Hi,

I've an external web client that needs to connect to my aspnetcore server. The problem is that authentication request cames with a plain text format instead of json. The result is an HTTP 415 error.

Is it possible to configure authentication aspboilerplate server to accept plain text format as well ?

Hi,

I'm running my app over Azure. Sometimes, I'm getting a server error popup message when connecting to a tenant or on first host connection. Looking at logs, I've remarked two exceptions that are fired very often (each time server starts at least). Here they are

Do you know how to fix this ?

Hi,

I would like my users to be able to add entities attributes themselves from UI. It's a common scenario for a professional application and I would appreciate your advice to start implementation.

Basicaly, the user should be able to go in some application settings, and add a property name, a property type and a target entity. As a result, when the user will open an entity (let's say a Product entity) then he will have new attributes displayed.

I have two main ideas in mind :

• SOLUTION 1 : create a specific entity, let's say AdditionalAttributes (to store property names and types). Then I will add a ICollection<AdditionalAttributes> to a set of existing entities (the ones I want users to be able to extend). I know how to do this in ASPNETZERO context from domain layer to presentation layer. Don't know if this will lead to performance issues or whatever bad.

• SOLUTION 2 : adding an XML property to each entities to extend. I don't have much experience on this approach and don't know how to implement this on UI side at least. See here : [https://stackoverflow.com/questions/30783224/dynamically-adding-a-property-to-an-entity-framework-object])

Do you have other solutions in mind ? What's your advice as ASPNETZERO experts ?

Hi,

My app is running on Azure for several month now. I've an Azure Standard subscription (S1) : CPU usage is about 2/3% and Memory usage arround 45%. When trying to chat to an other user, the message sent takes some seconds to be displayed in the chat list (4s to 10s sometimes) Also, when pressing Enter key, the chat message remains in the input field before being displayed in the chat list. In some cases, one message sent can be displayed twice (??)

This behavior is very frustrating when trying to chat with an other user.

Do you have an idea how to improve this ?

Hi,

My application is down since yesterday. Application is deployed in an Azure App Service since december 2017. I never had a problem with it ; everything was working well since yesterday.

Today, my customers can't connect to the app with error IIS 502.5.

Host is not able to start.

I have following error in azure log : Application 'MACHINE/WEBROOT/APPHOST/NAME-APP' with physical root 'D:\home\site\wwwroot' failed to start process with commandline 'D:\home\site\wwwroot\ELEVEN_SOFT.NAME.Web.Host.exe ', ErrorCode = '0x80004005 : e0434352.

And on latest application log, I found following exception ; this exception points out that a file is not found but it is present in file system (no change has been done) it also mentioned an error on startup.cs line 141 which is code line

await next();

I googled these errors and it could be link with a .NETCORE version issue on server... but I didn't change anything on Azure portal.

Can you please help me to solve this ?

Hi,

I would like to switch current metronic 5 theme (default) to demo 6 available here : [https://keenthemes.com/metronic/preview/?demo=demo6])

Do I need to recompile the entire theme to do it (I don't see the "tools" folder to do that like it is mentioned in metronic documentation) ? Or just by changing a setting ?

If I'm not wrong, the entire look & feel of current theme is located in folder : src\assets\metronic\dist\html\default\assets\demo\default\base with following files

scripts.bundle.js style.bundle.css

Do you confirm ?

Hi,

In my current project, my customer asked me to restrict access to an entity (let's call this entity "People") according to the user currently logged. The goal is to hide some people entities according to the user. A people entity can be visible for more than one user. Therefore, the relationship between people and user is a many-to-many.

I plan to :

• Add a collection of people to User entity OR
• Add a collection of people to OU entity

Then, I just need to adapt my app service query to retrieve a list of people that is visible for the current user.

Do you have any advice to do this in a better way ?

I had a look to dynamic filters but don't know if this could help as the relationship between people and user is a many-to-many.

Sometimes, I have following error on my website deployed on Azure (ASP.NET + ANGULAR) :

Do you already had this kind of errors ? Any idea on your side ?

Hi,

I don't understand how logo image are being managed when an email is sent from application (let's say a subscription email). See attached screenshot. If I browse directly to TenantCustomization/GetTenantLogo of my website, nothing is shown.

Is it a bug ? Or do I have to configure something else ?

Hi,

I'm getting an AbpExceptionFilter error with following query. This query allows to get users in OU.

//Find users in OU
                var query = (from u in UserManager.Users
                             join ou in _userOrganizationUnitRepository.GetAll()
                             on u.Id equals ou.UserId
                             select u).Distinct().WhereIf(
                        !input.Filter.IsNullOrWhiteSpace(),
                        u =>
                            u.Name.Contains(input.Filter) ||
                            u.Surname.Contains(input.Filter) ||
                            u.UserName.Contains(input.Filter) ||
                            u.EmailAddress.Contains(input.Filter)
                    );

                //Workarround to avaid abpdatafilterexception when counting query > Performance impact by calling ToListAsync !
                var count = (await query.ToListAsync()).Count;

As you can see, a distinct keywork is added to avoid duplicated users (as a user can be on multiple OU)

If I remove Distinct keyword from the query, I have no more exception.

Any idea how to avoid this exception ?
