I have written the code for file upload but it is not displaying on my destination page.
Please help me edit my code or suggest how to fix this issue.
The rest of the fields are displaying but not the file field
My models.py
class Help(models.Model):
researcher = models.CharField(max_length=100)
study = models.CharField(max_length=500)
date = models.DateTimeField(auto_now_add=True)
document = models.FileField(upload_to='documents/', null=True, blank=True)
forms.py
from django import forms
from .models import Help
from django.forms import ModelForm
class AboutHelp(forms.ModelForm):
class Meta:
model = Help
fields = '__all__'
source page
<form action="{% url 'lazer.views.about_experiment' exp.link_name %}" method="POST" name="form">
{% csrf_token %}
<label>Researcher Name(s):
<input type="text" name="researcher"><br>
<lable>Study Summary
<textarea rows="10" cols="50" placeholder="Start typing..." maxlength="500" class="form-control" name="study"></textarea>
<br>
<label>Upload your IRB approval letter:
<input type ="file" id="irb-file" class="file_input" name="document"></label>
<br>
<input type = "submit" value="Submit" class="btn btn-primary" />
</form>
views.py
def about_experiment(request, ex_link_name):
researcher = None
study = None
posts = None
exp = get_object_or_404(Experiment,link_name = ex_link_name)
high_scores = ScoreItem.objects.filter(experiment=exp,active=True)
context = {
'request': request,
'exp':exp,
'high_scores': high_scores,
'awards':AwardItem.objects.filter(experiment=exp,visible=True),
}
if exp.about_file:
context['about_file'] = settings.EXPERIMENT_DIRS+exp.about_file.get_include_path()
return render(request, 'about_experiment.html', context)
if request.method == 'POST':
form = AboutHelp(request.POST, request.FILES)
posts = Help.objects.filter().order_by('-date')[0]
if form.is_valid():
obj = form.save(commit = False)
obj.save()
researcher = form.cleaned_data['researcher']
study = form.cleaned_data['study']
document = form.cleaned_data['document']
else:
form = AboutHelp()
posts = Help.objects.filter().order_by('-date')[0]
return render(request, 'about_experiment.html', {'posts': posts})
return render(request, 'about_experiment.html', {'posts': posts})
destination page
<h4><b>{{ posts.researcher }}</b></h4>
<p>{{ posts.study }}</p>
<p>Uploaded file is : {{ posts.document }}</p>
