Method Not Allowed (POST): /login/
I'm trying to get the users data using a form which I have in a .html file called login.html. The code for that is: <form class="register-form" method="POST" action="{% url 'login' %}"> {% csrf_token %} <table> <tr> <td>Username: </td> <td><input type="username" name="username"><br></td> </tr> <tr> <td>Password: </td> <td><input type="password" name="password"><br></td> </tr> </table> <br> <input type="submit" value="Login" /> </form> I've already got a database with a bunch of users where username and passwords are stored. I want to create my own login page that checks agains that database. What I'm trying to do is essentially get the user to the login.html page and then let the user enter the details and check against the database. My urls.py looks like this: from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^register$', include('register.urls')), url(r'^login/', include('login.urls')), url(r'^', include('home.urls')), ] effectively it goes to the login.urls where the urls.py for that is: from django.conf.urls import url, include from django.contrib import admin from login import views urlpatterns = [ url(r'^$', views.LoginPageView.as_view(), name='login'), ] my views.py is: from django.shortcuts import render from django.views.generic import TemplateView from person.models import Person class LoginPageView(TemplateView): template_name = "login.html" def get(self, request, **kwargs): print(request) return render(request, 'login.html') Problem is … -
How to store array of Python dicts in PostgreSQL?
I have a Django project and such array in it: {(0,0):{'a':True,'b':False ... },(0,1):{'a':True,'b':True ... },(1,1):{'a':True,'b':False ... }... } I need to store this array in PostgreSQL database. I thought the ArrayField could help, but I just have no idea how to declare such array. I've read https://docs.djangoproject.com/en/1.11/ref/contrib/postgres/fields/ but there was not my situation. Could you show me an example? -

Django unit upload zipfile
For my project made in Django, I have a page with a form allowing the user to upload a zipfile. Then from this zip file, I open it and read a file from there. I started with the unit tests to validate all cases : - Not a .zip extension - zipfile.is_zipfile() return False - Can't find the file I want to read inside - File inside is invalid For my unit tests, I create different files for each error, and upload it using django.test.Client as so : with open_file('wrong_format.zip') as file: response = self.client.post(url, {'archive': file}) self.assertEqual(response.status_code, 200) self.assertContains(response, '<li>Only zip archived are allowed</li>') But I get the following error : UnicodeDecodeError: 'utf-8' codec can't decode byte 0x99 in position 10: invalid start byte It works fine when I do it from the browser -

Issue in a Django's template
Actually, I know it is impossible in a Django's template, but I would like to execute {{ Perception.objects.filter(loan__request__customer__pk = 207) }} Here is the views I use for that template : class PerceptionIndexView(StaffRestrictedMixin, FrontendListView): page_title = _('Perception') model = Perception template_name = 'loanwolf/perception/index.html' pjax_template_name = 'loanwolf/perception/index.pjax.html' row_actions_template_name = 'loanwolf/perception/list-actions.inc.html' url_namespace = 'perception' def active(self, obj): if obj.is_active: return icon(obj.get_icon(), css_class='green-text', tooltip=_('Active')) else: return icon(obj.get_icon(), css_class='red-text', tooltip=_('Inactive')) def notes_count(self, obj): return obj.notes.count() notes_count_label = _('Notes') def get_change_url(self, obj): return obj.get_absolute_url() def my_view(self, A_pk): filter_perceptions= Perception.objects.filter(loan__request__customer__pk=A_pk) return render_to_response('../template/loanwolf/perception/list-view-#2.inc.html', {'filter_perceptions': filter_perceptions}) I tried to use render_to_response with different path, but nothing happen so far. knowing that my view is located in loanwolf/perception and my template list-view-#2.inc.html is located in loanwolf/templates/loanwolf/perception.

How to use Django's admin Boolean icons in a custom template?
I'm trying to build a django template that at one point displays a boolean variable. However, I want to display an icon instead of the words "True" or "False". I know the Django Admin does this.

