Currently working in Django, and I'm trying to set things up so that a form on one page calls a specific URL, for which the appropriate view is rendered. I'm having trouble with the regular expression that parses the URL, as it won't read the value '\?' as an escaped question mark, which is what I believe it should be doing. The following RE checks out on Pythex.
When the app submits the form, it calls the URL:
http://127.0.0.1:8000/map/?street=62+torrey+pines+cove&city=san+diego&state=CA&radius=50&drg=4
In my project level urls.py file, I have the following:
url(r'^map/', include('healthcare_search.urls', namespace="healthcare_search")),
This calls my app level urls.py file, where I have:
url(r'^\?street=(?P<street>[a-z0-9+]+)&city=(?P<city>[a-z+]+)&state=(?P<state>[a-z]{2})&radius=(?P<radius>[0-9]{1,3})&drg=(?P<drg>[0-9]{1,3})', views.map_hospitals, name = "map_hospitals"),
This just results in a 404 error, saying the URL doesn't match any of the patterns. I know that it's a RE problem, because I removed everything from the app level RE, and submitted just http://127.0.0.1:8000/map/ to see if it would call the right view, which it did successfully. Things seem to break apart on the '\?'. Any ideas what I'm doing wrong?
As a note, this is the first time I've written a regular expression, so my apologies if it is unclear or poorly written.
You don't want to get access to the variables that way. A better option is to get them from the request, since they'll be available in the request's dictionary of variables. In your view, you can get the value of street via request.GET.get('street', None), which will return the value if street is in the request or return None otherwise.

I have this url which returns the json data of my models but I don't know how to create a unit test for a url like this
path("list/", views.json_list, name="json_list"),
I'm not really sure what is being asked. A test like this
url = reverse('myapp:json_list')
response = client.get( url)
body = response.content.decode()
is going to fail if anything is wrong with the url definition. (Specifically, reverse will fail if the name doesn't exist, and for an url with arguments, if what you supply as kwargs isn't accepted by the url definition).
As for validating the response, we can't help without knowing a lot more about what is expected. Presumably, you will locate the start of some JSON text in body, feed it to json.loads, and make sure the data is as expected. But I don't think that's what is being asked.
I need one small help. I have one django application already with me and everything is working fine. Now requirement is without making change in existing functions we want to pass urls parameter as a query string
path('my-app/', include('myapp.urls', namespace='myapp')),
# I added this line because I want to use dcid as a querystring
url(r'^my-app/(?:(?P<dcid>\w+)/)',include('myapp.urls', namespace='myapp')),
and my function is already written like this
def orders_b2b_open_list_pageable(request):
We don't want to change in above functions but we want dcid in query string. How can we achieve that
I am doing this but when requesting like this
http://localhost:8002/my-app/1/orders/b2b/open/pageable/
I am getting following error
Thank You in advance
There's no need to parse it in your urls.py, that would change your function signiture.
You can handle it in your view, by pulling the querystring value from the request:
def orders_b2b_open_list_pageable(request):
dcid = request.GET.get('dcid', None)
...
(The title may be in error here, but I believe that the problem is related to escaping characters)
I'm using webpy to create a VERY simple todo list using peewee with Sqlite to store simple, user submitted todo list items, such as "do my taxes" or "don't forget to interact with people", etc.
What I've noticed is that the DELETE request fails on certain inputs that contain specific symbols. For example, while I can add the following entries to my Sqlite database that contains all the user input, I cannot DELETE them:
what?
test#
test & test
This is a test?
Any other user input with any other symbols I'm able to DELETE with no issues. Here's the webpy error message I get in the browser when I try to DELETE the inputs list above:
<class 'peewee.UserInfoDoesNotExist'> at /del/test
Instance matching query does not exist: SQL: SELECT "t1"."id", "t1"."title" FROM "userinfo" AS t1 WHERE ("t1"."title" = ?) PARAMS: [u'test']
Python /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/peewee.py in get, line 2598
Web POST http://0.0.0.0:7700/del/test
When I view the database file (called todoUserList.db) in sqlitebrowser, I can see that these entries do exist with the symbols, they're all there.
