django websocket send update from database without pooling
I am using django channels with redis for backend with mysql database, I push new data to mysql database and in consumers.py i send data through websocket to client. The problem is once the new data was pushed to the database the client has to send message in order to receive the new data. therefore i am using long pulling. the client send message every 2 second and gets the new data but it is very inefficient. Is there any other way to solve this problem so the client doesn't have to send message all the time? in consumers.py: def ws_message(message): livedata = serializers.serialize("json",testLiveData.objects.all()) Group(message.content['text']).send({ "text": livedata, }) in javascript: setInterval(function() { if (socket.readyState == WebSocket.OPEN) socket.onopen(); }, 2000); i followed tutorial on channels readthedocs -
SearchQuerySet().filter(content='content') returns results, but they don't show up in search.html
I can go into my shell and type sqs = SearchQuerySet().filter(content='content') len(sqs) and I get results. I have inspected them and when I type sqs[0] sqs[0].id sqs[0].text I get coherent results. However when I use the search form on my website, I get no results. I don't even define my own SearchView. It is the default one. On the template, I have tried {% for result in page.object_list %} {% for result in object_list %} {% for result in page_obj.object_list %} and still don't get any results. And the query did run because I can put stuff inside {% if query %} so that clearly works. What do I do? Thank you. -

Matching one-or-more keywords with Django's Postgres full-text searching
If I search on a website with multiple keywords (and no quotes) -- such as for red car -- my expectation is that items containing "red car" exactly should be first, followed by items containing both keywords (but non-sequentially), followed by items containing one of the keywords. (I believe this is the default behavior in Lucene-like systems, but it's been a while since I've used them, so can't say for sure.) My hope was that the Postgres full-text searching would automatically do this, but my early tests show this is not the case: ## ASSUME: items in database: <blue car>, <green car>, <red truck> keywords = "red car" items = ForSaleItem.objects.filter(name__search=keywords) ## RESULT: items is empty/None, whereas it should have each of ## the items since one keyword matches. The hack I'm seeing is to using Django's disjunction operator, but I'm hoping there is something less-hacky. I'm also pretty sure this hack wouldn't put exact matches at the top of the list. Here's the hack: from django.db.models import Q keyword_query = Q() for keyword in keywords.split(' '): keyword_query.add(Q(name__search=keyword), Q.OR) items = ForSaleItem.objects.filter(keyword_query) Is there some settings/API that I'm missing (or something implementable on the postgres side) that gets the functionality … -

Django form in a base class
forms.py class search_form(forms.Form): options = categories.objects.all() category = forms.ModelChoiceField(options, initial={'All':'All'}, label='') search = forms.CharField(max_length=100, label='', required=False) This form is used for searching for items. And right now I have it implemented on the index page and it works as expected. The index (home) page has its own view that makes use of this form, but I have a base template (base.html) that every page on the site extends. The base template holds the menu bar and the footer of the site. I need to add the form to the base class and have it function in every template that extends it. Is there a way to do this? -
Creating random URLs in Django?
I'm creating a project where: A user submits an input into a form That data is input into the database A random URL is generated (think imgur / youtube style links) The user is redirected to that random URL The input data is display on that random URL forms.py class InputForm(forms.Form): user_input = forms.CharField(max_length=50, label="") random_url = forms.CharField(initial=uuid.uuid4().hex[:6].upper()) models.py class AddToDatabase(models.Model): user_input = models.CharField(max_length=50, unique=True) random_url = models.CharField(max_length=10, unique=True) views.py def Home(request): if request.method == 'POST': form = InputForm(request.POST) if form.is_valid(): user_input = request.POST.get('user_input', '') random_url = request.POST.get('random_url', '') data = AddToDatabase(user_input=user_input, random_url=random_url) data.save() return render(request, 'index.html', {'form':form}) else: form = InputForm() return render(request, 'index.html', {'form':form}) index.html <form action="" method="POST"> {{form}} {% csrf_token %} <input type="submit"> </form> I'm new to Python / Django, which is probably obvious. The above code allows users to submit an input which is succesfully added to the database. It also generates a 6 character UUID and adds that to the database. The problem is I don't know how to turn that UUID into a URL and redirect the user there after submitting the form. I've tried a couple of methods so far, such as adding action="{{ random_url }}" to the index.html form, as well as … -
AppConfig.ready() is Running Twice on Django Setup (Using Heroku)
I have a function that needs to run in the background on one of my web applications. I implemented a custom AppConfig as shown below: class MyAppConfig(AppConfig): run_already = False def ready(self): from .tasks import update_products if "manage.py" not in sys.argv and not self.run_already: self.run_already = True update_products() However, this command is being executed twice (the update_products() call) As stated in the documentation: In the usual initialization process, the ready method is only called once by Django. But in some corner cases, particularly in tests which are fiddling with installed applications, ready might be called more than once. In that case, either write idempotent methods, or put a flag on your AppConfig classes to prevent re-running code which should be executed exactly one time. I feel like I am following what the documentation says to do. What gives? -

