Angular Template Parsing Errors with Django REST framework: Fixing the "<" symbol

Recently, I've been working on developing a DRF API integrated with an Angular front end for one of my ongoing projects. Specifically, I have created serializers for User and Device. However, during the process, I encountered an error related to StaticInjectorError(AppModule -> DevicePostService) after removing certain components from the HTML layout.

As someone relatively new to Angular, it appears that the issue stems from my devicepostservice not being properly served to the web page for some unknown reason.

Error displayed in console:

[Error] Error: Template parse errors:
Unexpected character "<" ("
  <div class="col-sm-4">
    <button (click)="login()" class="btn btn-primary">Log In</button
  [ERROR ->]</div>

Answer №1

It appears that there is a minor syntax error in your template code

<button (click)="login()" class="btn btn-primary">Log In</button

should actually be

<button (click)="login()" class="btn btn-primary">Log In</button>

(please take note of the final '>' character)
