django failed to load static image
I have my django app hosted on pythonanywhere. I am using weasyprint to generate a pdf and there is an image to be shown in my pdf. The error in the error log is "Failed to load image at /static/images/logo.png". When I try to open the same path as url, it shows me the image in the browser. Which means it is getting the path right but something else is wrong. I have my static directory placed outside the app. And this path is added to the settings file. My folder structure: my_app static |__ css |__ images |__ logo.png |__ js templates |__ my_app |__ pdf.html settings.py: STATIC_DIR = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' STATICFILES_DIRS =[ STATIC_DIR, ] pdf.html: {% load static %} <td><img class="my_logo" src="{% static 'images/logo.png' %}" alt="Temporarily Unavailable"></td> -

Define weight for completion suggest field in elasticsearch-dsl
Using Elastic Search 5.2.x and elasticseach-dsl for bulk index creation in my Django app, I am trying to implement a completion suggest field like so: def indexing(self): obj = SchoolIndex( meta = {'id': self.pk}, name = self.name, name_suggest = self.name ) obj.save(index="school_index") return obj.to_dict(include_meta=True) Now, I need to define some weights for the suggest field-name_suggest, so that the suggestions get scored during querying, but I am not able to figure out elasticsearch-dsl specific syntax to do the same in the function above. I tried doing this, but it didn't work : name_suggest = {'input':self.name,'weight':100} Essentially, I am trying to implement in Django, what the docs show here : https://www.elastic.co/guide/en/elasticsearch/reference/5.6/search-suggesters-completion.html#indexing I am new to Elastisearch, please advise if I am assigning the weight at the right place in code and the syntax to do it in Django.

How to fix a Scrapy spider that, when executed as a script inside a Django package, won't go deeper into callbacks?
So basically, I'm trying to make a Django app where users could scrape information from all posts from all groups an FB user is in. I was planning to execute a scrapy spider from a view, maybe when a button is clicked or so. If you'd like to see, `(It said that I have to have a code before a pastebin link, sorry im new to SO)` https://pastebin.com/X1PqsFHu (note that the spider is not really that great, but it IS working (to some extent) I have plans to edit the code, instead of yielding information, I'd just import Models from my Django app and save it. so I saved it into a file called scraper.py and placed it inside the app package in the Django app. Now, to execute the spider, I just followed the Scrapy doc. I used the Crawler from scrapy to a module: import scrapy from scrapy.crawler import CrawlerProcess from scraper import GroupPostsSpider def scrape(inp_email, inp_pass): spider = GroupPostsSpider(email=inp_email, password=inp_pass) process = CrawlerProcess({ 'USER_AGENT': 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)', 'ROBOTSTXT_OBEY': False, }) process.crawl(spider) process.start() Now, when I run the spider from a scrapy project, it actually executes from start to end, with the proper logs … -
Creating a custom import statement which accepts variables, used to import django models
I'm creating a simple script used to generate fixture data for a given django model. I cannot figure out how to create an import statement which accepts user input, to allow me to perform the actual logic on the selected model. I've tried various combinations of imp, importlib.util.spec_from_file_location, importlib.import_module, __import__, Create an import statement using variable "interpolation" The closest I've gotten is: def import_function(app, model): exec(f"from {app}.models import {model}") exec(f"print({model}.objects.all())") #This works. import_function("home", "Person") My thinking is: I create a module called 'fixture.py'. Within that module is a custom import function. I import the module into the environment created by python manage.py shell so as to obviate the need for modifying the PATH. Then, I call the function using fixture.import_function(app, model). I've managed to generate the fixture data this way, but only when I'm hardcoding the import statement, i.e. from home.models import Person. #fixture generating logic. -

I'm working through the official Django tutorial, using Django 1.8.7 for a certain reason. https://docs.djangoproject.com/en/1.8/intro/tutorial02/ I got stuck in part 2 near the end, where I should learn how to use edited template files from the Django source files to make changes of the admin site. I found the first template file in the described directory: django/contrib/admin/templates/admin/base_site.html I copied and changed it as described, and I was happy it worked. But now the issue I'm having, is this: I'm supposed to find another template file called site_header with the described package/directory django.contrib.admin.AdminSite.site_header, but I can't find it in the library of my project, which is runnig on a virtual env. -

custom field validation error does not show field name
I want to implement a change password endpoint, I have this view: def update(self, request): user_data = {} classname = __class__.__name__ function = 'update' try: user = request.user current = request.data['current'] password = request.data['password'] confirm = request.data['confirm'] serializer = serializers.ChangePasswordSerializer(user, data=request.data) if serializer.is_valid(): serializer.save(updated_by=request.user.username, updated_date=timezone.now()) logger(request, msg=_("Added Successfully"), level="normal", classname=classname, function=function, user_data=user_data, status=status.HTTP_205_RESET_CONTENT) return Response({"message": _("Added Successfully")}, status=status.HTTP_205_RESET_CONTENT) logger(request, msg=serializer.errors, level="error", classname=classname, function=function, user_data=user_data, status=status.HTTP_422_UNPROCESSABLE_ENTITY) return Response({'errors': serializer.errors}, status=status.HTTP_422_UNPROCESSABLE_ENTITY) except Exception as ValidationError: return Response({"errors": _("Current password is not correct")}, status=status.HTTP_422_UNPROCESSABLE_ENTITY) except Exception as e: elogger(msg=e.args) return Response({"message": _("status500")}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) and this is my serializer: class ChangePasswordSerializer(DynamicFieldsModelSerializer): current = serializers.CharField() confirm = serializers.CharField() def validate(self, data): if data['current'] == data['password']: raise serializers.ValidationError("Password and Current password should not be the same") if data['confirm'] != data['password']: raise serializers.ValidationError("Password and Confirm password did not match") return data class Meta: model = models.User fields = ('password', 'current', 'confirm') validators = [] def update(self, instance, validated_data): if not instance.check_password(validated_data.get('current')): raise serializers.ValidationError("Current password is not correct") else: instance.set_password(validated_data['password']) instance.save() return instance my first problem is that I get this validation error: { "errors": { "non_field_errors": [ "Password and Current password should not be the same" ] } } I want to have my field name instead …