Looping over JSONResponse() result from django in jquery
I am interested in getting the results of an insert operation from views.py in form a JSON. I am getting the results alright, I think. my view looks like this: added={} if request.method=='POST': #Post method initiated. try: for id in allergies: allergy=PatientAllergy(patient=patient,allergy_id=id,addedby=request.user) allergy.save() added[allergy.id]=id except BaseException as e: pass return JsonResponse(added,safe=False) The records, passed from JQUERY, added successfully to the database. What I want to get now is a JSON result in the form of {12:1, 13:2}. My firebag shows the response as: 12:1 13:2 I am not sure if this a valid JSON or not. If I do list(added), it gives instead: 0: 12 1: 13 which I don't want. The problem I am having now I want to go thru the returned items but I am getting incorrect results. I basically want to get 12:1, 13:2. $.ajax({ type: "POST", url: "/patient/addallergy/", data: postForm, dataType : "json", cache: "false", success: function (result) { alert(result.length); //gives undefined, rendering the below line meaningless if (result.length>0){ $.each(result,function(key,value){ alert(key); alert(value); }); } }, fail: function (result){ } }); -
Django models.Manager custom SQL query "more than one row returned" error
So I'm trying to get the result of the age() function on PostgreSQL from a column in the DB. The goal is to append a new virtual column with the age or time elapsed since the datetime stored the database. I tried this by creating a models.Manager in Django to add this new column: class PriorityManager(models.Manager): def get_queryset(self): time_elapsed = RawSQL('SELECT EXTRACT(EPOCH FROM age(datetime)) AS age FROM backend_post', params=(), output_field=models.IntegerField()) return super(PriorityManager, self).get_queryset().annotate(score=time_elapsed) I need a score column to help sort the objects later, and the score is based on the time elapsed. The query SELECT EXTRACT(EPOCH FROM age(datetime)) AS age FROM backend_post; works in the dbshell but when running it on Django, the following message comes up: ProgrammingError at /api/post/list/ more than one row returned by a subquery used as an expression I suspect the problem is that the query returns a whole column of elements while the models.Manager expected only one result. I believe there should be something sent as a parameter in the RawSQL query but I couldn't figure out what it is... Anyone knows what to do? Thank you very much! -

Use javascript to set action in django form
In django 1.10, I need to pass parameters from one html template back to view.py, and finally render again the same view. The problem is in setting action in the html to use javascript. This is my html template: <form method='POST' action='/res/{{link}}/{{page_id}}/{{email}}/'> <input type="hidden" name="email" value="{{email}}"> <input type="image" type='submit' src={% static "assets/images/twitter_icon.png" %}> </form> {{page_id}} in action changes as the user interacts with the web page (using a drop-down selector). The following javascript would be able to catch this: <script> function post_redirect_link() { var page_id = document.getElementById("sel1").options.selectedIndex; return '/res/{{link}}/'+page_id+'/{{email}}/' } </script> And I tried to set action dynamically as: <form method='POST' action='post_redirect_link()'> <input type="hidden" name="email" value="{{email}}"> <input type="image" type='submit' src={% static "assets/images/twitter_icon.png" %}> </form> BUT instead, I get a redirect of the type /res/correct_link/post_redirect_link()/correct_email, where "post_redirect_link()" is taken as string rather than being the value returned by the js method. Any suggestion? -

I have page class where I have saved list of component on page: class Page(object): title = None slug = None inMenu = False parent = None # place for register parent page # array of components in page # { componentName: 'carousel', htmlConent: '', images: ['slide_01.jpg', 'slude_02.jpg'] } #(from carousel model) components = [] template = Template ('index.html') I have the components now as a templateTags as inclusion_tag in django I need render page component with args. I want do something like: {% extends 'base.html' %} {% block content %} {% for component in page.components %} {% render_component component%} {% endfor %} {% endblock %} Have you tried something like that? I don't know how exactly render the templateTags from the array with args. Could someone help me with this?.
