QUESTION
I'm fairly sure I know the problem. I think its because of the child component rendering before its props are ready. After looking at many tutorials and docs I just can't figure out what I'm doing wrong.
I am using hooks and useEffect to get Data from firestore when the page opens. after that, I want to pass the data to a child component "Table.js" to be displayed. If I have the table in the parent component it works fine, but as soon as I move the table to its own component i get an error saying forms.map is not a function `TypeError: forms.map is not a function
Here is my code for the parent component MainScreen.js

...ANSWER
Answered 2019-Feb-18 at 01:44Sounds like Model.Fields
property still contain null when db.NewForms.Find()
is executed to assign the model you want to return into view, indicating that EF doesn't create dependent collection yet. As far as I know you should add collection instance definition inside parameterless constructor of entity class:

Is there any static event that is triggered when a handle for a Winforms control is created or when it is loaded for the first time?

...ANSWER
Answered 2018-Nov-28 at 14:14I was inspired by this answer and used SetWinEventHook
API to create a new WinForm monitor. Basically, it monitors the EVENT_OBJECT_CREATE
event and fires an event whenever a new window is found.
The usage is very simple. You create a new instance and then attach a handler to the NewFormCreated
event. Here is an example:
QUESTION
I have created a web application. Where the form name is requested to input when the "new " button is clicked and then when the save button is clicked the name should be shown at that dialog box. I have created the relevant services but the name is not shown. Here are the code segments
NewForm.component.ts
...ANSWER
Answered 2018-Oct-19 at 03:16You have issue with persistent of value formName
. Your opted the service approach for communication among different component which is right however you are notifying the component instantly through the Observer. But the component (modal
) has not yet appeared.
If you save formName
through on modal
and open the another modal
since the notification is already been sent and this this modal which is new Subscriber
will not be aware what had happened in the past.
So fix this issue you can retain the last saved value in the service which you are already performing.
So just replace your Subject
by BehaviorSubject
.The BehaviorSubject
has the characteristic that it stores the current
value. This means that you can always directly get the last emitted value from the BehaviorSubject
.
QUESTION
I am trying to output two same forms and save them to database with different prefix. I used this post https://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ as an example. However I get validation error that management form is being tampered with. Could you please kindly advise how to solve it? Thank you.
Also is it possible to filter database by the prefix in this case if i want to retrieve the data later for analysis.
