Form HTML, GET method. URL with multiple keywords
I'm building a search page that allows doing a search from 1-4 keywords that through the get method sends to the results page.(eg. for those keywords: one, two tree --> website.com/search/q=one+two+tree) Right now when I add more keywords and press search it sends to the URL using just the keyword in the text input. I tried to create a string joining the keywords with the "+" but sitll doesn't work. The following code is what I have tried. This is a django webapp and in the form.py there is one charfield with an id tag named "add_keyword". The function that doesn't work is send_keywords() <body> <link rel="stylesheet" href="style.css"> <script type="text/javascript"> var keywords_array = [] function getInputValue() { if (keywords_array.length<4){ var ul = document.getElementById("keywords"); var li = document.createElement("li"); var inputVal = document.querySelector("#add_keyword").value; li.appendChild(document.createTextNode(inputVal)); ul.appendChild(li); keywords_array.push(inputVal); } if (keywords_array.length==4){ console.log("You've added the max number of keywords") } } function send_keywords() { query = keywords_array.join("+") window.location.href= window.location.href+"/search/q="+query return query } </script> <h1>Dulcis in Fundo</h1> <h2>Let's coock something, what do you have left?</h2> {% block content %} <form class="" action="/search/" method="GET"> <ul id="keywords"> </ul> {{ form }} <button type="button" onclick="getInputValue();" name="button">add</button> <button type="submit" onclick="send_keywords()">Search</button> </form> {% endblock %} </body> -
Support for partial file downloads using HTTP / REST
I have a client/server architecture in which the client needs to periodically download large files from the server. Let's say the client downloads 9Gb of a 10Gb file and then temporarily loses internet connection. When the client regains connection, I would like the client to be able to download the remaining 1Gb of the file rather than need to re-download everything from scratch. Is there any platform, libraries, frameworks, etc. which handles this? If not, does anyone have any ideas on how to best approach this problem? Server/Client Technologies Server - Python / Django / Django REST Framework Client - Android / iOS / c++ Current Server Code def post(self, request): try: user = request.user file = MyFile.objects.filter(user_id=user) response = FileResponse(open(file.path, 'rb')) return response except Exception as e: return Response({'status': str(e)}, content_type="application/json") -

How to temporarily disable a token in Django REST Framework
I have created a Django app using REST Framework and created user and token for authentication using the following commands: python manage.py createsuperuser --username Alex --email Alex@example.com python manage.py drf_create_token Alex I can view newly created user (Alex) and its token in Django admin panel and have no problem with authentication but I want to be able to sometimes temporarily disable a token (say for Alex for example) so that he could not authenticate. Is there anyway to disable token? Note: recreating the token is not an option because upon executing python manage.py drf_create_token Alex a completely new token will be generated. -

Loop through items before rendering pdf and populating table using pdfkit and Django
I'm trying to export all of my users and data related to them in a rendered pdf. I'm struggling to loop over all my users and creating new table rows for each user.

URL not found for updateview with polymorphic models and forms in Django
I am trying to display all the models that are related to another model in a modal box when a user clicks on a button. However, the Update view is not working how I want it to work. I am getting a Not Found for the URL pattern related to the class based view (Model Object UpdateView) instead of 200 OK I tried several approaches, but below is the latest one. When I do a print out of the get_queryset (that I have override), I get the objects. I tried to print the context['formset'], but it seems like the code didn't reach that far.

DjangoREST vs ExpressJS , which 1 should I choose to build REST API?
I want to build REST API (or GraphQL API) which I want to connect with Angular (2+) to build some nice web application. Which framework should I choose to get started with and why?

I also have experience with django as well as some JavaScript front-end frameworks like Angular. So, it wouldn't be that difficult to get started with nodejs or either of them. Which of then is easier and better? -
How to properly link SCSS using PythonAnywhere?
I am currently working on revamping my portfolio, so I decided to switch fully to SCSS instead of CSS. Now even before when I commit from PyCharm I always need to edit it a little bit, to make it work in PythonAnywhere. The explanation: This is the code I use to make it work in PyCharm TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'static') STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) MEDIA_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_URL = '/media/' Now to make this work in PythonAnywhere I have to edit above code to this: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['portfolio/templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] MEDIA_ROOT = u'/home/Gromis/portfolio/media' MEDIA_URL = '/media/' STATIC_ROOT = u'/home/Gromis/portfolio/static' STATIC_URL = '/static/' I think that is the issue why I can't properly link SCSS file, is because of the wrong path in settings.py . I get this error now while loading the website: Unable to locate file scss/style.scss while rendering tag 'sass_src' in template project_index.html Of course, the same code works perfectly in PyCharm, so … -

Django CMS CSS trouble?
Im trying to style a plugin in my Django-CMS project ( django 1.11, CMS 3.6.0 ). Im trying to add my class to my plugin html, like this : <div class="question"> <h1 class="question-title">{{ instance.poll.question }}</h1> <form action="{% url 'polls:vote' instance.poll.id %}" method="post"> {% csrf_token %} <div class="form-group"> {% for choice in instance.poll.choice_set.all %} <div class="radio"> <label> <input type="radio" name="choice" value="{{ choice.id }}"> {{ choice.choice_text }} </label> </div> {% endfor %} </div> <input type="submit" value="Vote" /> </form> </div> Then I go into my css, and try to apply some styles to the plugin, but nothing happens. When I inspect my div which should have a class of "question" in the browser, there is no class even though I specified it in my html. Why is that ? When I do something like : body { width: 1060px; margin: 10px auto; } It applies the styles correctly. Anybody knows what is happening here ? Where are my custom classes from the html ? I was trying to find a guide on Django-CMS and styling, but Im not having much luck. Thank you guys ! -
Passing data from external python script in django to swift
Trying to create a swift request where an external python script is run in Django and returns data to the user. I just cant wrap my head around on what best practices there are or on how to do this. Any help would be appreciated. Python script returns print(output) Djano views.py def post(self, request, *args, **kwargs): self.create(request, *args, **kwargs) inp = request.FILES.get('image').name out = run([sys.executable,'//Users//macbookpro//TestAPI//venv//Test_Script.py',inp],shell=False,stdout=PIPE, text= True) print(out.stdout) return Response ({"output": str(out)}) Swift to: REST_UPLOAD_API_URL, headers: headers, encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) print(stdout) What would be the best way to pass data from the Python script and back to the user? Do i need to create a JSON response in Django and afterwards Decode it in Swift? If so, how would that work? If not, then how can you decode the "stdout" response in Swift which I'm currently receiving. Results so far: print(out.stdout) gives me the desired text response within Django DebugPrint(response) = Returns desires text --> stdout='MyDesiredText\n')"; print(stdout) in Swift gives me = 0x000000010a45d1a8 -

How to save foreign from html form (select)?
I can not save the appropriate value for ForeignKey from the form. The value of ForeignKey is always written to the database, with id = 1. in html form the values from my model, which is in the database, are output to the select.
