I have multiple Many2many fields but I'm getting the following error:
relation stream doesn't exist,undefined-table
I cannot find where this error is occurring. Can someone help me fix this error?
class College(models.Model):
_name = 'module5_college'
_description = 'College Info'
_rec_name = 'clg'
clg = fields.Char("College Name")
uni = fields.Char("Affiliated to")
cou = fields.Many2many('module5_stream',string="Stream")
class Stream(models.Model):
_name = 'module5_stream'
_description = 'Stream info'
_rec_name = 'cou'
cou = fields.Selection([
('BTECH', 'BTECH'),
('MTECH', 'MTECH'),
('MCA', 'MCA')],"Stream")
cou_mode = fields.Selection([
('Regular','Regular'),
('Lateral','Lateral'),
('Distance','Distance')],"Course Mode")
sem_no = fields.Integer("No of semesters")
# full_score = fields.Integer(compute='score_calc',string="Score")
sem = fields.Many2many('module5_sem',"Semesters")
class Semester(models.Model):
_name = 'module5_sem'
_rec_name = 'id'
sem_no = fields.Char("Semester No")
sub = fields.Many2many('module5_subject',"Subjects")
You have to follow this example because this is the way to create many2many field:
employees_ids = fields.many2many('Employees.Employees', 'tasks_employees_rel', 'task_id', 'employee_id', 'Employees assigned to task')
To give you a better example.
A employee can be assigned to many tasks
A task can be assigned to many employees
So you have a many2many relation, so that means that you have to create a new table containing both keys.

I have a model with multiple fields being checked for uniqueness:
class AudQuestionList(BaseTimeStampModel):
aud_ques_list_id = models.AutoField(primary_key=True,...
aud_ques_list_num = models.CharField(max_length=26,...
aud_ques_list_doc_type = models.ForeignKey(DocType,...
short_text = models.CharField(max_length=55,...
aud_scope_standards = models.ForeignKey(ScopeStandard, ...
aud_freqency = models.ForeignKey(AuditFrequency, ...
aud_process = models.ForeignKey(AuditProcesses, ...
unique_together = [['aud_scope_standards', 'aud_freqency', 'aud_process',],]
My model form is as described below:
class CreateAudQuestionListForm(forms.ModelForm):
class Meta:
model = AudQuestionList
fields = ('aud_ques_list_doc_type', 'aud_scope_standards', 'aud_freqency', 'aud_process', 'short_text', ...
def validate_unique(self):
try:
self.instance.validate_unique()
except ValidationError:
self._update_errors({'aud_scope_standards': _('Record exists for the combination of key values.')})
The scenario works perfectly well, only that the field names (labels) itself are missing from the message.
Is there a way to add the field names to the message above, say something like:
Record exists for the combination of key fields + %(field_labels)s.
I have two odoo 12 models,(biblio.location and biblio.book),
-the model "biblio.book" contains a boolean "disponibile" set to true by defaul.
-the model "biblio.location" have a many2one field references to model "biblio.book".
i want the value of the boolean "disponible" in biblio.book to be changed automatically (change also in database) when a new instance of biblio.location is created, in other way when we rent(location) a book we must change disponibility in model book to FALSE.
i tried "computed field, #api.onchange and #api.depends" and nothing works for me, please help me in this issue and i want to know de difference between those three mehods.thank you
class book(models.Model):
_name = 'biblio.book'
_description = 'All books'

self._setup_related_full(model)

KeyError: 'biblio' - - -
OK, for this to work the way you want it you need to set up a foreign key in your biblio.book model.
book_location = fields.Many2one('biblio.location', string='Book Location')
Then you can do your computed field
disponible = field.Boolean(compute='_disponible', string='Available for Loan', default=False)
#api.model
def _disponible(self):
for book in self:
book.disponible = True if book.book_location else False
You don't want to set this as storable as you want it to check every time that the field is called. If you set it to storable it will only compute when the record is created.
I am trying to create a one-to-one mapping using Pony ORM.
class ApplierIngress(ApplierObjectMapper.db.Entity):
correlation_id = orm.PrimaryKey(str)
ticket_number = orm.Required(str)
username = orm.Required(str)
status = orm.Required(str)
request_date = orm.Required(datetime)
class ApplierResult(ApplierObjectMapper.db.Entity):
correlation_id = orm.Required(ApplierIngress)
result = orm.Required(orm.LongStr)
request_date = orm.Required(datetime)
It throws error while generating the mapping
pony.orm.core.ERDiagramError: Reverse attribute for ApplierResult.correlation_id not found
I want correlation_id in ApplierResult table be the foreign key referencing to correlation_id in ApplierIngress table
Please let me know what am I doing wrong?
As error said you need to specify reverse attribute. Entities is not just Tables.
class ApplierIngress(ApplierObjectMapper.db.Entity):
correlation_id = orm.PrimaryKey(str)
ticket_number = orm.Required(str)
username = orm.Required(str)
status = orm.Required(str)
request_date = orm.Required(datetime)
result_id = orm.Optional('ApplierResult') # this attribute should be added
class ApplierResult(ApplierObjectMapper.db.Entity):
correlation_id = orm.Required(ApplierIngress)
result = orm.Required(orm.LongStr)
request_date = orm.Required(datetime)
Since this class is not yet declared you should use it as string or lambda
result_id = orm.Optional('ApplierResult')
result_id = orm.Optional(lambda: ApplierResult)

I am wondering if I can do select() on sub_query.
I am able to do join sub_query with any peewee.Model. But when I wrote a sub_query and I wanted to just group by with one of the column
e.g. sub_query.select(sub_query.c.column_1, fn.COUNT(sub_query.c.column2)alias('col2_count')).group_by(sub_query.c.column_1)
query was not nested and was giving SQL syntax error.
(Can't reveal the code)
(I have done alias() on sub_query)
Edit
Example:
class Product(Model):
id = PrimaryKeyField()
name = CharField()
created_date = DateField()
class Part(Model):
id = PrimaryKeyField()
product = ForeignKeyField(Product)
name = CharField()
class ProductError(Model):
id = PrimaryKeyField()
product = ForeignKeyField(Product)
note = CharField()
class PartError(Model):
id = PrimaryKeyField()
part = ForeignKeyField(Part)
error = ForeignKeyField(ErrorMaster)
Here Product can have general error and
parts can have specific error which are predefined in ErrorMaster
I just want to know count of product which have errors against total products date wise. (error is product error or error in any part)
So sub_query is something like
sub_q = Product.select(
Product.created_date,
Product.id.alias('product_id'),
fn.IF(# checks if product has error
ProductError.is_null(True), if no product error check part error
fn.IF(fn.COUNT(PartError.id) == 0, 0, 1), # checks if error count > 0 then there is error in part
1
).alias('is_error')
).join(Part, on=Product.id == Part.product)
.join(ProductError, JOIN_LEFT_OUTER, on=Product.id == ProductError.product)
.join(PartError, JOIN_LEFT_OUTER, on=PartError.part == Part.id)
.where(Product.created_date.between(from_date, to_date))
.group_by(Product.id).alias('some_alias')
# below does not work but I can do this in sql
query = sub_q.select(sub_q.c.created_date,
fn.COUNT(sub_q.c.product_id).alias('total_products'),
fn.SUM(sub_q.c.is_error).alias('product_with_errors'))
.group_by(sub_q.c.created_date)
