signalr-chat's Issues

delete message

hi
delete message is not developed

.Net Core version?

no single chatroom

no single chatroom

SQL

can i run the update-database also in a way it creates the database in a SQL Server instead of the SQL EXpress

One small suggestion, ie. improvement.

In index.cshtml on line 62 if you change <div class="left-side"> to

<div class="left-side" data-bind="if: !$data.isMine()">

then the sender's avatar won't be shown on his form, while others will still see it. It is really not needed for sender to see his own avatars all the time.

In this way you save the space, which is always a good thing. It also looks better in my opinion.

Deployment

So I killed Facebook, I wanted to try this as an alternative to communicate with my wife. It runs fine in the environment, but when I publish to IIS, it will start but when it tries to log in, it crashes with no data. Any help is appreciated. I switched to development mode but I get the same message :

Error.
An error occurred while processing your request.
Development Mode
Swapping to the Development environment displays detailed information about the error that occurred.

The Development environment shouldn't be enabled for deployed applications. It can result in displaying sensitive information from exceptions to end users. For local debugging, enable the Development environment by setting the ASPNETCORE_ENVIRONMENT environment variable to Development and restarting the app.

Problems with Getting Started

Hi! ;)

I've got some problems with the last command of Getting Started session. When I run update-database the return is:

Can you help me?

Where can i see the web demo?
can we private message others by clicking on their name instead of typing in code /pm name of person. ?

Private messages not saved

Hi,

I'm not sure if this is by design but private messages are not saved to database.

Why is so?

Is your 'project' designed to basically work within Visual Studio?

Is your 'project' designed to basically work within Visual Studio?
If not, and can be 'deployed' externally, could you provide the steps necessary?

Thanks

update

Hallo,

I hope you can help me out with the following.
I changed the code so we can change the roomnames afterwards.
It works and we also post back a procedure with signalr to update all users with the new info.

But I do not get it working to update the content at the clients without refreshing the page.

I tried this
var temp;
ko.utils.arrayForEach(self.TweetDeckRooms(), function (room) {
if (room.id() == id)
temp = room;
});
temp.Name = Name;

and this:

var recordToupdate = this.TweetDeckRooms.FirstOrDefault(x => x.TweetDeckRoom.id == id);
if (recordToupdate != null) {
recordToupdate.Name = room.Name;

       }

But both do not work