Django - object values to jQuery
I have Group model with fields: pay ('Free', 'Paid'). I have two objects: 'Default' and 'Premium'. In my form when I choose Premium for example I use jQuery to add another field to my form: $('#id_group').change(function() { var $this = $(this); if ($this.find('option:selected').attr('value') == '1') { $("#group").html('<ul><li>Some text</li></ul>'); $("label[for='id_kod'], #id_kod").slideToggle("fast"); $("label[for='id_category1'], #id_category1, label[for='id_subcategory1'],#id_subcategory1").slideToggle("fast"); } else { $("#group").html('<ul><li>Some text</li>\ <li>Some text</li>\ <li>Some text</li></ul>'); $("#id_kod").attr("required", "true"); $("#group > ul").addClass('premium'); $("label[for='id_kod'], #id_kod").slideToggle("fast"); $("label[for='id_category1'], #id_category1, label[for='id_subcategory1'],#id_subcategory1").slideToggle("fast"); } }) I know that 'Premium' is 'Paid' and I set this that way. I'd like to automate this because user can create new group with "Free" or "Paid" options. I do not have idea how can I check object value and use it in my jQuery code. Something like Group.objects.filter(id=SELECTED_VALUE).Values('pay'). When user choose "Paid" group addictional form field should appear. Please give me some advice. -

Error in create_group method in a h5py file in python3 (function located in Django REST web service)
I have a function in a web service that was created using Django REST framework, Python3.4. The function would create a HDF5 file with a 2D array, which is contained in a dataset named 'rainfall' inside a group named 'sample_event'. Although the function works well when tested from the VM that contains the web service, it returns error when trying to access as web service.

"Suspicious Operation" calling static files from Amazon S3

Save uploaded files in subfolder depending on request
I have a website, that lets user upload files. These files are attached to a node, which ID is part of the upload request. Since the same file might be attached to different nodes, Django will rename the file by adding a hash to the filename. Thus if a user downloads a previously uploaded file, it won't have the original filename. Is it possible to create a subdirectory (named after the node ID) inside the media folder a file is uploaded? The closest solution I found was to change the System Storage of the FileField, but this is static for all files of that one model. Or is there another, better way to solve the problem with duplicate files? Model: class Attachment(models.Model): node = models.IntegerField(default=-1) file = models.FileField(upload_to=".") View: def file_upload(request): if request.method == "POST": form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): instance = Attachment(file=request.FILES["file"], node_id=request.POST["node_id"]) instance.save() return HttpResponse(instance.file.url) -

After I've plowed through all the errors of depreciated functions I now stumble on an error that I cannot understand: 'No module named migration' I get this error when running (in a virtualenv): - python manage.py runserver and also when I run - python manage.py migrate Traceback (most recent call last): File "manage.py", line 20, in <module> execute_from_command_line(sys.argv) File "/var/www/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line utility.execute() File "/var/www/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 342, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/var/www/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 195, in fetch_command klass = load_command_class(app_name, subcommand) File "/var/www/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 39, in load_command_class module = import_module('%s.management.commands.%s' % (app_name, name)) File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module __import__(name) File "/var/www/env/local/lib/python2.7/site-packages/django/core/management/commands/migrate.py", line 16, in <module> from django.db.migrations.autodetector import MigrationAutodetector File "/var/www/env/local/lib/python2.7/site-packages/django/db/migrations/__init__.py", line 1, in <module> from .migration import Migration, swappable_dependency # NOQA ImportError: No module named migration -
Error while installing 'django_admin_bootstrapped'
I'm having some troubles while trying to install django admin bootstrapp, i've tried using pip install django_admin_bootstrapped on the terminal while being on the project folder, but i got the following message (error) Collecting django_admin_bootstrapped Requirement already satisfied: setuptools in /Users/Camilo/anaconda/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg (from django_admin_bootstrapped) Collecting Django<1.9,>=1.8 (from django_admin_bootstrapped) Using cached Django-1.8.18-py2.py3-none-any.whl Installing collected packages: Django, django-admin-bootstrapped Found existing installation: Django 1.10.6 Uninstalling Django-1.10.6: Exception: Traceback (most recent call last): File "/Users/Camilo/anaconda/lib/python3.6/shutil.py", line 538, in move os.rename(src, real_dst) PermissionError: [Errno 13] Permission denied: '/Users/Camilo/anaconda/bin/__pycache__/django-admin.cpython-36.pyc' -> '/var/folders/t7/kjwv967n085gdfjg9bjz2bxh0000gn/T/pip-o6dmj5ut-uninstall/Users/Camilo/anaconda/bin/__pycache__/django-admin.cpython-36.pyc' Could affect the fact that i'm working with python 3.6 but the project is done in python 3.4? Any help would be really appreciate.
