Django cloudinary image how to add onClick event in tag?
I am successfully creating a Cloudinary image as follows: {% cloudinary photo.filename width='300' crop='fill' class='item_photo' id=photo.filename %} Which results in html img tag: <img class="item_photo" id="xxxxxx" width="300" src="https://res.cloudinary.com/xxx/image/upload/c_fill,w_300/vxxx/xxx.jpg"> However, I want to add an onClick event to the img, but am not able to figure out the correct syntax or perhaps even if it is possible. I would like html tag to look like: <img class="item_photo" id="xxxxxx" width="300" onClick=imageClick('xxxxxx') <=== event variable is same as `id` value src="https://res.cloudinary.com/xxx/image/upload/c_fill,w_300/vxxx/xxx.jpg"> The id and imageClick variable are themselves populated by Django template tag value photo.filename. Some things I've tried: onClick='photoClick(photo.filename)' %} {% with add:'onClick=photoClick('{{ photo.filename }}|add:') as onclick %}{{ onclick }}{% endwith %} |add:'onClick=photoClick('{{ photo.filename }}|add:')' %} How can I construct the onClick=photoClick(xxx) part of this template tag? -

What are the risks of not cycling session keys in Django?
Django cycles the session key upon login. The rationale (that I don't understand) is in this pull request: When logging in, change the session key whilst preserving any existing sesssion. This means the user will see their session preserved across a login boundary, but somebody snooping the anonymous session key won't be able to view the authenticated session data. Cycling the session key is awkward if you wish to easily associate unauth behavior with a later logged-in user. This answer suggests simply disabling cycle_key. What risks are there in disabling cycle_key? (Related to the comment above, or others.) -

Django API and Reactjs 401 Forbidden
I have set up a Django backend that receives calls from a react js frontend. They are deployed on two separate servers. My users can log in and be assigned a token which I can see clearly being stored on the browser properly. This functionality works just fine. Yet when I am making calls (other than to login) to the backend I receive error 401 unauthorized. In order to test the functionality, I set up a basic request that looks as such in ReactJS. //Axios variables required to call the predict API let headers = { 'Authorization': `Token ${props.token}` }; let url = settings.API_SERVER + '/api/test/predict/'; let method = 'post'; let config = { headers, method, url, data: irisFormData }; //Axios predict API call axios(config).then( res => {setPrediction(res.data["Predicted Iris Species"]) }).catch( error => {alert(error)}) Note: setPrediction() is just a react state. This is the related view on the backend. class IRIS_Model_Predict(APIView): authentication_classes = [TokenAuthentication] permission_classes = [IsAuthenticated] def post(self, request, format=None): data = request.data keys = [] values = [] for key in data: keys.append(key) values.append(data[key]) X = pd.Series(values).to_numpy().reshape(1, -1) loaded_mlmodel = PredictionConfig.mlmodel y_pred = loaded_mlmodel.predict(X) y_pred = pd.Series(y_pred) target_map = {0: 'setosa', 1: 'versicolor', 2: 'virginica'} y_pred = y_pred.map(target_map).to_numpy() … -

How to access a serializer attribute from a method with no 'attrs' argument
Im trying to access the participants attribute in my conversation serializer from inside my 'get_other_user' method. My participants attribute returns a list of user dictionaries. However, when I run the code I get model has no attribute 'participants'. Im assuming I have to pass in a, 'attrs' argument in to the 'get_other_user' method, (one similar to the 'def validate(self, attrs) method), then use attrs.get('participants). However, I do not know how to fill in the attrs parameter when calling this method in my get_other_username method. Any advice would be appreciates.
