Hi guys
I have a problem with tutorial with Delete article button.
When i click Delete article button Alert pop up appears BUT when i click NO, the article gets deleted anyway!
I’ve double checked my code
Homepage:
def delete_article(self, article, **event_args):
# Delete the article
anvil.server.call(‘delete_article’, article)
self.refresh_articles()
ArticleView
def delete_article_button_click(self, **event_args):
“”“This method is called when the button is clicked”""
confirm(“Are you sure you want to delete {}?”.format(self.item[‘title’]))
self.parent.raise_event(‘x-delete-article’, article=self.item)
ArticleServerModule
@anvil.server.callable
def delete_article(article):
if verify_user_permission(article):
# Delete the article
article.delete()
else:
# Raise an exception if the article doesn’t exist in the Data Table
# or the user doesn’t own the article being deleted
raise Exception(“Article does not exist or does not belong to this user”)

Your answer is further up that thread. You call confirm, but do not use it in an if statement, so your event is raised no matter what.
