Getting error : 'admin' is not a registered namespace, on trying to access the password reset view
I created a password reset view following "https://simpleisbetterthancomplex.com/tutorial/2016/09/19/how-to-create-password-reset-view.html " this link. I used the urls for class based views since django uses CBVs in the version 2.1 and above. It seemed to work fine, but today I am getting the above stated error. I have commented the admin url,on uncommenting it the password_reset view works, but through the django registration and uses it's own template regardless of the templates I have created.

Get record's age in second if older than 5 minutes in Django (with PostgreSQL database)
I'm retrieving all records, and I would like to display the record's age for those records that are older than 5 minutes. Here's my current code: Interfaces.objects.all() .annotate( age = (datetime.utcnow() - F('timestamp')), # 0:00:08.535704 age2 = Epoch(datetime.utcnow() - F('timestamp')), # 8.535704 # age3 = int(Epoch(datetime.utcnow() - F('timestamp'))/300), current_time=Value(str(datetime.utcnow()), output_field=null_char_field), ) .order_by('age','ip') age and age2 both work, but the problem is that I want the records that are older than 5 minutes sorted by age, and the rest by ip So I'm trying to set age to 0, if it's less than 5 minutes. Is there a way to do it? -

NoMatchReverse error ListView to DetailView can't seem to pass url parameters
I have been struggling with this problem for over a day now. I truly don't understand what to look for when it comes to NoReverseMatch errors. Every time I supply an answer to the error, i get a new error that I don't know how to deal with. Would really appreciate some help with understanding how to debug this issue because I am at a loss right now. I am building a website that has two apps. 1. The main website and 2. a Blog. I created the blog app recently and hooked up the urls so that from the home page, you can go to the blog home (a listview) and then all I want is to make it so that users can click on the title of the article that interests them, and it will display the text and other info associated with the article. The problem is I continually keep getting NoReverseMatch errors on either the blog home page or the blog detail view page and I have no idea where to even begin in troubleshooting it. I am new to OOP, Django, and python and so this is all very disorienting. My most recent error I … -

How to convert Database records to table using Pandas

pass variable from home flask app to remote flask app python
I have two flask files. One is home.py and the other is remote.py. The remote.py will be on another computer in LAN which acts as a server. The home.py will be in my computer. In the home.py, i pass the url for accessing the remote.py file and if the url gets accessed,the home.py executes the route for adding two numbers and store the result in c variable and sent c to the remote.py file. In remote.py file, I have a route for getting c value from the home system and store it in a get_c variable.

Reverse generic relations and Generic Relations
in a simple scenario, where i have many measurements table that describe the measurements that comes from a specific protocol and every measurement it's linked to the respective parent device, i was looking for an optimization of my database, putting all the measurements into a table and reference from this table the respective device. Now, keeping in mind that this table it's heavily used in read/write and especially in filtering operations, i was looking for a smarter solution...i've found the Django Generic Relations and Reverse Relations...but this approach it doesn't convince me at all... because, as now, with a simple select with a where the problem it's solved...but using a generic relation, the ORM will generate a lot of inner joins (if i'm not wrong...) and this is an aspect that i want to avoid. So, anyone with smarter idea? My goal is to remove tons of if into my code that at this time are used to decide what table it will be queried based on the protocol type -

How to force logout when Knox created token has expired?
I developed my Django based webapp with token authentication by following this tutorial of Brad Traversy (https://www.youtube.com/watch?v=0d7cIfiydAc) using Knox for authentication and React/Redux for the frontend. Login/logout works fine (here is Brad's code: https://github.com/bradtraversy/lead_manager_react_django/blob/master/leadmanager/frontend/src/actions/auth.js --> logout using a POST request), besides one issue: When the user stays away from the computer for a long time, the token expires in the meanwhile. So when the user returns he is still in the logged in zone of the website, but as soon as he opens a React component with data loading from the DB a 401 error is thrown in the console ("Failed to load resource: the server responded with a status of 401 (Unauthorized)"). Then the user has to go on "logout" and login again. This is not optimal, I would prefer that after the user returns, the system realizes the token expiry and logs the user automatically out. I have thought of the following approaches, but I am not sure how to implement it or which one is best: 1) For every API request: if the answer is 401 --> logout (this might also log the user out in case the token has not expired, but if there is some … -

use a web-based image as background with inline style tags, django
im using django2.2 and python3. i only mention that in the event that, somehow, thats apart of why none of this is working. i have a file, search.html. literally the only code in the entire file is as follows: <html> <body style="background:url("https://www.coolpix.com/image123")> some text here </body> </html> the goal here is simply to render the image as the background for the page, yet the only thing that shows up is the text. initially i tried to make this work by using my CSS file, but i couldnt get it to work for some unknown reason. so the next step i took was to just go directly into the html file and make it show up that way. ive tried several different images from several different websites, and nothing seems to work. what could i possibly be doing so wrong? -

Django default value in model based on data that hasn't been loaded yet
When creating migrations for Django I'm running into an instance where I need to set the default value for a custom user based on another table. # models.py def get_default_item(): return Item.objects.filter(name='XXXX').first().id class CustomUser(AbstractUser): # ... item = models.ForeignKey(Item, on_delete=models.CASCADE, default=get_default_item) # ... I'm running into two issues: I need to ensure that the table for Item is already created. I think I can do this using dependencies. I need to ensure that the Item "XXXX" is created before it is referenced. Unfortunately this can't happen until I migrate the data over because the Item IDs need to be consistent with the old system and (unfortunately) I can't use id 0 with a Django / MySQL combination because that has special meaning. Is there a way to tell the migration "don't worry about this default for now, you'll get it later"? -
How to convert Python datetime object to specific timezone in Django Rest Framework?
I'm working on an existing codebase which implements an api using Django and the django-rest-framework. When you post a datetime like this: 2019-06-21T10:35:46+02:00 it is stored in UTC as 2019-06-21 08:35:46+00 (as expected). This is because I've got USE_TZ = True. When I serve the data, I also want it to be converted to the localised format again (2019-06-21T10:35:46+02:00). So following this tip I implemented it like this: class DateTimeFieldWihTZ(serializers.DateTimeField): """ Class to make output of a DateTime Field timezone aware """ def to_representation(self, value): value = timezone.localtime(value) return super(DateTimeFieldWihTZ, self).to_representation(value) class PeopleMeasurementSerializer(HALSerializer): class Meta: model = PeopleMeasurement fields = [ '_links', 'id', 'timestamp', 'sensor', 'count' ] timestamp = DateTimeFieldWihTZ(format='%Y-%m-%d %H:%M:%S') But this serves it as 2019-06-21 08:35:46. How can I serve it as 2019-06-21T10:35:46+02:00 again? -
