var query = Query<Foo>.Where(foo => foo.properties.AsQueryable().Any(property => property.Name == "Foo" && property.Value.AsString == "foo1"));
var result = collection.Find(query).First();
}
calling FindFoos results in the following exception:
Unsupported where clause: Queryable.Any(Queryable.AsQueryable(foo.properties), (BsonElement property) => ((property.Name == "Foo") && (property.Value.AsString == "foo1"))).
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentException: Unsupported where clause: Queryable.Any(Queryable.AsQueryable(foo.properties), (BsonElement property) => ((property.Name == "Foo") && (property.Value.AsString == "foo1"))).
at the line:
var query = Query<Foo>.Where(foo => foo.properties.AsQueryable().Any(property => property.Name == "Foo" && property.Value.AsString == "foo1"));
I can do this query easily in the mongodb shell as:
db.Foos.find( {'properties.Foo' : 'foo1'} );
What is the correct way to do this query with Linq?
Try LINQ's SelectMany() method. It is used to flatten nested collections. Instead of using nested for loops, we can do the task in a more 'LINQ' way.
Ex given below -
Master m1 = new Master() { name = "A", lstObj = new List<obj> { new obj { i = 1, s = "C++" }, new obj { i = 1, s = "C#" }, new obj { i = 1, s = "Java" } } };
Master m2 = new Master() { name = "A", lstObj = new List<obj> { new obj { i = 4, s = "PHP" }, new obj { i = 5, s = "Ruby" }, new obj { i = 6, s = "Perl" } } };
List<Master> lstMasters = new List<Master> { m1, m2 };
var result = lstMasters.SelectMany(m => m.lstObj).Where(o => o.s == "PHP");
Just replace the Master class with your BsonDocument.

I am trying to use filter with search query. Search requset works correctly without filter. But using filter I get 400 error as response.
This is type mapping:
var mapp = new
{
mappings = new
{
posts = new
{
properties = new
{
FullText = new
{
type = "string",
analyzer = "russian"
},
Title = new
{
type = "string",
analyzer = "russian"
},
PostPubDate = new
{
type = "date"
},
Link = new
{
type = "string",
index = "not_analyzed"

RubricsIds = new
{
type = "integer"
},
ObjectsIds = new
{
type = "integer"
},
SourceId = new
{
type = "integer"
}
}
}
}
};
This is a request to index with filtered query:
string url = "http://localhost:9200/neg_collector/posts/_search";
var request = (HttpWebRequest)HttpWebRequest.Create(url);
var o = new
{
size = 20,
query = new
{
filtered = new
{
query = new
{
query_string = new
{
fields = new[] { "Title" },
query = search_query
}
},
filter = new
{
#bool = new
{
should = new
{
term = new
{
SourceId = sIds
}
}
}
}
}
}
};
request.Method = "POST";
var jsonObj = JsonConvert.SerializeObject(o);
var data = Encoding.UTF8.GetBytes(jsonObj);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
I want to use an array of integers to filter result with certain SourceId-s. But I got error 400.
What am I doing wrong? Thank you
So the problem was that this syntax was for elasticsearch 2 version (And it worked nice on another computer). Here I have ElasticSearch 5 and should use another was of filtering:
var o = new
{
size = 20,
query = new
{
#bool = new
{
must = new
{
query_string = new
{
fields = new[] { "Title" },
query = search_query
}
},
filter = new
{
terms = new
{
SourceId = new[] {10,11,12}
}
}
}
}
};

Using C# with Lambda(or some method), how can I merge different informations(from columns) of the same intituition name ? They can have some common and some different fields.
See a example below:
Have you tried the Group By instruction ?
Here is an other stackoverflow about this : Group by in LINQ
{
List<Instituition> Instituitions = new List<Instituition>() {
new Instituition { Name = "Name1", Alias = "",Area="" },
new Instituition { Name = "Name1", Alias = "Alias1",Area="" },
new Instituition { Name = "name2", Alias = "Audi" ,Area="444"},
new Instituition { Name = "Name1", Alias = "",Area="Garden" }};
var results = Instituitions.GroupBy(i => i.Name,
i => i.Alias,
(key, g) => new
{
Name = key,
Alias = g.Where(a =>a != "").FirstOrDefault(),
Area = Instituitions.Where(a=>a.Name == key && a.Area != "").Select(a=>a.Area).FirstOrDefault()
}
);
}
class Instituition
{
internal string Name;
internal string Alias;
internal string Area;

I am pretty new to MOQ and I am in learning right now. I got task that I need to write unit test But I am getting the below error which I couldn't able to find. Please anyone help me with this. Also please review the code and give me some advises if my testcase needs changes.
Expection: IAcronisService.GetActivitiesFromDate("mygroup", 5/24/2016

