I use net core to api controller and Client with React.
I want get details of list opportunity after insert to DB but I do not knowHow get list ids of data added?
My Code Insert Data.
var customers = await db.Customers.Where(c =>
c.Categories.Any(cate =>
model.CustomerCategories.Contains(cate.CategoryId)
)
).ToListAsync();
foreach(var customer in customers) {
if (String.IsNullOrEmpty(model.Name)) {
opportunityName = customer.FullName;
}
var opportunity = new Opportunity {
StepId = model.StepId,
Name = opportunityName,
Email = customer.Email,
Phone = customer.Phone,
CustomerId = customer.Id,
Status = IdentityStatus.Active,
ExpectedRevenue = model.ExpectedRevenue,
Probability = model.Probability,
Notes = model.Note,
Deadline = model.Deadline,
OwnerId = OwnerId,
Reason = model.Reason,
Revenue = model.Revenue,
CompleteDate = model.CompleteDate,
};
db.Opportunities.Add(opportunity);
}
await db.SaveChangesAsync();
Keep track of the entities you are adding, call SaveChangesAsync and then inspect them afterwards. EF will have populated their keys.
Here's some psuedo-code that should illustrate the idea:
var customers = await db.Customers.Where(c =>
c.Categories.Any(cate =>
model.CustomerCategories.Contains(cate.CategoryId)
)
).ToListAsync();
var opportunities = new List<Opportunity>(customers.Count);
foreach(var customer in customers) {
if (String.IsNullOrEmpty(model.Name)) {
opportunityName = customer.FullName;
}
var opportunity = new Opportunity {
StepId = model.StepId,
Name = opportunityName,
Email = customer.Email,
Phone = customer.Phone,
CustomerId = customer.Id,
Status = IdentityStatus.Active,
ExpectedRevenue = model.ExpectedRevenue,
Probability = model.Probability,
Notes = model.Note,
Deadline = model.Deadline,
OwnerId = OwnerId,
Reason = model.Reason,
Revenue = model.Revenue,
CompleteDate = model.CompleteDate,
};
opportunities.Add(opportunity);
//db.Opportunities.Add(opportunity);
}
db.Opportunities.AddRange(opportunities);
await db.SaveChangesAsync();
//foreach (var opportunity in opportunities)
// Console.WriteLine(opportunity.YourIdPropertyHere);

That's when i need to use the Stripe API so when i need it, it will go wrong and make mistakes in the Stripe area as you can see here.
i have : v15.6.1 on Stripe.net
Where it goes wrong is here:
planservice.Create(new StripePlanCreateOptions()
to here:
PlanId = abn.PriceValueUnikId };
all the value I get by json eg userid, pric and pricId there is content in them.
[HttpPost]
public IActionResult Post([FromBody] JObject token)
{
var api = Settings.ConstName.StrinpAPIKeyTest;
StripeConfiguration.SetApiKey(api);
var chargeService = new StripeChargeService();
chargeService.ExpandBalanceTransaction = true;
chargeService.ExpandCustomer = true;
chargeService.ExpandInvoice = true;
//StripeCharge stripeCharge = chargeService.Get(api);
var customerSerive = new StripeCustomerService(api);
var subservice = new StripeSubscriptionService(api);
var planservice = new StripePlanService(api);
var pricId = (int)token.GetValue("pricid");
var pric = (int)token.GetValue("pric");
var userid = (int) Userid();
var abn = _dbContext.PriceValue.FirstOrDefault(i => i.PriceValueId == pricId || i.Price == pric);
//Finder information omkring pakken til den enkelte pakke.
