Good afternoon, I need to rename the files that users upload through a form with the nomenclature (DSR_"rut"-"name"-"label name (from form)"-0-"extension"). The parts of the rut, the name and the extension I could already generate, but I don't know how to do the name of the label. example: if the label says "image": (DSR_"rut"-"name"-image-0-"extension").
Please your help.
To do this use the following:
def upload_directory_name(instance, filename):
ext = filename.split('.')[-1]
filename = "DSR_%s_%s_0.%s" % (instance.rut, instance.name, ext)
return os.path.join('uploads',filename)
The file forms is as follows:
class Candidato_form2(forms.ModelForm):
class Meta:
model = Candidato
fields = [
'certificado_antecedentes',
'hoja_de_vida_conductor',
]
labels = {
'certificado_antecedentes': 'Certificado Antecedentes',
'hoja_de_vida_conductor': 'Hoja de vida del conductor',
}
widgets = {
'certificado_antecedentes': forms.ClearableFileInput(attrs={"multiple":True, 'class':'form-control'}),
'hoja_de_vida_conductor': forms.ClearableFileInput(attrs={"multiple":True, 'class':'form-control'}),
}
As you can see in the docs the function passed to upload_to expects only two arguments. So, it is not possible to do with one function, you have to work arround it:
def create_path(instance, filename, file_type):
ext = filename.split('.')[-1]
new_filename = "DSR_%s-%s-%s-0.%s" % (instance.rut, instance.name, file_type, ext)
return os.path.join('uploads',new_filename)
def cert_upload_path(instance, filename):
return create_path(instance, filename, 'cert')
def hoja_upload_path(instance, filename):
return create_path(instance, filename, 'hoja')
class Candidato(models.Model):
...
certificado_antecedentes = models.FileField(upload_to=cert_upload_path)
hoja_de_vida_conductor = models.FileField(upload_to=hoja_upload_path)
Also, there is a problem with your form, namely ValueError: ClearableFileInput doesn't support uploading multiple files.. So, remove "multiple":True from widget attrs.
