I have a complex type, for example, a user type with such structure:
username: string,
name: string
But when I don't set the value, it stores as map with empty fields 'username' and 'name'
How to change this behaviour in Nuxeo, I just want to see the null value, if it wasn't set
I tried to add attributes nillable in schema description, but it didn't help

I have code that sets the PXDataFieldAssign value as follows:
pf = new PXDataFieldAssign<xTACProjectTask.dueDate>(someValue);
I also have a table, holding the DAC field names, such as "xTACProjectTask.dueDate". This table also has a checkbox field to determine whether to use this DAC field as a parameter.
Is there a way to not have the DAC fieldname hard-coded, and instead (maybe using a 'typeof' call?) use the results of the table query to set that field name - like the following?
pf = new PXDataFieldAssign<typeof("xTACProjectTask.dueDate")>(someValue);
or, using my query result:
pf = new PXDataFieldAssign<typeof(query.value)>(someValue);
with query.value being the value in the table holding the DAC field name?
You can create it using Type.GetType and Activator.CreateInstance. Please see the example below:
string typeName = "PX.Objects.IN.InventoryItem+descr,PX.Objects";
Type typeArgument = Type.GetType(typeName);
Type genericClass = typeof(PXDataFieldAssign<>);
Type constructedClass = genericClass.MakeGenericType(typeArgument);
object created = Activator.CreateInstance(constructedClass,new object[] { "Test Description" });
You will get the below wrapped into object in the created
i want to search a property whose type is String[]. In my repository same property have both type 'String' & 'String[]' . i want to extract only those whose type is String[]. for this i'm using below query
path=/content/flip/us/usa/en_us/home/homepage
type=cq:PageContent
1_property=imageRotate
1_property.value=0
1_property.Type=string[]
But i getting result of String property also. Is there any way to achieve this.
When you are searching for the multivalue properties you need to search with more than one value. as the type is same for both it only differs in the storage with multi valued.
Example to retrieve Multivalue property is as shown below
path=/content/geometrixx-outdoors
type=nt:unstructured
property.and=true
property=imageRotate
property.1_value=0
property.2_value=1
property.Type=string[]
XPathQuery :
/jcr:root/content/geometrixx-outdoors//element(*, nt:unstructured)
[
(#imageRotate = '0' and #imageRotate = '1')
]
I am writing a mongoose schema, and I would like to understand the properties of the same.
Here is my schema:
var UserSchema = new Schema({
name: String,
username: { type: String, required: true, index: { unique: true }},
password: { type: String, required: true, select: false }
});
Why required is not declared for `name' - ?
Why required declared?
What is select - true/false -means?
When the index - should declared any why?
Why required is not declared for `name' - ?
Answer: When a field is mandatory to fill then in that case we mention it as required. So here "name" is not required or mandatory field.
Why `required' declared?
Answer: As mentioned above, When a field is mandatory to be filled then in that case we mention it as required.
What is select - true/false -means?
Answer: This means that it will not be returned by default in the data when you fetch the document. you can specify if this path should be included or excluded from query results by default.
Schema options
When the index - should declared any why?
Answer: Index should be declared when you are searching data on that field frequently so when you create indexing on that field in that case it do not search that field in all the collections it will search value for that field using index and will return result very quickly.
How indexes work in mongodb
Here, these act as model for your project. So, required is used as validation and index is working as index over that field
Now you have two ways :
either put validation over here in schemas/models
or just manually create validation for form at frontend using JS/Jquery and then long route
Now your answers:
Name is not compulsory to be filled in. That's why no required is put over there.
when there is mandatory to fill any value for that field. Then required is used in schemas.
True/False enables or disables the usage of validation over that field. If you are using false means filling in for that field isn't compulsion at all. But using false is considered a good practice.
Index is special data structure which are used for increasing performance during read/search operations. It increases the speed of operations and are stored in memory.
whenever we have to validate the particular field, so we used required.
required: true means you must fill that field.
required: false means you may or may not fill that field, but its a good practice.
In my User Schema I have various fields with various default values. By example, see a few fields below:
acceptedStatus: {
type: String,
trim: true,
default: 'no' //possibilities (no, yes, thinkingAboutIt, yesInFuture)
}
Is there a way to quickly return the saved data for a particular field to its default value without explicitly doing it like
user.acceptedStatus = 'no';
and, if so, is there a way to return all fields that carry default values to their original status. Thanks for your help. There are times when I need to quickly do this, and didn't know if there were any methods I am missing.
One way could be that you store schema in an object, then from that object you can easily come to know what property have defaults.
I am trying to perform some logic in a CRM 2011 Custom Workflow Activity with some attributes from the calling entity. I am having an issue with determining whether a particular attribute is null or not. I have tried seemingly all combinations of GetAttributeValue and the Attributes collection, but it seems that I will always get either a Specified Cast is not Valid or Object Reference Not Set to an Instance of an Object error when there is a null value for an attribute I'm trying to access. Does anyone know the correct method for accessing an attribute that may be null? In this example, I am working with attributes of the Guid/Entity Reference type.
You can always check to see if the attributes collection contains the specific attribute that you're looking for, but you shouldn't even have to do that. All Non-nullable types (Guid, DateTime, etc) are stored as nullable types in the Attributes collection and that's probably your problem. Try something like this ( assuming late bound):
var isValid = entity.GetAttributeValue<bool?>("new_IsValid");
CRM never returns a non-nullable value. Even things that you think would be null (bool, DateTime, int, etc) are returned as their nullable equivalent. A non-nullable cast will still succeed if the value is not null, but if the value is null, it'll give you a null reference error;
object a = new bool?(true);
bool value = ((bool)a); // Works
object b = new bool?();
bool value = ((bool)b); // Null Ref Error
This syntax ended up working for me:
//if current outside counsel not null, grab GUID value
if (thisCase.lgl_outsidecounselid != null)
{
currentOCGUID = thisCase.lgl_outsidecounselid.Id;
}
//it's null, set Guid to Guid.empty
else
{
currentOCGUID = Guid.Empty;
}
