angular - Dynamically setting class name using ngClass -


i looping through list , displaying buttons.

within loop have job.hasjob. if set 1 add class button. name of class should job-block- plus value of job.hasjobdetails.statuscolour

for example, if job.hasjobdetails.statuscolour red class name job-block-red.

if hard code in class works:

<button ion-button color="dark" [ngclass]="{ 'job-block-red' : job.hasjob == 1}" (click)="changestatus(job.statuses)" outline>{{ job.jobname }}</button>

but if try error:

<button ion-button color="dark" [ngclass]="{ 'job-block-' + job.hasjobdetails.statuscolour : job.hasjob == 1}" (click)="changestatus(job.statuses)" outline>{{ job.jobname }}</button>

parser error: missing expected : @ column 16 in [{ 'job-block-' + job.hasjobdetails.statuscolour : job.hasjob == 1}] in bedjobspage@62:39 ("

i don't think can use object notation ngclass dynamic property names. try instead:

[ngclass]="job.hasjob == 1 ? 'job-block-' + job.hasjobdetails.statuscolour ? null"

or build class object in typescript:

getjobclasses(job) {    return {        ['job-block-' + job.hasjobdetails.statuscolour] : job.hasjob == 1    } }  [ngclass]='getjobclasses(job)'

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
