I am a Scalatra beginner and I have the following route:
get("/todos") {
contentType = formats("json")
val userid : Int = params.getOrElse("userid", halt(400)).toInt
val limit : Int = params.getOrElse("limit", "0").toInt
val offset : Int = params.getOrElse("offset", "0").toInt
if(limit != 0 && offset != 0)
from(TodoDb.todos)(todo => where(todo => todo.userid == userid) select(todo)).toList
else {
from(TodoDb.todos)(todo => where(todo => todo.userid == userid) select(todo) orderBy(todo.modified)).page(offset, limit).toList
}
}
I can't compile it, I got the following error messages:
[info] Compiling 1 Scala source to /home/coelho/www/p.zomg.hu/gfmwa-todo-app/target/scala-2.10/classes...

I learn from here: http://squeryl.org/selects.html and here: http://squeryl.org/pagination.html
I can't see parameter type information on these pages, I can't figure out, what can be the problem. What I am doing wrong?
where doesn't expect a function inside ( todo=> ), but rather just a boolean thing. So, to make your code work, write something like from(TodoDb.todos)(todo => where(todo.userid === userid) select.
BTW, I suggest to be immediately cautious when seeing a code fragment like (todo => where (todo => (double "todo" definition).

Just learning how to write conditional tests using JS in Cypress. Write sample test as per Cypress.io
Test I trying to run:
describe ('sample tests', () => {
it('conditional test', () => {
cy.visit('https://example.cypress.io/commands/actions');
if (cy.get('input[placeholder*="Email"]')) => {
cy.type('email-1#mail.com')
} else {
cy.visit('https://www.google.com/')
}
})
})
Displayed error:
Error: Webpack Compilation Error

Module build failed (from C:/Users/userName/AppData/Local/Cypress/Cache/12.3.0/Cypress/resources/app/node_modules/babel-loader/lib/index.js):

