Django - handle two form elements for the same model in one template
I am using the following UpdateView in order to alter some values in the database: class MyUpdateView(UpdateView): model = MyModel fields = ['VideoURL', 'MainDescription'] template_name = 'myapp/edit.html' This is my template: <div class="row"> <div class="col-12 col-lg-7"> <form method='post' class="card shadow-soft border p-4 mb-4"> {% csrf_token %} <h5 class="mb-4">General</h5> <div class="form-group"> <label for="MainDescription">Title</label> {{form.MainDescription|add_class:"form-control shadow-soft"}} </div> <div class="row"> <div class="col"> <button class="btn btn-primary btn-dark mt-2 animate-up-2" type="submit">Update</button> </div> </div> </form> </div> <div class="col-12 col-lg-5"> <form method='post' class="card shadow-soft border p-4 mb-4"> {% csrf_token %} <div class="form-group"> <label for="VideoURL">Video URL:</label> {{form.VideoURL|add_class:"form-control shadow-soft"}} </div> <div class="row"> <div class="col"> <button class="btn btn-primary btn-dark mt-2 animate-up-2 text-right" type="submit">Update</button> </div> </div> </form> </div> </div> However, I am facing some difficulties doing so because although both fields belongs to the same model, I cannot update any of the information. What I have noticed though is that if I place the both fields under the same HTML form, it works: <div class="col-12 col-lg-5"> <form method='post' class="card shadow-soft border p-4 mb-4"> {% csrf_token %} <div class="form-group"> <label for="VideoURL">Video URL:</label> {{form.VideoURL|add_class:"form-control shadow-soft"}} </div> <div class="form-group"> <label for="MainDescription">Main Description:</label> {{form.MainDescription|add_class:"form-control shadow-soft"}} </div> <div class="row"> <div class="col"> <button class="btn btn-primary btn-dark mt-2 animate-up-2 text-right" type="submit">Update</button> </div> </div> </form> </div> What am I … -
Issue with .pyc files on remote server
I had a Django project in which I had a file named itemA.py. Then I deleted that file and instead created a foldern with an identical name in which I placed files. So the new structure looked something like this: itemA itemB.py itemC.py ... Before that change, when itemA was a file, it contained a definition for a serializer which was imported elsewhere. So after the change, when I ran the project on my local PC, I ran into an error saying: ImportError: No module named 'rest_main.serializers.sms'; 'rest_main.serializers' is not a package On my local PC, I fixed the issue instantly removing the itemA.pyc file. But when I pushed the changes to the remote server, the same trick did not help. I also ran the find . -name "*.pyc" -exec rm -f {} \; command. But still no success...In bitbucket, all the pyc files are under gitignore... -
How can I keep javascript file paths the same when changing pages?
I've got a few scripts on my base template and when I change the page, Django affixes the script source path to the end of the url, so for example, the main page url is just 127.0.0.1 and the ajax url is "messaging/check_new" so on the main page the full ajax url is 127.0.0.1/messaging/check_new/?user=1 which works but when I go to, for example, account management. The ajax url changes to 127.0.0.1/acc_manage/manage_account/messaging/check_new/?user=1 which is not where the script is. Do I have to put the script in all of my apps or is there a way I can force it to look in the base directory static folder like you would when trying to access an image? example being the image location is project_level/folder/image and you have to get it from inside of a different app so you would have to do something like <img class="picture" src="{{BASE_DIR}}/{{ post.picture.url }}" width=250px height=300px/> How can I do that but with a script? When I try to prefix the script src with {{BASE_DIR}} it just shows an this url in the error (shown below)127.0.0.1//static/js/msg_num/js. Also when I try to use <script src="{{BASE_DIR}}/static/js/msg_num.js/"></script> it gives me the error below. Console Error for script src "{{BASE_DIR}}/static/js/msg_num.js": … -

CrawlerRunner() not going through pipeline file of scrapy
I am trying to call scrapy spider from Django Views.py file.The spider does gets invoked but its output is shown in command prompt and is not saved in Django models to render it onto the page.I checked running spider separately to verify that scrapy and Django are connected and it does work correctly,but when automated using CrawlerRunner() script it doesn't.So some component is missing in CrawlerRunner() implementation from Django views.py file. Below is the Django Views.py file which calls the spider: @csrf_exempt @require_http_methods(['POST', 'GET']) def scrape(request): import sys from newscrawler.spiders import news_spider from newscrawler.pipelines import NewscrawlerPipeline from scrapy import signals from twisted.internet import reactor from scrapy.crawler import Crawler,CrawlerRunner from scrapy.settings import Settings from scrapy.utils.project import get_project_settings from scrapy.utils.log import configure_logging from crochet import setup setup() configure_logging() runner= CrawlerRunner(get_project_settings()) d=runner.crawl(news_spider.NewsSpider) return redirect("../getnews/") My spider does the work of crawling news website and saves Url,Image and Title of top news.But output is that rather than saving this three fields in models.py file it is printing in cmd.

