I'm working with Odoo 10, and I'm trying to modify the fleet module like the next image
We need the field "Conductor" (Driver) be unique, I mean, a vehicle only can have assigned one driver and the driver can't have more than one vehicle assigned.
I used this code:
#api.constrains('driver_id')
def _check_driver(self):
for record in self:
if record.driver_id in self:
raise ValidationError("Driver already has a vehicle assigned")
but that code doesn't work. How can I solve it?
your could apply a domain filter in the field definition as following
#definition on the fleet.vehicle model
driver_id = fields.Many2one('res.partner', index=True, required=True,
ondelete='cascade', domain=[('vehicle_id', '=', False)])
#definition on the res.partner model
vehicle_id = fields.One2many('fleet.vehicle', 'driver_id')
or as following:
#api.constrains('driver_id')
def _check_driver(self):
FleetVehicle = self.env['fleet.vehicle']
for record in self:
if record.driver_id in self:
vehicle_count = FleetVehicle.search_count(['driver_id', '=', record.driver_id])
if vehicle_count > 0:
raise ValidationError("Driver already has a vehicle assigned")
_sql_constraints = [
('driver_unique', 'UNIQUE(driver_id, )',
'The Driver has been already assigned to a vehicle !'),
]

I want to write data in dataframe to dynamodb table
item = {}
for row in datasource_archived_df_join_repartition.rdd.collect():
item['x'] = row.x
item['y'] = row.y
client.put_item( TableName='tryfail',
Item=item)
but im gettin this error
Invalid type for parameter Item.x, value: 478.2, type: '<'type 'float''>', valid types: '<'type 'dict''>'
Invalid type for parameter Item.y, value: 696- 18C 12, type: '<'type 'unicode''>', valid types: '<'type 'dict''>'
Old question, but it still comes up high in a search and hasn't been answered properly, so here we go.
When putting an item in a DynamoDB table it must be a dictionary in a particular nested form that indicates to the database engine the data type of the value for each attribute. The form looks like below. The way to think of this is that an AttributeValue is not a bare variable value but a combination of that value and its type. For example, an AttributeValue for the AlbumTitle attribute below is the dict {'S': 'Somewhat Famous'} where the 'S' indicates a string type.
response = client.put_item(
TableName='Music',
Item={
'AlbumTitle': { # <-------------- Attribute
'S': 'Somewhat Famous', # <-- Attribute Value with type string ('S')
},
'Artist': {
'S': 'No One You Know',
},
'SongTitle': {
'S': 'Call Me Today',
},
'Year': {
'N': '2021' # <----------- Note that numeric values are supplied as strings
}
}
)
In your case (assuming x and y are numbers) you might want something like this:
for row in datasource_archived_df_join_repartition.rdd.collect():
item = {
'x': {'N': str(row.x)},
'y': {'N': str(row.y)}
}
client.put_item( TableName='tryfail', Item=item)
Two things to note here: first, each item corresponds to a row, so if you are putting items in a loop you must instantiate a new one with each iteration. Second, regarding the conversion of the numeric x and y into strings, the DynamoDB docs explain that the reason the AttributeValue dict requires this is "to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations." For fuller documentation on the type system for DynamoDB take a look at this or read the Boto3 doc here since you are using Python.
The error message is indicating you are using the wrong type, it looks like you need to be using a dictionary when assigning values to item['x'] and item[y]. e.g.
item['x'] = {'value': row.x}
item['y'] = {'value': row.y}
I'm currently implementing a SBT plugin for Gatling.
One of its features will be to open the last generated report in a new browser tab from SBT.
As each run can have a different "simulation ID" (basically a simple string), I'd like to offer tab completion on simulation ids.
An example :
Running the Gatling SBT plugin will produce several folders (named from simulationId + date of report generaation) in target/gatling, for example mysim-20140204234534, myothersim-20140203124534 and yetanothersim-20140204234534.
Let's call the task lastReport.
If someone start typing lastReport my, I'd like to filter out tab-completion to only suggest mysim and myothersim.
Getting the simulation ID is a breeze, but how can help the parser and filter out suggestions so that it only suggest an existing simulation ID ?
To sum up, I'd like to do what testOnly do, in a way : I only want to suggest things that make sense in my context.
