Django: dynamic URL for user profiles
So I'm trying to make a pretty conventional dynamic URL profile pages for my users. So eg. www.website.com/profile/(username) I am getting an error of NoReverseMatch when I enter a valid username, and I do not know why. Here are snippets of my code urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^signup/$', accountsViews.signup, name="signup"), url(r'^logout/$', authViews.LogoutView.as_view(), name='logout'), url(r'^login/$', authViews.LoginView.as_view(template_name='login.html'), name="login"), url(r'^find/$', findViews.find, name="find"), # url(r'^profile/$', accountsViews.profile, name="profile"), url(r'profile/(?P<username>.+)/$', accountsViews.profile, name="profile"), url(r'^$', views.home, name="home"),] views.py def profile(request, username=None): if User.objects.get(username=username): user = User.objects.get(username=username) return render(request, "profile.html", { "user": user, }) else: return render("User not found") html file {% if user.is_authenticated %} {% url 'profile' as profile_url %} <li {% if request.get_full_path == profile_url %}class="active"{% endif %}><a href="{% url 'profile' %}"><span class="glyphicon glyphicon-user"></span> Profile </a></li> <li><a href="{% url 'logout' %}"><span class="glyphicon glyphicon-log-out"></span> Log Out</a></li> {% endif %} Also it if it helps, the error message is highlighting the "{% url 'profile' %}" part as the error, and claiming that it does not have a reverse match. However, in my urls.py, you can clearly see that I have done name="profile" Any help would be greatly appreciated. Thank you! -

Django rest framework json web token logout function
First of all, i am still new to django rest framework jwt so pls excuse my stupidity if im wrong. Im wondering about how to create a logout function for jwt as when user want to logout and switch account, they will need this function. Based on the what i seen in many other logout post, - there is no need for logout function as the token isnt save on server side so closing and opening will result in having to login again. - jwt is using expire time for it so it will logout when the token has been expire , provided if the verify token is set to True But what i want is to have like a remember me function where user will stay login when they close and open again, as one of the suggestion is turn the verify token to false or set expire time to weeks. But then how does the user logout if the token expire time hasnt reach yet ? As i am using jwt and djoser, the logout function of djoser is for drf only and not for jwt.

Create an list/dictionary of form fields in Django
I want to create a list of unique radio select options for a game in Django that exponentially increases with each round. So in round 1, the player has 1 radio button to select from. Round 2, the player has 2 radio buttons to select from. Round 3, the player has 4 radio buttons to select from. Crucially, each of these forms needs to have a unique identifier so that the player can select all options for a particular round. For example, for round 3, my form contains the following code: <tr> <td class="tb" rowspan="2"><p {% formfield player.r3_decision1 with label="" %}</p></td> </tr> <tr> <td class="tb" rowspan="2"><p {% formfield player.r3_decision2 with label="" %}</p></td> </tr> <tr> <td class="tb" rowspan="2"><p {% formfield player.r3_decision3 with label="" %}</p></td> </tr> <tr> <td class="tb" rowspan="2"><p {% formfield player.r3_decision4 with label="" %}</p></td> </tr> Player is then declared as a class in models.py, with player containing each of the form fields defined above as attributes. class Player(): r3_decision1 = models.CharField( choices=['A Option A','B Option B'], widget=widgets.RadioSelectHorizontal(), blank=False, initial='blank' ) r3_decision2 = models.CharField( choices=['A Option A','B Option B'], widget=widgets.RadioSelectHorizontal(), blank=False, initial='blank' ) r3_decision3 = models.CharField( choices=['A Option A','B Option B'], widget=widgets.RadioSelectHorizontal(), blank=False, initial='blank' ) r3_decision4 = models.CharField( choices=['A Option A','B … -

how to redirect "print" command output to a file without changing the python code?
I want to redirect all the output of my django app to a file Firstly, I tried: python manage.py runserver 0.0.0.0:8000 >test.log 2>&1 But it doesn't redirect the output of print command. For example, in my code there is a statement: print ('query_content:') using command: python manage.py runserver 0.0.0.0:8000 I can see that 'query_content:' is printed out in the screen. But with : python manage.py runserver 0.0.0.0:8000 >test.log 2>&1 In the test.log, there are only something like this: [05/Nov/2017 20:38:20] "GET ... HTTP/1.1" 200 22404 [05/Nov/2017 20:38:26] "POST ... HTTP/1.1" 200 13 [05/Nov/2017 20:38:26] "GET .... HTTP/1.1" 200 16800 [05/Nov/2017 20:38:30] "GET ... 200 22430 ...

