How to take a uploaded file in django and pass to a function
Hi upload csv files in the media folder and now i want to take this files to pass a list in python to make a pdf. How can i call this files in a fucntion in django or there is a better way to do it?? This is how i upload the files: def subir_archivos(request): if request.method == 'POST' and request.FILES['myfile']: myfile = request.FILES['myfile'] fs = FileSystemStorage() filename = fs.save(myfile.name, myfile) uploaded_file_url = fs.url(filename) return render(request, 'subir_csv.html', { 'uploaded_file_url': uploaded_file_url }) return render(request, 'subir_csv.html') And the method to pass a csv to a python list: def csv_empresas(request): lista = [] with open('media/empresas.csv') as csvfile: lector = csv.reader(csvfile, delimiter=',',quotechar='|') for row in lector: lista.append(row) return render(request,'preparar_pdf.html',{"lista": lista}) -
Generate uuid for User Model id field
I am trying to extend a User model and add some fields and below is my approach Class UserProfile(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) mobile_number = models.CharField(max_length=20) gender = models.CharField(max_length=2, choices=GENDER_CHOICES) location = models.ForeignKey(Location, blank=True, null=True) class User_One(UserProfile): field_1 = models.CharField(max_length=20) .... .... class User_Two(UserProfile): field_1 = models.CharField(max_length=20) .... .... So basically there are two types of users User_One and User_Two and now whenever we save the two types of users in to database the following happens A User model record will be created with separate id of values 1,2,3 etc., A User_One model record will be created with id's 1,2,3 A User_Two model record will be created with id's 1,2,3 So for each every model record saving, django or database was generating id's 1,2,3. But i got a requirement that User model should generate a uuid for id field value in place of integers, was that possbile ? I mean something like below class User_Profile(models.Model): id = models.IntegerField(default=uuid.uuid4) -

Django points to different locations for static files
I have deployed django website on debian 8 vps. The static files are held in static folder witch is at the same level as the app folder. The server can reach them on debian VPS. However the development version is located on Windows10 machine. The files are identical (cloned git repositories) but in the developement version tI get 400 when I try to reach my static files. From my setting.py file: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) STATIC_URL = '/static/' STATIC_ROOT=os.path.join(BASE_DIR, 'static') -

The effect is that now development server sees the files and deployed version does not (i.e. it displays raw html without any css styles) - so exactly the opposite to the previous situation. I am out of ideas. (maybe it has something to do with the fact that at certain point I did collectstatic so I have static folder in two locations???) -

Wagtail Recaptcha Localhost - SSL: CERTIFICATE_VERIFY_FAILED

I can do the google captcha just fine, but once I hit submit I run into an error.

I need to concatenate two strings inside a static tag, i checked previous question about how to concatenate strings in django template and i found this answer, but when i used that solution, the broser (Firefox) doesn't show the image. Details: This is my code: {% with "images/my_twitter_wordcloud_"|add:user.id|add:"png" as image_static %} <center> <img src="{% static 'image_static' %}" width="650" height="350" style="margin-left: 10%;"/> </center> {% endwith %} When i ckecked the inspector in the browser, it showed the image like this: <img src="/static/image_static" style="margin-left: 10%;" height="350" width="650"> I think that it should be: <img src="/static/images/my_twitter_wordcloud_"|add:user.id|add:"png" style="margin-left: 10%;" height="350" width="650"> I checked the django documentation about add reference, and i tried using "" and "" after add, but It seems like django doesn't interpretate the variable, what i'm doing wrong?

Applying bootsrap and custom css to {{form}} elements in django

I am referencing this solved question: CSS styling in Django forms` using the answer I created my forms.py page as follows: from django import forms from .models import ContactInfo class ContactForm(forms.ModelForm): # class meta brings in the fields from models class Meta: model = ContactInfo # grab the fields from models ContactInfo class fields = ('Fullname') # specify which bootstrap class each html widget should take def __init__(self, *args, **kwargs): super(ContactForm, self).__init__(*args, **kwargs) self.fields['Fullname'].widget.attrs.update({'class': 'form-control'}) html using {{form}} elements: <div class="form-group"> <label for="id_Fullname">Full Name:</label> {{form.Fullname}} </div> The working html w/o usage of {{form}}: <div class="form-group"> <label for="fullname">Full Name:</label> <input type="text" class="form-control" id="fullname"> </div> How do I get the "label" tag to point to the id inside {{form.Fullname}}.