var currentUser = _dbContext.Users.FirstOrDefault(i => i.UserId == userid);
if (currentUser != null)
{
if (abn != null)
{
var orderid = Settings.ValueWordsAndNumbers.OrdreValue();//Orderid
var planType = $"OrderId: {orderid} - Pris: {abn.Price} - Mdr: {abn.Months} UserId: {userid}";
planservice.Create(new StripePlanCreateOptions()//error from here
{
Amount = int.Parse(abn.Price.ToString()) * 100,
Nickname = planType,
Currency = "dkk",
Interval = "month",
IntervalCount = abn.Months,
Id = abn.PriceValueUnikId
});
var newCustomer = new StripeCustomerCreateOptions
{
SourceToken = token["id"].ToString(),
Email = token["email"].ToString(),
PlanId = abn.PriceValueUnikId,
};//error to here
var stripeCustomer = customerSerive.Create(newCustomer);
}
}
var planOptions = new StripePlanCreateOptions() {
Product = new StripePlanProductCreateOptions() {
Name = "planType"
},
Amount = int.Parse(abn.Price.ToString()) * 100,
Nickname = planType,
Currency = "dkk",
Interval = "month",
IntervalCount = abn.Months,
};
var planService = new StripePlanService();
StripePlan plan = planService.Create(planOptions);
API version to 2018-02-06 and add support for Product & Plan API
Now Product is REQUIRED.
you need past ID product or dictionary containing fields used to create a service product.
var planOptions = new StripePlanCreateOptions() {
ProductId ="Product Plan id",
Amount = int.Parse(abn.Price.ToString()) * 100,
Nickname = planType,
Currency = "dkk",
Interval = "month",
IntervalCount = abn.Months,
};
Orders are created and saved in this method
public async Task<ActionResult> FirstClassCreate(FormCollection values)
{
var order = new Order();

I need to be access the orders database and change attributes of a specific order, using the email as the Unique Identifier and search for the newest (find the newest using the Order Date where 'haspaid' = false).
using ()//Insert database context here)
{
//Search for order in the database, try using the email as the Unique Identifire and search for the newest where haspaid = false
//Change the haspaid attribute to true
var orders = from o in db.Orders
where o.Email == User.Identity.Name, o.HasPaid = false, //Newest
select o;
order.HasPaid = true;
db.Orders.SaveChanges();
//save database changes
}
If I understand you correctly, you don't know how to query the record you want to update. So you need to use the Where() to filter the record and use the Max() function to get the latest date.
var orderToBeChanged = db.Orders
.Where(o => o.HasPaid == false && o => o.Email == User.Identity.Name)
.Max(o => o.OrderDate);
I'm somewhat new to EF 6.0 so I'm pretty sure I'm doing something wrong here.
there are two questions related to the problem
what am I doing wrong here
what's the best practice to achieve this
I'm using a code first model, and used the edmx designer to design the model and relationships, the system needs to pull information periodically from a webservice and save it to a local database (SQL Lite) in a desktop application
so I get an order list from the API, when I populate and try to save Ticket, I get a duplicate key exception when trying to insert TicketSeatType -
how do I insert the ticket to dbContext, so that It doesn't try and re-insert insert TicketSeatType and TicketPriceType, I have tried setting the child object states to unchanged but it seems to be inserting
secondly, what would be the best practice to achieve this using EF ? it just looks very inefficient loading each object into memory and comparing if it exists or not
since I need to update the listing periodically, I have to check against each object in the database if it exists, then update, else insert
code:
//read session from db
if (logger.IsDebugEnabled) logger.Debug("reading session from db");
dbSession = dbContext.SessionSet.Where(x => x.Id == sessionId).FirstOrDefault();
//populate orders
List<Order> orders = (from e in ordersList
select new Order {
Id = e.OrderId,
CallCentreNotes = e.CallCentreNotes,
DoorEntryCount = e.DoorEntryCount,
DoorEntryTime = e.DoorEntryTime,
OrderDate = e.OrderDate,
SpecialInstructions = e.SpecialInstructions,
TotalValue = e.TotalValue,
