Django Model with python-docx-template
I have two Models - ReportData and Report: class ReportData(models.Model): reportname = models.CharField(max_length=25) itemname = models.CharField(max_length=50) address = models.TextField() img1 = models.ImageField(default="default.jpg" ,upload_to="report_images") img2 = models.ImageField(default="default.jpg" ,upload_to="report_images") img3 = models.ImageField(default="default.jpg" ,upload_to="report_images") date_created = models.DateTimeField(default=timezone.now) preparedby = models.ForeignKey(User, on_delete=models.CASCADE) class Report(models.Model): report = models.OnetoOneField(ReportData, on_delete=models.CASCADE,primary_key=True) document = models.FileField(upload_to='reports/') I want to perform a function using all the fields of ReportData (except preparedby,date_created) which will return a file and store in document field of Report class. The function is here: doc = DocxTemplate('--default path of template file--') context = { 'rname' : ReportData.reportname,'iname':ReportData.itemname , 'addr': ReportData.address, 'img1': InlineImage(doc, ReportData.img1.url , width=Inches(7.1)), 'img2':InlineImage(doc, ReportData.img2.url, width=Inches(4.79)), 'img3':InlineImage(doc, ReportData.img3.url, width=Inches(1.91))} doc.render(context) doc.save('destination path') I dont know what will go in destination path as I want to store it in document field of Report class. Also have no idea how to get ReportData fields in context. -

Register several DRF views in urls.py

But "URLs" mentioned in my API are corrupted, maybe because I do not know this right syntax in urls.py. I searched for and tried a lot of syntax but ... No success Thanks -

Python pickle load very slow on python 3.7 for Django nested relations, taking almost 8ms
Why is pythons pickle.load so slow for nested Django objects? I need to retreive 1800 pickled objects from cache and load them. The objects consist of a Django model instance with a 2 layers deep related object (created using 'select_related' on the queryset and then getting the required model instance). There are only a few fields (approx 5) in each layer, making the total fields about 30. Still to pickle load all 1800 objects takes almost 1.3 seconds. If I create a cached_object in the database to store it there instead of in memory, and load it from the database, it takes only 13ms for all 1800 objects, because now it doesn't need to use pickle.load, but creates the related objects 'new' from the database. Is there any particular reason that pickle.load is so slow? I was storing the objects is memory cache for performance concerns, but it only made it worse. -

My site is in production and whenever I modify my static files it doesn't reflect changes as it seems to be cached somewhere, though I can see the see changes when fresh from network tab in "inspect". My question is how can I force Django to do it automatically for me on my user's system -
Django related model not updating related object in admin
I have 2 models that look like this: models.py class Client(models.Model): deal = models.ManyToManyField('Deal', related_name="clients") class Deal(models.Model): client = models.ManyToManyField(Client, related_name="deals") Then in the admin, I have inlined the related models to make it easy to make changes regardless of the object type you have open. admin.py class ClientInline(admin.TabularInline): model = Deal.client.through class ClientAdmin(admin.ModelAdmin): inlines = [DealInline] class DealInline(admin.TabularInline): model = Client.deal.through class DealAdmin(admin.ModelAdmin): inlines = [ClientInline] However, if you add a Client to a Deal and then open the Client detail page, the corresponding deal does not appear. Is there something I'm not connecting? -
How to trigger Python script from HTML input?
I'm struggling with one part of building a website. I'm using Vue for the front end and Python for the backend. These are the steps I need to take: Take a text input in a HTML text box: <div class="search-wrapper"> <input type="text" v-model="search" placeholder="Enter Stock Ticker"/> </div> Run a python script that uses that text to run a Tweepy API search: t = tweetObj.tweetObject({{ html input here }}) tweet_string = t.get_created_at() Do a bunch of sentiment analysis (which is already done) Fill in a bunch of charts on a website (which I already have a template for) What I don't understand is whether or not I need to use Django or Flask for the Python IO. Is this necessary to take the inputs or can I get by with just simple HTTP request modules? I do understand running everything in one server, but the front end part is very new to me and I'm confused. Would appreciate some guidance on this.
