List<CurrentElectionService> result = new List<CurrentElectionService>();
result = oElectionsManager.GetCurrentElectionsByEId(
employeeId.StringToGuid(), planYear) as List<CurrentElectionService>;
Public class CurrentElectionService : ICurentElection
{
// Implement Interface fields here
}
The method GetCurrentElectionsByEId returns me IList<ICurentElection> and I want to cast the interface into class CurrentElectionService, but it returns null. Please help.
Why not use LINQ to perform your cast
List<CurrentElectionService> result = oElectionsManager.GetCurrentElectionsByEId(
employeeId.StringToGuid(), planYear).Cast<CurrentElectionService>().ToList();
I hope this helps.
You need to find out of which type the actual return value is. The as keywort always returns null if your actual object is not of the type you want to cast it to.
With the definition you gave you could also try this:
List<ICurentElection> result;
result = oElectionsManager.GetCurrentElectionsByEId(
employeeId.StringToGuid(), planYear) as List<ICurentElection>;

I try to save some data that it brings me from my view, which is a table, but I don't know why it throws me that error with the insert.
result of insert
this is my view:
table of view
this is my controller:
$checked_array = $_POST['id_version'];
foreach ($request['id_version'] as $key => $value) {
if (in_array($request['id_version'][$key], $checked_array))
{
$soft_instal = new Software_instalacion;
$soft_instal->id_instalacion = $instalaciones->id;
$soft_instal->id_historial = $historial->id;
$soft_instal->id_usuario = $request->id_usuario;
$soft_instal->id_version = $_POST['id_version'][$key];
$soft_instal->obs_software = $_POST['obs_software'][$key];
$soft_instal->id_tipo_venta = $_POST['id_tipo_venta'][$key];
$soft_instal->save();
}
}
id_tipo_venta seems to be an empty string which is apparently not valid.
You can try debugging what you get in :
var_dump($_POST['id_tipo_venta'][$key]);
die;
Your database field expects to receive an integer. Therefore, using the intval() function can solve your problem.
Indeed, I think your code returns an alphanumeric string.
Therefore, the code below will return 0 in all cases if no version is returned (not set, string or simply null):
$soft_instal->id_tipo_venta = intval($_POST['id_tipo_venta'][$key]);
On the other hand, intval() will always convert to int, so a decimal will be converted, example :
intval("1.1") // returns 1
intval("v1.1") // returns 0
If this is not the desired behavior, maybe you should think about changing your database type.
EDIT :
Of course, you can also set the value as null if you prefer to 0. You must allow nullable values in your database.
id_tipo_venta can not be empty, try with some number or change type column to varchar in the database
I have a Front-End application that sends me Data to update my User (updatedUser). Since I don't want to send the whole Userdata, I'm only sending the data that has changed. Now I want to Update my Userdata with the changes provided, so I'd like to know if there is a more elegant way to do this than just a list of ifs/lets. I'm quite new to kotlin, so don't expect too much from me^^
Not so elegant way:
changeData.firstname?.let { updatedUser.firstname = it }
changeData.lastname?.let { updatedUser.lastname = it }
...
Expected (doesn't work - type mismatch):
updatedUser.copy(
firstname = changeData?.firstname,
lastname = changeData?.lastname,
...)
the reason you get a type mismatch is There is a string type and a string nullable type
var variableName:String = "myData" // if you want a non nullable
var variableName:String? = "myDataThatCouldBeNull" // if you want a string that could be null
I have a object that I want to print it into string [key1=value1&key2=value2...etc] without the null value key value pair and comma into &.
So first of all i think of putting it into a map but it won't work and I don know how it work either.
val wxPayOrderObj = WxPayOrder(appid = "wx0b6dcsad20b379f1", mch_id =
"1508334851", nonce_str = UUID.randomUUID().toString(),sign = null,
body = "QQTopUp", out_trade_no = "20150806125346", total_fee = req.total_fee,
spbill_create_ip = "123.12.12.123",
trade_type = "JSAPI", openid = "oUpF8uMuAJO_M2pxb1Q9zNjWeS6o")
so the output will be
appid=wx0b6dc78d20b379f1&mch_id=150788851&nonce_str=UUID.randomUUID().toString()&
body=QQTopUp&out_trade_no=20150806125346&total_fee=req.total_fee&
spbill_create_ip=123.12.12.123&trade_type=JSAPI&openid=oUpF8uMuAJO_M2pxb1Q9zNjWeS6o
anyone please help me, thanks in advances.
