I'm just getting started with cloud endpoints by following the tutorial from
here.
Even when i copy paste the code exactly, I'm unable to look at the custom endpoin methods. When I run the project and type
http://localhost:8080/_ah/api/explorer
I get redirected to a blank api-explorer page. Here are the logs from the App Engine Launcher

The app.yaml and python files are exactly as described in the tutorial.
Can someone please tell me what exactly is going on and how to fix it.

I created a Flasgger/Swagger App in Spyder and got returned:

When trying to visit this app in my Google Chrome browser via http://127.0.0.1:5000/apidocs/ I got back this error:

What do I have to change here?

I Have faced this same error for the last two months eventually I Solved at the end.
Error:
When a user token is become expired we will be getting 401 status code with unauthorized message, when this happens the next API is also getting interrupted it returns 405 Method Not Allowed as an error.
Solution :
There was a bug issue in Django version 2.1 you have to upgrade your django version to 2.2.
After that check this error it will not raise.
HTTP_405_METHOD_NOT_ALLOWED
The status code 405 represents that you are requesting in a method that is not allowed.
Based on your code, You are defining Token API to be accessible by post method.
look at this log:
[07/Dec/2018 11:48:09] "POST /account/token/ HTTP/1.1" 200 517
in this you are sending clear POST request which will be ok. but look at the provided log for failed cases:
[07/Dec/2018 11:24:30] "{"email":"email#hidden.com","password":"hidden_password"}POST /v1/account/token/ HTTP/1.1" 405 66
1- For some reason in your UI, you are sending a request with method {"email":"email#hidden.com","password":"hidden_password"}POST!!!!.
2- and you are sending request to /v1/account/token/ API endpoint which is not registered in your urls at all (based on what info you gave us)
I'm making a blog using Google App Engine, which for now just allows me to post entries and see them listed out. I was following the Web Development course by Steve Huffman on Udacity where he showed a simple caching technique to decrease the database queries. Here's my code (which he instructed):
CACHE = {}
def top_entries():
key = 'top'
# logging.error(CACHE)
if key in CACHE:
entries = CACHE[key]
else:
logging.error("DB QUERY")
entries = db.GqlQuery('select * from Entries order by created desc limit 10')
entries = list(entries)
CACHE[key] = entries
return entries
class MainPage(webapp2.RequestHandler):
def get(self):
entries = top_entries()
self.response.write(render_str('mainpage.html', entries=entries))
mainpage.html is just the main page that lists the 10 most recent entries.
Basically, CACHE is a dictionary that stores a key that identifies a particular database query (in this case, listing out the top 10 entries) and on further calls to the same query, the application simply looks in that dictionary without making a database call.
What SHOULD happen is this:
I load the page for the first time and DB QUERY is printed on my console since it's a database call. The result of the query is stored in CACHE.
I reload and DB QUERY isn't printed since the cache has the key.
The above DOES happen but only if I have a fresh new tab to work on. If I already have a tab where I was working on this app, and I shut down the server, reboot it and then try reloading the page again, the above doesn't work. What happens is that step 1 happens twice and then step 2. It seems like the key isn't stored in the CACHE the first time I reload the page, but on the second time.
Here's the console log if the above paragraph is hard to follow:
The first time I boot the server and start working on a fresh tab:

DB QUERY gets printed out twice instead of once. I can't think of any reason why it would behave this way. (Maybe because of my browser cookies?)
You are caching at instance level and you can have number of instances or an instance can be recycled (shut down) and a new one instantiated on a request.
Try to use Memcache if you want to share cache between instances:
https://cloud.google.com/appengine/docs/python/memcache/
You can combine both approaches (instance cache + memcache)

I am new to Django and web development. I don't know how to describe my problem. No idea what info to provide. I need some hints to debug.
I have two virtual machines. On one machine, I built my Django project, installed the package, and run it on apache2.
On the other machine, I run python manage.py runserver 0.0.0.0:8000 from the source codes.
Browsing the same page, the web page on machine 1 is OK.
But nearly every form disappeared on machine 2.
Checked the source of the two pages, they are the same.
The output on machine 2 seems OK too:

UPDATE
Solved this problem. see the error above. It failed to import some js files, and then the page not shown.
If they're each using separate copies of the database server, it may be that database migrations have not been run yet on machine 2.
I am new to Django and this question may seem to be easy. In the terminal where "python manage.py runserver" is executed, the following logs periodically appear.
[30/Sep/2015 02:36:02] "GET /messages/check/?_=1443574208652 HTTP/1.1" 200 1

Questions are:
Why does the logs periodically appear? I guess there is a background task running.But Celery package is not used here.
How to configure the logs, for example, displaying one more logs such as:
/followers/check/?_=9896886900907 HTTP/1.1
What do "?_" and the long string of numbers stand for? I can understand the "?first_feed=13" means the querying parameter in Django request object.
GET /notifications/check/?_=1443574208656
When Django is run in development mode (with runserver) it prints a line for all HTTP requests received to the console.
All of them are coming from the outside, browsers, feed readers...
The parameters you are wondering about are GET query parameters. The ? is the delimiter so, _ is the key of the argument.
In development mode the logging is defined by default. If you want to have logging on your production system or more logging, read https://docs.djangoproject.com/en/1.8/topics/logging/ .
