Unable to send whole object to another Django views
As I have seached through StackOverflow and already tried all those answer still not work for me. My project is to use telnetlib to connect device via Django webapp. I stuck in passing telnet object between views with request.session. Class A(TemplateView): def post(self, request, *args, **kwargs) obj = telnetlib.Telnet(host,timeout) request.session['obj'] = obj return render(request,'next.html',{}) Class B(TemplateView): def post(self, request, *args, **kwargs) obj2 = request.session.get('obj') ... ... Then I got error: Object of type 'TelnetThing' is not JSON serializable And already tried to serialize it to json (which I kind of no idea what it is) and still not working 'TelnetThing' object has no attribute '_meta' Anyone knows how to fix this or passing whole object this way is practical? -
List Field serializer giving 'ManyRelatedManager' object is not iterable error with M2M field
My models.py looks like this: class IP(models.Model): name = models.CharField(max_length=30, unique=True) address = models.CharField(max_length=50, unique=True) class IPGroup(models.Model): name = models.CharField(max_length=50, unique=True) ips = models.ManyToManyField('IP', through='IPGroupToIP') class IPGroupToIP(BaseModel): ip_group = models.ForeignKey('IPGroup', on_delete=models.CASCADE) ip = models.ForeignKey('IP', on_delete=models.CASCADE) Now, in order to create an IPGroup, I have the following serializer: class IPGroupCreateSerializer(serializers.ModelSerializer): ips = serializers.ListField() class Meta: model = IPGroup fields = ['name', 'ips'] @transaction.atomic() def create(self, validated_data): ips_data = validated_data.pop('ips', None) ip_group = IPGroup.objects.create(name=validated_data['name']) if ips_data: for ip in ips_data: ip_obj, created = IP.objects.get_or_create(name=ip['name'], address=ip['address']) IPGroupToIP.objects.create(ip_group_id=ip_group.id, ip_id=ip_obj.id) return ip_group My views are a simple class based view as follows: class IPGroupCreateView(generics.CreateAPIView): queryset = IPGroup.objects.get_queryset() serializer_class = IPGroupCreateSerializer My JSON payload looks like this: { "ips": [{"name":"example.com", "address":"10.1.1.9"}], "name": "ipgroup1" } This how ever gives me an error stating: TypeError at /api/v1/ip-group/ 'ManyRelatedManager' object is not iterable The strange thing is that when i check the DB, the IPGroup is created along with the M2M ips. So, the code is working as expected but the view is somehow returning a 500 server error instead of a 201 created. What am i doing wrong ? -
How to have a multiple parameters on a request function in python
How can we have multiple paramets in a request in python like for example from my code it has url and auth i wanted to add a header but it results to error unexpected keyword argument. I wanted to add a header my header has the access key. Code r = requests.post('http://139.89.156.42:5033/api/1.0/session', auth=HTTPBasicAuth('fff', '123456')) for example i wanted to add a header -
Converting UUIDField to CharField
This is currently what I have in my models.py: class Campaign(models.Model): campaign_id = UUIDField(auto=True) name = models.CharField("Campaign Name", max_length=255) class CampaignResponse(models.Model): campaign = models.ForeignKey(Campaign) user = models.EmailField("Email", max_length=200) response = models.TextField() Recently I was thinking of changing the campaign_id in the Campaign model from UUIDField to CharField instead, but when I tried to do so, I noticed the data for campaign_id is being altered (e.g. the data was "7182c679f72844ca83c9648a120bb066" when UUIDField is being used, but it now becomes "7182c679-f728-44ca-83c9-648a120bb066" after converting it to CharField). Is there some steps I have to follow where I can convert that UUIDField to CharField without changing the data and ensure the relationship between Campaign and CampaignResponse is not broken? -

update choices option of a field instance, not of the entire field
I have a model field with choices: class MyModel(models.Model): myfield = models.CharField(max_length=1000, choices=(('a','a'),('b','b')) I know that I can access in forms this specific field and override its choices option like that: self.instance._meta.get_field(field_name).choices = (('c','c'),('d','d')) but that will change the choices for the entire model, not for an individual instance. What is the correct way to do it for one specific instance only or it is not possible? -

How to prevent employees to work from home on the company's django application
I built an ERP for a small company using Django 1.11. They are expanding now and have other companies joining them and now also use the system I built. The problem now is that some of the companies do not want their employees to be able to work from outside of the company's premises; remotely. Is there a way to achieve this on the Django application? Is there a way to tweak the Django's allowed_host setting for this purpose? Should I be checking for the location of the user connecting to the app? If so, how do I prevent the app from being fooled by those using a VPN service? -

Revert back to the default Django admin template
I recently decided to style the Django Admin dashboard with Bootstrap. After a successful attempt, I wanted to switch back to the way it looked before adding bootstrap so I removed the boostrap_admin from the INSTALLED_APPS. However, when I restarted the server, the template was all messed up. -
What are the limitations on deploying a tkinter gui as a web app?
I have written a tkinter gui in python which involves access to image and excel files. It also has a quite a few buttons and frames to deal with. I built the gui using the pillow library for images, and the openpyxl and pandas library for dealing with excel. I also used the pdf2page library, but I already have a tool to convert pdf to png. Is there a way I can deploy my gui as a web app or run it on a website? If not, is there someway I can recreate a similar interface with the same underlying python code? (that is the code not used to make the tkinter widgets) I'm planning on using the Django framework - - or something easier - - and A2 web hosting (or similar quality web hosting)