//populate parent refernece
Session = dbSession
}).ToList();
//check and save order
foreach (var o in orders) {
dbOrder = dbContext.OrderSet.Where(x => x.Id == o.Id).FirstOrDefault();
if (dbOrder != null) {
dbContext.Entry(dbOrder).CurrentValues.SetValues(o);
dbContext.Entry(dbOrder).State = EntityState.Modified;
}
else {
dbContext.OrderSet.Add(o);
dbContext.Entry(o.Session).State = EntityState.Unchanged;
}
}
dbContext.SaveChanges();
//check and add ticket seat type
foreach (var o in ordersList) {
foreach (var t in o.Tickets) {
var ticketSeatType = new TicketSeatType {
Id = t.TicketSeatType.TicketSeatTypeId,
Description = t.TicketSeatType.Description
};
dbTicketSeatType = dbContext.TicketSeatTypeSet.Where(x => x.Id == ticketSeatType.Id).FirstOrDefault();
if (dbTicketSeatType != null) {
dbContext.Entry(dbTicketSeatType).CurrentValues.SetValues(ticketSeatType);
dbContext.Entry(dbTicketSeatType).State = EntityState.Modified;
}
else {
if (!dbContext.ChangeTracker.Entries<TicketSeatType>().Any(x => x.Entity.Id == ticketSeatType.Id)) {
dbContext.TicketSeatTypeSet.Add(ticketSeatType);
}
}
}
}
dbContext.SaveChanges();
//check and add ticket price type
foreach (var o in ordersList) {
foreach (var t in o.Tickets) {
var ticketPriceType = new TicketPriceType {
Id = t.TicketPriceType.TicketPriceTypeId,
SeatCount = t.TicketPriceType.SeatCount,
Description = t.TicketPriceType.Description
};
dbTicketPriceType = dbContext.TicketPriceTypeSet.Where(x => x.Id == ticketPriceType.Id).FirstOrDefault();
if (dbTicketPriceType != null) {
dbContext.Entry(dbTicketPriceType).CurrentValues.SetValues(ticketPriceType);
dbContext.Entry(dbTicketPriceType).State = EntityState.Modified;
}
else {
if (!dbContext.ChangeTracker.Entries<TicketPriceType>().Any(x => x.Entity.Id == ticketPriceType.Id)) {
dbContext.TicketPriceTypeSet.Add(ticketPriceType);
}
}
}
}
dbContext.SaveChanges();
//check and add tickets
foreach (var o in ordersList) {
dbOrder = dbContext.OrderSet.Where(x => x.Id == o.OrderId).FirstOrDefault();
foreach (var t in o.Tickets) {
var ticket = new Ticket {
Id = t.TicketId,
Quantity = t.Quantity,
TicketPrice = t.TicketPrice,
TicketPriceType = new TicketPriceType {
Id = t.TicketPriceType.TicketPriceTypeId,
Description = t.TicketPriceType.Description,
SeatCount = t.TicketPriceType.SeatCount,
},
TicketSeatType = new TicketSeatType {
Id = t.TicketSeatType.TicketSeatTypeId,
Description = t.TicketSeatType.Description
},
Order = dbOrder
};
//check from db
dbTicket = dbContext.TicketSet.Where(x => x.Id == t.TicketId).FirstOrDefault();
dbTicketSeatType = dbContext.TicketSeatTypeSet.Where(x => x.Id == t.TicketSeatType.TicketSeatTypeId).FirstOrDefault();
dbTicketPriceType = dbContext.TicketPriceTypeSet.Where(x => x.Id == t.TicketPriceType.TicketPriceTypeId).FirstOrDefault();
if (dbTicket != null) {
dbContext.Entry(dbTicket).CurrentValues.SetValues(t);
dbContext.Entry(dbTicket).State = EntityState.Modified;
dbContext.Entry(dbTicket.Order).State = EntityState.Unchanged;
dbContext.Entry(dbTicketSeatType).State = EntityState.Unchanged;
dbContext.Entry(dbTicketPriceType).State = EntityState.Unchanged;
}
else {
dbContext.TicketSet.Add(ticket);
dbContext.Entry(ticket.Order).State = EntityState.Unchanged;
dbContext.Entry(ticket.TicketSeatType).State = EntityState.Unchanged;
dbContext.Entry(ticket.TicketPriceType).State = EntityState.Unchanged;
}
}
}
dbContext.SaveChanges();
UPDATE:
Found the answer, it has to do with how EF tracks references to objects, in the above code, I was creating new entity types from the list for TicketPriceType and TicketSeatType:
foreach (var o in ordersList) {
dbOrder = dbContext.OrderSet.Where(x => x.Id == o.OrderId).FirstOrDefault();
foreach (var t in o.Tickets) {
var ticket = new Ticket {
Id = t.TicketId,
Quantity = t.Quantity,
TicketPrice = t.TicketPrice,
TicketPriceType = new TicketPriceType {
Id = t.TicketPriceType.TicketPriceTypeId,
Description = t.TicketPriceType.Description,
SeatCount = t.TicketPriceType.SeatCount,
},
TicketSeatType = new TicketSeatType {
Id = t.TicketSeatType.TicketSeatTypeId,
Description = t.TicketSeatType.Description
},
Order = dbOrder
};
....
