google-analytics with proxy server on apache2 and django
i have googled a lot for last few days. but i couldn't find a appropriate solution. my website uses google analysis as commonly used. but ad-blockers seems to blocking it. my code <!-- Global site tag (gtag.js) - Google Analytics --> <script async src="https://www.googletagmanager.com/gtag/js?id=G-4RPCXXXXX"></script> <script> window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'G-4RPCXXXXX'); </script> while researching i found many articles about CNAME cloacking and server proxy with node.js. can someone guide me with apache proxying or maybe a way around with django for google-analytics. or am i missing something? -

Cannot parse FormData into django backend
hope you all are doing well I have been working on a custom form that I want to send to django backend via ajax request, the only problem that I am encountering is I am wrapping the form into FormData it works well on the frontend site but on the backend it shows a querydict with some strane data in it and making it much harder to parse the data, if there can be a way to easily get the data out. Any leads or any response is much appreciated Following is my code of the javascript function that sends the data to the backend Javascript function Edit_Content(e){ var form_data=new FormData(document.querySelector("#edit-form")) let csrftoken=getCookie("csrftoken") $.ajax({ url:"{% url 'EditPost' %}", method:"post", datatype:"json", processData:false, "headers":{ "X-CSRFToken":csrftoken }, data:form_data, success:function (data){ console.log("Post or idea edited") } }) } views.py def Edit(request): print(request.POST,request.FILES) data=dict(request.POST) print(data) if data["type"] == "post": post=Post.objects.get(pk=data['id']) content=data.get("post-content",None) media=data.get("media",None) post.edit(content,media) else: idea=Idea.objects.get(pk=data["id"]) title=data.get("title",None) privacy=data.get("privacy",None) requirements=data.get("requirements",None) category=data.get("category",None) content=data.get("idea-content",None) media=data.get("media",None) idea.edit(requirements,title,privacy,category,content,media) return HttpResponse(status=200) After converting request.POST into dictionary object it it gives {'------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name': ['"type"\r\n\r\nidea\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="id"\r\n\r\n1\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="title"\r\n\r\nProgramming is great\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="privacy"\r\n\r\n public\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="requirements"\r\n\r\nnothing\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="category"\r\n\r\nFisica\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="idea-content"\r\n\r\nProgramming is not for kids\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf\r\nContent-Disposition: form-data; name="media"; filename=""\r\nContent-Type: application/octet-stream\r\n\r\n\r\n------WebKitFormBoundaryW30RtYeVz4cXnUNf--\r\n']} Which is hard to parse … -
Replacing static site with Django/Serving static files with mod_wsgi
I have an existing static website that is served via apache. I wanted to add dynamic features to that site so I created a Django app that lives in a subfolder (ie. /django-site/). I have this configured like this: WSGIDaemonProcess django_site processes=5 threads=5 user=user group=group python-home=path/to/virtualenv WSGIScriptAlias /django-site /var/www/django_site/wsgi.py <Location /django-site> WSGIProcessGroup group </Location> But now I would like to replace certain pages that were originally static pages in the root directory. But I don't want to replace all of the static pages. I know that Django recommends putting your static files in a subdirectory like /media or /static and Django configured to be the root directory but since I have a long legacy of these static pages being in the root directory and external links to these pages I don't want to change that. Is there a recommended way to replace these static pages with a dynamic ones? Here are a few ideas that I have thought of: Use ProxyPass to replace pages one at a time Redirect static pages to dynamic versions, change internal links to new dynamic version Move dynamic site to root, and use something like whitenoise to serve those files -

how to make work adsense on django web app
i'm trying to config google adsense on my django app but i can't activate my account because of my website has no content. my app is a repository to find videos or music creators which aren't famous. i have 80 creators in my database and i show them on 8 pages of my website. so that's surprised me when i've seen no content website... did somebody can tell to me if my website is maybe too empty for google adsense ? yufinder.com (my site is in french for the moment) does google has an approach to install adsense on django app ? because i don't find anything. maybe did i need to config something in my django app ? for the moment i've only had de script tag that google gave to me in my main html file but i've seen on other forums that maybe i need to install "django-ads" or something called sekizai but i haven't found a lot of informations about. if you need any informations i'll give you. thank you for helping me -

How to create "related_name" relation with parent models of "through" model (about related_name inheritance)
I have 4 models including one M2M "through" model enabling to had an index: class TargetShape(models.Model): pass class Page(models.Model): target_shapes = models.ManyToManyField(TargetShape, through='PageElement', related_name='pages') class PageElement(models.Model): target_shape = models.ForeignKey(TargetShape, related_name='page_elements') page = models.ForeignKey(Page, related_name='page_elements') index = models.PositiveIntegerField(verbose_name='Order') class WorkingSession(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='working_sessions') I defined another model Resolution that enables me to link all of them together in order to create the following related_name relations: working_session.resolutions user.resolutions target_shape.resolutions page.resolutions page_element.resolutions To have it working, I had to declare: class Resolution(models.Model): # relations that would be needed from a DRY perspective: page_element = models.ForeignKey(PageElement, related_name='resolutions') working_session = models.ForeignKey(WorkingSession, related_name='resolutions') # relations I want to exist to use user.resolutions, target_shape.resolutions, page.resolutions: user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='resolutions') target_shape = models.ForeignKey(TargetShape, related_name='resolutions') page = models.ForeignKey(Page, related_name='resolutions') However, that's not very DRY. From a DRY perspective, I should be able to declare Resolution as linking to only PageElement and WorkingSession, and deduce / inherit the relation with the parent models: class Resolution(models.Model): page_element = models.ForeignKey(PageElement, related_name='resolutions') working_session = models.ForeignKey(WorkingSession, related_name='resolutions') But in that case, how can I create the following relations: user.resolutions target_shape.resolutions page.resolutions without going through: user.working_sessions.resolutions target_shape.page_elements.resolutions page.page_elements.resolutions -
ModelForm not saving data for user profile

Problem with timezone in Django ORM, datetime value differs from the value stored in the table

However when I retrieve that row using the Django ORM, its datetime field will change: from data.models import PrecipitationContourDjango10d row = PrecipitationContourDjango10d.objects.get(id=5921) How can I solve this issue? Thanks.