Django: Override model methods from abstract base class models
I am trying to use an abstract base class model in Django to avoid writing some duplicate code and encountering some unexpected behavior. Here is simplified version of my abstract base class: class AbstractDocument(models.Model): notes = models.CharField(max_length=255) document = models.FileField(upload_to=document_file_path) def document_file_path(instance, filename): pass class Meta: abtract = True I need to define the method document_file_path or the code generates error. I want to define different behavior in the subclasses for the document_file_path. Below is an example: class BookDocument(AbstractDocument): book = models.ForeignKey(Book, on_delete=models.CASCADE) def document_file_path(instance, filename): return f'books/{filename}' It does not appear that the child method is overriding the parent method because I get an error that document_file_path returned NoneType when I run the code above. I tried making the method in AbstractDocument return an actual path, but the child method doesn't override the parent in that scenario either. Is there some reason why what I'm trying to do is not possible? Is there something I'm missing in the implementation? Is there another or better way to accomplish this? Thanks in advance for your help! -

Redirect logged in users from register view
I want logged in user redirect to index when they attempt to go to the register form. I manage to do to that, but I can't validate the register form when the a user who is not logged in complete it. I have a custom view for signup: class SignupView(UserPassesTestMixin, FormView): template_name = 'main/auth/register.html' form_class = forms.UserCreationForm def test_func(self): self.request.user.is_authenticated def handle_no_permission(self): if self.request.user.is_authenticated: return redirect('main:index') return self.get(self.request) def get_success_url(self): redirect_to = self.request.GET.get`enter code here`('next', 'main:index') return redirect_to def form_valid(self, form): response = super().form_valid(form) form.save() email = form.cleaned_data.get('email') first_name = form.cleaned_data.get('first_name') raw_password = form.cleaned_data.get('password1') logger.info('Nuevo registro para email=%s a través de SignupView', email) user = authenticate(email=email, password=raw_password) login(self.request, user) form.send_mail() return response methods test_func(self) and handle_no_permission(self) are used to test if the user is authenticated but I think the problem is in return self.get(self.request) I use it to load the form but when I submit the form with correct data, it doesn't POST it to validate it, just reload it again. I suppose I have to call form_valid but I can't figure out how. Any help would be appreciated!! Regards -

django shapeshifter - submitting forms with foreign keys
I have two forms I want to submit as one, Form A and Form B. These are modelforms - Form B has a foreign key into Form A. I'm using django-shapeshifter to construct the form, with the MultiModelFieldView. I have the form rendering OK - but when I try to submit the POST request fails because of the key NOT NULL constraint - in the traceback can see the INSERT INTO modela_modelb contains NONE for both rv_id and modelAid. I have tried adding these to the form as hidden fields, but I don't think this is correct. django-shapeshifter docs: https://pypi.org/project/django-shapeshifter/ example with forms being created manually: django: How to make one form from multiple models containing foreignkeys - I believe this example doesn't apply since shapeshifter actually submits the forms individually. models.py class ModelBdata(models.Model): rv_id = models.IntegerField(primary_key=True) modelAid = models.ForeignKey(ModelA, on_delete=models.CASCADE) formFieldB = models.CharField( max_length=300, blank=True, null=True, verbose_name='form_field') class ModelA(models.Model): modelAid = models.AutoField(primary_key=True) formfieldA = models.CharField( max_length=100, verbose_name='Model A Name', unique=True) forms.py class ModelAForm(ModelForm): class Meta: model = ModelA exclude = ('ModelA_family_id','created_by','ModelAid',) def __init__(self, *args, **kwargs): super(ModelAForm, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.form_tag = False def clean(self, **kwargs): data = super(ModelAForm, self).clean(**kwargs) # If this the ModelA is not saving … -

Wagtail: Pass a vanilla Django model instance to widget
I have a model based on Django's models.Model which I register via ModelAdmin in the admin view. One of my fields has a custom widget assigned to it. # models.py panels = [ # ... CustomFieldPanel('geom', widget=LeafletWidgetWithMedia) # ... ] I need the widgets context to be aware of the model instance. Here is what I tried so far, based on an answered question I posted before. I updated the FieldPanel to pass the instance to the widget. class CustomFieldPanel(FieldPanel): def on_instance_bound(self): self.widget = LeafletWidgetWithMedia(page_instance=self.instance) Then I updated the __init__ and the get_context functions of the Widget: class LeafletWidgetWithMedia(LeafletWidget): include_media = True template_name = "admin/widget.html" def __init__(self, attrs=None, **kwargs): print("Kwargs: " + str(kwargs)) self.page_instance = kwargs.pop("page_instance", None) print("Instance: " + str(type(self.page_instance))) # ... def get_context(self, name, value, attrs): value = None if value in validators.EMPTY_VALUES else value context = super(LeafletWidget, self).get_context(name, value, attrs) context["page_instance"] = self.page_instance context.update(self._get_attrs(name, attrs)) print("Page instance in context: " + str(self.page_instance)) return context This approach works flawless if my model is based on Wagtails Page model but here the context won't get updated. The print statements in the __init__ show the instance gets passed to the widget: # Kwargs: {'page_instance': <MyModel: 7>} # Instance: <class 'register.models.MyModel'> …
