I would like to write small module that inherit sale.order.line and adding reserved lot on sale order line tree view.
under the sale.order.line module, there is the field name move_ids (stock.move , one2many) fields. I would like to create move_ids.move_line_ids.lot_id
So I tried the following code:
lot_name = fields.Char(related="move_ids.move_line_ids.lot_id", string="String")
but no luck and saw internal server error.
jooze
You can not do that, type of related field lot_name is inconsistent with lot_id.
Try to use a computed Many2many field to get all lot ids related to the current record.
Edit:
class SaleOrderLine(models.Model):
_inherit = 'sale.order.line'
lot_ids = fields.Many2many('stock.production.lot', compute='_get_lot_ids')
#api.one
#api.depends('move_ids.move_line_ids.lot_id')
def _get_lot_ids(self):
# returns the union of all lots, with duplicates removed
self.lot_ids = self.mapped('move_ids.move_line_ids.lot_id')

I am new to redis and created an index and am attempting to ingest Zeek Logging Data, create an index for multiple fields, and then search fields in that index. For the life of me, I cannot get any values to return when searching for the #orig_ip name or using JSON.GET to retried any id.* related fields.
UPDATE: I figured this out after more troubleshooting and am updating here to help anyone else struggling with this problem.
Here is my WRONG code for creating the index:
# Options for index creation
index_def = IndexDefinition(
index_type=IndexType.JSON,
prefix = ['uid:'],
score = 0.5,
score_field = 'doc_score'
)
# Schema definition
schema = (
TagField('$.orig_l2_addr', as_name='orig_mac'),
TagField('$.id.orig_h', as_name='orig_ip'), #Wrong field path
TagField('$.id.resp_h', as_name='resp_ip'), #Wrong field path
NumericField('$.orig_bytes', as_name='orig_bytes'),
NumericField('$.resp_bytes', as_name='resp_bytes'),
NumericField('$.ts', as_name='timestamp')
)
r.ft('py_conn_idx').create_index(schema, definition = index_def)
Here is the result I kept getting with the above WRONG schema (no results)
search_result4 = r.ft('py_conn_idx').search(Query('#orig_ip:{192\.168\.210\.27}'))
Results for "#orig_ip:{192\.168\.210\.27}":
0
UPDATE: Working schema definition:
So it turns out even though Zeek is only using the . in field names vice using it to create an object, but the . in the field names was the culprit in my query failures. I needed to access the fields for the index as follows:
# Schema definition
schema = (
TagField('$.orig_l2_addr', as_name='orig_mac'),
TagField('$.["id.orig_h"]', as_name='orig_ip'), #Fixed field reference
TagField('$.["id.resp_h"]', as_name='resp_ip'), #Fixed field reference
NumericField('$.orig_bytes', as_name='orig_bytes'),
NumericField('$.resp_bytes', as_name='resp_bytes'),
NumericField('$.ts', as_name='timestamp')
)
After recreating the index with this schema, I get results with my query:
Results for "#orig_ip:{192\.168\.210\.27}":
Document {'id': 'uid:CPvYfTI4Zb1Afp2l5',....
Thanks to this stackoverflow question for finally walking me to the cause of my troubles: How to get objects value if its name contains dots?
Putting this answer here so this question gets marked as having one. See the updated question/code above!
Consider the following mapping for a document in ES.
class MyDoc(elasticseach_dsl.Document):
id_info = Object(IdInfo)
class IdInfo(elasticseach_dsl.InnerDoc):
id = Keyword()
type = Keyword()
Using elasticsearch-dsl, there are 2 ways of retrieving a document (that I am interested in):
Using MyDoc.search().query().execute(), that yields Hit objects
Using MyDoc.get(), that yields a MyDoc object
Here is the issue I am experiencing:
When I retrieve the same document from ES, and that document is missing, for example, the type field, I get different behaviours:
When using search(): doc being a Hit object, accessing doc.type raises a KeyError
When using get(): doc being a MyDoc object, accessing doc.type simply returns None
To workaround this discrepancy, I would like to convert a Hit instance to a MyDoc instance, so that I can always use the doc.type syntax without any errors being raised.
How can I do that?
Alternatively, is there a way that I could access Hit instances with the same behaviour as MyDoc instances?
dict_hit = hit.to_dict()
doc = YourDocument(**dict_hit)
doc.property1 # you can access the property here
I know it is a bit awkward and annoying, it used to work with versions below 6.
I found a workaround, if you take the dictionary coming out from elasticsearch response you can then ask the document class to interpret it like the following.
query = MyDoc.search()
response = query.execute()
my_doc = MyDoc.from_es(response.hits.hits[0])
We were facing this situation. In our case, is was due to the index name in the Index subclass to configure Document indices. Our model looked more or les like this:
class MyDoc(Document):
my_field = Keyword()
class Index:
name = "my-doc-v1-*"
This way, when querying for documents in indexes that match that name (for example "my-doc-v1-2022-07"), hits are automatically instantianted as MyDoc objects.
Now we have started to generate 'v2' indices, named like "my-doc-v2--000001", and then hits were not being populated as MyDoc objects.