I don't really get your question, but you want to convert object to string (to a format that you want)?
Override the object's toString() to return "[key1=value1&key2=value2...etc]"
example
override fun toString(){
// make sure you compute the data first
val answer = "[key1=$value1&key2=$value2...etc]"
return answer
}
The $ is used in string templates (That's directly writing the name of a variable, the value will be used later to be concatenated) with other strings)
I want to get the string character from an ObjectId object. I use pymongo.
eg: ObjectId("543b591d91b9e510a06a42e2"), I want to get "543b591d91b9e510a06a42e2".
I see the doc, It says ObjectId.toString(), ObjectId.valueOf().
So I make this code: from bson.objectid import ObjectId.
But when I use ObjectId.valueOf(), It shows:
'ObjectId' object has no attribute 'valueOf'.
How can I get it? Thanks.
ObjectId.toString() and ObjectId.valueOf() are in Mongo JavaScript API.
In Python API (with PyMongo) proper way is to use pythonic str(object_id) as you suggested in comment, see documentation on ObjectId.
ObjectId.toString() returns the string representation of the ObjectId() object.
In pymongo str(o) get a hex encoded version of ObjectId o.
Check this link.
What works for me is to "sanitize" the output so Pydantic doesn't get indigestion from an _id that is of type ObjectId...here's what works for me...
I'm converting _id to a string before returning the output...
# Get One
#router.get("/{id}")
def get_one(id):
query = {"_id": ObjectId(id)}
resp = db.my_collection.find_one(query)
if resp:
resp['_id'] = str(resp['_id'])
return resp
else:
raise HTTPException(status_code=404, detail=f"Unable to retrieve record")
Use str(ObjectId), as already mentined in the comment by #Simon.
#app.route("/api/employee", methods=['POST'])
def create_employee():
json = request.get_json()
result = employee.insert_employee(json)
return { "id": str(result.inserted_id) }
This is an old thread, but as the existing answers didn't help me:
Having run
new_object = collection.insert_one(doc)
I was able to get the ObjectID with the inserted_id property:
print(f"{new_object.inserted_id}")
In python (Pymongo) there's no inbuilt method to do it so iterate over the result you fetched from db and then typecast _id to str(_id)
result = collection.find({query})
for docs in result:
docs[_id] = str(docs[_id])
first you have to assign the Object Id value to a variable
for example:
let objectId = ObjectId("543b591d91b9e510a06a42e2");
then use the toString method like this
let id = objectId.toString();
i have an enum.
Example:
enum events
{
MOVE_UP = 0,
MOVE_DOWN,
MOVE_RIGHT,
MOVE_LEFT,
};
i want to pass particular enum value as function arguments. for example:
my method definition is
(void) invokeEvents:(enum events)events withMessage:(NSDictionary*)message;
while calling this method i am passing arguments like:
[self invokeEvents:MOVE_UP|MOVE_DOWN|MOVE_RIGHT withMessage:message;
while checking the received parameter events is value is always last value of list of MOVE_UP|MOVE_DOWN|MOVE_RIGHT values. MOVE_RIGHT 2 as per enum value.
but i want all the values like "MOVE_UP|MOVE_DOWN|MOVE_RIGHT" equal 0, 1 and 2.
how can i pass the parameter so that i can get all values.
kindly give suggestion for my problem.
Thanks in advance.
Change your enum to:
{
MOVE_NONE = 0
MOVE_UP = 1<<0,
MOVE_DOWN = 1<<1,
MOVE_RIGHT = 1<<2,
MOVE_LEFT = 1<<3,
};
So you can pass parameters exactly as you want: MOVE_UP|MOVE_DOWN|MOVE_RIGHT.
And in invokeEvents:withMessage: check
if(events & MOVE_UP)
{
}
if(events & MOVE_DOWN)
{
}
...