in this case the EF wouldn't know which objects they were and try to insert them.
the solution is to read the entities from database and allocate those, so it's referencing the same entities and doesn't add new ones
foreach (var t in o.Tickets) {
//check from db
dbTicket = dbContext.TicketSet.Where(x => x.Id == t.TicketId).FirstOrDefault();
dbTicketSeatType = dbContext.TicketSeatTypeSet.Where(x => x.Id == t.TicketSeatType.TicketSeatTypeId).FirstOrDefault();
dbTicketPriceType = dbContext.TicketPriceTypeSet.Where(x => x.Id == t.TicketPriceType.TicketPriceTypeId).FirstOrDefault();
var ticket = new Ticket {
Id = t.TicketId,
Quantity = t.Quantity,
TicketPrice = t.TicketPrice,
TicketPriceType = dbTicketPriceType,
TicketSeatType = dbTicketSeatType,
Order = dbOrder
};
...}
Don't you think that you are trying to write very similar codes for defining the state of each entity?
We can handle all of these operations with a single command.
You can easily achieve this with the newly released EntityGraphOperations for Entity Framework Code First. I am the author of this product. And I have published it in the github, code-project (includes a step-by-step demonstration and a sample project is ready for downloading) and nuget. With the help of InsertOrUpdateGraph method, it will automatically set your entities as Added or Modified. And with the help of DeleteMissingEntities method, you can delete those entities which exists in the database, but not in the current collection.
// This will set the state of the main entity and all of it's navigational
// properties as `Added` or `Modified`.
context.InsertOrUpdateGraph(ticket);
By the way, I feel the need to mention that this wouldn't be the most efficient way of course. The general idea is to get the desired entity from the database and define the state of the entity. It would be as efficient as possible.
When updating the Viewers collection with a reference to a User with the Id correctly set the DB is not updated with this new reference. All other fields are updated but the collections are not updated.
var entity = new Event
{
Id = model.Id,
Name = model.Name,
Date = model.Date,
Location = model.Location,
EBroadcasters = model.Broadcasters?.Select(b => new User
{
Id = b.Id,
SkypeId = b.SkypeId,
Name = b.Name,
ServiceUrl = b.ServiceUrl
}).ToList(),
EViewers = model.Viewers?.Select(v => new User
{
Id = v.Id,
SkypeId = v.SkypeId,
Name = v.Name,
ServiceUrl = v.ServiceUrl
}).ToList()
};
_ssRepository.Events.Attach(entity);
_ssRepository.Entry(entity).State = EntityState.Modified;
// Don't think I need to do this stuff but tried everything to get it to update!!!
foreach (var b in entity.EBroadcasters)
{
_ssRepository.Users.Attach(b);
_ssRepository.Entry(b).State = EntityState.Modified;
}
foreach (var v in entity.EViewers)
{
_ssRepository.Users.Attach(b);
_ssRepository.Entry(v).State = EntityState.Modified;
}
_ssRepository.SaveChanges();
Any help would be greatly appreciated!

My EF query is supposed to be sorting by the date of the first Product in the list, but for some reason, it only sorts most of the products and some of the dates are in the wrong order.
Here's the code...
