Is there a way to achieve this?
i have tried to assign the entry to a local variable but it doesn't work with crudmethods.
getData() async {
String userId = 'userId';
Firestore.instance.collection('user').document(userId).snapshots();
var snapshot;
var userDocument = snapshot.data;
String _myAddress = userDocument["address"];
return Firestore.instance
.collection('letters')
.where("source Box", isEqualTo: _myAddress)
.snapshots();
}
Yes, you should be able to use a document in the query of another document.
For this, you need to create a reference for one collection and use it in another one.
The below code is an example that you can give it a try adapting further for your case, but that I believe should help you.
// Create references to the profile and orders collections
var profilesRef = db.collection("profile");
var ordersRef = db.collection("orders");
// Create a query against the collection.
var query = ordersRef.where("username", "==", ).doc("username").get();
In the documentation Perform simple and compound queries in Cloud Firestore, there is more information and example of queries that should help you.
In addition to that, this below post from the Community can provide you some insights on how to achieve this type of query as well.

i want to create Customer diary on the base of customerID that present in customer table.
In customerID field i want dropdown list having list of CustomerId's that are present in database
How can i do that ? can someone help me please
var _objAllCustomerIds = null;
using (AdventureWorksEntities context = new AdventureWorksEntities())
{
_objAllCustomerIds = context.MyCustomers.Select(customer => customer.Id).ToList();
}
//where AdventureWorksEntities is your DBcontent containing all your entities
//MyCustomers is the entities representation of your customer table
if this is in your .aspx file
then in your .aspx.cs file (assuming you're using code behind) you'd get the list of customer IDs and then bind that list to this dropdown.
Does this answer from another question help?
How to bind the selected value of a DropDownList
I have two model classes first one is "Ticket" and other is "ExpTicket" there is only one additional column/properties in ExpTicket and others properties are same in both lists. I extract the data from database in the form of ExpTicket list and then re-assign all column/properties to Ticket List except one additional column which does not exist in Ticket list.
But iam unable to assign data from "ExpTicket" list to "Ticket" list. If anyone can timely help I shall be very thankful. Following is the code which i need to convert From ExpTicket into "Ticket" List but failed. Please help.
var GetTicket = ticketRepository.ExpTicket(r => r.TicketId == TicketId).ToList();
List<Ticket> CTicket = GetTicket.ToList();
First you have:
var GetTicket = ticketRepository.ExpTicket(r => r.TicketId == TicketId).ToList();
Then make a query:
var CTickets = (from t in GetTicket
select new Ticket{field1=t.field1,field2=t.field2...}).ToList();
Or just readjust your model to use TPT (Table per type, Table per type code first) Good luck
var CTickets = new List<Ticket>();
var ExpTicket = ticketRepository.Where(r => r.TicketId == TicketId);
foreach (var ticket in ExpTicket)
{
CTickets.Add(new Ticket { TicketId = ticket.TicketId, ... and so on });
}
// CTickets is the new list of tickets
i just wanna list the list of employee names from database in the dropdown list using ice faces . can anyone suggest me how to write the query in icefaces page to get the list of employees in the database . say table name is "employee" .
Thanks in advance .
I do it like this.
in your bean call your business class
e.g:
ArrayList<SelectItem> selectEmployees = new ArrayList<SelectItem>();
ArrayList<Employee> employees = company.getEmployees(); //this one calls the EmployeeDAO to get the records from database.
for(int i = 0; i < employees.size(); i++){
selectEmployees.add(new SelectItem(employes.get(i).getId(),employees.get(i).getName));
}
now you can use selectEmployees as the value of the selectOneMenu.
