How to replace ALL django "Status Code Exception" pages
Any Status Code exceptions like 404, 403, 405, 500, CSRF and more return their own "Django" specific pages, a few are HTML. handler403, handler404, and handler500 exist and can be easily overridden, but there are a lot of these "hidden" Django pages that are being returned upon error, an example is 405 (method does not exist) or CSRF (if no CSRF token is in the request) and probably many more. Is it possible to have a custom view (such as just a generic 404 return) for ALL of these "hidden" Django HTML pages? -
Django Cannot Connect to Remote MySQL Server
I am running a Django and attempting to connect to a MySQL server at my university. First of all: In order to connect the database, I normally SSH into a remote server (with authentication) of theirs, and then run MySQL and enter my MySQL authentications. This works without an issue, in Terminal as well as DataGrip. Now, using PyCharm, I have installed mysqlclient in the intepreter and changed my settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': '[DB_NAME]', 'USER': '[DB_USERNAME]', 'PASSWORD': '[DB_PASSWORD]', 'HOST': '[REMOTE SERVER ADDRESS HOSTING MYSQL]', 'PORT': '3306', } } Also using PyCharm, I have even opened up a data source in the Data Sources Tool Window and connected through SSH tunnel and MySQL authentication to the database. This is successful, and it is possible to make queries. However, I try to run: manage.py check and I receive: Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site- packages/django/db/backends/base/base.py", line 213, in ensure_connection self.connect() File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/backends/base/base.py", line 189, in connect self.connection = self.get_new_connection(conn_params) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 274, in get_new_connection conn = Database.connect(**conn_params) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/MySQLdb/__init__.py", line 86, in Connect return Connection(*args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/MySQLdb/connections.py", line 204, in __init__ super(Connection, self).__init__(*args, **kwargs2) _mysql_exceptions.OperationalError: (2003, "Can't connect to MySQL server on '[REMOTE SERVER … -
django/rest: User registration API shows""Authentication credentials were not provided."
I'm trying to create an API for user registration in django 1.11.5 and python 3.5.

Django template custom form using text area not working
I am using custom template for django form, so i loop over the form fields and create hidden textarea boxes. On hitting the submit button i call the function save code which fills in value of textarea. Earlier i was using input html instead of textarea and it was working fine but I need multiple line value in my form (html input is only single line) so i had to change it to textarea But now probably i am getting 'this field is required' error! (the procedure is same, when i had input tag i did performed document.getelementbyid('id-name').value = required stuff) So i am confused why is it not working with textarea <form method="post" action="{% url 'problem' problem.problem_ID %}"> {% csrf_token %} {% for field in code_form %} <textarea id="{{ field.id_for_label }}" value="{{ field.value }}" style="visibility:hidden;"></textarea> {% endfor %} {% buttons %} <button onclick="save_code()" type="submit" class="btn btn-success center-block">Submit editor</button></td></tr> {% endbuttons %} </form> -

(Before this I only had CharFields in the model and no widgets) I've searched other similar questions but haven't been able to find anything to solve this issue. At present I just keep getting the error message I coded in views.py.
