Important classes or definition

Table defined in the db as

CREATE TABLE "chatapp_chatinfo" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, 
"question" varchar(200) NOT NULL, "answer" varchar(2000) NOT NULL,
"category" varchar(100) NOT NULL)

Model defined in the project

class ChatInfo(models.Model):
    question = models.CharField(max_length=200)
    answer = models.CharField(max_length=2000)
    category = models.CharField(max_length=100)

    # Returns answer for the particular model object
    def __str__(self):
        return self.answer

Python code for accessing data from db. The above defined str function directly outputs the required field.

response = str(ChatInfo.objects.get(question=userinput))
