But unfortunately, i encounter the same error : Could not parse the remainder: ' = json.loads(entry.saved_data)' from 'everyEntry = json.loads(entry.saved_data)' Here is my code from the template : <tbody> <tr> {% for entry in entries %} {{everyEntry = json.loads(entry.saved_data)}} {{ everyEntry.items}} {% for clef, valeura in headersLoop %} {% for chiave, valore in everyEntry %} {% if clef = chiave %} <td> <p>{{clef}} {{valore}}</p> </td> {% endif %} {% endfor %} {% endfor %} {% endfor %} </tbody> An at this line : {{everyEntry = json.loads(entry.saved_data)}} the problem occurs. How may i fix this ? Thank you guys. -
I have a bound ModelForm that is invalid
I am trying to create a ModelForm that links to an external database, and when you submit the form the external database gets updated. The problem comes when I check the validity of the form, it is invalid. I have done some researching into this and found the most common problem was that the form is not bound, but when I use print(form.non_field_errors) I get: <bound method BaseForm.non_field_errors of <EmailForm bound=True, valid=False, fields=(subject;body;name;altsubject;utm_source;utm_content;utm_campaign)> models.py: class MarketingEmails(models.Model): messageid = models.AutoField(db_column='column1', primary_key=True) subject = models.CharField(db_column='column2', max_length=2000) body = models.TextField(db_column='column3') #using a text field as there is no maximum length name = models.CharField(db_column='column4', max_length=25) altsubject = models.CharField(db_column='column5', max_length=2000) utm_source = models.CharField(db_column='column6', max_length=25) utm_content = models.CharField(db_column='column7', max_length=25) utm_campaign = models.CharField(db_column='column8', max_length=25) class Meta: managed = False db_table = '' forms.py: class EmailForm(forms.ModelForm): class Meta: model = MarketingEmails fields = ['messageid','subject','body','name','altsubject','utm_source','utm_content','utm_campaign'] views.py: def emailinfo(request, pk): if request.session.has_key('shortname'): shortname = request.session['shortname'] rows = get_object_or_404(MarketingEmails, pk=pk) if request.method == 'POST': form = EmailForm(request.POST) print(form.errors) print(form.non_field_errors) if form.is_valid(): form.save() print("form is valid") return redirect('marketingemails:emailinfo', pk = rows.messageid) return render(request, 'marketingemails/emailinfo.html',{'shortname': shortname, 'rows': rows}) else: return HttpResponseRedirect(reverse('common:login')) urls.py: app_name = 'marketingemails' urlpatterns = [ url(r'^marketing/emails/(?P<pk>[0-9]+)/$', marketingviews.emailinfo, name='emailinfo'), ] html: <form method="POST" class="post-form" action =""> {% csrf_token %} <label for="exampleTextarea">Name</label> … -
Automatic inheritance for django models
I have a django project which has models like this. class Part(models.Model): attr1 = models.CharField(max_length=50) attr2 = models.CharField(max_length=50) class Document(models.Model): part = models.ForeignKey(Part) attr1 = models.CharField(max_length=50) and so on. There are a lot of models in one single module and I need for each model a separate model with the same attributes plus one or more additional attributes. How would I do that without writing every single class by hand? -

Django calls other template instead of default

Django - Wrong Validation Error Message when using self-written Validator
I have written my own validator as I have several fields in my form where the same validation is applicable and I wanted to reduce my code with clean_field() methods. My Form looks like this: class EducationProjectAjaxForm(forms.Form): study_fees_year_1 = forms.IntegerField(required=False, validators=[validate_study_fees]) study_fees_year_2 = forms.IntegerField(required=False, validators=[validate_study_fees]) study_fees_year_3 = forms.IntegerField(required=False, validators=[validate_study_fees]) study_fees_year_4 = forms.IntegerField(required=False, validators=[validate_study_fees]) My validator looks like this: def validate_study_fees(data): if data: if data > 100000: raise ValidationError(_('Falscher Wert: %(value)s'), code='invalid', params={ 'value': 'Es sind maximal 100.000 € Studiengebühren pro Jahr erlaubt.'}, ) if data % 10 != 0: raise ValidationError(_('Falscher Wert: %(value)s'), code='invalid', params={ 'value': 'Der eingetragene Wert muss durch 10 teilbar sein.'}, ) if data < 0: raise ValidationError(_('Falscher Wert: %(value)s'), code='invalid', params={'value': 'Der Finanzierungsbedarf darf nicht negativ sein'}, ) return data My problem is that even though the validation itself is correctly applied I get the wrong error message: "Please choose a whole number". The message comes probably from the normal validation for IntegerFields but something like 123 throws the same message even though it is a whole number. If go the way with clean_study_fees_year_1(self), ... The error message is correctly shown. Is there something to fix my problem so I can have cleaner code? Thanks in … -

Django get id of specific div class
I am trying to build up a website with Django which showes the web-traffic of another website in realtime. Though the user shall be able to sort the data in a view different ways I would have to make a huge amount of nested folders in my project folder and I don't think that is the best solution for it. I have another idea and therefore, let's say we have created a website which contains following code: ... <div class='size' id='big> <div class='fish' id='yellow'> <a href='some_link'> LINK </a> ... For dynamically changing the site I need to know the ids of the size- and the fish-class. Is there any possiblity to get the ids of the div-classes (with Django) when the link is pressed? Something like (pseudo-code): id = request.get_id_of(div class='fish') BeautifulSoup is no solution for this problem because it's getting some conflicts with Django. -
