I'm a real newbie to Django, (following tutorial in openclassroom)
I have a django project called "blog", the code in the file "urls.py" of the main DjangoProject is this:
DjangoProject\urls.py
The code in blog\urls is this:
blog\urls.py
When I run the server, I get this:
Result
Help is very much appreciated !
on your project urls.py you should change this path('blog/') to this path('') as in your case you do not have configured the path ('/') on your project urls so the / is not found because the blog is linked to localhost:8000/blog url
The problem lies in your URL configurations. You are navigating to https://127.0.0.1:8000/, but this is not a URL you have defined. Your available URL paths are https://127.0.0.1:8000/admin/ and https://127.0.0.1:8000/blog/. Navigate to https://127.0.0.1:8000/blog/ and it should be working.
Or make the following change to your DjangoProject/urls.py:
path('', include ('blog.urls'))
Hope this helps.

So I have been trying to get used to Flash in python but I've come across a problem. I want that when http://localhost:5000/ is inserted in the browser a html page is displayed. I've tried multiple ways to do this like using the render_template() but that returns me a jinja2.exceptions.TemplateNotFound: index.html. I've also tried a simple return redirect() but that throws something saying the adress was not recognized or understood. When I tried using the url_for() it threw 404 - not found. I really have no idea how to fix this.
# htppserver.py
import flask
import threading
app = Flask(__name__, template_folder="Dashboard/website")
#app.route("/site", methods=["GET"])
#app.route("/", methods=["GET"])
def get_site():
return render_template("index.html")
x = threading.Thread(target=app.run)
x.start()
Currently my dir system looks something like this
main_folder # This is the working directory accordingly to os.getcwd()
├──cogs
│ └──httpserver.py # Source code is here
└──Dashboard
└website
├──...
├──index.html # This is the file I want to show
└──...
Thanks
put your html files in a folder called "templates" in the same directory as the python file that serves
I have two different urls:
1) /campaigns/, which lists available campaigns and 2)campaigns/add/ where there is a form to fill the details of a campaign to be created.
My django urls.py file looks like:
url(r'^campaigns/', views.campaigns, name='agency-campaigns'),
url(r'^campaigns/add/$', views.add_campaign, name='agency-add-campaign')
The problem is that whenever I browse the /campaigns/ url, it shows the correct template. But when I browse the /campaigns/add/ url, it still shows the /campaigns/ url template.
What can be wrong with this subdirectory?
Any ideas?
Thanks in advance!
That's because you don't have the end of string match ($) at the end of the regular expression:
url(r'^campaigns/$', views.campaigns, name='agency-campaigns'),
# HERE^
Or, you can also put the "agency-add-campaign" pattern before the "agency-campaigns":
url(r'^campaigns/add/$', views.add_campaign, name='agency-add-campaign'),
url(r'^campaigns/', views.campaigns, name='agency-campaigns')
I'm new to web.py, and use a lot of hardcoded url in my code for href in tag a,like
/loginor/?type=example.
The problem is,
when I set my application running under a certain path, not the root of a URL, like
http://example.com/appname/
The link will direct me to some place like
http://example.com/login
While the expected/wanted one is
http://example.com/appname/login
How do I handle this?
Make web.ctx.homepath available in your template globals, and output it before your paths.
From http://webpy.org/cookbook/ctx
homepath – The part of the path requested by the user which was
trimmed off the current app. That is homepath + path = the path
actually requested in HTTP by the user. E.g. /admin This seems to be
derived during startup from the environment variable REAL_SCRIPT_NAME.
It affects what web.url() will prepend to supplied urls. This in turn
affects where web.seeother() will go, which might interact badly with
your url rewriting scheme (e.g. mod_rewrite)
template_globals = {
'app_path': lambda p: web.ctx.homepath + p,
}
render = template.render(my_template_dir, globals=template_globals, base="mylayout")
Then you should be able to output app_path in your templates

So I have successfully deployed an app using webapp2/jinja2 and a Paste server, but am having trouble serving static stylesheets.
I have had luck accessing static files via this method, as well as implementing a StaticFileHandler I found with some google-fu:
import os
import mimetypes
import webapp2
import logging
class StaticFileHandler(webapp2.RequestHandler):
def get(self, path):
abs_path = os.path.abspath(os.path.join(self.app.config.get('webapp2_static.static_file_path', 'static'), path))
if os.path.isdir(abs_path) or abs_path.find(os.getcwd()) != 0:
self.response.set_status(403)
return
try:
f = open(abs_path, 'r')
self.response.headers.add_header('Content-Type', mimetypes.guess_type(abs_path)[0])
self.response.out.write(f.read())
f.close()
except:
self.response.set_status(404)
where my main app routing looks like:
app = webapp2.WSGIApplication([('/', HelloWorld),
(r'/display', DisplayHandler),
(r'/static/(.+)', StaticFileHandler)
], debug=True)
My css files are in a folder under the app root: /static/css/main.css
I can access the file via direct url, and even link it as a stylesheet, but the styles won't apply. Any ideas? Is there another way to serve stylesheets? Some way to implement an app.yaml similar to GAE?
you dont need a static file handler.
upload the app with the static file folder by adding this to your app.yaml
- url: /static/
static_dir: static
docs are here: https://developers.google.com/appengine/docs/python/config/appconfig#Static_Directory_Handlers
edit:
see answer below in comments
#Mnemon, hats off to you for solving my problem. I would upvote you but I'm not allowed to do that. You convinced me that if it's not the only webapp2 way without GAE, it's at least a way that will work.
