QUESTION
I'm learning about reactJS and for the database I'm using firebase realtime Database.. everything works. but there is one problem..
i have Firebase url like this
...ANSWER
Answered 2021-Jun-15 at 03:22The correct URL to get just that specific key is:
https://my-app-name-rtdb.asia-southeast1.firebasedatabase.app/data/-Mc8l24sBroFw8JoA32e.json
So the .json
is last, and before that you have the entire path to the data that you want to retrieve.
QUESTION
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:

QUESTION
I ran into a problem where I am assigning a value (via a dynamic variable) to a property of an object inside of an array. When the variable changes, the value doesn't update. Why doesn't it update, and is there another way I can implement this so it does update?
...ANSWER
Answered 2021-Jun-11 at 00:51You are just updating this.name
. You also have to update people
because name: this.name
is not reference.
QUESTION
I'm trying to choose the appropriate authentication flow for my application. I have a portal that users create accounts/login to. When they login for the first time, I want to present them with a "Terms & Conditions" form that requires a valid signature. I want to save the signed form in our database (and link to it from our Admin panel).
I don't necessarily want users to have to create a DocuSign account to sign with. In this previous question: Embedded signers from my application shouldn’t need to login @larry-k says:
If your application makes users (who will become signers) login to the app, that is a form of authentication. You can also turn on authentication options from DocuSign. Eg include KBA (Knowledge Based Authentication) in the signing request.
Here he alludes to making my App Users into Signers, but I'm not sure how this works. I don't want to use Knowledge Based Authentication, I'm more envisioning a SSO process to create a DocuSign User based on the App User information of the user logging in.
The same article suggests PowerForm as a possible solution. What happens after the user signs the form? How can I obtain the signed copies? I gather you cannot mix/match PowerForms with API integrations? I don't want to have to require an admin to login to DocuSign to collect signed forms.
...ANSWER
Answered 2021-Jun-10 at 23:00Q: What happens after the user signs the form?
A: just like any other envelope signed with Docusign, it is stored in the DocuSign cloud for the account that created the PowerForm.
A: How can I obtain the signed copies?
Q: You can download them using the eSignature REST API. You can either do this periodically (polling, not recommend) or get webhook notifications using Connect and get the signed PDF this way.
Q: I gather you cannot mix/match PowerForms with API integrations?
A: You can do that! You can have a PowerForm and you can also have separate API integration that downloads the PowerForm signed docs into your website.

QUESTION
Working Stackblitz:
I implemented 2 calendars in html, for filtering the data between 2 dates. When i filter data for the first time, i will select both calendar dates and the data is filtering. Now we have both the inputs for calendar given right. Now my issue lies here. When i change the first calendar date. the second calendar remains the same with previously assigned date as we filtered previously. and there is no change in the filtering of data until we give inputs to both calendars again. I want the second calendar value to be cleared on changing the first calendar. And also clear the first calendar input when the second calendar is changed. Please help me achieve this.
can we trigger the output based on either of the input values ? as of now it's not showing. example: i have 2 records in grid: with dates : 07/12/2020 and 15/12/2020 Initially if i filter from dec 1st 2020 to dec 31st 2020. It's showing both records. Now, again if i set 15/12/2020 in first calendar without changing second. There is no change in the table. i should enter second also. Can we fix it ??

Answered 2021-Jan-04 at 12:04You are not updating the list on the change of the first Date input. Update the list onChange of the first Date if the second Date already been selected. Change your code as below.

Answered 2020-Dec-31 at 17:41Make the following changes:
- Use another array called
display
that will be used to show the fltered out elements. - Each time the second date changes we reassign a new reference of the original array to
display
, else every time you filter out the original contents are lost. - Use this array to display the elements on the template.