Thanks in advance for your answers,
Pierre
Edit : As I got a bit stuck after my latest tries, here is the code of my inputTask, in it's current state :
package io.gatling.sbt
import sbt._
import sbt.complete.{ DefaultParsers, Parser }
import io.gatling.sbt.Utils._
object GatlingTasks {
val lastReport = inputKey[Unit]("Open last report in browser")
val allSimulationIds = taskKey[Set[String]]("List of simulation ids found in reports folder")
val allReports = taskKey[List[Report]]("List of all reports by simulation id and timestamp")
def findAllReports(reportsFolder: File): List[Report] = {
val allDirectories = (reportsFolder ** DirectoryFilter.&&(new PatternFilter(reportFolderRegex.pattern))).get
allDirectories.map(file => (file, reportFolderRegex.findFirstMatchIn(file.getPath).get)).map {
case (file, regexMatch) => Report(file, regexMatch.group(1), regexMatch.group(2))
}.toList
}
def findAllSimulationIds(allReports: Seq[Report]): Set[String] = allReports.map(_.simulationId).distinct.toSet
def openLastReport(allReports: List[Report], allSimulationIds: Set[String]): Unit = {
def simulationIdParser(allSimulationIds: Set[String]): Parser[Option[String]] =
DefaultParsers.ID.examples(allSimulationIds, check = true).?
def filterReportsIfSimulationIdSelected(allReports: List[Report], simulationId: Option[String]): List[Report] =
simulationId match {
case Some(id) => allReports.filter(_.simulationId == id)
case None => allReports
}
Def.inputTaskDyn {
val selectedSimulationId = simulationIdParser(allSimulationIds).parsed
val filteredReports = filterReportsIfSimulationIdSelected(allReports, selectedSimulationId)
val reportsSortedByDate = filteredReports.sorted.map(_.path)
Def.task(reportsSortedByDate.headOption.foreach(file => openInBrowser((file / "index.html").toURI)))
}
}
}
Of course, openReport is called using the results of allReports and allSimulationIds tasks.
I think I'm close to a functioning input task but I'm still missing something...
Def.inputTaskDyn returns a value of type InputTask[T] and doesn't perform any side effects. The result needs to be bound to an InputKey, like lastReport. The return type of openLastReport is Unit, which means that openLastReport will construct a value that will be discarded, effectively doing nothing useful. Instead, have:
def openLastReport(...): InputTask[...] = ...
lastReport := openLastReport(...).evaluated
(Or, the implementation of openLastReport can be inlined into the right hand side of :=)
You probably don't need inputTaskDyn, but just inputTask. You only need inputTaskDyn if you need to return a task. Otherwise, use inputTask and drop the Def.task.
I'm having trouble retrieving a filtered list from google app engine datastore (using python for server side). My data entity is defined as the following
class Course_Table(db.Model):
course_name = db.StringProperty(required=True, indexed=True)
....
head_tags_1=db.ListProperty(db.Key)
So the head_tags_1 property is a list of keys (which are the keys to a different entity called Headings_1).
I'm in the Handler below to spin through my Course_Table entity to filter the courses that have a particular Headings_1 key as a member of the head_tags_1 property. However, it doesn't seem like it is retrieving anything when I know there is data there to fulfill the request since it never displays the logs below when I go back to iterate through the results of my query (below). Any ideas of what I'm doing wrong?
def get(self,level_num,h_key):
path = []
if level_num == "1":
q = Course_Table.all().filter("head_tags_1 =", h_key)
for each in q:
logging.info('going through courses with this heading name')
logging.info("course name filtered is %s ", each.course_name)
MANY MANY THANK YOUS
I assume h_key is key of headings_1, since head_tags_1 is a list, I believe what you need is IN operator. https://developers.google.com/appengine/docs/python/datastore/queries
Note: your indentation inside the for loop does not seem correct.
My bad apparently '=' for list is already check membership. Using = to check membership is working for me, can you make sure h_key is really a datastore key class?
Here is my example, the first get produces result, where the 2nd one is not
import webapp2 from google.appengine.ext import db

ekey = db.Key.from_path('C', 'ghi')
Greeting(author='xxx', x=[ckey, dkey]).put()
x = Greeting.all().filter('x =',ckey).get()
self.response.write(x and x.author or 'None')

I have a form with a SelectFieldWidget, that is currently using a static vocabularly, which is basically this:
from zope.schema.vocabulary import SimpleVocabulary, SimpleTerm
primary_contacts = SimpleVocabulary([
SimpleTerm( unicode(token), title=unicode(token.upper()), token=token ) for token in [
'one','two','three','four','five','six','seven','eight','nine','ten',
]
])
The vocabulary is assigned to the field in the form schema:
form.widget( primary_contact_person=SelectFieldWidget )
primary_contact_person = schema.List(
title = u'Nominate Primary Contact',
required = False,
value_type = schema.Choice(
vocabulary=primary_contacts,
)
)
The schema is then serialized using plone.supermodel & then deserialized when needed by the form (this is for another requirement).
