Making a table within the Templates folder in Django
I am trying to create a table in Django using a template file I named law.html with data formated in a dataframe from a function I created to scrape information from a public web page. I am trying to use a for loop to iterate through the data but the desired output cannot be achieved for some reason. So far I have a DataFrame called newlaw that is called by the function all_data. The dataframe newlaw is a list of solicitors names and offices. I then imported all_data into my views.py folder and gave it the dictionary 'all_data'. Within my law.html folder I am attempting to create a table using a for loop so that I can have each piece of data in a single cell. The code in my views.py ```def law_view(request, *args, **kwargs): all_data = combine_data() return render(request, "law.html", {'all_data': all_data})``` The code in my law.html ```<table class="table table-striped"> <thead> <tr> <th>Solicitor_Names</th> <th>Offices</th> </tr> </thead> <tbody> {%for solicitor in all_data%} <tr> <td>{{ solicitor }}</td> </tr> {% ednfor %} </tbody> </table>``` This code only prints out the column names. My desired output would look like Solicitor_Name Office John Marston Ernst & Young Amy Smith Kingston Smith .... .... -
Django, Filter a list with AJAX
I am trying to build filter that filters through a list when clicked (option values). Currently the list works using Django's logic, but I need to change it to AJAX (to get more familiar with it). I know that there are other questions similar to this, but I just can't seem to get a hang of it. views.py def gps(request): gps = GoodPractice.objects.all() progr = Programme.objects.all() progr_list = request.GET.getlist("progr") gps = GoodPractice.objects.filter(id__in=ProgrammeList.objects.filter(programme__in=progr_selected).values("goodpractice")).values("name", "country", "programme_type", "what", "id") context = { "active": "gps", "gps": gps, "progr": progr, "progr_list": progr_list, "progr_selected": progr_selected, } return render(request, "gps.html", context=context) This is my script <script> var count = 0; $("#btn-primary").click(function(){ fetchDataAndDisplay(); }); function fetchDataAndDisplay(){ $.ajax({ url:"{% url 'gps/' %}", method:"GET" }).done(function(data){ var start = count > 0 ? 5 * count : count; var end = start + 5; var str = ''; for(var i=start; i<end; i++){ str += '<div class="item-details">' + 'User Id is = ' + data[i].userId + '<br />' + 'Id is= ' + data[i].id + '<br />' + 'Title is = ' + data[i].title + '<br />' + '</div>'; } if(start == data.length){ count = 0; $(".display-data").empty(); $(".display-data").append("List Traversed.

django channels with redis: messages created before websocket connection established are lost
I have managed to get django sending messages to a browser websocket client using channels. But I don't understand it very well. Messages my Celery background task creates before the websocket handshake from the browser do not get shown. messages are sent with async_to_sync(channel_layer.group_send)(str(job.id),..) Django v 2.1.7. The channel layer uses redis so group_send is from channels_redis and the first argument is the group id. I would like a client connecting with the job.id to get all messages ever sent to that group. Does this make sense? -

Cannot call ModelAdmin.change_view(), ManagementForm data is missing
I am programming a website that displays events. Each occurrence of an event is its own object. Since many of the events are repetitive and it is tedious to re-enter everything and just change the date, I added an occurrence generator, such that the user can set name, location, and time, and then choose a bunch of dates, for which occurrences can be generated with those properties. I have integrated a form for the occurrence generator into the change view of the Event's admin page. I even managed to get it working, even though I encountered a lot of pesty type errors and type-related crashes. (I really wish Django had type hints.) However, in case the submitted occurrence generator form is invalid, Django does not correctly display the change view. It crashes with a validation error, ['ManagementForm data is missing or has been tampered with']. I tried looking through the trace, but I couldn't figure out what is causing it. I am simply passing the invalid form as extra_context, in order for the page to show the errors to the user. admin.py class EventAdmin(admin.ModelAdmin): inlines = [OccurrenceInline] change_form_template = "admin/event_change_form.html" def change_view(self, request, object_id, form_url="", extra_context={}): extra_context["generator_form"] = extra_context.get( "generator_form", … -

Function in django views run 2 times without reason
I have problem because I can not find the reason why my function in django views sometimes runs two times. When I go to url, which call function create_db in djnago view, function read json files from directory, parse it and write the data in the database. Most of the time it works perfectly, but sometimes for no reason it runs two times and write the same data in the data base. Does anyone know what can be the reason why code is sometimes done twice?

Digital Freight Marketplace
I am trying to create a model in which manufacturers can post a shipment which needs to be transported and transporter can post that his truck is going from point A to point B. If the Origin, Destination, and load(to be transported and truck capacity) matches then both of them are notified a match. I have tried researching on automatic matching but the closest I come to is the Hungarian Algorithm that solves the assignment problem, but I am not so sure if it's the right direction or not. In the model, I have already created input forms for both sections i.e. manufacturers and transporters and the data is saved in a Database. I am thinking of applying a trigger function which rechecks for the best match every time when a new entry comes in Database Here is the Data from both input forms: Manufacturer M_ID From To M_Type T_Type T_Length T_Weight #Trucks Loading_Time 1025 A B Boxes Open 12-Tyre 22 3 27-March-2019 6:00PM 1029 C D Cylinders Trailer HIGH 23 2 28-March-2019 6:00PM 1989 G H Scrap Open 14-Tyre 25 5 26-March-2019 9:00PM Transporter T_ID From To T_Type T_Length T_Weight #Trucks Price 6569 A B Open 12-Tyre 22 5 … -
