After I update my DC.edmx model from the database I'm getting an error during the fetching of data from my "Users" table.
The exception is attached as a screen shot for a better understanding. I just wanted to know what this exception actually saying and what is the possible fix? Any ideas would be appreciated.
var user = ctx.Users.FirstOrDefault(x => x.Email == model.Username);

I am trying to write a simple trigger on the case object to find the closest account to a given zip code. For simplicity I'll provide only the lines which are causing the error.
//This is a custom object which has all US zip codes with lat and lng info
ZipCodeGeolocation__c zipGl = [SELECT GeoLoc__Latitude__s, GeoLoc__Longitude__s
FROM ZipCodeGeolocation__c
WHERE Name = :c.Zip_Code__c
LIMIT 1];
List<Account> nearCenters = new List<Account>([SELECT Name, Email__c
FROM Account
WHERE DISTANCE (BillingAddress, GEOLOCATION( :zipGl.GeoLoc__Latitude__s, :zipGl.GeoLoc__Longitude__s), 'mi' ) < 50
ORDER BY DISTANCE (BillingAddress, GEOLOCATION( :zipGl.GeoLoc__Latitude__s, :zipGl.GeoLoc__Longitude__s), 'mi' )]);
Every time I add the "ORDER BY" clause, I get the following error:
"An unexpected error occurred. Please include this ErrorId if you contact support: 1398691353-5783 (-929716091)"
Obviously the Error Id is different every time. Has anyone seen this behavior before and what can I do to solve this issue?
Thank you
I have the following F# code attempting to get a user document from my documentdb database and it doesn't work. Is anyone else experiencing problems using the ReadDocumentAsync method? I am able to successfully to query my user documents with the CreateDocumentQuery method. Any help is greatly appreciated. I use my database and collection ids in place of the empty strings in the code snippet
let getUserDatabaseModel (documentClient : DocumentClient) originiatorId =
async {
let databaseId = ""
let collectionId = ""
let documentUri = UriFactory.CreateDocumentUri(databaseId, collectionId, originiatorId)
let! userDatabaseModel =
documentClient.ReadDocumentAsync(documentUri)
|> Async.AwaitTask
return userDatabaseModel
}
|> Async.RunSynchronously
Update
If I use the _rid instead of the id I get the data back. To clarify the ReadDocumentAsync seems to work using the _rid but throws the error below when using the id.
mscorlib: Exception has been thrown by the target of an invocation.
FSharp.Core: One or more errors occurred. Microsoft.Azure.Documents.Client:
The value 'left blank intentionally' specified for
query '$resolveFor' is invalid
I posted a while back on the documentdb github issues page, problems I was having with ReplaceDocumentAsync.
https://github.com/Azure/azure-documentdb-dotnet/issues/113
I wasn't too concerned about the fix because there was UpsertDocumentAsync. This issue seems to be related, or maybe their relation is just me! not being able to figure out what I'm doing wrong.
CreateDocumentUri needs consistent ids, either all ids or all _rids for the database, collection, and document
I am counting table rows in MVC view.
The below code was counting from a linked table but has now stoped giving me the following error:
Object reference not set to an instance of an object.
Has anyone any idea as to why this would happen?
#Model.Count(x => x.Device.VehicleReg != null)
You Device is null and throws exception
Try this:
#Model.Where(x=> x.Device != null).Count(x=> x.Device.VehicleReg)
Assuming that Model is not null, probably Device is null that's why you get the "Object reference " error
I'm about to lose my mind due to a simple Rails where query. I simply cannot understand why it does work like 10 lines ago and does not after it. I could not figure out what might be causing the problem
#userID = Token.where(:tokenCode => #tokenReceived)
##init.tokenCode=#tokenReceived+"1" #randomize algorithm required!
#init.tokenCode=#codeGenerated=generate_activation_code()
if #userID.nil?
#newToken=Token.new
#newToken.tokenCode=#codeGenerated
else
#tokenToAdd = "12"
#newToken=Token.where(:userID => "1")
#if #newToken.nil?
#newToken.tokenCode="12"
#end
end
##newToken.save
#init.save
When I make a successful JSON request to 'http://localhost:3000/inits.json' it gives me a page with tons of erros but I think the main error among those are:
<h1>
NoMethodError
in InitsController#create
</h1>
<pre>undefined method `tokenCode=' for #<ActiveRecord::Relation:0x007fc43cb40b88></pre>
What could be the reason? Am I writing the where clause all wrong?
Edit: When I activate the if clause it works. I simply believe the #newToken object is null, however it is almost impossible for me to detect why. There is a data in my Token table with userID 1.
When you do:
#newToken=Token.where(:userID => "1")
You get an ActiveRecord::Relation, but you expect an object. So simply replace it with:
#newToken=Token.where(:userID => "1").first
I am getting this error ...
Violation of PRIMARY KEY constraint 'PK_Members'. Cannot insert duplicate key in object 'dbo.Members'.
The statement has been terminated.
When I try to use the Membership and Role Providers in ASP.NET MVC. It happens when calling the GetUser method from inside the RoleProvider.
var member = System.Web.Security.Membership.GetUser(email) as Models.Member;
//var member = (
// from m in DataContext.Members
// where m.Email == email
// select m).Single();
var role = (
from r in DataContext.Roles
where r.Name == roleName
select r).Single();
member.Groups.Add(new Models.Group(role));
DataContext.SubmitChanges();
It looks like the problem is in the code
member.Groups.Add(new Models.Group(role));
Based on the error message returned by the sql, Read operation like GetUser won't throw this type of error.
I suspect it's because you are adding a group that exists already.
Maybe you should check for the existance of the role before trying to add it.
Hope this helps.
A good way to debug this is to use SQL profiler to determine what SQL code is being run against the database.
I would suspect you are trying to save a record somewhere that has the same primary key already in the database.
SQL Profiler = http://msdn.microsoft.com/en-us/library/ms181091.aspx
Are you sure you are not trying to enter a number into the PRIMARY KEY field that is already there? If it is auto_increment, just enter 0 and it will make the value of that field, the last number+1
Hope this helps :)
If the exception is an SqlException you might get its error number for duplicate records which is 2627. You might catch the exception and verify it and display and manage any error accordingly. I Hope this helps.
catch (SqlException ex)
{
if (ex.Number == 2627)
{
MessageBox.Show("This record exists: "+ex.Message, "Error");
}
else
{
MessageBox.Show(ex.Message, "Error")
}
}
I am a newbie at this but I am going to give this a try, sorry if it doesn't work for you.
I think that instead of using,
member.Groups.Add(new Models.Group(role));
You should use the following (if you are updating the database):
member.Groups.Entry(new Models.Group(role));
And if the above code doesn't work, try this (if you are adding to the database):
// First, search for the particular obj you want to insert
var checkModels = member.Groups.Find(new Models.Groups(roles));
// If the obj doesn't already exist, add it to the database
if(checkModels == null){
member.Groups.Add(new Models.Group(role));
}
// If the obj does exist already, then update it
else{
member.Groups.Entry(new Models.Group(role)).State = EntityState.Modified;
}
