'domain': [['list_price', '=', $number_search]]}], 'field_map': {'product_uom_qty': 'product_qty'}, 'groups': [{'name': _('Desk'), 'domain': [['name', 'ilike', 'desk']], 'order': {'name': 'id', 'asc': true}}, {'name': _('Chairs'), 'domain': [['name', 'ilike', 'chair']]}]}"
    >
        <form>
            <field name="name" invisible="1" />
            <field name="product_id" invisible="1" />
            <field name="price_unit" invisible="1"  />
            <field name="currency_id" invisible="1" />
            <field name="order_id" invisible="1" />
            <field name="date_planned" class="mb-1" />
            <field name="product_qty" class="mb-1" widget="numeric_step" required="1" />
            <field name="product_uom" class="mb-2" options="{'no_open': True, 'no_create': True, 'no_edit': True}" />
        </form>
    </field>


Boostrap Modifications:
~~~~~~~~~~~~~~~~~~~~~~~

The product picker view container have a custom media queries space adding a new screen size called 'xxl' (>= 1440px) and modifies the columns to have 24 instead of 12.
This means that you can use "col-xxl-" inside the product picker view container.

Usage
=====

When you change the value of a field and switch to edit another record, the
changes will be applied to the previous record without having to click on
accept changes.

Known issues / Roadmap
======================

* Translations in the xml 'options' attribute of the field that use the widget can't be exported automatically to be translated
* The product card animations can be improved. Currently the card is recreated, so we lost some elements to apply correct effects
* sale.order onchanges that affects to "order_line" subfields will be ommitted to increase the performance
