Access friendlist without taggable_friends permission in Facebook Graph API
I am trying to access the list of friends from facebook that I can display on the Django application made by me. I knoww that there is one permission required called taggable_friends but after reviewing facebook is granting it to me and giving very weird reasons that they found no login button on my application. Even though I have it they still deny. Well, my question is : Does anyone know what can be other way around for getting the facebook friends using the graph API apart from the taggable-friends. Please do not suggest me the read_custom_friendlist and user_friends, as I have checked it and tried to. It gives nothing. Kindly help me. I am using Facebook Graph API v2.10 -
Why the css file can not be found in Django template?
I have created a project in Django. Also, I am using django-allauth for sign up and login. In order to use my own templates with django-allauth, I have created a html file called signup.html in a folder called account inside a folder called templates which is outside of of all my apps (/templates/account/signup.html). That works. I tried to use some custom css file inside signup.html: <link rel="stylesheet" href="/templates/account/signup.css"> It says that the file can not be found. Though, it is located in templates/account. -
Django Rest Framework error: {"user":["This field is required."]

CronJob, django and environment variables
I have built an application for django on Openshift v3 PRO with the django-ex template. It works great. I'm using POSTGRESQL with persistent storage. I need a scheduled cron job to fire every hour to run some django management commands. I'm using the CronJob pod for this. My problem is this: I need to create the CronJob job with the same environment variables that the django pod was created with (DATABASE_, DJANGO_, and others), but don't see an easy way to do this. Any help would appreciate it. -

How to read a file upload from the webpage by django?
This is the first time I develop a website project, and I don't have any experience in frontend and backend before. I've read Django's official tutorial and get some intuition about it, but I have to say frontend is such a horrible thing, I don't have time to learn it carefully because I have to finish the task before the end of this week. Here comes the problem. I have to read a file upload by any user from the webpage, the HTML code was written by other people in the lab like follow: <label>select a file &nbsp;&nbsp;&nbsp;&nbsp; <input id="photoCover" class="input-large" type="text" style="height:30px;"> <button class="btn1 btn-primary" onclick="$('input[id=lefile]').click();"><i class="fa fa-folder-open"></i>&nbsp;&nbsp;浏览&nbsp;&nbsp;&nbsp;&nbsp;</button> </label> I want to know how to process the file selected in the Django views. Here are my thoughts: 1.The selected file must be in some directory on the local machine, maybe I should directly get the path of that file. 2.Should I create a form to handle this problem? Is there anybody could give me a hand or some hints about how to solve this problem? any other resource is appreciated. -
Many foreign keys in a model, better way to do models?
I'm kind of new to django. While writing the models for an app I'm doing, I felt like I was doing something wrong because of all the foreign keys I was using for a single model (ticket model to be specific) My thinking at the beginning was that I wanted each Ticket to keep the information on it's creator, what team this ticket is assigned to and the comments made on the ticket. And other information that don't need foreign keys. Am I doing this right ? I dont know why, but I feel like there is a better way. class Team(models.Model): name = models.CharField(max_length=200) description = models.CharField(max_length=2000) members = models.ManyToManyField(User, through='Team_members') def __str__(self): return self.name class Ticket(models.Model): name = models.CharField(max_length=200) creator = models.ForeignKey(User, on_delete=models.CASCADE) team = models.ForeignKey(Team, on_delete=models.CASCADE) comments = models.ForeignKey(Comment, on_delete=models.CASCADE) #worker = models.ForeignKey(User, on_delete=models.CASCADE) *to be finished description = models.CharField(max_length=500) status = models.BooleanField(default=False) date_opened = models.DateTimeField('date opened') date_closed = models.DateTimeField('date closed',null=True, blank=True) def __str__(self): return self.name class Team_member: team = models.ForeignKey(Team) user = models.ForeignKey(User) date = models.DateTimeField('date joined') class Comment: text = models.CharField(max_length=2000) user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.text -

