How can I access to last DB index?
For example, in my DB I create records with automatically generated names, like news-post1, news-post2, etc. To create name for new record, I need to access latest DB index.
In my case, I need to edit names of images like above. I already know how to access file extension, but not index of DB
def generate_image_name(obj, file_data):
img_extension = path.splitext(file_data)[1]
img_name = "news-img"+<?db.Index?>+img_extension
I find what i exactly what i searching for. For exmaple, at the moment i have 2 news records.
>>> News.query.all()[-1]
<News 2>
>>> News.query.all()[-1].id
2