For that to happen, we had to change Index.name to my-doc-*. That way, documents from both 'v1' and 'v2' indices are always populated automatically by the library, since they match the Index.name expression.
Ok
i have this class in my model :
i want to get the agencys value which is a many to many on this class and store them in a list or array . Agency which store agency_id with the id of my class on a seprate table.
Agency has it's own tabel as well
class GPSpecial(BaseModel):
hotel = models.ForeignKey('Hotel')
rooms = models.ManyToManyField('Room')
agencys = models.ManyToManyField('Agency')
You can make it a bit more compact by using the flat=True parameter:
agencys_spe = list(GPSpecial.objects.values_list('agencys', flat=True))
The list(..) part is not necessary: without it, you have a QuerySet that contains the ids, and the query is postponed. By using list(..) we force the data into a list (and the query is executed).
It is possible that multiple GPSpecial objects have a common Agency, in that case it will be repeated. We can use the .distinct() function to prevent that:
agencys_spe = list(GPSpecial.objects.values_list('agencys', flat=True).distinct())
If you are however interested in the Agency objects, for example of GPSpecials that satisfy a certain predicate, you better query the Agency objects directly, like for example:
agencies = Agency.objects.filter(gpspecial__is_active=True).distinct()
will produce all Agency objects for which a GPSpecial object exists where is_active is set to True.
I think i found the answer to my question:
agencys_sp = GPSpecial.objects.filter(agencys=32,is_active=True).values_list('agencys')
agencys_spe = [i[0] for i in agencys_sp]
With Django/Haystack/SOLR, I'd like to be able to restrict the result of a search to those records within a particular range of django_ids. Getting these IDs is not a problem, but trying to filter by them produces some unexpected effects. The code looks like this (extraneous code trimmed for clarity):
def view_results(request,arg):
# django_ids list is first calculated using arg...
sqs = SearchQuerySet().facet('example_facet') # STEP_1
sqs = sqs.filter(django_id__in=django_ids) # STEP_2
view = search_view_factory(
view_class=SearchView,
template='search/search-results.html',
searchqueryset=sqs,
form_class=FacetedSearchForm
)
return view(request)
At the point marked STEP_1 I get all the database records. At STEP_2 the records are successfully narrowed down to the number I'd expect for that list of django_ids. The problem comes when the search results are displayed in cases where the user has specified a search term in the form. Rather than returning all records from STEP_2 which match the term, I get all records from STEP_2 plus all from STEP_1 which match the term.
Presumably, therefore, I need to override one/some of the methods in for SearchView in haystack/views.py, but what? Can anyone suggest a means of achieving what is required here?
After a bit more thought, I found a way around this. In the code above, the problem was occurring in the view = search_view_factory... line, so I needed to create my own SearchView class and override the get_results(self) method in order to apply the filtering after the search has been run with the user's search terms. The result is code along these lines:
class MySearchView(SearchView):
def get_results(self):
search = self.form.search()
# The ID I need for the database search is at the end of the URL,
# but this may have some search parameters on and need cleaning up.
view_id = self.request.path.split("/")[-1]
view_query = MyView.objects.filter(id=view_id.split("&")[0])
# At this point the django_ids of the required objects can be found.
if len(view_query) > 0:
view_item = view_query.__getitem__(0)
django_ids = []
for thing in view_item.things.all():
django_ids.append(thing.id)
search = search.filter_and(django_id__in=django_ids)
return search
Using search.filter_and rather than search.filter at the end was another thing which turned out to be essential, but which didn't do what I needed when the filtering was being performed before getting to the SearchView.
Background: Project is a Data Import utility for importing data from tsv files into a EF5 DB through DbContext.
Problem: I need to do a lookup for ForeignKeys while doing the import. I have a way to do that but the retrieval if the ID is not functioning.
So I have a TSV file example will be
Code Name MyFKTableId
codevalue namevalue select * from MyFKTable where Code = 'SE'
So when I process the file and Find a '...Id' column I know I need to do a lookup to find the FK The '...' is always the entity type so this is super simple. The problem I have is that I don't have access to the properties of the results of foundEntity
string childEntity = column.Substring(0, column.Length - 2);
DbEntityEntry recordType = myContext.Entry(childEntity.GetEntityOfReflectedType());
DbSqlQuery foundEntity = myContext.Set(recordType.Entity.GetType()).SqlQuery(dr[column])
Any suggestion would be appreciated. I need to keep this generic so we can't use known type casting. The Id Property accessible from IBaseEntity so I can cast that, but all other entity types must be not be fixed
Note: The SQL in the MyFKTableId value is not a requirement. If there is a better option allowing to get away from SqlQuery() I would be open to suggestions.
SOLVED:
Ok What I did was create a Class called IdClass that only has a Guid Property for Id. Modified my sql to only return the Id. Then implemented the SqlQuery(sql) call on the Database rather than the Set([Type]).SqlQuery(sql) like so.
IdClass x = ImportFactory.AuthoringContext.Database.SqlQuery<IdClass>(sql).FirstOrDefault();
