django form to upload file returns error as form not valid - forms

Question

I am developing an app in Django.
My users are allowed to save data by compiling a form like this
Tool:
acronym:
definition:
defined by the following function, in forms.py:
class tool_form(forms.ModelForm):
class Meta:
model=tool
fields=["Tool", "Acronym", "Definition"]
That saves the data into a model like this:
class tool(models.Model):
Tool = models.CharField(max_length=256, blank=True, null=True)
Acronym = models.CharField(max_length=25, blank=True, null=True)
Definition = models.TextField(blank=True, null=True)
The view function allowing this, is:
def add_tool(request):
if request.method=='POST':
form = tool_form(request.POST or None)
if form.is_valid():
form.save()
messages.success(request, ("Submit succeed!"))
return redirect('adding_tools')
else:
messages.error(request, ('ERROR: submit failed'))
return render(request, 'adding_tools.html', {})
else:
return render(request, 'adding_tools.html', {})
Now I want my users to be able to copile many times of the same form, all at once.
In order to achieve this, I am allowing my users to upload a file copiled with the data to insert.
So I am allowing my users to download a template xlsx file with colums with given name
Column 1 name (cell A1): Tool
Column 2 name (cell B1): acronym
Column 3 name (cell C1): definition
To compile it, inserting many records, and then to upload it back.
So I want my code to save this data into the same model declared before (tool)
I am trying to achieve this by:
in template add_tool_sheet.html:
<form class="container" method="POST" enctype="multipart/form-data" >
{% csrf_token %}
<div class="file-upload-wrapper" id="input-file-now">
<small id="inputHelp" class="form-text text-muted">Select file to upload.</small>
<input type="file" name="uploaded_file" id="input-file-now" data-max-file-size="5M" class="file-upload">
<br><br>
<div class="form-group">
<input name="Date" type="hidden" class="form-control" id="date_to_turn_into_toda">
</div>
<button type="submit" class="btn btn-primary">Upload</button>
</div>
</form>
in forms.py:
class tool_file_form(forms.ModelForm):
class Meta:
model=tool_file
fields=["Tool_file", "Date"]
In models.py
class tool_file(models.Model):
Tool_file = models.FileField(upload_to='uploaded_sheets/', blank=False, null=False)
Date = models.DateField(blank=False, null=False, default=timezone.now().date() )
class Meta:
ordering = ['Date', 'Tool_file']
def clean(self):
if not (self.Tool_file or self.Date):
raise ValidationError("something went wrong")
def __str__(self):
return "%s ----- [%s]" % (self.Tool_file, self.Date)
in views.py:
def add_tool_sheet(request):
if request.method=='POST':
form = tool_file_form(request.POST, request.FILES)
if form.is_valid():
form.save()
messages.success(request, ("upload succeeded"))
return redirect('add_tool_sheet')
else:
messages.error(request, ('ERROR n1'))
return render(request, 'add_tool_sheet.html', {})
else:
return render(request, 'add_tool_sheet.html', {})
When I try to add new objects in the model tool_file from admin section, it works.
But when I try to add new objects from the user interface (template add_tool_sheet.html), it returns
ERROR n1
as message, and my console returns
GET /admin/ HTTP/1.1" 200 7381
Why?
Please note:
The upload from admin section works, the upload from user interface does not.

SOLVED
In template I put
name="uploaded_file"
but in order to match with the information in forms.py and model.py, it has to be:
name="Tool_file"
Now it works!
