How to authenticate the user on his requests after login in django using TokenAuthentication from drf
I have implemented an endpoint for login, using the django-rest-framework and TokenAuthentication. What i want, is after the login, the user to be authenticated and can navigate on the website. I know that any get request on any protected using authentication uri should contain the token in the headers, so that the user can be authenticated. Everything is fine with that, if i could do all the get requests adding the token manually. But what i do not understand is, how can i add the token in the headers when for example the user manually does the request by writing the url? Let's say that the uri /api/ is protected and requires an authenticated user. The user logs in, and i save the token either on the cookies or in the localstorage. Now the user does a http get request on /api/. The token is not placed in the headers, so the response is: "Not authenticated". So the question is, how can i add the token on any subsequent request after user logs in successfully? Maybe the backend could check the cookies for a valid token, but isn't there any better and safer solution than this? -

How to render dictionary new entry as new row of table in django?
I am having a difficulty implementing something that seemed quite straightforward in the beginning. More specifically, I want to upload a file in a folder and rename it. After renaming it I want to display a row in a table, which contains 3 columns. First column should display the old name of the file, second column should display the new name of the file and then third column should display a download button. I want the table to display this for every file that I upload (for instance if I have uploaded 5 files I wanna see 5 rows in the table) This is my upload_file view: def upload_file(request): filedict = {} oldname = "" newname = "" if request.method == 'POST': uploaded_file = request.FILES['document'] fs=FileSystemStorage() oldname = fs.save(uploaded_file.name,uploaded_file) newname = "new"+oldname global counter filedict['counter'] = { 'oldname': oldname, 'newname' : newname } counter+=1 return render(request, 'files/renamefiles.html',{'names': filedict}) and this is the table in my template renamefiles.html: <div class="mt-5"> <table class="table table-hover"> <thead> <tr> <th scope="col">Source File</th> <th scope="col">Renamed File</th> <th scope="col">Action</th> </tr> </thead> <tbody> <tr> {% for key, entry in dictionary.items %} {% for key2, data in entry.items %} <th id="filedata">{{data}}</th> {% endfor%} {% endfor%} <th><a class="btn btn-sm btncolor">Download … -

makemigrations does not create the trough model

How to send multiple objects through HttpResponse or JsonResponse in django
I have two objects influencer_data and user_list in my views function.I want to send both influencer_data and user_list through the HttpResponse method. My views function is: def index(request): influencers = Influencer.objects.all() influencer_data = serializers.serialize("json",influencers) user_list = UserList.objects.all() user_list = serializers.serialize("json",user_list) context = { 'influencer_data':influencer_data, 'user_list':user_list, } return HttpResponse(influencer_data,user_list, content_type='application/json') When I pass both influencer_data and user_list I get the error __init__() got multiple values for argument 'content_type' When I change the return HttpResponse statement to return HttpResponse(context, content_type='application/json') I get influencer_datauser_list i.e just the key values from the dictionary When I change the return statement to return HttpResponse(json.dumps(context), content_type='application/json') I get the output as: "influencer_data": "[{\"model\": \"influencer_listings.influencer\", \"pk\": 8794, \"fields\": {\"full_name\": \"F A I Z S H A I K H \\ud83c\\udf08\", \"username\": \"mr_faizzz_07\", \"photo\": \"\", \"email_id\": \"\", \"external_url\": \"\", \"location_city\": \"Mumbai\", \"categories\": \"\", \"hashtags\": \"['#foryou', '#blessyou', '#all', '#faizanshaikh', '#keepsmiling', '#blessed', '#look', (The Json object becomes a string) How should I deal with this? -
Overriding the save method of multiple Django classes without making the change in each individual class
I have a django project set up in which I have 6 (and will possibly add more in the future) tables. I need the admin interface setup such that whenever I update or add an object to any of the models, it writes data to a file from the LogEntry class. I have chosen this method because post save signals will run on server start-up (I have dockerized this app and am importing tables into the postgres database from pre-existing csv files) and they throw errors. In order to achieve the functionality desired, I put the following in my models.py file. class ModdedModel(models.Model): def save(self, *args, **kwargs): changes_file = ("new_changes.txt","w") content2 = LogEntry.objects.all() changes_file.write(content2) super(ModdedModel, self).save(*args,**kwargs) I then inherited this model for all subsequent tables that I want to create using the Django ORM. However this error appears, SystemCheckError: System check identified some issues: ERRORS: mdp.Variants.variants: (models.E006) The field 'variants' clashes with the field 'variants' from model 'mdp.moddedmodel'. I assumed maybe there was some namespace error and changed the field name to variantss to check if it would make a difference but I then got this instead Did you rename variants.variants to variants.variantss (a CharField)?

Typescript inlined in Django html

Restructure existing project to have a separate application with shared modules
This is my first job and I am given a task that I am not sure how to approach. Basically, the project is running well on say url www.asmara.com. Now, what is needed is to add a specific user group called HAY which have its own permissions. Then the users will use www.hay.com (or if to hard hay.asmara.com) to access the advanced functionality of the app. I am on python 3.6 and django 1.11 I started create a separate project but relized the existing project have stuff I want to use (solo functions and some classes) and certainly the database models. Current project looks like this: project1: members messaging shared each app has its own models, serializers and views. I want to make use of the models and possibly certain models. I am told to keep my directory separate (hence can't be inside project1, which would have make importing easy). The ideal structure I am advised to come up with is: projec1 --- project2 --- What is the easiest way to access certain functionality and models of project1 from project2, keeping in mind during deployment, they might separate from each other at all -- hence hard coding imports is not … -