Images not showing up with template tags in Django templates
I'm trying to display a user-uploaded image on my HTML template. I tried a bunch of template tags but none of them seem to be working. All the settings appear to be configured correctly. User-uploaded images are correctly uploaded to project_name/media/ settings.py MEDIA_URL = '/media/' MEDIA_ROOT = 'project_name' # Are the STATIC settings affecting the media settings? media is for user uploads so I don't think so?

Django DateTimeField Chunking, Averaging, and Reformatting
Here is the model I'm working with: class BTCPrice_kraken(models.Model): """ Defines BTC Price Model - Kraken """ id = models.AutoField(primary_key = True) date_time = models.DateTimeField(auto_now = True) code = models.CharField(max_length = 3) last_trade = models.FloatField() last_trade_volume = models.FloatField() ask = models.FloatField() ask_lot = models.FloatField() ask_whole = models.FloatField() bid = models.FloatField() bid_lot = models.FloatField() bid_whole = models.FloatField() open = models.FloatField() high = models.FloatField() high_24 = models.FloatField() low = models.FloatField() low_24 = models.FloatField() volume = models.FloatField() volume_24 = models.FloatField() I need a way to pull ranges from date_time, store all the keys in that range, average the data from keys in the range, and reformat the date_time response to look better than it does raw. For example: I want a 15 minute chunk of time from the DB (the objects are added in 1 minute increments). I want to average all the objects in this chunk and return the averages by column label. And list them by (%d, %m, %y, %h%h, %m%m). How would I go about building query's (preferably with list comprehension and django's built in db modelling) to do this?

Python/Django: How to handle simple search in advanced search engine?
I am working on advance search engine that allow multiple-layered of search(advance search) but I am not sure on how to carry simple search with the search form that contain multiple search fields. E.g: In the form I got a textbox, a dropdownlist that contain several types of fruits and a submit button. The problem is when I decide just to carry a simple search by just simply enter some string into the textbox without choosing the types of fruit and leaving it as the default value " ", when I submitting the form it generated URL: "http://127.0.0.1:8000/result/?q=something&fruit_type=+". Is there a way to remove the "&fruit_type=+" from the URL? <form action="/result/" method="get"> <input type="text" id="search_box" name="q"/> <input type="submit" id="sbm_button" value="SEARCH" class="inputbtn"/> <br /> <select name="Fruits"> <option value=" ">Fruits</option> <option value="apple">Apple</option> <option value="orange">Orange</option> </select> </form> Below is the view.py file: def search(request): if 'q' in request.GET: q = request.GET['q'] fruit_type = request.GET['Fruits'] return render(request, 'result.html', { 'query' : q, 'fruit' : fruit_type, }) It will return the q and fruit_type to result.html with the generated URL which had mentioned above. Is there a way to ignore the Fruits dropdownlist within the form(submitting the form and ignoring the dropdownlist)? Thank you. -
How to setup simple token based authentication in Android?
I want to setup a token based authentication in Android. The way I want/imagine this to work is like this: The Android client makes a POST request to the server together with the token, client_id, client_secret which it retrieved from the Account Manager.. The server reads the token, finds the user associated with the token and processes the POST request. If the POST request arrived without a token in step 2, the server creates the User, a token for the User and sends that token to the client which stores it in the AccountManager for future use. The server will ofcourse, before returning the token to the client, also process the POST request as in step 2. Is that a common technique? That's what I understood this Django Rest Framework article describes. Let me know please if this is the way to go. Otherwise, what do I do? I prefer not to use passwords at all. Why use passwords if the user has a phone with a Google Account? -

Django: function not being executed randomly but only sometimes
Working on developing an online game that is based around a user clicking a button and the game timer resetting to 10 seconds if it is already under 10 seconds (like auction sites), setting that user's username as the top user for the game, and using 1 of that user's tokens. The button works almost all of the time, but occasionally when a user clicks the button, a token of theirs will be used, but the timer will not reset to 10 seconds if it is already under 10 AND the top user for the game will not be updated to display their username. Here is the function that handles the button click on the game page. If the user does not have any tokens it will redirect them to the store page. If the user is already the top user or the game is over (game_object.status = 0) then they will simply be redirected back to the same page without a token being played or the game being updated: def game_page(request, game_id): game_object = Game.objects.filter(id=game_id)[0] context = {'game_object': game_object} if request.GET.get(str(game_object.pk)) and request.user.profile.get_tokens() > 0: if game_object.get_top_user() != request.user.username and game_object.status == 1: request.user.profile.use_token() game_object.update_game(request.user.profile.user) # fail safe if …
