How to port a Django web app in mobile (iOS & Android)
We have a working WebApp developed with Django, Python and Vue.Js. The application is working ok when it is opened in Mobile devices but we need to do lot of tweaking UI to make it compatible to mobile devices everytime.

Map Flask API and Django app to same database but different tables
I have a database model which is written in Django ORM and the same database is used by Flask using SQLAlchemy for another microservice (where I need only 2/3 new and 1 exiting table) to store and query some data. So when from my Flask API, I run this command- $ flask db migrate $ flask db upgrade I can see that from migrations/versions, it is trying to delete existing tables of my Django app which I don't want to do. So my question is how to run/use Flask SQLAlchemy ORM without touching existing tables of Django app? Also From my Flask app, I want to refer to some of the existing tables of the Django app but am not sure how to do those without creating models on the Flask app because those models are already created by Django APP. N.B For a particular reason I don't want to separate the Flask API to another database -
How to display default value for models.FileField() in template CreateView?
How do I display the default value for models.FileField()? (ref) class MyModel(models.Model): myfile = models.FileField(upload_to='mydocs', default='myfile.txt') FieldField has an undocumented feature that allows a default value to be set using default=. This is a reference to an existing file, usually in the static root. The default form widget for this field is a ClearableFieldInput (ref), which uses django/forms/widgets/clearable_file_input.html as a template: {% if widget.is_initial %}{{ widget.initial_text }}: <a href="{{ widget.value.url }}">{{ widget.value }}</a> {% if not widget.required %} <input type="checkbox" name="{{ widget.checkbox_name }}" id="{{ widget.checkbox_id }}"> <label for="{{ widget.checkbox_id }}">{{ widget.clear_checkbox_label }}</label> {% endif %}<br> {{ widget.input_text }}:{% endif %} <input type="{{ widget.type }}" name="{{ widget.name }}"{% include "django/forms/widgets/attrs.html" %}> However, if default is set (initial being blank), the default value is not shown in the template, which can be confusing to the viewer. They think the field is empty, then on create() the default value is set. I am assuming that the default value is not passed to the template? If so, how can I modify the FileField to pass it? If not, how can I reference it? -

I am facing a issue right now on API post for @api_view[('POST'). I have the following codes: models.py class Job(models.Model): datetime = models.DateTimeField(default=timezone.now) combinedparameters = models.CharField(max_length = 1000) serializers.py class JobSerializers(serializers.ModelSerializer): class Meta: model = Job fields = ['combinedparameters'] As you can see there is only 1 field. But i dont know how to set up my @api_view['(POST)'] to do the same thing as my html because my html for this looks like this: Upon clicking the save button, I have to get the individual inputs from the textbox, textarea, dropdown box and convert it into the following : Example - {'device': 177, 'configuration': {'port_range': 'TenGigabitEthernet1/0/1,TenGigabitEthernet1/0/2,TenGigabitEthernet1/0/3,TenGigabitEthernet1/0/4,TenGigabitEthernet1/0/5', 'port_mode': 'Access', 'port_status': 'Disabled', 'port_param1': 'Test\r\n1\r\n2\r\n3', 'port_param2': 'Test\\n1\\n2\\n3'}} But how do I do the same thing in my API view if it doesnt follow how my html look like with so much input areas? -
Why graphene enum returns value instead key for my ENUMS key?
When i post data it return the value of the enum For example when i choose PL it returns the "Poland".I want to get the key of the enum instead of the value. I need PL instead of "Poland.
