I have a 'job' component that will load a given job from Mongo based on an
id retrieved from the router.
I also have a 'job-form' component that is a sibling component and I want
to initialise the input fields with the current job data. I'm currently
retrieving the job data from an observable (rxjs BehaviourSubject) in a
service but since the data from mongo is asynchronous the data I try to
initialise the form with is undefined when the form is created So I get:
TypeError: Cannot read property 'name' of null
I tried using:* job?.name* but then I get:
The '?.' operator cannot be used in the assignment at column 11 in
[job?.name=$event]
I also tried using the async pipe but I get:
Cannot have a pipe in an action expression at column 12 in [job.name |
async=$event]
So whats the best approach here?
Also, if i've already loaded my job in my 'job' component can I not just
get that variable from my 'job form' component without having to call it up
from Mongo for a second time? Currently I have to call my service function
from my job form component as well to get the subscription to work, e.g.:
getJobById(id) {
this.subscription = this.subscribe('jobs', () => {
this.job$.next(Jobs.findOne({"_id":id}));
}, true);
}
