ODBC Driver Manager Data source name not found and no default driver specified
I have problem connecting my 64 bit laptop with a database. I am working in a django project and my database (sql server 32 bit) is in a separate server. I have included the following in my settings file in Django. DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'sales', 'USER': '*******', 'PASSWORD': '*********', 'PORT': '1433', 'HOST': 'xx.xx.xxx.xxx', 'OPTIONS': { 'driver': 'SQL Server Native Client 11.0', }, } } I have tried installing "ODBC Driver 11 for SQL Server" in my laptop.

If so how can I handle this without changing the entire laptop system to 32 bit?Also, I haven't installed sql server in my laptop. Should I need to install sql server in my laptop also? -

How to display form errors properly?
Here i am trying to display form's errors and the below code works also but the problem with this is when the form throws the field errors it also clears all the the previously added value from form.I looked through all the solution in this link https://docs.djangoproject.com/en/2.2/topics/forms/ but all the solution works as same. What i really want is to throw the field errors like the django {{form.as_p}} or {% bootstrap_form form %} throws, in my own custom forms.How it can be possible ? {% for field in form %} {% if field.errors %} <div class="alert alert-danger"> {{ field.label }}: {{ field.errors|striptags }} </div> {% endif %} {% endfor %} <div class="box-body"> <div class="row"> <div class="col"> <form action="{% url 'do_something' %}" method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="form-group"> <b>Name</b> <div class="controls"> {{# form.name.errors #}} <input type="text" name="name" class="form-control"> </div> </div> <div class="form-group"> <b>Address</b> <div class="controls"> <input type="text" name="address" class="form- control"> </div> </div> -

How to create a Django REST Framework View instance from a ViewSet class?
I'm trying to unit test Django REST Framework view set permissions for two reasons: speed and simplicity. In keeping with these goals I would also like to avoid using any mocking frameworks. Basically I want to do something like this: request = APIRequestFactory().post(…) view = MyViewSet.as_view(actions={"post": "create"}) self.assertTrue(MyPermission().has_permission(request, view)) The problem with this approach is that view is not actually a View but rather a function which does something with a view, and it does not have certain properties which I use in has_permission, such as action. How do I construct the kind of View object which can be passed to has_permission? The permission is already tested at both the integration and acceptance level, but I would like to avoid creating several complex and time-consuming tests to simply check that each of the relevant actions are protected. -

Use multiple databases in Django having the other database contain tables not created by any model
Here are my questions and if you want to know the details, kindly refer further below (Sorry for the long post, I wanted the inquiry to be as detailed as possible): Questions Is it possible to retrieve data from an external database and use those inside your Django project even if the tables in that database are NOT created as models? If so, what's the basic concept to achieve such. If NOT, then the workaround left is to use the SAME DATABASE as the remote one, and save all models of the django project into a specific schema in that database? So we are trying to forcibly implement Cross-database referencing with a remote database my_remote_db, that contains tables which are not created by a Django model. We've read the Django doc telling it currently cannot handle such referencing method, but the fact we can define multiple databases in settings.py makes us optimistic that there is somehow a workaround. Databases as defined in our settings.py django_project_db - main database (the one used by our Django project for its models) my_remote_db - the remote database. Several applications are using this database e.g. our Scout and PHP applications, etc. What we want to … -
