Question

I am following a google app engine exercise and having trouble rendering a jinja template properly.

The following code does what I expect it to do (it allows me to render a template with values from my GQL query:

def get(self):
    blogpost = db.GqlQuery("SELECT * FROM BlogPosts ORDER BY created ASC")
    self.render('blog.html',blogpost=blogpost)

That code renders my blog.html template with when I use tags like {{post.subject}}

This code does not let me render a template:

def get(self):
    path = self.request.path[1:]
    post = db.GqlQuery("SELECT * FROM BlogPosts WHERE ID = " + str(path))
    self.render('permalink.html',post=post)

Answer 1

i believe you can’t query by ID this way. The id is part of the entity key so:

SELECT * FROM YourModel where __key__ = KEY('YourModel', <numeric_id>)

this should give you the desired result.
