Step 11: Item Form Pathway
There is a form in the template for creating items. There is a method in the CreateItem handler for handling HTTP POST, and creating an item.
I'll need to GET an Item form, making sure it has the list key. Again, CreateItem.get, unchanged:
class CreateItem(webapp.RequestHandler):
def get(self, list_key):
template_values = {
'item_form': 1,
'list_key': list_key }
self.response.out.write(render(template_values))
... and its matching template section:
{% if item_form %} {% ifequal list.key list_key %} <a name="form"></a> <form action="/create_item/" method="post"> <span style="padding-left:15px"> <textarea style="background:#eeee00" name="name" rows=1 cols=33> </textarea><br> </span> <span style="padding-left:15px"> <input type="Submit" name="button" value="Create item"> </span> <span style="padding-left:130px"> <a href="/">cancel</a> </span> <br> <input type="hidden" name="list_key" value="{{ list_key }}"> </form> {% else %} <br> <span style="padding-left:15px"> <a href="/item_form/{{ list.key }}/#form"> Create an item </a> </span> <br><br> {% endifequal %} {% else %}
We'll instantiate Items in the CreateItem.post handler:
def post(self):
item = Item()
item.list_key = self.request.get('list_key')
item.name = self.request.get('name')
item.put()
self.redirect("/")
