python - Flask application on google app engine - Showing database object -

-

i'm trying make flask app on google app engine shows database entries on own page.

this bit of views.py code:

@app.route('/posts/<int:id>') def display_post(id):     post = post.filter('id =', id)     return render_template('display_post.html', post=post)

then display_posts.html

{% extends "base.html" %}  {% block content %} <ul>     <h1 id="">post</h1>     <li>         {{ posts.title }}<br />         {{ posts.content }}     </li> </ul> {% endblock %}

now when have post id 5700305828184064 , visit page should see title , content:

www.url.com/posts/5700305828184064

however traceback:

<type 'exceptions.attributeerror'>: type object 'post' has no attribute 'filter' traceback (most recent call last):   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/main.py", line 4, in <module>     run_wsgi_app(app)   file "/base/data/home/runtimes/python/python_lib/versions/1/google/appengine/ext/webapp/util.py", line 99, in run_wsgi_app     run_bare_wsgi_app(add_wsgi_middleware(application))   file "/base/data/home/runtimes/python/python_lib/versions/1/google/appengine/ext/webapp/util.py", line 117, in run_bare_wsgi_app     result = application(env, _start_response)   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/flask/app.py", line 874, in __call__     return self.wsgi_app(environ, start_response)   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/flask/app.py", line 864, in wsgi_app     response = self.make_response(self.handle_exception(e))   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/flask/app.py", line 861, in wsgi_app     rv = self.dispatch_request()   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/flask/app.py", line 696, in dispatch_request     return self.view_functions[rule.endpoint](**req.view_args)   file "/base/data/home/apps/s~smart-cove-95709/1.384741962561717132/blog/views.py", line 25, in display_post     post = post.filter('id =', id)

how can show title , content of entry given id?

you need create query object first, apply filter that.

q = post.all() post = q.filter("id =", id)

this first example in gae docs on queries.

also, template references name posts, you've passed in name post. change template appropriately.
