Writing multiple page pdf from html template using weasy print and django
Hi am generating PDF's from html template containing a table which number of rows vary, problem is when the rows are in excess of certain number(12) the rest of the rows plus the footer are pushed further below and don't appear in the generated pdf.How can I make it dynamic so that extra info is pushed to new page each having atleast a certain number of rows, or is there a way weasy print to move data to another page if the current is full So far I have page breaks on the template but it has worked. {% for record in data %} <tr> <td> {{ record.id}}</td> <td> {{ record.date}}</td> </tr> {% if forloop.counter|divisibleby:12 %} <div style="page-break-after: always;"></div> div style="page-break-before: always;"></div> {% endif %} {% endfor %} -
How to allow page refresh/redirect after Ajax POST submission (of Django form)
I'm a client-side newbie learning the ropes, and need to clarify Ajax concepts. e.preventDefault(); is a typical method of preventing form submission (page refresh) in JS. One use case where the above is handy is Ajax-based form submission. Sample code is: function overwrite_default_submit(e) { // block the default behavior e.preventDefault(); // create and populate the form with data var form_data = new FormData(); form_data.append("reply", text_field.value); // send the form via AJAX var xhr = new XMLHttpRequest(); xhr.open('POST', e.target.action); xhr.setRequestHeader("X-CSRFToken", get_cookie('csrftoken')); xhr.send(form_data); } I have two questions: 1) Imagine the POST request is being sent to a function that ends with a redirect to a different URL. For example, I use Django to develop web applications; a typical Django view may end up with return redirect("home") where home is the home page of the said app. In such a scenario, how does preventDefault() prevent the redirect statement in server-side code from executing? I'm trying to understand the exact mechanics behind it. 2) What if one wanted page refresh (or redirect) to proceed normally after an Ajax POST request? What tweaks need to be made? Would love to see an illustrative example to clarify my concepts. I'm well-versed in Django (Python) so … -

Context variables not resolving under template inheritance using global javascript vars
I'm trying to send context variables into my template to be used with javascript. The JS file lives apart from the template, so I'm attempting to declare the global JS vars in the base template first, then use them in the JS file. One of the variables works(myuser), but the other does not(notifications). What's going on? views.py: class NotificationsView(View): def get(self, request, *args, **kwargs): profile = Profile.objects.get(user__username=self.request.user) notifs = profile.notifications.unread() return render(request, 'base.html', {'notifs': notifs}) base.html: ... {% include "landing/notifications.html" %} <script src="{% static 'js/notify.js' %}" type="text/javascript"></script> {% register_notify_callbacks callbacks='fill_notification_list, fill_notification_badge' %} landing/notifications.html: <script type="text/javascript"> var myuser = '{{request.user}}'; var notifications = '{{notifs}}'; </script> notify.js: ... return '<li><a href="/">' + myuser + notifications + '</a></li>'; }).join('') } } -

django RequestFactory loses url kwargs
I am trying to switch from using Django Test Client to RequestFactory to speed up my tests. However, requests generated by RequestFactory do not supply proper kwargs to views. Example: this is my view class SomeView(View): def get(self, request, *args, **kwargs): return JsonResponse({'your kwargs': str(kwargs)}) with urlconf url(r'^some_view/(?P<some_kwarg>[\-0-9a-fA-F]+)/$', views.SomeView.as_view(), name='some_view'), and two tests: def test_different_kwargs(): c = Client() response = c.get( reverse('bots:some_view', kwargs={'some_kwarg': '12345'}), ) print('\n\nResponse for TestClient: ', response.content.decode()) rf = RequestFactory() request = rf.get( reverse('bots:some_view', kwargs={'some_kwarg': '12345'}), ) response = SomeView.as_view()(request) print('\n\nResponse for RequestFactory: ', response.content.decode()) What they produce is: Response for TestClient: {"your kwargs": "{'some_kwarg': '12345'}"} Response for RequestFactory: {"your kwargs": "{}"} So, what's the point of RequestFactory if it loses url kwargs? Or is there a way to put them into the view somehow? -
Is there a way that a Django template include is not silent if it fails for developement
I would like to have the possibility that include templates are not silent when they fail Let me explain.. We have a main template A. We have a template to include B that contains an error. When we include template B, this one will not be displayed because it contains an error even if the template_debug = True, and it looks fine. The fact that fails are silent is convenient for a production environment. However, often on the environment of development this can pose problem insofar we do not see that there is a problem since it does not appear. Even if we can often see the error in the console. Also for the debug it is relatively painful as sometimes we do not know where the error comes from. So my question is: would there be a solution (ex: custom template tag include_noisy, or middleware) for the template include not silentious on local machines, and thus correctly display errors as in a normal template? For sure, the silent is still always present when the template_debug = False Thanks in advance -
Django - displaying images on the page using pyuploadcare
Python, Django, pyuploadcare, html5, jquery, The Django documentations for pyuploadcare are useful for image customization and file uploading and stuff like that, but what they don't tell you is how to display the image in the webpage. For example, i can display the URL where the image is stored, but i cannot display the image itself in the webpage i want to make this as clear as possible to the reader so I'll give another example: To build an image gallery, i would need all the images displayed on one page, i can do that using the for loops for photo in photos Photo and photos are defined in views.py {% extends 'base.html' %} {% for photo in photos %} {{ photo.caption }} {{ photo.photo }} {% endfor %} {% block content %} {% endblock %} photo.caption is an models.CharField() photo.photo is an ImageField() from from pyuploadcare.dj.models import ImageField everything is working properly but i don't know how to display the images on the webpage.

