[英]Sum of column entries in a model odoo11
I have a model as follows, 我有一个模型如下
class RecipeInformation(models.Model):
_name = 'model.recipe.information'
_description = 'recipe and ingredient information'
recipe_id = fields.Many2one('model.recipe', string='Recipe', required=True)
ingredient_id = fields.Many2one('model.ingredient', string='Ingredient', required=True)
quantity = fields.Integer('Quantity', required=True, default=1)
price = fields.Float('Price', required=True)
unit_of_measure = fields.Selection([('milligrams', 'Milligrams'), ('grams', 'Grams'),('kilograms', 'Kilograms')],
'Unit of Measure', default='grams',
required=True)
price_per_UoM = fields.Float('Price/UoM', compute='_calculate_price', store=True)
Cost = fields.Float('Total Cost')
@api.depends('price', 'quantity')
def _calculate_price(self):
for record in self:
record.price_per_UoM = record.price / record.quantity
return record.price_per_UoM
@api.depends('ingredient_quantity', 'price_per_UoM')
def _calculate_cost(self):
for record in self:
record.Cost += record.ingredient * record.price_per_UoM
return record.Cost
and an xml tree and form view as follows 以及xml树和表单视图,如下所示
<record id="view_form_recipe_cost" model="ir.ui.view">
<field name="name">recipe.cost.form.view</field>
<field name="model">model.recipe.information</field>
<field name="arch" type="xml">
<form string="Recipe Cost form view">
<sheet>
<group>
<field name="recipe_id"/>
<field name="ingredient_id"/>
<field name="quantity"/>
<field name="price"/>
<field name="unit_of_measure"/>
<field name="price_per_UoM"/>
</group>
</sheet>
</form>
</field>
</record>
<record id="view_tree_recipe_cost" model="ir.ui.view">
<field name="name">recipe.cost.tree.view</field>
<field name="model">model.recipe.information</field>
<field name="arch" type="xml">
<tree>
<field name="recipe_id"/>
<field name="ingredient_id"/>
<field name="quantity"/>
<field name="price"/>
<field name="unit_of_measure"/>
<field name="price_per_UoM"/>
</tree>
</field>
</record>
What I am trying to do is get the sum of all the price_perUoM
for each row entry in my model that has the same recipe name or recipe_id
and view them possibly in another split view. 我想做的是获取模型中具有相同配方名称或
recipe_id
每个行条目的所有price_perUoM
的总和,并可能在另一个拆分视图中查看它们。
so that I can have a tree view displaying all the fields and another displaying only the recipe name and total cost of that particular recipe 这样我就可以在树视图中显示所有字段,在另一个视图中仅显示该特定配方的配方名称和总成本
I am new to odoo and I would appreciate any (advice, comments) help. 我是odoo的新手,我将感谢您的任何(建议,意见)帮助。
thanks in advance 提前致谢
有一个属性名称sum =“ Total”,您可以将其应用于xml树视图,该视图显示针对特定列显示的所有记录的总和
