I am a beginner to Django.
I want to create a form that allow user to store their data to the database, but I face to an issue.
If I add data through Django admin, the data will shown correctly. But if I add data through my form. Data will store into database successfully but they don't shown in my Django admin.
Note: The Django version I used is 1.11.2
The is my Django admin page. There are 8 data in the database but just show the one I added by the Django admin.
