QUESTION
I'm trying to tie a comment to the ticket. To do that, I have created a one to many relationship between Ticket to comment. However, I get an error message stating that.
SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Commenents_Tickets_Ticket_Id". The conflict occurred in database "NewTracker", table "dbo.Tickets", column 'Ticket_Id'.
I guess it's because I do not get my ticket_id when I make a comment. To try to solve this task, I have included ticket_Id which you can see in the view. (asp-route-Id="@Model.Ticket_Id).
In my view I am already inside my ticket where I want to make a comment as you can see in my url I have an Id /Ticket/Info/32
. I therefore thought it was possible to use asp-route-Id="@Model.Ticket_Idto be able to link to the ticket id?

QUESTION
I am trying to create a small pricing calculator. I am passing variables from id elements(complex,subject,number_quiz) to formula to calculate and output results to id variable total.
I after passing variables to the formula, it's not calculating and not displaying any results.
...ANSWER
Answered 2021-Jun-14 at 05:55First, I believe you mean var total = (com + subject) * n_q;
rather than var total = (com + subject)n_q;
.
Second, all if
clauses run the same code, so you can remove all the if
statements and leave the code as.
Third, you need to change getElementsById
to getElementById
.
QUESTION
Hi I am developing a runtime using Substrate-FRAME and I would like to know how can I write a system test for my runtime?
The main purpose of writing a system test is to ensure that the final build is fulfilling all of the required specifications and also to ensure nothing is compromised on a runtime upgrade. The idea for me is something similar to point no. 2 mentioned in this thread.
Any documentation regarding this type of tests would be greatly helpful.
Update:
I ended up using py-substrate-interface
to make test scenarios. Now I can automatically deploy nodes to form a network (thanks to Python) and run my custom system test scenarios. Very useful tool for developing runtimes in Substrate.
ANSWER
Answered 2021-Apr-14 at 16:18There is an overview here on the DevHub
And there are examples throughout substrate that include tests.rs
and mock.rs
files to use as reference.
If you have not already, checkout the create a pallet tutorial and the recipes all have some tasty examples to look at for these as well.

I'm implementing a validator to check which lines have the same name.
I want to display an error message saying: "This line is duplicated" below the input box.
Now I'm customizing the FormArray validation so that it shows the error message line by line but don't know what to do next.
In app.component.html file:
...ANSWER
Answered 2021-Jun-11 at 07:17It sounds like what you are trying to achieve is:
- Watch each
FormControl
(nested in aFormGroup
) to see whether it's value is the same as the value of any otherFormControl
(nested in aFormGroup
) in a givenFormArray
At a high level you then have two things you need to achieve:
- Get the value of an individual
FormControl
and compare it to a list of all of the other values (i.e. as you already have done in yourhasDuplicate
validator function) - Assign an error to the individual
FormGroup
s which contain theFormControl
s which are duplicate
The problem with creating a validator that will sit on the FormArray
is that the error you return will be assigned to the FormArray
itself and not the individual FormGroup
s. For example, if hasDuplicate()
returns an error , you will have this resulting form structure:
