I can successfully retrieve data from my mongoDB instance but need to re-use the objectID for a depending query.
The following code seems to get my entire object but NOT the id. What am I missing?
# Perform a query and retrieve data
mongoOBj <- m$find('{"em": "test#test.com"}')
I realise this is an old question and OP has probably figured it out by now, but I think the answer should be
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{}')
instead of
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{"_id": 1}')
In the second case, the result will be a data frame containing ONLY the IDs. The first line will result in a data frame containing the queried data, including the IDs.
By default, field = '{"_id": 0}', meaning _id is not part of the output.
If you look at the documentation you see that the find method takes a field argument, where you specify the fields you want:
find(query = ’{}’, fields = ’{"_id" : 0}’, sort = ’{}’, skip = 0, limit = 0, handler = NULL, pagesize = NULL)
So in your case it will be something like
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{"_id": 1}')
FYI So the easiest way to get all fields is to do the query with field="{}". That will overwrite the default in the mongolite:: package find() arguments list.
It was driving me nuts for a little while too.

Is it possible to put a filter into the Issue model whose items are getting counted here????
issues = Student.objects.annotate(Count('issue'))
I really need to filter it so as to get the desired outcome...
If not is there a way I can be able to get count of all Issues to a particular student?
class Issue(SafeDeleteModel):
_safedelete_policy = SOFT_DELETE
borrower_id = models.ForeignKey(Student,on_delete=models.CASCADE)
book_id = models.ForeignKey(Books,on_delete=models.CASCADE)
class Student(models.Model):
school = models.ForeignKey(School, on_delete=models.CASCADE)
name = models.CharField(max_length=200)
student_id = models.CharField(max_length=20)
Yes, you can filter what items are counted with the filter=… parameter [Django-doc]. We can for example filter on the book_id with:
issues = Student.objects.annotate(
num_issues=Count(
'issue',
filter=Q(issue__book_id_id=some_book_id)
)
)
or to exclude soft deleted items, we can work with the deleted field that has been defined in your model (by the django-safedelete package):
issues = Student.objects.annotate(
num_issues=Count(
'issue',
filter=Q(issue__deleted=False)
)
)
Note: Normally one does not add a suffix _ids to a ManyToManyField field, since Django
it refers to a manager over the target objects. Therefore it should
be book, instead of book_id.
I have the following table in Lua:
local a = {orszag = {"Ausztria", "Albánia", "Azerbajdzsán"}, varos = {"Ankara", "Amszterdam", "Antwerpen"}, fiu = {"Arnold", "Andor", "Albert"}, lany = {"Anna", "Anasztázia", "Amanda"}}
I would like to do the following:
for i in a["orszag"] do etc. (for example compare all the words in the value to the user input)
But when I do so I get the following: attempt to call a table value.
So I know, it works in python for example, but is it possible somehow to do this in Lua as well?
Use
for k,v in pairs(a["orszag"]) do
I have the following ALV report generated from the RFKSLD00 program:
I need to generate a report based on the above report like this one (as part of my work):
Any ideas how to do this? I am not asking for a solution but some steps on how to achieve this.
Each line of the original report is one line of your report, you need just to adjust the sums for local currency, i.e. multiply all values by local currency rate. The yellow totals lines shouldn't confuse you, they are generated by grid, not by report.
The only thing that is missing in original report is debit and credit of balance carryforward, I suppose in the original you have already reconciliated value. To get separate values for it you need inspecting the code.
The initial step would be to declare final structure and table based on it:
TYPES: BEGIN OF ty_report,
rec_acc TYPE skont,
vendor TYPE lifnr,
...
jan_deb TYPE wrbtr,
jan_cred TYPE wrbtr,
febr_deb TYPE wrbtr,
febr_cred TYPE wrbtr,
...
acc_bal_deb TYPE wrbtr,
acc_bal_cred TYPE wrbtr,
END OF ty_report,
tt_report TYPE TABLE OF ty_report.
DATA: lt_report TYPE tt_report.
Then you only need looping original report internal table and fill your final structure, not missing currency conversion:
select single * from tcurr
into #DATA(tcurr)
where fcurr = 'EUR'
and tcurr = 'AUD'. "<- your local currency
DATA(lv_ukurs) = tcurr-ukurs.
LOOP AT orig_table INTO DATA(orig_line).
APPEND INITIAL LINE INTO lt_report ASSIGNING FIELD-SYMBOL(<fs_rep>).
MOVE-CORRESPONDING orig_line TO <fs_rep>.
CASE orig_line-monat. "<- your period
WHEN '01'.
<fs_rep>-jan_deb = orig_line-debit.
<fs_rep>-jan_cred = orig_line-credit.
WHEN '02'.
<fs_rep>-febr_deb = orig_line-debit.
<fs_rep>-febr_cred = orig_line-credit.
...
ENDCASE.
DO 30 TIMES.
ASSIGN COMPONENT sy-index OF STRUCTURE <fs_rep> TO FIELD-SYMBOL(<field>).
CHECK sy-subrc = 0.
DESCRIBE FIELD <field> TYPE DATA(TYP).
CHECK TYP = 'P'.
CALL FUNCTION 'CONVERT_TO_LOCAL_CURRENCY'
EXPORTING
DATE = sy-datum
FOREIGN_CURRENCY = 'EUR'
LOCAL_CURRENCY = 'AUD'
FOREIGN_AMOUNT = <field>
TYPE_OF_RATE = 'M'
IMPORTING
EXCHANGE_RATE = lv_ukurs
LOCAL_AMOUNT = <field>.
ENDDO.
ENDLOOP.
I recommend to name all components of your final structure ty_report the same as in original as much as possible. Thus you can maximally utilize MOVE-CORRESPONDING and avoid manual coding.
This is just quick shot and I may be missing some details and errors.
I am writing some code where I have multiple dictionaries for my data. The reason being, I have multiple core objects and multiple smaller assets and the user must be able to choose a smaller asset and have some function off in the distance run the code with the parent noted.
An example of one of the dictionaries: (I'm working in ROBLOX Lua 5.1 but the syntax for the problem should be identical)
local data = {
character = workspace.Stores.NPCs.Thom,
name = "Thom", npcId = 9,
npcDialog = workspace.Stores.NPCs.Thom.Dialog
}
local items = {
item1 = {
model = workspace.Stores.Items.Item1.Main,
npcName = "Thom",
}
}
This is my function:
local function function1(item)
if not items[item] and data[items[item[npcName]]] then return false end
end
As you can see, I try to index the dictionary using a key from another dictionary. Usually this is no problem.
local thisIsAVariable = item[item1[npcName]]
but the method I use above tries to index the data dictionary for data that is in the items dictionary.
Without a ton of local variables and clutter, is there a way to do this? I had an idea to wrap the conflicting dictionary reference in a tostring() function to separate them - would that work?
Thank you.
As I see it, your issue is that:
data[items[item[npcName]]]
is looking for data[“Thom”] ... but you do not have such a key in the data table. You have a “name” key that has a “Thom” value. You could reverse the name key and value in the data table. “Thom” = name
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