From your example, your setup for IAcronisService.GetActivitiesFromDate shows that it is expecting lastActivityDate of 2016-08-14T20:47:05 based on the code but the error shows that you used a different date 5/24/2016 8:33:34 PM than expected. As the moq behavior is Strict, this
Causes the mock to always throw an exception for invocations that don't have a corresponding setup.
You can make the setup a little more flexible by using It.IsAny<DateTime>()
moqAcronisService
.Setup(m => m.GetActivitiesFromDate(groupName, It.IsAny<DateTime>()))
.Returns(activitiesResponse);
or changing the behavior in your moq factory to use Default or Loose MockBehavior.
I'm experimenting with Couchbase + Xamarin.Forms trying to do a simple search, showing the results in a ListView but I've stuck. :(
Someone know how to add the rows/documents of a query in a list?
public List<Visitor> SearchRecord (string word)
{
var viewByName = db.GetView ("ByName");
viewByName.SetMap((doc, emit) => {
emit (new object[] {doc["first_name"], doc["last_name"]}, doc);
}, "2");
var visitorQuery = viewByName.CreateQuery();
visitorQuery.StartKey = new List<object> {word};
// visitorQuery.EndKey = new List<object> {word, new Dictionary<string, object>()};
visitorQuery.Limit = 100;
var visitors = visitorQuery.Run();
var visitorList = new List<Visitor> ();
foreach (var visitor in visitors) {
// visitorList.Add(visitor.Document); <-- Error.
System.Console.WriteLine(visitor.Key);
}
return visitorList;
}
I get the error messages:
Error CS1501: No overload for method Add' takes2' arguments
(CS1501) (Demo_Couchbase.Droid) Error CS1502: The best overloaded
method match for
System.Collections.Generic.List<Demo_Couchbase.Visitor>.Add(Demo_Couchbase.Visitor)'

Error CS1503: Argument#1' cannot convert Couchbase.Lite.Document'
expression to typeDemo_Couchbase.Visitor' (CS1503)
(Demo_Couchbase.Droid)
Thank you in advance for any help you can provide.
There is problem in your mapping part. You can directly cast documents on GetView.
You can try bellow code.
public List<Visitor> SearchRecord (string word)
{
var viewByName = db.GetView<Visitor>("ByName","ByName");
var visitorQuery = viewByName.CreateQuery();
visitorQuery.StartKey = new List<object> {word};
visitorQuery.Limit = 100;
var visitors = visitorQuery.Run();
var visitorList = new List<Visitor> ();
foreach (var visitor in visitors) {
visitorList.Add(visitor.Document);
System.Console.WriteLine(visitor.Key);
}
return visitorList;
}
I don't know if this is the most elegant solution though but my code works fine now.
Visitor ToRecord(Document d) {
var props = d.Properties;
return new Visitor {
Id = props["_id"].ToString(),
FirstName = (string)props["first_name"],
LastName = (string)props["last_name"],
Occupation = (string)props["occupation"],
Company = (string)props["company"],
Email = (string)props["email"],
Phone = (string)props["phone"],
Birthday = (string)props["birthday"],
LastVisit = (string)props["last_visit"],
LocalImagePath = (string)props["local_image_path"],
Type = (string)props["type"],
CreatedAt = (string)props["created_at"],
UpdatedAt = (string)props["updated_at"],
DeletedAt = (string)props["deleted_at"]
};
}
public List<Visitor> SearchRecord (string word)
{
var viewByName = db.GetView ("ByName");
viewByName.SetMap((doc, emit) => {
if ((doc.ContainsKey("type") && doc["type"].ToString() == "visitor") && (doc.ContainsKey("deleted_at") && doc["deleted_at"] == null))
emit (new [] {doc["first_name"], doc["last_name"]}, doc);
}, "2");
var visitorQuery = viewByName.CreateQuery();
visitorQuery.StartKey = word;
visitorQuery.Limit = 50;
var rows = visitorQuery.Run();
var visitorList = new List<Visitor> ();
for (int i = 0; i < rows.Count (); i++) {
var row = rows.GetRow (i);
var name = row.Document.GetProperty ("first_name").ToString ().ToLower () + " " + row.Document.GetProperty ("last_name").ToString ().ToLower ();
if (name.Contains (word))
visitorList.Add(ToRecord(row.Document));
}
return visitorList;
}
Is there a more elegant/concise way of this; I'd like to get rid of foreach loop with the WorkListItem initialization code.
var queryable = registrations.Select(
r => new
{
r.Id, r.AccountNumber, r.DateAdded, r.DateUpdated, r.Patient, r.Patient.InsuranceInfos
});
var list = queryable.ToList();
var workListItems = new List<WorkListItem>();
foreach (var anonymous in list)
{
var w = new WorkListItem
{
Id = anonymous.Id,
ClientAccountId = anonymous.AccountNumber,
DateAdded = anonymous.DateAdded,
DateUpdated = anonymous.DateUpdated,
Patient = anonymous.Patient,
InsuraceInfos = anonymous.Patient.InsuranceInfos
};
workListItems.Add(w);
}
return workListItems;
Yes you can completely cut out the "middle-man" as it were and select straight into a new WorkListItem as below:
var list = registrations.Select(r => new WorkListItem
{
Id = r.Id,
ClientAccountId = r.AccountNumber,
DateAdded = r.DateAdded,
DateUpdated = r.DateUpdated,
Patient = r.Patient,
InsuraceInfos = r.Patient.InsuranceInfos
}).ToList();
