    <p>I'm trying to create a simple upload form for my project in <code>Django 1.5</code> an <code>Python 2.7</code>.</p> <p>This is my <code>File</code> class:</p> <pre><code>class File(models.Model): middleschool = 'MS' highschool = 'HS' university = 'U' blank = '-' school_choices = ((middleschool, 'Middle School'), (highschool, 'High school'), (university, 'University'), (blank, 'Not defined'),) name = models.CharField(max_length = 30, primary_key=True, blank=False, null=False) description = models.CharField(max_length = 140, blank=False, null=False) school = models.CharField(max_length = 30, choices = school_choices, default = blank) subject = models.ForeignKey(Subject) user = models.ForeignKey(User) rating = models.DecimalField(max_digits=2, decimal_places=0, default = 0) price = models.DecimalField(max_digits=2, decimal_places=1, default = 0, blank=True, null=True) file = models.FileField(upload_to= "/file/") </code></pre> <p>this is the form:</p> <pre><code>class UploadFileForm(forms.Form): middleschool = 'MS' highschool = 'HS' university = 'U' blank = '-' school_choices = ((middleschool, 'Middle School'), (highschool, 'High school'), (university, 'University'), (blank, 'Not defined'),) name = forms.CharField(max_length = 30, required = True) file = forms.FileField() description = forms.CharField(max_length = 140, required = False, label='Breif description of the files content') school = forms.ChoiceField(choices = school_choices, required=False, label='What level is the material that are you uploading?', initial = blank) subject = forms.ModelChoiceField(queryset=Subject.objects.order_by('?'), required=False, label='What subject this file is about?') price = forms.IntegerField(required=False) </code></pre> <p>this is the view:</p> <pre><code>def upload_file(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): new_file = File(file = request.FILE['file']) cd = form.cleaned_data new_file.name = cd['name'] new_file.description = cd['description'] new_file.school = cd['school'] new_file.subject = cd['subject'] new_file.price = cd['price'] new_file.rating = '0.0' new_file.user = request.user new_file.save() form = Search() return render(request, 'home.html', {'form': form, 'request': request}) else: form = UploadFileForm() return render(request, 'upload.html', {'form': form, 'request': request}) </code></pre> <p>and this is the relative <code>HTML</code></p> <pre><code>{% if request.user.is_authenticated %} &lt;form action="" method="post"&gt; {% csrf_token %} {{ form.as_p }} &lt;input type="submit" value="Upload"&gt; &lt;input type="reset" value="Reset"&gt; &lt;/form&gt; {% else %} &lt;p&gt;You must be logged to upload a file&lt;/p&gt; {% endif %} </code></pre> <p>My app path is: <code>C:/Users/User/Desktop/site_is/app_is/</code> and I want hose files saved in the folder: <code>C:/Users/User/Desktop/site_is/app_is/static/file/</code>. In my <code>Setting.py</code> I set:</p> <pre><code>MEDIA_ROOT = 'C:/Users/User/Desktop/site_is/app_is/static/file/' MEDIA_URL = '/file/' STATIC_ROOT = 'C:/Users/User/Desktop/site_is/app_is/static/' STATIC_URL = '/static/' </code></pre> <p>The problem is: when i select the file and hit the upload button the <code>FileField</code> empties itself and the form raise an error since that field is required.</p> <p>I fear I'm doing something wrong with the media/static paths in the <code>Setting.py</code> because the view syntax it's the same as the one in the <a href="https://docs.djangoproject.com/en/dev/topics/http/file-uploads/#handling-uploaded-files-with-a-model" rel="nofollow">Django docmentation</a> but I really don't know how to solve this problem.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
