Currently, I am in the process of building a web application with Google App Engine and Python. I have encountered an unusual issue that has left me stumped on how to resolve it and what might be causing it. The problem arises when I fill out a form and send the data for validation. If any fields are incomplete or missing, the server sends back the form with a prompt saying "FILL ALL THE FIELDS!"
This functionality works quite well.
My objective is to return the form with the "description" and "title" fields pre-filled with the user's previous input before submitting the form. This way, the user would only need to complete the unfilled fields without having to re-enter everything from scratch.
Here is the snippet of the code:
class SaleAnnCheck(BaseHandler):
# Python code implementation goes here
class Create(BaseHandler):
# More Python code implementation goes here
Upon form submission, the content undergoes checking through an HTTP post request to a specific URL managed by SaleAnnCheck.
The session accurately stores the Description and Title values (verified via the logs). However, if a field is left blank, the server redirects back to the form page through a GET request to a related URL.
The requests to this URL are handled by Create. Strangely, when attempting to render the HTML template of the form using jinja2 with the previously entered Description and Title values, the corresponding text areas remain empty. This discrepancy occurs despite verifying non-empty values earlier in SaleAnnCheck.
I am puzzled as to why this happens. Can anyone shed light on this peculiar issue? Thus far, I have been unable to find any insights or recommendations online.