But also I can contribute that your solution is now installable as "pip install webapp2_static", from pipi--- by an author who seems to be using his real name... you I'm sure. Other webapp2 docs that I found helpful are available here.
I'm implementing your code on a Linux desktop development server, using paste, which you also used:
def main():
from paste import httpserver
httpserver.serve(app, host='127.0.0.1', port='8080')
But with the code as you have it above (which appears to be utterly identical to that of webapp2_static.py file), I don't find that putting my css files in a folder named static in the app root works as you said.
For example, I have /home/user/proj/public_html/app/app.py, where the py file contains your code plus other "views" for my ultra-simple site. (I don't know how paste really works, so maybe for now the public_html is just in there for reference so that I don't become confused when I'm uploading stuff onto the production server.)
So if I put the css stylesheets into a folder named /static, then, if I put /static in as either a subdirectory of /app or of /public_html I find that neither location works; I must instead make it a subdirectory of /proj.
I wasn't expecting that, but the cure for me is to change the default 'static' in your app.configure.get(..., 'static') call, to 'public_html/app/static'. Then it works, with the /static folder inside /app.
Similarly using the pipi code with './app/static/ in place of the default 'static' doesn't work; I found that I need ./public_html/app/static instead (or maybe it was just /public_html/app/static or even public_html/app/static... I forgot... one of those worked).
I tested how your computation of abs_path works and have reworked it in the code below, in which I have junked your approach in favor of something more Djangoesque. To wit, in my one app py file I put at the top the following:
STATIC_DIR = os.sep + 'tostatic' + os.path.abspath(os.path.dirname(__file__)) + os.sep + 'static'
Then in the page to which I want to add css, my Home page in my case, I put a very readable:
<link href="{{STATIC_DIR}}/dist/css/bootstrap.min.css" rel="stylesheet" type="text/css">
For the "view" that generates my Home page I have (env is a jinja2 Environment object that takes a template loader as an argument):
class Home(webapp2.RequestHandler):
def get(self):
template = env.get_template('index.html')
template_values = {'STATIC_DIR': STATIC_DIR }
self.response.write(template.render(template_values))
And finally the URL routing is as in:
app = webapp2.WSGIApplication(
[
(r'/', Home),
(r'/tostatic/(.+)', StaticView),
], debug=True)
The view for the static file serving is now:
class StaticView(webapp2.RequestHandler):
def get(self, path):
path = os.sep + path
try:
f = open(path, 'r')
self.response.headers.add_header('Content-Type', mimetypes.guess_type(path)[0])
self.response.out.write(f.read())
f.close()
except Exception, e:
print 'Problem in StaticView:', e
self.response.set_status(404)
To finally close, the problem that I had with your approach is the one that I and other near noobs have with the departure of URLs from the legacy association with the file system. In your approach "static" is both a sub-directory and a string between slashes at the front of the URL that tells the interpreter which view (which webapp2.RequestHandler subclass) to run. You take the /static from the rest of the URL and then later hard-code it back on. And when it comes time to decide what to put in for href in the tag the HTML page coder has to remember that duplicity. With the {{STATIC_DIR}} template variable approach it's clear what to do. And it's easy to redefine the location of the static files--- only the STATIC_DIR declaration has to be changed.
I found that self.response.set_status(404) shows up in Firebug, but not Firefox. Evidently with webapp2 you must provide and serve your own HTTP status code pages.
self.response.headers.add_header('Content-Type', mimetypes.guess_type(abs_path)[0])
self.response.headers['Content-Type'] = mimetypes.guess_type(abs_path)[0]
I am trying to set up Google App Engine unit testing for my web application. I downloaded the file from here.
I followed the instructions in the readmen by copying the directory gaeunit into the directory with the rest of my apps and registering 'gaeunit' in settings.py. This didn't seem sufficient to actually get things going. I also stuck url('^test(.*)', include('gaeunit.urls')) into my urls.py file.
When I go to the url http://localhost:8000/test, I get the following error:
[Errno 2] No such file or directory: '../../gaeunit/test'
Any suggestions? I'm not sure what I've done wrong. Thanks!
You can copy url but in your urls.py include
(r'^test', include('gaeunit.urls')),
Also you will have to change test path in gaeunit.py
_LOCAL_DJANGO_TEST_DIR = 'test'
And in your main web test files under test folder include following line for django test setup
self.application = django.core.handlers.wsgi.WSGIHandler()
According to the instructions on the main page you should add the URL to app.yaml, not urls.py.
- url: /test.*
script: gaeunit.py
