django form field - how to present the value in a form template

Question

Hi,

I have a model with a FileField which is shown below. I use this model in a model form.

receipt  = models.FileField(upload_to='receipt/%m-%Y/', max_length=255)

I can save the object and the receipt field contains the file url.

Now when I present this object with the model form the file url is not presented, instead a message "no file chosen" is presented.

This is the html template I m using for the form:

<table  cellspacing="5">
 {{ cash_expenditure_form.as_table }}
</table> 

and the form that I'm using:

class CashExpenditureForm(forms.ModelForm):

class Meta:
    model = CashExpenditure
    exclude = ('project','paid', 'paid_check','invoice','cash_expenditure_selection')

When I check this object in the admin the field url is presented as expected. Thus I think something is missing in the html form template.

Solution:

AdminFileWidget does the trick ;-) easy as always..

I'm not sure you can pre-fill file selection field.

The file input type creates a field through which users can upload files from their local computer or network. The VALUE attribute specifies the name of the initial file, but it is typically ignored by browsers as a security precaution. The ACCEPT attribute gives a comma-separated list of media types accepted, allowing the browser to filter out inappropriate files. Current browsers generally ignore the ACCEPT attribute.