What I tried:
I moved "=>" in different location but Cypress display that "No tests found".
Expected behavior:
Cypress must run test without error, using condition if-else.
Understanding the use of "=>" is essential here and it has nothing to do with cypress.
The "=>" belongs to Javascript arrow functions
This is used to introduce shorter functions.
Now let's understand the then() method, reading this document
With the above, you should be able to understand how to use these principles correctly.
More to note:
If an element doesn't exist conditionally, we cannot use cy.get for that element (will trigger No Such Element Exception). Use
cy.get("body).then($body => {
//cy.get("body") returns the dom element which we can capture
with "then"
//Check if element exists
if($body.find("input[placeholder*=\"Email\"]").length > 0){
cy.get("input[placeholder*=\"Email\"]").type("email-1#mail.com");
}
else{
cy.visit('https://www.google.com/')
}
})
To learn more on cypress if conditions read the Cypress Documentations
Hope this helps!
As far as I understand you, the purpose in your given example is to verify if the element (email field) exists and if so, type there a value. In this case you'd better use conditional testing the following way and verify if the field is visible:
const emailField = 'input[placeholder*="Email"]';
cy.get('body').then(($email) => {
if ($email(emailField).is(':visible')) {
cy.type('email-1#mail.com')
}
else {
// Anything to do here
}
});
Or you can just check that element exist (if it's hidden for any reason):
const emailField = 'input[placeholder*="Email"]';
cy.get('body').then(($parent) => {
if ($parent.find(emailField).length > 0) {
cy.type('email-1#mail.com')
}
else {
// Anything to do here
}
});
Instead of cy.get('body').then... you can use any DOM element which is higher in the hierarchy than your desired element.
I want to edit a message, but it's only updated when i changed this message _id. Can someone provide me how to do it, here is my code:
const onSend = useCallback((messagesToSend = []) => {
if(editMessage != null){
setEditMessage()
const m = messagesToSend[0]
const newMessages = [...messages]
const index = newMessages.findIndex(mes => mes._id === editMessage._id);
console.log('index: ', index)
if(index > -1){
newMessages[index].text = m.text // => ***i only edit the text***
// newMessages[index]._id = uuid.v4() => ***this working if changed _id***
console.log('newMessages', newMessages[index]) // => ***new message changed it's text but the bubble not change when re-render***
LayoutAnimation.configureNext(LayoutAnimation.Presets.easeInEaseOut)
setMessage(newMessages)
}
}else{
setReplyMessage()
appendMessage(messagesToSend)
}
})
It looks like you're using useCallback without a dependency array. This means that any dependencies that you rely on will be memoized and won't update when you run the function.
You should add messages, editMessage, and maybe setMessage and appendMessage, to the dependency array. Like so:
const onSend = useCallback(
(messageToSend = []) => etc,
[messages, editMessage, setMessage, appendMessage]);
That's the first thing I would try
ok i found problem, in MessageText the function componentShouldUpdate need modify a bit
I have a controller class and inside a method of the controller class, I have List Defined as below.
List<TrackedStoreProductsViewModel> currTrackProds = _context.Tracked_Products.Select(p => new TrackedStoreProductsViewModel()
{
TrackedProducts = p,
currentPrice = _context.Store_Products.Where(x => trackedId.Contains(x.product_id)).FirstOrDefault(s => s.product_id == p.product_id).Product_Price_History.OrderByDescending(pr => pr.price_timestamp).Select(pr => pr.price).FirstOrDefault(),
userEmailId = _context.User_Accounts.FirstOrDefault(u => u.account_number == p.account_number).email_id,
userFirstName = _context.User_Info.FirstOrDefault(u => u.account_number == p.account_number).first_name
}
).ToList();
Here I am getting the following exception error
Here the exception error is 'Unknown column 't.Store_Productsproduct_id' in 'field list'.
I checked all the models related to this, set up a breakup point stepped in still couldn't find where it is defined that way? Can someone suggest me an approach I can possibly follow to fix this issue?
I am trying to create a LinkedHashMap and populate it with a DateTime as the key and a List as the value in my flutter app. I keep running into problems with creating this.
Here is what I am trying right now without success:
List<dynamic> _getEventsForDay(DateTime day) {
for (int i = 0; i < eventDoc.length; i++ ) {
if (day.year == eventDate.year && day.day == eventDate.day && day.month == eventDate.month) {
List<dynamic> eventList = [];
eventList.add(eventDoc[i].agencyId);
eventList.add(eventDoc[i].agentId);
eventList.add(eventDoc[i].eventDate);
eventList.add(eventDoc[i].eventDescription);
eventList.add(eventDoc[i].eventDuration);
eventList.add(eventDoc[i].eventName);
eventList.add(eventDoc[i].eventStartTime);
return kEvents.putIfAbsent(eventDateUTC, () => eventList);
}
}
}
Everything is working except the last line and the putIfAbsent call. The eventDateUTC and the eventList both have values.
I am getting this error when I try to execute the
return kEvents.putIfAbsent(eventDateUTC, () => eventList);
line. When this line executes I get this error:
The method 'putIfAbsent' was called on null.
Receiver: null
Tried calling: putIfAbsent(Instance of 'DateTime', Closure: () => List<dynamic>)
kEvents is declared like this:
LinkedHashMap<DateTime, List> kEvents;
I am sure I am missing something small but I don't have enough experience with flutter to know what it is. Please help if you can.
I am trying to mock my repository's Get() method to return an object in order to fake an update on that object, but my setup is not working:
Here is my Test:
[Test]
public void TestUploadDealSummaryReportUploadedExistingUpdatesSuccessfully()
{
var dealSummary = new DealSummary {FileName = "Test"};
_mockRepository.Setup(r => r.Get(x => x.FileName == dealSummary.FileName))
.Returns(new DealSummary {FileName = "Test"}); //not working for some reason...
var reportUploader = new ReportUploader(_mockUnitOfWork.Object, _mockRepository.Object);
reportUploader.UploadDealSummaryReport(dealSummary, "", "");
_mockRepository.Verify(r => r.Update(dealSummary));
_mockUnitOfWork.Verify(uow => uow.Save());
}
Here is the method that is being tested:
public void UploadDealSummaryReport(DealSummary dealSummary, string uploadedBy, string comments)
{
dealSummary.UploadedBy = uploadedBy;
dealSummary.Comments = comments;
// method should be mocked to return a deal summary but returns null
var existingDealSummary = _repository.Get(x => x.FileName == dealSummary.FileName);
if (existingDealSummary == null)
_repository.Insert(dealSummary);
else
_repository.Update(dealSummary);
_unitOfWork.Save();
}
And here is the error that I get when I run my unit test:
Moq.MockException :
Expected invocation on the mock at least once, but was never performed: r => r.Update(.dealSummary)
No setups configured.
Performed invocations:
IRepository1.Get(x => (x.FileName == value(FRSDashboard.Lib.Concrete.ReportUploader+<>c__DisplayClass0).dealSummary.FileName))
IRepository1.Insert(FRSDashboard.Data.Entities.DealSummary)
at Moq.Mock.ThrowVerifyException(MethodCall expected, IEnumerable1 setups, IEnumerable1 actualCalls, Expression expression, Times times, Int32 callCount)
at Moq.Mock.VerifyCalls(Interceptor targetInterceptor, MethodCall expected, Expression expression, Times times)

at Moq.Mock1.Verify(Expression`1 expression)
at FRSDashboard.Test.FRSDashboard.Lib.ReportUploaderTest.TestUploadDealSummaryReportUploadedExistingUpdatesSuccessfully
Through debugging I have found that the x => x.FileName is returning null, but even if i compare it to null I still get a null instead of the Deal Summary I want returned. Any ideas?
I'm guessing your setup isn't matching the call you make because they're two different anonymous lambdas. You may needs something like
_mockRepository.Setup(r => r.Get(It.IsAny<**whatever your get lambda is defined as**>()).Returns(new DealSummary {FileName = "Test"});
You could verify by setting a breakpoint in the Get() method of your repository and seeing if it is hit. It shouldn't be.
