Why does the second line give an error?
items = serializer.DeserializeObject(json)
value = items ["key"]
Error: Type 'object' does not support slicing. (BCE0048)
I tried various ways to indicate that "items" is a dictionary, to no avail.
Solution:
items as Dictionary [of string, object] = serializer.DeserializeObject(json)

Hi I am trying to extract a value from a Netsuite hash inside custom fields, and some others, which typically look like this - `
"custbody_delivery_ticket_number"=>
{
"script_id"=>"custbody_delivery_ticket_number",
"internal_id"=>"2701",
"type"=>"platformCore:DateCustomFieldRef",
"attributes"=> {
"value"=>"123abc"
}
}` and want the value of it inside of attributes.
Have tried many different ways, but one in particular -
delivery_ticket_number: "#{netsuite_sales_orders.custom_field_list.custom_fields.select['custbody_nef_meter_ticket_number']['attributes']['value']}",
throws error for class Enumerator, NoMethodError: undefined method `[]' for #Enumerator:0x00005589ec778730 which indicates may be getting close, but doing something wrong.
If anyone has any idea how to get values from these kind of hashes?
(Am told by the system admin that it is the correct custbody identifier)
Many Thanks
Eventually fixed this, grabbing Netsuite custom fields with a select of script_id by name,and map as below:
delivery_date:netsuite_sales_order.custom_fields_list.custom_fields.select { |field| field.script_id == 'custbody_delivery_date' }.map { |field| field.value }.first
First selecting the script_id by unique name, then mapping to the value. Was able to get any custom field like this, preferable as they can move and might not have the same index if use an index to grab them, fetching an incorrect value. This way ensures getting the correct data even if the item is moved up or down in the custom fields list.
Thanks for everyones help!
I'm getting this error when trying to build the app:
<unknown>:0: error: cannot assign value of type 'Array<_>' to type 'Array'
but Xcode is not indicating a specific line or class for the failure.
If I could understand the difference between
Array<_>
&
Array
it may help me locate the issue.
When you app is crashing, than you can turn on All Exceptions for Debug breakpoint. This should stop on the line where the crash appears.
You find this in Xcode on the Left Panel-> BreakPoint Navigator.
Than press the + in the bottome left corner and Add Exception Breakpoint.
It looks like that you overwrite an array with an array that has a specific value definition. Good Luck :)
A generic argument clause is enclosed in angle brackets ( < > )
< generic argument list >
You can replace a type parameter with a type argument that is itself a specialized version of a generic type.For example, you can replace the type parameter T in Array < T > with a specialized version of an array, Array< Int > , Array< String >, to form an array whose elements are themselves array of integers / Strings
Regarding xour code Snippet the fix is:
u should define it with the right value ... userTweetsArray : [String] = String . or remove the : [String] because setting the value defines already the object and type :)
I don't like answering my own questions but for the sake of closure
I had this line of code
var userTweetsArray : Array = [String]()
I never actually used it. Once I removed that line the error had gone.
The error was caused by assigning an array of a type in this case String to an Array of no type.
So difference is Array<_> is an array of a type and Array is not.
for an http get request's query string ?text=&index=10, how one can generate NSURLQueryItem for first key 'text' with empty value? Or does above kind of query string generation not supported by NSURLComponents ?
Actually earlier what I am trying to accomplish is creating a category on NSDictionary that will return array of NSURLQueryItems after parsing through its key-value pairs. For some keys like 'text', I am passing [NSNull null] as value and so unable to generate the needed NSURLQueryItems array. But then specifying #"" as value in the key for NSDictionary and also suggested by #Alladinian in the comment above the problem has been solved.
I have the below code which uses a method. When I try to assign the Field Symbol value [Type ANY] to the return parameter RO_TAB [Type Ref to Data], I am getting an error message OBJECTS_MOVE_NOT SUPPORTED [Conversion of type "l" to type "g" not supported.].
The issue is happening after a BW system upgrade along with which we also moved to ABAP objects. The code executes perfectly in the older version of ABAP.
The dump occurs in the below line:
RO_TAB = <lf_storage>.
I have no idea why.
method GET_LU_STORAGE_FOR_ODS.
* IMPORTS
* IF_ODS TYPE RSODSTECH
* IF_ODS_TABLE_TYPE TYPE ZODS_TAB_TYPE
* RETURNS
* RO_TAB TYPE REF TO DATA
FIELD-SYMBOLS:
<lf_storage> TYPE ANY.
DATA:
lf_index TYPE SY-TABIX,
lf_sindex TYPE STRING,
lf_name TYPE STRING.
lf_index = GET_LU_STORAGE_INDEX(
IF_ODS = IF_ODS
IF_ODS_TABLE_TYPE = IF_ODS_TABLE_TYPE ).
lf_sindex = lf_index.
CONCATENATE
'MO_LU_DATA_'
lf_sindex
INTO lf_name.
ASSIGN lf_name TO <lf_storage>.
RO_TAB = <lf_storage>.
endmethod.
You need to create a data object first, using the CREATE DATA statement. Then you can ASSIGN a field symbol to work with the dynamically created data object. There's an example in the online manual. A field symbol is not a reference, it simply places the variable assigned to it in its position. You're effectively trying to move a string (which is what lf_name is) to a reference variable, and that won't work.
You cannot assign a variable of type STRING to a variable of type REF TO DATA.
The following code snippet shows how it should be done.
DATA: lf_name TYPE string.
DATA: lo_tab TYPE REF TO DATA.
FIELD-SYMBOLS: <lf_name> TYPE string.
lf_name = 'test'.
GET REFERENCE OF lf_name INTO lo_tab.
*lf_name = lo_tab. "this is not allowed
ASSIGN lo_tab->* TO <lf_name>.
So in your case it would be sufficient to define a field symbol.
FIELD-SYMBOLS: <lf_name> TYPE STRING.
then assign the contents referenced by RO_TAB to this field symbol.
ASSIGN ro_tab->* TO <lf_name>.
and finally do the concatenation.
CONCATENATE
'MO_LU_DATA_'
lf_index
INTO <lf_name>.
That's all! No further assignments should be required.
How about just this?
lf_sindex = lf_index.
CONCATENATE
'MO_LU_DATA_'
lf_sindex
INTO RO_TAB.
I'm getting the error Enumeration yielded no results while doing:
IEnumerable<Proxy> pxys = this._ticket.AllProxies.Where(p => p.IfBusy.Equals(false));
The reason you would get that error message is one of 2 reasons, either this._ticket.AllProxies contains no items (e.g. it is an empty collection) or none of the proxies in the collection have a value of false for their IfBusy property.
