+## 5.9 Creating Our Production Database with migrate
+
+If use FT `functional_tests.py` to verify, will return an error `no such table: lists_item`
+
+Why? Because Django creates test database for unit tests, this database cannot be used by FT.
+
+Migrate the database using `python manage.py migrate`
+
+`functional_tests.py` Test Result:
+
+```
+AssertionError: '2: Use peacock feathers to make a fly' not found in ['1: Buy peacock feathers', '1: Use peacock feathers to make a fly']
+```
+
+* Problem: need to get list numbering right.
+* Solution: using Django template tag, `forloop.counter` in template `home.html`
+
+```html
+        <table id="id_list_table">
+            {% for item in items %}
+                <tr><td>{{ forloop.counter }}: {{ item.text }}</td></tr>
+            {% endfor %}
+        </table>
+```
+
+* Remaining problem: database are polluted by items from previous FT round.
+* ANS: Find a automated way of clear database after each FT
+
+```
+rm db.sqlite3
+python manage.py migrate --noinput
 ```