using (var context = new SalesEntities())
{
var groupedData = context.s84_Schedule.AsExpandable()
.Where(predicate)
.GroupBy(c => new { c.CustomerID, c.s84_Customer.CustomerName, c.SubdivisionID, c.s84_Subdivision.SubdivisionName, c.LotNumber })
.Select(grouped => new s84_Report_Project_POCO
{
CustomerID = grouped.Key.CustomerID,
CustomerName = grouped.Key.CustomerName,
SubdivisionID = grouped.Key.SubdivisionID,
SubdivisionName = grouped.Key.SubdivisionName,
LotNumber = grouped.Key.LotNumber,
Products = grouped.Select(x => new s84_Report_Project_Product
{
ProductID = x.ProductID,
ProductName = x.s84_Product.ProductName,
ProductDate = x.CustomerExpectedDate,
FieldRepID = x.FieldRepID,
FieldRepName = x.s84_FieldRep.FieldRepName,
InstallerID = x.InstallerID,
InstallerName = x.s84_Installer.InstallerName,
StatusID = x.StatusID,
StatusColor = x.s84_Status.StatusColor,
StatusName = x.s84_Status.StatusName,
Completed = x.Completed
}).ToList()
});
var finalList = groupedData.ToList().Where(x => x.Products.Last().Completed == false).ToList();
List<s84_Report_Project_POCO> lst = finalList.OrderBy(x => x.Products.First().ProductDate).ToList();
return lst;
}
Code seems good to me, but look at how one of the dates is out of order...
weird sorting http://www.84sales.com/weird_sort.png
Try doing the order by on the inital select
var groupedData = context.s84_Schedule.AsExpandable()
.Where(predicate)
.GroupBy(c => new { c.CustomerID,
c.s84_Customer.CustomerName,
c.SubdivisionID,
c.s84_Subdivision.SubdivisionName,
c.LotNumber })
.Select(grouped => new s84_Report_Project_POCO
{
CustomerID = grouped.Key.CustomerID,
CustomerName = grouped.Key.CustomerName,
SubdivisionID = grouped.Key.SubdivisionID,
SubdivisionName = grouped.Key.SubdivisionName,
LotNumber = grouped.Key.LotNumber,
Products = grouped
.Select(x => new s84_Report_Project_Product
{
ProductID = x.ProductID,
ProductName = x.s84_Product.ProductName,
ProductDate = x.CustomerExpectedDate,
FieldRepID = x.FieldRepID,
FieldRepName = x.s84_FieldRep.FieldRepName,
InstallerID = x.InstallerID,
InstallerName = x.s84_Installer.InstallerName,
StatusID = x.StatusID,
StatusColor = x.s84_Status.StatusColor,
StatusName = x.s84_Status.StatusName,
Completed = x.Completed
}).OrderBy(x => x.CustomerExpectedDate).ToList()
});
The problem is the .First() function, witch returns the first record, but not necessarly in date order. if you wich to order your grouped datas by date so that the First() function returns the most recent date, you'll need to order your datas before grouping them, and then REorder your results with the First()function :
using (var context = PrimaryConnection.returnNewConnection())
{
var groupedData = context.s84_Schedule.AsExpandable()
.Where(predicate)
.GroupBy(c => new { c.CustomerID, c.s84_Customer.CustomerName, c.SubdivisionID, c.s84_Subdivision.SubdivisionName, c.LotNumber })
.Select(grouped => new s84_Report_Project_POCO
{
CustomerID = grouped.Key.CustomerID,
CustomerName = grouped.Key.CustomerName,
SubdivisionID = grouped.Key.SubdivisionID,
SubdivisionName = grouped.Key.SubdivisionName,
LotNumber = grouped.Key.LotNumber,
Products = grouped
.Select(x => new s84_Report_Project_Product
{
ProductID = x.ProductID,
ProductName = x.s84_Product.ProductName,
ProductDate = x.CustomerExpectedDate,
FieldRepID = x.FieldRepID,
FieldRepName = x.s84_FieldRep.FieldRepName,
InstallerID = x.InstallerID,
InstallerName = x.s84_Installer.InstallerName,
StatusID = x.StatusID,
StatusColor = x.s84_Status.StatusColor,
StatusName = x.s84_Status.StatusName,
Completed = x.Completed
}).Orderby(t => t.CustomerExpectedDate).ToList()
});
var finalList = groupedData.ToList().Where(x => x.Products.Last().Completed == false).ToList();
List<s84_Report_Project_POCO> lst = finalList.OrderBy(x => x.Products.First().ProductDate).ToList();
All SQL queries (and hence Linq queries, when attached to a SQL database) have a random order, unless you sort them.
Products is not sorted - hence it has a random order.
You sort by Products.First(), but Products has a random order, so your sort will also be random.
Make sure Products is sorted within the query, and you should be ok.
Products = grouped.Select(....)
.OrderBy(x => x.ProductDate)
.ToList()