wagtail 2.0b1 admin static files issue

( also when collectstatic command runs no wagtile files are copying ) WARNINGS: ?: (wagtailadmin.W001) CSS for the Wagtail admin is missing HINT: Most likely you are running a development (non-packaged) copy of Wagtail and have not built the static assets - see http://docs.wagtail.io/en/latest/contributing/developing.html File not found: /Users/burakk/BurakWorks/Web/VIRTUAL_ENVIRONMENTS/python3.6.1/src/wagtail/wagtail/admin/static/wagtailadmin/css/normalize.css I have checked the wagtail 2.0b1 folder and there is a 'static_src' folder instead of a folder named 'static'. I have checked the previous stable version's admin folder and there is also a 'static_src' folder so that is not the problem I think? -

Render Chart from custom template in Django
I am trying to render chart (Echart) from costume template. I have a base where JS librarires included and a block where I want to show my chart. In this block there a many things and I would like to separate my charts via custom templates. According to the Echart example I have to render it.

Django form valid even if it doesn't exist in template
I have multiple forms using a single submit button in my template with prefix=name using CrispyForms. Check if a form exists or is rendered in Template. Django I have the following code in my template {% extends BASE_TEMPLATE %} {% load crispy_forms_tags %} {% block title %}<h2>New Thread</h2>{% endblock %} {% block content %} <div class="col-md-6"> <form method="post" accept-charset="utf-8">{% csrf_token %} {{ threadForm|crispy }} {{ postForm|crispy }} {% if SHOW_WIKI %} {{ wikiFrom|crispy }} {% endif %} <input type="submit" class="btn btn-primary btn-sm" value="Submit"/> </form> </div> {% endblock %} The only filed which the WikiForm renders has blank=True. What happens when I do wikiForm.is_valid() in my code is even though it hasn't been shown in template it is valid according to Django. Why does this happen? Is there a way to fix this in a way other than making the field in my wikiForm to blank=False? -

Rendering validation errors when using Ajax to POST Django form data
How does one generally go about handling validation errors when using Ajax to process POST requests of Django forms? I'm a server-side dev dabbling in a bit of pure JS to learn the ropes. I finished writing AJAX methods to handle the POST request of a Django form, but am now unsure regarding how to render validation errors. For instance, here's a simple Django form: class TextForm(forms.Form): reply = forms.CharField(widget=forms.Textarea(attrs={'cols':30,'class': 'cxl','autocomplete': 'off','autofocus': 'autofocus'})) def __init__(self,*args,**kwargs): super(TextForm, self).__init__(*args,**kwargs) self.fields['reply'].widget.attrs['id'] = 'text_field' def clean(self): data = self.cleaned_data reply = data["reply"].strip() if not reply: raise forms.ValidationError('Write something') elif len(reply) > 1500: raise forms.ValidationError("Can't exceed 1500 chars") return reply And here's how the Ajax request works: function overwrite_default_submit(e) { // block the default behavior e.preventDefault(); // create and populate the form with data var form_data = new FormData(); form_data.append("reply", text_field.value); // send the form via AJAX var xhr = new XMLHttpRequest(); xhr.open('POST', e.target.action); xhr.setRequestHeader("X-CSRFToken", get_cookie('csrftoken')); xhr.send(form_data); } What's the best pattern to catch and display validation errors under such circumstances? Would love to see an illustrative example of how the experts do it. Note: I prefer pure JS at this point since that's what I'm starting with. JQuery's on my radar, but I'll look … -
