Font awesome not showing icons
I'm deploying a django application that collects the static files from a S3 bucket. Yesterday I managed to fix this problem before because there was a CORS problem and icons were displayed properly. Today they appear as blank squares again even if I haven't changed anything (I don't receive any problems in the chrome console so it can't be the cors problem). If I use the font awesome CDN it works fine but I'd like to know what can be the problem and keep using my static file. Many thanks. -

Which is Better for calling a stored procedure-Raw SQL query using object manager or cursor object in Django?

Django rest Framework : Serializers and business logic
Model "Page" with fields : pagename, pagenumber Model "Para" with fields : paraname , paranumber, pagenumber[this is a foreign key] Post API :/para Post data : { pagename:Page1, pagenumber:1, paras:[ { paraname:para1, paranumber:1 }, { paraname:para2, paranumber:2 }, { paraname:para3, paranumber:3 } ] } The intent of the post API is to create multiple paras in one bulk call after creating the page. I have two serialiazer : CreatePageSerializer(ModelSerializer) which expects the page name and page number CreateParaSerializer(ModelSerialzer) which expects the para name,the para number and the page number. I am doubtful however how to process the complete request in one go. Keeping the business logic in the views , i.e calling the CreatePageSerializer first and then CreateParaSerializer, does not seem right. I am thinking of creating another serializer : CreateBulkSerializer(BaseSerialzer) which would then call the CreatePageSerializer and CreateParaSerializer. However the questions are: How will I send the data to the CreateBulkSerializer (set as serializer context?) which would be be default function called? Would I need to override the init and then handle the logic there ? Or is there any other approach that I am missing here? -
django : render multiple templates in get_data(request)
How to render data on to two templates in get_data()? Generally, def get_data(request): data = Model.objects.order_by('id') return render(request, 'template.html', {'data':data}) . {{for x in data}} {{x.model_field}} {{end for}} is used to render the stored data from the db into the html file, but how to render the same data into both 'template.html' and 'template_1.html'. There's no way to pass the templates as a list to my knowledge as read from django_docs. Is there any alternate method to it? -
Django filter from multiple fields with empty input
I am new to Django and I am right now trying to deal with the issue of filtering based on specific field. React.js is used for the front-end and Django is used as RESTful APIs. For the front-end, users are allowed to choose to either search based on number or name. The info has been successfully collected. The following code just for better understanding and is incomplete. <input type="text" /><label>Search by number</label> <input type="text" /><label>Search by name</label> For the backend, response should filter the queryset based on input information, which is either number or name. However, when I went through the document, I noticed that for filtering, all the filtering fields should be provided. Entry.objects.filter(number=123, name="abc") How can I do the filter based on the given info from the front-end, for example, if user chooses to search by name that Django does: Entry.objects.filter(number=123) while if user chooses to search by name, then Django does: Entry.objects.filter(name="abc") I understand that I can actually create two different APIs endpoints, so the number and name won't interfere each other. However, if there are more filter fields, then it is definitely inefficient to write every single API based on each field. Anyone can help me ... -

How do you use Django in Python to make html/css framework much faster?
I've done very tedious task for html and css alone to make pH barometer, but I found out Python Django has a function to do this within a fraction of seconds. How do you do that? <!DOCTYPE html> <html> <head> <title>Color</title> <style type="text/css"> body { background-color: silver; color: white; padding: 20px; font-family: Arial, Verdana, sans-serif;} h1 { background-color: #fffffff; background-color: hsla(0,100%,100%,0.5); color: #64645A; padding: inherit;} p { padding: 5px; margin: 0px;} p.zero{ background-color: rgb(238,62,128);} p.one { background-color: rgb(244,90,139);} p.two { background-color: rgb(243,106,152);} p.three { background-color: rgb(244,123,166);} p.four { background-color: rgb(245,140,178);} p.five { background-color: rgb(245,159,192);} p.six { background-color: rgb(245,176,204);} p.seven { background-color: rgb(0,187,136);} p.eight { background-color: rgb(140,202,242);} p.nine { background-color: rgb(114,193,240);} p.ten { background-color: rgb(84,182,237);} p.eleven { background-color: rgb(48,170,233);} p.thirteen { background-color: rgb(0,160,230);} p.fourteen { background-color: rgb(0,136,221);} </style> </head> <body> <h1>pH Scale</h1> <p class="fourteen">14.0 VERY ALKALINE</p> From this source What is the difference between Django and Html? What function or setting do I have to find in Django to make any framework of html/css within a fraction of seconds since html and css alone to make such framework is hugely tedious task?