about IDE, on clonning a github repository. issue: i require a "commit diff" to be cloned instead of the final project
I will explain my own problem so it is easier to understand. I have several books of Django, currently on Django Unleashed by Andrew Pinkham. On the sample project files you have this straightforward project https://github.com/jambonrose/DjangoUnleashed-1.8/ I managed to fork it to my github and clone it on Pycharm professional IDE through its VCS/checkout from version control/github, so I can do certain stuff like right click stuff and see where it leads to within the project etc... The issue I am finding, however is that when reading through the book as the code develops in each chapter, this code isn't saved in the whole parent branch divided by episodes, but it is instead saved as diff commmits, or steps of the process towards the final github project I, for example can link to certain commits as dju.link/a30e354253/organizer/views.py but when I fork this to my account, only the final project which is up gets to my profile and ends up being cloned. For example this final link to a commit I just put leads to a folder called blob which doesn't even exist when i look at the project ....github.com/jambonrose/DjangoUnleashed-1.8/blob/a30e354253/organizer/views.py While a search for blob or a30e354253 on jambonrose's project wont … -
Form not saving object a redirect to new form view
I am attempting to build an app the creates patient data, saves it, and displays it. Problem : When I populate the fields and click save it does not save the object and render data to the document object model. It reloads the page with the field data still in the fields.

django-filters {{ field.label_tag }} not displaying but {{ field }} is
So I'm having a weird issue with Django-filters. I got them working a previous time but now they just aren't. I'm trying to split the fields in a for loop so I can have more control over the CSS of the label_tag. However, the label_tag isn't showing up. But the field itself is. I have absolutely no idea why.

A lightweight django cart app
What's an up to date cart app for django that isn't years old and isn't a full blown framework? There seems to be no middle ground between something like oscar which I definitely don't need or something like satchless which I have no idea how to even start using. All I need is a cart app I plug in and I can process payments using django-payments. Essentially I just want to have a cart I can display on my site, which isn't really e-commerce, but users can create items they pay for and add them to a cart. So, the cart needs to be able to handle different model types and store the current items in the cart with the ability to remove them. I don't know how to roll my own solution for this. Hence, my question. -

The output looks like this: ====================================================================== FAIL: test_get_redirect_url (users.tests.test_views.TestUserRedirectView) ---------------------------------------------------------------------- Traceback (most recent call last): File "users/tests/test_views.py", line 33, in test_get_redirect_url '/users/testuser/' AssertionError: '/en-us/users/testuser/' != '/users/testuser/' - /en-us/users/testuser/ ? ------ + /users/testuser/ As you can see, the issue is that /en-us/ is the prefix being used on the url. Now, I could fix this by adding /en-us/ to my assertions. However, the /en-us/ prefix is incorrect. This is a language code and not the regular language prefix as shown in my settings file. Outside of testing, and using runserver, if I navigate to the /users// url it is prefaced with /en/ not /en-us/ So, the big question is … -
NameError for defined class variable [duplicate]
This question already has an answer here: Nested list comprehension scope 1 answer Below, the artifact_urls class variable is clearly defined, and there is no problem referencing it in a print statement or dict constant, but referencing it from within a list comprehension raises a NameError. Why?!?! Here's the code and output. from otree.api import ( models, widgets, BaseConstants, BaseSubsession, BaseGroup, BasePlayer, Currency as c, currency_range ) class Constants(BaseConstants): artifact_urls = ["Hello, world!"] print(artifact_urls) artifact_const = { "url": artifact_urls[0] } artifact_const = [{ "url": artifact_urls[i] } for i in range(1)] Output: ['Hello, world!'] Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x1085426a8> Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/django/utils/autoreload.py", line 229, in wrapper fn(*args, **kwargs) File "/usr/local/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 107, in inner_run autoreload.raise_last_exception() File "/usr/local/lib/python3.6/site-packages/django/utils/autoreload.py", line 252, in raise_last_exception six.reraise(*_exception) File "/usr/local/lib/python3.6/site-packages/django/utils/six.py", line 685, in reraise raise value.with_traceback(tb) File "/usr/local/lib/python3.6/site-packages/django/utils/autoreload.py", line 229, in wrapper fn(*args, **kwargs) File "/usr/local/lib/python3.6/site-packages/django/__init__.py", line 18, in setup apps.populate(settings.INSTALLED_APPS) File "/usr/local/lib/python3.6/site-packages/django/apps/registry.py", line 108, in populate app_config.import_models(all_models) File "/usr/local/lib/python3.6/site-packages/django/apps/config.py", line 198, in import_models self.models_module = import_module(models_module_name) File "/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 978, in _gcd_import File "<frozen importlib._bootstrap>", line 961, in _find_and_load File "<frozen importlib._bootstrap>", line 950, in _find_and_load_unlocked …
