Question

What I want to do is build some mini cms which hold pages with a uri.

The last route in my urls.py points to a function in my views.py, which checks in the datastore if there’s a page available with the same uri of the current request, and if so show the page.

I have a model:

class Page(db.Model):    title = db.StringProperty(required=True)    uri = db.TextProperty(required=True)    created = db.DateTimeProperty(auto_now_add=True)    modified = db.DateTimeProperty(auto_now=True)    content = db.TextProperty()  

In my view:

def show(request):    page = db.GqlQuery('SELECT * FROM Page WHERE uri=:uri', uri=request.path).get()    if page is None:      return http.HttpResponseNotFound()    else:      return respond(request, 'pages_show', {'content': request.path})  

And I’ve added an entity with ‘/work’ as uri to the datastore.

Even when request.path is exactly ‘/work’, the query does not return a match.

Thanks for any advice you can give me!

And yes, i’m a python noob, App Engine is perfect to finally learn the language.

Answer 1

I’ve found the solution!

The problem lies in the model.

App engines datastore does not index a TextProperty. Using that type was wrong from the beginning, so i changed it to StringProperty, which does get indexed, and thus which datastore allows us to use in a WHERE clause.

Example of working model:

   class Page(db.Model):        title = db.StringProperty(required=True)        // string property now       uri = db.StringProperty(required=True)        created = db.DateTimeProperty(auto_now_add=True)        modified = db.DateTimeProperty(auto_now=True)        content = db.TextProperty()
