Get model data in a controller

Hi everyone,

I am feeling kind of stupid, but nevertheless here is my problem:

I defined a model class:


class MealType(models.Model):
_name = 'event_participation.meal_type'

name = fields.Char(string="Name", required=True)
event_id = fields.Many2one('event.event', string="Event")
cost = fields.Float(string="Additional Cost")

def get_all_meal_types(self):
return self.search([])

Now I have a controller in which I want to get all MealType records from the database to display them.


import models

class ExtendedSaleController(main.website_sale):

def checkout_values(self, data=None):
if not data:
cr, uid, context, registry = request.cr, request.uid, request.context, request.registry
values = super(ExtendedSaleController, self).checkout_values()

#retrieve meal types

values["meals"] = meals

      return values

I tried several things to get the entries but nothing worked:

meal = models.MealType()
meals = models.MealType.get_all_meal_types(self)
meals = models.MealType.search([])
meals = meal.search([])  

 What am I missing?

Thanks for your help!

orm_meals = registry.get('event_participation.meal_type') 

get the IDs of all MealType records:

meal_ids = orm_meals.search(cr, SUPERUSER_ID, [], context=context) 

and get the complete records as objects:

meals = orm_meals.browse(cr, SUPERUSER_ID, meal_ids, context)

From within a controller, you can access ORM models using http.request.env

In your case:

MealType = http.request.env['event_participation.meal_type']
mealtypes = MealType.search([])

The thing is that in controllers you access the models and their methods using the registry like self.pool in the old api.

you can manage those data as like below into your controller.

def checkout_values(self, data=None):

if not data:

cr, uid, context, registry = request.cr, request.uid, request.context, request.registry

values = super(ExtendedSaleController, self).checkout_values()

#retrieve meal types

values["meals"] =registry['event_participation.meal_type'].search([])

return values