The form is using a custom, handwritten template, and I'm in the process of adding the tal statements to generate the select field options. I had thought I could do this through referencing the widgets on the form, but when I do that I hit a problem:
(Pdb) self # break point in form
<Products.Five.metaclass.edit_metadata object at 0xc1ce450>
(Pdb) select = self.widgets['primary_contact_person']
(Pdb) first = [t for t in select.terms][0]
(Pdb) first.token
'one'
(Pdb) first.value
u'one'
(Pdb) first.title
(Pdb)
The title is None on the term when it's accessed through the widget. I've tried looking it up through the vocabulary:
(Pdb) select.terms.getTermByToken('one').title
(Pdb)
But again, it's None. However, it is there for terms in the original vocabulary object:
(Pdb) from my.package import primary_contacts
(Pdb) [t for t in primary_contacts][0].title
u'ONE'
So while I could use the source vocab object directly to provide the values the template needs, the plan is for this vocabulary to eventually be dynamic, at which point I would expect I'd need to interrogate the widget itself.
What am I doing wrong here, why is title not being defined?
The problem was with plone.supermodel. I should have mentioned more clearly that I'm using the serialized schema to produce the form, and I apologise for this.
Basically, plone.supermodel provides an export/import process, which can only deal with simple lists of values.
# line 263 in plone.supermodel.exportimport
term = SimpleTerm(token = encoded, value = value, title = value)
The solution was to use named vocabularies, which serializes the reference to the vocabulary rather than the vocabulary itself.
Sorry again for the lack of information that made this harder to debug.
In one of my Plone sites, I have a few dexterity models that I use to generate letters. The models are: "Model" (the base content of the letter), "Contact" (that contains the contact information, such as name, address etc) and "Merge" (which is a Model object rendered, in which we substitute some parts of the model with the recipients information).
The schema of the "Merge" object is the following:
class IMergeSchema(form.Schema):
"""
"""
title = schema.TextLine(
title=_p(u"Title"),
)
form.widget(text='plone.app.z3cform.wysiwyg.WysiwygFieldWidget')
text = schema.Text(
title=_p(u"Text"),
required=False,
)
form.widget(recipients=MultiContentTreeFieldWidget)
recipients = schema.List(
title=_('label_recipients',
default='Recipients'),
value_type=schema.Choice(
title=_('label_recipients',
default='Recipients'),
# Note that when you change the source, a plone.reload is
# not enough, as the source gets initialized on startup.
source=UUIDSourceBinder(portal_type='Contact')),
)
form.widget(model=ContentTreeFieldWidget)
form.mode(model='display')
model = schema.Choice(
title=_('label_model',
default='Model'),
source=UUIDSourceBinder(portal_type='Model'),
)
When creating a new "Merge" object, I want to have the "recipients" fields be preset with all contacts available in the folder where the new object is created.
I followed Martin Aspelli's guide to add a default value for a field: http://plone.org/products/dexterity/documentation/manual/developer-manual/reference/default-value-validator-adaptors
It works fine for text input fields, but I can't have it working for the "recipients" field. The method to generate the default values is the following (with some debug info with ugly print, but they'll be removed later ;) ):
#form.default_value(field=IMergeSchema['recipients'])
def all_recipients(data):
contacts = [x for x in data.context.contentValues()
if IContact.providedBy(x)]
paths = [u'/'.join(c.getPhysicalPath()) for c in contacts]
uids = [IUUID(c, None) for c in contacts]
print 'Contacts: %s' % contacts
print 'Paths: %s' % paths
print 'UIDs: %s' % uids
return paths
I tried to return the objects directly, their relative path (in the add view, when accessing "self.widgets['recipients'].value", I get this type of data) their UIDs but none of the solution as any effect.
I also tried to return tuples instead of lists or even generators, but still no effect at all.
The method is called for sure, as I see traces in the instance log.
I think you need to get the "int_id" of the related content. That's how dexterity relation fields store relation info::
from zope.component import getUtility
from zope.intid.interfaces import IIntIds
#form.default_value(field=IMergeSchema['recipients'])
def all_recipients(data):
contacts = [x for x in data.context.contentValues()
if IContact.providedBy(x)]
intids = getUtility(IIntIds)
# The following gets the int_id of the object and turns it into
# RelationValue
values = [RelationValue(intids.getId(c)) for c in contacts]
print 'Contacts: %s' % contacts
print 'Values: %s' % values
return values