In my main webpy app script, I'm using a regex to search through the db to make a DELETE request, it looks like this:
urls = (
'/', 'Index',
'/del/(.*?)', 'Delete'
)
I've tried variations of the regex, such as '/del/(.*)', but still get the same error, so I don't think that's the problem.
Given the error message above, is webpy not "seeing" certain symbols in the user input because they're not being escaped properly?
Confused as to why it seems to only happen with the select symbols listed above.
Depending on how the URL escaping is functioning it could be an issue in particular with how "?" and "&" are interpreted by the browser (in a typical GET style request & and ? are special character used to separate query string parameters)
Instead of passing those in as part of the URL itself you should pass them in as an escaped querystring. As far as I know, no web server is going to respect wacky values like that as part of a URL. If they are escaped and put in the querystring (or POST body) you'll be fine, though.
I am trying to pass an entire, full length/structure URL within my app as an argument inside the app's URL. For example, I want to be able to do something like:
myapp.com/https://www.youtube.com/watch?v=dQw4w9WgXcQ so that I can take the URL entered after my app's home page and store it. However, I think the app is getting confused when the URL pasted has fragments and query arguments (ie: contains # and/or ?) My urls.py looks like this:
url(r'^(?P<url_param>[a-zA-Z0-9_.-/:?=#]*)/$', views.anywebsiteentered, name='anywebsiteentered')
When I try to write a view that looks like below to take the inputted URL and save it inside a model object, I always get the URL truncated before the query and fragment characters, what can I do so that my application picks up the entire URL string?
def anywebsiteentered(request, url_param = 'url_param'):
UrlBlob.objects.create(fullurl=url_param)
For example, the above object created if my app is at myapp.com/https://www.youtube.com/watch?v=dQw4w9WgXcQ only returns https://www.youtube.com/watch and not the query part of the URL. I suspect it is something I am doing with the passing of the URL because when I create this model object manually inside the python-django shell there is no problems at all.
Thanks for any help and hints. I really appreciate it.
If you needed to use some url in "path" area of another url you should escape it's special characters. For example use %3F instead "?". It's called url escaping.
For your purpose would be better pass url as argument like:
myapp.com/?url=http://www.youtube.com/watch?v=dQw4w9WgXcQ
— browser will do necessary escaping in this case.
You can get the query string from request.META:
def anywebsiteentered(request, url_param='url_param'):
full_url = url_param
query_string = request.META['QUERY_STRING']
if query_string:
full_url += u'?' + query_string
UrlBlob.objects.create(fullurl=full_url)
I'm trying to match two strings in an url, but it's not working out likely due to my poor knowledge of regex. I want urls like the following:
testserver/username/
testserver/username/1234/
testserver/username/rewards/
Username would be passed in to the url as a kwarg. Here's what I have:
url(r'^(?P<username>[-\w]+)/$', Posts_Index, name="userposts"),
url(r'^(?P<username>[-\w]+)/photos/$', Photo_Index, name="userphotos"),
url(r'^(?P<username>[-\w]+)/rewards/$', Rewards_Index, name="userrewards"),
url(r'^(?P<username>[-\w]+)/following/$', Follower_Index, name="userfollowers"),
url(r'^(?P<username>[-\w]+)/followers/$', Following_Index, name="userfollowing"),
url(r'^(?P<username>[-\w]+)/(?P<pk>\d+)/$', SinglePost_Index, name="singlepost"),
However, only userposts will be found. If I try to query userphotos or anything below userposts, only the userposts url will be checked, which obviously leads to failure. How can I fix this issue?
From the django docs: Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL.
Thus if you reverse the order of the urls it should work better.
